"Brother Decao said before that there was something looking for me, I don't know what?" After finalizing the matter of Zhuge Liang's brothers, Huang Chengyan remembered what Sima Hui said before, so he took the initiative to ask.

"Ahh Sima Hui slapped his forehead, thinking of this, he picked up the scroll of the catalogue he had seen before and came to Huang Chengyan and spread it out, "Brother Chengyan, have you heard of the battleship of the Yuan family?" ”

"Battleship?" Huang Chengyan's eyes lit up, and he hurriedly lowered his head to look at the catalog......

Huang Chengyan was almost the first to receive the news of Jiangdong's defeat, so he naturally knew the culprit who caused the defeat of the navy, but he only knew his name.

"This, isn't this a bed crossbow?" Looking at the catalogue on the case, Huang Chengyan looked up and asked in confusion.

Sima Hui nodded and said: "Yuan Jiazi's battleship is a long-range siege weapon installed on the ship, firing stone bullets and fire oil bombs, the Jingzhou Navy is trying to imitate to resist the enemy, but there is a problem that cannot be solved, in a hurry, I sent it to our academy for help, but unfortunately I am not good at this, I didn't understand it after watching it for a long time, so I thought of you, Brother Chengyan!" This matter is related to the local security of Jingzhou, and although I live here, I have to wait for it wholeheartedly. ”

"Oh!" Huang Chengyan was stunned, with a solemn look on his face, "Why can't you solve the problem?" ”

Sima Hui pointed to the catalogue and explained: "We have to install siege engines on the ship, only this crossbow is the most suitable, but only six can be placed on the warship, but ten siege engines are installed on the Yuan Jiazi battleship, so the difference in combat power between the two sides is too far."

However, this is not the main thing, the most important thing is that the opponent's siege engine is good at firing stone bullets and fire oil bombs, which has a great destructive power on the hull; The bed crossbow, on the other hand, is suitable for firing arrows, has a strong penetrating power, but has much less destructive power. Although it can also shoot stone bullets, it is no problem to hit big targets such as cities, but it is not good to move to a bumpy water to fight a moving ship, both in terms of range and accuracy, it is far from Yuan Jiazi's battleship, so even if it is imitated, it still can't beat the other party, so this problem must be solved. ”

Huang Chengyan is good at the study of organs, and after listening to Sima Hui's explanation, he probably understood the problem.

Hitting a stone bullet with a bed crossbow is like hitting marbles with a bow and arrow, and the ejection is either on the arm of the bow or on one's own hand. Because the bow arm and the bowstring are parallel, the projectile trajectory is also parallel, so that the bow arm will get in the way, block the trajectory, and cause self-injury.

The length of the arrow can be placed on the bow arm to avoid this problem, but marbles cannot.

Turning a bow into a crossbow and a bullet can ignore this problem for a while, but when the crossbow becomes a bed crossbow and the marbles become stone bullets, the problem is also magnified along with the diameter of the stone projectile, which is so large that it affects the key stats of the bed crossbow - range and hit.

To put it simply, the crossbow arm, the ball, and the crossbow string are too large in diameter to achieve three points and one line, which affects the accuracy; And because the crossbow arm is in the way, the bullet needs to be tilted upward, but the trajectory will not be tilted, so the friction between the stone bullet and the bullet increases, which affects the muzzle velocity and reduces the range.

If there are no problems, in fact, the bed crossbow has a longer range than the ballista, because the elastic force of the bed crossbow arm is greater than the torsion elasticity of the ballista. However, the construction principle of the ballista is similar to that of the slingshot, which is a professional stone projectile instrument, and there are no problems with bed crossbows, so Yuan Yao gave up the bed crossbow and chose the ballista.

But the ballista did not appear in the east, and the people of Jingzhou did not know about it, and they did not expect that there would be someone more powerful than them on the water before, and they were not ready to go to others to steal technology, and now they can't send spies.

