The two of them could not open their eyes because of the strong light. They instinctively raised their hands to cover them in front of them, but to no avail.

Fortunately, after a moment, the bright green light darkened by itself. The gunsmith and John opened their eyes almost at the same time and saw incredible changes.

The environment they were in has changed. The originally square metal room has now become cylindrical. The only difference between the same black walls, murals and texts that emit light is the shape of the room.

"What did you do just now?" John asked.

The gunsmith replied: "I found a symbol that looks like a handprint, so I tried to press my palm on it, and then the light behind the symbol became brighter and brighter..."

John said: "Is that a switch that can change the shape of a room?"

The gunsmith said, "No... the room has not changed, but the creatures in the room have been moved... I guess this is the secret of moving again after we fell to the bottom of the river." He said, then observed the surroundings and then walked towards a place against the wall.

"Look, this cylindrical room also has such a handprint symbol." The gunsmith half-squatted down and looked at the symbol, "It's smaller than the palm of an adult, and looks like a child..." He paused, "What did this remind you of?"

John's expression changed slightly: "That black humanoid creature?"

"Yes, and look at this height, which is about the same height as the creature's reach when standing. If we want to touch it, we have to bend down." said the gunsmith.

"So?" John looked at the gunsmith, hoping that the other party could give an answer.

The gunsmith said, "Even if you look at me sincerely, I can't give you a definite explanation. I can only speculate... Maybe the Olmekwen you mentioned is clearly related to aliens? Or maybe this civilization that has been more than 1,000 BC is actually far more developed than what we modern people speculate. They did not perish. Instead, they hid in the underground world after encountering some major disaster or accident. The black creatures we see may be one of the survivors."

John listened to this, his expression several times, and finally he could only reply: "It seems that your success in competing for the Nobel Prize in writing a paper may be greater..."

The gunsmith said: "I just guess it casually, but based on the situation where the black creature secretly followed us, my speculation should be relatively reliable. The plane I was riding on and the death of your expedition team were ultimately caused by some unknown magnetic field interference, and most of the time it was caused by this ruins.

God knows when the black creature I saw in the afternoon followed us. Maybe it was following you and your teammates before they were caught by cannibals; or maybe he crawled out of the spire of the ruins I destroyed; maybe there was more than one of these creatures...

The only thing that is certain is that the beginning of activities of these ruins was something that happened in the near future. Unfortunately, we happened to be caught up with. Now, the creatures in this ruins do not want us to leave the rainforest above us for some purpose, and it may even...it wants to attract us to this underground world."

John thought for a while and said, "Suppose the conclusions you analyzed are true. There is a prehistoric high-level creature here that went to sleep thousands of years ago and only woke up recently. If I were them, before returning to the ground, I would first catch a few specimens to study the current level of human civilization and evolution on the earth, and then make a decision."

"It makes sense, and you and I look more research-worthy than the natives wearing grass leaves and eating human flesh." The gunsmith had moved to the other side of the room at this time: "There are also handprint symbols here. There are three such marks in the whole room. I guess according to different mechanisms, they will be transmitted to different rooms."

John suddenly felt spirited: "That is, we have a chance to go out?!"

The gunsmith said: "But the problem now is that we can't understand the text in the room and don't know which mark to press, where it will lead. After completing the transfer, we can only rely on the shape of the room to determine whether we have been here before. If there are thousands of rooms here and many of the shapes are repeated, we may never be able to leave."

The two fell into silence and could not think of a good countermeasure for a moment. In fact, they also understood that this was a waste of time. The final countermeasure was nothing more than constantly pressing the mechanism, hoping to be teleported outside once.

After a while, John spoke again: "Actually, have you noticed that these rooms have no functions at all. Apart from the murals and texts, they are empty. Only the museum will be built like this, but what is the significance of different shapes?"

The gunsmith sighed: "Maybe this kind of civilization has exceeded our understanding too much. It's like if you ask the natives in the jungle to take the elevator. When he went in, he would only wonder about the function of this big iron box. After the elevator stopped on another floor and opened the door, the change in the environment in front of him also became a mystery to him. Haha... it's really similar to what we are facing now."

John stood up and walked to one of the switches: "No matter what, I will sit and wait for death to live for only two days at most. Just think that I am an native who has entered the elevator. Press all dozens of keys and will sooner or later open the elevator door." He said, pressing it on the handprint symbol.

The green light lit up again, swallowing two people. After nearly ten seconds, the surrounding area returned to normal brightness.

This time the room was zigzag, like a winding corridor, where the gunsmith and John were in the middle, and they searched again. The room was as empty as there were only murals and texts, and there were as many handprint symbols this time.

The gunsmith said: "A strange technique. As long as one person presses the switch, the creatures in the room will be sent to another space, and our clothes and items will also move... By the way! Do you want to try it? We press the handprint symbols in two different places at the same time to see what the result will be?"

John wiped the cold sweat from his forehead: "I suddenly thought of the fly-beating man..."

The gunsmith said, "Well...she pretended I didn't say it."

After that, John took over the work of pressing the handprints with all his power. I don’t know what the principle of moving between these rooms is. Anyway, they have never encountered rooms of the same shape, so they have never returned to the previous room. Every time they press the handprint symbol, they will be sent to a new place.

In this way, the gun craftsman counted silently in his heart, and transferred a total of twenty-nine rooms. The time may have passed a few hours, or only half an hour. They have no watch on them and cannot see the sun. It was dusk when they fell into the river, and it may be late at night or early morning. In short, the two of them have completely lost their feelings about time.

At first, whenever they arrived at a room, they would search every handprint symbol on the wall, but then it was fine. There were no rules for the number of these symbols. There were three at least, and nine at most. In short, no matter in any case, they were just teleported to places they had never been to before.

The gunsmith was a little strange. Assuming it was late at night, he had not entered the water since noon, and at most he choked a few mouthfuls of river water to fill his stomach. Why did he still feel tired and hungry after so long? After thinking about it, it must be related to this ruins. Even if the temperature, humidity and air quality here are pretty good, people always have to be hungry when they should be hungry. After more than twenty hours, they are always exhausted. And... The gunsmith's expression suddenly became very strange. He suddenly realized that he did not even feel the need to go to the toilet at all, which was strange.

Just as he was about to ask John if this was the case, there was another blue light in front of him. Before he could open his eyes completely, John shouted: "Look! Charles! It's a passage!"

The gunsmith regained his sight and found himself in a straight corridor that led to the distance. At first glance, he could not see the head at all. The murals and text were replaced by two green light tracks, and there were no handprint symbols around it.

John said excitedly: "Do you think this is a way out?"
