Rose and the others were responsible for sending away those who had not bought the city, while I was responsible for those guilds who bought the city. They took these people to see the cities they bought, and the presidents of the guilds were very satisfied. After confirming, the presidents returned to Aisinger and signed a final agreement with us.

After signing the agreement, I entertained them to the cafeteria for a meal. The auction time was quite short, and everyone was almost hungry, so they went to eat something to contact each other. My dad once told me that most of the business was negotiated at the dining table rather than at the negotiating table. The dining table can bring people closer to each other, and it is often easier to simplify complex things on the dining table. Now I am experimenting with this theory in Aisinger, and the goal is to buy the guild presidents of the city.

There was nothing special about a meal, but I turned it into a battlefield. After the meal, all the guilds participated in became our friendly guilds. It seems that my father's theory really makes sense. When everyone walked out of the canteen, the president of a guild suddenly asked: "President Zi Ri?"

"Yeah, what are you doing?"

"When I first came, I saw something standing around the corner of your city, which looked like a cannon. I was not wrong, did I?"

I asked in confusion: "Where did you see it?"

"I'm...!" The president turned around and couldn't remember which direction he was in. "Where is the teleportation array?"

"Over there." Aisinger had many teleportation arrays, but I knew he was talking about the one next to the auditorium because they came in from there. I pointed the direction: "Over there."

He immediately said, "I understand, it should be there."

"Then?" I took out the leaves of the city tree, and the leaves immediately lit up.

"Is there anything?" The city tree had already sensed the leaves on my side, and the sound came out of the leaves, which scared the people around.

"Someone just told me that the cannons were found in the southern section of the second city wall. Do you know what's going on? Shouldn't all cannons be collected into the artillery room now? Why are they still on the city wall?"

The City Tree replied calmly: "I know that I raised it. The gun position No. 36379 in the southern section of the second wall had a mechanical failure. It is under emergency repair, so I raised it for easy maintenance. I have any problems?"

"It's okay, I just asked. By the way, light up the place where I am, and the street lights here are gone!"

“This is according to your requirements, in order to save energy, do not start auxiliary lighting at night in non-combat states.”

"One special case tonight, help me turn on the lighting."

"I understand. The power furnace is warming up and the lighting is started after 20 seconds. Is there nothing else?"

"No more." I put away the leaves and said to the president: "You are right, that's a cannon." I suddenly found that no one was listening. They were all looking at both sides of the road, as if waiting for something.

I started with them and looked around and didn't know what they were looking at. After 20 seconds, I suddenly understood that they were waiting for lighting. The sound of the city tree came from the speakers in the city. "Please note that the Aisinger lighting equipment is started. To avoid partial overload, please do not start large equipment for the time being."

As soon as the sound ended, the spiritual gathering tower in the center of Aisinger suddenly emitted a green light from top to bottom. The entire tower was like a big glow stick emitting a majestic and terrifying light. The presidents around him made a marvelous sound at the same time.

After the Spirit Gathering Tower was launched, the streets in the city began to light up one by one, and soon arrived at our street. First, the end of the street lights lit up one by one, and the entire street became brightly lit as soon as it flashed.

A president came over and asked, “Is your city automated?”

“It’s not automatic, but npcs that are specifically responsible for control.”

"How do you hire such NPC?"

"I'm sorry, this npc is actually a tree. We all call him the city tree. As long as it takes root and sprouts in the city, he can control the entire city's equipment. I can communicate with him at any time as long as I hold his leaves. However, this tree is a rare variety and we don't have enough of it."

At first, the president who asked me about the cannon ran back. "Trees are rare varieties, cannons can always be produced, right?" The president said earnestly: "We are a small guild, not a large group like you. I established a village some time ago but failed to defend it, so the monsters were flattened! Now I have finally raised funds to buy a city. No one wants any more accidents, so we want to buy some cannons and go back."

He said this and the guilds around him were excited. "Yes! We also want to buy cannons..." Everyone was in chaos. Except for the Northern Alliance and those guilds with backstage, most guilds asked us to sell some cannons for them.

"Everyone, be quiet. Quiet..." They finally suppressed them. "Okay, let's do it. Cannons can be sold, but you have to let me send away those presidents who don't buy cannons first?"

