Daqin Engineering Corps

Shen Bing's argument convinced Chun Yuyue not only from the battle in front of him, but from the overall situation of governing the country and even the entire Central Plains.

This is not the vision that ordinary people can have!

After signaling Yang Duanhe to reprimand Shen Bing, Ying Zheng sighed:

"I didn't expect such a small coward to have such talents. It's really rare!"

"Can you hear me clearly?"

"In the future, whenever we fight, we must distinguish between hurting the country or destroying the country."

Yang Duanhe and Chunyu Yue hurriedly responded.

Then Yingzheng glanced at Chunyuyue again, secretly thinking that the prince's teachings should not be ignored, and it was related to the future of the Great Qin Dynasty.

But Chun Yuyue, a great Confucian, advocated benevolent government, but he was too pedantic.

It will not be a good thing if the prince gets into this habit in the future.

If not...

Thinking of Ying Zheng, he shook his head again. It's still early, and we will discuss it in the future.

Of course, Shen Bing on the other side didn't know what was said in the tent afterwards, he was just glad that he escaped from Chun Yuyue's "claw".

When he returned to the camp, he found that the pontoon bridge had been built, so he ordered the troops to move on.

Meng Liang chased up from behind in his carriage and asked:

"Coward, what did you talk about here?"

"Did the general tell you when I can return to Handan?"

Shen Bing rolled Meng Liang's eyes, and replied:

"Nothing was discussed, but trivial matters."

I wondered in my heart whether this guy really didn't know or pretended not to know?

Thinking about going back just after you came out?

This time, if Wei Guo is not destroyed, he will not be able to go back.Just spend the winter here you...

Thinking back, Shen Bing found out that he really didn't talk about anything when he went here.

If there is any gain, it is to know the difficulty of water attack.

However, this will have to wait for field inspections to be sure.

As for the attack on the supply line that he was worried about, Yang Duanhe didn't seem to take it to heart.

Is the situation really as Yang Duanhe said?

For some reason, Shen Bing always felt uneasy.

133章 困难

The situation afterwards was indeed as Yang Duanhe said, there were no Wei soldiers blocking the way, and abandoned cities and villages were everywhere.

In fact, let alone the road, when Qin Jun arrived at Daliang City on the ninth day, he found that even the small fort outside the city was unguarded.

These small forts are strongholds built by the Wei army outside the city to echo Daliang City.Most of them are built on high places for condescending defense, and they are also close to the river, so they can easily be supported by Wei Shuijun and infantry.

Wei Jun even handed over these dangerous small forts to others, which made Qin Jun who took over it feel unbelievable.

But of course the Qin army would not be polite, and divided into several parts and spread out in several directions to seize the commanding heights and important places outside the city and surrounded Daliang City.

Among them is a place called Guangwu Mountain in the north of Daliang.

This Guangwu mountain is divided into two small hills on the left and right, and a mountain stream with a width of more than [-] steps in the middle is called Guangwu stream.

The water of the Yellow River opens an estuary from here and flows into the Bian River surrounding Daliang City through the natural Guangwu Jian.

Like other places, this Guangwu Mountain also has a small fort:

On the east and west hills, there is a small fort that can accommodate more than [-] people, and there are several trebuchets in the fort.

This is a dangerous place where one man guards the gate and ten thousand men cannot open it. The small forts on the hills can use bows, crossbows and catapults to reinforce each other:

If the Qin army attacked the East Fort, the Wei soldiers in the West Fort could use bows and crossbows and catapults to attack the rear.

On the contrary, the Qin army attacked Xibao as well.

At the same time, the distance from here to Daliang City is only more than [-] miles, that is to say, the Wei Yuan army can arrive in half a day, and the navy army even only needs an hour.

You must know that Qin Jun planned to attack Daliang by water.

If Wei Jun sticks to this water inlet and sends reinforcements continuously, I am afraid that Qin Jun's strategy will be aborted before it starts.

But Wei Bing still withdrew cleanly, leaving only a pile of burned houses and trebuchets.

The structure of the small fort is very complete and has not been damaged at all.

Shen Bing guessed that this should be because Wei Jun thought that Qin Jun would return without success in a short time, so he was reluctant to destroy the small fort, and only waited for Qin Jun to retreat before returning to receive it.

It's a pity that these Wei Jun didn't understand what was going on at all. The castles they gave up may never return to their hands.

Shen Bing's engineering troops were divided into two and temporarily stationed in these two small forts.

Zheng Guo also arrived with his group of hydraulic engineers... Their task was to survey the hydrology of the estuary.

Then Yang Duanhe and his personal guards camped nearby.

There is no other reason. This Guangwujian is the first section of the water attack, which is the interface between the Bianhe River and the Yellow River. It is related to whether the water potential is large enough to destroy Daliang City.

