The wealthy son-in-law of the female president

The laboratory is an absolutely closed environment. If the ventilation device is not turned on to allow the air in the room to circulate, the dense smoke will never escape.

The longer this time drags on, the worse it will be for the people in the smoke.

Su Ning gradually became afraid.

Suddenly, amidst the chaotic footsteps, she clearly heard a steady step, slowly walking towards the core area of ​​the laboratory, getting closer.

Su Ning was startled, and suddenly realized that the explosion was definitely man-made, and it couldn't be an experimental accident.

And the person walking towards the core of the laboratory is very likely to be the maker of the explosion.

Su Ning, who calmed down, noticed a detail. In the case of extremely low visibility, anyone's sight would be obstructed.

When walking, his footsteps should be chaotic and staggering. How could he be so calm and fast? He must have walked the route many times in advance.

Su Ning was so nervous that she clenched her fists tightly, her palms were already full of sweat, she tried her best to keep her breathing steady and not let her heart beat so fast.

Since the advent of the new purification technology, this was the second time she had encountered such danger.

As a little girl in her early twenties, it is already very good to be able to perform this way in the face of such danger.

Where is Yang Chen?
At this time, the appearance of Yang Chen appeared in Su Ning's mind, and now the only one he can rely on is him.

That steady and quick footsteps were getting closer and closer to the core area of ​​the laboratory. Su Ning's heart was already in her throat. She wanted to stop it, but she knew that she didn't have that ability.

At this critical moment, Yang Chen's voice suddenly rang in Su Ning's ears.

"Everyone, don't panic, keep quiet, and don't walk around at random. No one is allowed to leave the gate of the laboratory before finding out the situation!"

Yang Chen's voice was not far away, and he couldn't see the surrounding situation clearly, so he pushed away the people who wanted to escape one after another.

Yang Chen knew very well in his heart that once the door of the laboratory was opened, everyone would rush out, and the laboratory would be even more chaotic at that time.

And the perpetrator is very likely to take advantage of the situation and run away. It will be impossible for you to find out who is the instigator at that time.

In the thick smoke, everyone's sight was severely obstructed, but the penetration of the sound could still be maintained.

Of course, after Su Ning heard Yang Chen's voice, she relaxed her clenched fists slightly, and her rapid heartbeat gradually calmed down.

Fortunately, he is by my side!

Hearing Yang Chen's calm and composed command, the person walking towards the core area only paused slightly, and then continued to move forward.

Su Ning's fist clenched again.

The person who lurked into the laboratory and caused the explosion had a very precise calculation. He had already calculated that as long as there was chaos in the laboratory, there would definitely be people who were afraid of death.

As long as they can open the door of the laboratory, these guys who have not received special training will definitely cause great chaos.

Then he can take advantage of the chaos and calmly obtain the data of the new purification technology.

Then, taking advantage of the chaos, he pretended to be a panicked experimenter and left with everyone.

The abacus was very clever, but this time he met a calm person, Yang Chen, who disrupted his plan.

I don't know when, and I don't know how Yang Chen touched the gate in the thick fog. I only know that he guards the gate alone, and no one is allowed to go out.

Although Yang Chen has already done this, there are still some people who are greedy for life and afraid of death, and when their lives are threatened, they are unwilling to obey other people's orders.

Three of them squeezed towards the gate of the laboratory, Yang Chen reached out and grabbed two of them, and threw them back with all his strength.

Just as he was about to reach out to grab the third one, an imperceptible cold light bloomed in the palm of his hand.

A short, small but extremely sharp dagger stabbed towards Yang Chen's neck like a poisonous snake in the smoke.

The opponent's speed is really fast, and the attack method is extremely concealed.

When Yang Chen found out, the dagger had already cut his collar.

"Damn!"

Unable to fight him head-on, Yang Chen could only dodge, leaning back slightly, his neck was almost pierced by his dagger.

Vicious and vicious, one move kills!
Yang Chen preliminarily judged that the other party must have killed people frequently, otherwise he would not have such a vicious method.

Yang Chen turned around and came to the killer's side.

Just when Yang Chen was in a stance and was about to fight him, the killer put the dagger in his pocket like lightning, rushed towards the door of the laboratory, and shouted at the same time: "Everyone run together, that person wants to kill us Suffocate here, we can't listen to him, go!"

At this time, Yang Chen discovered that although he spoke Mandarin, his tone was a bit blunt, and he should be a foreigner.

Non-my family, its heart must be different!
Knowing that he is a foreigner, Yang Chen can strike without any scruples. With a flick of his wrist, a triangular army thorn magically appeared in Yang Chen's hand, emitting a black light under the thick fog.

After the killer's yell, the experimenters who had been hiding in the corner of the laboratory and didn't plan to escape in the chaos, all stood up at this moment and staggered towards the door.

At this moment, the killer rushed towards Yang Chen again, and the dagger in his hand appeared in the palm of his hand again.

The distance was less than two meters, and they were close in the blink of an eye.

Super expert!

One inch long, one inch strong, one inch short, one inch dangerous.

The Mitsubishi Army stab in Yang Chen's hand is much longer than the killer's dagger.

The killer is confident that his speed is very fast, no one can see his path clearly, but he was careless, Yang Chen was very keen to capture his trajectory.

Just when his dagger was less than a foot away from Yang Chen's throat, his dagger stopped moving.

Because the fist he was holding the dagger was pierced through by the triangular army stabbing with black light.

Yang Chen pulled out the three-edged army thorn, and the three-edged army thorn scattered a trail of blood in the air.

The killer could no longer hold the dagger, because a shocking transparent hole appeared in the palm of his hand.

At this moment, the killer already understood that this mission cannot be completed, and going back must be a dead end.

The only thing he can do now is to try his best to hold Yang Chen back, so that his companions have a chance to complete the task.

Before coming here, they had made a sophisticated plan, thinking that this mission would be easily accomplished.

But he never expected that a Yang Chen would appear out of nowhere, this little-known little guy, had a great tendency to turn the situation around.

Fortunately, there are two people who came out this time. One went to the core area to get the data of the new technology, and the other was responsible for secretly observing, creating chaos, and supporting them.
