The province of Andong was located on the eastern border of the kingdom of Bactria and Kyoto in the northwest.

Therefore, even if the convoy is driving on the highway, it is difficult to reach the destination in a short time.

According to the management's rough estimates, it will take about two days to get to Kyoto.

Along the way, Zhang Yu was closing his eyes to recuperate, and Zuo Enlin Lang and the four of them had rested enough, so they got together to play cards.

Around noon the next day, a high wall appeared in Zhang Yu's line of sight.

That wall was just too high.

In my impression, only the city walls of Wuguan can be compared.

However, it is only comparable to the height, and the width of the Wuguan city wall is even far less than this wall.

As far as the eye can see, the massive wall stretches across the plain.

This is not a mountainous area, the line of sight is excellent, Zhang Yu is a five-grade evolutionary, and his eyesight is many times better than ordinary people.

But even then, it is impossible to see where the end of the wall is.

"What the hell is that?"

Zoen looked up inadvertently and noticed it too.

Dropping the cards, several people looked out the window, it was too shocking!

"If I'm not mistaken, this wall is the dividing line between the internal and outer realms of Great Xia."

Lin Lang looked out the window and popularized science to a few people, "I have seen the introduction of this wall in the information. It is said that after the outbreak of the virus that year, the Great Xia Kingdom built two important defense lines. ”

"The first line of defense is bounded by Yinping Mountain, with Wuguan, Diguan and Tianguan as important fortresses."

"The second line of defense, this is the wall!"

Kar Weng said: "That's not right, the territory of the Great Xia Kingdom is vast, and the cost of building such a wall is inevitably too huge. Aside from the cost, it is probably also a problem to collect the materials needed to cast the city wall! ”

Lin Lang shrugged his shoulders and said, "You're right, of course the Great Xia Kingdom is not stupid to this extent. It is simply unrealistic to build a wall of this magnitude in such a large country. ”

"So, they only built part of it."

Zhang Yu's heart moved, and said, "Tell me carefully!" ”

"Okay, Brother Yu."

Lin Lang cleared his throat and continued, "This second line of defense, in fact, is the same as the first line of defense, with the help of natural hazards. ”

"For example, Yinping Mountain, as well as mountain passes such as Wuguan and Tianguan, can all be called natural hazards. It's just that this second line of defense is not with the help of mountains, but by water! ”

"If I'm not mistaken, parallel to this wall is a great river with a strong current, called Ba Shui!"

"The water flows from north to south, and the water potential is very complex, and the waves are rolling on the surface, and the water is turbulent. Inside, there are countless whirlpools, not to mention people, even a smaller boat, which dare not cross the river without permission! ”

"The Great Xia Kingdom is in the upper reaches of Bashui, on this undefendable plain, and has built such a huge wall. Further north, where the wall meets Huo Taishan, there is a pass called Jianmen, which should be the way we are going to go. ”

After listening to Lin Lang's introduction, several people couldn't help but be amazed.

To put it that way, the Great Xia Kingdom was actually divided into two halves.

A Bashui River, a Huotai Mountain, and such a wall in the middle divide the territory of the Great Xia Kingdom into two major parts.

Zhang Yu is very curious, how is the connection between the inner and outer regions usually becoming? With just one sword gate, it's too reluctant.

And because of this wall, it looks as if the inner and outer regions are divided.

At the high speed of the convoy, the wall got closer and closer.

About an hour later, the crowd walked under the wall.

I don't know if I don't see it, and I'm shocked when I see it.

This wall is 50 meters high, as majestic as a mountain, and I am afraid that it is even more majestic than the city wall of Zhiwuguan.

On the wall, perhaps because of the proximity to the Sword Gate, the guards of the army can be seen guarding almost everywhere.

In the notches in the city walls, powerful cannons were erected, and the black muzzles of the guns were facing east, as if they were always on guard against the enemy.

When the convoy arrived, the speed slowed down significantly.

Ten minutes later, the convoy was stopped by the defenders.

"Get out of the car and get checked!"

Under the orders of the officer, even a nobleman like Bi Yuntao had to clamp his tail and behave.

Don't try to reason with the army, this is the general rule of the Great Xia National Railway!

In the army, there are many masters.

Maybe a six-rank can run rampant in the province, but in the army, he can cure at least dozens of people!

If there is an emergency war, a military powerhouse like Jianmen may have a Nine Rank Evolver in charge!

Soon, many gladiators, as well as the person in charge of the gladiatorial arena in Andong Province, were inspected.

Get on the bus again and head towards Kyoto.

Bi Yuntao took the two old men and sat in the same car with Zhang Yu.

The originally relaxed environment suddenly became a little crowded.

"After this wall, you'll be in the Inner Realm."

Bi Yuntao sighed like this, he looked at this wall, and there was obviously a special color in his eyes.

Zhang Yu's heart moved, and he asked, "What, what is the difference between the inner and outer regions?" ”

"Of course there is a difference."

Bi Yuntao lit a cigarette, his expression was a little melancholy.

Zhang Yu took the cigarette from his hand, scattered it for everyone, and returned the empty bag to Bi Yuntao.

"Tell me about it." Zhang Yu swallowed the clouds and spit out the fog, looking very curious.

Bi Yuntao glanced at him and said, "Anton Gladiatorial Arena, you are still the first person who dares to be so presumptuous with me. ”

"However, I don't want to be angry with you, after all, I still have to rely on you to help me fight."

"And how many inkblots do you have? Say it! Zhang Yu urged.

The two old men raised their eyes and glanced at Zhang Yu, the beard on the corner of their mouth moved, but they still didn't say anything in the end.

Bi Yuntao smiled indifferently and said, "You may not know that in the Great Xia Kingdom, citizens are divided into four levels. ”

"These fourth-class citizens are gladiators who joined the nationality of the Great Xia Kingdom in the Eastern Great Wilderness, as well as farmers."

"Third-class citizens are the low-level officers of the local superintendents and military divisions, and the merchants and wealthy people of the foreign lands."

"Second-class citizens, are nobles, high-ranking military officers, etc. in foreign lands."

"The existence of these three levels is all citizens of the outer realm, and only when they enter the inner realm can they be regarded as first-class citizens!"

Zhang Yu asked again: "Only aristocratic officers are second-class?" What the hell does that class of citizens do? ”

Bi Yuntao looked at Zhang Yu, and suddenly a sentence protruded from his mouth: "First-class citizens, all of them are the descendants of the promoters of mutant vaccines and the developers!" ”

A sentence, like a thunderbolt on a sunny day, exploded directly in Zhang Yu's heart.

With a hula, Zhang Yu stood up directly.

In the carriage, Zuo Enlin Lang and the four people also followed, and Huo Ran stood up.

The two old men beside Bi Yuntao stood in front of Bi Yuntao without moving.

In the carriage, it was instantly full of ** smell!
