The entrance to the cave is very narrow at first, but it gradually widens as you walk in.

But the view in front of them was getting darker and darker. Only Lin Xubo and one of the foreigners each had a lighter, but the light was so dim that they couldn't even see the road under their feet.

I was a little worried about what was going on inside, since if Xiao He and the others were here, they wouldn't know we were going in now.

We have no way of distinguishing friend from foe. If a gunfight breaks out, wouldn't we die a terrible death?

After walking a few more steps, I felt even more uneasy, so I quickly grabbed Lin Xubo, who was groping his way forward in the dark.

"The lighter in your hand is too dim. I think we should do some work. We'll feel more at ease with some light. Besides, you're rushing in like this. Do you even know what's going on in there?"

Lin Xubo stopped, clearly a little scared now: "Shall we go out and get some torches?"

"Everyone's tired. Here's what we'll do: those at the back, go out and get some torches. The rest of you, rest here and conserve your energy. After all, nobody knows what we'll encounter ahead. Besides, we came out today to find the remaining missing foreigners, so we must keep ourselves in good physical condition to avoid any other accidents."

Our group naturally obeyed my orders unconditionally, while those foreigners were all cowards who feared death.

Furthermore, given the unclear situation inside the cave, continuing forward was clearly not the right choice.

At the very end were two foreigners. After Yang Rui translated what I said, the two foreigners quickly turned around and left the cave. Not long after, they returned with tree branches.

We built a campfire at the entrance of the cave and each of us made a small torch.

After resting for a while, we had recovered a lot of our strength, so we continued on our way.

At first, I thought the entire cave had been blown open, but after walking for a short while, we discovered that the cave in front of us was actually empty.

This was obviously formed naturally, except that the outer entrance was blown open.

Wang Ping walked beside me, looking around with a puzzled expression. "If it really was Xiao He and his group who did it, how did they know the mountain was hollow? And why would they blow it up?"

Before I could answer, Yang Rui appeared out of nowhere and looked at Wang Ping very seriously, saying, "I guess they must have brought instruments with them when they came. After all, they came prepared. I don't know much about them, but the fact that they were able to blast this mountain open so accurately means there must be something inside."

After saying that, he walked past me and Wang Ping to the front, and stood side by side with Lin Xubo. The firelight in their hands flickered as they walked.

Wang Ping watched Yang Rui's retreating figure, tugged at me, and said in a deep voice, "I always feel that there's something strange about this Yang Rui."

I nodded in agreement. I had this feeling about Wang Ping a long time ago, but he has been living in our camp for so long. If we kick him out now, he might be able to find Xiao He and the others, but if he can't, how will he survive on this deserted island by himself?

"Forget it, no matter how strange he is, we don't need to care. As long as he doesn't threaten our safety, let him do whatever he wants. Watch your step, let's keep walking. If we haven't reached the end yet after walking for a while, I think we should turn back."

Wang Ping nodded, and we walked for a while longer. Then, Lin Xubo and Yang Rui, who were ahead of us, suddenly stopped.

The male colleagues following behind also naturally stopped in their tracks.

Then I saw them turn their heads to look at the stone wall in perfect unison.

Seeing their actions, I was first taken aback, and then I wondered what was wrong with them.

Is there no road ahead?

Wang Ping was also very puzzled. He quickly took a few steps forward and then I saw him slowly turn around and look at the stone wall.

Just as I was about to ask Wang Ping what was going on, I saw him raise the torch high and then move his head back and forth as if he were observing something. I quickly took a few steps to Wang Ping's side.

Only then did they realize that Wang Ping and the others were looking at the stone wall, which was covered in vibrant colors. Upon closer inspection, the colors even appeared to follow a pattern.

Lin Xubo and the others took a few more steps forward, and I heard Yang Rui say with great surprise.

"Brother Sihai, this looks like a mural! Come and take a look!"

I was stunned when I heard that. How could there be murals in such a strange cave? Could this be the site of some ancient people?

Despite my doubts, I quickly walked to Yang Rui's side. Following the direction Yang Rui was pointing, I glanced at it and found that it was indeed a mural. The colors were vibrant, and the words inside were very vivid. Although the lines were simple, the things depicted were easy to understand at a glance.

This mural is very large in scale and uses very bold colors.

All I could see was a group of people pulling many carts filled with strange-looking things, which looked like stones, but with yellow paint used to simply outline the stones with light.

Those who were pulling the car all had expressions of extraordinary joy on their faces.

The sea was even shimmering with golden light.

As Yang Rui looked at it, he clicked his tongue in amazement: "Wow, this mural looks quite old, and you see, it seems to be a narrative mural. The things they're carrying in their carts aren't stones, they're gold!"

Lin Xubo, who was still observing the murals in front of him, immediately became excited when he heard Yang Rui say this: "It seems that there really is a gold mine here. Look at how much they have loaded in these cars, which means that the gold mine here must be huge. If we can find it, what will we have to worry about?"

Hearing Lin Xubo's words, Wang Ping couldn't help but retort, "Hmph, do you think things are as simple as you imagine? Even if there's a gold mine here, can you get out even if you find it? Gold can't circulate here at all. What's the use of finding a lot?"

Lin Xubo listened to Wang Ping, but Wang Ping disagreed at this moment.

"That's not right. We can always get out of here, right? Besides, Yang Rui and his gang still have transportation. As long as we find them, we can bribe them with a lot of money. They can't possibly disagree then. Anyway, there's no point in staying here. There are wild wolves and dogs everywhere. We should go back to the city and enjoy life."

I listened to Lin Xubo and Wang Ping bickering, but I had no interest in paying attention to them at all. Instead, I looked at the murals on the island and felt that this deserted island was so mysterious that I couldn't even imagine it.
