The ship is big and the target is big, and the chance of being hit is also greatly increased. While installing a crossbow, Zhao Bing also prepared to move the rocket onto the ship. The big place is so willful. While increasing the firepower, he removed all the eaves and hip roofs of the ship building, striving to be round and smooth, reducing the wind-receiving surface, and also reducing the chance of being hit. The portholes on the upper floor have also been changed to double, using lattice windows for ventilation and lighting. In wartime, another layer of thickened solid wood board is placed to seal the entire window to resist flying stones and arrows. At the same time, he also laid iron plates on key parts and covered with raw cowhide to increase protection.

The warship is huge and cannot be driven by manpower, so it can only rely on wind power. This ship uses four masts and six sails, with mats as sails, and can sail against the wind with the cooperation of the rudder board, but there are more sailors who need to drive the boat in this way. Zhao Bing calculated that one sailor would need about a hundred people, and it would take two hundred people to divide it into two shifts. With auxiliary personnel such as ship craftsmen, sailors, sail craftsmen, blacksmiths, etc., the sailors would need more than two hundred people.

"Lao Zhou, how are the fire measures on the ship done?" The hull is almost entirely made of wood, and it is just a bit like a fire. Not only should you be careful of the enemy's rockets and fireboats, but you should also be worried that you might accidentally catch a fire. He asked after turning around.

"Your Highness, don't worry. The fire places in the ship are protected. The partitions in the kitchen are built with bricks and stones, and the floors are replaced with ceramic plates. The lights in the cabin are covered with lampshades, and as long as you patrol carefully, there will be no accidents. In addition, each floor is equipped with a water draw gun and a large tank for water storage. In case of a fire, you can extinguish the fire in time. There are sandbags on the deck, so even if the enemy uses tinder oil, it can be wiped out by wet sand." Zhou Xiang said.

"The hull is huge. What if the enemy sends a fireboat to hit it?" Zhao Bing asked again.

"Your Highness, we have equipped so many crossbows. You can sink the fireboat in the distance or intercept it with a small boat. If you still rush forward, we can put down the pole and push the fireboat away so that it cannot get close to it." Zhou Xiang said, pointing to several long large woods placed on the side of the ship.

"Oh, it's so good to arrange this!" Zhao Bing nodded. At first he thought it was a spare mast, but he didn't expect it to be a support pole. He took two steps and asked as if he remembered something, "Hey, do we have cats on the boat?"

"Cat?!" Zhou Xiang was stunned when he heard this, and then reacted again, "Your Highness, this subordinate is ready to go to the ship just after the repair is completed."

"You are still considerate." Zhao Bing was very satisfied. He knew that not only people live on the sea boat, but also mice that were indifferent to the scattered food. They would bite the sails and cables to grind their teeth and spread diseases. In order to deal with them, only by raising cats on the boats, he knew that foreigners had this tradition for a long time, but there were no cats on the imperial ships or other warships of the navy, so he asked this question.

"This is what my subordinates should do!" Zhou Xiang smiled and said, but he thought about where to find a cat for His Highness. However, he sighed in his heart that it was not easy to fool His Highness, and he knew even such a small matter.

"What's going on in the trial production of the flowering bullet?" Zhao Bing asked as if he was looking at the busy craftsmen.

"Your Highness... something went wrong." When he heard Your Highness ask about this, he immediately became depressed and said with his head down.

"What happened? Has someone hurt?" Zhao Bing asked anxiously, seeing how much mistake he had made.

"No, no, it's all incompetent. After several batches of this flowering bullet were tested, it could not meet the requirements of Your Highness." Zhou Xiang waved his hands repeatedly. He knew that if there were casualties in the work, Your Highness would definitely be severely punished. If no one died, he could still discuss it.

"What's the problem?" Zhao Bing's voice eased a lot.

"Your Highness, one is about flowering shells. If this is done thin, it will break if it cannot penetrate the side of the ship when it is shot. If it is made thick, it can penetrate the sideboard. However, if it is filled with less medicine, the power will be smaller. There are too few broken shrapnel, which will not achieve the killing effect." Zhou Xiang said as he looked at His Highness's face.

"So, what else is there!" Zhao Bing urged when he saw that he was silent.

