Chu Jungui looked at the mist below and jumped down.

In the blink of an eye, he saw through the fog and saw the bottom of the hall. Although the height was only a dozen meters when he saw the ground clearly, the test subject's 23.0 basic combat was not an ornament, and it was instantly adjusted and easily landed on the ground.

The ground is not particularly hard, but a little soft. Chu Jungui squatted down and reached out to touch the ground. The floor of the hall was dark purple with strange patterns, and something was faintly flowing under the purple.

Chu Jungui pulled out the short knife, thought about it and put it away again. If the whole nest is really some giant creature, now is not the time to stimulate it.

He turned on the communication channel and whispered: "It has landed safely, with a height of 131.4 meters, no hostile creatures have been found for the time being, and we are ready to expand the scope of exploration." ”

"Stay safe. Do you need a laser beacon?"

"No, be careful to conceal and not be easily exposed. ”

"Good. ”

Chu Jungui turned off the communication channel, adjusted the personal terminal, and set the sound wave frequency. Every few seconds, the personal terminal emits a ticking sound. Slowly, silhouettes appeared in Chu Jungui's field of vision.

On his left-hand side, there were cylinders, densely packed, and there were more than eight hundred of them. On the right-hand side, there are countless pipes of varying thicknesses. Directly in front, in the center of the hall, there are four high platforms, one large and three small. The largest is 50 meters in diameter and 45 meters in height. The rest of the diameters are around 30 meters in height.

Chu Jungui weighed it and touched it to the left. He bowed slightly, ready to attack at any moment, and then held a knife in his left hand and a mechanical keyboard in his right hand.

In the blink of an eye, cylinders appeared in Chu Jungui's field of vision. These cylinders are dark purple throughout, and the surface material is faintly transparent, like glass, and the material that makes up the gate.

Chu Jungui slowly came to the bottom of a cylinder, and after confirming that there was no enemy hiding, he began to observe carefully. The cylinders are 3 meters in diameter and 10 meters high, and each one is the same size. Its surface is smooth and unified, and there are no openings.

Chu Jungui continuously switched multiple fields of vision, and he couldn't see through the surface of the cylinder. He tapped a few times, and could only tell that it should be liquid inside, and he didn't know what it was.

Underneath the cylinder is a slightly raised body tissue that connects the cylinder to the ground.

Chu Jungui did not immediately destroy the cylinder, but passed through it. Every few minutes, he would send a signal to Lin Xi to show that he was safe.

The electromagnetic field in the underground hall seemed to be extremely violent, and there was already considerable interference after a few hundred meters, and the noise in the communication channel was so loud that it was almost impossible to hear what the other party was saying. Therefore, Chu Jungui could only express his location and safety in the form of text messages.

Passing through the cylindrical forest, on the opposite side of the passage where Chu Jun returned, a straight wall appeared, no longer in an arc shape. The walls are made of the same material similar to glass.

Standing in front of this hundred-meter-high giant wall, Chu Jungui once again felt his insignificance.

The wall does not seem to be a stand-alone existence, it protrudes as if it were a square independent space, embedded in the underground hall.

From the right side of the wall, numerous pipes protrude, ranging from more than 10 meters in diameter to 1 meter in thin. Numerous pipelines run along the walls of the hall, with dozens of cylinders connected in between. It's just that the bottom of these cylinders is embedded in the wall, stretching horizontally, unlike the cylinder forest on the other side, which is connected to the ground.

If the entrance can still make people feel primitive and barbaric, the pipes and cylinders in the hall let there be traces of civilization. No matter how Chu Jungui looked, he felt that those cylinders with the same diameter should be industrial creations. If the organism grows on its own, it is generally impossible to be so standard, there will always be coarse and fine. And those neatly arranged pipes are also very industrial, not very natural.

Chu Jungui sent a message to Lin Xi: "A suspected biochemical factory has been found, there is no sign of the enemy for the time being, continue to explore." ”

The probe showed that there was a liquid flow in the pipeline, the flow direction was not consistent, and the cylinder did not know if it was a transfer station or some other function. The whole pipeline and cylinder constitute a very complex closed circulation system, which is an authentic civilization creation.

The entire underground hall was filled with fog, and it was unknown if it was part of the overall system. Scans of the personal terminals showed that the composition of the air in the lobby was very different from the outside atmosphere, and that there were quite a few microorganisms.

There is almost no oxygen in the air, and there is no need to think about whether you can breathe or not. However, Chu Jungui wanted to know if these microorganisms in the air were harmful.

This problem is actually easy to solve, and the subject takes off his mask and swallows a deep breath of air.

It was swallowing rather than inhaling, and this ball of air was sent into the stomach and began to come into contact with Chu Jungui's flesh and blood. As a result of the encounter between the two sides, all microorganisms were wiped out in an instant.

Subject felt that his digestive system seemed to be a little too unfriendly to microorganisms. So he took off his mask again and took a small puff.

After a while, Chu Jungui concluded that his respiratory system was also not friendly to foreign microorganisms.

Chu Jungui roughly concluded that the microorganisms here were not only harmless, but also quite fragile, and had little resistance to the normal immune system in the human body, let alone the abnormal system of the test subject.

At least Lin Xi and the others are not likely to get sick after aspiration.

After exploring the surroundings, there were only four high platforms left in the center. In fact, there has been no movement for such a long time, and there should not be much danger, but Chu Jungui did not relax his vigilance and slowly approached the high platform.

At this moment, in the distance, in an identical valley, a large, three, small and four black shadows gathered in one place, discussing something.

The three black shadows looked very excited, their eyes flying everywhere, shining brightly, and making all kinds of strange sounds. Moreover, their language organization skills have been greatly degraded, and all kinds of logic are incomprehensible, but the amazing thing is that they understand each other quite well.

The content of the quarrel is roughly how to lose the Beast's Nest Valley.

The three small black shadows are desperately trying to clear their relationship and throw the pot on each other's heads. For example, the mobilization of war beasts is not timely, the combat effectiveness of the mobile base is underestimated, and the mobile base is not expected to suddenly kill the beast's nest, etc.

Although the three groups of black shadows were noisy and the energy rays were shooting everywhere, none of them mentioned the troops attacking the mobile base, in fact, the central black shadows themselves selected.

I don't know how long the quarrel lasted, although the three small black shadows were arguing with themselves, the big black shadow in the center was always silent and didn't say a word. But there were hundreds of eyes floating on the surface of its body, clearly thinking about something.

Suddenly, all the eyes of the central black shadow bloomed at the same time!

The three small black shadows were startled, and at the same time looked at the central black shadow.

The black shadow in the center was silent for a moment, and Fang said, "I forgot to bring my luggage." ”
