That secret passage is hidden in a remote corner of the ancient tomb, when the archaeological team came in to explore for so long but did not find it, and then it was at the end of the working group's investigation mission, and it was accidentally discovered by Song Wenli and several others.

And that discovery, but there were a lot of accidents, if it weren't for Xia Tanhe always guarding Song Wenli and entering the altar space by mistake, otherwise they would have to explain to them at that time, and Song Wenli would probably not be spared.

Therefore, for that secret passage, the risk coefficient given by the scientific research work that came in later to investigate was still relatively high for the ancient tomb.

When Xu Ran teleported in through the teleportation point, he had also experienced the interference of biological waves in the secret passage, and he had also discovered the attack of energy beams, but he had a team of robots, so he was not afraid of these, and everything could be easily dealt with and resolved.

However, this time, although there is no shortage of experts and powerful guards in the adventure team of the Fire Family, and the configuration of those advanced weapons and auxiliary instruments are all the world's top scientific and technological products, the level of such an adventure team is still very high compared to the archaeological team, including the level of protection.

It's just that I didn't expect that someone would enter the secret passage, and the state would happen.

Judging from the direction from which the scream came, Xu Ran could hear that it was in the section where there was a biological wave attack, and at the same time, it would make people hallucinate.

After hearing the screams, Captain Li of the security team immediately asked an agent with medical personnel to quickly rush over to investigate.

Because of the accident, Xu Ran and Huo Si Fal stayed outside for the time being, and did not enter the secret passage immediately.

After a while, the medical staff rushed back with the agent, and Xu Ran saw that the person on the agent's back was not a companion of the group of mercenaries, but an apprentice assistant who had given the master of the company a hand.

No one thought that it would be even the master's person who had an accident, and his psychological quality was so poor, because after the interference attack of the biological wave made him hallucinate, it seemed to have triggered some terrifying demons, and he was scared like this, and he scratched himself, which really made people laugh and cry.

However, Master Lian's face was so black that he couldn't be darker, this incident made him feel very embarrassed, they were in the tomb robbery business, and he hadn't seen any scenes in the ancient tomb, but he didn't expect that it was his disciple who had a situation in the first place, and he was scared like this, compared with his previous performance, his psychological quality was so unbearable, which made him feel even more disappointed.

There are logistics personnel in the team who are responsible for these, and Huo Sifar saw that Master Nalian's disciple only scratched himself after being mentally stimulated, although it was not very serious, but the mental problem must be treated carefully.

Since he was injured, he would definitely not continue to advance, so he sent this person back to the base, and after the person who was moving forward explained the general precautions, the team continued to march.

After Xu Ran entered the secret passage and walked for a while, someone immediately came over to remind them to put on the earplugs that had been prepared in their backpacks for a long time.

The earbuds are also a communicator, which can block out some voice or sonic interference, and at the same time keep in touch with the people in the team and hear what they are saying.

In fact, even after having this headset, there will still be a biological wave that will drill into people's brains after entering, which will still have a little impact.

Xu Ran had already tried that biological wave, and he had his own way of dealing with it, plus he had the ability to telepathize, so he was immune to that biological wave.

However, Luo Hongtao beside him suddenly became a little demented for some reason, Xu Ran saw that he had hallucination symptoms, so he suddenly slapped Luo Hongtao on the back of the neck, Luo Hongtao came back to his senses and smiled slightly embarrassed at Xu Ran.

In fact, that kind of biological wave is easy for some people who are not strong in willpower.

But the people who came in later were not as unbearable as the disciples of the previous master, they were only slightly stunned, some got rid of it on their own, and some were shocked from the side, and some were also free from the influence of that illusion.

However, the further he went, the more Xu Ran noticed that something was wrong.

Because the biowave would get stronger and stronger, and the frequency was twice as strong as the last time he encountered it, even if the agents in front of him placed the jamming device, the biowave frequency was still not blocked.

At this time, it will be better when the music is played in the ears.

After walking through the passage with biological wave interference, there was a mechanism array, and the agents in front and the experts such as Master Lian had already cracked these trap arrays, and the people in the middle and back of the team passed by without any worries at all.

It's just that Xu Ran couldn't help frowning after paying a slight attention when he passed by the trap array.

The last time he came, he also passed through this trap array, and he had an impression, but when he looked at the trap here now, it was completely different from the last time, the last time it was like a metal machine with many fine pores as thin as hair, and it would release a kind of beam.

But this time it was completely different, the holes were magnified, and there were some broken arrows exposed, obviously some arrow holes.

The difference is also that there should be a fork in the road further on, and you can choose two forks to go to different places.

But now it suddenly became a kind of labyrinthine terrain, as if many stone pillars had suddenly come out of the ground to block some places, and the fork in the road was gone.

Xu Ran followed the team and walked half a way forward, and he felt even more strange, because he found that what he saw when he came in this time was completely different from the last time, and there had been a lot of changes.

According to the last memory, after bypassing those traps through this passage, there will be a stone chamber, which is actually an outpost before entering the temple.

If you pass through one of the doors of the stone chamber, you can find a wide crack, and you can see many different styles of tombs in the tomb.

At the front of the team, there were those agent-level personnel exploring the way, and no experts were cracking those mechanisms, so the progress was relatively fast, and the people who followed up did not encounter any danger.

So soon, Xu Ran followed the people in front of the team to the stone chamber, but the people in front paused and explored.

After Xu Ran entered the stone chamber, he found that although the stone chamber was still there, the waterway leading to the underground river was gone.

At the same time, he looked through the stone chamber in another direction, and found that the big crack was gone, and he could not see the tombs of different styles, and some were only those sand and stones, as if the place had been completely cut off after some sudden earthquake.

The stone room is still the same stone room, Xu Ran looked at the things left by the Central Plains scientific research team in the stone room, although the things were still there, he just felt that something was wrong.

What's wrong?

After seeing the topographic map hanging on the wall, Xu Ran suddenly understood that something was wrong, and this direction felt deviated.

But how can this be, and why does the sense of orientation bias occur?
