Yu Tu and the three left in the opposite direction. After looking for an opportunity to determine a lower position, the three began to move along the outer ring area of ​​the city ruins.

Of the four missions, except for the last one, Bennister is uncertain, the rest are related to the undead. Through previous inspections, there are many war puppets in the center of the town. There must be a lot of monsters with four arms.

In other words, the inner area of ​​the city is likely to be the domain of these monsters. The Necromancer, Necromancer, and the like will certainly not be within the patrol range of those puppets.

In other words, Yu Tu did not feel that there were high-level necromantic monsters in this ruin.

This kind of speculation can only be determined through their follow-up observations. At least for now, it looks the same as expected.

Not only that, they also found that the four-armed monsters here and the vampires above are not together. The vampires who had been dispelled by Yu Tu lingered for a while before directly attacking a certain group of war puppets in the city. It didn't take long to drag a few four-armed monsters away.

It seems that the status of vampires here is even higher than that of the dead. This makes Yu Tu feel there is room for use.

Carefully avoiding the four-armed monsters on patrol, Yu Tu and the others found a passage to the underground.

Yu Shuang on one side said: "What is the idea of ​​these ancient countries? It is nothing more than the underground cities built on the ground. This underground city also has underground. Is it the custom of the time?"

While checking the entrance to the crypt, Yu Tu explained: "The current ruins are basically leftovers from the kingdom period. There is an era before the kingdom period. It is more chaotic than the kingdom period. The kingdom basically depends on that era. It’s not that the kingdoms built the dungeons, but that the kingdoms built their own cities on the basis of the dungeons. Of course, there are also some kingdoms that have risen by themselves. The relics of this type of kingdom are difficult to preserve ."

Yu Shuang shrugged and asked, "Then, shall we go down? I don't think our goal will be here. We may have found the wrong position."

"I think so. However, I am more curious about this ruin. Anyway, there is no time limit for the mission. How about going down to see? There is no sign of passing, at least this entrance has not been used for a long time."

Yu Mu looked at the gap when they came. They were only less than one meter high, and those tall four-armed monsters couldn't get in at all. This also means that they don't have to worry about being blocked by a group of monsters when they return.

Yu Tu took out the magic lamp and took the lead into the passage.

The passage did not feel dull. A layer of gray sand accumulated on the ground. After confirmation, Ivan said that those were ashes. The whole passage was covered with this kind of ashes, but they couldn't guess what it represented.

After Yu Tu counted the 133 steps, they walked out of the passage. With a setting of 30 cm in the first step, this underground area is more than 40 meters above the ground. This height is a bit exaggerated. At least Yu Tu can't imagine how many load-bearing buildings are needed to support the city above.

When they completely walked out of the passage, Yu Shuang's mouth grew wide, Yu Mu narrowed his eyes, and Yu Tu took a small step back in surprise.

Their location is a platform, not big, connected to the plank road close to the wall. Looking up, you can see a zenith carved with battles between gods and monsters, with a large number of bright gems inlaid on it, and the gems on the wall illuminate the entire space.

This is a closed underground city. The height from the ground to the zenith is visually two hundred meters. Yu Tu opened the map and determined the size of this space.

The ruins above him are a standard square. And this space is the largest circle in the square.

The only visible load-bearing column is located at the center of the circle and directly leads to the zenith above. There are a lot of holes on it. It is estimated to be some kind of tower-like building.

What shocked the three of them most was not the huge space, but the bustling town below.

There is no feeling of run-down in the brightly lit bustling city. Except, there are no residents.

Yu Tu said: "I was wrong in what I just said. The ruins above are not a kingdom city built on a ruin, but a defensive city built on itself. I have never seen such a ruin. Record."

Yu Shuang blinked and asked, "So, is it safe below?"

"There is no gain in the perception of blood energy. There is no gain in the perception of soul. It may be an empty city. Yu Mu, have you found out?"

Yu Mu nodded, raised his finger to the zenith above.

"The picture carved above, I have it in my data."

Yu Tu raised his head and looked at the pattern on it carefully. I just glanced briefly, and I haven't read the specific content carefully.

The pattern depicts a lot of things, very complicated. But the theme is very obvious, it is fighting. Fighting between various monsters, fighting between various races. But these battle scenes are all constrained in a range like a snake body. No, just like a snake. These depictions are as if they were carved on the body of a huge snake.

After having the direction, Yu Tu saw more things when looking at the zenith again. Looking at the zenith formed by two snakes coiling together, there is actually only one snake. Both ends are in the center of the zenith. I can't see the exact appearance, but Yu Tu still has a guess.

"Is this the pattern painted on the body-eaten snake?"

Yu Mu nodded and said, "Yes, the basis of this picture is the snake of the body. The name of this picture is the snake of doom."

"What do you mean?"

"In the era when there was no country with only races, there was a war that could be called extinction. Basically all races were involved, and the powerful beings do not know how much they fell. And this picture describes the last one. A war. It’s said that during that battle, a snake that swallowed the body suddenly appeared on the battlefield and swallowed tens of millions of strong men on the battlefield. In the end, it was swallowed together with the battlefield and myself.

Yu Shuang asked in surprise: "Does this really exist? It sounds too unreliable. I don't think Qingyu has such a powerful force."

Qingyu raised her head, took a look, and then continued to fall. It really can't. But it does not mean that this matter is false.

Yu Mu said calmly: "The only record left of that incident is the doomsday snake on the top of the sky. This was left by some of the survivors who became fanatics. Kingdom Period There are many copies of this painting. It’s just that by the time I was in, I didn’t know why it was about to disappear completely. This place should be a country before the kingdom period."
