Daqin Engineering Corps

Wang Jian was a little confused, and asked his son the reason, and his son replied:

"If you 'cut' horizontally and then 'cut' vertically, the melted water will flow into the horizontal groove and freeze again."

"There will be a lot of trouble if you repeat it like this."

"Only when the horizontal and vertical operations are operated at the same time, the water will be continuously discharged from the ditch."

Wang Jian couldn't help nodding his head when he heard the words.

All walks of life have their own proficiency, and it is true to say that every industry is like a mountain.

After two full days of tossing around the big bend, Nu was very careful when "cutting" up.

Every time, after all the preparations are done, all the idlers are evacuated, and then a few quick-moving people are sent to ignite the fire quickly.

Taking a final look at the situation, Nuo reported to Wang Jian:

"General, it's the last moment to break the ice and drain the water."

"Should I drain it now or wait a few days?"

This question is whether the military and civilians downstream have been notified to make full preparations.

You must know that the lower reaches of the river are also blocked by freezing at this time, and it is not a joke to release the water that has been accumulated for more than a month.

Wang Jian thought for a while, then asked back:

"Will there be any problems if the drainage is delayed for a few days?"

Nanny replied:

"The subordinates can't guarantee it."

"The reason is that the weather is cold and warm and cannot be estimated."

"If it suddenly turns cold and the upper reaches of the river freeze again, I'm afraid it will take a lot of effort."

Wang Jian can understand this.

Wang Jian was not worried about time.

Because the food in Daliang and Handan can last for several months.

What Wang Jian was worried about was that if he let go of this chance of drainage, maybe there would be no next time.

For example, when a cold current suddenly came and three miles were frozen, after Qin Jun tossed for a few days to "cut" the three miles and then freeze five miles...

The weather will definitely be colder as the time goes on, and it is conceivable that the freezing speed will be faster.

If the speed of digging ice cannot keep up with the freezing, all the work will be in vain.

But if you say prepare...the downstream is definitely not ready.

It doesn't matter much in Handan.

Handan has set up a beacon tower, and as soon as a flood is found upstream, an early warning will be issued, and the troops will withdraw to the high place where the grain has been stored.

The problem is with the girders.

Before, Ying Zheng agreed with Daliang for two months in order to have enough time.

But now it only takes a month to divert water, I'm afraid...

Wang Jian made a balance in his heart:

If you don't release the water now, you may never be able to release it, so you will lose everything.

And now Daliang City may suffer losses due to insufficient preparation, but it is obvious that the losses of the Chu army surrounded outside the city will be even greater, and there is basically no suspense for the Qin army to win.

This comparison Wang Jian thought that there should be no further delay, so he ordered immediately:

"Drain water at this time!"

The son responded, and waved a small flag to send a signal to his subordinates.

With a sound of "Teng", fires were ignited everywhere.

The ignition this time is different from the previous ones. There were neat "cuts" before, but this time it was concentrated in several places on the embankment.

Nun explained:

"This is like digging a few gaps in the embankment."

"The cracks in these gaps will connect to each other, and the entire ice bank will collapse!"

Sure enough, just as Nuan said, not long after the fire was lit, there were bursts of crackling sounds on the ice.

It rang for a while and then fell silent again. Just when everyone was wondering, suddenly several huge pieces of ice flew into the air, and the flying pieces of ice even hit Wang Jian's hiding place dozens of steps away on both sides of the bank, scaring all the guards He hurried forward to protect Wang Jian.

This situation was obviously beyond Nu's expectation, which only scared him to hide behind the tree.

Then the ice layers were layered on top of each other like dominoes, and the sound of collisions was endless.

Soon there was a sound of "teng", and a stream of water poured down like a fountain. The water column became bigger and bigger, and soon mixed with debris, and it was hard to tell which was water and which was ice.

The water line quickly spread to both sides of the bank with debris, only to scare the soldiers to flee in a hurry, and a few who ran slowly were swept in and disappeared in an instant.

It took a while for Nu to come back to his senses, and reported to Wang Jian in shock:

"General, it's done, the water diversion is done!"

Wang Jian nodded.

As the saying goes, it is up to people to make things happen, and now it depends on whether the rushing river can work.

Of course, Shen Bing on the other side didn't know that the river was coming.

At this time, the morale of the troops was much better than before.

This is a kind of inertial thinking of people.

At the beginning of the change, that is, when the Qin army was just surrounded by the Chu army, it would be tense for a while.

But as the days passed, they found that being surrounded was just like that, and then they took it for granted that the days to come would be similar, so they soon stopped caring.

Only Shen Bing knew that this was the beginning of the crisis.

Fortunately, I have found a solution, but I don't know how Wang Jian's ice digging upstream is going.

In order to prepare in advance, these engineers are making rafts again... The previous rafts were dismantled to make trebuchets due to lack of wood, and now they are dismantling the collapsed houses in the city to make rafts, which is a bit of a mess.

Cang asked strangely:

"Brother, why do you want to make rafts again?"

"Could it be that the Chu army wants to attack Daliang with water?"

Shen Bing did not tell him the answer, but confessed:

"Do your job well, don't care about Chu Jun."

"You are already an engineer, and you have more than a hundred people under your command, and they all follow your example."

