It was already about seven o'clock in the evening, and the city was brightly lit.

For the pitch-black environment, Xu Ran has long been accustomed to the fragmented city.

In addition, he also has seven robot helpers who are always focused on his safety, and such an exploration team is completely safer and more reliable than the human exploration team.

Because all actions are centered on Xu Ran's will, these robots will do whatever Xu Ran asks them to do, unlike the human team, which has different intentions and is selfish when in danger.

Swish!

In the pitch black environment, all of a sudden, the robot in front of it will turn on according to the light, and it will immediately illuminate the surrounding environment.

Strictly speaking, this is like a cave with a large scale, and Xu Ran analyzed the data of the ancient tomb of Wusha Haigouzi left to him by Song Wenli, and this is the palace hall of the ancient cemetery.

Originally, when Xu Ran was teleporting coordinates in the fragmented city, he planned to go directly to the three-dimensional coordinate location that he had calculated as marked by the Xixia Silk Book.

But after thinking about it, Xu Ran gave up this plan, he didn't know if the guiding force field in that place tended to be stable, in case it couldn't support him and the energy of the seven robots, once it collapsed, then Xu Ran would cry without ground.

So Xu Ran changed the coordinate position slightly, and when the debris space teleported back to the earth, he directly teleported to the ancient tomb through the coordinate point displayed on the dimensional surface that he had been exploring for a long time.

The result was exactly the same as Xu Ran expected, a star map light point he had found on the space key came from this ancient tomb.

So Xu Ran proved this point through this teleportation experiment.

However, after the position of the coordinates was changed slightly, Xu Ran was now teleported to the location of the side hall of the Ancient Tomb Palace, and in front of him was a passage that had already been opened.

However, there is a guiding energy force field that plays a role under the ancient tomb, indicating that its coverage includes this side hall, otherwise the place where Xu Ran was teleported over would not be here.

According to this conjecture, the guiding force field hidden in this ancient tomb was almost comparable to the large teleportation point arranged by Xu Ran, which still surprised him very much.

This side hall is not the core of the tomb, but it is not on the edge either.

Judging from the structural diagram inside the ancient tomb, he was not far from the passage that Xia Tanhe had accidentally discovered and the location of the more hidden underground palace.

Now that it has been teleported, several robots are currently surrounding Xu Ran, and they have all turned on the headlights, and Xu Ran can see the situation in this ancient tomb clearly.

This side hall should be the place where some sacrifices were placed in the ancient cemetery palace, but now it is empty, except for some very heavy ones that cannot be moved away for the time being, and the other antique items have been looted by the archaeological team.

However, Xu Ran's goal is not to pick up the leaks and find those leftover antiques here, mainly to explore and investigate here, so he doesn't care.

"Boss, find the entrance to the passage, everything is detected and safe!"

At this time, a robot has found a hidden entrance, and has explored and reported on the safety factor in the entrance.

In fact, this place has already been investigated by the working group, and if there is danger, there will definitely be a hint.

The work of the robot is very rigorous, in order to ensure Xu Ran's safety, they will naturally do another investigation when Xu Ran opens the way.

According to the entrance prompted by the robot, Xu Ran walked into the passage.

The passage is a downward slope, flanked by stone walls, as if they had been carved out of the mountain, and there are no unusual plants around, apparently cleaned by the archaeologists.

Walk along this passage for about ten meters, you will find two forks, but there is a small sign at the fork, which is marked with arrows, and also draws diagrams and text markings, which is very convenient for Xu Ran to make the most accurate choice and judgment.

Xu Ran chose the passage where the underground river was discovered, and there were robots in front of him along the way to probe, Xu Ran seemed to be traveling here, looking here and there, and did not encounter any dangerous situations.

After all, there have been scientific research teams in these places that have been explored and studied here, and the safety factor here has been reduced to a minimum.

Xu Ran was just thinking about some of the experiences they had of entering this place that Xia Tanhe told him at that time, as well as some of the situations that happened at that time.

According to Xia Tanhe, after they entered this passage, because of a mysterious energy interference, they first saw an illusion here, and then a mysterious thing that was non-living and non-metal attacked them.

After they were attacked, they were ready to return the same way, but the illusion brought by the energy interference took them to which channel, and then they were attacked by mysterious energy arrows, and it was because of this that Song Wenli was injured, Xia Tanhe took Song Wenli into a huge space in a panic, and then saw an altar, and was teleported out by the altar.

"Professor, a stream of biological brainwave interference has been detected!"

At this time, as he continued to go deeper, a robot exploring in front of him sent out a report.

However, when Xu Ran received the report, he suddenly felt a buzzing sensation in his brain, and he was a little dizzy.

"Turn on the protective measures, the striker continues to probe, block the interference!"

Chirping!

Just when Xu Ran felt a little dizzy and gave the order, the working robot that had been temporarily transformed by An An who had been following Xu Ran's side gradually opened a cabin in its abdomen, and the robot grabbed Xu Ran, and then sent it into the cabin and sealed it.

After Xu Ran entered the cabin, he immediately felt that those abnormalities disappeared immediately, and at the same time, he could see the situation outside through the glass.

Through the robot's guidance, Xu Ran found the instruments that were placed there in a corner, but those instruments were turned off because of the loss of power supply.

The instruments that Xu Ran recognized were all used by the scientific research team, but I don't know why they didn't take all these instruments away, but stayed here.

The main function of those instruments is to shield abnormal signal wave interference, otherwise the members of the working group will also encounter this kind of situation that Xu Ran empathizes with after entering here, and may get lost in it.

Xu Ran didn't move those instruments, nor did he plan to let the robot provide power to those instruments to turn on, the robot itself has the function of shielding signal wave interference, which is more powerful than those instruments.

Of course, the robots were not disturbed, and they continued to take Xu Ran deeper.

At a distance forward, the space opened up.

However, the robot stopped when it walked around, and even Xu Ran could see that there were some strange holes, like very smooth holes cut by a laser, as if there were some mechanical monsters inside.

Swish!

Suddenly, as a robot probed the hole, a strange thing came out of the hole and attacked the robot.
