The first pavilion of the second mountain passed, and Xiao Yuan received the baptism of holy light for the fourth time, and then stepped into the second pavilion of the second mountain.

Xiao Yuan walked up slowly, only to see that "Nong" suddenly flashed in the pavilion - a big golden character, and then the cyan slate in the pavilion emitted small golden characters: Loess Plateau, why are the low mountains and hills highly productive?

Xiao Yuan looked confused, and said in his heart, isn't this a geography question in elementary school? Forget it, don't think about it so much. I'm still honest with my questions. Go to the mountain of books. ”

Why is the Loess Plateau highly productive?

Xiao Yuan slowly pulled out the pen, stained with thick ink, and wrote:

(1) Natural causes: loose loess soil and vertical joint development; Monsoon climate, concentrated precipitation, heavy rainfall.

(2) Human causes: destruction of vegetation; unreasonable farming systems; Mining.

Xiao Yuan thought about it, and he could make some additions and improvements. Then he wrote:

Governance measures: reduce agricultural land and expand the area of forest and grass planting; Reforestation; Comprehensive management of small watersheds (example: Nanxiaohegou in Gansu Province). Causes: Shortage of energy in rural areas.

Remediation measures: the development of three-dimensional agriculture. Solve the problem of farmers' daily energy consumption (vigorously promote domestic coal;) Technological innovation of stoves; biogas and fast-growing charcoal forests).

Unfortunately, the old man reappeared, and Fusu asked, "How can you come up with such a solution?"

In fact, a saint has already made this statement. Xiao Yuan put away the pen and lifted the inkstone.

"Oh, tell me about it?"

"In the Yaoshun era, China has begun to build water conservancy, at that time people have understood and used water conservancy to develop agriculture and irrigate the countryside. After the Yuping water and soil, China's economy entered the agricultural era, and then went through the geography, so that all parts of the country can enjoy the benefits of river irrigation. Zhou Li recorded: "There is a sui between the husbands, ten husbands have ditches, a hundred husbands have a river, a thousand husbands have a mud, and ten thousand husbands have a river." Then it was injected into the ditch, and the ditch was injected

洫, 洫 injected into 浍, 浍 injected ) I|. Therefore, the water of the acres of land has returned. This shows that the irrigation and drainage system at that time was developed and the people benefited.

In the Spring and Autumn Period and the Warring States Period, people had a better understanding of the relationship between water conservancy and agriculture. In the book "Guanzi", it is emphasized that the officials in charge of agriculture must assume the responsibility of building water conservancy, "so that although the water is excessive, it is harmless to the grains, and although the year is fierce, there is something to be gained." By this time, people had also learned to build large-scale specialized irrigation projects. According to the records of historical books, the Ximen Leopard of the Wei State and the Zhangshui Canal of the Shi Qi, and the Zheng built by the Qin State

The national canals were all famous canals at that time, with an irrigation area of tens of thousands of hectares. "Notes on the Book of Water" recorded: "King Qin Zhao made Li Bing to guard Shu, opened two rivers, and irrigated thousands of hectares of fields. "What is written here is about Li Bing's father and son building water. ”

Then Xiao Yuan spoke to the old man in detail, and it took half an hour to explain clearly.

The old man nodded, asked the drunken eyebrows, and said, "The son can be taught, and the three mountains will meet again." As soon as the words fell, they turned into an ink shadow and disappeared between heaven and earth.

Xiao Yuan fell a stone in his heart, and sighed slightly: "It seems that we will have to be more restrained in the future." ”

After answering, Xiao Yuan walked towards the third pavilion.

The plaque on the third pavilion of the second mountain reads Holy Works.

This time, the old man did not appear, but a test paper appeared differently than before.

The examination papers are respectively about the smelting of weapons, the planting and harvesting of crops, and the very remote water conservancy projects.

Xiao Yuan didn't know anything about the three aspects, but fortunately, he had the heart of Wenqu, and he gave the answer seriously.

Xiao Yuan officially crossed the second mountain. It seems simple, but in fact it is far more difficult than the first mountain.

After receiving the baptism of holy light in the third pavilion of the second mountain, Xiao Yuan glanced back, and only one person appeared in the first pavilion of the second mountain.

"This time, except for me, I'm afraid that everyone will not be able to pass the second mountain, this year's exam questions are too biased, and I suspect that those Jinshi Hanlin may not be able to answer correctly. ”

Xiao Yuan looked at the black crowd at the bottom of the mountain, thinking that everyone would be told by the demi-saint what position they were in after leaving the Book Mountain, more than half of the people could enter the first pavilion of the book mountain before, and there were many people who passed the first pavilion of the book mountain, but now and there was no comparison with the past, so everyone deduced that this year's book mountain was too difficult.

Xiao Yuan walked towards the third mountain, while recalling that the first mountain test characters, couplets, and dictation were all literature, but they were different from ordinary exams, and the second mountain was all acrobatics.

