Li Yanran said to Li Feng as she walked.

That's right, you're not mistaken, Li Yanran is going to be the gunpowder of China's four great inventions.

It's just that it is not certain whether there is black powder now, and even if there is, it is the most primitive, and the explosion power is too small, and it is not taken seriously.

All she had to do was to put the gunpowder in front of everyone in advance and give those Tibetans a long insight.

"Whoa."

Li Feng nodded, and immediately went to find what Li Yanran wanted.

"Sister, what are you going to do?"

Li Hong looked at Li Yanran, and he didn't know what his sister wanted to do?

Why do you suddenly want these things like a convulsion?

"You'll find out later!"

Li Yanran showed a trace of coldness on her face, the easiest two steps for black powder to increase its power.

One is purification, and the other is the ratio of three materials.

She can't do it for the time being, but it's okay to change the ratio.

The folk mantra is one nitrate, two sulfur and three charcoal, and add some sugar to Big Ivan, which she still knows.

But this was not the optimal ratio, and it was accepted that it was fifteen parts saltpeter, three parts charcoal, and two parts sulfur.

As long as you make a little adjustment, it depends on how you Tubo people die.

“？？？”

Li Hong's face was full of question marks, and he didn't know what kind of medicine his sister's gourd was selling.

It didn't take long for Li Feng to turn back with what Li Yanran needed.

Looking at the objects wrapped in paper, Li Yanran was also excited.

I watched a lot of this gunpowder on TV, and I did it myself, and it was really the first time that a big girl got on a sedan chair.

Command Li Feng to divide these things and put them in front of him one by one.

"Put it in a mortar in the ratio of fifteen parts saltpeter, three parts charcoal and two parts sulfur."

"Whoa."

Li Feng acted quickly, and soon put saltpeter, charcoal and sulfur into the stone mortar according to Li Yanran's ratio.

Then he picked up a stone pestle and began to pound it vigorously.

After a while, all the contents of the stone mortar turned into powder.

"Sister, what the hell is this?"

Looking at Li Feng's movements, Li Hong's curiosity was already uncontrollable, and he tilted his head and asked Sister A.

"It's called black powder, and it's delicious."

Li Yanran glanced at Li Hong, and said that you will know later, why do you keep asking?

Are you a hundred thousand why?

Don't you know that curiosity can kill a cat?

"Delicious? I don't believe it! ”

Li Hong's eyes were full of suspicion, and he took a little gunpowder with his hand and put it in his mouth.

"Phew, bah, bah."

With the entrance of gunpowder, Li Hong's whole person was not good.

There was a bitter and strange taste in the mouth, and there was a burning sensation on his tongue that almost made him vomit.

“？？？”

Seeing Li Hong's movements, Li Yanran was stunned.

What kind of ghost animal action are you, that's gunpowder, not powdered sugar, are you crazy?

"Li Feng, get the water!"

Li Yanran grabbed Li Hong over, and while clasping his throat with her fingers, she asked Li Feng to fetch water.

"Gross!"

was clasped by Li Yanran's fingers, and Li Hong instantly couldn't hold back, and spit out in a big gulp.

After Li Feng brought water and rinsed Li Hong's mouth, Li Yanran was relieved.

"Sister, you liar, this is unpalatable!"

Li Hong looked at Li Yanran in front of him aggrievedly, and his little eyes were already overflowing with tears.

Sister is really bad, such an unpalatable thing, she actually deceived me into being delicious.

Doesn't your conscience hurt?

Li Yanran raised her hand and slapped Li Hong's head, looking at her little brother with a dark face, her eyes full of anger.

"You don't want to die? What about the brain? Thrown into a fiefdom? Is this something that can be eaten? ”

still dares to sue me, Li Yanran really wants to kill him now.

Do you dare to taste gunpowder? Do you really think you are Shennong?

Even if it is Shennong, if you eat too much of this thing, you will die and have no place to be buried.

"Sister, you said it was delicious, and now you blame me?"

After receiving this slap, Li Hong also stared at Li Yanran angrily with his neck.

It's not that I want to taste it, it's that I trust you too much.

Sister, you have thrown my trust out of the clouds.

"I said delicious? Didn't you judge it yourself? ”

"I also said cow dung is delicious, will you eat it?"

"When will you grow up? Let me worry less about snacks? ”

Seeing that Li Hong dared to talk back, Li Yanran also turned on the combo mode and bombarded his little brother.

"Don't scold, don't scold, little brother, I know it's wrong!"

Facing Li Yanran, who was full of firepower, Li Hong had no power to resist at all, so he could only cover his ears and beg for mercy in vain.

"I'm really pissed off, next time I'm so stupid, don't say you're my brother."

Li Yanran turned her head in anger, not wanting to look at her stupid brother.

"Miss, what should I do after that?"

Li Feng shook his head, His Royal Highness the Prince's brain was really a little insufficient.

"After."

To be honest, Li Yanran doesn't know what to do next.

