"Brother Prince, please speak." Li You said.

Li Chengqian said: "Fifth brother, there has been a big incident recently, and you don't know if you don't go to court, let me tell you......"

It turned out that it had not rained, and although the imperial court had taken measures to fight drought in advance, the lives of the people had been affected to a certain extent. Today's drought, combined with last year's floods, will inevitably cause panic and rumour.

The ancients were superstitious and thought that the successive floods and droughts were God's disgrace to the people of the Tang Dynasty. As the Son of Heaven, Li Shimin is not favored by God, which shows that his status is problematic in the eyes of God.

Under the deliberate rendering of people with intentions, it became a problem with the legitimacy of Li Shimin's identity as the Son of Heaven. In this way, an ordinary flood and drought disaster has become a political issue.

During this time, people everywhere spontaneously held large-scale rain prayer activities, and they carried the dragon king through the streets and alleys, which actually caused disturbance to the people. There have been many conflicts between the people and the government.

Li Shimin mobilized hundreds of civil and military officials to vigorously refute the rumors, but if it doesn't rain, you just wear out your mouth, and the people don't believe it.

In the court, a group of ministers represented by Xiao Qian all asked Li Shimin to take the lead in begging for rain.

Li Shimin is on fire, even if he eats ice cream and ice cream, it doesn't work.

These days, the sunny weather was originally the object of poetry and eulogy, but now it has become a heavy stone in Li Shimin's heart, and it has become a dark cloud hanging over the imperial court.

At dinner yesterday, Li Shimin had a bad appetite and didn't have the heart to eat, so after eating a few bites, he asked the eunuchs to withdraw.

When a little eunuch was packing up his things, he hurriedly threw a plate on the ground and splashed some water on the ground.

If this were normal, Li Shimin would laugh and laugh. However, Li Shimin was troubled and was thinking about venting, so he immediately ordered the little eunuch to be killed.

Li Chengqian is a filial son, and when he saw Li Shimin so troubled, he wanted to help him solve the problem. So I came to Li You.

Li You didn't want to be nosy, he just wanted to live a small life in his own one-third of an acre and be a foodie quietly. However, this is the matter of his father and the prince's brother, no matter if it doesn't work.

He thought for a while and said, "Big brother, don't worry, this matter is a bit difficult, but it's not impossible." In this way, you go back first, and your brother will give you a letter tomorrow. ”

Li Chengqian went back in disbelief.

After Li Chengqian left, Li You called Zhao Fu. Li You took a drawing and asked Zhao Fu to process it.

Soon after, Zhao Fu brought a one-foot-long triangular ruler with fine angle lines engraved on it.

In the evening, Li Chunfeng, who was studying arithmetic in Qin Tianjian, received a message from Li You, saying that he wanted to tell him a new arithmetic formula, and he immediately went out and rode straight to the palace of King Qi.

Li You told Li Chunfeng about the Pythagorean theorem, and he was very patient today, carefully explaining the theorems and applications of the Pythagorean theorem to Li Chunfeng.

Then, Li You invited Li Chunfeng to dinner.

Li Chunfeng is a smart person, and while he was excited, he felt that the prince was a little abnormal today, so he took the initiative to ask: "Your Highness, have you encountered anything difficult?"

If there's anything you need to do, just ask. ”

Li You likes smart people, and he smiled: "Yes, Daochang Li, let me ask you a question first."

The Dragon King is the god of your Taoism, and legend has it that he can walk in the clouds and rain, but I don't know if the spirit is spiritual? ”

Li Chunfeng said: "Sincerity is spirituality. ”

"Okay, let me ask you again, is the purpose of Taoism to educate the people of the world and save the people from fire and water?" Li You asked.

"This is natural." Li Chunfeng replied.

Li You then asked: "In order to save the people from fire and water, is Daochang Li willing to contribute?" ”

Li Chunfeng puffed up his chest and said with righteousness and awe: "If you have any send, please ask Your Highness to command." ”

Li You stretched out his thumb and praised: "Li Daozong Dao bone fairy style, save the country and save the people, and really have the style of an immortal family." ”

Li Chunfeng said modestly: "Your Highness has praised it. Let's guess what His Highness wants Xiaodao to do, is it related to asking for rain? ”

Recently, the cause of the gossip between the government and the opposition is naturally known to Li Chunfeng. This long-lasting drought made Li Chunfeng very anxious.

He observed the heavens every day, hoping to see that it would rain, but there was no sign of rain, which made it difficult for him, the head of the Qin Tianjian, to sleep.

Li You said: "Yes, Daochang Li is really wise. What the people need most now is a rain, and what the court needs most is also a rain. Why don't you do something for the world? ”

"Your Highness, do you mean to let the ministers come out and ask for rain?" Li Chunfeng said.

"Yes, as the supervisor of Qin Tianjian and the Taoist chief, you take the lead in praying for rain, which has a great effect on calming the people's hearts." Li You said.

Li Chunfeng said: "Your Highness, the minister is willing to do this, but have you ever thought about it, if the minister can't ask for rain, will it cause even greater panic?"

Don't hide it from Your Highness, Your Majesty has already summoned the minister, and he wants to take the lead in asking for rain, but the minister observes the celestial phenomena and it will not rain recently, so he advises His Majesty not to do this.

If Your Majesty personally asks for rain, and the sky still doesn't rain, won't the world be in chaos? This is not possible! ”

Li Chunfeng shook his head vigorously.

Li You asked: "Otherwise, I watched the sky at night and found that there will be a great turn for the better in the near future, if nothing else, on the 29th of this month, there will be a heavy rain, and then it will enter the rainy weather." ”

Li You had already consulted the local chronicles of the Guanzhong area during the Zhenguan period, which recorded the date of the end of the great drought on the 29th of this month.

Li Chunfeng was a little unconvinced, he had been engaged in meteorological observation for so many years and had rich experience, he couldn't see any signs of rain in the near future, and he didn't know how Li You saw it.

Seeing that Li Chunfeng was silent, Li You smiled and said, "Daochang Li, can't you trust me?" You won't, I don't. It's like a one-dimensional equation, I don't teach you, will you?

Besides, what am I doing that is not reliable? ”

The current Li Chunfeng admires Li You so much that he throws himself to the ground. His Royal Highness King Qi, whether it is poetry, arithmetic, food or military affairs, which one is not done beautifully? !

He said: "Your Highness's talent, submit to it. Whatever His Highness commands, the minister will definitely do. ”

Li You said something to Li Chunfeng, and Li Chunfeng replied angrily: "The minister is willing, even if he is broken!"

"Good, good. It is worthy of Daochang Li, who has a fairy style and an immortal spirit. Li You praised from the bottom of his heart.
