Cheng Yu ignored their envy of the space magic weapon and directly collected the resources in the hall and his own space magic weapon.

Now that the treasure has been obtained, he now has to think about how to get out of here.

Compared with the other halls they had visited before, after the resources were removed, there seemed to be nothing else left in this hall except the remaining shelves.

When we were in the main hall below, at least there were so many paintings of humans and animals on the stone walls of the main hall, but there was nothing on the stone walls here, neither carvings nor images.

"Master, now that we have emptied everything here, why hasn't the exit appeared yet?" Elder Feng asked doubtfully.

The young master told them before that where there is treasure, there should be an exit.

But they just searched and found no exit. Now that all the treasures in this hall have been taken away by them, they didn't find any special place in this hall that can open this exit.

"I don't have the final say on this, I'm just guessing. But I still say that since there is a treasure here, then this palace will definitely not be a place of death.

Even if there is no exit back in this hall, there must be exits to other halls, and maybe the exits from this space are set up in other halls." Cheng Yu explained.

It was also the first time for him to come to this place. Although he had his own experience and experience, he could not understand everything clearly.

Besides, everyone has different ideas, and there are rules to follow for some things. The owner here may deliberately avoid these rules when designing everything here.

Therefore, he can only speculate on many things based on his own experience, but he cannot guarantee that his speculations are 100% accurate.

However, no matter how monotonous this hall is, there is at least a passage out of this place, even if it is a passage to another hall.

"These are the only shelves left in this hall. Could it be that these shelves are mechanisms that open new passages?" Elder Fan stood in front of one of the shelves and fiddled with it carefully.

The image of being locked by a stone lock before was still vivid in his mind, which made him a little more cautious and alert at all times. If there was any abnormal situation, he could ensure that he would get out of the way as soon as possible.

It's just that this shelf can't be pushed or turned. It doesn't seem to be a mechanism.

When Elder Yang and Elder Feng heard this, they checked all the shelves in the hall, but there was no reaction.

This shows that these shelves really have no secrets at all, they are just shelves used to place resources and magic weapons.

"It seems that the agency is still hidden somewhere else!" Elder Yang said as he looked around the hall.

"Look at the roof of this hall, does it imply something? I always feel that the design on the roof has another mystery!" At this time, Elder Feng raised his head and looked at the roof of the hall and said.

Several people immediately raised their heads and looked at the top of the hall. It turned out that the design of the top was indeed somewhat special.

Although none of the stone walls in this hall have carvings, the top of the hall is made up of different stone slabs that are spliced ​​together in some regular patterns. I don’t know whether it is intentional or unintentional.

"Master, there seems to be a groove on that stone slab!" Elder Fan stared at it for a while and said.

"There are indeed some circular grooves. What does this mean?" Elder Yang also wondered.

"Could these circular grooves be the secret of the mechanism?" Elder Feng said.

"It's possible! However, these grooves look a bit messy and not very obvious. If you don't look carefully, you will even be ignored." Cheng Yu looked at the large and small stone tops above his head, and there were indeed some. Circular grooves of equal size.

It's just that these grooves are not very deep, and are even a little shallow, especially under the dim light above the main hall. If you don't pay attention, you won't even notice them.

And, more importantly, he found that there were more and less circular grooves on these stone slabs, and some of the stone slabs did not even have a single groove at all. There seemed to be no pattern at all.

"I think the more chaotic and disorderly it is, the more it proves that there is some mystery behind it!" Elder Feng said.

"It can indeed be said that, but the top of such a large hall actually has such circular grooves, which means that the stone roofs of the entire hall need to be combined and studied together.

If you look at one or several stone slabs alone, it would be difficult for me to see what they are all about!" Cheng Yu nodded and said.

"I think the most important thing is that it's a bit tiring to look up at this thing like this!" Elder Yang said.

"Isn't this simple? As long as we all lie on the ground and look at the stone top, won't we not be so tired?" Elder Feng said with a smile while lying on the ground and looking at the stone top.

