Zhu Di rode directly on a fast horse and rushed towards the place of the incident.

The guards and eunuchs in the back were frightened crazy, and Mu En fought hard, urging the horses to chase after him. Is this a joke? There are rules for the Son of Heaven to go in and out, how can anyone run out casually. And there was just a bang outside, the ghost knows what happened, how can he let the Son of Heaven put himself in danger!

"Your Majesty, the minister has closed the city gate, please return to Your Majesty!"

The city gate official relied on his courage to stop him, but Zhu Di didn't speak, he directly drew out his sword and pressed it on his neck!

"Open the door! Don't let me spit at the foam! ”

The city gate officials were all paralyzed with fright, the sword had already cut the flesh, and there was no need to doubt that if they said a word, they would immediately turn into corpses.

"Open, open!"

Zhu Di didn't wait for the city gate to be completely open, so he rushed out first.

The city gate officials were stupid, and they didn't know whether to close it or open it.

"Get out of the way!"

While he was stunned, a horse flew over his head and rushed straight out.

The city gate official was stunned for a while before realizing that it was Lord Liu!

Lord Liu chased him out, what's wrong with it today, why are you crazy?

His emotion was not over, and in the back, the crown prince Zhu Gaochi, and the king of Zhao, Zhu Gaosui, rushed over one after another. What else is this gate closed, I just don't know if there will be more scary ...... While he was pondering, a horse galloped up.

"Get out of here!"

It turned out to be a woman's voice!

The city gate official said that I was too unlucky, why did the girls dare to scold me?

He was just about to reply, when he suddenly realized something, quickly shut up, and really rolled to the side, seeing a team of female soldiers rushing out, the city gate official closed his mouth tightly, for fear that his heart would jump out!

Damn!

Hell yes!

Why is the queen crazy too?

Where can I make sense?

The city gate official complained frantically, Xu Miaoyun didn't care about anything, she quickly urged the war horse, and came to the outside of the school hall as fast as possible, at this moment, in the sky, there was a cloud of yellow smoke, in front of her, there was a charred ruin, smoking curling smoke.

Xu was stunned and almost fell off the horse.

Finished!

What about the son?

She pounced as if she was crazy and rushed directly towards Zhu Di.

"What about my son? How is he? ”

Zhu Di didn't come much earlier, and all he saw was a piece of scorched earth. Zhu Gaoxu is gone, is he really dead? My good son, just gone?

Zhu Di was furious, and roared left and right, "What are you doing in a daze, go find someone!" Before he could finish speaking, Xu rushed over, she had long forgotten her identity and only wanted to find her son.

"Xu'er, Xu'er! Don't scare the queen mother! I told you a long time ago, don't do such a dangerous thing, you just don't listen, if you have three long and two short, what should my mother do? ”

Xu was crying profusely, and at this time, someone suddenly coughed in a low voice, "Mother, the child is fine!" ”

"Pretty good? Fart! Xu scolded, "It's blown up, can it be good?" Son, aren't you a ghost? ”

Zhu Gaoxu could only turn to his mother and said in a low voice: "Do you want to ask the queen mother to see it for herself?" ”

Xu Shi was stunned for a moment, jumped up, hugged Zhu Gaoxu, checked from head to foot, and smelled it, there was no burnt smell.

"Xu'er, you're really okay! How did you get out? ”

Zhu Gaoxu grinned, "Queen Mother, the child has long been out of it, not only the child, but also my helper." ”

At this time, Zhu Di, Liu Chun, Zhu Gaochi, and Zhu Gaosui all gathered over, and Zhu Di said with a black mouth: "What's the matter?" You make it clear to me! ”

Zhu Gaoxu spread his hands, "Father, the son has just come back, I was originally going to verify the gunpowder, but when I heard an explosion here, I rushed back." ”

Zhu Di was stunned, "So, someone detonated the gunpowder?" ”

Zhu Gaoxu shook his head, "No, my gunpowder here is stored separately, and the management is very strict, how can it explode easily?" Zhu Gaoxu also has a headache, he has always wanted to surprise the world, and he has been busy all night during this time, rarely resting. But that's just the point.

The explosion just now did what he wanted, but the problem was that he didn't know what was going on.

At this time, Liu Chun came over, "Follow me to see what the hell is going on." ”

Liu Chun stepped into the middle of the ruins, looked carefully, and gradually, Liu Chun found a place where the explosion was the most violent and the most damaged, the walls were completely blown up, and a crater appeared on the ground.

"What is this place?"

Zhu Gaoxu looked left and right, "Master, it should be the storeroom." ”

"What to store? Is it something that can explode? ”

"It's not!" Zhu Gaoxu hurriedly shook his head, "There's a dye I made some time ago here." ”

"Dyes? Dye or something? ”

"It's the one that dyes silk, and the dyeing workshop doesn't like it well, so I throw it here."

Liu Chun frowned and muttered for a long time, "Are you talking about a yellow one that can be dissolved in water?" ”

Zhu Gaoxu nodded, "That's right, Master, how do you know?" ”

What else could Liu Chun say, all he left was to look up to the sky and laugh.

