"Teacher, be careful."

Chen Kui has been thinking about gunpowder now, and his laboratory is full of saltpeter and sulfur.

I wanted to match a previously recorded number and it was completed soon.

The two of them came to the unmanned open space together.

When I tried this ratio test for the first time, Chen Kui almost died.

He tried it several times later, and it was also very thrilling.

The ratio of saltpeter sulfur was also slightly adjusted, but the power also felt a little reduced.

Zhao Hui watched Chen Kui ignite the lead, then immediately hugged his head and hid to the side, hiding behind a stone.

Zhao Hui was indeed standing on the front, with most of his body hidden behind the stone, with only one head exposed to look at it, and it was quite a distance, which was more than ten feet away from the gunpowder lit by Chen Kui.

boom!

It's like a thunder explosion.

However, in Zhao Hui's ears, this thunderclap was far inferior to the bomb's explosion in his ears.

At best, it is a firecracker with louder sounds.

However, in this quiet Taihang Mountains, the sudden explosion still alarmed countless birds and beasts.

Even though these birds and beasts have heard of dozens of times in the past six months, they are still panicked.

Big birds flew up from the forest and hovered in the air, trying to find out what was making such a loud noise.

The beasts on the ground ran out as soon as possible.

Even if they have heard such a terrifying sound countless times, they are still afraid, and even the king of the mountains and forests are still afraid.

"Teacher, are you okay?"

Chen Kui showed his head from behind the stone.

During the previous experiment, he ignited the lead and ran towards the distance.

Originally, the explosion was weak, so he had enough time to run to the safe area.

But there were several times when it was too powerful and it hurt him.

Later, I learned my lesson, ignited the lead and turned around, and hid behind the huge rock.

"I'm fine."

Zhao Hui also walked over from behind a stone more than ten meters away.

Unlike Chen Kui who hid behind the stone and did not dare to show his head, Zhao Hui watched the scene of the gunpowder explosion with his own eyes.

The sound is quite loud, throwing it onto the city wall can scare the enemy.

But this lethality is still too low.

That is, people who are very close and have bad luck are just scratched by fragments.

However, Zhao Hui estimated that this power was also due to the small amount.

If Chen Kui doubles the amount of medicine, it will be even more powerful and will be enough to be used on the battlefield.

The most important thing now is to solve security problems.

No one dares to use gunpowder like this now. Before he could blow up the enemy, he would blow himself to death.

"Go back."

Zhao Hui walked closer and looked around the exploded ground, and then prepared to go back.

When the two returned to the laboratory, Chen Kui asked, "Teacher, but what else does it need to be improved?"

"If it's powerful, it should be enough at the moment. We will increase the weight test tomorrow." Zhao Hui said.

"Also, let's make this lead longer. The gunpowder that will be matched tomorrow will be completely sealed in the clay pot, leaving only one lead outside."

"Okay, I'll go and prepare now."

Although the gunpowder that Chen Kui made today was also contained in a clay pot, it was not completely sealed.

The explosive power under the seal is completely incomparable without sealing.

To increase the weight tomorrow, Zhao Hui seems to have seen the power of the explosion.

Tomorrow will be a shocking sound.

The birds on the tree might be stunned and fall from the tree.

In the evening, Zhao Hui returned to Heifeng Village and stayed with Zhang Xue and Zhao Xian.

His house in Heifeng Village is still there, and people come to clean it every day.

Although there are many fewer people in Heifeng Village now, the school in Heifeng Village has not been removed.

Although there are only a few dozen children attending classes here now.

But the teacher here is definitely the best.

Even Chen Kui and the others would occasionally come to Heifeng Village to do some interesting experiments for their children.

Although there are fewer students here, they can learn more than those students from Youzhou, Jizhou.

"What makes you so happy?"

When Zhang Xue saw Zhao Hui coming back, she kept having fun and was a little strange.

Even if Zhao Hui teases his son, he is not so happy.

Zhao Hui said: "Gunpowder can almost meet the requirements."

The problems I saw today are actually not very difficult to solve.

I was worried that before the enemy was blown up, I would blow my own people to death, just make the lead longer.

The clay pots are completely sealed and are closely guarded. Torches are prohibited from appearing around them, so there is no need to worry that they will explode suddenly.

Few people know about the development of gunpowder, but Zhao Hui and Zhang Xue had already mentioned it.

"That's what you said, something that makes a loud noise?" Zhang Xue said.

"Yes." Zhao Hui was in a good mood.

Once gunpowder comes out, even if Cao Cao and Liu Bei are heroes, even if they have millions of elite soldiers in their hands, they will not be able to compete with gunpowder.

Even the veterans in Zhao Hui's hands would collapse instantly if they encountered a gunpowder explosion.

Moreover, with gunpowder, even on the tall city wall, Zhao Hui would have no trouble of attacking.

As long as the pottery jar filled with gunpowder is smashed onto the city wall with a trencher, what army dares to defend on the city wall?

He doesn't have to worry at all now, and he will give Liu Bei and Cao Cao time to develop.

With gunpowder, he will promote fertilizers next year, and his strength will usher in another leap and improvement.

Zhao Hui teased his son while talking with Zhang Xue.

He lay on the bed, and with his head tilted, he could see the stars in the sky.

This kind of life is very comfortable.

Even though Zhao Hui gave many things to the people below, he didn't have many such comfortable days.

In Youzhou and Jizhou, even if they don’t ask anything, they still report everything to him every day.

Some don’t need him to make a decision, they just let him take a look, and some need him to make a decision, and then the people below will continue.

The son fell asleep on Zhao Hui.

Zhao Hui and Zhang Xue whispered for a while, and they fell asleep together.

The next day, Zhao Hui ate five eggs, plus ten thousand noodles.

Then after Zhao Yong and Zhang Xue also ate, they took the mother and son to Huang Turban Village together.

When he was sleeping yesterday, Zhang Xue said she wanted to see the power of the gunpowder explosion together.

When he arrived at the Yellow Turban Village, Chen Kui was already preparing.

Zhao Hui hugged Zhao Xuan and walked around more than a dozen laboratories in Huangteng Village, which also opened his eyes.

Although he can't understand anything.

A few people even took their little inventions to play with Zhao Xuan.

As Zhao Hui's son, he is spoiled by everyone here.

Zhao Yong doesn’t cry or make a fuss, which makes people like it very much.

However, it is also difficult for these Zhao Hui's students to make Zhao Xuan laugh.
