Zhao Tian looked at Zhao Wei, and his eyes flashed with wisdom:

"Taihang an embankment, has a history of more than 100 years, although the imperial court and the local government allocate funds every year to strengthen and repair, but do not change the fact that it has been a long time, the internal structure of the embankment has been full of holes, the equipment is aging, the embankment has also partially subsided, and this year's rain is menacing, I am afraid that this embankment is more auspicious and less auspicious......"

Zhao Tian sighed as he spoke, and the people around him were all frightened and nervous after hearing Zhao Tian's words.

But only Zhao Wei stood still, looking at Zhao Tian happily, he knew that this daughter thought so much, there should be a solution.

"Alas......" Zhao tilted and pointed to the embankment, looked at the churning river, and slowly said three words: "Du~Jiang~Weir!" ”

"Huh!?" The people next to him couldn't help but wonder, what is Dujiangyan?!

This Dujiangyan may be among the people, only Zhao Tian knows what it is! In this era, there is no such thing as Dujiangyan.

The Dujiangyan Water Conservancy Project is located at the western edge of the Chengdu Plain, where the Minjiang River enters the plain from the valley. Before the construction of Dujiangyan, the water of the Minjiang River rushed into the plain in the rainy season and often flooded; When there is not enough rain, it can cause drought. In order to turn harm into benefit, Li Bing, the Taishou of Shu County of Qin, presided over the construction of the Dujiangyan Water Conservancy Project.

The topography of the Taihang River is no different from that of the Minjiang River, which spans two different natural geographical areas in the Taihang Plain and the Dumen Mountain area, and the geomorphological unit belongs to the first-class terraces of the alluvial fan of the Minjiang River. The terrain is high in the northwest, low in the southeast, high mountains, middle mountains, low mountains, hills and plains are distributed in steps, and the principle of Dujiangyan is used to use it, which is a wonderful way!

Zhao Tian clapped his hands: "Pick up this embankment!" ”

"Pickpocketed?!" When the people around heard this, they were shocked!

The people around him began to talk in private again, but they didn't dare to say it out loud......

At this moment, Zhao Wei was also very puzzled, and his eyes were full of puzzlement.

Zhao Tian didn't have time to explain more, so he asked the prefect to go to the upper reaches of the Taihe River with a group of people, and dig a hole in the embankment of the Taihe River ten miles away from here, as soon as possible.

The prefect looked at Zhao Wei, Zhao Wei looked at Zhao Tian's firm eyes, and nodded to the prefect: "Do it!" ”

As he spoke, the prefect waved his hand, and a group of officials followed behind.

"Alas! Wait! Zhao Tian stopped them.

The prefect was taken aback, did he do something wrong again!?

Zhao Qian reminded: "This opening can't be too big or too small, the depth of one person, the width of two people, try to open as many as possible!" ”

The rain poured all over the sky, and the raindrops hit Zhao Tian's oil-paper umbrella, crackling, and I felt that the heavens didn't want to keep it at all!

The pressure on the Taihang embankment is also increasing, and there is an endless stream of people carrying tools, and the heads are moving, and the work is in full swing!

"Oh no! My lord. Suddenly, a guard came, and was about to salute, but was pulled up by Zhao Wei.

"In extraordinary times, there is no need to be polite!" Zhao Wei gently lifted the guard.

The guard anxiously pointed not far ahead: "There is a landslide at the embankment ahead!" ”

Zhao Wei ran quickly in small steps, and immediately followed, and was a little shocked when he saw the appearance in front of him, a dam about several zhang deep had collapsed. And at this moment, there are also large and small cracks in the surrounding embankments!

Because the Taihang embankment has always been built with a high embankment, the embankment is two stories higher than the Taihang City, looking at the Taihang City under his feet, Zhao Wei sighed in his heart! I don't know if it's fate or providence, I encountered such a situation when I came to flood control.

Taihang is right now, once the levee breaks, the flood will pour into Taihang City, and this century-old ancient city will be destroyed, and many people will be displaced.

Zhao Wei turned his head and looked at the busy people and was stunned! Don’t know whether to wind a watch or bark at the moon.

The water level of the Taihe River is still rising, and the whole river surface is like a round mirror, and there is no trace of outline in sight, and soon the embankment will be broken.

"My lord! My lord! The attendant next to him waved his hand, meaning to ask Zhao Wei what to do.

"Alas!" Zhao Wei was shocked, and he didn't know what to do, although he had been flooded before, but the scene was not as urgent as today, and he really didn't know what to do at this moment.

"Hiss~~~~~" Zhao Wei clutched his beard and squinted.

"Find a few people, come and block the embankment here!" Zhao Wei had no choice but to do this first.

"No!" Zhao Tian looked at Zhao Wei with a serious face: "The river embankment has cracked more, and it is almost impossible to withstand the pressure of the river. ”

"That?! How to ......"

"Overcome rigidity with softness, divide and ......rule," Zhao Qian pointed to the embankment: "At this moment, it is better to rely on this opening to release some river water, relieve the pressure on the embankment, and then open a few more similar openings in the embankment." ”

"It's a good idea, though! But once the size of the mouth is not grasped well, the consequences are unimaginable! Maybe the entire embankment will collapse, and Taihang will burst! Zhao Wei pursed his beard and thought about it.

At this moment, the rain seems to be heavier, the raindrops are the size of peas, and the raindrops splash the muddy water on the ground, and the raindrops still feel a little painful when they hit people!

