A bizarre and terrifying experience; I messed up the dungeon world.

The monster's body was cut open. There was no blood. Only green code flowed out.

Lu Chen weaved through the horde of monsters. His butterfly knife targeted their joints, severing nerves and rendering them immobile.

She was observing Han Yingying.

Han Yingying moved faster and stronger than before. She cleaved two monsters in two with a single strike.

Lin Qi thought, she's mutating. Her body is adapting to this higher-level space. This doesn't make sense. Humans couldn't possibly complete this kind of evolution in such a short time.

A monster bypassed Chen Pi and pounced on A Jie.

Ajay is cracking the nodes of the vascular network and cannot escape.

Han Yingying was too far away. Lu Chen was entangled by three monsters.

Lin Qi is closest to A Jie.

She glanced at the tablet in A-Jie's hand.

Lin Qi thought, if the hacker dies, no one can get out.

Lin Qi threw his dagger. The dagger pierced the monster's neck. The monster paused.

Wang Jianguo chopped off the monster's head with a single stroke.

"Thanks, sis." Wang Jianguo grinned.

Lin Qi walked over and pulled back the dagger. He ignored him.

A-Jie pressed Enter. "Found it. The node is in the center. There's a data black hole there."

Han Yingying looked towards the center of the vascular network. There was a twisted black sphere there.

The center of the vascular network.

A black sphere floats in mid-air. The space around the sphere distorts. Light is swallowed up.

This is the data black hole.

"The source of this bizarre bug," A-Jie pointed to the black hole. "It's absorbing matter from the real world and converting it into game data. Ninety-nine percent complete."

Han Yingying walked to the front of the black hole.

The red lines on her arm had spread to her neck. Her skin was burning hot.

Her memories were completely restored.

Ten years ago, Han Fei inputted half of his core data into her spinal cord. The other half remained in the mainframe.

In order to obtain complete data, Zero initiated the incubation process.

"I am that lock," Han Yingying said.

Lu Chen looked at her. He didn't speak. He twirled the butterfly knife in his hand and gripped it tightly.

"How do we solve this?" Lu Chen asked.

"Use my blood." Han Yingying raised the straight knife and slashed her wrist.

Blood flowed out. Not red, but a liquid with a blue glow.

She reached her hand into the black hole.

The black hole generated a powerful suction force, pulling at her body.

The surrounding network of blood vessels began to writhe wildly.

Thousands upon thousands of monsters are swarming in from all directions. Stop them from destroying the black hole.

"Hold on!" Han Yingying shouted.

Wang Jianguo, Chen Pi, Lao Li, and Lu Chen formed a circle, protecting Han Yingying and A Jie in the middle.

Lin Qi stood outside the circle. She looked at the monsters. There were too many of them. The defensive line wouldn't hold for even a minute.

She glanced at the safe on her back.

Lin Qi thought that if this place collapsed, he wouldn't be able to take the safe out either.

She opened the safe.

It didn't contain any gold or silver treasures. It was a tube of blue reagent.

This is the first-generation gene enhancement fluid developed by Changsheng Biotechnology. It can enhance human functions in a short period of time, but at the cost of physical exhaustion.

Without hesitation, Lin Qi injected the reagent into his thigh.

Her pupils turned blue. Her muscles bulged. Her veins stood out.

Lin Qi charged into the monster horde. His speed was twice as fast as before. His two short swords transformed into a meat grinder.

She single-handedly held off the monster horde on the left.

Wang Jianguo was stunned. "Is this girl on drugs? She's so fierce."

Han Yingying's blood flowed into the black hole.

The black hole's rotation speed slows down.

A-Jie frantically typed code on his tablet. "The firewall is crumbling. Core data is being overwritten."

"Hurry up." Lu Chen slit the throat of a monster. "There are more and more monsters."

Han Yingying felt her internal energy draining away. The red lines on her arm began to fade.

The underlying logic of zero has been tampered with.

The backdoor program left by Han Fei ten years ago has been activated.

The black hole emitted a sharp cry.

Cracks cover the surface of the black hole.

"Step back!" Han Yingying pulled out her hand.

Everyone retreated.

The black hole shattered.

The blinding white light engulfed the entire space.

The system notification sounded in everyone's minds.

[Hidden Dungeon: The Underlying Logic of Zero. Completed.]

[Strange bug fix progress: 15%]

[Dropped Item: Changsheng Biotechnology Underground Base Pass.]

The white light dissipated.

They returned to their office on the 30th floor of the Changning Building.

The night sky outside the window is normal. The red eyes are gone.

Old Li lay on the ground, panting. Chen Pi sat beside him, bandaging his wounds.

Han Yingying looked at the wound on her wrist. The wound had already healed.

Lin Qi leaned against the wall. The effects of the medicine had worn off. Her face was pale. She was soaked in sweat. Her clothes clung to her body, outlining her curves.

She threw the empty safe on the ground.

"I've used the things." Lin Qi looked at Han Yingying. "Consider it a favor I owe you."

Han Yingying picked up the fallen metal pass.

"No need to owe," Han Yingying said. "The underground base. Are you going or not?"

Lin Qi looked at the pass.

She thought, "There's a higher-level enhancement fluid there. I need it."

"Go." Lin Qi stood up straight.

Lu Chen walked to the window and looked down at the street.

"This isn't over yet," Lu Chen said.

On the street, a black sedan was parked. A person in a white coat stood beside the car.

The person looked up at the window on the thirtieth floor.

He pushed up his gold-rimmed glasses.

It is Han Fei.

The floor of the control room began to shake violently. The ceiling cracked. A red light enveloped the entire room. Chapter 90

Han Yingying looked downstairs. The black sedan started. The taillights came on. The car drove out of the street and disappeared into the darkness.

"He's gone." Lu Chen withdrew his gaze.

Han Yingying put the pass into her pocket. She turned to look at A-Jie. "Check the coordinates of this thing."

Ah Jie took it. He placed the pass on the tablet to scan. The screen flashed a few times. "Basement level five. Direct elevator access."

Old Li sat on the ground. "I can't go on. I have three broken ribs. Going any further is suicide."

Chen Pi slung the tower shield over his back. "I'll stay here with Old Li. You guys go."

Wang Jianguo tucked the machete back into his waistband. He walked over and patted Chen Pi on the shoulder. "Okay. You guys find a safe place to hide. Contact us on the walkie-talkie if anything happens."

Han Yingying glanced at Lin Qi. Lin Qi leaned against the wall. The wound on his thigh was still bleeding. His black bodysuit was torn to shreds.

"And you?" Han Yingying asked.

Lin Qi straightened up. "I'll go get what I need."

Lin Qi thought, this woman just used her bare hands to bleed herself and shut down the black hole. Her regenerative abilities are beyond human comprehension. The man with the butterfly knife is also moving strangely. These two are hiding a huge secret. Following them will lead us into the core area. But I must keep my distance. If things go wrong, I must run.

Five people walked toward the elevator.

The elevator doors are intact. The indicator lights are on.

Ah Jie affixed the pass to the sensor area. After a beep, the elevator doors opened.

It was spacious inside. The metal walls gleamed coldly.

Five people went inside. Wang Jianguo pressed the button for the fifth basement level. The elevator began to descend.
