The three-month drought did not cause much damage in Qin's territory, and the greatest impact of this drought under Qin's relief measures was to make the people panic, but it did not cause too serious a drain on Qin's treasury.

But some people are worried that the river is nearly 100 miles away from Daliang City, how can it be so easy to break the pass, and how much people's power can be achieved? During the period, if there is heavy rain and wind, I am afraid that I will have more than a year, so manpower and material resources are not inferior to the Changping War, can the Qin State withstand it?

As a professional, Zheng Guo led his disciples to observe the water network and terrain near the beam, and came to the conclusion that the Qin State could definitely afford such a project.

"If you want to attack by water, it is not difficult to break the river."

Zheng Guo's voice fell, and several disciples pushed up a vertical plate sheepskin map mounted on a board cart, and Zheng Guo raised the water exploration iron ruler and pointed it on the map: "Everyone, look, the big river goes east, and the chasm goes south through the outside of Daliang City, and the distance is so close that it is like a moat of Daliang." ”

"Therefore, if you want to divert water to irrigate the city, the mouth of the water is not in the great river, but in the chasm."

"But there is one point, the chasm is not enough water, and even if Wei stores water in the chasm in order to cope with the drought, it is not enough, and it must be replenished from the upper end of the river close to the river. In the past, Wu Xinjun said that Xingkou broke the water, which is what it meant. ”

As the person who is best at hydraulic engineering today, Zheng Guo's remarks on hydraulic engineering have absolute authority, but many people still have some doubts.

"General, my king has promulgated the 'volunteer system', if the water is diverted to irrigate the city, the soldiers and civilians in Daliang City may have to become fish and shrimp in the river, I am afraid that they will lose the heart of the Wei people, not only the morality does not exist, but in order to restore the people's livelihood here in the future, the money and food that will be invested are unimaginable, so the loss of justice and benefit is probably inappropriate."

Handsome!

Wang Jian glanced at Meng Tian, who seemed to be a little too outspoken, although he didn't show it on his face, but in his heart, he couldn't help but go up a notch for Meng Tian's evaluation, and couldn't help but sigh at the Meng family's endless luck.

Different from the eyes of outsiders, the competition for the title of the first general of the Qin State between the Dongxiang Wang clan and the foreign Mengshi clan, Wang Jian didn't care about this, but Meng Tian could take into account things outside the battlefield, which made his eyes shine.

The difference between a handsome talent and a general's talent is not only in the command ability, not that you can command more than 100,000 soldiers and horses, you have a handsome talent, but you have to take into account various political factors.

For example, the post-war governance problem, the trust of the king, the pressure brought by the logistics of the army to the temple, etc., can be called a real handsome person after considering various factors.

The reason why he repeatedly expressed dissatisfaction with Wang Ben, and even the public dispute between the father and son, is nothing more than this reason.

The birds are all gone, the good bow is hidden, the cunning rabbit is dead, and the lackeys are cooked.

No matter how much he can fight, he doesn't understand the politics behind the war, and he only knows how to fight but doesn't understand how to maintain the relationship with the king, how can such a general last long after the world is settled?

"At this point, the old man is also prepared."

"Let's talk about it first, if it is not necessary, this embankment will only become an important bargaining chip in the future negotiations between the Dianke Mansion and Wei Wangzeng."

Wang Jian put his hands behind his back and looked at the west where Xianyang City was located, and his tiger eyes were full of determination, as if he had made a lot of determination.

"Secondly, even if it really reaches the point where he has to divert water to irrigate the city, the old man will withdraw part of the siege in advance, give the Wei people who are unwilling to stay a chance to leave, and finally let the old man decide the embankment to release water privately, and bear all the infamy."

"How can the general be like this!"

"Yes, even if we have to carry this infamy, we should bear it with the general!"

Meng Tian, Feng Zheng, Li Xin and others spoke one after another, but were stopped by Wang Jian waving his hand.