Shen Bing was sent as Zheng Guo's assistant to follow the survey, but Shen Bing didn't know much about hydrology, he just watched Zheng Guo and his party take a small boat there to measure the current velocity and water depth, and occasionally dived into the water to measure silt and the like.

After half a day, Zheng Guo had an idea in his mind, and several people gathered in Yang Duanhe's handsome tent to discuss.

"How?" Yang Duanhe asked, "Is water attack feasible?"

Zheng Guo replied:

"As expected, the estuary is seriously silted up. If we want to attack the river, we must first dig out the mud and remove the silt."

Yang Duanhe replied:

"It's not too late for such a thing, the water engineer just issues an order, and I'll start dredging right away."

Zheng Guo hesitated for a while, then said:

"I'm afraid it's not as simple as the general thought."

Yang Duan and Qi said:

"Why?"

Zheng Guo spread out a hydrological map in front of him and said:

"Please look, general, your subordinates have divided the desilting into three sections."

"The first section is Guangwu Stream. We will widen the mouth of the stream and remove the silt at the bottom of the river, so that the water volume will be sufficient and the water will be turbulent."

The mouth of the Guangwu stream was deliberately filled with rocks by the Wei people. This was not to prevent the Qin army from flooding, but to control the amount of water... When the Yellow River flooded, too much water flowed into the Bian River, so the Wei people used rocks to block the mouth of the stream. .

At this time, if the Qin army wants to attack by water, the stronger the water force, the better, so these rocks must be cleared.

"The second is the middle section." Zheng Guo continued:

"It is only necessary to clear the silt at the bottom of the river here."

"The most difficult thing is the third place... This section of the river is close to the Wei Army's Daliang City. How can we clear the silt under the enemy's city?"

Yang Duanhe couldn't help frowning when he heard this, and asked:

"Does this section of the river have to be dredged?"

Zheng Guo replied:

"Although I haven't conducted a field survey, I can judge from the trend of the river course and the degree of sedimentation at the bottom of the river..."

"If this section of silt is not removed, the river may overflow before rushing into the girder."

"At that time, the water attack on the beam will only turn the large field outside the city into a swamp, and it will be even more difficult to attack the city."

What Zheng Guo said is authoritative, so Yang Duanhe couldn't help but not believe it.

But as Zheng Guo said, dredging under the city wall?

How to desilt?

Never died?

A random row of arrows shot from the top of the city can cause heavy casualties to the dredging Qin army.

So there is such a question:

If the third section, that is, the section under Daliang City, cannot be dredged, is it necessary to clear the other sections?

If the other stages are cleared, and in the end it is still impossible to attack Daliang City because of the third stage, wouldn't that be a useless effort?

After a while of silence, Yang Duanhe said:

"Perhaps, we can take advantage of the night to clear the silt."

But even Yang Duan and himself feel unreliable when they say this.

That is the moat under Wei Jun's city. Even if Qin Jun didn't light torches, Wei Jun threw a few torches down at random, and then there was a rain of arrows... How many soldiers of Qin Army would be killed or injured to clear this section of mud?

And that's just one of the difficulties.

Then Zheng Guo said another bad news:

"I may only have more than ten days to wait!"

"If it can't be done in more than ten days, I'm afraid it will have to wait until the beginning of spring next year."

Yang Duanhe asked puzzledly:

"Why is that?"

Zheng Guo pointed to the hydrographic map and explained:

"The upper reaches of the Yellow River are located in the north, and the weather in the north is cold, so it will freeze."

"If the upstream freezes, the amount of water in the river will decrease sharply, and then..."

Shen Bing has some understanding of this aspect. The Yellow River has a very peculiar phenomenon called "Ling Xun".

"Ice flood" occurs on rivers flowing from south to north.

After winter, the river in the north will freeze, and the river in the south will continue to flow down and be blocked, causing floods.

This is also the reason why the Yellow River floods at every turn. It may flood all year round, and the time is not fixed. For example, the flood season in winter is related to temperature and cold currents.

The reason why the Yellow River is called "strange" is that its channel is in the shape of "ji".

So there will be ice flood phenomenon in two positions.

The first section is at the beginning of a few characters, and the frozen location is in the Hetao Plain, which is the northern land under the original Zhao Kingdom Li Mu.

The other part that will be frozen is the hook at the end of a few words, which is located in the Jinkou area of ​​Yan State.

The northern lands were frozen first, so there was less water in the middle and lower reaches during this period.

Only when the temperature rises in the north next spring and the ice and snow melt, the water volume will increase again.

So Zheng Guo said, if it can't be completed in more than ten days, I'm afraid it will have to wait for the spring of next year.

134章 沙袋

Can't wait until next spring.

It's not that the Qin army can't besiege the city until next year, but that there are too many variables in it.

Will the Chu army come to help during the siege?

Did King Wei change his mind and go out to fight in the city?

If Chu and Wei unite, then Qin Jun may really be unable to deal with it.