"I'm too good to die!" An old man knelt on the ground and raised his arms and shouted.

The people around him didn't seem to have fighting spirit, frowning, holding their mouths, and looking very depressed.

Zhao Wei also panicked, bowed his head and sighed.

But the miraculous thing is that although the rain is constantly falling, the water level of the river embankment not only does not rise, but also falls! Could it be the blessing of the Dragon King, or maybe the heavens heard the voices of the people.

"Ding~ Host, your plan seems to have succeeded." The system came out of nowhere.

"Hehe......" Zhao tilted his head, as if he felt a little embarrassed.

The system continued: "A big hole has been dug in the prefect's side, and the water upstream has been diverted a lot!" ”

Zhao Tian smiled slightly, turned his head to look, Zhao Wei looked puzzled, and the guards around him looked at the people who knelt down to worship the gods and froze. Now it seems that in the whole world, only Zhao Tian is the one who understands.

"Daddy!" Zhao Tian patted Zhao Wei's shoulder: "It's successful!" ”

"Oh!?" Zhao Wei turned his head to look at Zhao Tian with a puzzled expression, hoping to get an answer from her.

Zhao Tian talked eloquently: "Earlier, I asked the prefect to go upstream, which is to dig a few openings in a place where no one is around, one can discharge the flood, and the other can relieve the pressure on the Taihang embankment." ”

"I thought they would be lazy before, and I was a little worried, but this time it really is, hahaha......." Zhao Wei patted his clothes and smiled.

When the people around heard this, they praised Zhao Tian for his resourcefulness, and Zhao gave birth to a good daughter.

They all thought that everything would be fine in this way, but Zhao Wei poured a basin of cold water on them: "There is still a problem, this day is not beautiful, and the rain is unwilling to retreat, I am afraid that the diversion is just a delaying tactic, and the symptoms are not cured!" ”

Zhao Wei has been an official for so many years, and he has a wide range of knowledge, and he has also dealt with many floods, so it is not surprising to say such things.

However, now that it has been implemented, Zhao Wei has made it difficult, because he has not encountered such a situation in the previous flood control, and the terrain of Taihang is a little peculiar, and there is nothing to be done according to the previous experience, so he can only use the main canal to divert the water.

The so-called trunk canal is to build a tributary channel on top of the original water channel. Achieve the function of diverting and guiding the flow of water. However, this method does not seem to be effective for the Taihe River, because the Taihe River has a large water flow and a wide water surface, and it is difficult to implement it during the flood season.

Zhao Wei also has the attitude of a dead horse as a live horse doctor!

And at this moment, a verse came out of Zhao Tian's mouth:

"Minjiang Yao came from the sky, and his magic chiseled through the ancient heap.

Enbo is vast and even three Chu, and the Hui Ze ointment is moist and moist.

The waterfall rain in front of the axe rock, the bottom of the Fulong Pond sounded light thunder.

The embankment did not dare to quit the hard work, and the bamboo and stone management was secondary. ”

This poem was written about the Dujiangyan project back then, and drawing on this method, the traditional method of burning stones to open the mountain, after the stone is burned and broken, the gravel is pushed into the Taihe River to form a waterway, and the berm can be successfully diverted.

Yushan stretches west into the tail of this piece of the Taihe River, with artificial excavation of rock, to the waist to cut off, forming a water outlet to the east, the Taihe River is divided into two, can be divided into a part of the river water to the east, irrigating the Chengdu Plain.

The river to the east is called the "Neijiang". Among them, "Neijiang" has the meaning of artificial diversion canal, every year when the dry season is reached, the "Neijiang" is organized to dig up the "Neijiang", and the digging is lower than that of the outer river, so that the problem of river water in the dry period is solved. At the same time, the inner river is on the concave bank, and the outer river is in the convex and concave bank, which just solves the problem of sediment accumulation.

This method is wonderful, and it has solved the problem of Taihang for thousands of years for a long time, turning water from disaster to benefit, and the people who heard it were at a loss, saying that they did not understand.

But Zhao Wei was shocked, Zhao Tian actually had such a strategy, such a wonderful strategy he had never heard of, and according to his experience, this method was a good prescription, if it was his son, he would have passed on the foundation of the Zhao family to her.

Zhao Tian secretly rejoiced in her heart, not all because she didn't endorse it well before, it just happened that the teacher asked Dujiangyan about this paragraph, she didn't know, and was punished for copying it hundreds of times.

At that time, I was still secretly scolding the teacher in my heart, but now that I think about it, it is still worth it, which verifies the old saying: "If you lose your horse, you don't know if you are blessed!" ”

Zhao Wei is also worthy of the position of Shangshu, and soon arranged things properly, in order to ensure safety, he also recruited many migrant workers to build the Taihang embankment.

The other officials who want to come to the imperial court are also smart, flood control is a great achievement, and they may get a lot of silver taels, but no one has such an errand with Zhao Wei, and no one has the intention of assisting Zhao Wei, they must have investigated this matter before, and they understand that it is not easy to do, alas! I think this is also one of the reasons for the decline of big ginger.

And Zhao Tian and Zhao Wei didn't notice it at the moment, there was a pair of eyes staring at them fiercely in the people, with a fierce light, and Zhao Tian's eyes collided for a while, and then immediately lowered his head, and Zhao Tian didn't care.
