I am a nobleman in Spring and Autumn

Chapter 370
It is inevitable that the theoretical school will have many hypotheses, that is, there is no actual data, and hypotheses are put forward based on what may happen.

Of course, Sun Tzu is not a purely theoretical school, but tends to be more strategic, lacking data research from field visits.

Standing too high to see below the foot of the mountain, similar situations don't happen to just one person.Strategic mistakes caused by this have happened repeatedly in history.

Zhiyao decided to take "Puyang" as the level of "capital".

In the current "Puyang" city, the city wall is about four miles long and three miles wide; the highest wall is nine meters, the lowest seven meters, and the thickness is generally more than four meters; the city wall is not completely straight, there are still some bends, and the overall appearance is still a straight line; Even if the big river is on the side, there is still no such thing as a moat in the city.

According to historical records, Duke Cheng of Wei moved his capital to "Puyang" in 629 BC, and since then "Puyang" has become the political, economic, and cultural center of Weiguo.

Of course, according to Zhiyao’s contemporary historical records, the relocation of Wei State was from “Chaoge” to “Diqiu”. Near "Puyang", "Puyang" is used more frequently than "Diqiu".

"Has there been any war in 'Puyang' in history?" Zhiyao thought.

There must have been many battles that took place in "Puyang", and three of them are especially remembered, namely the battle between the Yellow Emperor and Chi You in ancient times, the battle between Xiang Liang and Zhang Han at the end of the Qin Dynasty, and the fight between Cao Cao and Lu Bu at the end of the Eastern Han Dynasty. .

In those wars, there was no record of "Puyang" being attacked by water.

Zhiyao can remember Xiang Liang and Zhang Han, Cao Cao and Lu Bu.As for the battle between the Yellow Emperor and Chi You, which belongs to ancient times, it is more regarded as a mythical story.

The number of great battles that took place in "Puyang" is too small, which can also prove to a certain extent that "Puyang" is not an important place for military strategists.

There are many important places for military strategists, and they will definitely break out great wars again and again in the long history.

The reason is that the local area has too much strategic value, and if it belongs to a place that must be contested, it will definitely fight vigorously, and repeated wars will inevitably occur.

Zhiyao and Sun Wu walked around and discussed a lot, including which places must have cities as a barrier for the capital, and the construction of cities can also be used as a stronghold to build local agriculture.

"If 'Puyang' is the capital, connecting the two sides of the strait is the top priority." Sun Wu said.

Now there is only one bridge across the two sides of the river, which is on the "Mengjin" side of the Zhou royal family's territory.

Zhiyao watched the torrential river sweeping towards the east. Standing on the south bank and looking to the north bank, it was already a blur. The width of the river was at least 800 meters, and she was really worried.

Dahe, the most exaggerated width can reach [-] kilometers, it is located in Dacheji, Changtan County, Henan; the narrowest is only more than ten meters, located in Yehu Gorge.

In the next few days, Zhiyao personally inspected the south bank of the Dahe River near "Puyang". After a careful survey, the narrowest width was more than 400 meters, especially far away from "Puyang", which is not suitable for building bridges. location.

In order to solve the bridge problem, Zhiyao had to summon Gongshuban and Dou Shuo.

"Yao wants to build a bridge across the big river." Zhiyao said straight to the point.

Gongshuban and Dou Shuo looked at each other, neither of them spoke, quietly waiting for Zhiyao's next post.

Zhiyao went on to say: "Needou's family is located near 'Puyang' to explore the riverbed, find a slightly higher riverbed, fill it with large ships and load rocks to make islands, and tilt the sediment to form islands. How can the river not be obstructed, so that In the rainy season, the river floods both sides, and there are many people who rely on the Dou family."

The Zhi family is the only Dou family who majors in water conservancy engineering. Who else can Zhi Yao rely on if he doesn't rely on them?
Dou Shuo was completely immersed in Zhiyao's plan to use big boats to carry big rocks to fill the river. The more he thought about it, the more he felt that this was a historically pioneering method, and it was absolutely feasible.

Of course, every water conservancy project has the characteristics of pulling the whole body. The sudden increase of a certain riverbed cannot have no effect on the height of the riverbed. It is indeed necessary to consider and design rationally and rigorously.

Dou Shuo said confidently, "Exploring the riverbed is easy. I just don't know where and what kind of bridge the eldest son wants to build?"

What bridge to build?It can be like the "Mengjin" side, with huge stones and timber structures, that is, the wider the river, the more difficult it will be to build.

Zhiyao said: "The river is filled with boulders to make an island, and mud is accumulated on the island to form an island. Don't use it too wide. It can be more than [-] meters long and wide. The distance between each island needs to be determined by the strength of the Dou family and the Gongshu family. .At that time, it will be built with stones, erected with trees, or supported by iron cables. Is it possible?"

This set of methods can be regarded as a fool's operation.The main reason is that it is not like modern times. There are many technical supports when building bridges in the river section, and bridge piers in the river can be built.

It is precisely because of the need to build artificial islands that Zhiyao's previous request was made, that is, the appearance of artificial islands should not lead to the possibility of flooding on both sides of the Strait, or else it would be a man-made natural disaster.

