"It should be right here." The mage said after taking the map and comparing for a long time.

The strong man looked around and said, "But the area of ​​this place is not small! Didn't the map say where it is?"

"If you know, you don't have to bring so many people to find you." Cook said, throwing a shovel to the strong man. "Go dig around. Since there is a mission, there must be clues nearby."

"Oh, it's true. My big bear has actually fallen into being a miner!"

"What? Do you despise miners?" Cook asked in a bad tone.

"Hehe, I'm not talking about you." The strong man said, then raised the shovel in his hand and smiled dryly: "Dig a hole!"

After the strong man and Cook started digging holes, the mage also asked the others around to start digging holes together. This was the first time I saw more than 400 people digging holes together. Although there were more people in Aisinger digging trenches before, I was robbing materials everywhere all day long, and I didn’t see any digging holes at all.

I have to say that although these Russians' methods were a little stupid, the effect was very good. It took about two hours to dig from the afternoon to the evening. The group finally found clues at the last moment when the sun set.

When a npc shoveled down without shoveling out the stone, it bounced up the shovel, and an echo similar to the sound of metal impact came from under the ground. "Captain, there is something happening here." The npc shouted immediately after finding that the situation was wrong.

After digging for more than two hours, Cook and the others were already annoyed. Now, when they heard that there was something wrong, everyone threw the shovel and rushed to the npc who was shouting.

"Did you find something?"

"I don't know yet, but I didn't shovel it just now, and it seemed like there was metal underneath."

"Metal?" The mage quickly called the strong man over as soon as he heard this. "Big Bear, come and dig."

"Okay." After agreeing, the strong man quickly took the shovel and started digging, but he also shoveled the metal after he shoveled down. After Cook reminded him to dig along the surface soil, he lifted up a large area around him.

Originally, Cook and the others thought that the things they dug were not too big, but what they didn't expect was that with the cleaning of Big Bear, the exposed part of the metal under the ground was actually part of a door panel.

"This seems to be a door?" Big Bear said, looking at the small area he dug out.

"There must be an authentic tunnel below, this is probably the entrance to the authentic tunnel." The master said: "It seems that we have found the right one. Let's go up together and dig out the entrance, hurry up."

Under the order of the mage, the stronger people around began to dig the soil, while the mage, who was fine, lit the lighting technique to illuminate them. With the efforts of several people who were digging, the ground was quickly opened up, but they became more and more frightened.

Originally, the wizards and the others thought that what they dug out was just part of the door, and everyone thought that they could dig out the entire door soon and open it. However, as everyone digs, the exposed part showed the area of ​​the door a bit scary. The reason they thought this was the door was mainly because they found the door knocker, but now they found that it was not the door knocker at all, but the decoration on the door. This huge pure copper door panel was neatly inlaid with huge door knocker, just like the copper nails inlaid on the gates of ancient Chinese palaces, but rings were hung on the copper nails here.

"Is this thing for giants? It's too big, right?" Looking at the part that had been dug out, Big Bear said in surprise: "Based on this volume, this door is at least thirty meters wide!"

"No, we are standing in the wrong direction." The master said: "Thirty meters is the height of a door panel. The Chinese doors are double door panels that are open in both sides, and the door height is generally slightly shorter than the width. This door panel should be thirty meters high, and the width of a single door panel will not be lower than forty meters, otherwise it will not meet the construction habits of Chinese people."

"Then isn't this gate more than 80 meters wide?" Big Bear asked in surprise.

"This is not necessarily the case," Cook said. "Although construction habits generally don't change much, this thing is a thousand years ago after all. Do you know what specification it was built? But one thing is certain, this door is definitely not much smaller."

As Cook said, this door is not much smaller, and after they completely cleared the door, they found that the door was not built as they imagined. In fact, this door was neither opened horizontally nor vertically, but opened in four directions. It was confirmed that the entire door was composed of four door panels, and the gap in the middle was just a horizontal h-shaped lying horizontally, and this door was not an ordinary open-closing door panel, but a telescopic one. The bottom of the door was a wide one.

For a whole door panel of 100 meters and 30 meters high, the door panel is opened by descending, rather than opening inward or sliding left and right. On the bottom door panel are two door panels that are fifty meters wide and 30 meters high. After these two door panels are combined, they are exactly the same as the door panel below, but they are composed of two boards, and the opening method is sliding to both sides. As for the top door panel of the door, its structure is exactly the same as the bottom one, but the way it opens is to rise.

