When the emperor starts to be unserious, things suddenly don't look good.

Changing those gorgeous clothes that make people want to stop is just the beginning.

And then he set his sights on carpenter's work, clanging all day long.

The furniture of tables, chairs and benches had been made out by Liu Wei a long time ago, and he didn't bother to do those gadgets himself. This time, Liu Wei is eyeing the real guys, catapults and movable siege crossbows.

For these two big things, Liu Wei used almost all the physics knowledge he had learned.

When he devoted himself to the study of large-scale siege weapons, people were not bored.

Even women are not interested anymore, and the compulsion rises instantly.

But Liu Wei is very serious in his eyes, but the ministers don't see it that way.

Because of the clothes given by Liu Wei, Cao Cao and Zhu Jun supported their waists for more than ten days.

Knowing that the emperor was making a big move again, the two hurriedly got together.

"Zhu Situ, it's time to persuade Your Majesty, it's not a matter to go on like this." Cao Cao said as he held his waist.

His recent days have been very good, but in addition to the good, it also makes him a little uncomfortable.

That kind of thing has been tossed for a long time, and it is really expensive.

But the clothes that the emperor improved with his own hands made him a little.

Zhu Jun can be said to have a deep sympathy for this, and he sighed and said, "I don't know what Your Majesty is transforming this time."

"Does Situ still want His Majesty to reward him with a few more sharp weapons?" Cao Cao teased and chuckled, "I'm young and young, but I can still withstand it, but Situ is ...... age It's not that small anymore."

Zhu Jun smiled and said, "The old man's sword is not old. No matter how much Your Majesty improves, that little thing will be like that, and there can't be too many tricks, so General Cao doesn't need to worry so much."

Cao Cao smiled mysteriously and said, "Situ, what you said is too full, there is no absolute in this matter. When His Majesty came down at leisure, I found that it was really a spring of ideas, and all kinds of strange things could come out."

"In case, Your Majesty will get some magic medicine, or improve those clothes and make up some dazzling music and dance. Moreover, Situ does not have to doubt that after His Majesty has done it, he will definitely reward it and rejoice with his ministers."

Zhu Jun's face changed suddenly, and he immediately said very seriously: "You should indeed advise Your Majesty, don't indulge in and enjoy!"

"Actually, if Your Majesty rewards some such magical things every once in a while, I actually like it very much, but so often, it's really ......" Cao Cao said with a sigh, "It's hard to resist."

He really liked it, but the body was a little resistant.

Zhu Jun smiled, "You dare to tell the truth. Let this matter be admonished, and you and I will go together to meet you."

"Zhu Situ, please!" Cao Cao raised his hand, "Xiaguan has always liked to tell the truth and do practical things."

Zhu Jun was noncommittal, Cao Cao's words, he didn't even believe his tone.

The two of them met together, and in the spacious backyard where the emperor was walking, they did not see the artifact they thought they would have.

Instead, I saw two behemoths.

"Your Majesty, Your Majesty!"

Zhu Jun and Cao Cao saluted, but their eyes almost couldn't be pulled out of the two behemoths.

Both of them are battlefield veterans, and at a glance, they can guess the identities of these two big guys - siege equipment.

"You're here just in time, are you serious? If it's okay, I'm talking about it in advance, and if it's okay, I'll think about it together!" Liu Wei was covered in sawdust and walked out of a pile of wood.

Zhu Jun said, "The ministers heard that His Majesty has not been out for several days, so they came to take a look, and there is nothing serious!"

"It's not serious, that's good." Liu Wei climbed onto the catapult, "You're not unfamiliar with this thing at all, right?"

Catapults were born during the Warring States period.

But hesitation is too large and inconvenient to transport, and it is rarely used in ordinary warfare.

Liu Wei made this thing fierce

It was changed, covered with iron sheets, supported by iron rods, and made detachable.

The distance of the stone throwing has also been improved from the original 60 steps to 100 steps.

But Liu Wei wanted to make a big one this time and be the ancestor of gunpowder.

But after repeated attempts, he, a person who was born in a professional class to play this thing, never got it right.