"Oh, there is also the fuse. The crossbow fires too fast, so it is easy to blow out the fuse; and then, after falling into the water, the fuse is immediately annihilated by water. Both situations will lead to an increase in duds. The craftsmen thought of many ways, thickening the fuse and installing bamboo tubes, and the effect is very poor. They have never thought of a solution, so they cannot produce it." Seeing that His Highness had no intention of fire, Zhou Xiang quickly said that he poured beans into the bamboo tube.

"Okay, let's go to the Gunpowder Shop right away and see what's going on!" Zhao Bing thought for a while and said. He was not sure about it now. Let's talk about it after he went to the scene to see it.

"Your Highness, wait a moment, I will go and prepare the car!" Zhou Xiang trotted...

To be honest, Zhao Bing was very anxious. Since Chen Yizhong left Chameng and never returned, he began to feel uneasy. Then Jiang Wanzai fell into the water and died. His Highness was frightened and sick. He moved to the island of Juzhou, which made him even more panicked. These things were moving along the original trajectory of history, and he still seemed unable to escape the fate arranged by God.

Whether it succeeds or not, Zhao Bing will resist. He has not successfully escaped several misfortunes and has also won this large foundation. He remembers that he was defeated in Yashan and was killed by Liu Xiufu on his back and jumped into the sea and died. So if he wins this battle, or even loses himself but breaks out, then he can't be spared from death!

Zhao Bing felt that he had to have a powerful weapon to save his life and the capital to escape. But he thought that it was unlikely that he would take a dragon boat after becoming the emperor, so he thought of the giant boat that captured Liu Shen. Originally, he was like using it as his own boat, and had already ordered the capital to be renovated. He hurriedly asked someone to draw a boat, and then partially transformed it according to his own idea, turning the giant boat into a sea fortress that cannot be damaged or destroyed. It can attack and retreat or defend, but it can still run if it is not possible.

As for the flowering bullet, during the Battle of Qizhou Ocean, Zhao Bing found that the solid bombs of the crossbow cannon could not cause fatal damage to the enemy ships, so he had the idea of ​​continuing to try the flowering bullets. At that time, he was worried that the flowering bullets would accidentally explode in the closed dragon ship, causing huge damage to the ship and people. On the giant boat, he placed the crossbow on the deck. Even if it was not shot out, it would not cause fatal damage to the ship. Therefore, while renovating the giant boat, it also made the Gunpowder House step up to develop the flowering bullets. He thought it was a very simple thing, but this was a mistake.

Zhao Bing went to the gunpowder workshop without rest, and even drank no saliva, so he asked the craftsmen who participated in the trial production to bring two shells first. He looked at it and found that the material was gray cast iron with high carbon content. This thing had high hardness, but poor toughness, and was easily broken after being subjected to force. The crossbow fired fast and had a great impact. If it was thin, it would crack before it could penetrate the gangway. Of course, it would not produce the expected effect. Therefore, it would be directly discharged from the plan without having to worry about the brain.

After picking up the thick shell, Zhao Bing looked at it only four or five millimeters. According to several craftsmen, after many tests, only this thickness can not only ensure that it can penetrate the three-inch thick slab and explode, but the effect is not satisfactory. So he asked the craftsmen to charge medicine, press the fuze, and do not need to fire with a crossbow, and ignite it directly. He had already figured out that if the shell could not be used, there was no need to consider whether the fuze could be used.

With a loud bang, the flowering bomb exploded. Zhao Bing ran over without waiting for the smoke to dissipate. He could see the shells in half without looking carefully. He picked them up and shook his head. The rate of fragmentation was too low, and the killing effect on personnel can be imagined. He could only rely on flames and shock waves generated by the explosion to injure the enemy. Only those who are lucky can be smashed by shrapnel.

"Try a few more!" Zhao Bing waved his hand and ordered the remaining few, but the result was almost the same. The most one was broken into five pieces.

‘Ding ding bell, ding ding bell…pop!’

"How did this break?" The experiment failed, and Zhao Bing had no good idea. He held a hammer and used several shells as drums. Suddenly, one shell was broken into several pieces. He knew how strong he had. It was impossible to break the cast iron shell. He looked up at his masterpiece and asked a few craftsmen who were at a loss.

"District... Your Highness, except for the problem when casting, the sand shape was not done well, leaving marks, so your Highness broke as soon as you knock it!" A craftsman picked up the broken shell and looked at it and said.

"Tao, it turns out to be a defective product... Take it to me to see!" Zhao Bing thought it would appear, but was told that it was a problem when casting, which disappointed him very much, but a flash of inspiration flashed in his mind.

