"Mike, how long should we go in this direction?" Neo asked with annoyance. His bullet was limited in number, so killing off every monster with his bullet was certainly out of question.

Mike shrugged. "Don't complain so much. You can kill them with one-shoot kill, right?"

Neo's face darkened. "It didn't mean that I like to stay in the place with these monsters crowding around me!"

"The building is already within the sight. You just have to be a bit more patient."

"That's good."

Mike nodded his head when he felt sudden danger. His body tensed up and he instinctively pulled the monster near him to block him on the right side. Sound of flesh tearing followed soon after that.

BANG! BANG!

Neo tried to shoot the person who attacked them, but his shot missed completely. He frowned when Mike held his arm.

"Randy," Mike shouted. "You've grown faster."

From behind the monsters, Randy stepped out. He arched his eyebrows. "Your senses have become extremely keen for you to spot me in this place."

"Naturally," Mike replied.

Randy watched the two people in front of him. Although he knew that he had grown stronger because of the medicine that Ferdinand gave him, these two were not easy to handle.

He raised his twin daggers. "I have told you that our next meeting won't be that simple. It seems, we have to finish our fight in this place right now."

"I won't give you any handicap," Mike readied his stance. "Give me all you got, Randy."

"Of course!"

Laboratory

Professor Taren listened to the report from Vena with annoyance. She used the communication device to tell him that they were under attack.

"Like I say, it's not my problem!"

Vena stayed unmoving as she placed the device in front of her mouth. "Sir Ferdinand wants you to finish the experiment as soon as possible and retreat from this place."

"Where's that man?"

"Sir Ferdinand is in seclusion to take the medicine that you give to him."

Professor Taren knew that it would take several minutes before Ferdinand could consume the content of the medicine into his body. During that time, this place would be without him.

He eyed the laboratory that he loved so much. He truly didn't wish to leave this place.

"Fine, I'll leave after administering the last dose of medicine to that girl," Professor Taren gave his final answer.

He slammed the phone on the table and looked at his assistant and numerous doctors in the laboratory. They gathered here because the lab has a secret passage to get out, so they were waiting for Professor Taren to give them the key.

He looked at his assistant. "Bring that girl here."

The doctor's face turned into despair in that instant. They were struggling so hard to take her into this place yesterday. Many of them were wounded hard and still unable to recover in the room next door.

The head assistant accepted the order. He walked out of the inner room towards the outer layer. In that place, numerous doctors were waiting for his order. He glanced around his subordinates. "Who's the one that managed to make that girl drink the medicine yesterday?"

"It's this man." a doctor immediately pointed to the man beside him.

The head assistant looked at the doctor. "What's your name?"

"Shiro."

"Bring that girl here and I'll take you to the inner room," the head assistant ordered.

Shiro eyed the man curiously. "Can you truly bring me inside?"

The head assistant nodded his head. "My card can be used to open the door for the inner lab. Don't worry. I'll heed to my words."

"I see. That's good."

"Now that you understand…"

BANG! BANG! BANG! BANG! BANG!

Series of gunshots sounded in the room. Before they could react to the sudden attack, most of them had fallen to the ground. One shoot was all he needed to kill them.

"You!" The leader was stunned to see the gun on Shiro's hand. "Why? Who?"

BANG!

Shiro killed the man with ease. There were more than 50 doctors in this room, but within seconds, he had killed them all. His gaze was cold and unfeeling, totally different with his usual kind and playful gaze as a doctor.

"I forgot to introduce myself properly," Shiro chuckled. He unloaded his gun and reloaded it back. "My real name is indeed Shiro, but I have my secondary name 'Shin' in Black Street."

The rest of the doctors were looking at Shiro with horror filled their face. They knew that they wouldn't be able to get out of this place alive. Before long, Shiro had sent them all to their death door.

"Now, the card," Shiro headed to the leader and picked up the card that this man had.

He walked to the door and used the card to swipe. The door unlocked and a smile appeared on Shiro's lips. He had waited for this day for a long time.

Stepping into the laboratory, he saw that Professor Taren was not alone. There were numerous people around him.

"Have you taken that girl…"

BANG! BANG! BANG!

It took Shiro split seconds to kill the surrounding doctors. They were unable to react in time as Shiro killed them all without any mercy. They all participated in the experiment to be human with potential and created those monsters.

Professor Taren was struck with panic as he turned around. He looked at Shiro with a stunned expression. A gun was directed towards his forehead as Shiro stood not far from him. His face was expressionless as he stared at the professor in front of him.

"Good day, Professor Taren, we meet again," Shiro greeted.

Professor Taren looked at Shiro with confusion. Shiro's face was not familiar to him. "Have me met before?"

Shiro arched his eyebrows. What should he expect from this man? He treated many people around him like he treated trash. They would never be treated as human, so this man would never remember anyone whom he did experiment on.

"Let me refresh your memory," Shiro leaned on the table behind him. "Shiro Servo, the child of Servo Family Head. You took me in and destroyed my family before taking my cousin when you realize that she has more power than me. But around 9 years ago, the two of them disappeared without any trace."

Professor Taren's eyes widened as he stared at the young man before him. In this laboratory, only three people have ever gotten out. He eyed the man before him with a smirk on his face.

"Ah, so you're that brat. I have only managed to awaken your talent for marksmanship when you ran away. It seems that you haven't gone far away, Shiro."

Shiro looked at the man before him with disgust. This was the man who caused him to experience numerous painful memories in this place when he was very young.

"Today will be the day of your death," Shiro aimed at the professor, ready to pull the trigger.
