The Informal Tomb Raiding Diary: She is the occupant of the tomb!-Chapter 153: Automatic Vacuum Cleaner

Standing by the entrance, I didn’t rush to go down, I asked Bi Shi if she knew who built White Jade City.

The earliest or first person to successfully reach White Jade City might have found the ’information’ about the builders.

He Su is able to develop energy on the island, she might have information that no one else has.

"It’s said... Undersea People, their ancestors established an underwater civilization, but it was later destroyed by war. This branch escaped and built this island."

"Built the island? Not built the city on the island?"

"That’s what He Su said, I didn’t ask in detail."

"Oh..."

"Did you think of something?"

"Ah~"

"Do you have speech problems, oh oh ah ah, did you think of something?"

"Yes, but I’m not telling you." I started my childish banter mode with Bi Shi again, shaking my head to annoy her.

"Your virtue, who would care to know, huh~ ptooey!"

"Let’s go, down." I jumped down the entrance first; there was no ladder below, just a direct jump of about three meters.

Bi Shi followed me, jumped down, the ground was very hard, not earth, nor stone, but felt like something...

"Yo, this seems like a shell!" Bi Shi landed and didn’t stand up, squatted on the ground and stroked the surface twice.

The ground was white, with slightly darker patterns, but there was no edge visible in any direction. If it was a shell, it would be too large.

"There’s a staircase over there." Bi Shi walked a distance forward, and there was a staircase with a chord.

The large shell seemed like a platform, the staircase spiraled downward, and I found Chen Qinghan’s markings in the corner on the left side of the staircase.

We hadn’t discussed it in advance, but I’d seen him leave such marks for his colleagues before.

Each symbol represents a meaning; this triangle signifies safety.

He was trying to tell me that this staircase is safe. I raised my eyebrows, passed by Bi Shi, boldly stepped onto the stairs, and walked briskly down.

"Hey, aren’t you afraid of traps?" Bi Shi followed behind, not slow in pace, yet she still tried to mock me.

"Someone else has already paved the way, what is there to be afraid of." I didn’t tell her about the markings, it’s our internal communication method, not convenient for others to know.

Hmm... our unit...

No need to tread carefully, we reached the bottom of the stairs in five minutes.

Though the staircase spiraled, walking quickly for five minutes meant a considerable depth.

The bottom of the spiral staircase should be vertical to the above shell platform, and the ground was also shell material.

Setting the real secret room underground so deep, maybe the treasure Old Shi mentioned really exists.

"Eh? Eyes shining, did you see something good?" Bi Shi made a discordant sound beside me.

"Humph." I ignored her, looking around, this staircase space from top to bottom should be cylindrical, the circular space below had only a door besides the staircase.

The door faced the stairs, there were no other exits, and at the lower left corner of the door panel, I found Chen Qinghan’s mark again.

It’s an arrow pointing to the right, meaning they went right.

Bi Shi walked over, pushed open the double door panel, outside was a corridor extending endlessly to both sides.

"This place is quite big." Bi Shi walked a few steps left, then turned around and walked right, craning her neck to look around for a while.

"Hmm... to the right, I can feel their presence." I pretended to close my eyes and took a deep breath.

"What, did you unlock police dog skills?" Bi Shi looked at me full of suspicion.

"Mind connection, understand? I guess not, so outdated." I didn’t plan on explaining the marks, whether she understood or not, I walked right ahead.

Bi Shi could only follow me, there were just the two of us. If one fell into a ditch, there wouldn’t be anyone around to pull up.

This place was unnaturally clean, White Jade City had been abandoned long, and maybe the underground secret room hadn’t been opened for years. Since this place had clean air, there must be ventilation, then how could the floors and walls be dust-free?

"Hey, hey?" Bi Shi nudged me with her shoulder, "This place has been sealed for years, spotless, do you think there might be that thing?"

"Which thing?"

"That thing!"

"If you don’t say the name, I can’t remember."

"Right, forgot, the dust avoidance bead."

"Oh!! What’s that?"

"Are you doing it on purpose? Do you want to die?"

"No, I’m conserving memory now to avoid becoming an idiot."

"I submit, as the name implies, it’s the energy that can keep a place or item dust-free and unchanged despite thousands of years of hardship."

"You’re saying all that to mean there’s an automatic vacuum cleaner?"

"So vulgar, unbearably vulgar!"

The two of us couldn’t have a decent conversation, every chat ended with a glare and returning to silence.

But the dust avoidance bead Bi Shi mentioned should be very valuable!

After walking silently for twenty minutes, Bi Shi spoke again: "Are we walking in place? How come after walking so long, we haven’t reached the end?"

I stopped, took out my dagger, and marked an X on the wall.

Then squatted and waited quietly, Bi Shi asked what I was doing, I said I was verifying if this corridor was a giant treadmill.

We clearly stepped forward, existing doesn’t allow walking in place, so if standing still made sense, it’s only possible we’re on a treadmill.

Because on a treadmill, you can walk ten thousand steps and still be at the same spot.

"Your imagination is wild." Bi Shi muttered, leaning against the opposite wall to rest.

I was just guessing idly, waited a while, the mark didn’t move, but it disappeared right under my nose.

The notch made by the dagger returned to smoothness, I turned hurriedly to call Bi Shi over, but turning back, I found she was gone.

"Old Bi?" I called left and right twice.

We had just come down and within half an hour, ’half’ the team had gone missing.

I felt the wall she just leaned against, cold and smooth to the touch, pushed hard but found no flip mechanism.

I returned to the wall with the X mark, damn it, the mark suddenly came back?!

"Are you done? See anything interesting?" Bi Shi’s voice suddenly appeared behind me.

I stood up and pulled her into a run, too fast for her to speak.

Until a door appeared ahead, I brought her to it and stopped.

"Are you enchanted?" Bi Shi broke free from my hand, looking at me perplexed.

"Just now, there was a spatial anomaly phenomenon." I answered while inspecting the door in front.

"No wonder after walking so long we didn’t reach the end. Hey, do you think Professor Chen and others might—"

"No! They’ve encountered similar situations before."

"True, this kind of space overlapping technology is too crude."
