Because he always remembered what Lu Feng said just now, and the reason why he didn't kill him was because he was still useful.
And his only role was to help Lu Feng open the door locks to enter the laboratory.
Now, they have reached the last door.
As long as this door is opened, even if the person in charge loses his role, will Lu Feng still let him continue to live?
Therefore, the person in charge did not dare to open the door directly.
"Do you think you are qualified to negotiate terms with me?"
Lu Feng blew out a puff of smoke without even looking at the person in charge.
"I..."
Upon hearing this, the person in charge fell silent for a moment.
How could he be qualified to negotiate terms with Lu Feng?
Now his life is in Lu Feng's hands. Lu Feng can kill him whenever he wants. What can he do?
"open."
Lu Feng pointed to the door in front of him with his chin.
"If you don't kill me, I can still tell you many things, many things about the institute."
The person in charge walked forward and spoke cautiously.
He wanted to use these things to get Lu Feng to spare his life.
"Oh? What else do you know?"
Lu Feng asked deliberately showing interest.
"I know a lot, including many things outside of the institute."
"As long as you don't kill me, I will tell you all this."
Seeing Lu Feng's interest, the person in charge immediately spoke quickly.
"Okay, okay."
"As long as you are obedient, everything will be easy to talk about. Now open the door first."
Lu Feng nodded slightly and pointed at the door again.
"Okay, I'll open it right now."
The person in charge nodded. Since he had already negotiated with Lu Feng, he naturally no longer had any worries.
"Crack."
The door lock was unlocked and the door was slowly pushed open.
"Pfft."
However, just when the door was pushed halfway open, the person in charge felt a weight behind him, and then he saw the tip of a dagger sticking out from his chest.
It was obvious that someone stabbed his body from behind.
The person in charge's eyes widened, and with disbelief in his eyes, he slowly turned his head and looked behind him.
Sure enough, it was Lu Feng who made the move.
But he didn't understand. He had just negotiated with Lu Feng, and he still had many secrets to tell Lu Feng so that Lu Feng wouldn't kill him, but why would Lu Feng go back on his word?
Doesn't Lu Feng not want to know those secrets?
"Japan is a small country, what secrets can you have?"
"It's just that I killed a few more people."
Lu Feng snorted, pulled out his dagger and swung it across.
"Pfft."
His throat was sealed with a knife, and the body of the person in charge slowly fell to the ground. The blood instantly stained a large area of the ground red.
Lu Feng didn't even look at him, and walked straight inside.
As for the secret mentioned by the person in charge, Lu Feng really didn't care.
Because he never took Japan seriously from beginning to end, he just regarded Japan as a despicable villain who only used insidious means.
Lu Feng didn't regard them as opponents in the same rank at all, so why would he care about what secrets they had?
Just like a tiger, does it care about the secrets of a group of mice?
Therefore, Lu Feng was not interested at all in the secrets mentioned by the person in charge.
And if Lu Feng lets this person in charge live, he will definitely find ways to contact the outside world, which will be troublesome for Lu Feng.
It's better to kill him directly to avoid any trouble later.
Looking at the last door in front of him, Lu Feng stretched out his hand to push it open and walked straight in.
The laboratory is very large. In addition to the hall where Lu Feng walked in, there are several closed rooms made of completely transparent glass around it.
There are about twenty workers in the entire laboratory, and they all look very busy.
Each of them wears a white coat, just like a doctor, but they are essentially different from doctors.
Because doctors treat illnesses and save lives, but the things that people in the laboratory study can make life worse than death, and even bring disaster to many people.
Therefore, even if they put on doctors' white coats, it cannot change their identity as demons.
"They all say that I, Lu Feng, am as ruthless as a devil, so what are you?"
"When I kill you demons, my hands are stained with demon blood. How can I be a demon?"
Lu Feng murmured to himself, then gently closed the door and stepped forward slowly.
I originally thought that my sudden intrusion would frighten everyone in the research institute into panic.
But what Lu Feng didn't expect was that the people in the laboratory were just busy and didn't even look at him.
Even if someone saw him, they quickly looked away and continued busy with what they were doing.
Lu Feng frowned slightly, feeling extremely unhappy.
It feels like you go to the bank with a weapon and prepare to rob, but both the customers and the staff are busy doing their own thing without even looking at you. Who can bear this kind of frustration?
"I said..."
Just as Lu Feng was about to speak, a man in a white coat reached out and grabbed him.
"Go, help me send this sample to Laboratory No. 3."
As the man in the white coat spoke, he stuffed something directly into Lu Feng's hand.
"court death."
Lu Feng's eyes were stunned, and the next second he suddenly slapped his palm out.
"Crack!"
That powerful slap made an extremely clear sound, and the man in the white coat was also slapped away by Lu Feng.
"Bang!"
"Wow!"
"Plop."
The man in the white coat flew backwards and hit many bottles and jars. Countless glass fragments mixed with liquids of various colors were scattered on the ground.
It was only then that the laboratory staff discovered Lu Feng's existence.
"Baga! What are you doing?"
A man in a white coat walked towards this side angrily.
Judging from his different clothes from the others, he must be the manager here.
"I'm asking you, what are you doing?"
Seeing that Lu Feng was silent, the man in the white coat shouted again.
"roll."
Lu Feng snorted coldly, raised his hand and slapped him again.
"Crack!"
After this slap, the whole body of the man in the white coat flew up like the man just now.
You must know that Lu Feng is now a respected warrior, and his strength is ridiculously powerful, far beyond the scope of ordinary people.
Even if he doesn't use his internal energy and just uses physical strength, it is definitely not something that ordinary people can withstand. He can kill someone with just one slap.
The reason why these two people were not slapped to death was because Lu Feng deliberately suppressed his power.
"You, who are you and what are you going to do?"
Seeing how fierce Lu Feng was, everyone else became much more honest.
They are all a group of powerless researchers. Faced with such a terrifying existence as Lu Feng, how can they dare to challenge him?
"In ten seconds, everyone will line up and stand here."
"Otherwise, die."
Lu Feng slowly stretched out his hand and pointed at the open space in front of him.
