Wushan is a dangerous peak, and after Wushan, it is a plain.

In front of him is an endless grassland, on the grassland, cattle and sheep are living freely. Although it is unsettled, it is a natural pasture during the winter months. The temperature is relatively pleasant, the soil is fertile, and there is no possibility of farming. It's a nomadic paradise. As a herder, no one knows about secretly eating meat, not to mention transporting animals, especially horses, to the Valoran continent to make enough profits.

Wushankou is only two hundred miles away from Thunderbolt City, and the river should be able to hit Thunderbolt City, right? Under the impact of many years, how could Thunderbolt City exist? Are the ancestors of Raiden City stupid?

The solution is very simple, just make a strong wall. Just as the ancient Chinese did when they managed the Yellow River, building higher embankments on both sides of the riverbed would protect the town from threats. It is like the phenomenon of "above-ground river" in the lower reaches of the Yellow River. It is worth mentioning that this is also the reason why the walls on the west side of Raiden City are three times thicker than those on the east side.

Although Wushan is only 200 miles away from Raiden City, the east side of Raiden City is still a plain with a flat river. The coastal mudflats further east of Raiden City have become the best way to solve the food problem in Raiden City.

However, Wang Xiaoshuai also observed another strange phenomenon, extremely strange - the downstream alluvial fan of Wushan did not have a very clear riverbed, or rather, there was a riverbed everywhere. One after another, but the problem is that they don't have much intention of coming together at all, and they flow in all directions!

It's just so weird!

is still the same sentence, the layman looks at the excitement, and the insider looks at the doorway. Wang Xiaoshuai, who has learned half-baked geography knowledge, is still able to skillfully describe the process of river formation. This is an extremely important knowledge point in the compulsory course of geography in high school. Regarding the traceable erosion and V-shaped valley in the upper reaches of the river, the trough valley in the middle reaches of the river, a river must play an indispensable external role in shaping the terrain in the process of formation.

However, the strangest thing is that there is a V-shaped valley in Wushan, but there is no large trough valley outside Wushan! What does this mean? Wang Xiaoshuai didn't know, he just felt very strange.

What Wang Xiaoshuai knows is that the rate of traceable erosion is much faster than the rate at which U-shaped valleys are formed.

The most likely explanation is that the river came down from heaven. It is a river that falls from the sky.

Because he didn't dare to ride a horse quickly, Wang Xiaoshuai had more time to fully observe the world. Not long after Li Shen and Li Li left, Master Yi seemed to sense something, and Sun Wukong and Zhou Zheng also followed him and galloped towards Thunderbolt City.

Zhao Rusi rode a white horse and walked a little ahead.

The blue sky and white clouds, the huge grassland is endless, and after a short distance, you can see rows of cattle and sheep, and birds chirping in the sky.

A short walk to the east, you will see a huge city wall. That city wall has provided protection for the people of the capital of Shu for hundreds of years.

The speed of Zhao Rusi's mount slowed down, and she and Wang Xiaoshuai rode side by side, without speaking, and just quietly let the horse go forward. Wang Xiaoshuai looked at Zhao Rusi, she was still wearing the clothes she saw for the first time that day.

The silver-white long skirt looks like a Xiguo style. A small white flower blooming on the back is sewn on the back, which is also the standard design of the aristocratic women of the Xi Kingdom. A white rose on the left symbolizes the great motherland; A daffodil on the right symbolizes the Zhao family of Xiguo. However, instead of a close-up of two flowers, two flowers containing two parts of the neck (homophone) and the flower, the necks of the flowers are crossed together like two swords. In fact, the coat of arms on the backs of the noble men of the Xi Kingdom is also interlaced with two swords, one of which symbolizes the imperial power of the Xi Kingdom and the other symbolizes the power of the clan, but this will be left for more detail later.

Although the architectural style of Xiguo is more baroque, the long skirt on Zhao Rusi's body is different from the material of medieval European aristocratic ladies or Hanfu, but more like Mongolian robes.

Its greatest feature is its flexibility.

When turned over on the horse, this well-tailored skirt will neither hinder movement due to the stiff structure nor trip over itself due to the excessively long skirt. Of course, because it is tailor-made, there are generally no embarrassing situations, and the activity can be carried out with confidence - therefore, the tailor does not have much energy to pay attention to the beauty of movement and decoration at the same time. This kind of simple and simple, single texture, and a lot of white space is the favorite of women in Xiguo, especially Zhao Rusi.

However, the horse didn't look like it matched the outfit well, and it was limping. It's okay to look at, but Wang Xiaoshuai estimates that if they want to run away, this horse may have problems. Seeing Wang Xiaoshuai's gathered gaze, Zhao Rusi smiled gently.

"You like this horse too?" She stroked the horse's head.

"Hmm. Well. Wang Xiaoshuai didn't know what to say, so he could only reply hesitantly.

As soon as Zhao Rusi heard this, he glanced at him and stopped talking.

[It seems that he doesn't like it.] She heard it.

"His name is Wings." Zhao Rusi introduced in a soft tone. Only Wang Xiaoshuai and Qiu Yi could hear her voice.

"This horse is pretty good-looking." Wang Xiaoshuai said with a smile.

"But I think it must have a leg injury on its hind leg, right? At the knee level, it seems that it is difficult to maintain balance. I think this horse can have problems when it runs, and it's not good if you fall. Wang Xiaoshuai touched his nose.

The horse snorted loudly. And Zhao Rusi also smiled.

"No, I always feel like this horse can fly me one day!" Zhao Rusi had little stars in her eyes.

"Okay."

Now that Zhao Rusi has made up his mind, Wang Xiaoshuai has no choice. Anyway, they shouldn't have a chance to go on a rampage, right?

However, talking to Zhao Rusi, Wang Xiaoshuai also wanted to ride a horse quickly.

"Want to try to ride a horse faster?" Wang Xiaoshuai asked.

Seeing Zhao Rusi nodding, he gently clamped the stirrup and rode forward.

Strange to say, the technique of cycling seemed to be imprinted in his head.

As a person in modern society, Wang Xiaoshuai did not have the opportunity to learn to ride a horse. However, from the moment he crossed over, he knew that he could ride a horse as if he could ride a bicycle.

Zhao Rusi fell behind slightly, and she saw Wang Xiaoshuai looking back at her.

At that time, he also rode horses like this.

Zhao Rusi smiled knowingly