The ratio of gunpowder is simple, but how to apply it?

You can't be a bomb!

In this way, not only will the Tibetan envoys die, but I am afraid that the ministers in the banquet hall will not be spared.

If you blow up your dad at once, this joke will be too big.

But what about the assault rifle?

She only knew that it was made of bamboo, but she really didn't know how to do it.

"Let's try the power of this black powder first."

After thinking about it for a while, Li Yanran directly asked Li Feng to split a bamboo, filled it with black powder, and twisted a fuse with paper and inserted it into the master's opening.

"Run."

Everything was ready, Li Yanran also lit the long fuse, and then ran away.

When the two saw Li Yanran running wildly, they also followed her and ran into the distance.

The three of them hid behind a big tree and watched the lead burn slowly.

"Sister, what's the situation?"

Li Hong looked at his sister with a depressed face, not knowing what she meant?

"Don't worry, let the lead fly for a while!"

Li Yanran said that it was fake if she didn't panic, after all, this was the first time she had done this thing, and she didn't know the specific effect.

"Let the lead fly for a while?"

Li Hong is even more puzzled now, Sister, don't you play dumb riddles, okay?

If this continues, I'll die!

"Peng!"

A puff of white smoke was accompanied by a thunderous bang, and the bamboo tube was directly blown apart.

"Poof."

The sudden explosion directly scared Li Hong into a butt squat.

His eyes were full of horror as he stared at the bombed land.

"What sound?"

"It's like a place in the Imperial Garden."

"Come and see!"

The nearby chamberlains all heard the explosion, and they all ran over without daring to stay.

“？？？”

Looking at the things in front of them, everyone was stunned.

What just happened here? Why are the two Highnesses here?

"Your Highness, are you all right?"

An attendant hurriedly saluted Li Yanran and Li Hong and asked them if they had anything to do.

"Whatever can happen in this palace, get out of here, no one can get close to here!"

Looking at the person who suddenly rushed out, Li Yanran's brows were directly twisted together.

This is his secret weapon, if someone leaks the news, it may be a disaster for Datang.

“？？？”

Waiters, you look at me, I look at you, and I don't know what to do for a while.

"Didn't you hear my sister's words? Hurry up and get out, stay here again, this palace gouged out your eyes. ”

Seeing that they didn't listen to their sister's words, Li Hong's face was also cold, and he shouted angrily.

"Whoa."

"Whoa."

"Whoa."

glanced at the angry Li Hong, and the attendants were also shocked, so they ran away.

The shadow of the tree of human life, Li Hong's prestige is well known in the palace.

If you really think about the other party, you don't know what will happen.

Looking at the attendants who disappeared in an instant, Li Yanran also gave her younger brother an approving look.

In the end, it is the palace overlord, and it is really powerful.

"Sister, this. This thing is terrifying! ”

When Li Hong came to the place of the explosion, his heart was already like turning over a river and a sea, and it was difficult to calm down for a long time.

If it weren't for Sister Ah running away with her in advance, he wouldn't know what he would be like now.

"So now you know how dangerous you are!"

Li Yanran glanced at Li Hong, now you know how powerful!

This gunpowder can not only explode, but if you really eat too much, it is a poison that pierces the intestines, and the gods are difficult to save.

"Uh-huh!"

Li Hong nodded with palpitations, if these things really entered his stomach, they would be banging.

I'm not going to be blown up.

Feeling the power of gunpowder, Li Yanran also began to think about how to get the assault rifle that was only available in the Song Dynasty.

Let Li Feng open up the inside of the bamboo, and then carefully fill the gunpowder into the bamboo tube and compact it.

Then he found a wooden stick and put it against the back of the bamboo tube.

Finally, the iron ball was pressed into the main pipe, and a small hole was drilled at the bottom of the bamboo tube to be used as a filling lead.

After everything was done, Li Yanran found a big problem again.

How do you experiment with this thing?

If you hold it, will it explode?

If this thing blows up, it's gone.

"Miss, let me try!"

Li Feng saw Li Yanran's hesitation, and directly took the bamboo in his hand, his eyes full of perseverance.

"No, go get a bench."

Li Yanran shook her head, she naturally wouldn't let Li Feng take the risk.

This is his absolute cronies, and he can't be defeated in terms of seniority.

"Whoa."

Li Feng put down the bamboo and immediately went to move a bench out.

Seeing the bench, Li Yanran directly ordered Li Feng to tie the freshly made assault rifle to the bench, and then pointed the muzzle of the gun at a big tree.

Li Yanran lit the fuse with a fire fold, and then ran away.

Li Hong and Li Feng knew that they were powerful, and they also followed Li Yanran for the first time.

"Fool, run in the opposite direction of the bamboo!"

Seeing Li Hong running towards the front of the assault rifle, Li Yanran was also taken aback and hurriedly shouted at him.

Hearing this, Li Hong also shuddered, and hurriedly turned around and ran wildly.

"Peng."
