The entire Tianjin City is just a small city with a long east-west and short north-south, shaped like an abacus. It is called "abacus City" by many people. It is only a circumference of more than nine miles. There are many crafting batteries around this Tianjin City, and seven crafting batteries were set up respectively, but the streets were only east, west, south and north.

If such a "exquisite" small city is to be equipped with more than 200 kilometers of underground drainage channels, it is obvious that most of the drainage channels are actually some "bad land". No matter how you calculate this, it is just two words, "waste".

At present, the Celestial Empire is in a mess and there are many places that need money. Even if you don’t have to consider the money issue, you just want to pull down the thousands of soldiers and civilians from the busy river management project to tinker with these "hidden military caves". Wei Zheng couldn’t figure it out, and Qin Rigang couldn’t figure it out.

And in Beijing, many people also can't figure it out.

It is said that when senior officials in Beijing saw the additional "fate money plan" submitted by the Ministry of Finance, many people couldn't figure it out and immediately became very angry.

It is said that Zeng Guofan, who was already the deputy director of the National Education Commission at that time, even linked Tianjin's huge underground drainage system with the "Zheng Guoqu Project" two thousand years ago.

The so-called "Zheng Guoqu Plan" that Zeng Guofan thought of refers to an event that occurred between the Han and Qin countries in the late Warring States Period.

Among the seven kingdoms of Qin, Qi, Chu, Yan, Zhao, Wei and Han at that time, Qin, whose national strength was booming, had already shown its tyranny. Facing the powerful Qin who was eyeing and wanted to unify the country, Han, which was unfortunately the first to bear the brunt of the country due to geographical reasons, was already weak to a point that was vulnerable. The bad luck of being swallowed by Qin seemed to be just a matter of time.

For the purpose of dying struggle, in 246 BC, King Han Huan of Han actually came up with a very great and very clumsy so-called "exhausted Qin" strategy in 246 BC.

King Huan of Han used Zheng State, a master of his country's famous water conservancy engineering technology, as a spy, to send him into Qin State, and lobbying the Qin State to drill a large irrigation channel between the Jing River and the Luo River (Bei Luo River, Wei River tributary). Although this plan, on the surface, was very beneficial to the great development of Qin's agriculture, its real purpose was to use this to consume the strength of Qin State.

Of course, Zheng State's attractive plan is undoubtedly a timely help for Qin State, which is troubled by how to better develop water conservancy and bring its own agricultural production to a higher level.

Therefore, King Zheng of Qin not only happily adopted Zheng State's suggestions, but also immediately solicited a large amount of manpower and material resources and handed over the construction of this huge water conservancy project by Zheng State.

However, during the subsequent construction process, because King Huan of Han's conspiracy of "exhausted Qin" was exposed, King Qin was furious and ordered the killing of the evil Zheng State.

At the critical moment of life and death, Zheng State made a statement that "the first minister was a branch, but it was a natural benefit for Qin. The minister was the fate of Han Yan for several years and the achievements of Qin for the construction of the ages" not only eventually led to the requisite revocation of the King of Qin, but also continued to be reused as always.

More than a decade later, the omni-channel of this huge water conservancy project using Jingshui as the water source and irrigating farmland north of the Wei River was completed, known as the Zhengguo Canal.

The completion of the Zhengguo Canal benefited tens of thousands of hectares of farmland, and the already powerful Qin State achieved double harvests both economically and politically.

"Records of the Grand Historian" and "Book of Han" say: "The canals were filled with water, and irrigated more than 40,000 hectares of turmeric land, and collected them one bell of acres. Therefore, Guanzhong was fertile and there was no bad year. Qin was rich and powerful, and eventually joined the princes..."

At that time, one bell was six stones and four dou. This yield was obviously many times higher than that of a mu of only one and a half stones in the middle reaches of the Yellow River.

Of course, the reason why Zeng Guofan thought of "Zheng Guoqu" at this time was definitely not because of the benefits of Zheng Guoqu, but because of Zheng Guoqu's conspiracy.

Although the general situation of the Celestial Empire is now settled, there are still a small group of old and foreign forces who are resentful to the Celestial Empire regime. They take advantage of the enlightened political atmosphere of the Celestial Empire to fan the cold wind and light ghost fires everywhere, and dream of taking back everything they have lost.

Therefore, Zeng Guofan believes that around Tianjin's underground drainage system, it is impossible to assert that there are no vicious people with ulterior motives like King Han Huan and Zheng State.

The truth is obvious. Compared with the big goal of eradicating the entire Haihe River Basin, what is a small Tianjin worth? Why do you have to smash a lot of money, manpower and material resources into the invisible underground in Tianjin at such a critical moment?

What's more important is that if the method of spending money like Tianjin is imitated by everyone, the consequences will undoubtedly be even more serious.

Zeng Guofan was not the only one who had this state of worry. In addition, the anti-rebel movement in the Celestial Dynasty was still in its prime, and this seemingly originating skepticism was immediately accepted by more people as soon as it appeared.

The Du Academy of Sciences has a Counter-Revolutionary

This conclusion made Lin Haifeng and Zheng Nan laugh and cry.

Lin Haifeng was unaware of the overall design plan for the entire Tianjin underground drainage project at the Capital Academy of Sciences. However, Zheng Nan was the initiator of the plan.

Before the Capital Academy of Sciences began to design, Zheng Nan, as Premier of the State, clearly reminded the technicians involved in the design of Tianjin's underground drainage engineering to learn from the lessons of Beijing (because Beijing's old city has long had its own fixed pattern, the Beijing Municipal Government not only encountered many unimaginable difficulties in the transformation of the old city's water supply and drainage system, but also had to waste a lot of financial, manpower and material resources). Tianjin's underground drainage main system must either not be carried out, or if it is done, it must be in place in one step, and it must be able to meet the expansion and development needs of Tianjin for more than 100 years in the next year.

Therefore, the engineering and technical personnel of the Capital Academy of Sciences designed the complete underground drainage system in Tianjin in accordance with the future prospects of Tianjin. The drainage main lines are centered on the existing Tianjin city and extend to various large residential and industrial areas in the future...

It is this vision and excellence that has enabled Tianjin to set a brilliant model for all future urban construction of the Celestial Empire. In the Celestial Empire, there has never been a "zipper link" in the following century, and there has never been a duplicate construction project similar to that which is dug out today, covered tomorrow, and dug out the day after tomorrow.

But that is all a story after all. Now, if we really follow the reasoning of Zeng Guofan and others, Zheng Nan would undoubtedly be the "King Han Huan".

As a result, an underground drainage system project in Tianjin was eventually disturbed by the National People's Congress.
