Datang: The Craziest Scholar System

"Well, it's delicious."

Su Yun smiled and took a bite.

"But it's worse than the glutinous rice balls you made, son, um...not as good as mooncakes...and..."

As Hongdou talked, she announced the name of the dish.

Behind him, Li Shimin was dumbfounded.

What's happening here?
Why do you still hate it?
Didn't you say it was delicious before?

More importantly, why did he give Su Yun the red beans, which he specially brought out for his daughter from the imperial dining room?
When did the girl put it in her arms?

And shouldn't you ask me the principle and drawings?

A series of questions floated through my mind, and His Majesty Li Er was in a bad mood.

He felt bitter, this was his own daughter.

Why do you always favor that bastard Su Yun?
And feed him pastries yourself?

At this moment, he saw Su Yun walking towards him with a watering can in his hand.

Anyway, he is the emperor, Li Shimin sorted out his emotions in an instant.

However, before he opened his mouth to speak, he heard Su Yun say: "I heard that you caused trouble outside?"

His Majesty Li Er was taken aback, "No."

Su Yun gave him a meaningful look, "It's fine if you don't have one. Be careful with your words and deeds outside, and don't offend people you can't afford."

Li Shimin suddenly remembered something.

That day he left the address of Zhangjiacun, which attracted the assassin of Wannian county magistrate, but in the end the assassin seemed to be killed by the boy?

While thinking about it, Su Yun's voice sounded again.

"Well, after all, you are working here for me. If you encounter something you can't solve, you can hide here for a while."

His Majesty Li Er was stunned.

Is Su Yun caring about him?
Several of them have witnessed Su Yun's fighting power with their own eyes.

If he hides here with Su Yun, no matter how powerful an assassin is, it will be useless.

This boy... really has a cold face and a warm heart!

Li Shimin was actually a little moved.

"What are you thinking? If you want to do business, just listen to me! You told me all about your thoughts."

Su Yun said lightly, and broke the watering can into some broken parts casually.

Yuan Tiangang and Changsun Wuji were dumbfounded.

That's made of iron, can you break it open with bare hands? !
Su Yun ignored their surprise and began to explain.

"This watering can uses the principle of pressure. When the pressure increases, the water will be squeezed out, and then through the specially made nozzle, the water will appear in the form of mist, which can greatly improve the use of water when watering. Rate."

"Specifically, the watering can is divided into seven parts: the nozzle, the mixing chamber, the switch, the handle, the body of the pot, the air pump, and the liquid outlet pipe. Among them, the nozzle and the air pump are the most important parts... Do you understand?"

After an explanation, Su Yun looked at His Majesty Li Er and the three of them.

The three of them looked at each other, and they all saw the confusion in each other's eyes.

What pressure?
What mixing chamber?

What pump?
? ? ? ? ?

"Understood!"

But the little girl Hongdou answered positively.

Su Yun glanced at Hong Dou in relief, then turned to teach Li Shimin and the others a lesson:

"Do you know the difference between people? Why do you work, and Hongdou hires you to work?"

The faces of His Majesty Li Er and the three of them turned red and turned white.

The meaning of this sentence is, look at you, three old men are not as good as a little girl!
Su Yun shook his head, "Third watch and five watch chickens are the time for men to study. The black hair doesn't know how to study early, and Bai Shoufang regrets studying late."

"Let you not study hard when you were young, do you regret it now?"

Hong Dou grinned and made up the knife: "The opportunity to make money is right in front of you, you don't understand, who is to blame?"

Being teased by Hongdou, Li Shimin and the others blushed.

Changsun Wuji silently took out a pen and paper, and wrote down the poem Su Yun said...

He didn't want to remember it at first, after all, it was used to teach the three of them a lesson.

But this poem is so good, enough to be sung through the ages...

"Forget it, I didn't expect you to understand. Let me draw a blueprint for you."

Su Yun sighed, it was not normal for Li Shimin to understand.

In fact, this is the sprinkler irrigation technology commonly used by later generations, but it was used by Su Yun in the Tang Dynasty in advance.

As for the principle, anyone who has studied pressure can understand it all.

However, in the eyes of Li Shimin and the others, it was already incomprehensible.

But this does not conflict with Su Yun reprimanding them.

His Majesty Li Er, Sun Wuji, the Duke of Zhao, Yuan Tiangang, No. 1 of the Taishi Bureau, and several bigwigs in the dynasty were obediently like babies, listening to Su Yun's teachings.

After all, they were also taught by tutors, and it was their fault that they didn't understand... What's more, they were counting on Su Yun's blueprints.

Looking at Hongdou, they quickly understood, and they also had some doubts. Could it be that they are really stupid?

Of course, if they knew that Hongdou was instilled with modern physics knowledge by Su Yun since childhood, they would not think so...

"Red beans, pen, ink, paper and inkstone are waiting for you."

While splashing ink, Su Yun carefully drew the schematic diagram of the watering can, and threw it to Yuan Tiangang casually.

The principle diagram drawn by Su Yun is clear and easy to understand, anyone with a little forging foundation can understand it.

Yuan Tiangang held it in his hand as if it were a treasure, and tremblingly said: "It's amazing, it's really amazing! I'm really convinced!"

After seeing the schematic diagram clearly, he really understood how advanced vision is needed to invent this watering can!

Coupled with Su Yun's accurate prediction of the severe drought and his daring to insult His Majesty Li Er many times, Yuan Tiangang regarded Su Yun as a god for a while.

His Majesty Li Er left contentedly. Before leaving, he did not forget to promise that he would bring delicious food to Hongdou next time.

Hong Dou told him not to forget to bring the dividend money, and His Majesty Li Er finally left feeling frustrated.

"My lord, do you think the watering can will sell well?"

Seeing the backs of the two leaving, Hongdou asked curiously.

"As long as there are no accidents, it will definitely sell well."

Su Yun said.

The watering can is a sharp tool to deal with severe drought, and it will definitely sell well when it appears in this era.

"Accident? What will happen?"

Hongdou tilted her head, puzzled.

"The appearance of something that can be sold in this way represents a profit."

Su Yun explained, "Everyone is innocent, but pregnant is guilty."

Such benefits must bring jealousy.

"Sir, do you mean that someone will take Lao Li's idea?"

Hongdou frowned beautifully.

Su Yun nodded, "I even suspect that the killer last time was because Lao Li exposed Qu Yuanli!"

"So it is!"

Hong Dou suddenly realized, "Brother Su Yun, so you don't want to give Old Li Quyuanli and the watering can, to some extent you are protecting him!"

"Don't talk nonsense, I didn't."

Su Yun directly denied it.

"Hee hee, you have!"

"I do not have……"

"You have it, you have it, you just have it!"

Hong Dou said with a smile: "I knew that the young master is the kindest!"

Su Yun supported his forehead, and helplessly stroked Hongdou's beautiful hair.

While the two were talking, the old butler came in from the outside leaning on a cane.

"Young Master, Miss, there is some commotion outside the village, I don't know what happened."
