After walking through the long passage, the two came to a stone chamber again, and the original plan was that they should have walked back along the rope to see what was going on.

But the new stone chamber has a surprise to them.

In the left passage of the new stone chamber, which is tentatively called the second stone chamber, a long rope leads to the dark passage. Zuo Qingcang frowned, pulled the rope in his hand, and the rope in the passage in front of him also moved.

The old man said incredulously: "We're coming back again?" Could it really be a space dao technique? ”

If the four passages of the stone chamber are called the four passages of the front and back, the left and right passages, then the scene in front of them seems to be that they went out of the left passage of the stone chamber, but then walked out of the back passage.

Zuo Qingcang didn't speak, he silently walked to the position where he had marked before, and there was still nothing on it.

The old man rubbed his temples and said, "Not only the Spatial Dao Technique, but something else has erased our mark. There's something in this stone chamber! ”

"I don't think it's necessarily a space dao technique, since you said that it requires a huge amount of spiritual power, and you haven't been able to detect the existence of artificial spiritual power in front of you, then the possibility of space dao technique, we should discuss it last."

Zuo Qingcang touched his chin and said with some doubts: "Let the rope appear in front of us, it's not that there is no other way to do it." For example, if the passage we are walking is a curve, we think we are walking in a straight line, but in fact it is going around in a circle at an angle that is difficult for ordinary people to perceive, and it is not impossible for us to go back here. ”

"The problem is this mark." Zuo Qingcang looked around and said, "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 is the place we stayed in before. ”

Until this time, Zuo Qingcang's mental state remained calm, as if there was no situation in the world that could make him lose his mind. The old man on the side listened to his analysis, and his anxious mood seemed to be relieved a little bit.

"Now the emergence of this set of contradictions leads to two possibilities.

The first possibility, this stone chamber, let's call it the second chamber, is not the same place as the first one, and someone or something took the rope we left behind and went around here. If this is the possibility, then it also shows that the passage is not in a straight line, it may be a curve or even a detour, and together with many stone chambers, it forms a labyrinth. ”

"And if it's the second possibility, it means that the two stone chambers are the same, but something has erased the marks we made. But again, to achieve this possibility, it means that we are going back to the same stone chamber, which means that the passage here is not straight. ”

Zuo Qingcang said as he pulled his hands and took the rope back: "So the next thing we have to do is to verify whether there is a problem with the passage here, and if there is a problem, we will find the reason why we lost our way 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, the two of them acted separately, each holding one end of the rope, and then Zuo Qingcang returned to the No. 1 stone room. However, this is equivalent to separating oneself, in this kind of ancient tomb, acting separately is too dangerous, so Zuo Qingcang simply did not say it.

The two then walked into the dark passage, where they had to determine if it was straight.

So there is a question here, how can people be sure that they are walking in a straight line? All human movements rely on vision, relying on the surrounding reference objects to judge the distance and position, once the eyes are closed, then they tend to go in the wrong direction.

Therefore, it is impossible to determine whether human beings are walking in a straight line in the dark.

But with tools, it's much simpler. Zuo Qingcang and the old man walked over and over again, took out the night pearl in their arms, and put it where they passed by. Basically, one was placed every twenty steps, and by the time the two of them had walked two hundred steps along the passage, ten night pearls had already been placed behind them.

This is also thanks to the fact that when the two of them were preparing the Night Pearl, Zuo Qingcang specially asked to catch a few more.

When the old man turned his head to look, he could see that in the darkness, ten glowing points of light were arranged in the darkness, forming a straight line.

Yes, straight, straight and straight, without the slightest bend. Seeing this, the old man's face showed a look of disappointment: "There is no problem with this passage. ”

Zuo Qingcang nodded: "Then the only possibilities that can be thought of for the time being now are illusions and space problems." "But whether it's a collective hallucination or a spatial change, I'm afraid it's out of their range.

At this time, Zuo Qingcang suddenly thought that if the owner of the ancient tomb was really to seal the Mirage Sect, then why did he make it so complicated?

As long as he buried the entire ancient tomb, or even built a few more broken dragon stones, it was much more effective than the incomparably complex labyrinth in front of him. And this complex labyrinth in front of me is more like a lock than a permanent seal, a lock that can make it difficult for others to enter, but the owner can open it himself.

Did the people who built this tomb think that one day they would be able to enter this tomb again? If that's the case, then the deepest part of this ancient tomb is not just the body of the mirage. There must be benefits that people have to come by. ’

However, Zuo Qingcang didn't think about it after thinking about it, compared to guessing what was in the ancient tomb for the two of them, how to break through the maze in front of them was the most important thing now.

After listening to Zuo Qingcang's judgment, the old man suddenly said thoughtfully: "In fact, in addition to space and illusion, there is another possibility, that is, this passage and stone room, if they can move, can 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 a Rubik's cube, causing the stone chambers and passages to move in a way that was difficult for humans to detect, then this could indeed be the case.

Zuo Qingcang said while thinking: "Compared to the space Dao technique that requires a lot of spiritual power, and the two of us have the same collective hallucination, this is more likely. ”

The old man still had some things he didn't figure out: "But if you move, what law does it move?" Why can't we feel it? ”

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

"How did the corpse monster get back?" Zuo Qingcang's brows furrowed: "What is the difference between us and the corpse monsters?" ”
