When Emperor Renxuan heard this, he couldn't help but feel regret in his heart.

To tell the truth, there was only a moment in his heart that he really had hope that Gu Beichuan could solve the Canglan flood.

It's a pity... In the end, this logic still doesn't make sense.

The soil, as we all know, is very compact.

Otherwise, how can we afford to stand on top of a large living person?

Even if it is washed by the turbulent river, it will not collapse in a short time.

If it takes a long time, it will indeed wash away some of the soil.

But certainly not much!

It is impossible to reach the point where the riverbed in the Canglan County basin is raised!

After all, that's an astronomical amount that everyone can smack!

Therefore, in the final analysis, Gu Beichuan's words are still illogical.

Fallen on the most critical part!

It seemed that he saw the regret in Emperor Renxuan's eyes, but Gu Beichuan didn't care, but asked, "Your Majesty, do you know the difference between this Tianyuan County and the surrounding counties?" ”

When Emperor Renxuan heard this, he was slightly stunned, recalled the report about Tianyuan County in his mind, and slowly spoke: "In a bitter cold place, it is windy all day long. ”

When Gu Beichuan heard this, he smiled with satisfaction and said, "It's this wind that is bad!" ”

"What's wrong with the gale? The gale really made the people of Tianyuan County miserable, and when it was the most serious, it could even destroy the house, which was a big disaster, but what did the gale of Tianyuan County have to do with the river basin of Canglan County? ”

"It's something that can't be beaten by eight poles!"

"No, there's a lot at stake here!"

Emperor Renxuan became more and more puzzled, but Gu Beichuan's eyes became brighter and brighter the more he spoke, as if he contained light.

"Brother, think about it carefully, why is the soil so compact?"

"It's because there's water in it!"

"There can be neither more nor less of this water, for if it is too much, it will become a thin mud. If it's less, it will become the soil of Tengahara County! ”

"The soil of Amahara-gun? How is it different from elsewhere? Emperor Renxuan frowned, although he was the emperor and held the throne, it was impossible for him to personally inquire about many matters in each county.

Therefore, I only have a general impression that the soil of this Tianyuan County is not fertile and difficult to cultivate, coupled with the wind disaster, so it has been very poor for many years, and the imperial court has to reduce a lot of taxes for it every year.

As for the specific problem with this soil, I don't know.

"Brother has dried clothes on weekdays?"

"You know, drying clothes in a windy place is much faster than drying clothes in a normal place."

"What's the explanation?"

Emperor Renxuan was stunned again when he heard this, wasn't he still talking about the soil of Tianyuan County just now? How is it so good to talk about drying clothes again?

He is a dignified emperor, and the dragon robes and crowns on weekdays are all taken care of by the palace eunuchs.

Therefore, I really don't understand this matter of drying clothes.

So he turned his gaze to Pei Burang, although Pei Burang was also in a high position, he didn't even see him drying clothes.

At this time, Emperor Jianren Xuan saw that his time to perform had come, so he immediately patted his chest and said arrogantly: "There is such a reason. ”

The pride revealed in his words was as if he was not a commander of the forbidden army, but a Confucian and Taoist who studied heaven and earth.

It seems that what I just said is not a short matter of parents such as drying clothes, but a shocking truth and knowledge.

But fortunately, during this period of time, Emperor Renxuan was used to seeing Pei Burang's toss, so he didn't take it to heart, but nodded towards Gu Beichuan and said, "Even so, what can it mean?" ”

"There's so much more to explain here."

"First of all, we have to figure out why, why it is so much faster to dry clothes in a windy place?"

"Because this wind can take away the moisture in the clothes!"

"In the same way, Tianyuan County is windy all year round, and the moisture in the soil is naturally taken away, and it becomes a ...... Wind and sand! ”

"Wind sand? What is aeolian sand? Emperor Renxuan asked with a frown.

"That is, the particles are small, not sticky, like dust!"

Rumble!

As soon as these words came out, a certain string in Emperor Renxuan's mind seemed to be clear!

Gu Beichuan said a lot of nonsense about him left and right before, but at this moment, they were all connected in his mind!

It's like dust!

Although he is a pampered emperor, he probably still knows what the dust is.

That thing, the wind can easily blow!

After blowing, if you reach the surface of the Canglan River, it will condense into a lump and fall into the river when it encounters water vapor.

In the end, this sediment that should have fallen in the basin of Tianyuan County was all sent to Canglan County because of the flow of the river!

This led to the phenomenon of the Heavenly River mentioned by Gu Beichuan!

It is precisely this phenomenon that has tormented Daqian for hundreds of years, and has stumped many capable people who control water!

But now, this reason has been figured out by a young man who has not even reached the crown!

It's really... What a blessing for me!

In Emperor Renxuan's heart, he was surprised and delighted at this moment.

No wonder Fang just said that those predecessors had never found the right lesion, so it was just a waste of effort.

The source of the flood in the Canglan River Basin is in Tianyuan County!

How can one imagine this? It's not in vain to have ghosts!

Emperor Renxuan sighed and looked at Gu Beichuan's eyes, full of brilliance.

"Sometimes, I really want to dig out your brain to see what is in it that makes you think like this."

"It's amazing, it's really amazing!"

When Gu Beichuan heard this, he immediately rolled his eyes.

Dig your head? I'm still slicing experiments, do you think it's still the future?

"Tell me, tell me this, what do you want?"

Emperor Renxuan is an extremely intelligent person, or in other words, if he is not intelligent, he is afraid that it will be difficult to hold the position for thirty years, and he has experienced many ups and downs, but he has never wavered.

These things were all thought up by Gu Beichuan.

If you don't tell him, when you report it to the court, the credit will be his!

But now that I told him, it was equivalent to a piece of the pie.

There is no such good thing in the world, not to mention, Gu Beichuan is still a businessman, and everything pays attention to an equivalent exchange.

Therefore, Emperor Renxuan asserted that Gu Beichuan must have asked for something when he told this.

Sure enough, after Gu Beichuan heard this, he nodded with a smile, talking to a smart person is effortless.

"After all, my brother is the marquis, although I don't often see the current emperor, but compared to a white body like me, the hope is undoubtedly much greater."

"So I hope that my brother can convey it on his behalf, as for the credit, I don't want much, it's just enough for an official position."

Emperor Renxuan smiled when he heard this.
