After closing the door of the bunker, Zhang Jun has no interest in continuing to study things related to it, because these high-tech things are not of much significance to the Allosaurus in the Jurassic period, and he only needs to use it as a foothold, a stable nest, it is enough, maybe this is a knife for killing chickens, which is overkill, but at present, there is no other use except for the bunker as a dragon's nest.

As for the creatures inside, as long as the door is closed, it will not come out to make trouble, those spatial doors, no one can open them at all, and now Zhang Jun's information has been recorded by the system in the central space, and he has become the new controller of the space, and he can open and close these doors at will.

However, the bunker control system seems to have a flaw, that is, when it is hit from the outside by excessive force, it will suddenly open the door of the space, which was previously opened by the centipede's lair due to an earthquake, and the door of the central space is opened due to the giant slamming into the wall.

Regardless of whether this bunker is a space-time temple or not, Zhang Jun can't care about it for the time being, the demon spirit once mentioned that the space-time temple can help creatures avoid the era of mass extinction, but at this time, there are still about sixty or seventy million years before the era of mass extinction, and Zhang Jun's lifespan is only about three million years, if the fourth password chip is not found, this space-time temple is meaningless.

With Zhang Jun's summons, the dragons began to walk towards the entrance of the bunker, and the other dinosaurs avoided it. In the past few days, the volcano has long stopped, and the dinosaurs outside are gradually leaving, and they will not stay in the valley to wait for the fate of being slaughtered, so most of the herbivorous dinosaurs have left.

When Zhang Jun came up again, he didn't find the flame brute dragon family of three, the void bone dragon and the oak dragon were gone, except for the allosaurus, no other dinosaurs were left here, they went to the west, the primeval jungle five kilometers away from the bunker was not destroyed, there were still flourishing branches and leaves, which could allow them to settle down, but there were also original owners there, and after they went, they would also encounter new dangers.

Zhang Jun became the master of the bunker without paying attention, and he began to place the Allosaurus in the few large spaces closest to the gate, and brought them back to inhabit at night, and after closing the gate and the door of space, they were much safer than staying outside.

During the day, Zhang Jun still took the dragons out to hunt, because it was far away from the water source, the dragons needed to go around to the west of the valley to find prey, and they quickly resumed their original lives, repeating the game of survival and savage killing day by day.

Then Zhang Jun dug a staircase in the west of the valley that can lead to the top of the hill, so that there can be two exits, and it is more convenient to enter the western jungle.

As time passed, Zhang Jun gradually opened some bunker spaces, except for the two spaces next door that were connected in a row with the giant centipede's lair space, which were not opened, the other spaces were opened by him one after another, and there were no creatures in the other spaces, so he was more at ease.

The next day was very plain, and there were no other monsters to disturb them in the valley, Zhang Jun except for taking the dragons out to hunt every day, that is, coming back to rest and cultivate, everything went according to plan.

The creatures in the western jungle are similar to those Zhang Jun had encountered in the vicinity before, because the eastern jungle has been destroyed, so the animals have gathered here, and the food here is more abundant than before.

The dragons had no opponents in the jungle, and those Void Bone Dragons and Horned Nose Dragons would usually avoid each other when they saw the Allosaurus, but it wasn't until a few months later that the situation changed somewhat, because the once vanished Flame Brute Dragon returned, and when it returned, it also came back with a large group of Brute Dragons.

These brute dragons are not flame dragon breeds, but ordinary brute dragons, and their size is much smaller than that of flame brute dragons, generally only ten meters long, weighing six or seven tons, and they are thicker than the figure of Allosaurus, this time the flame brute dragon did not know where to bring back a group of little brothers, and their number reached about fifty.

When the Flame Brute Dragon reappeared in this jungle, Zhang Jun felt that his real enemy was coming, so at all times, he was preparing, there must be a battle between him and the Flame Brute Dragon, and this battle will determine who will dominate this jungle.

However, the Flame Brute Dragon is just another new opponent that Zhang Jun has encountered in the Jurassic, and he will encounter many such opponents one after another, and he must meet one challenge after another in order to survive.

Although Zhang Jun has the energy to continue his life, he still has to face countless dangers, and being able to live for millions of years, or even tens of millions of years, may be a miracle in itself, because it is very difficult to survive tens of millions of years without dying.

So if you can stay in an absolutely safe place and lurk, Zhang Jun is very willing, the current bunker is a good choice, but a creature needs food to survive, and it must face danger, which cannot be changed regardless of the powerful function of the bunker.

Regarding the purple powder, if he can continue his life for a long time, Zhang Jun can also consider it, but if he is allowed to stay in the bunker for tens of millions of years and eat the powder, he will definitely be suffocated inside, and his physical fitness and wisdom will gradually degrade, without the cruel baptism of nature, after tens of millions of years, if he walks out of the cave from here, he is almost a cripple, and he can easily pinch him to death if he encounters any powerful creature.

In addition, it is still unknown whether this purple powder is desirable or not, because what the giant centipede can eat, it may not be eaten by other creatures, and whether the purple powder can be generated indefinitely, is also unpredictable, and cannot be dependent on it. After thinking about it, Zhang Jun began to use the bunker as a safe place, and the brutal hunt was still staged every day.

Zhang Jun now lives alone in the central space, where the temperature has always been constant, the temperature is kept at more than 20 degrees, very comfortable, neither hot nor cold, which is probably also the system in the bunker at work.

Moreover, Zhang Jun found that the lights in the bunker can be used for a long time, and if you don't turn them off, they never seem to go out, and he doesn't know where the energy source of the lights is, so he doesn't need to think about these.
