His expression obviously told Chen Yuan that Chen Yuan's guess was completely correct! Why does Lao Lu want to be a good colt? What can a colt do him a lot of help in the court struggle?

Fan Zhongyan's methods of struggle for those gentlemen are very regular, and the harem is almost a forbidden place for them. Those gentlemen will not drag the fight into the harem, let alone involve the people in the harem.

Lu Yijian really didn't want to fight with Fan Zhongyan, because even if he kicked Fan Zhongyan out of Bianjing like the last time before, the scene of a hundred officials sending each other would still sting Lu Yijian's heart. Therefore, Lu Yijian's knife is aimed at Pang Ji!

Chen Yuan understood, this time Pang Ji put Lao Lu together, and Lao Lu was very angry! The consequences are severe! This old guy is so vicious! Chen Yuan believed that when he was preparing a knife for Pang Ji, he would definitely beg in front of Pang Ji: "Brother, you can pull my brother!" ”

When Pang Ji used all his strength to pull him up, he would stab Pang Ji in the heart!

Definitely heart-to-heart! Once Lu Yijian is ready to turn his face with Pang Ji, he will not give Lao Pang a chance!

He can understand Lu Yijian, a partner like Pang Ji, if one day he starts to use you as a pawn, then your best choice is to strike first and kill him! It's just that Chen Yuan didn't expect that Lu Yijian would actually choose to knife Pang Ji when he seems to be the weakest and needs Pang Ji's help the most!

Early the next morning, Chen Zhusi came to his post very early. Although his funds are not yet fully in place, Zeng Gongliang's words are indeed much better than before. When Chen Yuan came, Zeng Gongliang was arguing with a man named Ding Du about something.

The argument between the two people had obviously entered a white heat, and Zeng Gongliang saw Chen Yuan pull him over: "Chen Zhusi, you can tell me, I said that when defending the city, put the stone cannon at the head of the city, so that you can see the enemy attacking." This guy said it would be better to put the cannon in the city. ”

There are a lot of priests in this workshop, but Chen Yuan is the only one who can be on an equal footing with all the adults.

"We've been putting trebuchets at the head of the city, and that's because we've been doing it wrong!" Look at how many trebuchets our border cities of the Great Song Dynasty lose every year? ”

Zeng Gongliang shook his head: "It's normal for the trebuchet to be broken, we can start from the structure to make the cannon body stronger." The lethality of the stone projectile is very large, and it is not advisable to put it below to shorten the attack distance! ”

Ding Du retorted: "I don't understand, why we put the cannon under the city and wrap it with something, so that we can not only defend the city, but also defend the artillery, isn't it better?" ”

Chen Yuan hurriedly waved his hand and asked, "Two adults, listen to what you mean, the shells of this stone cannon have been studied?" ”

Zeng Gong nodded: "Lord Ding found a stonemason in the quarry last night, that stonemason once used gunpowder to blow up a boulder, we used a small stone to experiment this morning, and the effect is good!" ”

Chen Yuan was very pleasantly surprised! He knew that the birth of this stone bullet meant that an era of hot weapons in the war began to sprout. Historically, due to the lack of attention of the Song Dynasty, or the deliberate suppression of some people, this small sprout was not able to blossom and bear fruit.

Now that I'm here, of course this won't happen! However, Chen Yuan really didn't know whether this cannon was placed under the city or on the city: "Two adults, do you think this is good, the people of the Yang family will come soon, they have been on the battlefield, whether it is attacking or defending the city, they know more than we know." Let them say whether it is appropriate to put down the city or put it on the city. ”

Ding Du and Zeng Gongliang nodded at the same time after hearing this. This question may seem like a small one, but it directly determines the shape of the cannon. The cannon placed at the head of the city is limited by the city wall and cannot be too large, while the cannon placed under the city requires a strong "recoil", and the shooting of the cannon body must pursue a force.

Lu Yijian gave the word "Wuwei" to Chen Yuan yesterday.

The so-called inaction does not mean that you do nothing, but that you know what you should and cannot do. Only when you know what you can't do on your own can you do what you have to do.

To some extent, this is the same concept that Chen Yuan insisted on at the beginning. He didn't want to fall too deep in the court, and he didn't want to be a general. Because he knows he's not good at doing this kind of thing.

Just like now, whether the cannon should be placed at the head of the city or under the city, Chen Yuan thought that it should be up to those who had been on the battlefield.

Tianbo Mansion is obviously very supportive of Zeng Gongliang and others' research this time. Not only did he send fifty personal soldiers, but he also led the team by Yang Paifeng himself.

This is the second time Chen Yuan has seen Yang Paifeng, the legendary "fire girl" in Chinese history, who seems to be more like a general than Mu Guiying.

Mu Guiying is very calm, and her calmness makes people feel a little incomprehensible. But Yang Paifeng has a posture that a general should have!

She walks, talks, does things, and is clean and neat!