"Master, don't laugh, the disciples are stunned!" Zhu Gaoxu's eyes were red.

Liu Chun nodded and said, "You are really stupid, this thing is wasted as dye, and the real use is explosives!" ”

Liu Chun woke up the dreamer with a word!

Zhu Gaoxu couldn't believe it, could it be that what he had been pursuing had already been researched? The three brothers of the Zhu family each have an inheritance here in Liu Chun.

Zhu Gaoxu originally did the best in mathematics, physics and chemistry, but after the Jingjing tribulation was over, he put aside military affairs and devoted himself to studying these things.

Although Liu Chun's level is not high, he at least knows some development paths, and he doesn't need to rely on luck like buying a lottery ticket.

Therefore, Zhu Gaoxu quickly figured out the basic acid and alkali, and then began all kinds of tossing. Of course, Tao Chengdao also made a lot of effort in this field, he was not satisfied with the hot air balloon for a long time, and wanted to find a better way to go to heaven.

They kept tossing and turning, and they really came up with a lot of things, including the main ingredient that exploded today: picric acid!

Zhu Gaoxu swore that he really didn't expect this thing to explode.

Today he was experimenting with firearms at the shooting range, and someone from the dyeing shop came to pick up picric. It happened to be a newcomer, and he was in charge of looking at the warehouse, and found that the barrel containing the bitter acid could not be opened.

This kid is also reckless enough, he even knocked it with a hammer!

He didn't stop with a hammer, and the bitter acid made by Zhu Gaoxu, along with other things, all exploded.

After figuring out the truth, Zhu Gaoxu's head hurt a little, "Master, is this my invention or that kid's invention?" ”

Liu Chun almost wanted to give him two feet, "Count it as your invention, but he lit the fire!" ”

Zhu Gaoxu finally grinned and said happily: "It's still the master who can tell the difference!" He's also a hero, I'm going to reward him heavily! ”

Liu Chun snorted, "It's not okay to reward him, let's leave it to his family!" ”

Only then did Zhu Gaoxu realize that the unlucky guy had been blown to pieces.

If Zhu Gaoxu was also there at that time, it is estimated that he would be injured if he did not die.

It's scary to think about.

However, after a short period of fear, Zhu Gaoxu fell into ecstasy!

He's just a few kegs here, and he's so powerful! And after the explosion, very little scum remains...... High power and less residue...... Isn't this the perfect powder he is after?

It's done!

It really happened!

Zhu Gaoxu seemed to be crazy, running everywhere and yelling wildly!

Really made him do it!

After all these years of painstaking experiments, it has finally come to fruition!

And he did!

Xu Shi was frightened when he saw his son running wildly, "What's the matter?" Was Xu'er scared out of her mind? ”

At this time, Zhu Gaosui said quietly: "He is not scared, but happy!" ”

Zhu Gaochi also followed: "Congratulations to the second brother, he has made a fortune!" ”

Xu's brains are not enough, "What makes a fortune?" Did you get it clear? ”

Zhu Gaosui said: "Queen Mother, how clear this is, the second brother has discovered a more powerful gunpowder, and the value of this thing is immeasurable!" Put it on the firecracker and artillery, it can also be used to open mountains and build roads, blow up ore veins, and sweep away overseas ......" Zhu Gaosui suddenly remembered something and jumped three feet high.

"Big brother, you explain to our mother, I still have something!" Zhu Gaosui ran away after speaking, he was even crazier than Zhu Gaoxu! In a hurry, this kid went crazy and snatched away his father's royal horses.

For him, time is money, start early, get rich early!

New gunpowder came out, and then there were factories, minerals, and related to weapons, overseas development, and ...... There are many places where gunpowder is needed, how much is that?

Zhu Gaosui seems to have seen a mountain of gold, uh no, it's a large mountain of gold!

Really made a fortune!

The second brother experimented, he picked up the benefits, this division of labor is very good, Zhu Gaosui said that the more in the future, the better!

"Father, mother, the child has succeeded!"

Zhu Gaoxu dusted off his body, he tried to stay calm, but his trembling hands betrayed his surging heart! New gunpowder, new power, Master is right, science is indeed a power to change the world, as long as you master science, you can do whatever you want!

Zhu Di breathed a sigh of relief, "It's okay if you're fine, don't do these dangerous things in the future, and see what it scares your queen mother into!" ”

Zhu Gaoxu hurriedly bowed to the queen mother, "The child is not filial, which makes the queen mother worried." ”

Xu felt that the second child was more sensible today than ever before.

"Don't say anything, go back to the palace for a feast."

Zhu Gaoxu shook his head slightly, and then said with a straight face: "Father, mother, or master, I have an idea, I plan to publish the formula of gunpowder!" ”

"What?"

This time it was Liu Chun's turn to be surprised, "You have to think clearly, this new type of gunpowder is amazingly powerful and incomparably valuable." If you hold it in your hands, you will make at least tens of millions of taels of profit every year! ”

Zhu Gaoxu shook his head vigorously and said with a smile: "The disciple is also a coincidence, and the disciple announces the gunpowder formula, which can also let the world better understand the means of our scientific lineage, and can make a name for science, not the price is very measured." ”
