I'm not sick! So do my other personalities!

Zhou Zhen, who was next to him, immediately said: "We are on the wrong road! This is not the first floor!"

Xie Qiongning came back to her senses. Although she was very confused in her heart, the facts were in front of her. She didn't talk nonsense. She nodded immediately and said: "Go back to the stairs just now and go upstairs as you said!"

With that said, the two of them ran back immediately without any hesitation.

After a while, they came to the stairs again and were about to walk upstairs when they saw a few bloated figures running down the stairs.

Under the illumination of the flashlight, it was the "Cheese Cat", "Lynx", "Pangolin", "White Elephant" and "Blue Otter"!

"Damn it! Why did I remember the wrong floor?"

"It's too dark here. I should have climbed an extra floor just now..."

"Don't make the wrong move again, I can't run anymore..."

During the breathless conversation, they met Zhou Zhen and Xie Qionning again. The two sides looked at each other with no intention of saying hello to each other.

Soon, the "Cheese Cats" disappeared into the darkness again.

Zhou Zhen immediately reminded: "Be careful, something seems not right!"

Xie Qiongning nodded. Zhou Zhen didn't need to tell her this, she could tell.

The two of them immediately walked upstairs without hesitation.

Step, step, step...

The sound of footsteps echoed monotonously in the dim stairwell.

Soon, they came to the upper floor, an unfinished rough building without many features.

There are also some temporary lines on both sides of the place. The portable flashlight that was originally nailed to the wall to serve as lighting and guidance has also been smashed into pieces and can no longer be used.

After a while, Zhou Zhen and Xie Qiongning stopped again in front of a familiar cement wall.

At this time, both of them looked very ugly.

Although the light here is dim, with only a pen-sized flashlight illuminating it, both of them are "digitally compatible" and they can tell at a glance that this is the wall just now!

They climbed one floor, but they were still on the ground floor!

After a brief silence, Xie Qiongning said immediately: "Go back and try again!"

Zhou Zhen took a deep breath and couldn't help but think of what Huang Xurong said just now... Everyone will die!

Huang Xurong is dead now, but it seems that the future of death that the other party sees is not over yet!

Thinking of this, Zhou Zhen responded: "Yeah."

As a result, Zhou Zhen and Xie Qiongning quickly came to the stairs again.

The stairs were crawling quietly, and in the darkness, it seemed like a dormant giant beast, patiently waiting for the entrance of its prey.

Xie Qiongning looked around and said quickly: "You stand here and don't move, I will go up alone."

Zhou Zhen immediately understood what she meant, immediately opened Huang Xurong's mobile phone, selected the "flashlight" function, got ready, nodded and said: "Okay!"

Step, step, step...

Xie Qiongning walked up the stairs steadily. The flashlight of her mobile phone illuminated behind the "Cheetah" doll suit, casting a huge shadow on the wall. The shadow rose step by step. Soon, she disappeared around the corner.

Calm returned to the surrounding area.

After a while, familiar footsteps came from downstairs.

Zhou Zhen looked down and saw Xie Qiongning coming out of the corner downstairs.

Zhou Zhen's expression suddenly changed.

"Penrose Stairs!"

"Penrose Stairs!"

The two of them exclaimed in surprise, and instantly understood the reason why they had not been able to get to the first floor.

[Penrose Ladder] is a geometric paradox!

The highest point of the ladder is connected to the lowest point, and there is no end!

No matter whether you keep going upstairs or downstairs, you can always go back to the starting point!

It was proposed in 1958 by the late mathematician Roger Penrose and his father, the geneticist Leonid S. Penrose.

This kind of staircase is impossible to exist in three-dimensional space, but in the field of mathematics, it is easy to realize!

The basement of this "Huangjia Club" was infected by a "digital virus"!

Thinking of this, Zhou Zhen couldn't help but feel a chill in his heart, and asked hurriedly: "What happened to you?!"

He can now confirm that everything in this unfinished building of "Huangjia Club" was normal when he and Xie Qiongning first came in, otherwise they would not be able to get in at all!

The current [Penrose Stairs] only appeared after they entered here!

In the middle... something probably happened!

At this time, Xie Qiongning had already walked up from downstairs. Her face was also very ugly. She calmed down and immediately replied: "Many accidents happened over there. Most of the people died, and I was also injured. .”

"In addition, there is a person wearing a 'Big White Goose' costume. After reading the mathematics textbook, his spirit became very abnormal. He may have been infected!"

"What happened over there?"

Accident……

Infect……

It’s Huang Xurong’s “digital domain” related to [Murphy’s Law]!

Zhou Zhen suddenly frowned, [Penrose Stairs]... Not only can they not get out now, but there is also an infected person in the basement of the "Huangjia Club"!

He is only a "first step" now. Even if Xie Qiongning and two "digital compatibility" of the "first step" join forces, it is impossible to deal with an infected person!

Even if Lu Jun arrives later, if he doesn't bring heavy firepower, he still won't be able to kill the infected!

More importantly, the infected person this time was not hit by the [Quarantine Bullet]. The other party may spread the "digital virus" to the buyers of the unfinished building at any time!

If they can't escape as soon as possible... he and Xie Qiongning will definitely die here!

Thinking of this, Zhou Zhen also quickly replied: "I caught up with the organizer of this illegal trade fair. His name is Huang Xurong. He claims to be a 'digital compatibility', but he is more like an infected person in the [incubation period]."

"His 'digital domain' is the [Moment of Death], which is related to [Murphy's Law]. It will cause everyone around him, including himself, to die due to various coincidences and accidents..."

Boom, boom, boom...

Just as he was talking, a burst of chaotic footsteps suddenly sounded in the darkness behind him.

The two immediately stopped communicating and turned to look in the direction of the footsteps.

The footsteps were very heavy. As the sound got closer and closer, the reverberation of each step became louder and louder. The entire ground shook slightly. This was not like the movement caused by human walking!

Zhou Zhen frowned and looked at Xie Qionning, then the two of them stepped back in tacit agreement.

As Xie Qiongning backed away, he turned on the pen-shaped flashlight in his hand, placed it on the ground, and pointed the light source diagonally in the direction of the footsteps.

At the same time, Zhou Zhen turned off the "flashlight" function on his mobile phone, and the two of them immediately hid in the darkness.

Soon, they retreated to hide behind a load-bearing pillar.

At this time, the footsteps were already very loud. Not only did the entire floor and load-bearing columns tremble slightly, but there was also weathered cement dust falling from the ceiling.

A bloated figure slowly emerged from the darkness.

It was a doll costume that had been stretched to the limit. From the color matching and decoration, it could be barely recognized that it was originally supposed to be a naive "big white goose". At this moment, it had completely deformed, especially the headgear, which seemed to be countless different shapes. Regular polygons are fused together, and the sound of seams cracking can be heard all the time.

This "big white goose" also held an old mathematics textbook with its deformed wings. As he walked, the other person lowered his head and kept staring at the textbook.

With every step he took, the entire building shook slightly.

It's an infected person!