After saying this, everyone became quiet. I quickly asked them to separate themselves and stayed for those who wanted to buy cannons. If they didn’t buy cannons, I sent them to the teleportation array first. I only ran back after all the guilds that didn’t buy cannons left. With these remaining guild presidents, I arrived at the museum of Aisinger, where all the models of our guild were parked.

"Okay. Since you want to buy cannons, let's talk about the issue of cannons. The place you are standing now is the museum front hall of our guild, which is all things that our guild can produce. This is just the foyer, and the cannons are in the left hall, come with me."

After entering the artillery display area, rows of cannons are unfolded in sequence. Each cannon has a detailed description of the ground, and there is also a video of the test-firing game next to it, so that everyone can see it intuitively. The presidents of the guild began to salivate when they saw these things, and they wanted to cross the railings and touch them.

Seeing their extreme performance, I had to be born to stop it. "That president, please step back a little. The isolation guardrail in front of you is crystal glass, but it can't stand it so crowded!"

"Oh! I'm sorry, I'm sorry!" The president quickly retreated.

The exhibition hall is long and the cannons are placed on both sides of the exhibition hall. Some presidents ran to the farthest artillery booth. "President Zi Ri, how much does this kind of cannon cost?" This is our guild's own exhibition hall, not for selling things, so the explanation does not include the price.

I took a look and said, "Good guy, these people are really good at picking. The one they are referring to is not only the magic crystal cannon, but also the biggest one. "Don't look at that. Come and see the cannon here."

"Why?" the elders said angrily: "President Zi Ri, you are not authentic now! We think you are friends, but you are blocking them. You obviously refuse to sell the best place when you sell cannons. What do you mean?"

I was not angry, but smiled and said, "Don't be angry, I didn't make it clear. There are indeed many cannons here, but the prices vary greatly. The one you are looking at is a magic crystal cannon, and it is the most powerful model so far. Like the micro-city city you bought, if you get 5 rounds, the city will no longer exist."

The people over there were so many tongues stuck out their heads. "Is that powerful?"

I walked over there and said, "It's because it's too powerful. The output is not high. Moreover, this is a special cannon, not a regular weapon. It's a waste to buy it back."

The president was still very stubborn. "I just like it, how much do you think?"

"If you insist on buying, I can't do anything. Since you bought our city, I will also give you discounts on this gun."

The president immediately smiled and said, "Thank you, thank you."

I took out an abacus and pulled it out and said, "The material cost of a giant magic crystal cannon is 30 million crystal coins, the labor cost is about 15 million crystal coins, the loss of production equipment is 5 million crystal coins, the vocational cost of technical patents is 30 million crystal coins, and the energy consumption during production is about 1 million crystal coins, and these are 81 million crystal coins in total. Military material systems have to collect taxes of 50% of the production cost, which is 40.5 million crystal coins. In other words, a giant magician has to be levied.

We have to bear the cost of 121.5 million crystal coins when we build the crystal cannon. Although we have to give you discounts, I can't work for you in vain. Our production equipment is also very busy now. If you produce the cannon, we have to stop our plan. You have to bear this loss. The sales price of arms is generally 10 to 20 times the cost price. I only charge you twice, that is, 243 million crystal coins per cannon. When fired, the magic crystal cannon will consume the energy of the magic crystal. You can dig the magic crystal yourself or buy it with others.

Otherwise, I can buy it with me. If you buy it with me, I can give you a discount price. The price sold in the system city is 6 million crystal coins per kilogram. I know an npc and can get an internal price of 5 million yuan per kilogram. I charge you 5% of the agency fee, and 5.25 million crystal coins per kilogram to sell it to you. This is the lowest price. I also have to get a kickback to that npc. I can't get a copper plate myself, but it's just for everyone's friends to help you in vain. In addition, the future maintenance of the Magic Crystal Cannon,

I can do it for free, but if you need to replace the parts, you have to pay for it yourself. If you decide to ask for it, you will pay a 20% deposit, which is 48.6 million crystal coins. I will start the factory immediately and it will be completed tomorrow. We will deliver the goods to your doorstep and you will pay the remaining balance. What do you think?" After I finished dialing the abacus, I looked up and the man disappeared. "Strange! Where is the person?" He lowered his head and saw the guy lying on the ground foaming at his mouth. "Ah, why have you been on the ground? It's not epilepsy?"

