Zhu Xiaobao has been studying his modern weapons for the past three months, of course, this modernization is relative to this era of cold weapons, and his things are the most backward in modern times.

Now his red-coated cannon is also made, but the weight is large enough, a barrel weighs four or five hundred catties, and it takes four strong men to lift it. Of course, Zhu Xiaobao also made a sturdy gun mount, and there were two wheels underneath, but later he found that this gun carriage was not very useful, because this thing did not need to be moved often, and was mainly fixed on the gun emplacements on the city wall.

Although this redcoat cannon is already very heavy, the strong recoil still needs to be readjusted after each fire to aim at the target again. Moreover, the loading speed is also very slow, and the barrel and charge port must be cleaned after each fire, mainly the residue left after the detonation of the fired gunpowder.

Now the barrel has six rifling, and the shell is streamlined, and the gunpowder at the charge is detonated to launch the shell with a huge thrust, and at the same time ignites the fuse on the warhead, waiting for the shell to fall to the target just in time to detonate. In fact, Zhu Xiaobao divided the current cannonball into two parts. Because Zhu Xiaobao can't make real shells, which cannot be produced and processed by small workshops, they need large-scale stamping equipment and cutting equipment, so they can only produce the most simple and practical shells.

However, the steel used to make the warhead has a considerable technical content, which is hard and brittle, which can ensure that it is blown to pieces after the explosion, and the fragments are also very sharp, which can maximize the lethality! The firing range and accuracy of this kind of artillery have been greatly improved compared with the original, and because of the rifling in the running tube, it can already reach a firing range of 1,500 meters.

This rifling was pulled out by Zhu Xiaobao himself, in order to pull out this rifling, he first made a set of broaches, just this set of broaches, he tested it for more than a month, and finally he was barely satisfied! In fact, there are many auxiliary equipment in the middle, which have been developed by Zhu Xiaobao in the same way.

His shotgun was now rifled in the barrel, and if the bullet was loaded, it would have been able to shoot very far, but it also needed to trigger the detonator chamber to get the bullet out, a bit like the earliest flintlock pistol. Because for the same reason, he still manages to produce shells and bullet shells, but Zhu Xiaobao is already preparing to get a small stamping equipment, and if the research can be successful, then the bullet shells can still be processed and produced. But this will be a long time before it happens!

Now Zhu Xiaobao wanted to go to the sea to watch the battle, so he thought of loading a few cannons that had been built on his colorful sailing boat. In fact, his artillery had already been fired in the Cave Heaven and Blessed Land, but it was a solid bullet and would not explode, because the place on the island was too small, and once it deviated from the target, it would cause a lot of casualties.

Moreover, during the test launch, only Duane Duwang and the old apprentices were present, and Wu Yue, Tong Wuxin and others were busy training the four thousand soldiers stationed on the island. Zhu Xiaobao also wanted to surprise them, but they didn't expect the opportunity to come so soon!

Wu Yue had never heard of the name 'naval gun', so she asked a little puzzled: "What naval gun?" What's the use? ”

"Well, it's almost like a bomb fired by a mecha tank, but it's much more advanced than that thing, and it shoots farther, so you don't have to throw it with your hands!" Zhu Xiaobao thought about it before he could barely explain it clearly. No one had ever seen this thing, so of course it would take a lot of effort to explain.

"Hey! Do you know how far a crossbow can shoot on a warship? How powerful is it? Hundreds of crossbow arrows were fired, and it was really terrifying! If it's a rocket, your ship will be full of fire in an instant, and a stick of incense can burn the whole ship! Tong Wuxin said a little anxiously at this time, she thought that Zhu Xiaobao was too simple.

Tong Wuxin is the daughter of the pirate Tong Jiao, who has seen a real naval battle, very tragic, once fighting, often a boatload of people are burned or shot, even if they jump into the sea, it is difficult to escape death. In naval warfare, fire attacks are the first choice, and at least half of the people are responsible for extinguishing fires.

"Hey, hey! As long as we're far enough, we can't be beaten, right? How far can a strong crossbow shoot on a warship? Zhu Xiaobao actually asked with a grin.

"I can shoot to a distance of two or three hundred paces, and no matter how far it goes, it won't be lethal, and the accuracy can't keep up!" Tong Wuxin said a little helplessly, it seems that this little treasure still doesn't give up, and still wants to go to sea.

"That's not over! Let's watch the battle five hundred paces away, wouldn't that be dangerous at all? Besides, I've lowered all the sails, and with my newly equipped driving propellers, we're much faster than those ships. Zhu Xiaobao was immediately relieved when he heard this. He smiled firmly. He must go to sea, and there is another purpose, which is to try the colorful sailboat he has just transformed, in fact, it can't be called a sailboat anymore, he doesn't even need a sail!

