Datang broom star

Wu Mei said stubbornly: "What are you afraid of? Talent is not determined by age. If you have talent, why don't you become a minister earlier?"

Jia Pingan hurriedly flicked for a while, and successfully made Sister take back this idea.

"By the way, when His Majesty mentioned the Shandong gentry yesterday, his tone was not friendly." Wu Mei felt that it was necessary to let the younger brother know the emperor's attitude, "He mentioned Lu Chengqing."

I go!

Lu Chengqing is a descendant of Fan Yang's Lu family. As Li Zhi's leader who was introduced to the court to deal with the eldest grandson Wuji's party, he will complete the task. Are you ready to kill the donkey?

The emperor is indeed a ruthless creature with a sword drawn. What kind of friendship, what kind of merit, when you threaten him and the country, these are all fake and empty, and you can change your face and deal with you with your backhand.

Wu Mei said indifferently: "Ping'an, do you know the dangers when His Majesty first came to the throne? At that time, Changsun Wuji and others controlled the government and threatened His Majesty. Your Majesty forbeared and pretended to be weak to confuse them.

He wanted to make a move, but he was alone and alone, so he pulled someone here and another person there, and gradually those people became his wings, and once he cut off the arms of the powerful ministers, he was in power... The hardships and sufferings of this journey have you covered... unimaginable. "

Isn't this tinker?Lee Ranieri Zhi.Knowing this kind of suffering, Jia Pingan spends every day in various calculations, fearing that if he makes a wrong move, he will fall into the abyss.

Li Zhi had a lot of white hairs on his head, most of which were the product of suffering... When the first emperor was seriously ill, he was anxious, worried that he would not be able to control Datang.

In fact, he really couldn't control Datang, and Changsun Wuji and his group became emperor instead of him.

Now the small circle is torn apart, the emperor seems to have won a big victory, but the Shandong gentry took advantage of the vacancy...

When I am a display?

Li Zhi probably wanted to mobilize the army at this moment to wipe out the Shandong gentry in one fell swoop.

Jia Ping'an then went to the prince.

"Brother." Cao Yingxiong also wanted to learn how to count and assist yesterday, but the crown prince went, so he could only squat here to check in.

"Yesterday, I only heard that my elder brother is majestic and majestic, and the overwhelmed Shandong celebrities can't raise their heads..."

Why am I pressing them?

Jia Pingan felt that the word was ambiguous.

"Who said that?"

"His Highness said."

Li Hong coughed dryly, "Uncle was so majestic yesterday."

You will be more majestic in the future.

Hao Mi looked at Jia Ping'an silently, knowing that his current knowledge is not qualified to help the husband, the only way is to study hard.

"Attend class!"

Jia Pingan sat opposite.

Li Hong raised his hand, "Uncle, I just want to take world class."

fart boy!

【Reading benefits】Follow the official account【】Read books to draw cash/point coins every day!

"Alright!"

Jia Pingan started class.

Zhao Erniang listened from the side.

What is World Class?

Is it interesting that the prince can't wait so much?

"...The world is very big, and Tang Dynasty is not small. For example, the north of Tang Dynasty is dry and rainy, while the south is rainy. How to deal with this situation? Currently, the best way is to build ditches, and we must pay attention to it. One... cut down the forest with as few trees as possible."

Li Hong was curious, "Why can't trees and forests be cut down?"

Zhao Erniang was also quite curious about how to answer this question, and stared at Jia Pingan quietly with her eyes.

"Trees and vegetation can hold water sources, rain falls from the sky, dead branches and fallen leaves on the ground can intercept the flow of rainwater, and the land with trees and vegetation has many gaps, and the rainwater soaks down along the gaps, and the water is retained , This is to conserve the water source. If the water source cannot be conserved, the sun will be exposed to the sun for a long time, and the water on the ground will be evaporated, so the land will dry up and the trees will die..."

"Is that so?"

Jia Pingan said with a smile: "The prince has nothing to do, so he can take someone to dig a tree. See if the water is trapped under the tree, making it more humid. Trees and vegetation have many functions. To put it simply, do you know about deserts?"

Everyone nodded, and Zhao Erniang couldn't help nodding along... This class is so interesting and lively, and it makes people suddenly enlightened... How is Mr. Wuyang so talented?

"The desert was not a desert in the past, and it used to be full of trees, but it gradually turned into a desert. In the north, those grasslands were herded by other races, and cattle and sheep gnawed on the grassland for years. Now it is raining, and the weeds are lost. The rainwater It hit the ground directly. The soil layer in the north is very thin..."

Jia Ping'an had been to the grassland back then, and the soil layer was really thin, and the sand layer was exposed in some places.

"Without trees and weeds to protect it, rainwater can wash away that layer of soil. Without the soil layer, weeds cannot grow, and the land becomes sandy land, which cannot hold rainwater. Then it dries more and more, and finally becomes It became a desert..."

Li Hong only felt that a door opened before him, allowing him to see a wider world.

"Uncle, I heard from them that the river turned yellow because the loess along the banks was washed down. Is this because there are no trees and weeds?"

The big river is the Yellow River of later generations.

Smart baby!

Jia Ping'an was excited... With such a smart prince, many things can continue to develop.

"This is the main reason. There is another problem. There will be more and more sediment, which will raise the river bed step by step, and finally the river will spread, and floods will become the norm along the river."

The Yellow River was still clear before the Tang Dynasty, but now it is turbid from time to time.

The forests in Guanzhong area have been felled for many years.Without the trees, the loess is not stable enough, and the rain and river water wash away to form the Yellow River.

Li Hong pondered.

Jia Ping pressed his hand, motioning everyone not to disturb his thoughts.

After a long time, Li Hong raised his head, "Then... you can't cut down on both sides of the big river, and anyone who dares to cut down will be severely punished."

Jia Ping'an smiled like an old father, "But the trees in other places have been cut down, and when the rain comes, the loess will rush into the river. This problem must be solved slowly, not overnight."

Guanzhong has been felled on a large scale since the Qin and Han Dynasties, and the ecosystem has been severely damaged.Let alone Datang.In the Song Dynasty, floods became the norm.This can also be said to be harming one's own family.

Li Hong looked solemn.

After class, Li Hong hurriedly took a few servants to the back.

"Where's the prince?"