"I don't know what to test in the third mountain. ”

Xiao Yuan went down the second mountain and encountered a more violent wind, this time his clothes were blown slightly by the strange wind.

Walking to the first pavilion of the third mountain, Xiao Yuan saw a very high wooden pole standing in the middle of the square, and the word "Qiao" was written on the plaque.

A ruler appeared in Xiao Yuan's hand, and the old man's voice then appeared: "Use a ruler to measure the height of the wooden pole." ”

Xiao Yuan was stunned for a moment, thinking to himself that this was practicing climbing skills? However, when he tried it, he found that there was something wrong with the wooden pole, and there was a strong force that prevented him from climbing.

Xiao Yuan took the ruler and looked around, and soon found that he and the long wooden pole had left a shadow on the ground, and after a little thought, he smiled.

"At the same time, the ratio of the ruler and the long rod to its shadow is equal. The height of the long pole can be calculated by standing the ruler on the ground, measuring the length of the ruler and the shadow of the ruler in a short time, and then measuring the length of the shadow of the wooden pole. ”

"If you don't go through the systematic learning on the earth and only receive the education of the Holy Yuan Continent, even those so-called half-saint disciples may not be able to come up with a measurement method. It's not that they're not as smart as me, it's that they don't think as well as mine. ”

After Xiao Yuan finished thinking about it, he began to measure it manually, and finally got the correct length, and successfully obtained the holy light baptism of the first pavilion of the third mountain.

This time, the baptism of the Holy Light lasted for an exceptionally long time, which made Xiao Yuan's strength make great progress.

When he saw Xiao Yuan leaving the first pavilion of the third mountain, the Wei State Tongsheng under the mountain let out a hoarse shout.

The two national talents of Wu and Tang were silent, but more than half of them bowed their hands to Xiao Yuan, expressing their joy and sincerity. Some people didn't care about Xiao Yuan's victory or defeat, but seeing the reactions of some of the talents of Wu Guo and Tang Guo, their eyes became strange.

Several older Wei Guoxiu found out about this scene and was extremely excited.

Wu and Tang joined forces to suppress Wei Jiangnan for decades, causing almost irreparable damage to Wei's literary name and popular hearts, coupled with Wei's serious injuries and defeat sixteen years ago, many literati and people expressed their attachment to Wu or Tang.

Neither Wei Jianshu nor the Great Confucian Right Minister could reverse the situation, and could only watch the Chinese people being despised by outsiders.

But now, Xiao Yuan used his strength to climb two mountains and go to the Seven Pavilions. Let the children of Wu and Tang convince them, and if they recognize Xiao Yuanyun, they will recognize the scholars in Jiangnan, which is equivalent to recognizing the power of Wei.

Many of the children present were full of admiration for Xiao Yuan, and after leaving Shushan, today's memories do not exist, but their subconscious good impression of Xiao Yuan is still retained.

This seemingly inconsequential change has great significance, which means that the efforts of Wu and Tang for decades are being slowly resolved by Xiao Yuan on his own, which is something that no one in the Wei State can do.

The other nine kingdoms may sympathize with Wei, and even respect Wei to fight to the death with Long Ling, but when there is a conflict of interest with Wei, sympathy and respect will become worthless, and strength and power can decide everything - it is always the power that comes out of the barrel of a gun.

Without enough hard power, all soft power is in vain, and it will be broken at the first poke.

Xiao Yuan is improving the hard power of Wei step by step.

Everyone watched Xiao Yuan slowly walk to the Second Pavilion of the Three Mountains, although they didn't know what the Second Pavilion was examining, but everyone knew that the Second Pavilion of the Third Mountain was very important, because anyone who passed the Second Pavilion of the Third Mountain when he was a child would have great achievements in the future.

Whether or not you can pass the second cabinet determines whether a person is a genius or not.

Xiao Yuan slowly entered the second pavilion of the third mountain, and found that he was in a school field, and there were many weapons in the school field.

"Could it be that this second pavilion is the place to test martial arts?"

The old man came out again and said, "You can choose any weapon." ”

"Yes. Xiao Yuan chose a plain sword, and then a spirit soldier appeared in front of him.

These spirit soldiers are all well-trained, but Fang Yun has also seen Xiao Yuanshan kill the spirit clan, only to see that Xiao Gongzi's sword shadow and moon dance, in a sword light, the spirit clan died one after another, and finally Xiao Gongzi achieved excellent results.

After completing the exam of the second pavilion of the third mountain, Xiao Gongzi turned his head to look at the bottom of the mountain.

The people of Wei let out an earth-shattering cheer.

After the real Third Mountain Second Pavilion, after stepping into the Third Pavilion, no matter whether he succeeds or fails, Xiao Gongzi will be highly praised like those geniuses.

If he can really break through the three mountains and three pavilions, then Xiao Gongzi will become the first child in history to climb the fourth mountain - the person who has obtained the heart of Wen.
