Fresh air was injected into the testing room, and for a short time, the testing room suddenly became silent. In the loud volume of the intercom equipment, I couldn't hear a trace of sound in the room, and it seemed that the heartbeat of the experimenters in the room was gone.

But more than ten minutes later......

The people outside heard another sound coming from the testing chamber, first with a rapid wheezing sound, followed by the screams of the experimenters. At this time, the experimenters seemed to be awakened sleeping devils, and sharp screams, mournful wails, and miserable cries were intertwined in an instant.

At this time, even the people outside seemed to have reached the verge of collapse, and some security guards even covered their ears, not daring to listen to these sounds. In the end, Dr. Z couldn't take it anymore, he turned on the microphone on the intercom and began to shout inside.

"Listen, I'm Dr. Z. I can feel your pain, so I've decided to end this trial right away. Now I've pumped fresh air into the room. You don't have to worry, when the gas is replaced, I will release you, and give you the rest of the reward you deserve, and give you back your freedom. Dr. Z said into the microphone at great risk.

After that, everyone heard the screams in the test room, and Dr. Z shouted three more times, and at this time, it had been nearly half an hour since the fresh air was replaced inside, but at this moment, something unexpected happened......

Suddenly a high-pitched voice came from inside the testing room, and the force of the voice seemed to tear the vocal cords apart, and the voice shouted, "We don't want air, we don't want air......"

Immediately after that, several voices came out of the room at the same time, which was also heartbreaking.

"We're going to gas ......"

"Gas us ......"

"Let's not sleep......"

"We don't want to be free ......"

Accompanied by terrifying sounds, there was also the sound of smashing in the test room, and the sound of banging on the door from time to time. The situation has reached a point where it is difficult to end.

"Doctor, what now?" Huang Qiang asked.

Dr. Z lowered his head and thought for a long time, and finally after he sighed, he ordered Huang Qiang to open the valve of Nikolai gas to replace the fresh air, and still maximize the emission of Nikolai gas.

With the introduction of Nikolai gas, the sound in the test room gradually became quieter, and after another half an hour, the room was finally quiet, and there was no sound at all.

Dr. Z knew that the current group of experimenters were like addicts, they had adapted to Nikolai gas and had developed a resistance to normal air.

If it continues like this, Dr. Z can't predict how the next experiments will go.

That night, two people went to the general manager's office on the second floor of the office building.

Dr. Z, who went first, gave him a serious warning on the other end of the computer after he finished reporting what had happened today, and he told Dr. Z that this was the last time he would not listen to instructions and make decisions on his own. If there is a next time, he knows the consequences.

After listening to this, Dr. Z did not dare to argue again, he turned off his computer and went back to the underground testing ground. But at this time, Dr. Z's heart was very turbulent, and he was ready to do another thing to disobey the order.

Later, there was a person who came here, and this person was Huang Qiang. He didn't come here to report, but to ask for an exit.

After listening to his request, the computer also gave him a quick reply. It means that you can agree, but if you want Huang Qiang to hold on for another week, he can leave after a week and get the corresponding reward, Huang Qiang is very happy after hearing it.

Three more days passed, during which the four people in room B also entered a state of self-enclosure, and they also sealed the inside of the glass wall, but they did not pay attention to the monitoring equipment and did not destroy it.

The testing room has been unusually quiet these days, with only occasional chewing sounds being heard inside. There were no more screams and thrashing, and if it weren't for the occasional chewing sound that proved they were eating, the people outside would have thought the experimenters inside were dead.

The subject who came in later went into a state of madness, as the second chamber he was in was a separate test room. There was no indication that he was to be monitored, so Dr. Z had the iron door closed and the man alone inside to continue his madness.

On the evening of the third day, Professor Z finally received a happy order, which was to stop the experiment, and quickly escort the experimenter to evacuate, and the car was waiting at the other exit, that is, outside the mine.

After a while, Lisa arrived, carrying an incubator on her back, which was used to hold the concentrated Nikolai gas that Dr. Z had been preparing for the past few days.

Professor Z first carefully placed eight miniature hydraulic bottles in the incubator brought by Lisa, and told her to be careful, this is an important research result in the past few days, and it is extremely dangerous, once it leaks a little, if it is inhaled by the human body, the consequences are unimaginable.

After handing over the experiment, the next step was to transfer the experimenter, which is now a problem. Because what Dr. Z is afraid in his heart is that he doesn't know what has become of the experimenters, especially the experimenters in the A test room?

Eventually, Dr. Z decided to move the subjects in Room B first, as they were now relatively safe.

Dr. Z didn't turn off the Nikolai gas first, because he was afraid of the scene before it turned off. So he asked Huang Qiang to take people, all wearing gas masks, guns and corsets, and then went to room B to escort the experimenters.

Dr. Z and Lisa had been standing in the surveillance room watching, and they were also worried about what would happen suddenly.

Dr. Z first calls out to Room B, telling them that the trial is over and that he is taking them out now. After saying this a few times, Dr. Z saw that the experimenters in the room didn't react much, but that's it, he had to go in and bring them out.

Huang Qiang had the courage to open the door of room B. When they entered, the four subjects were still quiet, and then the security personnel quickly tied them to their corsets, and then pressed them out of the second chamber. Then he quickly passed through the corridor to the secret passage under the mine shaft.

Here, four experimenters were transported to it via a transmission device. After that, Lin Dapeng, who had been waiting on it for a long time, took the four experimenters onto a special box truck, and the first transport truck drove away.

The first wave of transfer tasks was successfully completed, but Dr. Z, along with Huang Qiang and the others below, knew that the real difficulty was still to come, that is, to transfer the people in the A test room.

Dr. Z shouted to Test Room A several times in the same way, but there was still no movement in the room, which made everyone present feel inexplicably chilled, and they all had a premonition that something worse was about to happen.

Dr. Z first asked Huang Qiang to reduce the amount of Nikolai gas in the room, because the concentration of gas in the room was too large at this time, and the person who entered it was very likely to inhale the gas even if he was wearing a gas mask.

As the minutes ticked by, everyone's eyes were glued to the hallway of Test Room A on the computer monitor, even though they couldn't see what was going on inside. And everyone pricked up their ears to listen, but there was no sound at the other end of the intercom, and the silence was terrifying.

"Let's get moving!" Dr. Z gave the order.

Huang Qiang led people to the door of room A, although they were all wearing gas masks, they also smelled a foul smell coming from the room. Because gas masks can only filter gases, but they still can't resist the smell.

Huang Qiang took out the key and inserted it into the keyhole, with the rotation of the key, the door lock was opened, after Huang Qiang pulled out the key, he pushed the door with his hand......
