In the history of the previous life that Yang Yi is familiar with, Dujiangyan is a large-scale water conservancy project organized and built on the basis of the excavation of the turtle spirit of the predecessors during the Warring States Period, Dujiangyan is a large-scale water conservancy project that took 20 years to organize and build on the basis of the turtle spirit of the predecessors, as one of the historical and cultural cultures of Chinese civilization, until 2,000 years later, it still plays the role of flood control and irrigation, making the Chengdu Plain a "country of abundance" with water and drought from people and fertile fields.

Water can bring disasters to human beings, but the continuation of human beings must be closely linked with water, the greatness of Dujiangyan is not only flood control and diversion, but more importantly, it can reasonably introduce the water of the Minjiang River into the Chengdu Plain.

Yang Yi wants to establish a real "country of abundance" in Daguang, and water conservancy is definitely a hurdle that cannot be bypassed, if he can obey the water control of Hengchuan, it will be a big step forward for Shudi, so he will feel inexplicably excited when he learns that there is such a person as Wen Jihuai.

Yang Yi tried to recall, while explaining in detail, the construction principle of Dujiangyan is actually not complicated, theoretically it can even be said to be very simple, as long as people with a certain amount of common sense can understand it thoroughly, its essence only lies in the word "exquisite".

As a water conservancy expert, Wen Jihuai has already listened dumbfounded, the ancients were not as dull as they imagined, but many things do not have professional terms, such as fish mouth and flying sand weir use the impact of water to form a whirlpool, and then throw out the sand and gravel, so as to prevent the principle of sand and gravel precipitation, Yang Yi just simply described, Wen Jihuai has suddenly understood, and even can tell some personal details and suggestions.

There are not many things that can be described by the word infinite vastness in the world, and apart from the universe, the most recognized by human beings is the human mind. The infinite continuation of thinking has created a developed scientific and technological civilization of mankind, and it will continue to continue, the only obstacle is the bottleneck.

Sometimes a small grain of sand can cut off a vast river, and you need to find something that fits in the vast river, which may be difficult to find, and even takes thousands of years ago. But once this grain of sand is opened, the turbulent torrent will be unstoppably pushed forward, just like human beings have stood still for thousands of years, but a small steam engine has brought the industrial revolution to mankind, and then opened the door to a new world, which no one expected.

Yang Yi, who was squatting in the mud, was not engaged in extracurricular activities, let alone showing off his talents, what he did was to help Wen Jihuai open the bottleneck in his thinking about water control, and let him take the lead in his "Land of Abundance" plan.

Wen Jihuai went from doubting at the beginning, to being shocked by Yang Yicaixue, and finally falling into deep contemplation, the excitement and sadness in his heart are only known to him, it is like suddenly a fairy-like girl appears in front of a pervert, but the pervert is out of reach.

Maybe Wen Jihuai was full of anger at the beginning of Jianghe, because it ruthlessly destroyed his family, but after so many years, he has been with Jianghe day and night, and even dreams can dream that the vast river has become docile and pitiful under his own guidance, so unconsciously, Wen Jihuai has fallen in love with this surging river, maybe this is the real love born from hate.

Yang Yi's rudimentary shape made Wen Jihuai seem to see a more beautiful and flawless girl, but...

"But Your Highness... If we want to build such a diversion weir, we still can't avoid the mountains opposite. Wen Jihuai's words were full of loss, even if this fool's plan to move mountains was proposed by himself, he questioned from the bottom of his heart whether such a move was really feasible.

What kind of concept is decades, Wen Jihuai even doubts whether he can live to that time.

Yang Yi stood up, rubbed his somewhat sore neck, looked at Wen Jihuai, who was a little lost, and said, "Give me some time, if I can find something to help, maybe I can shorten the time for building the weir to ten years, or even five years." ”

Wen Jihuai smiled bitterly and shook his head and said: "Your Highness, don't be funny, even if you let all the people in Shu come to excavate, it will not be possible to build it well in five years." ”

"Hey... Do you think I'm joking? Yang Yi looked at the mountain peaks on the opposite bank and smiled.

Wen Jihuai was stunned, looked up at Yang Yi, and said with a little surprise: "Then Your Highness, what are you looking for to help?" Could it be a fairy artifact? ”

"Hmm... For this world, that thing may really only be deserved by immortals. ”

"What?"

"Dynamite..."

When Yang Yi returned to Chengzhou Mansion, it was already nightfall, Tao Yong's Thorn Mansion was burned to ashes by him, Yang Yi wanted to settle in and had to wait for the new Thorn Mansion to be built, and after being homeless, he could only temporarily live in Su Mansion.

Su Mansion has been surrounded by heavy troops since the beginning of this year, first Tao Yong's people, and then Yang Yi's people, but the nature of the two is completely different.

Now that the Chengzhou Mansion is determined, Tao Yong's remnants and even Gao Zuozhen's remnants may come out to make trouble at any time, even if Yang Yi does not consider his own safety, he must also take into account the safety of the Su Mansion, so the five hundred heavy troops will be unable to surround the Su Mansion.

When Yang Yi entered Chengzhou City, it was already completely dark, so no one knew that he had returned.

Coming to the gate of the Su Mansion, Yang Yi handed over the mount to the next person to lead the stable, and he couldn't wait to go to the house.

But when Yang Yi first arrived at the door, he suddenly found that the figures in the Su Mansion compound were shaking, and there were actually one hundred and ten people in the courtyard, and some of them even carried blades.

Yang Yi's heart was cold, who dared to bring so many people to Su Mansion to make trouble so boldly? waved his hand at the moment, signaling Monkey Jian'er and the others to prepare for battle.

As soon as he walked into the compound, Su Fan, who heard the news, greeted him: "Yi'er! You're back, worried about your uncle's death! ”

Yang Yi saw Su Fan's somewhat excited smile, and hurriedly replied, "Uncle is well." ”

Su Fan took two steps forward and hugged Yang Yi's shoulders, looked Yang Yi up and down with mud stains, but there were no scars, and then he breathed a sigh of relief and said: "It's good to come back, it's good to come back!" ”

Yang Yi tilted his head, looked at the swaying figure in the courtyard and said, "Uncle, what is the situation with those people?" ”

Yang Yi's face was gloomy, as long as Su Fan said that these people were uninvited guests, Yang Yi would immediately order these people to be destroyed, some time ago for his own affairs, Su Mansion was worried about the days of a few months, and now if anyone dares to disturb the peace of Su Mansion, Yang Yi will not spare it. 7110
