Daqin Engineers

The course of the Yellow River in Qin Dynasty was slightly different from that of modern ones.

From Xingyang to the north of the beam, it went north via Anyang, Handan, Shanggu (now Baoding) and then from Jingu (today Jin) into the Bohai Sea.

Therefore, the Qin army only needs to travel south along the Yellow River to attack Handan.

During the Spring and Autumn Period, Zuo Qiuming once sighed: "Tonghe is clear, life is geometric".

It means that life is too short and it is impossible to wait for the Yellow River to become clear.

Although the high sand content of the Yellow River is a bad thing, it can be said to be a good thing.

The bad things are too numerous to mention.

The flooding caused by the high sand content, the diversion and the resulting series of disasters are countless.

A good thing is that the North China Plain and the Huanghuai River Plain are actually formed by the continuous accumulation of sand and soil brought by the Yellow River and continuous diversion.

If the Yellow River is clear, Qi State does not even exist at this time, and large areas of Wei, Zhao and other countries should be covered in vast oceans.

Sitting in the carriage, Shen Bing sighed secretly under the heart of the Yellow River, which was rolling north to the east. It is no wonder that the Chinese call it the mother river.

This is not only because many countries in the Central Plains use Yellow River water for irrigation, but also because it has a huge impact on the thinking, living habits and culture of the people in the Central Plains.

Because the Yellow River will be diverted and flooded, people must take advantage of the good time to work hard, and store the harvest as much as possible to deal with possible future crises.

Thousands of years later, this sense of crisis and habit has penetrated into the blood and bones of the Chinese nation.

Make most people agree that "no one has long-term worries, there will be near-worries" and develop the habits of hard work and storage.

On the other hand, the northern nomads and western business peoples who live by water and grass generally do not have these habits and concepts.

only……

This Yellow River is not the other Yellow River.

Shen Bing didn't know when he would return to the familiar banks of the Yellow River in modern times, as well as the family members who were waiting for him to return.

When Shen Bing was sad, some soldiers rode to the carriage and reported:

"Sir, two or five hundred masters ordered you to cut logs and build bridges on the spot."

Shen Bing asked casually:

"How is the enemy situation ahead?"

It's no wonder that Shen Bing would ask this question. Qin Jun had been south for more than three days. Apart from encountering a small amount of Wei Jun in the border area, he was almost without resistance.

The soldier replied:

"Only encountering a few small groups of enemy troops, it's okay."

"But the wooden bridge was set on fire by Wei Jun!"

Shen Bing said "Oh" and got out of the car and ordered the troops to cut logs and build bridges. He brought a few guards forward to check the situation.

It was just a small river with a width of more than ten steps. It would be almost enough to build three or five rafts, so Shen Bing didn't take it seriously.

However, things were not that simple. After the pontoon bridge was built, it didn't take long before it crossed the river. Another ditch a few steps wide lay in front of him. The engineers had to stop again to build the bridge.

At this time, Shen Bing truly realized the meaning of "dense water net".

The farmland in this area is full of irrigation ditches, which are not wide but densely covered like cobwebs.

On the other hand, as there are more trees in farmland, there are fewer trees, so logging and building bridges usually involves pulling timber from miles away.

If it weren't for the help of Mengliang and the hundreds of soldiers under his control, it would not be easy.Have

But even so, this still won't affect the marching speed of the army.

The marching sequence of the Qin Army during combat is usually like this:

At the front is the spy.

The spies generally scurry around in units of five or more.

Their purpose is to find out where the enemy is and where there are obstacles.

A team of cavalry was followed.

This cavalry has about 500 troops, which can be said to be Qin Shi's rapid reaction force.

As long as the spies detect the enemy and send out a signal, they will rush for reinforcements.

If the enemy is a small harassment unit, the cavalry will solve it.

If the enemy is a large army or a small and large walled city, wait for reinforcements from the rear infantry.

Behind the cavalry are engineers and a thousand-man team.

Needless to say, it was the troops of Shen Bai and Zhang Xuan.

They were lightly loaded and moved faster, meeting the river and building a bridge ahead.

Finally, the main force of the Qin army.

The main force is slow because of its large number of troops and a large number of supplies.

Shen Bing and others used this speed difference to build bridges.

However, after another two days, Wei Jun still didn't meet him. At the same time, several pontoon bridges were repaired in the rear, and Shen Bing felt a little hairy.

After thinking about it, Shen Bing stopped Meng Liang who was walking outside the carriage:

"Zuofu, is your map still there?"

Meng Liang was stunned and asked:

"Map, what map?"

Then he slapped his head and thought:

"Here, the map... the map of Wei State!"

"My husband, forgive me, my subordinates forgot where to put it."

"Look for subordinate Rong!"

Speaking of getting into the carriage and tumbling around in it, it took a long time before he came out with a bag of dried meat, and said excitedly:

"Let your subordinates find it!"

Shen Bing saw that the sheepskin map was used by this guy to wrap dried meat.

This is so...

Shen Bing didn't know what to say.

Not long ago, he said that he would work hard and work hard to cure it, right?

He took the map and asked Shen Bing how to fight Wei Guo?

It turned out that Wei Guo actually...

Wrap dried meat with such a precious map?

Na Mengliang hadn't noticed that Shen Bing's expression was different, and spread the map and handed the jerky to Shen Bing:

"Sir, how about a few dollars?"

"Although it's not as delicious as that scallion pancake, but it can also solve the hunger for a while!"

Shen Bing:...

But at this time, Shen Bing didn't have time to care about with Meng Liang, he grabbed the dried meat into Meng Liang's arms, spread the crumpled map on the carriage and flattened it.

The map is still not detailed enough, there are many ditches and rivers that are not marked.

But this does not seem strange.

Because many rivers and canals may have been opened after the map was made, some of them may have been dug by the people themselves, and even the map of Wei State is not available.

Looking at the map, Shen Bing wrinkled his head, the battle seemed not as simple as previously thought.

Thinking of Shen Bing, he confessed to Meng Liang:

"Look at the troops here, I'll go to the general to discuss something!"

Meng Liang answered, but when Shen Bing boarded the carriage, he asked from behind:

"Sir, do you really not bring some jerky?"

Shen Bing suddenly felt inhumane...

The carriage went all the way back to find Yang Duanhe who was looking at the map, and immediately stepped forward to report.

"General, his subordinates think that this battle is deceitful."

Yang Duanhe raised his head:

"Oh, let's hear it!"

Shen Bing pointed to the map and said:

"Look at the general, I'm going against the current when going south along the Yellow River."

"And Wei Jun went downstream along the Yellow River."

"This way, the Wei army avoids fighting, I'm afraid it is to lure the enemy into deep and lead our army to the city of Daliang."

"Then send naval forces down the current to attack the rear of our army."

Yang Duanhe smiled and said:

"What the husband said is reasonable."

"But Wei Guo does not have the talents of a husband, they don't know how to use troops."

"Sister, don't worry!"
