(PS: Thanks to the book friend Purple Blood Demon King for his reward. In addition, the time limit of the task has been changed.)

“Accept or cancel the task?”

There is no doubt that he must have accepted the task. Chen Ke's actions this time were mainly for the generator and energy value. At this time, the task was triggered as he expected, so how could he cancel it?

As soon as the thought came to mind, he accepted the task.

“You have accepted the mission.”

“Current air pollution source 4/4.”

"The fifteen-minute countdown begins!"

Are there four sources of air pollution?

This is not fun!

You should know that the task time limit is only fifteen minutes. Who knows whether the four air pollution sources are all in the same place? If they are not in the same place, fifteen minutes will be really compact. What's more, if those air pollution sources are the culprits that cause the air in front of you to be dim and rotten in the soil.

Then, Chen Ke is absolutely sure that with the closed secret room conditions of the freezer, the interior has long been filled with deadly polluted air!

It's really a big problem to get inside.

"It smells so smelly, so bad." The door of the freezer has not been opened, but you can still smell the extremely pungent smell. Chen Ran said, pinching his nose.

Jiang Qing was even more unbearable. She shouted in horror: "I... suddenly felt a little paralyzed in my hands and feet!"

"It must be caused by these yellow gases. Don't get too close to Kumen, don't inhale too much polluting gas!" Xu Shi hurriedly covered her mouth and nose and retreated from Kumen for a few steps.

Chen Ke's eyes narrowed, and he held the circular wheel switch outside the warehouse door with both hands, rotated it hard, and said vigilantly: "Should you hold your breath, I'm going to open the door!"

When the few people heard this, they held their breath.

Chen Ke was not out of the box. He calmed down and opened the cold storage door with a cautious expression.

"Sher—!"

As soon as the warehouse gate was opened, a stream of extremely cold air came out, and then countless green and yellow corrupt gases emerged.

In this gas, Chen Ke could feel his skin allergies and stinging!

At this time, the scene in the cold storage room fell into everyone's eyes.

In the cold storage room, there are many sarcoma mines on the walls, floors, and ceilings on both sides, with blood and minced meat on the ground. In the middle, there is a strangely shaped human-shaped infected body.

It has two huge lungs, but it grows on the back and looks closer to humans. Its blood is black.

Standing in the cold storage, he only released poison gas. Seeing that Chen Ke and others had no tendency to attack, he just spit out blue and yellow poison gas from his lungs.

"There are three bullets left in the pistol. I wonder if the pistol has any effect on this thing."

Chen Ke did not act rashly, but stretched his right arm straight in a line, holding the pistol at the palm of his tail, and his eyes gaze from his arm to the muzzle to the gas-infected body, and his index finger was pulled.

Bang!

A yellow-orange bullet flew away from the rifle of the gun and swirled towards the poisonous gas-infected body.

Puchi!

A blood flower splashed out from the body of the infected body, and the poisonous gas became thicker and thicker, without any injury.

With just one shot, Chen Ke knew that even if he fired all two bullets in his hand, it would not cause much damage to the poisonous gas-infected body.

Fortunately, this poisonous gas infected body seems to only know how to create poisonous gas, but it does not have the desire to attack or attack methods.

It seems that this task is a bit simple?

But in fact, it was not. Chen Ke quickly realized the difficulty of this task. He had been holding his breath in this poisonous gas for more than half a minute. Generally speaking, the limit for a normal person to hold his breath is about one minute.

If the surrounding environment is quiet and prohibited, some great people may be able to extend it to 2 minutes.

But in this situation, he has ambushed everywhere in crisis, and consumes much more oxygen than normal.

Even if his body strengthens to 7 points of physical fitness, he still needs to breathe, and the limit of holding his breath is only four to five minutes at most.

Deficiency of oxygen will cause the human brain to rapidly decline in judgment and thinking ability, not to mention sarcoma mines in cold storage. Therefore, this task is difficult and not simple at all.

Chen Ke couldn't speak, so he gestured with his hands, asking Chen Ran and the other two to retreat, wait for him outside, and walked into the cold storage room with lithium electronics knife.

The difficulty of the task lies in these sarcoma mines. They are the point that delays time and hinders his progress. We must find a way to walk past the sarcoma mine and approach the toxic gas maker, and then cut off the toxic gas maker with one knife.

This is a plan that Chen Ke has drawn up.

However, it is not an easy thing to move forward from these sarcomas, although his brain rotates very quickly, he can't think of a good way for a while.

There are only two bullets in the pistol, and at most they can detonate two sarcoma mines.

There are seven or eight sarcoma mines in this cold storage, which is just a drop in the bucket.

Because he held his breath, Chen Ke felt that time was passing slowly and difficult, with blue and yellow colors everywhere around him. The first sarcoma mine was on the ceiling. He looked up and saw that the sarcoma kept stirring frequency, and the ceiling dripped from time to time.

The oxygen stored in the lungs is being consumed, so you can't go wild like this.

Chen Ke made up his mind that if he had a way to solve the sarcoma, the only way was speed!

Cut it before it detonates, and at the same time retract the knife when it detonates.

This is too difficult!

Chen Ke was not sure, but he wanted to try it, not just stand and let the oxygen in his body consume all the oxygen.

He was the kind of person who had the perseverance to execute once he made up his mind and began to act.

Chen Ke did not use a knife to detonate the sarcoma on the ceiling, but instead used a gun to detonate it. There are two reasons: one is that the ceiling is too high, and the violent beating will accelerate the loss of oxygen. The other is that he may not be able to cut the sarcoma on the ceiling.

Therefore, the first sarcoma was detonated by a pistol.

As for the second sarcoma mine, it was grown on the floor. Chen Ke raised his knife, held his mind, and devoted all his attention to the knife. Suddenly, Gauss's arm became blurred!

The next moment, a blue and white knife line appeared.

Crack, a few pools of yellow liquid splashed out!

The sarcoma separates from the flesh wall, erupts and explodes!

Although Chen Ke took back the knife when the sarcoma exploded, his hands were still affected by a slight slight impact and his flesh and blood was blooming!

This consumed one-fifth of his oxygen reserves!

But he became relaxed unexpectedly.

This knife was just an experimental knife. Despite his injuries, he was confident that the next knife would be faster and more proficient.

Chen Ke continued to move forward. He removed all the sarcoma on the floor and the wall and exploded. He encountered a sarcoma on the ceiling and was detonated by him with a bullet.

As time goes by, the amount of oxygen in his body becomes thinner and thinner.

Chen Ke made a knife, drew it into a line, and then put it away.

After repeating this action, he finally approached the poison gas maker. He raised his knife and sped forward. The thunder and lightning arc gathered in the dark scene, and the arc and lightning surged!

The body of the poison gas maker cracked into two petals, and the blood rain immediately sprayed and shot out.