As long as Yuan Yao takes the land south of the Yangtze River in Jiangxia County, then most of Jingzhou is within the combat radius of Yuan Yao's army, and it will be too late for Jingzhou to do anything.

Huang Chengyan studied it for a while and then raised his head and said, "This problem can't be solved at once, I'm afraid I'm going to bother Brother Decao here for a while." ”

"Stubborn!" Sima Hui stood up and bowed to Huang Chengyan and said, "Jingzhou's waterways are crisscrossed, if there is no naval army to protect it, it will be difficult for millions of people to live in peace, and this battleship is the most important thing." Hui is incompetent and can't solve this matter, so he can only ask Brother Chengyan! ”

Sima Hui only saw the safety of the people, but Huang Chengyan knew that this matter was also related to the life and death of their alliance of several major families, if Yuan Yao beat him to Jingzhou itself, then these families in power would be to blame, so he couldn't tolerate the slightest sloppiness, so he got up and solemnly returned the salute: "Brother Decao, rest assured, I am obligated to do so." ”

The two adults were asking each other, but they didn't notice that Huang Yueying, who was hiding behind Zhuge Liang, was pulling Zhuge Liang's sleeve to cover her lips, revealing a pair of bright big eyes, looking at the catalogue on the desk with great effort.

Seeing this, Zhuge Liang quietly dragged the catalogue to his side, so that Huang Yueying could see it more clearly......

The Jingzhou naval army almost poured out of Jiangdong this time, and only 30 or 50 ships were left on the mainland to patrol the river to maintain law and order and ensure the smooth flow of waterways.

There have been a lot of thieves these days.

When it was learned that the navy army had been wiped out, the whole of Jingzhou fell into a panic.

Without the escort of the navy, not to mention those water thieves who are usually rampant, Yuan Yao would not be indifferent just looking at Jingzhou, which was like being stripped naked. Even if he doesn't occupy the city, he will definitely land everywhere and plunder everywhere, and then Jingzhou will never be at peace.

Cai Mao and Kuai Yue did not continue to stay in Jiangnan, the ships were burned out, Kuai Yue's plan to change the ship became a fart, and it was useless as soon as it was released, so it was meaningless to stay in Jiangnan, and if they didn't go, they might not be able to go, so before the waterway was clear, the two handed over the remaining 20,000 soldiers to Wen Ping, and hurriedly returned to Jingzhou itself.

They need to return to Jingzhou to keep their rights, and the only way is to continue Kuaiyue's plan to change ships, so that others can believe that they can keep Yuan Yao out of their homeland, so that they can at least maintain their power for the time being.

No one dared to guarantee that the empty shell of the navy army at this time would still be able to stop Yuan Yao, and Cai Mao and Kuai Yue could at least come up with a way that could not be refuted.

The two never expected that they would have to rely on Yuan Yao's deterrence to protect themselves in the end, but this only treats the symptoms but not the root cause, and in the end, it depends on whether they can keep Jingzhou and ensure that everyone's interests will not be harmed, and the key is whether they can successfully transform the battleship.

If you have to have a ship to change the ship, it will definitely be too late to build it now, but even if the remaining dozens of ships of the navy are all changed, they can't stop the current Yuan Yao, so Cai Mao has set his sights on the water thieves, they are the only force in Jingzhou that can immediately take out a large number of warships.

In normal times, the Jingzhou Navy is too lazy to suppress thieves, because if the people's livelihood problems are not solved, the bandits are inexhaustible.

It is impossible for water thieves to have big guys like fighting ships and building ships, but the ship is their main warship, and what Cai Mao wants now is the ship. In addition, they are all working independently, and they are easy to buy or break each one, so it has become Cai Mao's best target and only goal.

And Kuai Yue's task is to transform the battleship, but he didn't expect that in his eyes, a battleship that is just a battleship with a siege engine would be so troublesome, and he couldn't complete it by his own ability, so there was the scene where Sima Hui begged Huang Chengyan before......
