I saw that on the thin book of Canglan waters, there were three big characters written clearly: Tianyuan County!

What is Amahara-gun?

The meaning of the sky is high, and it is naturally the plain.

The reason why Amahara-gun is called Amahara is because of its flat terrain, but it is surprisingly high.

Hence the name.

If you change Beichuan's words, isn't this a plateau?

It's just that how the map was made is obviously not quite the same as what was taught in geography classes in later generations, so it is not called the plateau, but is called the Tianyuan.

One thing to say, this is almost the county with the lowest population of Daqian.

Why?

Bad!

The conditions here are really poor!

If anyone is sent here to be an official, it is really a very obvious derogatory.

And it's the kind that is relegated to grandma's house, as long as there is no major event in the court to usurp the throne, I probably don't want to go back to Qiandu in this life.

Just find a coffin for yourself in advance, and die of old age in this poor and remote place.

Why are conditions so bad?

Because it's windy! Perennial winds! It's unusual, and it's called a demonic wind!

Under such a strong wind, the soil condition of Tenhara County can be imagined!

Not to mention that it is as fertile as normal land, it is half of it, and it is far from it.

The locals also don't know how to use a variety of vegetation to protect against evil winds.

Only if this is the wrath of God, and send this storm to punish the world.

It is also thanks to the martial arts of today's saints, which are majestic and magnificent.

and has absolute control over the court, so that they dare not chew their tongues.

Otherwise, whether it is an official or a royal history, I am afraid that they will have to criticize Emperor Renxuan, saying that the Son of Heaven is immoral, so that the sky will send a disaster, but it will make the people of Li suffer, which is the emperor's fault!

Whether it was the emperor's fault or not, Gu Beichuan probably didn't care.

He only cares about the soil of Tenhara-gun!

With the topography of Tianyuan County, under the perennial blowing of such a demonic wind, the soil is afraid to be sandy!

It's just that what does this have to do with the floods?

Why did you make Gu Beichuan so excited?

Just because this Tianyuan County also belongs to the Canglan River Basin!

It's just that, in comparison, it is slightly upstream, and the relatively rich Canglan County is slightly downstream, but the two are not far apart.

With the speculation that the soil of Tianyuan County might be sandy, Gu Beichuan became bold and began to speculate about the cause of the flood.

Since the soil of Tianyuan County is sandy, it will naturally take advantage of the situation when it is blown by the demonic wind.

When it reaches the surface of the Canglan River, when it encounters water vapor, it has to condense into a lump and fall into it.

Over time, will the sediment in this river increase day by day?

Will the water level of the riverbed also rise?

Gu Beichuan thought about it, and suddenly remembered that in the local chronicles of Canglan County, it seemed to record the turbulent and turbid river in this flood, as if it had fallen from the sky, like a punishment from heaven, which made people fearful, did not dare to resist, and only blindly ran away.

This corroborates each other with his guess!

Thinking of this, Gu Beichuan gave up the Canglan Water Book and found the thick pile of local chronicles.

I began to rummage, and finally found the original local chronicles of Tenhara and Canglan counties, and began to study them carefully.

After a few hours, Gu Beichuan, who was getting more and more sleepy, raised his head, but his eyes were full of light!

He found it!

In the local chronicles of Tianyuan County, there is indeed a record of wind-blown desertification of the local soil, saying that it has a coarse and hard texture, is fine and micro-particle, and when the demon wind arrives, it can be said that it is flying all over the sky and drilling straight into the nose of the mouth.

So much so that whenever the people of Tianyuan County go out, they need to cover their faces with tulle to prevent wind and sand.

Gu Beichuan was completely excited, isn't this characteristic just wind and sand?

Now that the fact that the soil in Tianyuan County has been blown into sand, the next step is to verify whether there is a heavenly river in Canglan County!

Sure enough, a moment later, Gu Beichuan found a more detailed relevant record in the local chronicles of Canglan County.

It was said that although the soil in the area of Canglan County is fertile, the area near the Canglan River is extremely fertile.

But even so, over the years, no one has grown crops in the area near the Canglan River.

The reason is that once the flood occurs, the levee will burst.

The turbid yellow river water poured down from the sky, making it impossible to avoid it.

If crops are planted in the area near the Canglan River, regardless of people, the crops will surely die.

Such a record undoubtedly verified Gu Beichuan's guess about the Heavenly River.

If so, he will have a score in his heart!

If it was another flood, he might not be able to deal with it, but if it was a river in the sky, it would really be a collision!

It's really heaven that won't die, I Gu Beichuan!

Why is the Heavenly River so easy to govern?

In fact, it is not easy to govern, but it is more cumbersome and requires more lengthy time to operate.

It's just that Gu Beichuan already has everything in his heart for the corresponding process.

Why?

Because he's been there!

Not only him, but I am afraid that most of the people in the Chinese territory in the future generations have experienced it!

What is the resemblance of this so-called Heavenly River to the Yellow River, the mother river of China?

Soil erosion on the Loess Plateau in the middle and upper reaches of the Yellow River is severe, bringing sediment to the lower reaches of the river, so much so that the heavenly river is formed!

Even in later generations, when science and education were already very developed, such a river problem was quite thorny.

In the meteorological news, the Yellow River is a frequent visitor, and has even appeared in junior high school geography books!

As a result, the broad masses of the people have some opinions on how to harness the Yellow River.

Even if you can't say it again, you still know the six-character mantra of returning farmland to forests and grasslands.

And how similar is the situation of this heavenly river to the heavenly river of the Yellow River in later generations?

It's just that the Loess Plateau is vast, and soil erosion is more serious.

More sediment is brought down, and the phenomenon of rivers in the sky is more serious.

So much so that later, it affected several southern provinces.

And the phenomenon of the Canglan River in the sky is a bit stretched.

After all, Tianyuan County is only a county, and there are not as many places of soil erosion as there are on the Loess Plateau.

Therefore, the impact is relatively small, even in the flood season when heavy rains occur, it only caused floods in one county of Canglan County.

As for the other surrounding counties, at best they were slightly affected, and they could not be called disasters.

Of course, the impact is not great now.

But things like soil erosion will get worse and worse over time.

Gu Beichuan had never studied meteorology, so he didn't know where the demon wind in Tianyuan County came from.

He only knew that if he allowed this demonic wind to blow and sand the land of Tianyuan County.

In the past, the terrible disaster of the Yellow River in the sky and the river in the future generations is afraid that it will be repeated in Daqian!

Thinking of this, even if he was sleepy, Gu Beichuan couldn't help but break out in a cold sweat.
