Half a month later, except for the original professional construction workers, other people returned to the territory one after another and went home.

These construction workers will go to the entrance of the mountain to build the pass, and the bridge behind will be built after the pass is completed.

The infantry brigade led by Di Qing has set up camp at the entrance of the mountain pass to prevent unknown enemies. At the same time, he has sent scouts to continue moving forward. The cavalry originally sent out has notified them to return to Tianqi City.

The entrance to the passage where the mountain range is located is just like the mountain described in the reply letter that Zhou Wu showed to Yang Song, with a crack in the middle.

The difference is that this time the cracks are neatly trimmed on both sides, as if a god cut them off with a magic sword!

The source of the earthquake is at the entrance of this mountain range!

Yang Song doesn't look very wide from the small map, but if you zoom in, you will know that this so-called "gap" is still very wide.

The entrance of the passage is about three kilometers long and about one kilometer wide, with cliffs on both sides of the cliff. The sunlight in this gap cannot be seen for more than a few hours a day. This is simply an excellent place to build a pass!

Viewed from the south side of the passage, that is, from the territory's side, the terrain of the entire passage entrance is higher than other places. It is like a high platform inlaid with mountains. You have to pass through a slope formed by a pile of collapsed rocks to enter the passage entrance.

The same goes for the north side of the passage. Going north from the passage, you have to walk through a steeper slope than the south side before you can enter the ordinary ground level.

In this way, we can know that the entire mountain range should have collapsed from the center to the north and south, but it has not completely collapsed to the bottom, and there is still a height of more than 100 meters above the ground that has not collapsed.

But these collapsed rocks were piled up into two slopes on the north and south sides, forming two roads, which facilitated the travel of humans on both sides!

After Yang Song took a closer look at the terrain, he was a little happy in his heart. He didn't expect that this crucial place had not been occupied by humans in this world, but was occupied by him.

But if Yang Song thinks about it more carefully, he is right! He has system prompts, but the humans in the north do not have system prompts, so it is natural that he can occupy this key point.

If it weren't for the system prompt, who would have thought that an earthquake would actually form a passage connecting the north and south sides of the mountain range? He would never believe it no matter what others told him!

The place is now occupied and the roads have been built up to the upper slope of the passage entrance.

The first wall of the pass was built at the junction of the northern passage, and outside the wall is the northern slope!

There is no need to dig deep for the foundation. With the ready-made all-stone foundation, you only need to remove the surface layer of gravel to build a city wall on the mountain.

After this city wall is built, it will be completely integrated with the entire mountain range. Coupled with the thousands of meters long slope, this is an indestructible copper wall and iron wall!

Of course, this is just the plan and design now. Not to mention the iron walls, even the top layer of rubble has not been cleaned yet!

----------

In the camp where the infantry brigade was stationed at the entrance of the mountain pass, in the commander's tent, Lu Su said to Di Qing: "General Di, are you sending more detectives to the north? Follow the passage to keep searching, it is best to find out about human activities.

city!"

"Commander Lu, I have sent out all the light cavalry and scouts of the entire brigade. Even if I send more people, it will not help!" Di Qing comforted Lu Su: "I know you are anxious, why am I not? Now we are the enemy.

I don’t know, I don’t know how to arrange it next!”

There is a reason why Lu Su, who is usually such a steady and calm person, is so impatient now.

Not long after they arrived at the entrance of the passage, the territorial cavalry recalled from the front received news that they had discovered traces of human activity, an abandoned small village.

After Lu Su asked the cavalry to mark the location of the small village on the map, they found that the abandoned village was not far from the mountains, only more than ten kilometers!

This shocked Lu Su. Doesn't this mean that the humans in this world are not far away from them?

So Di Qing immediately sent additional cavalry to conduct inquiries in different directions, trying to obtain more information as soon as possible.

After several days of research, it was discovered that there were several abandoned small villages within more than ten kilometers of the surrounding area. After detailed exploration of these small villages, it was found that these small villages were completely in ruins.

Ren Xian is the captain of the light cavalry brigade. After the light cavalry he led inquired about these abandoned villages, he decided to check it out personally.

He led a small group of light cavalry to the abandoned village on the edge of the passage. Looking at the collapsed houses in front of him, and even the burned-out wreckage, it was so desolate!

Ren Xian dismounted, led his beloved horse into the ruins, and said to his men: "Write down what I said!"

"Yes, Captain!" The deputy next to him also got off his horse, took out the letter from his horse, and got his pen and ink ready.

Ren Xian had no time to pay attention to this. He squatted down, looked carefully at the damaged wooden house in front of him, and said: "The damage time will be within one month."

"Damage time, within one month." The deputy dutifully wrote down everything.

"From the clear traces around it, we can tell that this place was actively abandoned!" Ren Xian continued to analyze.

"There are traces of furniture and tools in the ruins of the house." As he walked around, he suddenly saw a different place in front of him. When he walked over, he saw many traces of wild beast activity and excrement. He said, "This is a place where wild animals have been found."

shed!"

Ren Xian walked out of the village and said to his men: "Clean up these ruins and see if there is anything buried underneath!"

Looking at the messy fields everywhere outside the village, he said: "The humans here have planting and breeding industries! They are civilized humans!"

Ren Xian is right. From these places, we can know that these human beings have already possessed a preliminary civilization, but we don't know what kind of civilization it is.

After a while, the men came to report that they found some fresh corpses from under some collapsed houses!

He hurried over and looked at the two fresh corpses placed in front of him. He squatted down and examined them carefully: "These are two human corpses. They look similar to the savages in the south of the territory, but they are whiter.

And he’s wearing a set of very rough clothes!”

Ren Xian finally came to the conclusion, saying: "The lives of the humans in these villages are not as good as those in the territory, and their technology is not as advanced as those in the territory. The collapse of these houses should have been caused by the earthquake in the past time, and the people here have already

Migrated away."

Ren Xian looked at the direction of the evacuation of the people in this village, holding a riding crop and clasping his hands behind his back. Against the background of the setting sun, his eyes were very deep!

There should be a relatively powerful force over there where these homeless and frightened people can go and receive shelter!

…

Far away in the direction Ren Xian was looking at, a group of ragged refugees were queuing up with their families in tow. Among the refugees who were undergoing inspection when entering the city, a young girl suddenly turned around and looked at her.
