As Zhu Biao's words fell, a roar resounded through the heavens and the earth.

At the same time as the explosion sounded, countless shrapnel flew in all directions.

The shrapnel slammed into the armor on the target's body, sending sparks in the smoke.

And the shock wave brought by the explosion made Zhu Yuanzhang and others, who were more than ten feet away, feel a slight tremor on the ground.

When the smoke cleared, the guards cautiously approached the target.

He began to carefully examine the damage caused to the targets by the grenade explosion.

While the guards were checking, Zhu Biao also slowly put down the telescope in his hand.

"This power looks good, and the killing range is also very large, if this thing is really carried by light cavalry, even if it is not used to attack the battle formation head-on, it can be used simply for flank attack, it can also bring huge casualties to the enemy!"

"No, it might be better if you let a group of people use this object to intercept it while you are being pursued by the enemy! Especially for the war horses of the cavalry. Humans can wear protective gear, but War Horses don't have protective gear. ”

Although Zhu Biao is a learned Confucianism and Taoism, as the heir of Zhu Yuanzhang, the emperor immediately, how can he not know anything about the art of war.

Through the telescope given by Chu Ze, Zhu Biao witnessed the moment when the grenade exploded just now almost the whole way.

The flying shrapnel was so fast that he couldn't see it clearly.

But he could see the deep potholes in the wooden targets.

This grenade has a very lethal power.

Whether it is worn by cavalry or used when defending a city.

It should all be very powerful.

When Zhu Biao was still lamenting the power of the grenade, he didn't notice that his father had come to his side at this time.

And, his eyes stared straight at the telescope in Zhu Biao's hand.

His eyes were full of curiosity.

"Biao'er, what is this thing in your hand? Bamboo tubes for fires? ”

After hearing Zhu Yuanzhang's voice that suddenly sounded in his ears, Zhu Biaoren was directly startled.

After coming back to his senses, Zhu Biao's face couldn't help but rise with a trace of complaint.

"Father.. Why didn't you say hello first? I almost scared my son to death! ”

Faced with his son's complaints, Zhu Yuanzhang stood directly in place.

Wasn't he just saying hello?

And looking at Zhu Yuanzhang, who was a little unresponsive for a while, Zhu Biao realized what he had just said...

After reacting, Zhu Biao hurriedly saluted Zhu Yuanzhang.

He said in a somewhat apprehensive tone.

"Father's forgiveness, the son was too distracted just now, he didn't react for a while, and he collided with his father"

"Oh, oh, what do you forgive! It's just a little thing, we didn't say hello in advance just now, so I don't blame you. Not scared, right? ”

Although after being complained by Zhu Biao suddenly, he was a little stunned.

But after hearing Zhu Biao's apology, Lao Zhu didn't care whose fault it was, anyway, he just agreed.

After reaching out to help Zhu Biao, who was saluting and making amends, Zhu Yuanzhang's eyes fell on the telescope in his son's hand again.

Just now, everyone thought that the grenade of this second experiment would not have exploded.

Zhu Biao took the lead in reminding everyone.

It's as if he can see the whole thing.

This naturally attracted Zhu Yuanzhang's attention.

While the guards went to check the damage and safety of the target.

He stopped by to have a look.

Anyway, it's just two steps.

"Father, this is the telescope that Chu Zegang gave to his son, this thing is mysterious. It looks like it's just a bamboo tube, but if it's placed in front of you, you can directly see it dozens of feet away. ”

"Just now, Erchen relied on this thing and saw that the lead of the grenade was burned out little by little."

"Please also ask my father to take a look!"

After looking at his father's eyes full of curiosity, but he didn't know how to speak.

Only then did Zhu Biao react, his father wanted to see the telescope in his hand.

After understanding, he sensibly handed over the telescope in his hand.

"Hey, this is something that Chu Ze gave you, how can my father ask for it!"

After listening to Zhu Biao's introduction just now, Lao Zhu said that it was impossible not to want to see it.

A cylinder, put it on the eye, you can see something dozens of feet away.

And listening to the meaning of Zhu Biao's words, he should be able to see it very clearly.

Such a magical and fun rare thing, he really hasn't seen it before

But well, after all, it's a son's thing, how embarrassed is he to be Lao Tzu.

As for taking it and taking a look?

Hahaha.

"Don't worry about the father, and then the sons and daughters will ask Chu Ze for one."

"Hahaha, then we might as well be respectful!"

Hearing Zhu Biao say this, Zhu Yuanzhang suddenly laughed, and couldn't wait to take over the telescope from Zhu Biao's hand.

Then Mei Zizi returned to his position, followed the example of Zhu Biao just now, squinted his eyes and took the telescope to look east and west.

From time to time, a look of surprise flashed across his face.

"Good fellow, you're generous. I polished the lenses for hours just by polishing them, and you just gave them away? ”

Chu Ze, who witnessed the whole process on the side, complained while handing him the telescope in his hand after Zhu Biao sat down.