Actually, the words just now were deliberately scaring him. The cost of the giant magic crystal cannon was not that high. The deposit I asked him to pay was enough to build two cannons. However, I couldn’t sell this super weapon easily, so of course I had to add it hard. He didn’t buy it, and I wouldn’t be afraid if he bought it. With his money, I could build another 20 doors. Will 20 doors not be able to deal with one? As for the leak of technology, don’t worry. The technology of the magic crystal cannon was created from the Dark Temple, which means that it is the system setting technology, and not everyone can imitate it. As for other cannons, there are magic marks specially made by Vina for me. If anyone dares to dismantle it, please be ready to fly to outer space.

After I was scared by this, the presidents were indeed honest. What I introduced them and what I saw, and what I didn’t introduce them, they didn’t think about it at all. Take them to visit a cannon we used to produce. "You see now that this is the cannon we used to produce, specially installed on warships to fight fortress cannons, so their power and range are very good. If you really want to buy cannons, I suggest you buy this. The warships of our guild are basically equipped with cannons, and the production equipment of this cannon is in a semi-idle state, so it can be produced quickly without squeezing resources." I took out the abacus and pulled it out. "Let's do this. Each cannon has 1 million crystal coins. Another 100 shells are given. Do you think it's okay?"

"Can this gun deal with enemy artillery?"

"Just kidding! This is a naval gun specifically for the fortress cannons. Do you think it can be used against the enemy's ground cannons?"

Another president asked: "What should I do if the shells are used up? How to buy the 100 rounds I sent? There is also after-sales service, how to calculate the maintenance problem?"

"There are many types of shells, but you use them on land, so you can't use them. I recommend you to buy two types of shells, one is high-explosive incendiary bombs, which are specially used to deal with enemy siege weapons, and the other is shrunk bullets. They are specially used for ground personnel. The incendiary bombs are a little more expensive, with 30 crystal coins per round, but this thing is not much used. A city only needs to prepare thirty or fifty rounds. The price of shrunk bullets is 20 crystal coins per round, which is cheap, right?"

"Yeah. Not bad. The shells are very reasonable." A president nodded and said, "I know a guild that they cannot produce cannons, but they can produce shells themselves. The shells they sell cost more than 70 crystal coins per round. They are much more expensive than yours."

A man asked in a low voice: "Isn't it because of quality problems with your shells so cheap?"

"You can rest assured about the quality and absolutely reliable. Our shells are cheap because we have a line of shells, which is fast and consume less, so the cost is low. Low costs are naturally cheap."

“What about the repairs?”

"We are responsible for repairing the artillery itself. We bear the cost and it is for door-to-door service. If it is not repaired well, please change it to you. If it is destroyed by the enemy in any way, it is your own. You will pay for all repair costs. We only charge for replacing parts, and labor costs are exempt. However, you must be responsible for sending the artillery to us. We don't care about door-to-door repairs!"

"Not bad, very reasonable." The president said: "I want 50 guns, and in addition to the guns, I will give me 1,000 incendiary bombs and 100,000 shrapnel rounds."

"I want to... too!"

“…”

"Don't worry! Come one by one!"

The Array Helper is like a madman. He snatches hard. It's not that he doesn't have enough points! In the end, I calculated that in addition to the cost, these cannons and shells made a net profit of 15 million crystal coins. In fact, these cannons were sold overnight. I told them that they were produced overnight at night, but they were actually refurbished overnight. These cannons were eliminated from previous warships. Anyway, they still took up space, and they could make a little money after selling them. Although these cannons were eliminated from our land, they didn't use them for a long time. And they were still very advanced compared to other countries' artillery, so they would not suffer any loss when they bought them back. I told them that these are new weapons and they were a little happier. Anyway, this thing is better than the cannons of the system cities and other guilds. Even if they took them out and showed off, they couldn't see that they were eliminated.

At night, a large group of workers in the workshop of Gangcheng were busy with their feet facing the sky, and our artillery was being renovated. The barrels were re-tied with metal planers, so that they would shine. The barrels had to be turned over and walked them all with wire brushes, so that they would leave some marks in the chamber, but not many. At that time, I will tell them that when we left the factory, we tested two shells for each gun in order to ensure quality, so there was a little mark in the chamber.

