When Yang Wenhua said that he would rely on the thousands of caravans of the Cui family on his own, he drove Goguryeo out of Liaodong.

While making the ministers in an uproar, it also aroused the hostility of some well-intentioned people.

Li Shimin, who was high in His Majesty, was startled at first, and after looking at the expressions of several members of the Zheng family, his eyes froze, and he asked: "A few Zheng Qing families, do you have any misunderstanding with Master Sanzang, can you say it, and let me mediate for you." ”

Zheng Shan grabbed his brother's wrist and went out of class to play: "It's just a little thing, don't dare to bother the saint to ask." ”

Zheng Shan's words made Li Shimin almost vomit blood, and his disgust for the family suddenly increased a little more.

Yang Wenhua looked at the few people who were still sneering at him, and secretly remembered the appearance of a few people in his heart, the Zheng family with five surnames and seven sects?

Let's have fun.

There is a problem here, everyone in the hall looks like they are watching a good show, a five-surname and seven sects, a mysterious and bold Donggui monk, and then there will be a big drama to watch.

At this time, the sound of horses' hooves was heard outside, interrupting the strange atmosphere in the hall.

After a while, the military general who had just left walked in with Yang Wenhua's jujube red horse, saluted Li Shimin, and replied:

"Holy Lord, there is iron on this horse's hooves, and walking on ordinary rocks is almost like walking on the ground, and the iron on the hooves is really exquisite."

Before everyone in the palace could express their opinions, several attendants hurriedly walked in with a Quyuan plow, and one of them reported to Li Shimin:

"Holy Lord, this plough is really easy to use, only a ploughing ox can be dragged this plough to walk like flying, and the field of the plough is deeper than the straight plow."

"Okay, hahaha, that's good."

With two pieces of good news in a row, Li Shimin was pleasantly surprised, and everyone in the hall also started to talk about it, and looking at Yang Wenhua's eyes, it was suddenly very different.

If the people in the hall still had some contempt and suspicion for Yang Wenhua at the beginning, it would have become an expectation at this moment.

Of course, the faces of the Zheng family became a little more ugly at this moment.

Before everyone could sigh anything, two more groups of attendants carried two sand tables into the main hall, and everyone looked at them curiously.

The two sand tables are composed of some undulating terrain and a ditch in the middle, which is relatively simple due to the rush of time.

The difference is that one sand table is covered with turf, while the other is just simple yellow mud.

In the curious eyes of everyone, Yang Wenhua bowed to Li Shimin and said: "If the saint wants to control the water, he must first know where the flood came from.

This thing, the poor monk called the sand table, it can not only let everyone have an intuitive understanding of the terrain, can be used for marching formation, but also let everyone understand the formation of floods. ”

"Then ask the master to explain a thing or two to me."

After getting Li Shimin's permission, under Yang Wenhua's instructions, several attendants began to use bamboo tubes to absorb water and spray it on the top of the two sand tables.

The atomized water vapor fell on the sand table, and after a while, the ditch in the middle of the sand table began to accumulate water and flow down the gap.

The two-meter-square sand table, after spraying two buckets of water, the two sand tables have already shown the doorway.

There is a sand table covered with turf, which is basically unchanged, and the water that flows out is relatively clear.

The water flowing out of the sand table without turf is very turbid, and not only the level of the sand table has become a little shorter, but the ditch in the middle has changed significantly.

There have been some noticeable collapses along the entire section of the ditch, the front section is better, and the latter section of the ditch has been silted.

Soon after the water spraying continued, the sand table without turf was severely silted up, and large craters appeared in some places, and the flooding began due to the poor flow of water.

With such an intuitive presentation, the people in the hall naturally got an intuitive understanding.

"Everybody's got it, right?"

After Yang Wenhua smiled, he stepped forward to change the sand table with turf, and made a few big pits in the upper class.

"As long as the vegetation along the river is flourishing, then flooding is not easy to occur, and combing the river can also get twice the result with half the effort.

If some reservoirs are built upstream, water can be stored in times of flooding, not only so that the downstream can quickly flood when there is widespread rainfall, but also allow the stored water to be used in times of drought. ”

On the side covered by turf, with a few large pits in front of it, the water flow in the ditch will naturally become smaller as the water continues to be sprayed.

Facts have proved that Yang Wenhua's words are correct.

In the future, as long as we act according to this theory, even if there is still a flood, it will no longer be too much of a problem.

With such an obvious answer, everyone naturally admires Yang Wenhua a lot.

Li Shimin was even more happy and applauded, "Okay, hahaha, the master is really a scholar of heaven and man, not only is he skilled, but this teacher is the way of heaven and earth, and the way of nature is even more wonderful." ”

"Hmph, although I have some ability, but with this way of controlling water, I can call it a natural teacher, and I'm afraid that my tone will inevitably be bigger."

Just when everyone in the hall was overjoyed, a shrill voice came out from the hall.

Yang Wenhua looked at the person who spoke, and suddenly a cold light flashed in his eyes, "I don't know who this adult is, and who is he more proficient in?" ”

"Old man Zheng Shan, as for being proficient, although the old man is not talented, he still has some experience in governing Confucianism, astronomy, and governing places, I don't know what Master Sanzang has to say?"

Looking at this thin middle-aged man, Yang Wenhua smiled disdainfully, "If I say that there will be a big drought in Guanzhong this year, accompanied by a plague of locusts, I don't know what Lord Zheng Shan, who is proficient in astronomy, Confucianism and local governance, will think and what will he do?" ”

"Joke, if you say there is a drought, there will be a drought, and if you say there is a locust plague, there will be a locust plague?" Zheng Shan immediately sneered.

As soon as Yang Wenhua's words came out, most of the people in the hall disagreed, but some were worried.

Li Shimin's heart tightened, he didn't care about Zheng Shan's words, and hurriedly asked Yang Wenhua: "How did the master know that there will be a drought and locust plague in Guanzhong this year?" ”

"It is also the way of heaven and earth."

Yang Wenhua smiled confidently, "This year's century-old trees in Guanzhong have sprouted much worse than in previous years, telling the poor monks that there will be a drought in Guanzhong."

This year, there is little snow in Guanzhong, and the land turned out, with many insect eggs in it, coupled with the drought, tells the poor monks that there will be a locust plague in Guanzhong. ”

Li Shimin asked with some hesitation: "Is the master's way of nature accurate?" ”

"Everything in the world has traces to follow, just as when plants and trees disappear, there will be floods.

The hundred-year-old tree sprouted less than in previous years, naturally because it felt that there would be a big drought this year, so it sprouted less out of self-preservation.

Last year, there was little snow, so the eggs did not freeze to death in the ground, and the drought and locusts did not eat much, so they naturally gathered into a locust plague. ”