The four door panels are composed of a rectangular gate that is 100 meters wide and 90 meters high. However, this gate is not vertically on the ground, but is tilted at a thirty-degree angle according to the trend of the hillside and the horizontal plane. It is also covered with a layer of soil and rock. The NPC dug before was actually the top of the door, which is the thinnest part of the soil layer, so after digging two shovels, it touched the door panel, and the bottom of the door below was almost buried more than two meters deep. If the door panel above had not been extended all the way down, it would have been really not easy to find it from the bottom of the door.

In order to dig out the door intact, Cook and his team kept digging from the sun that it was almost ten o'clock in the evening, thanks to the large number of people. Otherwise, it would be not that easy to completely dig out such a large door.

After finally opening the door completely, the mage immediately took the map and searched the door. Finally, he found a small hole in the middle of the top of the door. This small hole that could not even fit into the human arm was too small relative to the size of the entire door, so if you don’t pay attention, you can’t find it.

After the mage discovered the small hole, he immediately rolled up the map in his hand into a scroll, and then looked down and stuffed it into the hole. When the scroll completely penetrated the hole, he heard a sound of metal hitting, and the copper rings hanging on the copper nails on the entire door suddenly stood up.

"Okay, the gate has been started, and the problem of unlocking is below." The mage stood up and said.

"Don't tell me this is a password lock." Cook said with a bitter look at the standing copper rings. However, although he didn't want this, the mage still told him an answer he didn't want to hear.

"That's right, this is a password lock, but a three-dimensional password lock, which is much more difficult than opening a safe." The mage said, pointing to the copper rings and said, "These copper rings are all standing up now, but we can manually tilt the rings upward by 90 degrees or downward by 90 degrees, or twist the copper rings so that the copper nails under the copper ring can rotate at a certain angle. The copper rings themselves also have scales. Turning the copper rings to change the scale displayed on the connection point with the copper nails is also part of the password."

Big Bear looked at one of the rings and exclaimed: "Damn it, right? The three angles of the upper, middle and lower door rings are equal to three possibilities. There are six gears in the rotation angle of the copper nails. The combination of the two is 3 times 6 equals 18 possibilities. The copper ring itself has a circle of 36 scales, which corresponds to the previous 18 possibilities to form a total of 648 combinations. There are 648 combinations of this copper nail, and there are 89 times 99 on the entire door, and there are 8811 copper nails in total. Even if this door does not need to rotate the mechanism in sequence, these 8811 copper nails alone can combine more than 5.7 million combinations. Even if we don't do anything, don't expect to open this door for the rest of our lives!"

"It's not a quilt, even if it's a thousand lives, you don't expect it." The mage said: "Because this door requires copper rings to rotate in sequence, and the order is still carried out crosswise. It's useless to turn from where to where to where to in sequence."

"Such a complicated lock? How do we open it?"

The mage smiled proudly and took out another roll of bamboo slips from his body, then asked the two NPCs to completely unfold them and said with a smile: "In a complex lock, it's not a problem to have a password."

"Damn, you didn't say it earlier if you have a password. I thought you would try it one by one!"

Cook said from the side: "If I really don't have a password, I won't try it one by one. If I have that time, I might as well blow the door open quickly."

"You can't blow it up." The mage said: "This gate is connected to the protection array. The violent cracking requires three or above-level master gods to join forces to have hope. We will definitely not destroy it. If there is Zi Ri's Eternal Sword, you can consider it. I heard that there is a cutting law on that thing, which can cut off everything."

"Damn, his sword is worth a treasure trove, and there is no need to open this door if there is that thing." Big Bear urged: "You should read out the password quickly, I'll open the door."

"Don't worry, this door cannot be opened by one person. I'll arrange the people first."

The mage said that the rank of people is to let two hundred people stand on the door, and then direct them to guard the copper nails around them and then turn the copper rings by following the order. Although there are more than 8,000 rings on this door, most of them are useless. Only one thousand rings are needed to open the door. On average, each person needs to turn five rings, so the workload can be smaller. Moreover, because some rings need to rotate at the same time, and some have intervals, you will not have time to open the door even if you rely on one or two people alone to know the password.

After seeing that everyone is standing, the mage stands in the distance and holds a big horn and shouts at the password book, "Tork, go forward and grab the ring on your left. Harves, come down one square, yes, that ring, grab. I count one, two three, you two, press the ring down to the horizontal angle with the door panel, and the door knocker should automatically lock. After the rotation is completed, Harves, you must immediately turn the copper nail under the ring clockwise two squares, and you will stand up immediately after you turn. Tok, as soon as you see Harves stand up, you will immediately adjust the scale of the ring in your hand to eighteen, and it is OK to turn forward and reverse, but you only have five seconds, and all door knockers will automatically restore after the timeout.

