After feeling that something was wrong, Xu Ran retreated to the stone chamber and simply observed the stone chamber again.

If you look at it as a whole, this place is like an outpost, there are several stone gates, and the one he came in has a jigsaw puzzle array, which means that it is not easy to enter this outpost.

Then it is very easy to go to the broken wall and pass through the stone gate, which is completely unnecessary, the ancient people would not be so stupid.

Perhaps, the stone gate leading to the broken wall should be a door that plays a confusing role, and there may be another mystery when it really enters the place where the core is.

Xu Ran immediately thought of the role of the underground river, maybe it was ignored by him.

So, after taking the robot and going down through another underground staircase, there is another passage.

However, there are some tiny holes in the passage.

Xu Ran looked at the small holes and felt that something was not right, so he asked the robot to immediately turn on the protective measures, and he drilled into the closed cabin in the robot's abdomen again.

After the robot entered the tunnel, there were no more signs left by the working group in the tunnel.

Zizizizi!

At this moment, when the robot was about to walk near the end of the passage, suddenly water arrows suddenly erupted from those small holes.

After the water arrow is sprayed out, it still has a certain attack power, and it can actually leave shallow traces on the robot's body, and if it is a human body, it is estimated that it can be shot through.

Xu Ran felt that he was fortunate to have the foresight to get into the sealed cabin early, and after the robot began to protect the waterproof function, the extremely tough material could completely resist the attack of the strong pressure water arrow.

After passing through the area attacked by the water arrow, the water arrow immediately stopped attacking.

Two steps further down the ladder was a waterway, and most of it was almost filled with water.

"Enter Dive Mode!"

This point is not difficult for Xu Ran at all, since the scientific expedition team has entered from here, then they must have used diving equipment, which is for the robot, after turning on the diving mode, it can directly flow through the water.

After entering the waterway, it seems that this place is completely using the water flow of the underground river as a mechanism, so that there are those strong pressure water arrows before.

Further on, the water in it is alive, and the flow rate is relatively turbulent, if people do not use some borrowing points, it is estimated that they will be washed away by the current.

But for the weight of the robot, it was very easy to walk this waterway.

However, there seems to be some creature under the water, which will attack the robot from time to time, and will make a biting sound, Xu Ran scanned the eyes of the robot, and saw that it was a strange aquatic creature with teeth, looking like a tadpole, with a somewhat flat body, about a finger thick, not like a fish, nor like a salamander at all.

There are a group of those creatures underwater, about hundreds, and they will constantly attack the body of the robot, and at the same time they will bite with their teeth, but they can't bite at all, and can only bite some protruding parts without letting go.

Xu Ran didn't let the robot deal with this creature, and went up through two stairs at the end, and this section of the waterway was finished.

When the robot came out of the water, those little things still bit on the robot's body and refused to let go.

Xu Ran asked the robot to take out a few as specimens, and the others ignored it, and after walking up the stairs and walking forward for a distance, there was a gas gushing here, and the creatures fell off to the ground on their own, and then jumped into the waterway.

Xia Tanhe hadn't been here before, it seemed that Tan Nian was just trapped in the stone room, and when they returned the same way, they entered the mysterious space from other places and found the altar to escape, Xu Ran thought of the place described by Xia Tanhe that would shoot a beam of light that could have offensive energy, and it didn't exist here.

However, based on some small residues here, Xu Ran speculated that the scientific research team had definitely been here and had done scientific investigations.

There is still a door from the waterway, but it can be pushed open directly, and after coming out of a corner of the door, the space that appears again is much more spacious, and there are small bridges and flowing water, palace pavilions, stone carvings and jade statues, etc., and the buildings built are also quite spectacular.

There is a main hall in the center of the space, two side halls on the left and right, and side pavilions and altars in other directions, all of which are completely the same architectural style as the shrines where the Zhending mages enter the kingdom of heaven as described in the Zhending culture.

In fact, this so-called shrine is just a tomb built by the descendants who worship them after the death of Master Zhending.

Xu Ran didn't move around, he just looked around carefully, and found that some places on the periphery where things should be placed were empty, and I am afraid that they were looted by the scientific expedition team.

There are also some bronze and stone tools left over occasionally, but the volume is too large, Xu Ran has no interest in those big guys, even if he gets them back, he doesn't dare to take them out and sell them, and there is a risk of being invited to tea, so it is better to let them stay here forever.

After all, he had been searched by the scientific expedition team once, and among the four facilities outside the main hall of the Divine Palace, Xu Ran sent the robot out to search, but he did not find any antiques that interested him.

He saw a crack in the bronze door of the main hall from afar, and he wanted to take the robot there.

It's just that when the robot walked to the central bridge, there was a sudden vibration, and then a huge tentacle suddenly poked out of the water under the bridge and was about to roll towards the robot.

"Dodge, stand back!"

Xu Ran looked at the huge tentacles similar to the tentacles of an octopus, and after saying MMP in his heart, he immediately asked the robot to avoid danger and retreated from the bridge with a dodge.

However, the tentacle that retreated retracted, as if there was no more surprise attack, and it was estimated that it was not enough to be completely sufficient.

It's just that there is such a wide ditch under the steps in front of the main hall, which is a bit like a moat, and there is a big monster in the water, but there is only one bridge, can't it pass over the stone bridge in the center?

Xu Ran didn't want the robot to take that risk, although he was very curious about what kind of large soft creature it was, but if he wanted to probe the results at the cost of losing a robot, he would rather not, after all, the robot he brought was one of the few high-end goods that was hard to find in the fragmented city, and its value was much greater than that of the so-called tentacle monster, and he was reluctant.

Woooooo

At this time, the huge tentacle did not stick out of the water, but suddenly there was a strange sound, and the sound seemed to carry a sound wave impact.

"Boss, we have explored a strong biological brainwave magnetic field, the danger factor is high, and we need to avoid it!"

The robot then emits a warning prompt.

Xu Ran thought that this biological wave was probably the source of the biological brain wave when he came in before, and Xu Ran didn't dare to be careless, and ordered the robot to start retreating immediately.

After leaving a certain range of the central stone bridge, the shock wave weakened, and the robot shielded Xu Ran, so Xu Ran was not affected, and after the biological wave was only sent once, it gradually recovered and calmed down again.

Xu Ran thought that it was estimated that the tentacle monster should also have a limit to emit this kind of biological brainwave magnetic field, and it was impossible to send it indefinitely.

However, since there was a strong biomagnetic field here, Xu Ran felt that he was very close to finding the answer to why this place would appear when the coordinate points appeared during the debris space teleportation.

Xu Ran estimated that this was probably the source of a guiding biological force field, so the place where he teleported before should be directly above his head, if he teleported here directly, maybe he would be swept down and swallowed by the tentacle monster before he appeared, which would be a tragedy.

Xu Ran secretly congratulated himself in his heart that he was cautious enough, and changed the coordinate position when he teleported.

It's just that I was forced back by the big tentacle monster, how to get over, how did the scientific expedition personnel pass?
