Walking through the long passage, the two of them came to a stone chamber again. The original plan should be that they walked back along the rope to see what was going on.

But the newly appeared stone chamber happened again, which surprised them.

In the left passage of the new stone chamber, which is temporarily called the No. 2 stone chamber, a long rope leads to the pitch-black passage. Zuo Qingcang frowned and pulled the rope in his hand. The rope in the passage in front of him also moved.

The old man said incredibly: "We are back again? Is it really a space Taoist technique?"

If the four passages of the stone chamber are called the four passages of the front, back, left and right, then the scene in front of them looks like they walked out of the left passage of the stone chamber, but then walked out of the rear passage.

Zuo Qingcang didn't say anything. He silently walked to the position where he had marked it before, but there was still nothing on it.

The old man rubbed his temples and said, "Not only is the space Taoist technique, but something else has erased our marks. There is something in this stone chamber!"

"I don't think it is space Taoism. Since you said that it requires huge spiritual power and you have not been able to detect the existence of artificially guiding spiritual power, then we should discuss the possibility of space Taoism in the end."

Zuo Qingcang touched his chin and said with some confusion: "It is not impossible to let the rope appear in front of us. For example, if the passage we are walking on is a curve and we think we are walking in a straight line, but in fact, he is walking around a circle at an angle that is difficult for ordinary people to detect and wrapping us back here, it is not impossible."

"The problem is this mark." Zuo Qingcang said, looking around: "The disappearance of the mark and the appearance of the rope are a set of contradictions, making it difficult for us to judge whether this place was where we were before."

Until this time, Zuo Qingcang's mental state remained calm, as if nothing in the world could make him lose his mind. The old man next to him seemed to relieve his anxiety little by little as he listened to his analysis.

"The emergence of this set of contradictions now leads to two possibilities.

The first possibility is that this stone chamber, called the second stone chamber, is not the same place as the first stone chamber before. Someone or something takes away the rope we left and then goes around here. If this is the possibility, it also means that the passage does not go straight, it may be curved or even circling, and together with many stone chambers, it forms a maze."

"If it is the second possibility, it means that the two stone chambers are the same, but something erases the mark we made. But the same way, to achieve this possibility means that we have gone back to the same stone chamber, which means that the passage here is not straight."

Zuo Qingcang said, pulling his hands and retracting the rope: "So what we have to do next is to verify whether there is any problem with the passage here. If there is any problem, we will find the reason why we were lost before."

What Zuo Qingcang didn't say in his heart was that there was actually a more effective way to verify the situation in front of him, that is, they acted separately, each holding one end of the rope, and then Zuo Qingcang returned to the No. 1 stone chamber. However, this is equivalent to being separated by himself. In such an ancient tomb, it is too dangerous to act separately, so Zuo Qingcang simply did not say it.

Next, the two walked into the dark passage, where they wanted to determine whether the passage was straight.

Then there is a question here. How do people determine whether they are walking in a straight line? All human movements rely on vision and reference objects around them to judge distance and position. Once you close your eyes, you will often go in a deviant direction.

Therefore, relying solely on humans, we cannot confirm in the dark whether we are in a straight line.

However, relying on tools is much simpler. Zuo Qingcang and the old man walked over and took out the night pearl in their arms and placed it where they passed by. Basically, one was placed for every twenty steps. When the two walked two hundred steps along the passage, ten night pearls were already placed behind them.

This is also thanks to the two of them preparing for the Night Pearl, Zuo Qingcang specially asked to grab a few more with them.

The old man turned his head and saw a darkness, where ten fluorescent light spots arranged in the darkness, forming a straight line.

Yes, straight, straight, without any curvature. Seeing this, the old man showed a look of disappointment on his face: "There is no problem with this passage."

Zuo Qingcang nodded: "Then the possibilities that can be imagined for the time being are hallucinations and spatial issues." But whether it is collective illusions or spatial changes, they may have exceeded their response range.

At this time, Zuo Qingcang suddenly thought, if the owner of the ancient tomb was really to seal the Mirage Sect, why would he have made it so complicated?

As long as he buried the entire ancient tomb or even made a few more dragon-breaking stones, it was much more effective than the extremely complex maze in front of him. Compared to the permanent seal, the complex maze in front of him is more like a lock, a lock that can be difficult for others to enter but the owner can open it himself.

‘Are the person who built this ancient tomb thinking that one day he could enter this ancient tomb again? If so, then the deepest part of this ancient tomb is not just the corpse of the Mirage Sect. It must have benefits that people must come to know."

However, Zuo Qingcang thought about it and stopped thinking about it. Compared to guessing what was in the ancient tomb, how to break through the maze in front of them is the most important thing.

After listening to Zuo Qingcang's judgment, the old man suddenly thoughtfully: "In fact, in addition to space and illusions, there is another possibility, that is, this passage and stone chamber. If they can move, can it also cause this effect?"

Zuo Qingcang immediately understood what the other party meant. If these stone chambers and passages formed a large mechanism similar to the Rubik's Cube, causing the stone chambers and passages to move in ways that are difficult for humans to detect, then this could indeed be caused.

Zuo Qingcang said while thinking: "Compared with the space Taoist technique that requires a lot of spiritual power, and the two of us were hit by the same collective illusion, this is more likely."

The old man still couldn't figure out something: "But if we move, we follow what pattern. Why can't we feel it?"

Zuo Qingcang suddenly remembered: "Do you still remember those corpse monsters? If the Taoist priests who robbed the tomb were also trapped here, then why might the corpse monsters return to the entrance?"