When you reach the initial state, the front will turn completely in vain. That Rockel, pay attention to the ring at your feet, that is the one. Once Tok has turned, you must immediately push the ring upwards to parallel to the door panel, then quickly turn the scale on the ring to thirty, and then stand up and tell Harves loudly that you have finished. Harves, when you see Rockel's signal, immediately restore the ring you just turned to the zero scale state, and then push the copper ring up again to make it stand up. Only you have to run to the ring that is separated by one on your right side at the fastest speed, then push it upwards, and then tell Siwei loudly. Siwei, after you hear it,..."

The mage guided these players step by step for nearly an hour before explaining the order. However, the action may be too complicated, and it requires two hundred people to work together, so the error rate is really high. Even though they knew the order, they still tried it for more than ten times in a row but failed to open the door. And every time someone turned the error, all the previous steps would be zeroed, and the complexity was simply abnormal.

At first someone made a mistake, and the mage could hold a loudspeaker and call people to correct the mistakes everywhere. Later, he even shouted hoarsely, and the more than 200 people were all dizzy. Big Bear complained from the side: "I wouldn't have agreed to the team if I had known it, otherwise we would have stood up and each of us was responsible for a door knocker, so the steps would be much simpler."

"You think it's beautiful. Even if we don't have a team, we'll have to reduce the number of employees by at least a few hundred people when we passed through the forest before, but more people can be much faster." The mage said and sent all the remaining people. He only sent 200 people before because he thought it was a good arrangement. Unexpectedly, he underestimated the unexpected error rate after the crowds, so he has not completed it until now.

After all the people who were still present were sent to the battlefield, each of the more than 400 people was only responsible for two to three rings, which was much easier for everyone. However, even so, they still tried five more times to complete the correct steps. When the last person successfully turned the copper ring, with a bang, the gap in the middle of the door suddenly bounced open, and then the four doors began to rumble and slide toward all sides.

"Get down quickly, come down quickly!" Seeing that the door finally moved, the mage quickly shouted excitedly with his hoarse voice. But even if he didn't scream, these people would not stand still. After all, the vibration was very obvious when the door opened, and only fools would stand there in a daze.

As the door slowly slid open to the surroundings, a stream of light purple smoke rose from the door and then quickly spread around. Cook immediately screamed when he saw the color of the gas. "Everyone retreated and covered his nose. There might be something wrong with the smoke."

I don’t know if it was the smoke itself, or if Cook shouted in time, but after more than ten minutes, no one of the Russians fell down.

"It seems that there should be no problem. Let's go in now?" a player said to the mage and Cook and the other three.

Okumi originally planned to go in immediately, but before he could speak, the mage said first: "No, now pay attention. The npc army immediately set up a defense line to guard. The player divided me into two batches to eat and go to the toilet, and then came back to camp here to recover from fatigue. We will explore the underground passage tonight."

In fact, the mage himself had no choice but to make such a decision. They worked so hard that they finally found this place. Now they were just about to go in and explore it to complete the task. Who doesn’t want to go in and complete the task immediately? But the mage cannot make such a decision. He must suppress his desire and let everyone go offline to rest first. After all, in the original plan, they should have entered this underground passage last night, but due to many accidents, they have been tossing until now. Although the sun has not risen yet, it is not far from the sunrise. In other words, these people have been online for more than sixteen hours in a row, and after entering the underground passage, there will definitely be various dangers.

Almost waiting for them. If someone is forced out of the game by the system because of the physical fatigue in reality, it is not a good deal. So even though he knows that waiting for more than one day will make an extra day, the mage still makes the order to rest. As for why he camps in the game instead of sleeping directly in reality. First, although the camping state is sleeping, people are still online. The NPC responsible for the alert can wake them up at any time once it finds the situation. Second, the auxiliary dormant system of "Zero" itself is better than sleeping in reality. Even if camping in the wild cannot achieve the effect of sleeping in the city, it is still much better than sleeping in reality.

Standing on a mountain in the distance, I immediately understood their plans when I saw the Russians building a camp. After all, I have been following them for more than twelve hours alone. People like me don’t have to sleep. It’s nothing to be online for a long time. They are all ordinary people. If they don’t go offline for such a long time, they will definitely reach the physiological warning line. I guess if they don’t go to bed again, at least half of these people will be forced to be kicked off the line by the system within an hour.
