The main purpose is not to hurt people but to fix the role of gunpowder crossbow arrows, as long as the gunpowder arrows hit the wooden target, they can be nailed into the target, and then the fuse of the gunpowder burns out and the gunpowder explodes. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Since the gunpowder bolt can be filled three or four times more than ordinary bamboo grenades, and its power is much greater than that of bamboo grenades, if a gunpowder crossbow arrow can hit the side of an enemy ship, it is enough to blow a large hole in the side of the ship and easily sink a warship.

In the past, the Han army also tried to use catapults to fire gunpowder shells on warships, but this method had a low hit rate, and if it was used in landing operations, it would have a good effect, and the catapults could carry out indiscriminate attacks on targets on the shore, but if it was a water battle, the effect would be unsatisfactory. After all, the opponent's warship target is small, and if you want to hit the opponent with a trebuchet on a wide river, the probability is very small, and you can't even reach one-tenth of it.

Therefore, Liu Yin doesn't have to worry about the construction of the navy and the construction of the warship this time, and can leave it to Wang Jun to do. However, in the use of firearms, Liu Yin is painstaking, the most powerful weapon on the warship is artillery, the range is long, and the power is strong enough, if Liu Yin can create a kind of Hongyi artillery similar to that used by the British Empire, let alone defeat the Wu State, it is to sweep the world, it is not a problem.

But making artillery is a technical job, and it is indeed not easy to cast artillery under the current conditions, and Liu Yin can only retreat to the next best.

The accuracy of the catapult is not good, if it is equipped on a large scale on a warship, the efficiency is very low, just imagine that one out of ten or even ten shots miss, what is the point of such an attack effect?

Among the heavy weapons, only the bed crossbow has a high hit rate, and Liu Yin can only think of a way on the bed crossbow, and the previous bamboo grenade gave Liu Yin a lot of inspiration. This time, he personally designed the gunpowder crossbow arrow, which was also made of bamboo of medium length and thickness as the raw material, and after drying, the tip of the bamboo was filled with three times the amount of gunpowder of the bamboo grenade, and the arrow was mounted on the top after sealing.

The bed crossbow used is also special, much larger than the ordinary bed crossbow, and it requires at least four soldiers with strong arms and strength to pull it open, so that the bed crossbow designed can ensure that the gunpowder crossbow arrows can be projected at a distance of at least 100 paces.

In water warfare, ships are fast, and if there is not enough distance to carry out a long-range attack, the opposing ship will quickly rush up, forming a close-range dogfight, so that the gunpowder weapon will lose its due effect.

Liu Yin provided the design drawings, and all the other things were handed over to the gunpowder workshop to make. This batch of gunpowder crossbows was also produced in Jiangzhou, and after the production was completed, it was handed over to the navy for assembly.

Gunpowder crossbow due to the large size, the area is naturally large, in addition to large warships, small and medium-sized warships are really not equipped, so these gunpowder crossbows are equipped on the largest building ship of the navy, basically each building ship can be installed on the bow position of two gunpowder crossbows, in the left and right sides of the building ship, respectively, five gunpowder crossbows, that is, a building ship, can be equipped with twelve gunpowder crossbows, can carry out a 316-degree all-round attack.

In this water battle, the first to enter the battle was naturally the light warship, and through contact warfare, Wang Jun also saw the gap between the Han army and the Eastern Wu army. If the same Mengchong warship is used, the combat power of the Han navy is obviously inferior to that of the Eastern Wu navy, which is inseparable from the training level and actual combat experience of both sides.

But with a building ship equipped with gunpowder crossbows, Wang Jun was full of confidence, and he had every reason to believe that with these gunpowder crossbows, the Han army could easily achieve an overwhelming advantage.

As soon as the red flag of the Han army was unfurled, the formation of the fleet immediately changed, and the Mengchong ship group, which had been in the forefront, quickly retreated in the direction of the rear of both sides at this moment, and the building ship group that was originally in the rear was pressed on a large scale.

Yuan Jian was triumphant at the moment, in his eyes, the Han army sailors were just a group of recruits, whether it was the control of the warship or the use of tactics, they were still very naïve, and it was impossible for them to be the opponent of the Dongwu Navy at all, and the Dongwu Navy could easily crush them.

Watching the Han army's Mengchong ships retreat in embarrassment, a hint of mockery appeared on Yuan Jian's face, wanting to fight with Lao Tzu and practice for another three or five years.

After the Han army's Mengchong ship group retreated, the Lou ship group rushed up. Compared with the tall and mighty building ship, the long and low lonely Mengchong warship is like a three-year-old boy crashing into a giant man who is tall and tall, and it is not an order of magnitude in size.

However, Yuan Jian was still sneering, the Han people Paimon rushed to the ship and couldn't beat it, so they wanted to use the building ship to bully the small, which was simply a joke. Although the building ship is huge, it also has a considerable weakness, that is, the speed is slow, the maneuverability is poor, in Yuan Jian's view, these big guys have no other ability except for rampage, Mengchong battleship can rely on the characteristics of mobile and flexible ship speed, attack in a roundabout way, advance if you are profitable, retreat if you are unfavorable, and advance and retreat freely on the river, these large warships can't help it at all.

Seeing more than a dozen building ships of the Han army rushing up in a straight formation, Yuan Jian smiled, determined to play with them, and ordered the Meng Chong ship group of the Wu army to go head-on, pass through the middle of the Han army's building ship group, and after making an attack, then penetrate through the rear flank of the Han army's fleet and give them a disembowelment.

Yuan Jian still has a lot of confidence in this style of play, don't look at the Han army's building ships are so powerful, but the distance between the building ships is too far, and there are no small warships in the middle to protect them, so the Wu army's warships can easily intersperse in a roundabout way, and the Han army's ship formation will be scattered.

In Yuan Jian's opinion, the formation of the Han army and the navy army has no rules at all, and a group of landlubbers dare to come here to get an axe, and it is not good to teach them a lesson, I really don't know how many eyes Lord Ma has.

"Rush!" With a wave of Yuan Jian's commanding flag, dozens of Mengchong battleships rushed towards the Han army's group of ships like arrows from the string.

The building ships of the Han army still maintained an unhurried speed and sailed smoothly on the river.