Dou Shuo said with a thoughtful expression: "Maybe we can build a dam in 'Cao' first in summer, so that the river can be filled with water in the north section, and the water level in the south section will drop, making it easier to fill rocks?"

Now the Dahe has two outlets to the sea, and it is roughly divided into two in modern Huaxian County.This is a new situation after the diversion of the Yellow River. At one time, Wei and Qi were plagued by floods. The impact lasted for more than 200 years, and it slowly recovered at the end of the Warring States period where the river flooded.

Zhiyao just put forward an idea, whether it works or not requires technical personnel to discuss it, and it is necessary to construct a relevant model based on the actual situation, and to draw a roughly reliable conclusion through repeated trials.

Model?In fact, it is like something more refined than a sand table, but it is more particular than a sand table for military use.

In addition, the sand table was not originally created by military strategists, but was actually created by a family engaged in water conservancy projects.Later, it was used more times in wars, and many people mistakenly thought that it was the first sand table created by military strategists.

Zhiyao needs to wait for Dou and Gongshu to discuss a feasible plan, including which section of the river, how much labor is expected to be needed, and how long it will take.

"I also made up for 'Zhiyao' being the first operation to build a large ship in the Central Plains!" Zhiyao felt something strange in her heart.

What?Zhiyao turned out to be the first person to build a big ship in the Central Plains?This is indeed it!

In the original history, Zhiyao used the envoys of the State of Wu to go on a mission to the State of Jin, and built a large ship that could accommodate more than 2000 people.

The envoy of Wu State saw through Zhiyao's strategy and was unwilling to take the big ship of Jin State, so Zhiyao Guang had a plan but was unable to use it, and Wei Guo escaped.

How big should a ship that can carry more than 2000 people be?The historical data only mentioned a big ship, and did not record the relevant data of the big ship.

Of course Zhi Clan currently has a shipbuilding factory, one is located in "Xiyang" in the southeast of "Ye" city, and the other is near "Shuzhou" near Yan State.

So far, Zhishi has built the largest boat, which is 24 meters long and 16 meters wide. What is consistent is that they all have a keel.

There are two different styles of boats, the design concept of which is from Zhiyao. Among them, Louchuan is a flat-bottomed boat, and Fuchuan is a sharp-bottomed boat.

The factory for building building boats is located in "Xiyang", and the place where Fuchuan is built is in "Shuzhou".

By the way, "Shuzhou" is a brand-new administrative unit. There are not many Lishu there. The geographical location is near the mouth of the Dabei River. It is precisely because of this that the construction of Fuchuan is arranged there. .

In the current time period, Zhiyao pays more attention to building boats.

After all, going to the sea is not the main thing, the demand for ships in the inland river section is more important, how can you do things regardless of the importance?

Three months later, Gongshuban and Dou Shuo come together to ask Zhiyao to see him, and it seems that the task given has come to a conclusion.

"How is it?" Zhiyao waited for three months without urging her even once. In fact, she had been waiting impatiently for a long time.

Gongshu Pan and Dou Shuo looked at each other, and the former said, "Filling rocks to build an island, Gongshu and Dou think it is feasible."

After hearing the answer, Zhiyao was greatly relieved.

Dou Shuo lowered his head and said, "If you build a dam to stop the water, you need to pay attention to the year. In addition, if you fill in rocks to build an island, you may need to build dams on both sides of the bank to prevent accidents."

Zhiyao, who had been mentally prepared for a long time, breathed a sigh of relief, and frowned again.

Build dams on both sides of the river?It is conceivable how large the amount of engineering will be and how much labor will be used.

Dou Shuo paused for a moment, and then continued, "Suo thought, maybe we can build one or two islands first, then check the water level for confirmation?"

The width of the river exceeds 600 meters. In fact, the impact of building an island with a diameter of 20 meters will not be too great.The difficulty lies in the extent to which the artificial construction of islands will change the riverbed. If the underlying base covers a small area, the impact will naturally be minimal.

Zhiyao didn't dare to make fun of Dahe. Once there was a problem with Dahe, it would definitely be a big trouble for a long time.

"It's okay if we continue to explore further away from 'Puyang'." Zhiyao made a compromise.

The bridge must be built, and the plan with the least difficulty and the least troubles will definitely be the first priority.

Gongshuban and Dou Shuo, who received the signal, became less psychologically stressed, and left after talking about what should be discussed.

Zhiyao thought about it for a long time, but she couldn't think of the memory of who built the bridge in Dahe, Hebei in history.

Zhiyao is wrong here. Historically, in the late Spring and Autumn Period, a river-crossing bridge was built at a place called Jijin. Although the bridge was damaged later, it was repaired and used again and again. It was used in the Sui and Tang Dynasties, and the name changed from "Jijin" Jin" was renamed "Suxukou" in the Warring States Period, and was renamed "Baimajin" in the Western Han Dynasty. Later, the name "Jijin" was used for several years in the Western Jin Dynasty, and it became "Baimajin" in the Eastern Jin Dynasty, and the name was changed repeatedly. .

This time Zhiyao was worried for less than a month, and after the conditions were relaxed, Gongshu and Dou really got good news.

It's not a coincidence, it's just the geographical location and the environment. After the two families explored the place that has no name yet, that is, the Jijin River section, they brought good news to Zhiyao!
