Even if he did not have a high degree of education in later generations and did not know much about history, it was difficult for Liu Ying to forget the prehistoric water conservancy project like 'Zheng Guoqu', which enjoyed a prestigious reputation in the history of the Qing Dynasty!

Speaking of which, the construction of the Zhengguo Canal by the Qin State back then also had some black humor.

Exactly fifty years ago, that is, in the first year of the reign of King Qin, Qin Guodong sent a letter to the valley, and the intention to unify the Kanto region became stronger and stronger.

For South Korea, which was blocked outside the Hangu Pass and faced the old Qin Ruishi head-on, the increasingly strong eastward trend of the Qin State naturally meant unprecedented danger.

At that time, Gongzi Fei, who had just returned from his studies under the Jixia, proposed to carry out reforms within Korea to strengthen himself in response to Qin's increasingly strong offensive intentions.

But it's a pity that the proposal of the son Han Fei was not accepted by Han Wangran at that time, but was a little-known waterman who became Han Wangran's 'strategist' to thwart the ambitions of the wolf son of Qin.

This hydraulic worker, who was cited by Han Wangran as a 'national soldier', is Zheng Guo, a Korean.

According to Zheng Guo's strategy, if Korea wants to stop Qin's eastward departure, it must attract Qin's attention from Kanto back to Guannai, that is, the land of Sanqin.

As a result, a ridiculous scheme called 'dragging you to develop' was adopted by Han Wangran and used on the Qin State, where Yingzheng was the king and Lü Buwei was the prime minister.

Regarding South Korea's scheme, the young monarch Yingzheng, who was only 12 years old at the time, may not have seen it, but he also failed to escape Lü Buwei's old and spicy political vision.

Is Zheng Guoqu good?

Good!

It's so good that you can't fault it at all!

Once the Zhengguo Canal was opened to water and the acres of fields along the coast could be irrigated, no one could stop Qin's efforts to unify the world.

But it is good that it can be used by South Korea for the purpose of 'tired Qin, lack of Qin, and hurt Qin', and the consumption of materials required by Zheng Guoqu is also daunting.

But even so, Zheng Guoqu still repaired it!

From the first year of the reign of King Qin to the ninth year of the reign of King Qin, almost all of the attention of the Qin State, as well as more than ninety percent of the manpower, material resources, and financial resources, were concentrated on the Zheng Guoqu, which carried the fortunes of the Qin State.

In the palace, King Yingzheng of Qin only eats eight points full, and the skirts of the harem concubines do not mop the floor!

Xianyang, the capital of Qin, almost no longer see the Kwantung merchants who come and go, and when they look up, they are all Qin people with hoes on their backs and short beatings!

It was under this unity that the Zhengguo Canal was finally completed, irrigating more than 40,000 hectares of barren land along the coast.

In the autumn of the second year of the opening of the Zhengguo Canal, the average yield of millet along the Zhengguo Canal reached an astonishing six stones and four taels!

Then, it was Qin Ruishi who was majestic and high-spirited, almost swept away the six countries of Kwantung in one fell swoop with a flat push posture, and Qin Fen VI's aftermath was finally able to dominate the world.

I have to say that even in today's Han Dynasty, the water conservancy project at the level of Zheng Guoqu is still a huge pit with a success rate infinitely close to zero.

Nowadays, the Qin-Zhengguo Canal, which has been built for nearly 40 years, has also lost most of its effectiveness under the erosion of time, war, and chaos in the world for more than ten years······

"In the tenth year of the reign of King Qin, Zheng Guo Qucheng, the land along the coast is acres of lugen, but it is a good land at the age of one!"

"However, since the death of King Qin, the second emperor has been established until now, Zheng Guoqu, there is no craftsman who is proficient in hydraulic engineering."

Speaking of Zheng Guoqu's current situation in a slightly heavy tone, Yang Chengyan's face couldn't help but sink a little more.

