Night gradually fell, at more than ten o'clock in the evening, in a secret research institute in Okumacho, Toei, a man wearing a scientific research uniform and a mask on his face, took the opportunity of all the scientific researchers to rest, quietly came to the laboratory, he overtook the button in his hand, pointed the iron cage at the laboratory door, and then swiped the work card on the recognizer, and quickly entered a set of passwords.

"Click!"

A clear sound suddenly sounded, the door of the laboratory slowly opened, and the man standing outside the door of the laboratory, through the glass of the laboratory, looked at the monkeys in the laboratory, and saw that the monkeys did not enter the cage, and then walked to the cage and tried to introduce the monkeys into the cage.

"Boom!"

When the man walked to the back of the cage and tried to introduce the monkey into the cage, he only heard a loud noise, and the cage that was originally placed in front of the laboratory door instantly hit the man's body, and the powerful impact force made the man feel a sharp pain in his chest, and then he lost consciousness.

The loud sound of the cage hitting the wall immediately alarmed the researchers who had been resting in the research institute, and just when these researchers realized that something was wrong, the monkey trapped in the laboratory rushed out of the laboratory, jumped over the unconscious man, and bit the man's neck and sucked the blood in the man's vein.

"Baga! The experimental subject has escaped from the laboratory!" The scientific researcher in charge of the duty saw the monkey lying on the man's body sucking blood, and a frightened expression appeared on his face, and he hurriedly and loudly warned the scientific researchers in the research institute, and did not forget to ring the alarm in the scientific research institute.

The scientist's shout immediately alarmed the monkey who was sucking blood, and at the moment when the scientist pressed the alarm, the monkey jumped up from the man, instantly threw the scientist to the ground, opened his bloody mouth and bit the scientist's neck.

Just as the monkey threw the scientific researcher to the ground and sucked the blood, the man who was sucked dry of blood by the monkey and died, his body suddenly twitched violently, and then slowly got up from the ground and staggered towards the outside of the laboratory.

The piercing alarm sound instantly spread throughout the research institute, and those scientific researchers who were awakened by the alarm sound heard the piercing alarm and got up one after another to find out, only to see the scene of monkeys sucking human blood.

"Ahh

Seeing this scene, all the scientific researchers were stunned, but when everyone was stunned, the corpse that had been sucked dry by the monkey suddenly pounced on the body of a female scientific researcher, and directly bit off a piece of skin from the other party's face, and the intense pain made the female scientific researcher let out a miserable scream.

The screams of the female researchers brought all the researchers back to reality from their stunned at once, and at the same time attracted the attention of the monkeys.

The cry of the female researcher not only woke up the other researchers, but also attracted the attention of the monkey, and when the monkey saw these panicked and fleeing researchers, he immediately remembered the torture it had suffered during this time, and the hatred made the monkey's eyes extremely red, and immediately threw away the corpses in his hands and threw himself at these researchers.

Just as the monkey chased after the researchers, the corpse that was thrown to the ground by the monkey first had a violent convulsion, and then slowly got up from the ground and chased after the scientists who fled for their lives.

When these scientific researchers tried to use the elevator of the scientific research institute to escape from the scientific research institute, they did not realize that when the alarm sounded, the elevator and all the passages leaving the scientific research institute were automatically closed.

Seeing that there was no response to the elevator, Kitazawa remembered that as soon as the alarm sounded, all exits of the institute would be automatically closed, unless someone lifted the alarm from outside, otherwise they would be trapped in the institute, hearing the continuous screams from afar, Kitazawa clearly knew that there was only a dead end to stay here now, and he had to find a place to hide immediately, realizing this, he immediately rushed in the direction of the living quarters.

The screams continued to sound in the institute, and after about an hour, the screams gradually subsided, and the entire institute except for the monkeys who had escaped the net, the rest were the living corpses that had been sucked dry by the monkeys.

At about six o'clock in the morning, the telephone at Ono's house rang suddenly, and Ono, who was asleep, heard the phone ringing, stretched out his hand in a daze, picked up the phone on the bedside table, and asked in a daze, "Moses!

"Oh no, the siren suddenly sounded at the institute last night, and we have lost contact with the institute. As soon as Ono's words fell, a middle-aged man nervously reported on the phone.

Ono, who was sleeping in a daze, heard the report of his subordinates, and the sleepiness that was originally enveloping him disappeared without a trace in an instant, and the whole person sat up from the bed at once, and asked with a shocked face: "What did you say? Lost contact with the research institute? When did this happen?"

"Section Chief Ono, this is what happened at eleven o'clock last night, and after we received an alert from the research institute, we tried to get in touch with the research institute, but we were never able to get in touch with the research institute. The other party heard Ono's angry question, and hurriedly made a report to Ono about the situation he currently had.

"Baga!!

In the face of Ono's questioning, the middle-aged man felt very weak, because he was idle last night, so he drank some wine, so he didn't notice the alarm at all, until he went to the bathroom in the early morning, he found that the alarm in the institute went off, and when he contacted the institute, the communication on the research institute had been completely interrupted.

However, the middle-aged man would not be stupid to take the responsibility on himself, he heard Ono's questioning, and replied against his will: "Section Chief Ono! Since I found out that the alarm light of the research institute was turned on, I have been trying to get in touch with the research institute, but I have never been able to get in touch, and then when I think of reporting to you, it is already more than three o'clock in the morning." ”