"If the old man wins the Wei State, no matter how bad it is, he will end up in the position of a feudal king, can you hairy boys also be able to retire in advance?"

Wang Jian glanced at a few people.

Meng Tian, Li Xin and others are still young, he knows the age of the mandate of heaven, as a military general, he does not expect Meng Fu, Wang Qi and Gong Qi to be seventy or eighty years old to be able to retreat from the battlefield of healthy physique, as long as he can make a contribution to the destruction of the country and seal the king with war, he will die without regrets.

Of course, there were some things he didn't say to the rest of the people.

Even if he retreats, will the king treat Wang Ben badly?

At least the three generations of the Dongxiang Wang clan after him, as long as they don't rebel, they will be rich and worry-free.

Moreover, with the character of the king, it is still unknown whether he will have to be swept to the end because of carrying this pot, and no one even knows whether he will really have to break the embankment.

However, his remarks are expected to reach the ears of the king in the future, and then ......

"The general said 'righteousness', then I will talk about profit."

"Just now I mentioned that the chasm is not large in water, and the generals have no doubts about this, why is the chasm connecting the big rivers not large."

Zheng Guo sighed and said: "The chasm has been built for several generations, and the water has been open for more than 100 years, and the waterway has been blocked too much, and the water should have been stopped to dig up the siltation. Unfortunately, the great wars continued, and the countries were unable to look forward to it, so there was a folk song, 'The chasm is muddy, the water in the middle of the canal, the river is surging, and the rice is difficult to fertile.' Therefore, the flood communicates with the river, but the water potential is small. ”

"And that's where the 'benefits' lie."

"If you want to attack the water, you must build a levee to store water, and when the chasm dries up, you can take the opportunity to rebuild the chasm, and the silt in it can be used as fertilizer to make the land fertile."

"It's so profitable, and it's not a meritorious act."

"The plumber is so talented, so unconfused!"

Meng Tian is not a reckless man who only understands military affairs, he can understand everything, and naturally he no longer has any worries.

After discussion, the Qin army began to recruit a large number of refugees who had previously poured into the Qin State from other countries, and began to concentrate on the chasm in the form of cash-for-work.

Zheng Guo and a group of hydraulic disciples used the girder as the north and south sections of the chasm, and the southern section of the chasm did not need to bother before the dam was built, and the northern section of the chasm was the key point of the water attack.

The most important part of the northern section of the chasm is the mouth of the ditch that leads the river.

How to open a ditch? Where? How much people's power is gained?

These three questions need Zheng Guo to lead his disciples to personally explore the field to be determined, and on the same day, under the escort of Feng Zheng and the three thousand Qin troops, he went straight to the southern suburbs of Guangwu City.

Guangwu City is located on the south bank of the Great River, which was originally a nameless mountainous land, because of Guangwu City, this mountain is called Guangwu Mountain.

Guangwu City has built two dock forts in the east and west according to the mountain situation, and in the middle is a mountain stream about 200 steps wide, which is also called Guangwu Stream in the world.

When the chasm was dug to divert the river, it was to make use of this natural mountain stream. First, the mountain stream is connected to the river bank to the north, and the river water enters the stream first and then into the ditch, so that the rock entrance of the mountain stream can control the amount of water. Otherwise, no matter how strong the embankment is, it will not be able to withstand the impact of the waves of the turbulent river, and it is really impossible to build an artificial canal that leads out the river.

Zheng Guo's ancestors were the hydraulic workers who presided over the construction of the chasm, and his family has been involved in the construction of the chasm for several generations.

For this kind of large-scale water conservancy project, Zheng Guo's family naturally retained the design map for future generations, and when Zheng Guo learned about hydraulic engineering since he was a child, the chasm was one of the examples, so Zheng Guo knew almost everything about the chasm waterway veins.

After only half a day of investigation, Zheng Guo had already figured out the key points of the chasm, and rushed back to the Bishui camp at twilight the next day.
