Chen Fan couldn't hide his excitement, but he didn't speak, but stared at the black city wall tightly, surprised and surprised in his heart.

The black city wall is like a continuous group of mountains, in the form of a serpentine around the entire isolation area of Yunxi City, the city wall is twenty meters high from the ground, enough to resist more than ninety percent of the primary monsters, and on the city wall, you can see a large number of patrolling soldiers everywhere, a ballista stands on the top of the city wall, on the ballista, like an adult's thigh-thick fine ** arrows are equipped, ready to burst out at any time with amazing power.

Under such equipment, the city defense fortress of Yunxi City can be called impregnable, even if a real third-level monster descends, I am afraid that it will not be able to easily break through this black city wall.

"I didn't expect that in just a few months, they have built such a large city wall, the efficiency is really amazing!" Zhou Tao also looked stunned for a moment, not only sighed.

Before leaving, Zhou Tao was still worried about the fortifications of Yunxi City, but now it seems that even without him in command, with the efficiency of Zhou Xu and Lin Yuan, it is enough to strengthen the entire city.

Today's Yunxi City is indeed a little different from before.

Although the two top combat powers have not been stationed for a long time, they still have three second-level peak combat power abilities, as well as more than two hundred junior abilities.

In particular, this majestic city wall, which has been built by everyone who has worked tirelessly, is not only huge in scale, but also extremely impressive in structure and density, enough to withstand the destruction of any artillery fire, as long as it is not a real nuclear bomb, nothing in the human world can damage it in the slightest.

Chen Fan walked under the black city wall, put his hand on the towering wall, and sensed it with his heart.

It can be determined that these mineral crystals that built the city wall were transported back from the Death Valley, and the mineral crystals of the other world completely replaced the steel of the human world, and their density and hardness were far from being comparable to ordinary steel, at least the monsters below the third level of combat power had no possibility of breaking through this city wall at all.

The majestic winding stone wall like the Great Wall, imposing, at least stretched for nearly a few kilometers, such a vast total amount of work, it was almost unimaginable before the end of the era, even Chen Fan didn't quite understand, he was only away for just three months, why was Yunxi City transformed into this appearance?

With the previous population size of Yunxi City, there was no way to do this kind of thing.

Soon after, a team suddenly walked out of the top of the city wall, someone was looking at this side with a telescope, Chen Fan and Zhou Tao immediately sensed the existence of that person, and they looked up at the top of the city wall, their eyes met, they recognized the person standing on the city wall, it was Zhou Xu, who had not seen him for a few months, Zhou Tao immediately waved his hand and shouted, "Zhou Xu, open the door!" ”

The people on the city wall apparently recognized them as well, and immediately let out an excited cry, and soon after, the gate of the city wall slowly opened, revealing the military isolation area that appeared behind the city wall.

A lot of steel bars and hardened barbed wire were laid in the isolated area, and most of the barbed wire was even electrified, and at least three layers of electrified barbed wire had to be passed through to actually enter the inner city.

With such an arrangement, even if a monster can get away with breaking through the city walls, it will not be able to drive straight into the threat of these power grids.

Chen Fan couldn't help but sigh in his heart, such a city defense, I am afraid that there will not be a second city in the entire Huaguo several times, only in terms of defense capabilities, Yunxi City is definitely the first city in Huaguo.

Soon after passing through the city wall, Zhou Xu had already led a team of more than a dozen people to go down to the building to greet him, Zhou Tao was excited, the two brothers just rushed up and hugged each other, telling each other about the experience after separation, Chen Fan did not leave immediately, but asked Zhou Xu about the origin of the city wall.

Zhou Xu said that not long after Chen Fan and Zhou Tao set off, he directly led the army to the Death Canyon, transported the mineral crystals in the black river back completely, and then rushed to make the city wall day and night, and it only took three months, and the city wall has begun to see scale.

Chen Fan was puzzled, "How can it be possible to build such a large city wall in three months, have you mobilized all the people in the entire city?" ”

Zhou Xu said with a smile, "Not only that, in the entire southwest region, Yunxi City is the only city that can maintain order under the end of the world, so it has attracted a lot of small forces to take refuge, and with more manpower, our power will naturally be even larger, once the force is huge, it can attract more people to take refuge." ”

Chen Fan understood what he meant, Yunxi City has now formed a virtuous circle, and now the development of the city is changing towards a snowball trend, which is simply unstoppable.

Speaking of this, Zhou Xu was extremely excited, and continued to foam at the mouth, "Three months ago, the population of Yunxi City was less than one million, and through continuous absorption, our population has nearly doubled, and two million people participated in the construction of the fortifications of the city wall, of course, the efficiency is fast!" ”

Chen Fan nodded again and again, pursing his lips and laughing with satisfaction, "It seems that my original choice was not wrong, Liu Yunshan is indeed a very capable leader, and the development of Yunxi City has far exceeded my initial expectations." ”

"Of course!" Zhou Xu was happy, his eyes showed a little madness, and he suddenly pointed to the team following the two of them, puzzled,

"By the way, what's going on with these people behind you?"

Zhou Tao said, "Oh, they are the Jin family's troops, I will explain the details to you later, these people will be arranged by you, take them to the military camp to settle down first." ”

"Good!" Zhou Xu immediately agreed, and said to Sun Jun, who was walking in front of the army, "You go to the barracks with me to register first." ”

Since there are so many people who have taken refuge in Yunxi City recently, they must first be inspected here, as well as register the population, and they must first let the high-level officials of Yunxi City accurately grasp all the information before they are qualified to stay in the city.

Managing such a large city is not an easy task, and if you don't have precise control over the information of each refuge, it is likely to cause a lot of chaos.

Sun Jun hurriedly agreed and obediently followed behind Zhou Xu.

Zhou Tao and Chen Fan quickly passed through this quarantine area and returned to the inner circle of the city smoothly.

Walking on the familiar city streets, Zhou Tao couldn't help but sigh, looked around at the busy figures on the road, sighed and said, "This is the Yunxi City I am familiar with, the gathering place of human life should be like this, busy and lively." ”

Due to the existence of that city wall, there are no more strange beasts in the city of Yunxi City, so those who live in the basement can also see the light of day.

Chen Fan nodded, "You're right, the calmer you are, the more you must know how hard it is to protect this peace, as the leader of this city, it is indeed not easy for Liuyun Mountain." ”

Zhou Tao suddenly grinned and said seriously to Chen Fan, "I feel that you don't want to be the same as before." ”

"Is there one?"

Chen Fan was slightly stunned, but soon, he smiled again.

People are always changing, and changes in the environment will also cause changes in people's mentality, in a relatively safe and relaxed environment, Chen Fan naturally does not have to expose his fierce and indifferent side all the time.
