"Close the door!" the director of the biochemical center, the white man with a big nose, his eyes flushed, hissed and almost vomited all the air in his lungs, frightening several boys behind him to rush to the protective safety door.

The first young experimenter who touched the door hesitated for half a second, then opened the door and rushed out. As soon as he returned, he pulled up the 15 cm thick stainless steel protective door, and then quickly turned the manual switch of the safety gate on the door to lock the door!

Through the thick glass on the door, the people inside who had not had time to escape desperately pulled the door handle, but could no longer open the door of life. They jumped and jumped, shouted to the man outside like crazy, crying and begged him to open the door. He held the steel door handle with both hands in amazement, hesitated and hesitated again and again

Soon, the green smoke began to diffuse in the biochemical laboratory. The light green fog dissipated in the air, but everyone felt fear. The white director had rushed to the glass cabinet by the wall, grabbed a gas mask and put it on his face, and the rest were quickly robbed.

The director wearing the gas mask hurriedly turned on the computer again, called out the first-class virus protection program, and released the alarm level to "the most critical"!

"Breathe! Breathe! Hurry up..." the director of the laboratory shouted under his opponent across the gas mask. An experimenter ran to the wall and smashed the red alarm button on the wall with his elbow.

Soon, on the top of the laboratory, the circular wind tunnel began to work, and four huge exhaust fans rotated to dry the air in the laboratory in the shortest time.

With the strong updraft, some people's hair floated.

"Come on, the third step!" the white director hissed. The third protection procedure was opened, the interwoven fire water pipes on the roof were started, and the diluted disinfectant drenched everyone like rain.

What should be done was done. Everyone stood in the same place with gas masks on. They didn't know what to do for a moment. They looked at each other with two round black hole eye masks across the gas area, and a trace of fear rose in their hearts.

They know what they are studying, and they know that such protective measures may just make up for the lost, but they still hope to have a chance to survive

Slowly, the exhaust fan stopped, the indoor ventilation work had been completed, and the spraying of disinfectant stopped, leaving only sporadic residues dripping knee deep in water.

"We're fine! Great! Ha ha... What a thrill!" a young boy suddenly laughed.

Everyone seemed to feel a kind of comfort from his words immediately. They clapped hands with each other. God bless

"Ah!" a man suddenly grabbed his throat and his eyes burst out like being pinched by a strange hand. Then everyone in the laboratory had serious breathing difficulties.

They frantically tore off their gas masks and tore their clothes to pieces. The great pain and itching forced them to scratch every inch of their skin. Some people poured into the disinfectant, and their skin was corroded by the disinfectant, resulting in large areas of redness and swelling immediately

In a twinkling of an eye, the laboratory, which had just become an active atmosphere, became a hell on earth. The power-off protection program was turned on, leaving only a red alarm light whistling and rotating, alternately refreshing the expression of pain and despair on people's faces. Someone ran to the door recklessly and hit the metal protective door with his head, breaking his head and blood and breaking his skull.

"Alarm! Alarm... The virus of the Biochemical Department leaked, please evacuate the experimental area! Alarm, alarm!" the cold and ruthless female voice announced the message in the air without emotion.

The doors of more than a dozen laboratories in the periphery were opened, and thousands of experimental employees swarmed out like the hospital after work and rushed towards the door of the experimental building in a panic.

When people rushed to the gate, they found that several exits had been locked by electronic sensors, and no one could go away!

So someone took down the metal chair used for rest on the side and smashed the door like crazy. The light sound knocked everyone's eardrum. There was a sharp cry of women, and a sour smell in the air was spreading.

It's still sunny outside. People walking in the street not far away don't notice anything at all. The design of the experimental building is absolutely closed. In case of any accident, even the sound can't be heard.

"Lv Fang!" when Thor stormed in from the outside, LV Fang was sitting comfortably on his sofa tasting a cup of coffee.

"Come on! Come on! Something's wrong with the experimental building! The virus has leaked, all the physical firewalls have been started, and all the people in it can't get out!" Thor shouted.

LV Fang trembled. The coffee cup fell on the crystal floor of the office and broke to pieces. He also flustered and touched his crutch and stood up: "where's Ke Ke? Is she in there?"

"Nonsense! She lives there!" Thor complained angrily. "I told you it's not safe there. If something happens, I can't run away! Should I?"

"Let's go, let's go!" Lv Fang was almost trotting with his crutch. He didn't have his usual old and steady appearance. He rushed out of the door while talking, and his stiff body barely matched his body's movements.

In the monitoring center outside the experimental building, LV Fang and Raytheon call out real-time monitoring images. Hundreds of cameras in the experimental building monitor the movements in every corner. It can be seen clearly here.

All the people fell to the ground, like a battlefield full of corpses after a battle.

"Center, look at the center!" Thor's voice urged anxiously, and his eyes showed an extremely anxious look.

LV Fang glanced at him and silently adjusted out the picture. In the thin gray-green smoke, all the people in the laboratory of the biochemical department were dead. The body was floating on the water more than half a meter deep, and the shape was strange.

Looking inside, the material laboratory is empty, there is no one, only some cold equipment and 3D printers are still working alone.

The experimental building is a circular structure with dozens of divisions on the outer edge, which are responsible for the experimental work of summarizing data. The middle layer is the biochemical department. Due to the need of confidentiality, each layered employee can't walk around each other, and the space between departments is relatively closed.

The next link is the new material experimental area, which is an important area in the charge of Wang Yanke. The center of the whole experimental building is Tianyin Super Brain laboratory, where Wang Yanke established his own super brain to summarize and calculate experimental data.

At the moment, there are only two people left in the central laboratory, Wang Yanke and a senior engineer of Tianyin computer maintenance, an engineering man wearing glasses and a guy with freckles on his face. Because he works with a mouse all year round, his five fingers of his right hand are always unconsciously pinched together, so we gave him a nickname called mouse.

"We should go and see what's going on outside, maybe..." Wang Yanke suggested carefully.

The mouse looked out at the window of the closed door, shook his head and died. We don't know what the leakage source is. We can't take risks. Wait, wait for the rescue team to come
