"Stamping the Sky Light Slash!!!"

Several sword lights passed through the body of the massacre A2. As the last sword fell, the body of the massacre A2 instantly exploded, turning into countless pieces of corpses and splashing everywhere...

Once Luo Tianhuan made a single pass in the Crazy Laboratory with Nightmare Level Difficulty alone, now he can still make a single pass once again, and it is faster...

"Boom!!!" Luo Tianhuan kicked the already damaged automatic door and kicked the automatic door out directly...

After the opened channel, Luo Tianhuan's strength instantly exploded and rushed to the next area...

"You look very anxious!" David Black's voice answered in the long corridor...

"That's of course, because I have to save that person... This is agreed..." Luo Tianhuan waved the laser sword in his hand, slashed the machine gun battery that suddenly appeared on the wall, constantly avoiding the attack of the passage trap, and his speed still did not decrease at all. He rushed to the end of the corridor at that amazing speed...

"It seems that you do have some strength, and maybe you can also go to the end of this base, but for Valkyrie Laboratory, your strength is not enough!"

"Of course I know... but I can't look back anymore... You are the same, aren't you?" Luo Tianhuan smiled faintly and looked at the large number of zombies hidden in the darkness ahead...

"Indeed, we can't look back! Say your name! I still admire you more!"

"I...my name is Mengfanbubble..."

"Dream Bubble? This name... I feel like I have heard it somewhere... It feels so familiar..."

"David Black, one day...you will think of this name!"

"Ho huh huh!!!"

Luo Tianhuan held a laser sword in his hand and rushed towards the zombies in the dark... The rotten blood sprayed on Luo Tianhuan's face...

"Maybe! Maybe one day...I will think of you, a familiar stranger..."

Because of the game system, David Black has always existed in this crazy lab copy. As the players enter, David Black appears again and again. With the encounter with the black demon, David Black dies again and again. Every time he meets different players, and then forgets again and again. Although he is one of the top leaders of Valkyrie's laboratory, he will always be reincarnated here.

"Ho huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh

A large group of zombie dogs pounced on them, but the moment they approached Luo Tianhuan, they were all dismembered by the laser sword in Luo Tianhuan's hand...

Luo Tianhuan is different from himself when he was the first to guide the Crazy Laboratory. Now he is stronger...

In the darkness, the laser sword in his hand was constantly wielding again and again. The laser sword that kept wielding in the dark seemed to become the only light of this darkness...

Zombies kept roaring and roaring in the darkness. Gradually, the sound became weaker and weaker until it completely disappeared... When the light of the laser sword illuminated Luo Tianhuan around him, there were only the remaining limbs covered with the ground, and Luo Tianhuan, who was dyed into a bloody man...

"When a person strives to change everything, in the process, he also changes himself...I can see that your heart is occupied by killing and anger..."

"There is nothing to do... Do you ask me to show mercy to a group of monsters?" Luo Tianhuan stepped on the remains of the corpse and went to the next area...

...

In the control room of Crazy Laboratory, David Black was watching Luo Tianhuan, who was slaughtering experimental subjects in the experimental area through surveillance. The experimental subjects in this laboratory could not stop Luo Tianhuan's footsteps at all. Those experimental subjects that seemed powerful in people's eyes were as simple as cutting melons and vegetables in front of Luo Tianhuan...

"Maybe he can solve the black demon! Basel, this is the price you deceived me!" David Black smiled faintly, stood up from his seat, picked up the laser rifle he placed in the corner and walked out...

The alienated brain and the giant cannibal flower are both bosses who once gave Luo Tianhuan a headache and even almost failed. However, for Luo Tianhuan's Luo Tianhuan, they can basically be taken away within one minute.

When Luo Tianhuan finished solving the giant man-eating flower and stepped into the final experimental site, Luo Tianhuan finally saw the familiar figure... David Black...

"Do you want this?" David Black took out a blue potion from his pocket, looked at Luo Tianhuan and smiled faintly. According to the information reported by the system, Luo Tianhuan knew that it was the antidote for the grRT virus...

"Yes, I need that thing to save someone!"

"To save someone, you should know that this antidote for grRT virus can only save ordinary people infected with grRT virus, and the infected person cannot be infected for more than three hours, otherwise even if there is an antidote, he will be completely powerless to make things happen! I can give you this antidote, but you must answer me a question and help me do something!"

"Tell me!"

"First of all, why do you know my name and my affairs?" David Black stared at Luo Tianhuan's eyes. Although Luo Tianhuan did not say it clearly, he was sure that Luo Tianhuan knew everything about him very well...

"I am a person who once fought side by side with you, even though you have forgotten me... Although the time for fighting side by side is less than ten minutes..."

"Is that true?!" David Black raised the laser rifle in his hand and pointed it at Luo Tianhuan, his eyes becoming very cold...

"The last time I appeared on the battlefield, it was already twenty years ago. You in front of me looked too young! Why did you say that I fought side by side with you!" David Black pulled the trigger at Luo Tianhuan, and several lasers attacked Luo Tianhuan...

The moment David Black pulled the trigger, Luo Tianhuan quickly waved the laser sword in his hand. The laser collided with Luo Tianhuan's laser sword, and a series of sparks burst out...

Luo Tianhuan suddenly appeared in front of David Black using his breakthrough skill, and the latter was also a battle-hardened figure. He immediately pulled the grenade in his hand and threw it at Luo Tianhuan...

"boom!!!"

The grenade exploded, and Luo Tianhuan's sword was already on David Black's neck. The moment the grenade was thrown at Luo Tianhuan, it was directly knocked away by Luo Tianhuan...

"Your sword is very fast! There is a shadow of the Apocalypse Fleet, but not all!" Even when Luo Tianhuan put the sword on his neck, David Black was very calm... Or he believed that Luo Tianhuan would not kill him, otherwise he would have died when he saw the antidote for the grt virus in his hand...
