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

After eating the potato cakes, Li Lizhi and Li Shu silently wrote down Yin Xuan's humble room inscription, asking for details so as not to make mistakes.

Li Shimin walked in holding a sign.

"Shopkeeper, come and take a look, this is a gift from me!" Li Shimin yelled loudly before entering the door. The guards behind him wanted to help, but Li Shimin refused.

Just a plaque.

Yin Xuan was taken aback, for no reason, why did Li Shimin give him a gift?
He stepped forward to give his hand, and put the plaque on the table. It was a vertical plaque with five large characters on it, "The First Building in the World".

The pen is crisp, strong and strong.

Li Shimin was very proud: "How about it, shopkeeper, how do I write this word?"

Yin Xuan pretended to understand and nodded: "It's pretty good."

"Yesterday, I heard from my little girl that someone held a literary meeting at your restaurant in Xuanduguan. It's a pity that yesterday was busy and I didn't have time to come out."

"Today I will send a congratulatory gift to the store."

Of course, he wrote down these five characters as an ordinary Li Shimin, but the shadow of a person and the name of a tree.

Yin Xuan can save this.

He yelled into the kitchen and asked Gao Tie to hang the plaque outside the door.He doesn't know calligraphy, but he heard from an ex-girlfriend from the Chinese department in his previous life that Li Shimin's calligraphy is actually not bad.

Although he can't reach the level of Song Huizong, he is still a master of calligraphy.

Of course, there are many people who think that Li Shimin's technique is actually "I don't know why the distribution is white, and there is no loss of strength."

It sounds like a compliment, but in fact it is like someone praising others for their good looks, but in the end they only say "looks happy".

But if you don't have the ex-girlfriend when you broke up, you should be able to believe it.

There's no shame in hanging out.

Anyway, if it's not good, it will be Li Shimin who will be scolded at that time, not him.

Li Shimin ordered two dishes and ordered half a catty of wine. After a few mouthfuls, seeing that it was not time for lunch, he invited Yin Xuan to sit down opposite him: "Shopkeeper, that gunpowder is really shocking."

After getting the idea of ​​gunpowder as a driving force from Li Lizhi, Li Shimin sent his general to be the supervisor, made a large "firework" and polished some stone balls.

The material of fireworks tubes was first made of wood.

However, if you put too much gunpowder, before the gunpowder can push the stone ball out, the wooden pipe will explode by itself. The person who will be the prisoner for the first time has no experience, and he didn't follow Li Shimin from Li Lizhi. The safety regulations of the country were regarded as one thing, and many people were injured.

Later they became honest.

An An complied with the operation rules, returned the armor all over his body, and covered his face with a layer of iron cloth, only two eyes were exposed, for fear of any problems.

If there is less gunpowder, the stone ball cannot fly out, otherwise it will not fly very far, and it will have no power at all.

Later the pipe was replaced.

Exploding the chamber, exploding the chamber, exploding the chamber. It became the daily life of the prisoner, but after all, he is a skilled craftsman who is one of the best in the world, and he quickly solved this problem.

Yesterday morning, a stone ball was successfully shot, and within a hundred steps, it pierced through the walls of the palace and caused a roar in a camp of the Jinwu Guard.

Qian Niuwei didn't know about it, and thought it was a rebellion, so he quickly reported to Li Shimin.

Li Shimin was also stunned, put on his armor and went into battle, only to realize that it was an oolong.

I heard people from the Jinwu Guard described that they were eating and singing when they were suddenly hit by something. The brilliance was like a meteor smashing the world, and a brother's leg was broken by flying bricks.

They thought someone had attacked the palace
Li Shimin didn't know whether to laugh or cry, but he had a deeper understanding of the power of artillery. Within a hundred steps, he could actually break down the walls of the palace?
On the spot, [-] pens were allocated to the supervisor, and they were asked to continue to vigorously study this thing. Well, [-] pens of them were used to repair the wall.

"Did you use it as a weapon?" Yin Xuan glanced at him and asked casually.

Li Shimin was choked up, and glanced at Li Lizhi and Li Shu: "Did they tell you?"

Yin Xuan shook his head: "Although you are not young, it can be seen that you are a restless person, similar to Yin Lulu, thinking about doing "earth-shattering" things all day long."

Li Shimin stared!

Can it be the same?

What did Yin Lulu do?Going to the house to expose tiles, frying fish and beating chicken, can you be the same as yourself who is thinking about blowing up the imperial city?

Dare to ask the world, except he has the guts to blow up the imperial city, others let them do it, do they have the guts?

"Tell me, how far have you researched?" Yin Xuan waved his hand, blocked Li Shimin's next words, and continued to ask.

Li Shimin was honest and told the progress of the general prison.

By the way, the general supervisor's current problems were mentioned.

Bomb, Bomb, Bomb.

Yin Xuan shook his head: "It's not easy. You ask your family to make the barrel thicker. If you want to save materials, then make it thicker where the gunpowder explodes."

Li Shimin nodded, this is really a simple and rude solution.

"By the way, there is one more question." Li Shimin took a sip of his drink and asked again, "It's not so easy to ignite gunpowder now."

"They still use cork. I don't know if the store has a better way."

Yin Xuan shook his head and waved his hands: "This is the homework of your two girls. I still have a bet with them. I can't tell you."

"Wait for your girl to research it by herself."

And a bet?

As a father, he didn't know about this. No wonder the two of them studied fireworks so hard every day recently, thinking that they wanted to solve problems for him as a father.

He sighed.

It's too big to stay in China.

While chatting, Li Shimin gradually talked about the topic he wanted to ask: "The store seems to have said that knowing all the conditions and collecting the right amount of data can make a reliable conclusion."

Yin Xuan nodded.

Li Shimin's eyes were slightly shining: "Then I wonder if it can be used for other things besides studying fireworks?"

Yin Xuan said: "Of course it is possible."

Li Shimin pretended to ask casually again: "Can it be used in the whole society?"

Yin Xuan nodded again.

"Then isn't this the Taoist deduction technique?" Li Shimin dipped some wine and wiped it lightly on the table.

Li Chunfeng said that he can know 500 years before and 500 years after.

But Li Shimin didn't believe it.

Arrange for him to go to Sitianjian to study astronomy and stars.

But the same words spewed out from Yin Xuan's mouth made him dubious, after all Yin Xuan didn't look like a ghostly person.