"First of all, His Majesty seized Qin Xianyang, Xiang Yu divided the princes of the Eighteen Roads, and the land of the Three Qins was actually owned by Zhang Han, Sima Xin and others."

"When Your Majesty returns to the Three Qins, the Kanto region will be in turmoil, first destroying Chu, and then destroying the princes with different surnames; So far, Zheng Guoqu has been in disrepair for more than ten years······"

Hearing Yang Chengyan's words, Xiao He couldn't help but sigh and nodded.

"Since the first year of the Han Dynasty, His Majesty planned to take Chang'an as the capital, and so far, Chang'an City has not been built."

"And Zheng Guoqu, although the ministers have the heart to repair, how can the treasury be empty, and the cost of longitudinal support for the army to go out is also stretched······"

"Therefore, a few years old, Zheng Guoqu was an official of the local county and county, and he widened it a little with the courage of the township."

"However, the width of the canal is the number of direct waters; The wider the Zhengguo Canal is in the local counties, the slower and thinner the water of the Zhengguo Canal will be······"

Hearing this, Liu Yingzong was confident, and her face couldn't help but become a little solemn.

"With the strength of the Qin country, it took ten years to build the Zhengguo Canal, and in just a dozen years, it almost lost its effect······"

Thinking with a little surprise, Liu Ying calmed down a little and looked at Xiao He solemnly.

"That's it, according to Xiao Xiang, what should be done about this renovation of water conservancy?"

At this time, Liu Ying has also fully understood: the 'Guanzhong Water Conservancy' in the mouth of his father Liu Bang is actually Zheng Guoqu.

It is only necessary to get the Zhengguo Canal done, and it is not even necessary to restore it to the extent that the land along the coast can yield more than six stones per mu, even if it is next year, the grain output in Weibei will not continue to decline compared with this year, it is enough.

On the contrary, if Zheng Guoqu didn't get it done, then no matter how many knee-length canals Liu Ying repaired and how many waist-length streams he dredged, it would be useless.

In this way, Liu Ying's tasks that need to be completed before her father Liu Bang comes back are very clear.

- Zheng Guoqu!

Even if Zheng Guoqu's condition cannot be improved, he must find a way to prevent Zheng Guoqu's condition from continuing to deteriorate.

"Alas, alas, time is tight."

"If you have two to three years, you can get the cement out first."

"No matter what, it's better than now, it's all a channel that is compacted with soil?"

Secretly slandering to herself, quietly remembering the matter of 'cement' in her heart, when Liu Ying raised her head again, her temperament was completely absent from the immaturity of a thirteen-year-old boy.

"Please also speak up to Xiao Xiang."

"What is the obstacle to the renovation of Zheng Guoqu?"

Seeing Liu Ying so solemn, Xiao He couldn't help but sit up straighter, and after only a little thought, he gave his own answer.

"Money!"

"The treasury is empty, and the treasury and the treasury have no money and food!"

"If you have no money, you will not be able to provide for the needs of the watermen; If there is no food, there is no way to recruit and transfer soldiers and people to repair. ”

"Moreover, this time Your Majesty went out on the expedition, and there were three households in Guanzhong, one of which had a man as a pawn, and another family who lost a strong man."

"Regardless of the lack of money and food, there is no one in the pass today, and the renovation of Zheng Guoqu may not be able to talk about it······"

Listening to Xiao He's sigh and sigh to express the bitter water, Liu Ying's face froze slightly, and she subconsciously turned around and looked at her mother Lu Pheasant, who was sitting behind her.

When Lu Pheasant nodded kindly, Liu Yingcai turned around and looked at Xiao He's gaze, revealing some doubts.

"No money?"

With a contrived face, Liu Ying turned the forehead with the words 'I don't believe' to Yang Chengyan on Xiao He's side.

"If you are at a loss, today's Shaofu, when there are still tens of thousands of dollars?"

"How can Shaofu say that the treasury is empty, and what does Xiao Xiang talk about 'no money inside'?"
