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

The man gave Yin Xuan a deep look.

A person's strength is generally equated with his physique. He is as thin as a tuberculosis, but he can wield a pair of [-]-jin hammers. That is a character that can only appear in novels.

This unremarkable restaurant owner is really hiding something deep.

Li Shu has already asked: "Shopkeeper, how did you do it?"

"How did my little sister lift such a big rock?"

Yin Xuan pulled the paper on the table and began to explain to them.

"This is using the knowledge you think is useless." Yin Xuan shook his head and said softly, "You have read the Mojing, so you should know the principle of leverage?"

As he spoke, Yin Xuan drew a line on the paper, and then drew a fulcrum.
Li Shu listened with gusto.

Yin Lulu and Li Lizhi, including Jiu'er, who were not very fond of studying, all turned their heads to listen to Yin Xuan's explanation.

Starting from the principle of leverage, to the fixed pulley, movable pulley, and pulley block behind.

Yin Xuan kept talking until noon, when Li Lizhi's stomach started to growl, and then he said almost the same thing.

Li Shu's eyes were a little dazed, but she had some basics and didn't fully understand, but there were some thoughts of her own in it.

The remaining three little girls are completely at a loss.

Staring at the word "force" that is full of paper, I feel that this word is strange.

"Okay, I'll cook, what are you going to eat?" Yin Xuan stood up and asked with a smile.

Li Lizhi raised her hand high: "I want three delicacies from the ground, green pepper meat, and a piece of gold inlaid jade, and two bowls of rice."

Yin Xuan nodded.

He just raised his foot and walked a few steps towards the kitchen, when he suddenly turned around.

"By the way, it's just meaningless to say dryly, let's assign you a homework."

"It is known that the weight of that piece of bluestone is [-] catties, and Lulu's strength is about [-] catties. Please draw how the pulley block is composed."

Except for Li Shu, the remaining three little girls complained mournfully.

"Brother, didn't you say you don't have to study this afternoon?" This is Yin Lulu, looking at Yin Xuan pitifully.

"Why do I have to draw?" At this moment, Li Lizhi covered her chest, feeling as if she was innocently lying on the knife.

Jiu'er didn't speak, but there was some resentment in her eyes.

While taking the ladder, Yin Xuan took off the pulley block: "I don't ask you to make it this afternoon, I give you three days."

"Come on girls!"

At this time, I can no longer see the excitement they had when they first came into contact with pinhole imaging yesterday.

Li Shu tightened her palms, and while they were not paying attention, carefully put away Yin Xuan's writing and drawing papers - in her opinion, it was no less a treasure than Mo Jing.

Imperial City East Palace.

Li Shimin narrowed his eyes and looked at Zhichang, who was bowing to the right prison gate in front of him, and frowned slightly: "It's really nonsense, she is fooling around, and you are fooling around too!"

Li Shu asked him to compete with Yin Lulu, of course, he dared not keep it a secret. After Li Shimin returned, he immediately reported it to Li Shimin when he left the court.

This somewhat made Li Shimin a little unhappy.

Public is public, private is private.

Using public power in private matters is somewhat overstepping.

The matter of Zhou Youwang's Fenghuo drama with the princes was placed on Li Shimin's desk, and he was always alert to himself to restrain his inflated heart and power.

How did a dynasty fall?
Since he couldn't control his own desires, King You of Zhou was like this, and so was the former Sui Dynasty. Those bloody precedents were right in front of his eyes.

"The princess is still young." Zhichang, the right prison gate, said in a low voice.

Li Shimin waved his hand: "When she comes back, I will naturally educate her well."

After speaking, he paused for a moment: "But you said that you lost to a seven-year-old girl. Is this true?"

The right guard had a shameful expression on his face: "Yes, although the little girl used some tricks, but if I lose, I lose."

As he said that, he remembered something, and continued: "Your Majesty, I also discovered that the owner of the Tongfu restaurant has a lot of strength."

"The boulder that I took so much effort to lift looked as light as a feather in the hands of the shopkeeper."

Li Shimin was a little surprised.

Another new advantage.

This reminded him of something that Cheng Yaojin told him. He said that Yin Xuan is a man who strikes steadily and ruthlessly. The embryo will be fierce.

Hungry!

Li Shimin was really hungry.

There is indeed no shortage of good ministers and generals under him, but they are all a little too old. Among the younger generation, there are few who can be as good as their parents.

It would be nice if this man could use it for himself.

Li Shimin sighed, and gritted his teeth. It seems that he has to work harder, just like Liu Bei's three visits to the thatched cottage. Don't you believe that you are not as good as Liu Bei?
"Do you know how he did it?" Li Shimin asked enthusiastically, "What method did he use?"

Zhichang on the right prison door pursed his lips, shook his head and said: "I listened for a while, and found that what I said were words that I couldn't understand."

"What kind of arm, what kind of strength. I can't understand it, and I can't neglect my duties for too long, and I will come back. The shopkeeper said it, but I don't know."

arm?force?

Li Shimin was also a little dazed. These two words were things he couldn't understand.

"The two princesses Changle and Lanling are learning from him?" Li Shimin asked seriously.

The right prison door nodded straight.

Li Shimin said: "Then I'll ask them when they come back."

The sky gradually dimmed.

Two princesses with little turtle faces came back from the Tongfu restaurant. Li Lizhi clenched her fists and muttered in a low voice: "Sister, let me tell you, I'm really unlucky today!"

"I only took a few Wang Bo, and there are not many bombs."

"When luck improves tomorrow, I will definitely win back hard."

Li Shu chuckled and didn't express any opinion.

The four of them played poker. Naturally, they played the rules of Four Players Fighting the Landlord. There was not much change with the Three Players Fighting the Landlord. It was just that the chances of being teammates with Li Lizhi increased.

As for the bad luck talk
Li Shu doesn't think it's bad luck to have at least one bomb in every hand.

She is curious about two things now.

One is how the pulley block was assembled, and the other is how my sister was able to lose in all kinds of weird and unexpected ways.

When they arrived at the palace, the two of them just got off the carriage.

A court lady was here early.

Seeing Li Lizhi and Li Shu get off the carriage, the palace lady went up to welcome her: "His Royal Highness Princess Lanling, Your Majesty, please go over there."

Li Shu's heart skipped a beat, and she had a bad premonition.
