The pot is on a reddish stove.

Although the flames did not jump, the temperature of the pot rose quickly.

I didn't know that the craftsman who was strong at gunpowder was stirring up there.

Cao Shuo and Mi Heng stood aside and spoke.

While they were talking about the catapult renovation, there was a sudden loud noise on the stove.

Not only were a few craftsmen and Mi Heng next to him startled, but even Cao Shuo was stunned by the loud noise.

Turning his head to look over, fortunately, the pot was open, and the explosion of gunpowder did not cause much damage, but the craftsman who stir-fried was looking at the pot that had been blown up with a dark face.

"What's going on?" Cao Shuo ran over and asked.

"I don't know." The craftsman was shocked and said, "It's stir-frying, and all the things in the pot are gone......

"If it blows up, of course it's gone." Cao Shuo said: "As I said earlier, as long as the water vapor is fried and the gunpowder turns black, you can also remove the pot from the stove. ”

Several craftsmen lowered their heads, and all of them still had panicked expressions on their faces.

"Childe, this is ......" Mi Heng, who also didn't understand the characteristics of gunpowder, looked at Cao Shuo blankly.

"You know how powerful the fire is, right?" Cao Shuo asked Mi Heng and the craftsmen.

Everyone nodded.

"The flame is so strong that it can burn people to charcoal." Cao Shuo said: "What I can tell you is that the gunpowder exploded, and the temperature was much higher than that of gunpowder. Maybe you don't think this pot of gunpowder is very damaging, but once you wrap them up, the explosion will be wrapped in something and spray out, and its power will increase several times, causing damage that you can't even imagine. ”

Mi Heng and the craftsmen looked at Cao Shuo with confused faces one by one.

They had never been exposed to gunpowder, and of course they couldn't understand the theories Cao Shuo said.

"Forget it." Seeing that they couldn't understand, Cao Shuo waved his hand: "If you don't understand, you don't have to think about it, and when you really see it, you will understand." ”

He then instructed the craftsman: "Stir-fry another pot according to the previous ratio." ”

Cao Shuo did not blame, and the craftsmen hurriedly prepared the raw materials according to the previous ratio.

This time, the stir-fry craftsman was no longer as absent-minded as he was just now.

Cao Shuo and Mi Heng also watched from the sidelines.

After a while, when the powder in the pot turned completely black, the craftsman looked at Cao Shuo.

"It's time to get started." Cao Shuo nodded.

After receiving the order, the craftsmen hurriedly brought the pot open.

"Go get some linen and Caihou paper." Cao Shuo commanded again.

Immediately, craftsmen rushed away.

After a while, the craftsman ran back with a piece of linen cloth and a roll of Caihou paper in his hand.

"Spread out the Caihou paper and sprinkle some gunpowder." Cao Shuo said: "The rest of the gunpowder is wrapped in linen, remember to wrap it tightly, and the gunpowder rolled up by Caihou paper is connected to it. ”

Although they looked confused, the craftsmen still did as Cao Shuo instructed.

Mi Heng asked Cao Shuo, "Childe, what is this going to do?" ”

"I know how gunpowder is made, and I know how to make it most effective." Cao Shuo said: "The explosion of gunpowder has a huge amount of energy, wrapping the energy, once it is ignited, it will erupt suddenly, which is completely different from the effect just now. ”

Although he still didn't understand the meaning of Cao Shuo's words, Mi Heng didn't ask any more.

Actually, he didn't need to ask too much.

As long as he made things according to Cao Shuo's method, he would understand after seeing the effect.

According to Cao Shuo's instructions, the craftsmen first unfolded the Caihou paper, sprinkled gunpowder evenly in it, and then poured a full pot of gunpowder on the linen cloth and tied the linen cloth tightly.

After doing this, the craftsmen looked at Cao Shuo.

Stay farther away, and bring the fire.

Cao Shuo commanded.

Immediately, a craftsman went to light a torch and handed it to Cao Shuo.

Holding a torch and instructing everyone to stay away, Cao Shuo lit a fuse made of Cai Hou paper.

It may be that there was too much gunpowder in the fuse, and Cao Shuo ignited it, and it burned to the end with a snort.

Immediately after that, a loud bang shook everyone's ears for a long time.

Holding a torch, Cao Shuo was confused.

Luckily, the fuse was long enough, otherwise he wouldn't have even had time to run.

Mi Heng hurriedly ran to his side, bowed down and asked, "How is Childe?" ”

Deng Zhan and Zhu Ao, who followed Cao Shuo here, were not lightly frightened.

The two of them ran to him, and did not bother to salute, but checked him from head to toe to make sure that there was no damage, and then breathed a sigh of relief.

"See?" Cao Shuo said to everyone: "These things are called explosive packets, if they are projected into the city, what will happen, I don't need to say, you should all understand." ”

"But it's blowing up too fast...... Mi Heng said, "Before we can react, it's already blown up, how can we project it with a catapult?" ”

"There are many uses for explosives." Cao Shuo said: "As for how to use it, after understanding his characteristics, you can study it carefully." With this kind of thing, we will be invincible in the future. ”

"Childe is that ......" Mi Heng asked uncertainly, "In addition to making this explosive pack, you can also make other things?" ”

The structure of the firearm is too complicated, even if Cao Shuo said it, Mi Heng and the others would not be able to understand it.

Cao Shuo knew very well that gunpowder had only been made, and there was still a long way to go in the development of new ordnance.

Rather than proposing to make firearms now, it would be better to wait for the craftsmen to familiarize themselves with the properties of gunpowder and then let them develop it further.

"Of course you can make something else." Cao Shuo grinned and said to Mi Heng: "But now you don't have to think about this, just familiarize yourself with the habits of gunpowder, and then develop a new gunpowder formula, as for what can be made with them, you can only slowly explore it later." ”

Cao Shuo refused to say more, and Mi Heng knew that he couldn't ask anything if he asked.

He instructed the craftsmen: "Think about how you can make the fuse burn more slowly." ”

One of the craftsmen replied, "It may have been too much gunpowder just now......

"Then put less." Mi Heng said: "I don't believe yet, I can't make a suitable fuse. ”

The craftsmen bowed their heads and answered, and once again took out the iron pot and put it on the stove, and prepared new ingredients.

It didn't take much time to fry the gunpowder, and after a while, the craftsmen fried the gunpowder.

They spread Cai Hou paper on the ground and carefully smeared the gunpowder on the paper.

This time they smeared it very thinly, with only sparkling gunpowder on the paper.

"The fuse alone is enough for you to study for a long time." Looking at the craftsmen who were busy working, Cao Shuo said to Mi Heng: "We haven't been fighting these days, but I hope that the next time you go out, you can provide enough explosives to the army." ”

"Childe, don't worry, we will definitely develop a suitable explosive package." Miyo replied.