"Guns under the city? Can you hit the enemy? If you can hit it, it's best to put it under the city! Yang Paifeng replied very simply, and Ding Du showed a smug smile on his face after hearing this: "Huo Shuai, rest assured, our stone cannon is also fired in a curve, which can bypass the city wall and attack the enemy who has entered the city edge for a hundred steps!" ”

After hearing this, Zeng Gongliang said: "Huo Shuai, if we put it at the head of the city, we can attack the invading enemy who is hundreds of paces away, so if we give up more than half of the attack distance in vain, will it be too much of a loss?" ”

Yang Paifeng shook his head: "No, on the battlefield, the most effective distance to kill and injure the enemy is the place under the city." Far away, the enemy can dodge. ”

Zeng Gongliang didn't say anything: "Okay, just according to Lord Ding's will, when we build the cannon, we will build it according to Lord Ding's will." ”

Yang Paifeng was very interested in the newly made "stone bullet" that Zeng Gongliang said, and asked at the moment: "Lord Zeng, do you still have that stone bullet?" Can you show me? ”

Zeng Gong nodded: "There are still a few that didn't run out yesterday, I'll take Huo Shuai there." In addition, we have some new weapons, and I hope Huo Shuai can give me some guidance. ”

Zeng Gongliang first took Yang Paifeng to the spear workshop and took out the hook and sickle he made: "Huo Shuai, look at this gun!" ”

Yang Paifeng took it and shook it in his hand: "Yes, this is much more effective against the cavalry of the Liao State than ordinary spears!" It would be better if the adults made this gun lighter. ”

Zeng Gongliang was very stunned: "This, I made it according to our sergeant's ordinary spear, I made it and weighed it, it was generally heavy." ”

Yang Paifeng smiled: "You added a horizontal hook on your head, you must know that when you wave it, the weight of one pound on your head is enough to cover the weight of ten pounds behind!" If you don't notice it with a horizontal slash, but when you need to block it, the soldiers will find that the gun is heavy. ”

As soon as this truth was said, Zeng Gongliang immediately understood! He immediately looked at Chen Yuan and smiled: "It seems that there is really nothing wrong with inviting Huo Shuai over, if we do it behind closed doors, this gun will definitely be like this." Huo Shuai don't worry, I'll change it right away. ”

Chen Yuan suddenly thought that people like Zeng Gongliang should not be placed in the workshop, but should be put in a special research room, equipped with talents in various professional aspects, to create better conditions for him, so that he can play to his heart's content!

Everyone came to a clearing, this was also the first time Chen Yuan had seen the so-called stone bullet, looking at the stone in Ding Du's hand that was not too round, Chen Yuan knew that this was the cannonball, and even the ancestor of the missile!

The stonemason's method is actually very simple, he first smashed a crack around the stone with a small hammer, and then chiseled a notch out to put a large cannon into it! The last step is to wrap the notch again with a tin sheet.

The experiment was carried out in a square wooden barrel, which was very thick, and the walls of the barrel were four or five centimeters long. A craftsman put the stone into the wooden barrel and looked at Zeng Gongliang: "My lord, can you start?" ”

Zeng Gongliang stepped back a little: "Let's start!" ”

As the craftsman lit the fuse, soon a loud noise reached everyone's ears, even if Chen Yuan had been prepared, he was startled by this sound!

Yang Paifeng was very excited when he heard such a voice! Without waiting for Zeng Gongliang to greet him, he jumped up with an arrow step, looking at the traces of the explosion in the barrel.

The stone had been divided into five or six pieces, irregularly embedded in the thick wood, and deep cracks could be seen next to each stone, and you can imagine how powerful it was at the moment of explosion!

Yang Paifeng's hand touched those cracks, and he couldn't help but smile on his face: "Okay!" Good! Very good! ”

Chen Yuan also thinks it's very good, but it's not quite satisfying him! It would be nice to be able to penetrate the plank! Such a thick plank is about the same thickness as the ship's plank, if it can penetrate it, and get a few for Hu Yanqing, then doesn't his fleet want to grab which one to grab on the sea in this era?

Thinking of this, Chen Yuan immediately said: "My lord, I have an idea, if these stones are replaced with iron blocks, can they be more powerful?" ”

As soon as he finished speaking, Zeng Gongliang was stunned for a moment, and Ding Du was instantly shocked.

Chen Yuan thought he hadn't explained: "I mean, if it is replaced with iron, we can artificially create some cracks when we build it." Wouldn't it be much better to artificially keep some gaps than to stuff a cannon battle? ”

This method was only remembered after Zeng Gongliang's death, and at that time, the "iron thistle" made like the current grenade played a great role in the first Bianjing defense war.

Zeng Gongliang and Ding Du can be said to be experts in weapons, they have talent, but it is a pity that the two of them have been worrying about research funds all their lives, if it were not for Chen Shimei, the master of the horse, Zeng Gongliang and Ding Du and dozens of other weapons experts, it took five years to write "The General Essentials of the Martial Arts", and they only completed a few simple works in their lives.

Even the stone cannonballs that Chen Yuan sees now are more than ten years later. Now Zeng Gongliang didn't have the idea of using iron to make cannonballs in his mind, Chen Yuan said this, Zeng Gongliang immediately nodded: "It's feasible!" I think it's totally doable! Since the stone can be exploded, as long as the amount of medicine inside is sufficient, the iron and stone will explode! ”

Ding Du said: "I also think I can try it, but this is not as good as a stone, and it may cost a lot of money in the middle." ”
