After the camera adjusted to the light, Chen Xu finally saw the scene outside the door. There were four people standing outside. They were wearing black armor and helmets, and holding weapons similar to broadswords in their hands. Facing the clones, they all seemed very respectful, half-hiding their bodies, and performing a strange etiquette.

The clone walked out without saying a word.

Outside was a huge square with strange patterns carved on the ground, covering the entire square.

Not far away, there are several huge round pillars, which seem to be the support of the underground world.

There were lights on the pillars, and the dazzling light was coming from there. It was also because the lights were too bright that I couldn't see how high the pillars were, and there was darkness above them.

Due to the presence of the four people behind him, the clone did not look closely and walked straight forward.

The square was very large, and apart from those four people, no other figures could be seen.

He walked out of the range of the light and soon came to a wall. In the darkness, he could vaguely see several passages in it.

The clone walked towards the nearest passage, and after passing through it, he came to another huge square. Unlike the previous one, there were a lot of people here. Tall houses could be seen at first sight.

There were two people guarding the exit of the passage. When they saw him come out, they bowed but did not say a word or stop him.

"Underground world?"

Chen Xu had already guessed it just now, and looked around curiously at this underground human habitation area.

In this square, there is a huge round pillar at a certain distance. On each pillar is a round lamp, which is very large and emits golden light, and can illuminate very far. It is also the light source of the square.

"Strange, why is this place built so high? If it is divided into several floors, it can accommodate more people." Chen Xu was somewhat puzzled as he observed.

Although it is called a square, it is actually very large. At least from the video, it seems as if there is no end in sight.

After crossing an open space, the clone finally walked into a street. Some pedestrians, both men and women, could be seen on the road, wearing very exotic clothes. When these people saw the clone, they automatically gave way to the side of the road.

"Are there any obvious characteristics on him?" Chen Xu was a little curious. Whether it was the four people at the beginning, the guards guarding the passage, or even the pedestrians on the street, they were all very respectful to the clone. There must be a reason for this.

"Is it the clothes he's wearing?"

Chen Xu guessed this because there were no other features on the clone that could be quickly identified.

In addition to pedestrians, he also noticed the buildings on both sides of the street. How should I put it? It felt a bit out of place. From the perspective of style, it could be called exquisite, but it did not have the industrial beauty of modern buildings.

This is interesting.

He explored this underground world following the footsteps of the clone as if he was watching a movie.

The clone did not stop for long, and walked through the area from the main road, and walked to the end, where there was another passage. There were also guards outside the passage, and when they saw him, they did not stop him either.

After passing through the passage, there is another huge space...

The entire underground world seems to be composed of such a huge space.

The clone seemed to realize that the clothes he was wearing were too eye-catching, so he took them off and put on other clothes while passing through a passage.

Taking into account that the clones couldn't speak the language, a package was prepared this time, which included some food and water in addition to the clothes.

After changing clothes, although the style was somewhat out of tune with the locals, it was not as noticeable as before.

Chen Xu didn't observe too many details. Except for the beginning, he fast-forwarded the rest.

It was not until half a month later that the clone passed through the passage again and finally saw a different scene. There was no dazzling light and no huge round pillar.

This is a much smaller space. The only light source is a lamp in the middle, which emits a white light. The light becomes very dim from a distance.

Chen Xu's first impression was that it was dirty and messy. Both the people on the street and the buildings were very different from the previous spaces, just like the difference between a slum and a rich area.

The further you go out, the worse the conditions become.

Finally, the clone passed through a heavily guarded passage and came to an uninhabited space.

"Is it an abandoned residence or a natural underground cave?" Chen Xu was a little surprised that there was such a place in the underground world.

The clone lit a torch, and wherever the fire shone, plants grew everywhere. He stayed here for a while and then went back through the passage.

Then, the clones began to walk back, their food and water supplies running low.

Feng Song dissected the original bodies of the clones. Their body structures are quite different from humans, which is reflected in their higher utilization rate of food energy, which means they are more resistant to hunger and thirst.

They only need one meal and a small amount of water a day, and are much easier to feed than humans.

Even so, the food and water he brought could only last for a month at most. His order was to report back what he saw and heard, and he faithfully did his job.

When the clone was walking back, things were not so smooth, especially when he wanted to enter the "rich area", he was stopped and not allowed to pass.

He could only change into his original clothes and go through another passage. This time, everything went smoothly.

The clothes he was wearing were obviously a symbol of his status. Chen Xu guessed that this clothes represented that he had a parasitic armor.

If his guess is correct, it also means that the warriors who can wear parasitic armor are a minority of elites in the underground world.

The clone walked back faster and everything went smoothly until it was stopped when it was about to enter the square at the beginning.

The clone naturally couldn't understand what the two guards were saying. At this point, he could only force his way in.

The clone's physique was extremely strong. In terms of physical fitness, even Chen Xu was far from being able to compare with him. In a close-range sneak attack, he instantly killed the two guards and rushed into the passage.

After arriving at the square, I saw the four people again.

After a fierce battle, the clone won, but he was also seriously injured. When he took the elevator up, he saw the reinforcements of the underground people just rushing in.

After reaching the passage on the ground, the clone ran out of the cave. After a while, he heard footsteps behind him. The underground people actually caught up with him.

In the end, he didn't even have time to put on his protective suit, he just opened the door and ran all the way out of the cave, and fell down when he ran out of the cave.

When the video fell into darkness, Chen Xu felt a little complicated. Although it was a clone, the spirit and will to complete the mission at the cost of death touched him.

He took off his glasses and soon calmed down, thinking about what he saw in the video.

The information brought back by the clone this time was very valuable. At least it let him know that there was a group of humans living underground.

Although it was just a cursory viewing, Chen Xu could roughly judge the technological level of the underground people just from the content of the video. At least he didn't have to worry about the other party bringing out a large army to destroy him with artillery fire.

And parasitic armor was not seen either, so it should be a very rare type of soldier.

However, he did not take it lightly. A civilization that could create such an underground world must have a high level of technology. Even a rotten ship has its nails. The underground people may have inherited some of the legacy, so it is not surprising that they have some powerful weapons.

Chen Xu decided to continue to strengthen his war preparations. This time the clones broke through the barrier, and he didn't know if it would cause other changes.

The specific arrangements would have to wait until the information in the video was analyzed. He fast-forwarded through the video and skipped most of the content.

It’s better to leave such delicate things to cyborgs, as they have better patience.
