"This formation itself is carved by themselves, and since they can depict the formation themselves, it is natural that they can draw it again. But Senior Brother Yu, including all of us, had never seen such a formation. If this formation fails, we can't re-carve it, so they can successfully stop us here!" said Xinhai with frustration.

These guys are really vicious, if it is really as you say, this is really not a simple problem. Xinluo said.

"Actually, don't be so pessimistic, maybe the problem is not as complicated as you think!" said the White Devil.

"Oh, what does Bai Lao think?" asked Xinhe.

"Although the old man is not very proficient in formation, and even has a world of difference from the formation master, I also understand a truth. That is, it is not a simple matter to depict a formation.

I just took a look at that formation, don't underestimate this formation, although this formation looks small and seems to be very simple. But when I studied the front chart, it was very complicated.

Therefore, I think that even if it is a formation master, it is not easy to portray such a small and fine, refined and complex formation.

I've heard from you, too, that these builders seem to have sealed something important underneath this. If this is the case, they are so covertly leaving a way back for themselves, obviously for emergency purposes. In the event of an emergency happening to something below, they are able to open the way to the bottom in a short period of time.

If this formation has failed, or even been destroyed by them, it needs to be portrayed. They don't want to complete this formation in a short period of time, how can they go to the rescue?" the White Devil explained to everyone carefully.

"Yes, Bai Lao is right, the role of them in leaving this back road is to save themselves. Even though they knew that it might give us a way out, they couldn't help it.

If this thing is turned into a scrap, it will not be a matter of time for them to carve the formation themselves. In this way, they should be able to maintain the integrity of this formation, at most, it is just to cut it off in some important place!" Xinluo said very approvingly.

"There's another important reason why I say that, if they really want to stop us, there are a lot of ways. You see, this thing needs a total of two hedrons. If he had taken both hedrons at the same time, we would have no way of knowing what was in the two empty slots. Why did they bother to destroy the formation so complicated?

In addition, if the formation is too badly damaged, even to the point that it cannot be repaired, it means that this thing is useless, they shouldn't be so stupid, right? Do they have to make a new one?"

"Hehe, that's what I said, but if they take this spirit crystal away, we may not know what is in this empty slot, because we have already found out from that boss that there is some kind of crystal placed underneath, even if we try, I believe we can test that it is a spirit crystal. Xinhai thought for a moment and said.

"Maybe, but I don't think the problem just now was in the formation!" the White Devil said again.

"Why?" the crowd wondered.

"As I said earlier, if they really want to embarrass us, they can take this piece of spirit crystal with them. In that case, you may be able to guess that this is where the spirit crystals are placed. But not all of them will find the hedron underneath that boss.

Maybe others only found these four traps, then they had no way of knowing that these two empty slots should be placed with hedrons. So wouldn't they be better able to stop us?

Moreover, if my guess is correct, the spirit crystals on these two slots are respectively open to the formations that come and go. And we have a gap left in this formation here, the middle formation should have no gap, both slots have spirit crystals, then the bottom formation should also leave a gap, and that empty groove is used to open the formation when you come up.

Judging from the current situation, since he sealed things underneath, there should be no exit below, so they will build such a hidden back road to lead below.

In this case, they can only leave from here, and after leaving, they can completely take away all the two spirit crystals, so even if we find this thing, and we don't know that it is a spirit crystal placed here, naturally there is no way to activate this formation.

And when they came over, they put back two spirit crystals at the same time, so that not only opened the formation leading to the bottom, but also ensured that when they came back from below, they only needed to place a spirit crystal in the formation below to activate the formation.

But now that he has left a piece of spirit crystal, we don't even need to think about it to know that this other empty slot is also where spirit crystals are placed. Moreover, if we still want to come up from below, we can just place a spirit crystal underneath, and we don't have to worry that there is no spirit crystal in this empty slot, which is too hidden.

So, I think that since they have done this, maybe they are not going to kill us as we thought, but they have left us a way to live, and it depends on whether we can go on or not.

After all, not everyone has spirit crystals, and we happen to have them because of the young master. But if the others come in, I'm afraid that even if they see such a formation in front of them, there is no spirit crystal to open the formation for them, I think this is what they want to embarrass us, not the formation itself!"

"Bai Lao's analysis is very reasonable, but Bai Lao, do you think they didn't leave from here? If the exit is below and they leave from below, will the formation below be empty for both slots?" Xinyun asked with some concern.

"In that case, wouldn't we be able to activate the formation leading to the bottom by putting the spirit crystal on it?"

"Yes, this is actually what I'm most worried about, and I'm also worried that if the real exit is underneath, it will be really troublesome, then there is a high probability that both slots on the formation slot below will be empty, so the young master will not react when he puts this spirit crystal on it!"

"This shouldn't be possible, didn't you say before that he sealed something important underneath, won't there be an exit below?"

"But you also told me before that you can't get out of here, so how did they get out of here? So it's not impossible that the exit is below, so I'm a little worried about this now, but now it's all speculation, maybe the bottom is really not the exit!"