"There is a way, then paper and pen!" Zhao Bing put the broken shells together and looked at them, slapped his head.

The craftsmen did not dare to be negligent and hurriedly found the four treasures of the study. Zhao Bing first drew a spherical one, thought about it and threw it away. Then he drew a cylindrical one, then drew a pointed one, and then drew a garlic one... He drew it and threw it away, and drew more than a dozen pictures in a row before picking out a spindle-shaped one and drawing a grid on it. Then he wrote a bunch of symbols that no one could understand, and finally marked it with the size. He handed it to Zhou Xiang who was still waiting on the side, and asked him to go to the iron workshop to open the furnace immediately and still cast it.

Although everyone couldn't understand why His Highness made the shell like this, it can be seen that he was full of confidence and had a successful experience in the past, so he went immediately. In fact, Zhao Bing thought of the grenade in his previous life from the broken mark of the residual product. When this thing was first released, people were worried about the low rate of fragmentation. Later, he thought that the problem was solved by carving marks on the shell case.

The planes have different grenades, and the flight distance must be long. They must not only ensure the strength of the piercing board, but also ensure the fragmentation rate, and must also be accurately shot. Therefore, Zhao Bing thought of all kinds of shells in his previous life, thinking that only by weighting the shell head can the direction of the shell flight and fall. The middle part will reserve marks when making sand shapes, so that they can win three goals at once. As for whether it can be done, it depends on the experimental results...

When Zhao Bing was not idle at this time, he asked the craftsman to bring the fuse, and it was obvious that it was made of cotton paper rolls of gunpowder that he had "cleared". No need to try it, let alone throwing it into the water, the tide spots could not be lit. He thought for a while, and if he could understand the impact fuse, he would not have to worry about it. But although that thing was simple, the current technical conditions were still difficult to make. At least the detonation medicine was a difficult time. Thinking about it, just use fire to directly point it in line with reality.

Looking back, modern fuses use fuses as fuses, which play a role in delaying or timing. But he only remembers that black gunpowder is wrapped with paper and tied tightly with cotton ropes on the outside. He should also use moisture-proof agents to prevent the gunpowder from being soaked in water and can burn in water. Zhao Bing followed this idea and thought about it. There are not many moisture-proof agents that can be used in this era. All he could think of is beeswax, resin and tung oil. Tung oil is the most common and cheap. There are also gunpowder shops now, and it is only used to soak oil paper as sealed medicine barrels.

Zhao Bing thought of it and made it. He asked people to find oil paper, dispersed gunpowder and hemp rope. In this era, cotton ropes were still luxury goods, and hemp ropes could only be replaced by hemp ropes. Several craftsmen followed the prince's instructions and put them on horseback. They wrapped the gunpowder into a medicine column with oil paper and wrapped them with hemp ropes layer by layer to make a fuse as thick as a finger. He looked at it almost the same as what he had seen in his previous life and ordered people to ignite it with fire to try it.

‘Sir…Puff!’ The ruler ignited the long fuse and sprayed blue smoke on the ground, sparks rolling and swaying, and finally squirted out a fire on the other end, extinguishing it.

"Your Highness, it's done!" several craftsmen said excitedly.

"I'm afraid it won't work." Zhao Bing shook his head. He found that the gunpowder in the center could not be completely wrapped tightly, and it turned into powder with a little force. This situation is definitely not good for actual combat. No one can be careful when it is in a tense state.

"Try it again!" Zhao Bing knew that this was due to the lack of adhesive, but he couldn't think of something that could be used, so he could only continue to experiment to see if he could find another solution. However, after trying several times in a row, he still couldn't solve the problem, and he was a little discouraged.

"Your Highness, can we try to wrap the leads in it?" asked a young craftsman carefully.

"Yes, I'm rewarding him with a hundred coins!" Zhao Bing listened and pondered for a moment, then patted his thigh and said excitedly. Wrapping the lead twice will solve the problem of losing the powder!

"Thank you... Thank you Your Highness!" The little craftsman was shocked and stayed there. The person next to him quickly pressed him to the ground to express his reward.

Everyone immediately tested this method. Sure enough, the powder was no longer dropped, and the wind would not be blown out during the test firing. However, some of them could burn to the end, while others would blind the fire, even if they were cut off from the same fuse. Although the effect was not good in the water, it also showed that the idea was correct. Zhao Bing took two paragraphs and compared it and found the problem. The nonsense was because there were gaps between the leads, which caused water to penetrate.
