No player objected to this proposal.

Although everyone was injured, they obviously wanted to leave this dangerous cave faster than resting and recuperating.

After briefly discussing the assignment of work, everyone lined up.

Yu Yueming walked in the front and identified the types of stones through his sense of smell.

Lu Songyan followed him and further judged through the traces around the stone to avoid errors.

The two left walked at the end of the team and did some auxiliary work, and used crayons to mark the identified stones in different colors.

Among them, there were grinding marks around, the stones with fresh smell were painted red, and the rest were painted blue.

Yu Yueming thought it would be a simple job at first, but when he actually did it, he realized that the star-shaped stones on the walls on both sides were really extraordinary, and the odor of the remaining ancients around him was too heavy.

If he wanted to accurately distinguish the type of a stone, it would take him about half a minute.

It doesn't sound much time, but after multiplying the number of stones, the total time consumption is quite considerable.

After distinguishing, Yu Yueming began to feel that his keen sense of smell became extremely dull, the differences between different odors began to become blurred, and the movements of distinguishing breath began to become mechanized.

When he becomes awesome in the future, he must find an ancient man to beat him up!

He complained in his heart, raised his forearm and rubbed his tortured nose, continuing his boring work.

Lu Songyan followed him at first, but later found that his accuracy was 100%, so she went to the wall on the other side and worked separately to speed up. However, her speed was somewhat slower, and it took about two or three minutes to accurately distinguish the type of a stone.

The group walked and stopped like this, and took a short rest in the middle. After the last stone was also identified, Yu Yueming looked at the time and found that more than seven hours had passed without realizing it.

It is now the sixth morning of their entry into the cave, and the remaining mission time is more than four days.

Lu Songyan finally counted the number of stones: "There are a total of 625 star-shaped stones here, of which 125 have worn marks on the walls around them."

"…The number is quite neat, I believe we are not looking for the wrong one."

Yu Yueming looked around the colorful walls around him and sighed.

He observed a little and found that there were five red stones located at the gap at the intersection of the two walls, while the rest were evenly distributed on the left and right sides.

However, the location of these star-shaped stones does not seem to be specific, and it is impossible to tell how to "activate" this device.

However, things may not need to be as complicated as they are.

If this is a refuge, then if the ancients hiding here want to leave, they will definitely need to remove the mechanism. Setting the mechanism to be too complicated has no meaning except to make it difficult for them to do so.

Therefore, this mechanism should have a logically simple way to resolve it.

He recalled what he saw in his notes.

Adjust the device to the right state...

He looked at the star-shaped stones and suddenly remembered the talc in the stone boxes.

Those talcs are the currencies of the ancients. But if it is a refuge, why let currencies that are not essentials occupy a large amount of limited and precious space here?

The notes said that the weirdo mentioned that those talcs have the function of storing energy.

Thinking of this, Yu Yueming walked to the stone box that had been brought to Carmen before, opened the lid, picked up a talc from it, returned to the wall, and compared the two.

After putting the two stones together, Yu Yueming found that the shapes and patterns of the two were exactly the same. The only difference was that the luster of the stones on the wall was relatively dull and the smell was not as "fresh" as the stones taken out of the stone box.

Others saw his movements and quickly followed his thinking.

"Do you think you should replace these stones?" Lu Songyan also took a star-shaped stone and compared it with the one on the wall.

"I think you can give it a try." Yu Yueming put down the stones in his mouth and explained, "Since the notes say that these stones can store energy, will the stones with wear marks on the wall be exhausted? After replenishing energy, can something be activated?"

As for those stones that have no wear marks and smell and are not fresh, it is likely to be just to cover up the "decorations" that are really arranged with stones.

The ancients may be able to easily distinguish the difference between two stones, but for other species, even if they know the principles of the device, it is difficult to distinguish the two stones.

"I heard what you said, the wear marks around the stones are indeed a bit like they were left when replacing the stones. Let me give it a try."

Lu Songyan tried to deduct a stone marked red. However, after she tried to pull it out, the stone was separated from the wall by a small slit, with no sign of falling off at all.

She pulled it a few more times without believing in her evil spirits, and after some effort, she finally successfully pulled the stone down.

The stones removed are very complete. It can be seen that they are indeed not part of the wall, but are just embedded in the wall.

Lu Songyan picked up a talc in a stone box and put it into a hole in the wall.

The moment it was embedded into the wall, the talc that had originally emitted light green fluorescent burst out with a shining light, like a bright green star lamp.

"There is a change! Then replace them all and see what will happen..."

As Lu Songyan spoke, his voice became weaker. He probably thought that it was so hard to change a stone just now, but now there are more than a hundred pieces left, what kind of despair would it be.

Yu Yueming innocently shook his front paws that he had wrapped into a bun, indicating that he could not help.

The installation of these stones should be based on the strength of the ancients. Moreover, their tentacle-like limbs can easily penetrate into the gaps around the stones and easily cut them out.

However, humans are creatures who can use tools after all. The group of people gestured at the stones, took out their knife, and pried up the stones like prying oysters.

Yu Yueming, who really couldn't help at this step, found a corner and lie down, seized the opportunity to make up for it, and tried to recover more from his injuries.

——

Nearly two hours later, the three of them finally completed their work one after another. Rong Zhicai pried off the last red stone, looked at the others, and solemnly placed the new talc on it.

When the light of the last talc bloomed, the rest of the room suddenly dimmed, leaving only these star-shaped talcs shining like stars in the night sky, casting light in the darkness.

Then, the pattern on the top of the room, which looked like a maze map, also emitted light.
Chapter completed!
