I am the cook, but I am Li Er's son-in-law

Li Shimin went to Tongfu Restaurant in disgrace the next day.

He couldn't figure it out. He clearly imagined it so well, but when he actually put it into practice, he could make such a big commotion. If it wasn't for the young imperial doctor, who was only in his 50s, and could still run, he would have been scared. It's about killing people.

Arrived at Tongfu Restaurant.

Li Shimin didn't open his mouth to mention what happened yesterday.

He first ordered a few new dishes, such as braised pork ribs and winter melon pork rib soup, and then asked if the new wine was still brewed.

After Yin Xuan came out with the dishes and took a few mouthfuls, Li Shimin raised his hand, bowed to Yin Xuan, and said softly: "Shopkeeper, I have something to ask you."

Yin Xuan nodded, got up from his seat, and sat opposite Li Shimin: "Say it."

Li Shimin paused, pondered for a while, spat out the bone in his mouth, and said, "Shopkeeper, aren't you teaching my two daughters about gunpowder recently?"

Yin Xuan nodded.

Li Shimin continued: "I thought about it, and I think this thing may be of great use in war."

"But it's just that the gunpowder you taught me to my two daughters is mediocre, so I thought about it and wondered if I could improve the formula of the gunpowder."

"But last night, I sent someone to test it, and there were some small problems."

Seeing Li Shimin's wrinkled face, Yin Xuan couldn't help but feel a little bit in his heart.

"You didn't add phosphorus, did you?" Yin Xuan's voice trembled.

Li Shimin nodded, and replied: "En."

Yin Xuan couldn't help taking a breath.

The reason why he immediately thought of "phosphorus" has nothing to do with the case of the temptress Yuan that he helped Zhou Xiaosan solve.

But he had such an experience in his previous life, of course, not himself.

It's a little friend in the compound, not satisfied with the black powder he made, only so powerful.He is as clever as Li Shimin, adding some "phosphorus" to the material.

Of course, he was well aware of the flammable properties of phosphorus, so instead of getting white phosphorus, he got some red phosphorus.

The clever little brain allowed him to get the reward he deserved - he didn't go to class for two months, he lay in bed every day without getting out of bed, and even had someone to feed him.

Most of his body was covered with blisters.

Compared with white phosphorus, red phosphorus has a higher ignition point, but it is still phosphorus after all. After being crushed for a while, it burst into flames.

He was also rejoicing, fortunately, the red phosphorus burned early. If the black powder exploded later, it would not be as simple as burning the skin.

"How did you come up with that?" Yin Xuan was a little speechless, "Phosphorus has such a low ignition point, and you are still rubbing against it to generate heat. This is not courting death. Is that person still safe?"

Li Shimin exhaled: "People are quite safe, but they just burnt their robes."

"So it's wrong to add phosphorus to gunpowder?"

Hearing that the person was fine, Yin Xuan heaved a sigh of relief, shook his head, and smiled slightly: "Who said it was wrong?"

Li Shimin's eyes lit up.

But what Yin Xuan said next made him feel blocked.

"But it is very difficult to achieve this step. You should not toss about it. If you lose your life, you still can't get it out."

Li Shimin pursed his lips, gnawed another rib, and knocked on the table: "The shopkeeper, I wonder if your gunpowder formula is for sale?"

Yin Xuan glanced at Li Shimin strangely: "Didn't I teach your daughter the formula of gunpowder?"

Li Shimin shook his head: "I'm not talking about the things you used to make them happy, but the more powerful gunpowder you said."

Gunpowder that is several times more powerful than black powder.

During this period of time, Li Shimin was haunted by this thing, and Empress Changsun said more than once that when she was sleeping, she would always say the word "gunpowder" in her mouth.

Yin Xuan shook his head decisively: "Not for sale."

Li Shimin spread out his hands, and said heavily: "Shop, you can set a price as you like, no matter how much it is!"

Yin Xuan still shook his head: "Not for sale!"

His attitude was very firm, no matter how much Li Shimin offered, he would never be able to sell a better explosive formula.Not to mention the limitations of materials and equipment.

After these things have a direction, they can be ground out slowly.

Have you ever seen someone who fished and threw the bait directly to the fish?
How to fish when the bait is gone?

And Yin Xuan is very clear that it is best for him to maintain a clean money transaction with Li Shimin and the entire court of the Tang Dynasty, and the relationship between restaurants and customers is the best.

There is no need for me to get involved in the court.

Black gunpowder is not powerful enough. Yin Xuan took it out just to make firecrackers and fireworks, even though Yin Xuan said that he had more powerful gunpowder in his hand.

But after all, Yin Xuan didn't take it out, so this thing is in a "Schrödinger" state.

Li Shimin couldn't be sure whether Yin Xuan really had this thing, or whether he just had a mouthful, and said it casually - even if Yin Xuan's previous performance was enough to prove that he would not tell lies.

Before Li Shimin was sure, he could only be like a donkey attracted by carrots, circling around the millstone of Yin Xuan.

Even if Li Shimin is a dragon in donkey skin.

As long as Yin Xuan is not going to use Li Shimin's identity to pretend to be a tiger, and just tease the donkey with carrots, then Li Shimin will have to keep the donkey in.

The longer he pretended, the less Li Shimin dared to tear off the donkey's skin.

This is the purpose of Yin Xuan's words.

Li Shimin rubbed his hands, and quoted several prices, such as ten thousand guan copper coins, gold, silver and precious stones, but none of these moved Yin Xuan.

Li Shimin didn't force it.

Compared with gunpowder technology, Li Shimin wanted Yin Xuan more - after all, besides gunpowder, Yin Xuan had many other outstanding features.

He sighed softly and looked at his two daughters.

If I can't do it, then it depends on my daughter's ability!
Li Shimin raised his head and gently stroked his chin.

My two daughters are just too naive. They only know how to study all day long and don't know how to do other things.

Do you want Concubine Wei to teach them some skills to capture men's hearts?

If this goes on like this, I hope that my two daughters will get Yin Xuan out, what's more, what's more, Li Shimin has heard that Li Jing, the little old man, seems to be encouraging his daughter
If the little old man Li Jing snatched Yin Xuan away in the end, where would he put his face as an emperor?

Li Shimin stopped talking and concentrated on eating the ribs.

Yin Xuan turned around and continued to look at the test paper Li Lizhi and the others were working on.

In front of Mingyue Tower.

Yi Xin took a deep breath, raised his foot and walked in slowly.
