For Cheng Shuang and Liu Juan, these people were their long-time companions who had weathered countless storms together.

But for Sun Han and the others, this was their first day meeting.

Being able to cooperate and adapt to the situation is already a great favor.

As time passed, everyone grew increasingly irritable. When Cheng Shuang suggested entering the water tank, the expressions of the others changed slightly, but they did not refuse, indicating that they did not want to stay for even a moment longer.

However, they were unwilling to let a child take risks for everyone. April was the second one to volunteer to follow, simply because her height was the most suitable besides Cheng Shuang.

Du Jun thought for a moment and suggested, "What if everyone does it together?"

Liu Juan's group also noticed something amiss and contacted Sihai in advance. After communicating with Sihai using their minds, Sihai breathed a sigh of relief, "They also have a giant fish over there."

He pointed to the section that appeared to be a movable box and analyzed, "Judging from this, at least the first and last boxes are movable, and they need to be movable at the same time..."

He paused, observing the ground. There was no track for any moving object. How could such a large piece of equipment move without leaking a single drop of liquid?

Cheng Shuang noticed his confusion and then said, "Moving the head and tail can create space, and the other two fish can turn around by exchanging positions, but there's one thing that doesn't make sense."

She sat cross-legged on the ground, took out a notebook, and drew the shape of the tank. The giant fish's tank consisted of five medium-sized tanks that were connected from top to bottom. Separated by a wall was another tank with the same structure. She shaded the beginning and end of the tank. "How can it be moved without crashing?"

“Move the whole thing.” Du Jun’s cold voice rang in Cheng Shuang’s ears. The pen in her hand was taken away by the young man, who drew shadows on the walls at both ends of the tank. “One goes out and one goes in, the head on this side is connected to the tail on the other side. We thought the fish had turned around, but actually the whole tank has just been moved.”

Du Lanshan scratched his head. "What's the purpose of this? To mess with us?"

“No.” Sun Han’s eyes brightened slightly. “It’s to cover up the truth that the walls in this place can move!” He looked at everyone. “The entire water tank was moved and moved over here. The marks painted on the giant fish water tank on the next wall should still be on the outside.”

April bit her lip, glancing out of the corner of her eye at Du Lanshan, who also looked confused, and secretly breathed a sigh of relief. At least someone was there to be silly with her.

Cheng Shuang tilted her head. "Uncle Sun, do you suspect there's a hidden layer in the wall?" The little girl tapped on the glass of the water tank. "I've never understood where the green liquid comes from."

As long as these creatures are alive, they will inhale a small amount of liquid with each breath. Where does the missing liquid come from? Along the way, every water tank was full.

And do these creatures remain in this state forever? Without dying or decaying? Each one looks as fresh as if it was just put in.

“Since this place once housed us, it may have also housed other maintainers,” Cheng Shuang continued. “And where are the bodies of those who couldn’t escape?”

"The green liquid has hypnotic and brainwashing effects." Sihai wrote down all the doubts and points he had analyzed on a piece of paper, then his fingers moved as he thought, playing with the pen. "It's unreasonable that no strange people have come to manage this space for so long, but if the place that really needs to be operated is in the wall crevices, once they discover the damaged water tank..."

Du Lanshan gasped. "We'll be surrounded, and then we'll be sent back to the place where we woke up?"

"Something's not right!" April quickly noticed something amiss. "Many of the water tanks aren't touching the ceiling; the larger ones are against the wall, and the smaller ones aren't, but the path is wider on one side. Isn't the entire movement trajectory consistent?"

“Since it’s a Möbius strip, can we think of it as more than one strip?” Cheng Shuang quickly made a connected double strip, “or even multiple strips.”

"Furthermore, building a structure is different from origami."

"Why bother with all this stuff?" Du Lanshan scoffed. "Just making a fuss over nothing."

“It’s just a charade.” Du Jun looked down at the two rings in Cheng’s hands. “That’s why we still can’t confirm where the exit is.”

That truly struck a chord with everyone.

Du Lanshan immediately let out a weak yet indignant low roar, venting his frustration by ruffling his short hair into a mess.

"Actually, it's not impossible to be sure." Cheng Shuang's gaze fell on the water tank.

The group immediately understood that she wanted to go inside and explore further.

“If there really is a hidden layer in the wall, we can’t be sure how the creatures inside will react when they see us. What if they inject harmful liquid into the water tank…” Sun Han frowned. Compared to the simple exploration before, the answer was now right in front of us, but there were also more dangerous factors.

Cheng Shuang didn't care. "Which place of death isn't dangerous? If you're afraid of danger, you'll just be trapped here forever."

"Besides," she said in a low voice, her soft, sweet voice hoarse against her pale face, making her seem sinister and eerie, "capturing so many creatures can't really be for an exhibition. Even if it were an exhibition, there would have to be a clear entrance and exit. I think this place is more like a warehouse for storing experimental subjects."

The little girl looked up, chuckling as her gaze swept across everyone's faces. "We're all test subjects!"

The group's hearts skipped a beat; they suddenly sensed an unspeakable danger emanating from the child before them.

Is it just my imagination?

Everything was fine before!

Could the cramped environment have driven the child crazy?

Haven't you seen those students who stay at home studying hard, dreaming every day of tearing up their books, running wild, and being unrestrained everywhere?

The group didn't actually develop any unwarranted suspicion towards Cheng Shuang. The main reason was that the young girl genuinely understood their skills and helped them restore their ability to use them. Only a malicious enemy would go to such lengths.

Seeing the hesitation on their faces, Cheng Shuang scoffed, "I didn't ask you to take any risks, I'll do it myself." With that, she deftly drew a dagger, holding the bear cub in one hand and wielding the blade in the other, she broke a small hole in the water tank from the bottom.

The group gasped again; when did this child become so strong?

Du Lanshan and Sihai felt this particularly deeply; they couldn't possibly punch a hole in thick glass without even creating a crack.

Du Jun tilted his head, his gaze fixed on the dagger. Seeing that the dagger's blade was chipped, his expression became even more puzzled. He then looked at the little girl's tiny, delicate wrist, which could be grasped with just two fingers.

Instead, it was April who came to her senses first. She stepped directly over the small hole from which liquid was gushing out, raised her chin, and stood next to Cheng Shuang, silently demonstrating her resolve.

Cheng Shuang glanced at her but did not refuse. She took a few steps forward and quickly poked a row of holes to speed up the flow of the liquid.

As the liquid gradually drained, the giant goldfish in the tank sank to the bottom. It frantically flapped its large tail and fins, hitting the already broken glass and immediately accelerating the transformation of the hole into countless cracks.

The crack is about to spread to the entire piece of glass.

Cheng Shuang frowned slightly, took out the gun she obtained from the Resident Evil world, and swiftly and accurately delivered a fatal blow to the giant goldfish.

She deliberately ignored the gasps of her companions, used her dagger to dig a large hole along the crack, and crawled inside.
