After wandering outside the cave for a while, Zhang Jun decided to enter the cave, for the sake of safety, he brought a few big dinosaurs with him, plus himself, there were a total of ten dinosaurs, and the remaining dozen or so big dinosaurs took on the responsibility of defending the group, in this valley, they were invincible, Zhang Jun did not have to worry about the safety of the dragons on the ground.

After thinking about it, Zhang Jun took a few dinosaurs to the bottom of the slope, the slope ground friction is large, not very slippery, they soon arrived at the entrance of the hole, he has taken out the glowing metal rod in the gray cloth bag, and slowly walked towards the cave with soft claws, and the other dinosaurs followed it.

Bald and Qili both curled their necks curiously and looked inside, the other Allosaurus also showed surprised eyes, and Feigo whispered a few times, it was a little afraid of the dark cave, and some reluctant to enter it.

After reaching the entrance of the cave, Zhang Jun tapped the two ends of the glowing rod with his paw a few times, and the light turned into divergent light, and he began to shine the glowing rod on the ground and the top, as well as the surrounding walls.

Zhang Jun found that this place seemed to be a man-made bunker, in front of which was an unfathomable corridor, about twenty meters wide, and there was a corridor on the left and right sides, with a width of about ten meters, the ground and the top were all flat surfaces made of silver metal, and there were some things like round holes on the top, of different sizes, which looked like lamps and other objects.

The corridor is flanked by cold metal walls, also silver, with a smooth, mirror-like wall top, and the top is twenty meters above the ground, and the surrounding area looks spacious, like the entrance to a venue where a large exhibition can be held.

On the walls and tops of the corridor, there are some columns sticking out of the wall, about ten centimeters or so of the wall, all of them are high, they are different in diameter, some are only two or three inches, some are nearly half a foot, the color is all silver and black, I don't know what they are used for. The columns were hollow, with a large hole in the middle, facing the lower hallway, which made Zhang Jun look like a mortar barrel, or a gun barrel, whatever it was, and he walked around it with some caution, trying not to get close to the direction they were aiming at.

The corridor in front of you leads straight to the front, and the corridor on the left and right sides is curved and extends to both sides, which is arc-shaped, and the arc is very rounded, and I don't know where it stretches. The light of the metal rod could not be bent, and could only shine at a distance of a few tens of meters to the left and right, and a distance of nearly a hundred meters could be seen in front of it, but there was still no end in sight.

However, the direction of this cave seems to be facing the middle of the valley, and if you go to the front, the underground should be connected to the place where the dirt bag is located in the valley, and you may find something there.

Zhang Jun carefully sniffed the smell left on the ground and the wall with his nose, and found that the giant centipedes came out and entered from the corridor on the left, because the corridor on the right and the corridor in front of them did not leave their scent and paw prints.

Zhang Jun took a closer look at the surrounding situation around the hole, and found that there seemed to be a large metal door hidden in the wall at the entrance, and this metal door could definitely close the hole, but there were no buttons or doorknobs related to opening the iron door around.

Zhang Jun took the nine dinosaurs and began to walk into the corridor on the left, he wanted to see where the giant centipedes lived first, but when it walked out about a hundred meters, the corridor forked again, and reached the three-fork intersection, and the smell of the giant centipede extended towards the fork on the right.

Zhang Jun stood at the three-way intersection and carefully illuminated the surrounding situation, and found that there was not much difference between this place and the entrance, it was all smooth walls and cold floors, he was worried that he would get lost, so he decided not to follow the direction of the giant centipede, and then turned around and walked back, returning to the entrance just now.

Then Zhang Jun began to walk towards the corridor in front of him again, this corridor is straight, so don't worry about getting lost, go all the way to the end, you can look at other places underground, and familiarize yourself with the situation here.

"Could it be that this is the Temporal Sanctuary that the demon spirit is talking about?" Zhang Jun was basically sure that this bunker was the former habitat of an intelligent creature, and thought to himself.

Now the sapient creatures were certainly gone, and if they were, they wouldn't have allowed the centipedes to run rampant inside, nor would they open the holes without any defense, and the inside was black and rumbling, without any light, not like there was any sign of sapient beings, and there was no smell of any other creatures.

The demon's description of the space-time temple is that a part of the shipwrecked ship was preserved in the explosion, and what kind of situation is inside the temple, he said in great detail, but he has some descriptions of the size and shape of the temple, and the geographical location is roughly a huge cabin buried underground, with a diameter of more than 500 meters, which is circular.

This information sounds consistent with Zhang Jun's current discovery, maybe this is the location of the Time and Space Temple, Zhang Jun's expectations in his heart are higher, and he decided to go down and see what is going on.

Zhang Jun walked in with the dragon group, and soon Zhang Jun found an intersection fifty meters away, and there were corridors on both sides of the corridor that extended out, and the corridors on both sides were still narrower than the corridors in the middle, extending in an arc, consistent with the shape of the corridor at the entrance of the cave.

Zhang Jun continued to walk in in a straight line, and found that there was this kind of corridor extending from both sides fifty meters away, and it turned out that it was about two hundred meters out of the way, plus the corridor at the entrance of the cave, there were a total of five corridors extending to both sides, all of which were arc-shaped, very regular, as if carved out of a mold.

After walking for about 200 meters, Zhang Jun found that there was no way ahead, and what appeared in front of him was a cold metal wall, which was also arc-shaped, closed and dead, and there was no place to pass.

Zhang Jun carefully illuminated the wall in front of him with a metal rod to see if there were any traces left on it, maybe there were mechanisms or doors or something like that to walk into, he carefully checked every corner with a glowing rod, but found no signs of any door, the wall was a whole, there was not the slightest crack in the middle, and there were no objects such as switch buttons and doorknobs.

"It's so exquisitely made!" Zhang Jun sighed, but he was a little disappointed and decided to go back and take a look at the corridors on both sides.

Fei Ge next to him squeaked, expressing his dislike for this black bunker, Zhang Jun was helpless, and roared at Fei Ge, signaling it to shut up, Fei Ge was a little more honest, although the other Allosaurus was also a little afraid of the dark, but they were willing to follow the leader, but they all thought that the leader was just looking for a new dragon den, and had no interest in exploring.