"If you're negligent... I'm afraid even Chu Jun won't be able to see you!"

Cang responded and didn't dare to say anything more.

152章 水德

At this time, there was a commotion outside the city, and then someone shouted from the top of the city:

"Water, flood! The flood is coming! . . . "

At that moment, Shen Bing's head slowed down by half a beat. Could it be that the upstream has already dug ice to release water?

It can't be!

The agreed time is one month later!

But after thinking about it, Shen Bing felt that this was normal.

Ice chipping and drainage is not so easy to control.

If this is relatively easy in modern times, once the explosives are loaded into the ice layer, it can be detonated whenever you want.

But in this era, it is almost dependent on manpower to dig ice. If you accidentally cause a chain reaction in the ice layer, won't the whole crack open and the water will flow down?

Thinking of this, Shen Bing felt relieved.

Then Shen Bing became excited again, as soon as the flood came, the Chu army would be finished, and the siege of Daliang would be lifted...

At this time, Yang Duanhe hurried over just after getting the report, and when he saw Shen Bing, he nodded to signal to follow.

Shen Bing didn't dare to hesitate, he put down his work and followed Yang Duanhe to the top of the city.

Climbing to the top of the city and looking down from a high position, the flood outside the city has indeed overflowed. The most obvious thing is the moat. The Guangwu Stream upstream of it has been blocked by Zheng Guo with rocks, but it is still flowing at this time. There was a creaking sound, and it was obvious that water from other directions had gathered into the river.

Looking farther away, the Chu army barracks was already in chaos, with shouts, shouts and horses neighing. Standing on the top of the city, although they couldn't see the water, they could see the Chu army retreating southward in a panic.

The Qin army ruled the army strictly and did not move much, but the army flag waved wildly to seek orders.

Without hesitation, Yang Duanhe immediately ordered:

"Withdraw troops and return to the city!"

"Open the gates!"

The city gate opened slowly with a "squeak", and then the Qin army rushed into the city like a tide.

However, the rising speed of the water flow was much faster than the retreating speed of the Qin army. After a while, the water in the moat overflowed the suspension bridge and poured into the city, and the momentum seemed to be still rising.

In a hurry, Shen Bing turned around and shouted:

"Hemp rope, wood!"

Although the craftsmen didn't understand what Shen Bing wanted these things for, they still responded and moved the hemp rope and wood to the city wall.

Shen Bing didn't say much, took a piece of hemp rope and tied one end to the parapet wall and the other end to the log and rolled it down the wall... The wood was thrown into the water and floated at the foot of the wall.

At that moment, several soldiers struggling in the water hugged the wood and poked their heads out, gasping for breath.

The weakness of the soldiers of the Qin Army is that they can't swim, and they are fully armed so it is difficult to survive in the water. This is considered to be a life-saving straw.

Everyone immediately understood what was going on when they saw it, so they tied logs and boards and hung them down the city wall one after another like Shen Bing.

It's just that someone threw the stick too hastily, hitting several heads on the spot with one swing of the stick, Yang Duanhe was so angry that he cursed.

Fortunately, the water comes and goes quickly... This is mainly a flood peak rushing down from the upstream. Due to the excessive momentum, it was unable to change direction at the big bend of the girder before rushing ashore.

After half an hour, the flood peak gradually became smaller.

Those Qin soldiers who had been washed to pieces entered the city in groups of three or five, but they were all shivering from the cold with only half their lives left, and many corpses were left outside the city.

Yang Duanhe was not angry but happy, because if the Qin army outside the city was rushed like this, what about the Chu army with more people and no city walls as their strongholds, all tents?And what will happen to the food and grass of the Chu army?

Yang Duanhe was right in thinking that the Chu army camp had been smashed to pieces.

Not to mention the tents, they were uprooted as if swept by a hurricane.Grain and grass were washed everywhere, there were bags here and piles there, some were washed into the river or scattered all over the ground, and none of them could be recovered.

This is only the case in the direction of the girder.

The focus of the flooding was the main force of the Chu army between Handan and Daliang.

The flood in this area is not just a flood peak passing by.

As mentioned before, the frozen river water in the Jinkou area cannot be released and accumulated in the upper reaches of Handan.

Originally, because the amount of water in the middle and lower reaches was not large, it was not a big problem to store it, but at this time, the amount of water suddenly increased, and the water storage doubled and spread to both sides of the bank in an instant.

For a time, there was a piece of Heze south of Handan that lasted for a long time.

The Chu army has sailors in this area. Most of these sailors are small boats used for ordinary operations. How can they withstand the flood peak? .

As for the infantry, those who can run fast will concentrate on the nearby high ground, and those who cannot run fast can only flop around in the gradually rising water... Although the Chu army mostly swims, they are still wearing armor in such a sudden situation. Even being able to swim won't save them.

So in a short time, countless dead and wounded corpses littered the field.

Only then did Yang Duanhe order the navy to attack...

The navy of the Qin army cannot actually be called a navy. They are just infantry on rafts. Many of them can't even swim and fall into the water to be rescued.

If it was at other times, such a navy would certainly not be able to compete with Chu's navy.

But now is not "other times", when the Chu army has no water and the infantry is flooded.
