On February 17, 200*, Japan's Daban secret base, which has been closed for more than 20 days since the last emergency. Now, no one in this world except Koizumi who escaped when the accident occurred, will know its existence again. But who would know that it is because of such a secret base that no one knows, which has caused panic in the next few years, and almost humans will perish.

At about nine o'clock that morning, in the base owner's control room full of darkness, the screen of a computer suddenly lit up, and the data on the screen kept beating. Then the computers in the entire control room were automatically turned on and started. Different data on each computer were constantly jumping. After a while, the lights in the control room were lit up, and a simulating voice in Japanese also rang out at the same time: "The inspection of each system of the base begins, the power system is normal, the air system is paralyzed, the base air index is negative 300%, which is fatal to the human body, the danger level is A, the heating system is normal, the No. 2 emergency plan is activated according to the instructions, and the base isolation is over.

Leaving the program, turning off the backup battery, starting the generator, each research room is powered on, starting the exhaust fan, and preparing to remove harmful gases at the base, starting the life detection scanner, conducting a full range of life scans on the base, and finding the survivors. "After more than ten minutes, the simulated human voice rang again, "The base power system is started normally, the backup battery has started to charge, the power of each research room has been turned on, the base exhaust system is started normally, and it is expected that it will take three minutes to restore the air to normal. The life detection scan has been scanned, and it is confirmed that there are no signs of life. The base air index is restored to normal, suitable for human life.

After the accident that day, Koizumi secretly took the only K-21 vaccine in order not to be exposed. While the base was about to be closed, he gave up all the researchers in the base, escaped from the secret base, and closed the only elevator leading to the ground of the base, allowing hundreds of researchers in the base to be poisoned to death by the poison gas released from the base's self-destruction program.

After leaving, Koizumi still thought that these things were done seamlessly. Unknowingly, after the accident, he wanted to cover up the conspiracy, but how could he have thought that at the beginning of the construction of this secret base, Yamamoto was also one of the members of the construction, and the main computer program of the base was designed by Yamamoto himself. When Yamamoto was designing this base security system, he might have been distrustful of Koizumi or something. When he was building the base, he didn't know why, but he always felt that he would be in the future.

It seemed like something happened, so in order to prevent someone from going against him in the future, Yamamoto deliberately left a safe backup system when designing the system. Therefore, the base that Koizumi left behind was considered destroyed and permanently closed was turned on again after more than 20 days of closing. With the opening of the main program, the lights in each research room in the base began to light up one by one. The secret base that had been dark for a long time instantly turned out particularly bright under the lights.

At this time, in the laboratory where Yamamoto and Koizumi were experimenting, the walls around were covered with blood, and the human organs and limbs on the floor were all terrifying and disgusting. However, there was a naked monster and a few wearing researchers' costumes. Some had no hands, some had a big hole in their stomachs, and some had only half of their heads left. The monster kept making a sound of "点!点!" in the laboratory.

It stopped and wandered left and right. At this time, maybe the air was restored to normal. One of the naked monsters slowly walked to the door of the laboratory and sniffed it with his nose, then screamed twice, and then began to hit the door hard. With its slamming, the door in the laboratory made a series of sounds. After the monster hit for a while, maybe it saw that the door was not damaged, so it screamed at the surrounding monsters after a few times.

The monster immediately surrounded the door and started to hit the door constantly. The sound of hitting the door was still ringing, but the door was not damaged at all. But at this moment, a monster that had lost both hands hit the door and lost its balance and was opened by the door. As a result, it hit the door's switch. The door opened automatically with a "puff!" sound. The door opened, and the naked man who was commanding other monsters to hit the door.

When the monster saw that the monster in front of him touched something red, the door opened automatically. It looked at the switch that was touched by the monster and slowly walked over. It had long nails on its hand, touched the red switch on it, and saw that the door automatically closed again. So it pressed it a few times again. The door opened and closed again, and then opened again. The monster pressed and looked at it. After several consecutive times, it lost interest and walked out of the laboratory and came to the aisle.

Because when the self-destruction program was started, the only elevator in the base was stopped on the ground when Koizumi evacuated and closed. Therefore, other researchers in the laboratory failed to escape from the base in time. Finally, the poison gas released by the self-destruction program set by the base was poisoned and fell into every corner of the base. Several monsters walked out of the laboratory and saw the corpses lying everywhere. They were hungry and seemed to see the abundant food, and they rushed up and bitten it.

In a moment, the organs and limbs on the corpse were carrying blood that was about to dry up. They were bitten by several monsters with their mouths and hands. Several monsters kept tearing each other and enjoyed the blood of human corpses and the rich food composed of organs. They bit the corpses one by one.

But at this moment, something unexpected happened to Koizumi. In an instant, the corpses bitten by the monsters in the base were also resurrected. They climbed up from the ground, followed the monsters in front, and began to look for other corpses and bite the corpses. Gradually, the entire base became particularly bloody and terrifying, with various human organs and limbs scattered everywhere. At the same time, the K-21 virus began to spread through these monsters and corpses. In half a day, the entire secret base was filled with many monsters wandering everywhere. In this way, a virus that was enough to destroy humans began to spread in this secret research institute.

Three days later, at the drain outlet of the base, two mice were holding two pieces of meat and crawling slowly from the drain outlet. After the long drain outlet, the two mice finally dragged the meat into their nest. Six little mice in the rat nest saw two adult mice dragging the meat back to the nest, and they were all hungry and screaming. The two adult mice dropped a large piece of meat into the little mice, while the two adult mice ate around the other piece of meat.

The two pieces of meat were quickly wiped out by a nest of mice. The mice that had a full meal were thinking of having a good sleep. At this time, the six little mice in the nest began to suck menstruation all over the body, and then the bodies began to grow rapidly. Then the two adult mice also began to experience the process experienced by the young mice. After about five minutes, the eight mice in the rat's nest stopped growing. The originally spacious rat nest was as big as a cat by these eight people.

The little mice were squeezed without any space. The growing mice became very bad. They are now very hungry because of their growth. They are hungry because of their crowding in their nests and they started to fight each other violently. After a while, the mice may be too hungry and began to crawl out of the hole. However, due to the mutation, the original passages are no longer suitable for their entry and exit, so the crazy rats