"This is indeed a way, but the young master is right, this hall is too big. Even if we lie down like this now, we can't see the entire situation of the entire stone top, so it will be difficult to see the mystery inside!" Elder Yang also lay down, which indeed seemed much more relaxed and comfortable.

It's just that the hall is too big, and the circular grooves on the stone slab are not very obvious, which really adds to the difficulty.

"Looking at it now, such a large and strange circular groove is indeed very likely to contain a mystery.

In this case, let's first describe the layout of the circular grooves on the top of the stone on a piece of paper. Maybe it will be easier for us to understand what this is!" Cheng Yu said.

"The young master is right, wouldn't it be better to just describe it directly? If you look at it this way, your head will look too big, too wide, and you can't understand what message it is trying to convey!" Elder Fan stood up and shook his head. He shook his head and said.

Although it is indeed easier to lie down and watch, with such a big roof, they have to connect the whole thing to watch, which is too difficult and tiring.

If it can be described and everyone looks at it on paper, it will definitely be easier to see the mystery.

"In this case, in order to save time, each of us will divide an area. Everyone will draw the grooves on their respective partitions. Then we can just put them together according to the area!" Cheng Yu said and took out a few pieces of paper. They were handed over to three people respectively.

"Okay! Okay, I'll just draw the area on the east side!" Elder Feng took the paper and pointed at the area above his head and said.

"Then I'll just paint the west area!" Elder Fan said.

Each of the four people had exactly one piece. Cheng Yu painted the southern piece, and Elder Yang painted the northern piece.

Although this thing seems easy, because the hall is very high and the grooves are shallow, it is actually very tiring to have to lift it up to find the grooves every time you paint.

It took the four of them almost four hours to search for such a large hall.

Fortunately, this place is not like the main hall below, where some living creatures suddenly jump out of the paintings on the stone wall.

Although this job is a bit tiring, it is still relatively easy to complete as long as no one disturbs me.

After the four people drew all their respective areas, Cheng Yu rejoined the four pieces of paper according to the directions of southeast, northwest and northwest.

Looking at the somewhat messy drawing paper, Cheng Yu couldn't help but frown.

"What kind of mess is this? I can't tell what is in it at all!" After the three people looked at it, they were also confused.

"No, each of the four of us has a different grasp of the distance between the circular grooves. The distance between the two circular grooves here is about one foot, but yours are all different. This is not the same as the distance between the two circular grooves on the top of the stone.

This prototype is very different!" Cheng Yu carefully compared the four drawings, then compared the stone cap above the opponent, and finally came to a conclusion.

For example, the distance between two points on the top of the stone is one foot, but when four people draw the drawing, the distance drawn by each person on the paper is different.

In this way, even if they originally drew a very simple thing, when they combined the drawings, they couldn't recognize what it was, not to mention that this thing seemed to have no rules in the first place, and it looked even more complicated.

of confusion.

"In this case, let's unify the distance and draw another picture!" Elder Feng said.

"No need, I'll just take four drawings and revise them into a complete drawing. If four more people draw together, there will inevitably be deviations in distance and position!" Cheng Yu thought for a while and said.

Although the proportions of the three of them's drawings are different from his, at least the approximate shapes and positions have been figured out.

He only needs to take his piece of paper, compare and repair the three drawings and the grooves on the stone roof, and then he can directly add it to his paper to form a complete picture of the grooves on the stone roof.

It just takes a little more time to do so.

But now that they have all the treasures, the only thing they have to do is to find the exit, so what's the point of spending some time?

"Master, how about this? You continue to repair this picture. Let's search again in the main hall to see if we can find any other clues." Elder Yang suggested.

"That's okay, but you must be careful. Once you discover anything, don't rush to take action yourself, otherwise you will be like Elder Fan again, inexplicably trapped.

Let me know as soon as there are any clues, and we will make a decision after everyone discusses it, understand?" Cheng Yu thought for a while and reminded the three of them.

Although they speculate that there may be another mystery on the top of the stone, this does not mean that the exit mechanism is really here.