Today is a great harvest. Not only did I sell so many dangerous cities like hot potatoes, but I also dealt with the eliminated cannons. Su Mei just came to tell me that the centralized city used to make a name for me has been completed, so I asked me to go over and take a look. I am in a good mood now and went to visit the 12 satellite cities and central cities. Overall, these cities have been well built. The City of Honor has been expanded by nearly half, and now it is about the same size as Yunxiao City. The city wall has been raised to 50 meters and the thickness has been thickened to 40 meters. We have designed 6 city gates. After all, there are too many 12 canyons.

The mountains outside the City of Honor have been processed into 70-meter-high vertical cliffs, and each cliff top is a city. In order to prevent the enemy from climbing, Sumei asked the Mage Gate to mirror the mountain, and then brushed some lubricants on the warship bearings. Now this cliff will slide down even if it falls on it. It is said that in order to prevent the enemy from digging holes in the mountain, they also strengthened the rocks permanently. These rocks are hard like steel plates, which are very expensive but really strong.

These satellite cities do not have civil buildings or city walls. They are originally the top of the mountain. It is meaningless to have a city wall. There are turrets in the city, and there are ammunition depots and a small number of command rooms inside the mountain. This design is to make the best use of the goods on the basis of saving, and it is used to make up for the numbers anyway, so it is a waste to have civil buildings.

After the tour, we returned to Aisinger, but unexpectedly someone was waiting for me here.

"Emperor Atlantis, the White Shark Clan? Why are you here?" It's really strange that these two enemies who have been with Esinger for many years appeared at the same time. "You won't have any conflicts again, right? Didn't you send someone to help you coordinate during this period of time when I was away? Did the negotiations fail?"

The White Shark Clan leader smiled and said, "No, Miss Bingbing helped our tribes coordinate the negotiations when you were not here. Our negotiations were very successful. Now our tribes decided to put the city together and merge them."

"Merge?" Why do these two old guys like to go to extremes? They were still alive and dead some time ago. Suddenly they became brothers!

Emperor Atlantis said: "It is mainly because the city of Atlantis is damaged too seriously, and the invasion of the Shermo tribe made us very scared. Even if Atlantis is rebuilt, we still can't defend it."

The White Shark Clan Chief also said: "So too. Last time we barely defended the offense, but lost a large number of people. Sooner or later, it will be over. So we want everyone to live together. The combination of the specialties of the two clans should be able to withstand the invasion of the Shemo clan."

I said why these two old slip-ons suddenly became brothers? They had to unite after a long time because the enemy was too strong. The two tribes were like two countries. It is said that even if both sides agreed, it would take a long time to complete it. They solved such a complicated thing in just a few days because objective conditions forced them to destroy the tribe. At this time, survival overwhelmed everything, and politicians didn't need to talk about it anymore. They just merged first, and other things were easy to say.

I looked at the two of them and said, "It is a good thing that you plan to merge. At least it is more convenient for me to provide assistance. You will not say who I am biased towards. So what are you looking for me now? Are there any requirements?"

"No, no, no," said Emperor Atlanticus: "This time we came for your benefit."

"For me?" I laughed: "Tell me."

The White Shark Clan leader said: "That's right. The two of us found a place to rebuild the city, and the two of us lived together in the future. But suddenly it was lifted into an island by a powerful force."

"You mean the seabed has risen there?"

"It's not the entire seabed, but that part, a very regular figure, suddenly rises like a pillar, completely straight up and down."

"Road up and down? Isn't that like a skyscraper built on the bottom of the sea?"

The White Shark Clan leader immediately nodded and said, "Yes, you describe it very appropriately. It's like a super building built on the bottom of the sea, and the top floor extends out of the water."

"This kind of place is very suitable for a base." I suddenly remembered. The White Shark Clan leader said that it was suddenly raised by a powerful force. Could it be... "Did you go to the island to see it?"

Atlantis said, "We know you can guess it. It's a good idea. It's indeed a man-built base. The entire island has become a city. The outer periphery is full of ports. Our scouts saw a large number of warships. And the flag of the warship is a red circle on a white flag."

"Japanese?"

The White Shark Clan leader said: "I have also been in contact with the Japanese before. They used magic crystal stones to buy our technology. After the people sent by Atlantis came back to report, I immediately knew that it was the Japanese base, and there was the guild that traded with us at the beginning."

"You mean Black Dragon?"

"right."

I thought about it and asked, "Where is that island?"
To be continued...
