“…… That's enough, do you think what happened to us is something remarkable? It's worth it. I looked at him a little unbearably, "Huh? Look! The fingers sank, and I said I was right...... But did you see how it sank just now? How do I feel as if it sank on its own? Shouldn't something come out of the blue, take it or sweep it away, or whatever? ……”

"So what's wrong with the water quality, not what's in it? …… Not necessarily, maybe it's just that it's too dark and the creature is moving too fast so we don't see it moving...... What do you think will happen to it underneath? What to expect? …… Is there a large pool connected to such a narrow opening? Used to breed some aquatic creatures with ferocious nature? Otherwise, it's so narrow, what kind of lethality can it cause...... Or is there actually a lot of poison deposited underneath, and as long as it goes, the toxin will immediately invade the limbs and hundreds of remains, causing poisoning and death? …… Hey, what kind of one would it be? The younger brother held his chin and looked at the water illuminated by the flashlight, wondering what the truth would be.

"......," I looked at my brother with a look of almost contempt, "that's why you said I was bloody. ”

"This one is not the same as that." My brother coughed dryly, avoiding my gaze.

At this time, something came up on the surface of the water, and we hurriedly leaned over to take a look.

- It was a piece of white bone, and the flesh on it had been gnawed clean. The size of the finger I dropped didn't match it very well.

“…… It's definitely not going down anymore. I looked up at my brother and said.

"Iagree" the younger brother shuddered.

"Then let's go." I told my brother to walk towards the open wall and give up his seat. Then he took another step in that direction, and finally took a big step over the dangerous "puddle".

The younger brother stood on the steps behind the wall, his head sticking out, his eyes still staring at the white bones floating on it. I was hit on the head, and finally came back to my senses, and said in amazement: "I think about it now when you stirred this small pool with your hands just now, I feel that you are really fateful......"

"I also think I'm lucky, and I'm just scared." I patted my chest with an indescribable expression, and for a moment I was afraid.

"But luckily we didn't really sneak in, and no one was hurt. Let me lead the way. He said. My brother took the flashlight from my hand. Be the first to walk forward.

"Don't go so fast, stay safe!" I whispered a reminder to him, and at the same time opened the flashlight app on my phone again.

"I see. You too, follow me. Don't get lost. He said. The younger brother disappeared into the hidden passage inside the wall.

"Hmm. I know. I nodded, quickly followed, and entered the passage.

It seems to be an upward staircase. We went all the way up. Soon, the younger brother stopped again.

"Here we are, there's a baffle. I'm guessing it's supposed to be another room above - this is supposed to be the underground passage that connects the two rooms. The younger brother said as he tried to push the baffle with his hands.

After trying for a long time, the younger brother gave up in despair: "No, it should be locked, and it can't be opened at all." ”

"Let me try." I motioned for my brother to get out of the way, and then squeezed forward myself to try to push the obstructive baffle.

"Sister, my strength should be greater than yours, can you still push if I can't push it?" My brother looked at me with some suspicion.

"Do you remember one time when the lock in your house got stuck, and who opened it with a gorgeous trick?" I squinted at him with some unpleasantness.

"But that's because you know the lock is stuck, and you can open it with just a lift...... And at that time, my thumb was injured and it was not easy to exert force. This time it's different. My brother muttered behind me.

"Don't talk nonsense, come and help me, I'll push in different directions, forward, back, left and right, you push up, maybe this is also because it's stuck." I gave him a blank look.

He pouted and reluctantly held out a hand from behind me to help.

The result is obvious - it still can't be opened.

"I said it couldn't be that simple, I guess it's another mechanism, or a key or something...... Do you think we're actually locked up from the outside? The younger brother scratched at his hair a little irritably, "Why do you think there are so many mechanisms that we need to solve?" How annoying are the brain circuits of the people who designed them? I feel like I don't want to play escape rooms again in my life......"

"It's like this outside, and it's an escape room." I was also a little frustrated, holding my mobile phone and carefully looking at every inch of the details up and down the board, "And how could there be a key in that era, are you trapped under this for too long, your brain is starved of oxygen, and then your thinking is not normal?" …… Even if you don't like it, you have to crack it, otherwise would you like us to return in vain? ”

"......" The younger brother pursed his lips and didn't answer, but he still spontaneously and reluctantly came over to help.

"Shit, there's nothing on this to give us a hint of." After searching for a long time, I punched the board in frustration, and the board immediately made a loud "duang" sound peculiar to metal, and it also brought an echo, which suddenly shook our ears and hurt.

I hurriedly held on to the vibration of the board to reduce the sound.

"Sister!! What are you doing all of a sudden?! It's going to be so loud!! Scared the hell out of me!! My brother covered his ears behind him, and only when the aftermath was completely gone did he let go of his hand and complained to me.

"I thought it was going to be thicker, I thought it wouldn't make that much noise with just a pound......" I looked uneasily overhead, wondering if someone had actually heard the loud noise up there and caught their attention...... He lowered his head in annoyance.

Suddenly, a thought flashed through my mind, and I looked up sharply again: "Huh? Wait, this material...... This is the tomb of the prince and noble, right? It won't really be ...... Huh, wait...... If this is really ...... Oh my god I know how to open this door!! We just have to scrape it hard with something sharp!! After saying that, I was so ecstatic that I grabbed my brother's arms and shook them.

"What? How do you know? Why scrape hard? Can you make it clear? My brother was instantly confused by me, and his face was surprised by "what happened". (To be continued.) )
