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

Han Yingying lowered her head. The blade grazed her back, tearing her clothes.

Lu Chen watched from the doorway. He didn't interfere. He knew Han Yingying could handle it.

Han Yingying turned around. A straight knife was held against Lin Qi's neck.

Lin Qi stopped what he was doing and looked at Han Yingying.

"Not bad," Han Yingying said. "Which guild are you from?"

"A free spirit," Lin Qi said. His voice was cold.

"A lone wolf came to Nirvana headquarters to steal something." Han Yingying sheathed her knife. "What's your name?"

"Lin Qi".

"What do you need the hard drive for?" Han Yingying asked.

"Sell it for money," Lin Qi said.

Han Yingying looked into Lin Qi's eyes. She was lying.

Just then, the entire building began to shake violently.

The coating on the wall began to peel off, revealing red cartilage tissue underneath.

The floor cracked. Blue liquid gushed out of the crack.

A system notification sounded in the minds of the three people.

[Warning. Reality space overlaps.]

[Hidden dungeon triggered: Ruins of the Immortal Creatures.]

[Difficulty: SS rank.]

[Mission Objective: Locate the core data. Survive until the end of the instance.]

Han Yingying looked around at the changes. The office had been transformed into a dilapidated laboratory.

The mahogany door was replaced by a rusty iron door.

"Ah Jie." Han Yingying pressed the earpiece.

"Boss, something's happened. We were downstairs, and we got pulled in too." Ah Jie's voice was panicked.

"Where are Jianguo and Lao Li?"

"Everyone's here. Chenpi has arrived too. We're in a big hall now," A-Jie said.

"Stay put. We'll come find you," Han Yingying said.

She turned to look at Lin Qi.

Lin Qi gripped the remaining short knife in his hand, watching Han Yingying and Lu Chen warily.

Lin Qi thought. SS-level dungeon. I can't survive alone. These two are very strong. I can use them.

"Want to team up?" Lin Qi asked.

Han Yingying looked at her. "Just don't hold us back."

The laboratory was filled with the smell of formaldehyde.

The indicator lights on the wall were flashing red. The floor was covered in white tiles, which were stained with dried blood.

Han Yingying walked in front. Lu Chen walked on the left. Lin Qi walked on the right.

Lin Qi walked to the side, maintaining a safe distance from them.

Lin Qi observed Han Yingying. This woman walked with perfectly synchronized strides. Her gaze constantly scanned blind spots. She hadn't sheathed the knife in her hand.

Lin Qi looked at Lu Chen again. This man was like a shadow. His presence was very low. But his hand holding the knife was very steady.

Lin Qi thought. These two are top-tier players. Why haven't I heard of them before?

The three walked out of the laboratory. It was a long corridor.

At the end of the corridor was a glass door.

Behind the glass doors is the lobby.

Wang Jianguo stood in the middle of the hall, holding a brand-new Gatling gun. Old Li held an automatic rifle. Chen Pi held up a brand-new black tower shield. A-Jie was fiddling with a tablet.

"Boss. Over here." Ah Jie waved.

Han Yingying pushed open the glass door and walked over.

Wang Jianguo looked at Lin Qi behind Han Yingying.

"Who is this beautiful woman?" Wang Jianguo asked.

"Lin Qi. Temporary teammate," Han Yingying said.

Lin Qi didn't look at them. She leaned against the wall, wiping the short knife in her hand.

Wang Jianguo leaned closer. "Hey beautiful. Which guild are you from? Let's add each other as friends."

Lin Qi looked up and glanced at Wang Jianguo. His eyes were cold.

"Get lost," Lin Qi said.

Wang Jianguo got a cold shoulder. He touched his nose and walked back.

"What a temper," Wang Jianguo muttered. "Even colder than you." He glanced at Han Yingying.

"Let's get down to business." Han Yingying looked at A-Jie. "What did you find out?"

