Emperor Renxuan was stunned for a moment when he heard this, and then just shook his head helplessly.

If Gu Beichuan's previous series of words are still somewhat credible, then the last sentence is pure nonsense.

What is the Canglan River?

Daqian's mother Jiang!

The total length is more than 6,000 kilometers, and the river basin is close to one million square kilometers!

Even the entire territory of the Great Qian, only one-third of the Canglan River.

But even this third is called the past and present, and in the past three hundred years, countless famous people in water control have sighed and changed their colors.

And who is Gu Beichuan?

I have to deny that this kid does have some talent.

If it is about writing poetry and lyrics, he is an expert among experts.

When it comes to business, he is also a good hand.

But...... Has he ever been on a field trip?

Have you ever been to the riverside to see the surging river?

None of this has been done, and with his age of not being crowned, there is really no credibility to say this.

Even if Emperor Renxuan admired it, at this moment, he just laughed at it.

Gu Beichuan didn't seem to notice it, but instead came to talk about sex, and told the many understandings he had from the book of the vicissitudes of waters.

"In my opinion, if you want to deal with the Canglan flood in this small section of the river basin of Canglan County, the main energy should not be on Canglan County, but on Tianyuan County, which is not far from it!"

When Emperor Renxuan heard this, he raised his eyebrows, and his heart became more and more helpless.

Listen to what this is saying.

kept saying that you should prescribe the right medicine, but it turned out that it was Canglan County that was sick, but you had to run to govern Tianyuan County.

If he remembers it well, although Tianyuan County has always been bitterly cold, there has never been a flood in the Canglan River!

Isn't this kind of "prescribing the right medicine" nonsense and making it laugh in vain?

It's just that seeing that Gu Beichuan was in high spirits, Emperor Renxuan didn't interrupt him.

"Why?"

"This is going to start with the cause of Canglan County!"

"Whether it was the period of the first emperor or the period of Wuzong. So many capable people with lofty ideals once wanted to control the Canglan River, and implemented various measures such as diversion and diversion, blocking and dredging, all of which were not satisfactory. ”

"And why?"

"It's just because of the river basin near Canglan County, there is a big problem!"

"The riverbed is too high!"

"Whether it's dredging or diversion, once the embankment is moved, such a high water potential will be the sky tilting as soon as it leaks down!"

"Therefore, if you don't solve this problem, it will be in vain to come up with more solutions."

Hearing this, Emperor Renxuan's eyes became brighter and brighter.

Because what Gu Beichuan said is exactly what the imperial court has been worried about all these years!

Over the years, the embankment of the Canglan River has been repaired again and again, and now it is several times the height of ordinary buildings.

With such a high water level, the dry period is fine, and it can still be managed.

If it is the flood season, it will be a monstrous flood, and it is really a fool's dream to try to control it.

In the case of the Canglan flood, Emperor Renxuan thought that he would give up if he raised enough money and food for disaster relief.

Immediately afterwards, a holy decree was issued, ordering the people of Canglan County to temporarily evacuate and find another place to go during the flood season.

It's really not good, the court will give them another batch of money to repair the house.

Such a method, Emperor Renxuan also knows, is to treat the symptoms but not the root cause.

It's just that...... What can I do about it?

The water potential of the riverbed is too high, and it is clearly an unsolvable problem!

But now, listening to Gu Beichuan's words, it seems that there is a solution.

Doesn't that mean...

His eyes suddenly lit up, and he urged, "Go on!" ”

"I still say the same thing, everything must be the right medicine."

"If you want to solve this problem, you have to find the lesion!"

"Ordinary rivers, no matter how high the terrain is, it is only a small section high."

"Where is there such a river like Canglan River, the water level of the riverbed around Canglan County is frighteningly high, and it is not an exaggeration to say that the river is in the sky!"

"There must be demons when things go wrong, which shows that the high water level in the Canglan River Basin is not innate, but acquired."

"So how do you get the water level higher and higher? Without him, add mud and quicksand to the water! When they sink to the bottom, the water level will naturally rise. ”

"You mean, someone poured a lot of sediment into the basin?" Hearing this, Commander Pei was unwilling to be lonely and expressed his "insightful opinions".

When Gu Beichuan heard this, his eyes were like torches, and he nodded: "Not bad!" ”

Yes?

As soon as these words came out, even Pei Bu let himself be stunned.

What he said just now was just to see that the atmosphere was a little serious, and he teased one or two, and by the way, he just showed his sense of existence.

This... Why are you still serious?

Someone poured sediment into the Canglan River Basin?

How much does this have to be?

Don't say that he is just a suspected celestial, even if he is a celestial, and the element of heaven and earth that communicates is still an earth attribute, it is impossible to dump enough sediment to make the water level in the Canglan River Basin rise!

That's an astronomical amount that makes everyone feel smacked!

Besides, if you are a dignified person, if you want to kill people, you just have to start a big killing, and launch an offensive with the power of heaven and earth, even if it is to slaughter thousands of ordinary people, it will not take much time and energy.

Pei Burang felt that not only did he not enliven the atmosphere, but made the atmosphere of the scene more serious, and he was suddenly a little embarrassed, so he became silent and stopped talking.

When Emperor Renxuan heard this, he couldn't help shaking his head, and a little disappointment appeared in his heart.

I didn't have much hope, but... What if?

If Gu Beichuan can really solve the flood, it will be a great achievement! It is undoubtedly the solution to his immediate urgency!

It's a pity that in the end, the children who have never reached the crown are talented, talking and doing things, but they are all immature.

The reason for this is really no different from that of a child.

Someone poured sediment into the Canglan River? How did you come up with this?

Emperor Renxuan wanted to sigh, but before he could sigh, he heard Gu Beichuan continue: "It's just that this dumping of mud and sand is not a person, but Canglan River itself!" ”

Well?

Pei Bulet was dumbfounded, and Emperor Renxuan frowned, all of whom did not understand Gu Beichuan's words.

"Imagine if there is sediment in the upstream of a river, will the sediment fall upstream or downstream?"

"Naturally, it's downstream, after all, the river flows." Pei Burang couldn't hold back and took the initiative to speak.

When Emperor Renxuan heard this, his eyes lit up, he seemed to think of something, and asked sharply: "Then where does the sediment in the upper reaches come from?" ”

"This brings us to the question I said at the beginning - Amahara-gun! The sediment in the Canglan County basin is all the soil brought by the river from Tianyuan County! ”

"Soil? The river is good, and the riverbed has not collapsed, so why does it bring down so much soil. Doubts rose in Emperor Renxuan's heart again, and the light in his eyes faded.

Gu Beichuan's logic still doesn't make sense.
