The army began to change its outfits, but Chi Nan was once again lost in thought.

"My lord, what are you still thinking? With such a powerful pea cannon, we are rampant enough in Remas. ”

Chi Nan rolled his eyelids: "What is rampant enough, do you think this pea cannon is so powerful." There won't be a large number of black iron-level berserkers coming, otherwise they won't be used at all. There are also Beast Dogs, which we don't have very many here. If there are a large number of them, they can completely bite a few people to death against the attack. ”

"It's unlikely, what the hell are you worried about, isn't there still a big army on the front. ”

Chi Nan sighed: "We can't think about relying on others for everything, we need our own strength. But this pea cannon has almost been improved to the limit. Normal attack, which is close to the normal attack of the Black Iron Warrior. ”

"If you want to continue to increase your attack, the best way is to increase the bullets of the pea cannon, but after you increase it, the weight will increase, and the firing power will become smaller, or the pea cannon is not big enough. ”

"Then why doesn't the lord increase the size of the pea cannon? "This soldier is strange.

Shi Nan groaned: "Increase the size of the pea cannon, then the absorption of air will increase, and the recoil will also increase, your physique will not be able to bear it at all, and it is easy to hurt yourself." ”

The soldier didn't care: "Isn't it just that the physique is not enough, we just can't lie on the ground and fight." If it really doesn't work, find someone to come behind us, two people together. ”

Chi Nan's eyes suddenly lit up: "Wait, what did you just say, let's talk about it again." ”

"Find someone to cushion in the back, two people together?" the soldier was a little surprised.

"It's not this sentence, it's the above sentence. Chi Nan was already a little excited at this time.

The soldier thought about it for a moment and hurriedly said, "What I said was, we were lying on the ground?"

Chi Nan slapped his hands fiercely: "That's right, that's it, you can put it on the ground, I didn't think of it." I've been thinking about individual weapons, this is war, how can war be done without artillery. ”

Chi Nan said happily: "Very good, I will write down a great merit for you when I go back, and when one leg comes back, I will let you be promoted to captain." In Chinan's view, the talent of the mind type is the most important.

The soldier was a little confused, why was his lord so happy, didn't he just say a word. Although the lord of his own family is usually approachable and anyone can talk to him, no one dares to be disrespectful. The soldier was a little confused, but he didn't dare to ask anything, and now the lord was obviously happy.

Being able to call out the nickname of Lord Holm in front of him on one leg can imagine the mood of the lord. The nickname of One Leg was known to all the soldiers, but no one dared to call it because of the respect for Holm.

In the entire territory, there are only a few people who can call Holm like that.

Chi Nan once again entered the experimental state, and after the third generation of the pea cannon was manufactured, Chi Nan began to make more special pea cannons. This is a very large one. An ordinary pea cannon is only the thickness of an arm, and the bullet inside is only as thick as a thumb, which is not very large, just a single weapon.

But this time, what was transformed by Chi Nan was a very thick cannon barrel. This cannon barrel is even thicker than himself, and the ammunition in it has also been made bigger than a human head by Chi Nan.

It's just a small bean in the middle, and all around it is densely wound with fibers, and it's just a big piece of wood.

The barrel of this cannon is placed on the ground, and there are three awls in the back that look like the awls under the pea cannon, which are three fibrous roots, which can be inserted into the ground to keep growing. "It's a pity that it's so big that only two shells can be dropped. Forget it, test it first, and improve it after success. Kinan aimed the barrel of the cannon at a hill in the distance.

There was a rope behind him, and when Chi Nan pulled it hard, the gas in the barrel suddenly burst out. With a "bang", a black shadow shot out in an instant. The shell flew more than 500 meters and hit a hill in the distance.

Then, the hill in the distance was so dusty that it was impossible to see anything clearly. "Let's go, come with me. ”

Chi Nan didn't care about the others, and ran over there. The soldiers around him hurriedly followed, carefully guarding the surroundings. It didn't take long for Chi Nan to run all the way to this place.

Where the hill was hit by shells, a large crater of more than two meters appeared. The shell was in the middle of the crater, and the surface had been damaged a lot. You know, it's a hill.

Although it is not a pure stone mountain, there are also a lot of stones. To be able to cause such a large crater, the impact force can be imagined. "Oh my God, my lord, what the hell have you made here? ”

Chi Nan looked proud: "This is an improved type of pea cannon, I don't think it should be called a pea cannon, it should be called a pneumatic cannon instead." This thing is used to attack the city wall, and the effect is definitely not weak. ”

In contrast, the Nanmu city wall made by himself will leave a big gap if it is hit by this pneumatic cannon. The continuous attacks will definitely destroy the Nanmu city wall. If this were replaced by a wall of ordinary nobles, it would definitely be easier to destroy. "The shell was not too badly damaged, which means that the strength of the shell exceeded the attack power too much. ”

"In this case, it might be better to replace it with a hard-shell shell instead of using this fiber shell. ”

Thinking of this, Chi Nan didn't pay attention to those soldiers, but walked back to his previous position by himself. The soldiers next to him didn't dare to take it lightly, and they had been carefully protecting the surroundings of Chi Nan.

It's just that just as Chi Nan was about to return to the test site, there was a "bang" and an explosion occurred in front of him. Chi Nan looked at the front blankly. "Damn, how could this be. Chi Nan was surprised to find that the pneumatic cannon he had just made actually exploded. The location of the explosion was the air compression compartment in the back, where the shells did not come out.

Because of the explosion of the air, the shell fell out of the barrel of the pneumatic cannon and slowly rolled in front of him.

"What the hell went wrong. Chi Nan hurriedly ran over and studied his feelings seriously. I can only feel the ability of the plant itself, but I can't feel the other effects of some instincts.

However, Chi Nan soon found the reason, and the reason was that the compressed air chamber was too weak. "The pea cannon is very difficult to break because the barrel ratio is much thicker than this. And in terms of compressed air, the pneumatic gun compresses more. Therefore, the pressure of the air is greater, and the damage to its own cabin is more serious.