I tried it a few times, watched the fireworks a few times, and almost broke his hand.

"Your Majesty, if the minister is not mistaken, this should be a stone thrower. It's just that this thing is very different from the stone thrower that the minister has seen, and at first glance I really don't recognize it." Cao Cao stepped forward and looked at the catapult carefully.

"You didn't recognize it, because it's not done yet." Liu Wei patted the stout wooden pillar on the catapult and said, "Now there is a small problem, this nitrate two sulfur three charcoal I know very well, but after making it, it has never been powerful, you ponder for me."

Zhu Jun and Cao Cao were confused, what is this?

None of them had heard of it.

"Nitrate is fire, that's what it is." Liu Wei took out a piece of saltpeter from the wooden box on one side, "One catty of this thing, plus two taels of sulfur and three taels of charcoal, can make a very sharp weapon that can be beaten. So you understand?"

"Your Majesty, why don't you give it a try?" Cao Cao said.

Liu Wei was waiting for this sentence, "Okay, you can try it, but be careful, once this thing explodes, although it will not kill you on the spot, it can easily break your arms and legs."

Cao Cao's neck shrank suddenly, how could he feel that the emperor seemed to have bad intentions?

Since this thing is so dangerous, it is necessary for the dead to try it.

Oh, he volunteered to do so.

The matter has come to this point, and Cao Cao can only bite the bullet.

"Your Majesty, this thing is dangerous, why don't you choose the dead?" Zhu Jun also said.

Liu Wei waved his hand and said casually, "Don't be so nervous, be careful, it's okay, I tried it myself."

Hearing this, Cao Cao suddenly relieved himself, what the emperor dared to try in person, what else did he not dare!

Under Zhao Ye's service, Cao Cao very carefully packed these things into the clay pot, and then put the lead.

"Your Majesty, should this mouth be sealed?" Although Cao Cao didn't understand the principle of this thing, he played with a lot of urine bubbles when he was a child, and that thing was a good thing for disgusting people.

Liu Wei suddenly realized that he had just listened to the fireworks before, and what was the problem.

The seal is not good enough!

These clay pots, because of the firing problem, must have left a lot of small pores on them, which are not enough to seal.

而且，老式的喷子里面装的都是碎石、铁粒，所以才具备了杀伤力，而他也没有放。

"Wait!" Liu Wei stepped forward with some excitement, opened the crockpot that Cao Cao had already packed, stuffed two handfuls of gravel into it, and wrapped it with another layer of wax.

After doing all this, he said to Cao Cao very solemnly: "Success or failure is here, everyone else, hide!"

Cao Cao looked at the courtyard that was empty in an instant, and his wrist couldn't help but tremble.

This thing is definitely dangerous.

He carefully lit the fuse, and then ran away.

Kankan hid in the house, and suddenly there was a loud muffled sound behind him.

Rumble!

With this loud sound, the rubble splashed, and the window lattices and door panels clicked.

A new era was born in such a hurry.

Cao Cao looked at the dust and smoke all over the ground, and his face turned green all of a sudden.

This thing...... Is it so fierce?

If he had just stayed in the courtyard, or had run a little slower, he would have been as virtuous as the door panel by now.

The door panel can still resist a resistance, if he is punched out of such a deep hole, he should ...... It's dead, right?

"Mengde, you deserve to be my blessed general!" Liu Wei looked delighted

He praised, "I've been thinking about it for so many days, and I can't get out of it, and I didn't think about the problem of sealing at all, and your words woke me up in an instant!"

"You have created an era that has changed the shape of warfare in the future."

Cao Cao's eyes were straight, and he was a little unconscious, and his back was completely soaked.

"Your Majesty, this ...... You've tried it yourself before?" Cao Cao stammered.

He was shocked, but also a little worried about the emperor's guts.

It's really easy to get dead playing this kind of thing.

"I don't try it myself, and neither will anyone else." Liu Wei said casually, "Zhao Ye, get another one, let Situ let it go!"

Zhu Jun: ???

He wants to refuse!