And Zhu Biao didn't mean to shirk, so he directly reached out and took it.

And he didn't forget to ridicule Chu Ze.

"How many hours have you been polishing your lenses? Are you sure you didn't let the guards or maids in the house polish it for you? ”

"Ahem.. I'm not mentally engaged! ”

Chu Ze said, and took out a smaller telescope from his sleeve again.

When he saw his move, Zhu Biao was suddenly a little speechless.

This guy is clearly on purpose

He prepared a lot in advance, but he didn't give it to his father, so that his father would find out and come to him to ask for it.

It is estimated that Chu Ze thought from the beginning that his father was absolutely embarrassed to ask Chu Ze directly, so he could only go to Zhu Biao.

"You guy, you're really careful."

After Zhu Biao smiled and made a joke with Chu Ze, he was about to raise the telescope again to check the situation at the test site.

Tilting his head, he happened to see Zhu Di sitting next to them looking at him with blank eyes.

"Big brother."

"Okay, okay, here you go.."

Facing his younger brother's pitiful eyes, the corners of Zhu Biao's mouth twitched, and finally sent the telescope he had just arrived out again.

And Chu Ze on the side, looking at Zhu Biao, who was empty-handed in the end, couldn't stop snickering at the corners of his mouth.

"Don't look at me! Just three, you sent it out yourself, don't say I didn't give it to you. ”

“.”

When he noticed that Zhu Biao was looking at the last telescope in his hand, Chu Ze directly put it away without a trace.

then directly and seriously rejected Zhu Biao's request that had not yet been made.

However, while they were talking, they found that Chu Ze's quasi-old father-in-law, Lan Yu, had already come to the side at this time.

"Virtuous nephew, that cylinder, borrow your father-in-law to take a look? Father-in-law definitely doesn't want you, just take a look."

When Lan Yu left satisfied.

Chu Ze, who also became empty-handed, faced with the gloating gaze cast by Zhu Biao, he could only spread his hands helplessly.

"It's all your fault, I'm idle and nothing to show off, now it's okay, we don't have anything to play."

"Hahaha"

Although the telescopes in their hands were taken away, in fact, for Zhu Biao and Chu Ze, these were only secondary.

Chu Ze can recreate it himself, so this thing is not unusual.

And Zhu Biao knew that Chu Ze could continue to get this thing.

So, sooner or later, he will have it.

Now...

Just let his father and younger brother play with it first, anyway, he had already experienced it just now.

After a period of frolic work, the guards who had gone to inspect the test site also moved all the targets that had been subjected to the bright lights.

At the same time, a third experiment is being prepared.

Looking at those scarred targets, Zhu Biao couldn't help but feel a little more confused at this time.

The reason why it is used is gunpowder brought out from the Shenji Battalion, and the shell of the grenade is also from the craftsmanship of the Shenji Battalion.

Why didn't the previous grenade explode?

Chu Ze just changed the shape of the gunpowder, and didn't add anything new.

Why is there such a big difference between the two experiments?

"How? Isn't it confusing now? Why do the same things have different results? ”

At this time, Chu Ze seemed to have a mind reading technique, looking at Zhu Biao's frowning brows, he directly expressed the confusion in the other party's heart.

"It's a bit of a thing, explain, explain? Of course, try to understand it in a way that I can understand. ”

After getting along with each other during this time, Zhu Biao also realized something.

Many words in later generations seem to be very specialized.

At the very least, it touches on the blind spots that they can understand.

"The general principle is that in fact, the combustion of gunpowder is mainly dependent on air. That is, when we breathe, we breathe into our stomachs. Invisible, but real. ”

"The main reason why the powdered gunpowder-filled grenade did not explode is that the powdered gunpowder particles are too small, leaving insufficient gaps between each other, and after filling the inside of the grenade, the air is insufficient, which affects the speed of gunpowder burning."

"And the reason why the grenade explodes is also because the moment the gunpowder burns, a large amount of energy and gas is released, which is equivalent to directly bursting the shell."

"When the granular gunpowder is filled, the air inside the grenade is more, so it burns faster and is more powerful."

As soon as Chu Ze's words fell, another roar spread out on the test site in the distance.

However, this time, both the sound and the tremor on the ground were almost twice as large as the previous one.

The sudden roar made Chu Ze and the others feel their ears ring.

"As for this time, the same material, the same amount of gunpowder, why is it so amazing, mainly because of the added sugar."

"When sugar and nitrate in gunpowder meet, a large amount of gas is released, which further accelerates the burning speed of gunpowder and the power of its explosion."

"This is one of the things that we learn in the afterlife."

"We call him chemistry!"

When the roar passed, looking at Zhu Biao, who was already a little stunned, before he could ask, Chu Ze took the first step to give an explanation.

A chapter in the late night file is in place, and the author is not too much to ask for a monthly pass, right?
