At this time, the Ministry of Industry organized a large number of people and was rapidly reinforcing the river embankment.

But in Li Su's view, doing this is just doing a job, but for the overall situation, it doesn't help at all.

In desperation, Li Su couldn't help but call up the system and asked in his mind: "System, do you have a way to keep the river from breaking the embankment?" ”

"Nope!"

Damn, is it so crisp?

Although Li Su also knew that his system was very unreliable, he didn't expect it to be unreliable to such a point.

Isn't it all about other people's systems, what they want, what they want, and what they can do?

How did you get to yourself and the system became so wasteful?

Alas!

Next, Li Su had to figure out his own way.

Li Su rode his horse and continued to walk upstream, but he didn't go far when he suddenly saw the channel in front of him.

Chang'an City is known as Chang'an City of Eight Waters, and there are eight rivers around the city, which is rich in water resources.

This time, it was also because of the abundance of water resources that the flood occurred.

In Chang'an City, from these rivers, five canals have been drawn, namely Qingming Canal, Longshou Canal, Yongan Canal, Yellow Canal, and Cao Canal.

The introduction of these five canals has made life in Chang'an more convenient and transportation more convenient.

The canal has been closed after heavy rains caused the river to swell.

If it is not closed, I am afraid that at this time, Chang'an City will also become a water.

However, after seeing this canal, Li Su's heart couldn't help but move.

I couldn't help but ride my horse and continue upstream, and after a while, I saw a canal again.

The topography here happens to be a large section of narrow river in the middle.

If the two channels were opened to divert the river from Chang'an City, would the danger of the embankment bursting be solved?

Of course, this is very dangerous.

Because of a careless word, the river embankment may not burst, and Chang'an City will be flooded directly.

And the sin of drowning Chang'an City is far greater than the breach of this river embankment.

And now, after this method, Li Su has no choice.

After thinking about it, Li Su couldn't help but call up the system again and asked: "System, help me calculate, if I reopen these two canals and let the river flow through these two channels." ”

"What are the chances that this section of the embankment will survive? And will Chang'an City be flooded by the river? It's no problem to calculate this data, right? ”

The system couldn't help but say: "To calculate these, it requires a huge amount of computation, and it needs to charge a thousand loser values, does the host want to calculate?" ”

"Calculate!"

It's good to be able to calculate, what Li Su cares about now is not the value of the loser at all.

Then, Li Su only listened to the system's calculations: "Now, the flow speed of the river is 23 meters per second, the depth of the river is 3.6 meters, and the number of cubic meters passed per second is ......."

it!

Li Su said with black lines on his head: "I don't need to listen to the process, just tell me the result." ”

"The result of the system's calculations is that this section of the embankment can be saved, but Chang'an City will inevitably be flooded, and the water level is about half a meter deep."

Hearing that Chang'an City would inevitably be flooded, Li Su couldn't help but gasp.

However, when he heard that the water level was half a meter deep, Li Su's face began to be gloomy and uncertain.

When the time comes, most of Chang'an City will be soaked in water.

The houses of the common people, there will definitely be some old houses that will be soaked and collapsed.

Now, on one side is the safety of tens of thousands of people.

Once the levee breaks, the lives of these tens of thousands of people will be in danger.

But even if all these tens of thousands of people died, his fault was still a small mistake.

On the other hand, the people in Chang'an City may only have hundreds of casualties, or even less.

However, if he made such a choice, he would inevitably face a terrible punishment.

Because, this is the capital, and there is a palace here!

How to choose?

Where do we go from here?

For a moment, Li Su couldn't help but fall into deep thought.

After a long time, Li Su finally made a decision!

"Come on, open all these two canals!"

At this time, the eldest grandson Wuji, Fang Xuanling, and Du Ruhui, who came to the front line of the dam, didn't they see this?

They knew in their hearts that if these two canals were opened, it would be possible to keep the downstream section of the embankment.

But opening two canals would be a great disaster.

They don't have a system and can't calculate exactly where the water level will go.

What they are even more afraid of is that it will flood most of Chang'an City, and the people in Chang'an City will suffer countless casualties.

If that's the case, then they'd rather let the dams downstream be washed away.

Therefore, after hearing Li Yu's order, the eldest grandson Wuji was the first to say: "King Liang, no!" I know that you are dedicated to the people. But the consequences of opening a canal are extremely serious, and we simply can't afford it! ”

The eldest grandson Wuji actually hates Li Su very much, but at this moment, the words of the eldest grandson Wuji are really good to Li Su.

In the heart of the eldest grandson Wuji, first of all, the Jiangshan Sheji of the Tang Dynasty, and secondly, it is the personal grievances, and he is very clear about this.

After the eldest grandson Wuji, Fang Xuanling and Du Ruhui also persuaded each other.

And those officials of the family are bright-eyed, looking forward to Li Su giving this order.

Once this order was issued, they had an excuse and a reason to impeach Li Su.

When the time comes, they will attack it in groups, and they will not believe that they will not be able to defeat this King of Liang.

And Li Su said in a deep voice: "Everyone, I know what I'm doing, for the safety of tens of thousands of people, I did this!" What are the consequences, I will bear it alone! ”

After that, directly order those soldiers to open the two channels.

At this time, no one persuaded him anymore.

However, the officials present had different expressions and were in very complicated moods.

After a short time, the two channels were opened.

The raging river poured down two channels.

Because of the diversion of two canals, the river below suddenly eased a little.

The impact on the river embankment has also weakened a lot.

This relieves a lot of the burden for reinforcement work.

At this time, however, the river was raging between two channels.

In the river, a large number of fallen leaves and dead branches fell into the river, although some people were constantly salvage.

But after all, there were still blockages, and the raging river water was pouring in, which already exceeded the maximum capacity of the two canals.

Therefore, soon the river water will flow along the channel to the entire Chang'an City.

And because of the heavy rain for days, there was already a lot of water in Chang'an City.

Originally, this stagnant water flowed into the canal and was carried out by the canal.

But now, there are two aqueducts overflowing with water.

As a direct result, there is a lot of stagnant water in the city, and there is no place to drain it.

It also caused the water level in the city to become higher and higher.