"This is Changsheng Biotechnology's underground laboratory from ten years ago." A-Jie handed the tablet to Han Yingying. "The system has overlaid the real world with data from ten years ago. We are now in a semi-real, semi-virtual space."

Han Yingying looked at the map on the screen.

The laboratory has three floors. They are currently on the first floor.

The core data is in the main control room on the third floor.

"Go downstairs." Han Yingying handed the tablet back to A-Jie.

Chen Pi, holding the tower shield, walked at the front. Han Yingying and Lu Chen followed behind. Lao Li and Wang Jianguo were in the middle. A Jie was protected at the very back. Lin Qi walked at the very back.

Lin Qi observed their formation. A standard combat squad. Clear division of labor.

One side of the hall has a downward staircase.

The staircase was wide. There were no lights. It was pitch black inside.

Han Yingying took out a flashlight and illuminated the steps ahead.

Chenpi stepped onto the first step.

Heavy breathing could be heard in the darkness.

There's something down there.

"Prepare for battle," Han Yingying said.

The panting grew closer.

A huge dark shadow climbed up from the bottom of the stairs.

The flashlight beam shone on it.

It is a monster pieced together from countless severed limbs.

It is three meters tall. Its body is obese. Its body is covered in hands and feet. It has no head. There is a huge mouth on its chest, filled with serrated teeth.

[Frankenstein's monster. Level 60.]

"What is this thing? It looks so sloppy," Wang Jianguo cursed. He picked up the Gatling gun and pulled the trigger.

The barrel is preheated. Bullets are fired.

It hit the Frankenstein monster. Black blood splattered out.

The Frankenstein monster didn't retreat. It climbed upwards, facing the bullets. Its limbs flailing wildly.

Old Li fired. The automatic rifle bullet hit the stitched monster's leg.

The Frankenstein's speed did not decrease.

It climbed the steps. A giant hand slapped at the dried tangerine peel.

A tremendous force surged through him. Chen Pi's knees buckled, and he half-knelt on the ground. The tower shield creaked.

"The power is too great." Chen Pi gritted his teeth.

Han Yingying stepped onto the edge of the tower shield and leaped up. Her straight blade slashed towards the Stitched Monster's mouth on its chest.

Two hands emerged from the Frankenstein's monster's chest and grabbed Han Yingying's blade.

Han Yingying pressed down hard. The blade sliced ​​open the stitched monster's hand. It got stuck in the bone.

The Frankenstein monster slapped Han Yingying with its other hand.

Lu Chen charged in from the side. His butterfly knife pierced the wrist of the hand. With a swift slash, he severed the tendons. The hand fell limply to its side.

Lin Qi watched from behind.

Lin Qi thought. Their teamwork was excellent. No verbal communication was needed.

Lin Qi drew his short sword and charged forward from the other side.

She used the wall as leverage to leap up, her twin blades piercing the side of the Frankenstein monster.

She didn't draw the knife. Instead, she gripped the hilt with both hands and her body slumped down.

The dagger slashed two long gashes across the Frankenstein's body. Black blood gushed out.

The stitched monster let out a muffled roar. Its mouth opened on its chest, spewing out a stream of green poisonous gas.

"Retreat." Han Yingying drew her sword and rolled backward.

Lu Chen and Lin Qi also retreated quickly.

Toxic gas filled the stairwell.

"Gas mask," Han Yingying said.

Six people put on masks. Lin Qi didn't. She covered her mouth and nose. Her face was pale.

Han Yingying took a spare mask out of her backpack and tossed it to Lin Qi.

Lin Qi caught it, put it on, glanced at Han Yingying, and said nothing.

The Frankenstein monster rampages through the poisonous gas.

"Jianguo. Armor-piercing shell," Han Yingying shouted.

Wang Jianguo switched to armor-piercing rounds. He aimed at the mouth on the Stitched Monster's chest. He fired.

The armor-piercing bullet pierced the Stitches' mouth, shattering the internal tissue.

The Frankenstein monster collapsed to the ground. Its body fell apart, turning into a pile of minced meat.
