Zhang Jun didn't know why the door of the bunker suddenly opened a few days ago, but he guessed that it had something to do with the shaking of the bunker, because the gate of the bunker suddenly opened after the volcanic eruption, maybe the earthquake caused it to open suddenly, and the door was slammed open by the Big Mac hitting the wall hard, so maybe this is why they opened, but the specific reason for this, Zhang Jun still couldn't figure it out, he had to stay and slowly explore the mystery.

There are so many spaces in this bunker, Zhang Jun knows that they must still contain a lot of secrets, and he needs to figure them out one by one, but he knows that at least the giant centipede family occupies one of the spaces, so it cannot be ruled out that there will also be dangerous creatures in other spaces, so everything needs to be careful.

The sound of fighting outside gradually stopped, and the surrounding corridors and the grass outside were full of giant centipede corpses, Zhang Jun was worried that other Allosaurus would run in and damage the things inside, so he didn't go out, and stayed in the space all the time, studying the various buttons on the table.

Zhang Jun counted the number of spaces in the bunker that were divided by corridors, and found that counting the space he was in, there were as many as sixty-one spaces, the closer to the center, the smaller the space, and the closer to the periphery, the larger the space, because the space here was fan-shaped.

After most of the other Allosaurus were driven out by Zhang Jun, he walked around the corridors with a bald head and black skin, but found nothing, and then returned to the central space alone.

When Zhang Jun returned to the central space again, his eyes suddenly swept to an astonishing fact, that is, the blood stains left by the giant centipede on the ground slowly disappeared, he stared at a ground with his eyes, there was a pool of black blood left by the giant centipede, about a square meter, he stared at the place for a few minutes, and found that the pool of blood slowly seemed to evaporate, gradually disappearing.

Zhang Jun then went outside the door to take a look, and he found that the blood stains left by the giant centipedes everywhere were also slowly disappearing, as if they had been absorbed by the ground, and he was immediately surprised.

"Alien technology is really awesome, can this ground automatically clean up the dirt?" Zhang Jun sighed in his heart, feeling that this place must be magical.

The corpses of the giant centipedes in the bunker had already been eaten by the dragons, and some of the centipede corpses on the ground could not eat the rest, so they were immediately dragged away by the three members of the Flame Barbarian Dragon, and the rest became the delicacy of the Oak Dragon and the Void Bone Dragon.

In the next few days, Zhang Jun stayed alone in the bunker and began to study the equipment in the central space, and then he found that the remaining giant centipede fur and skeleton outside were also absorbed by the ground in a few days, which made him even more amazed, the ground here can melt and absorb all the bones, this kind of magical technology is not seen on the earth, beyond the earth I don't know how many eras.

Zhang Jun couldn't figure out why the ground didn't absorb their bodies directly when the giant centipedes were alive, and thought that maybe the ground here only absorbed dead things, not living things, let alone the items in the bunker, it seems that the scientific and technological level of the bunker is indeed ridiculously high.

Therefore, there was no need for Zhang Jun to clean up the place, and the bunker quickly became very clean, leaving no smell and debris of the bodies of the giant centipedes, as if they had never existed.

On this day, Zhang Jun suddenly thought of something, so he walked down the bunker corridor, and began to look for the part of the space connected to the dirt bag on the ground, and finally he found its approximate location, this reading space is located two hundred meters away from the central space, it is a large space, located on the edge of the bunker.

That space was also closed, so Zhang Jun didn't know what was inside, and it was unknown what kind of energy made this space capable of producing such a swift tornado.

In the past few days, Zhang Jun can feel that this space will tremble at that moment, and then there will be a tornado on the ground, and then he carefully felt the changes in the bunker after the tornado, and he found something again, because every time the tornado is generated, the air in the bunker will suddenly become fresher, which is a sensitive surname that Zhang Jun has more than other dinosaurs after a long period of cultivation, and he can distinguish the freshness of the air very clearly.

So Zhang Jun guessed that this space might be a ventilation space, and at this moment every day, it would drive it once a day, pumping out the turbid air in the bunker and replacing it with fresh air on the ground, but how it did it was not yet known.

So far, Zhang Jun has only learned about the three spaces in the bunker, the central space and the space where the giant centipede's lair is located, as well as this enclosed space related to tornadoes, and still knows nothing about the other spaces.

Then Zhang Jun went to the space of the giant centipede's lair, he had long been interested in the purple luminous object on the round platform, and he was busy studying in the central space for the past few days, so he didn't have time to study it.

After Zhang Jun entered that space, he found that the round platform was still inside, but there was nothing on it, and he didn't see any purple luminous objects, he felt a little surprised, so he walked to the round platform, stretched out his paws and touched the surface of the round platform a few times.

At first, the round platform did not react, but after a few seconds, a faint purple light emanated from the surface, which was the light emitted from the center of the round platform, Zhang Jun stretched out his claws and placed them in the light, feeling a mysterious energy that seemed to be shining on his claws.

It didn't take long for Zhang Jun to see a great change on the surface of the round table, and a purple powder slowly overflowed from its surface, as if it had penetrated out, and those powders gathered in the central part, slowly becoming more, but after a few minutes, the purple light suddenly converged, and the powder no longer appeared.

Zhang Jun saw the small piece of powder, only a little the size of his little finger, and immediately stretched out his nose to smell it, and found that it actually had a faint fragrance, which can be smelled by animals with sensitive taste.

"Is this thing edible?" Zhang Jun thought to himself, because he had seen giant centipedes surrounding here before, as if they were rushing to devour this purple powder.

Zhang Jun was wondering how those giant centipedes survived if they were locked up in the bunker space for a long time, and now he guessed that it was probably related to this powder, or maybe they provided energy to allow the giant centipedes to multiply in this small space.

Zhang Jun knew that the giant centipede may be hundreds of millions of years ago, the descendants of some ancient reptile arthropods, they should not have appeared in the Jurassic, it is likely that the bunker space left by this alien has allowed them to successfully escape several mass extinctions, thus extending the race to the present, and they are very large, perhaps this is also related to the bunker space and purple powder.