With the experience of the last mecha chariot, this time it is much more convenient, or through gear transmission to rotate the propeller at the bottom of the ship, in order to improve the speed of the colorful ship, Zhu Xiaobao made the blades of the propeller a little bigger, of course, the consequence of this is that it is very difficult to start, but Zhu Xiaobao has long thought of this, he deliberately set aside sixteen people to be responsible for shaking the force transmission rod, these sixteen people are all strong female guards, this kind of military secret can of course only use the person he trusts the most, so this time it is still headed by Wu Lijia, Responsible for the drive of the colorful boat. Of course, this kind of hard work must be indispensable to the great beauty!

It took half a day to load the eight red-coated cannons onto the colorful boat, and the sailor's paddle position was just to place these six guns, but there were only four guns on one side, which was a bit less. According to Zhu Xiaobao's idea, eight guns should be installed on each side of the hull, and if it was a real warship, it would be even more!

This kind of naval cannon is much smaller than the caliber of the red-coated cannon, mainly for the convenience of installation and disassembly, and when installed on the ship, it does not need such a bulky cannon, as long as the range is enough, this kind of cannon is specially prepared by Zhu Xiaobao for warships, the length is one meter five, the weight is two hundred catties, two people can lift it.

Zhu Xiaobao's colorful ship is actually only twenty meters long, which is too small compared to those warships, those warships generally have a length of about 100 meters, and they are two floors, and the flagship of the Seven Princesses is even more than three floors, with a length of one hundred and fifty meters. It can accommodate thousands of people. You can run horses on it.

When it is installed, Zhu Xiaobao looks at it, and he can also install these eight cannons, because the width of the hull is limited, and the eight cannons must be staggered, so these eight cannons already occupy half of the hull, and the back section is the sixteen female soldiers who are responsible for driving, so the remaining space is not rich. At this time, Zhu Xiaobao understood why the warship was made into a double-decker, because it could have more space and more combat power. It is also possible to install more weapons and equipment.

When everything was ready, the ship turned out to be a little bit of a shape, with two powerful crossbows in the bow, and a range of one hundred and fifty paces. In addition, plus Wu Yue and Tong Wuxin, as well as the old apprentice and others, there are a total of thirty-six people. Among them, Duane Duwang also came, because of the control of these eight cannons, now only they can, and even the old apprentice will also, and now the old apprentice is really learning a lot from Zhu Xiaobao.

"This is what you call naval guns? How far can you hit? In case we run into an enemy, it's not a joke, it's so far away, even the people of the Seventh Princess won't recognize us, and they will still attack us when the time comes! Tong Wuxin still asked uneasily.

"Hey, hey! Her strong crossbow can shoot up to 300 paces, and my naval guns can shoot up to 1,000 paces, who do you say is more powerful? I'd really like to find an opponent to try the power of this naval gun! Zhu Xiaobao said with a little expectation, the shell tested on the island is a solid warhead, that is, the range is counted, because the shot is too far, there is no way to test shoot a warhead that can really explode on the island, so until now Zhu Xiaobao does not know what the power of this cannon is! Another main purpose of going to sea this time is to test the power of naval artillery again. Of course, it's not aimed at the Seven Princesses, but I want to find a target in a place where no one is there and shoot a few shots!

"So far? You're talking nonsense, aren't you? Tong Wuxin immediately exclaimed, even Wu Yue next to him didn't believe it, only the old apprentice nodded vigorously, he had seen it, although it didn't explode, but it had already shocked him very much! He had the same expression at first.

"Do you want to talk to the princess?" Wu Yue still asked habitually, and then regretted it a little, the most annoying thing for Zhu Xiaobao is that you have to ask for instructions from the nineteenth princess, don't be Wu Yue, you have already developed a habit.

"I'm not going to do anything bad, there's nothing to report, you go and talk to the princess, she won't let me out!" Zhu Xiaobao said very unhappily.

"Master, shall we go? I've got everything with me! At this time, the old apprentice said excitedly, his identity is really very special, no one dares to ask him, but he listens to Zhu Xiaobao.

"Good! Get on the boat, if you don't feel at ease, you can not get on the boat! Zhu Xiaobao deliberately shouted loudly.

Tong Wuxin and Wu Yue looked at each other, so they had to bring their weapons and follow the boat. The other female guards were not worried at all, and excitedly got on the boat to look left and right, this boat is so special, they all know Zhu Xiaobao's ability, so they are all looking forward to seeing any surprises again!

Briefly talking to Wu Lijia, the sixteen female guards began to shake the transmission rod, this colorful boat started very quickly, much faster than Zhu Xiaobao imagined, and when it started, Tong Wuxin had already begun to be secretly surprised, the speed of this boat was faster than any boat she had ever seen, and Wu Lijia and they were still laughing loudly, as if they had not fully exerted their strength. Because Jumei has not yet sat in the position of shaking the transmission rod, she is fiddling with her golden stone bow, she brought five pots of arrows this time, a hundred special iron arrows, so I really want to be able to perform this time, I have practiced for so long, and I haven't really played yet!

Twenty female guards, taking turns shaking the transmission rod, this speed is also very fast, driving in the east-west direction for two hours, and finally approaching Lingyue Island......
