That night, there was a sudden heavy rain, which continued until late at night and still had no intention of stopping.
Suddenly, a huge thunder and lightning sound rang out, awakening Qing Cang.
At the same time, the guard's voice came from outside the door.
The guard's voice seemed very urgent, so it seemed that something serious must have happened.
"The commander is in trouble, the commander is in trouble" As soon as Qing Cang opened the door, a guard rushed in dripping wet with a panicked expression. .
"What happened so you are so panicked?"
The guard agreed: "It rained suddenly tonight and has lasted for more than three hours.
Now the water level of the moat has risen rapidly.
The water level is only four feet above the ground and the water is still rising.
The king ordered me to come and ask the commander, saying that something must be done.
Emergency measures, otherwise the river will flow back and directly damage the city wall.
He said that the suspension bridge will also cause some damage. " Four feet is very close to the height of the ground, and this height sends a dangerous signal.
Once the city wall is soaked in water, it will inevitably be damaged.
With a powerful enemy in front of him, he must prevent this from happening.
During flood fighting and disaster relief, he assisted the disaster-stricken areas many times.
He was once appointed as a squad leader, and as a squad leader, he commanded hundreds of soldiers to fight floods and provide disaster relief.
So he knew exactly how to deal with things like floods.
"Order the entire army to be on standby and summon all military officers and civilians in the city to assemble in the council hall immediately.
I want to organize disaster relief."
This is a big deal.
If your wall collapses before the enemy comes, then everything will be in vain.
There is no such thing as cement in ancient building materials.
Most buildings will suffer major or minor damage when exposed to rushing water.
If one piece of the city wall collapses, it will cause a chain reaction.
When the time comes, the city wall will not be attacked. self-destructive.
That's nothing.
Without the protection of the city wall, the Chinese Legion will have to fight the enemy hard and will inevitably lose a lot of soldiers.
The guards immediately went down and prepared to call everyone in the main city, as well as some generals at the military camp.
After a while, the entire meeting hall was brightly lit, Qing Cang's expression was solemn, and now everyone was present.
Even Wang Zongwei hurried back and waited for Qing Cang's dispatch.
At this time, the heavy rain was still falling, and there was a loud crash.
Fortunately, the previous paper machine was lifted onto a high platform and covered with a movable greenhouse, so it did not touch any water, otherwise he would have cried.
Because it costs a lot of life points to exchange.
Without it, paper money cannot be produced, and the entire economic circle may fall into chaos.
Qingcang said: "Wang Zongwei, tell me what the current situation is like."
"Back to the commander, the heavy rain continues and the water level rises sharply.
In less than an hour, the force will flood the moat.
If we don't respond in time, it will only take an hour for the water to spread to the foot of the city.
I'm afraid that if the water erodes, it will do something to me.
The square wall caused huge damage."
"Where does the water come from?"
"Because the west gate is higher and the north is lower, all the river water flows towards the north gate, so the danger at the north gate is the greatest.
There are also many waterways in the city that drain to the moat, and the other three gates are also in danger."
According to Wang Zongwei's instructions, Qing Cang paddled on the sand table.
Guo Jia made suggestions: "I think the water is coming quickly.

We must solve the problem from the source and guide the water to other places.
In this way, the problem will be solved."
Qing Cang agreed.
"Well, this suggestion is feasible."
"I haven't thought about how to divert the water yet.
Maybe we can mobilize the army to dig canals to divert the water."
The source of the moat is under a mountain spring, and the water is drawn from there, so Guo Jia means to start from there.
After all, Wang Zongwei is already very familiar with the project, so his words are very practical.
He said: "It is very difficult to dig a channel in an hour, and because the water is flowing, it may put soldiers in danger. " People suddenly fell into anxiety, what should they do?
Everyone discussed: "Then we have to do something."
"If the whole army goes out to dig channels, it should be completed in a short time."
"No, this is not a question of the number of people.
No matter how many people you have, the width of the channel is limited, and the number of people it can accommodate is also limited.
Although the efficiency can be improved, the scope of improvement is still limited.
Didn't Minister Wang say that one hour is still Not enough.”
"What should I do?
I'm so anxious."
Everyone had absolutely no choice but to pin their hopes on Qingcang.
"The commander must have a solution, right?"
"Yes, the commander can think of anything we can't think of.
He must have a way."
Qingcang had been thinking about other issues just now.
At this time, he finally spoke and the whole place became very quiet.
"Mr.
Zhao, you take 50,000 people to fill the bags with sandbags.
The more sandbags, the better.
Mr.
Zhang, you take 30,000 people to dig channels at the source of the spring water.
The sooner the better, the purpose is to divert the water away.
The rest I will take the lead of the 30,000 people, and Minister Wang will assist me in transporting the sandbags to the west gate."
Zhao Zilong, Zhang Liao and Wang Zongwei should be the Someone asked about this.
"Commander, what's the use of sandbags?
Why don't we go directly to solve the source of the problem?"
Qingcang gestured on the sand table and said: "Stacking sandbags can raise the height of the river embankment and increase the water storage level to prevent water from flooding into the city.
This can only be temporary.
If the water potential is greater, then the sandbags The effect is zero.”
Everyone looked at it very seriously at first, seeming to understand but not understanding.
Later, he showed how to stack sandbags, and everyone understood his intention.
In the introduction to civil engineering, it is said that earth-rock dams are most afraid of overflowing.
The water flow caused by overflowing the dam will take away the earth and rocks on the dam surface.
As the earth and rocks become moist and reduced, the bearing capacity of the dam surface will decrease.
Moreover, it will increase the probability of piping.
Once a piping occurs, the earth-rock dam will collapse rapidly.
River embankment is also a kind of earth-rock dam.
Sandbags play an important role in strengthening the dam and preventing it from overflowing.

It has a certain role in raising the height of the river embankment, but the above-mentioned things are too profound, and no one can understand it when he talks about it.
It is better to talk about a relatively simple principle.
So someone asked: "How long can this method last, Commander?"
"One and a half hours at most.
It's not too late, you guys take action."
In this way, it would take two and a half hours, five hours, for the water to reach the city wall.
By then it would be daybreak.
It shouldn't be difficult to dig a small channel in five hours.
Zhao Zilong and Zhang Liao took the orders and took the generals under their divisions to their respective destinations.
Bai Yu and Twelve were not in a hurry just because they had just entered the military camp.
They responded in time and joined the tension with the two senior commanders.
Go to the rescue.
Because this time will be their perfect opportunity to perform.
As for Wang Zongwei and Qing Cang, Qing Cang must be the commander-in-chief this time.
In addition to doing rescue work, I can only pray to God to stop the rain
