Screams from a room on the first floor of the lab alarmed the scientists in the same building. One by one, they put down what they were doing and ran towards the room where the screams were heard. Among them were quite a few armed men, who rushed ahead of the others.

A modest wind blew through the corridor, and the armed men who had run to the front suddenly fell to the ground. There was an opening in their necks, and blood was pouring out of it. The scientists who followed had just seen the fallen armed men, but before they could figure out what was happening, the wind was already blowing past them. In each of them, a long gash appeared.

At the end of the corridor, Shi Tao's figure appeared there. After glancing at the fallen person, Shi Tao burrowed into the other rooms without stopping. All the scientific researchers or armed men he saw along the way died under the short knife in his hand.

Before entering the laboratory, Shi Tao didn't want to do this. Although he knew that there would be bloodshed in this rescue, he did not think about killing all the staff members he saw. But when the lights came on and he saw an experiment going on in a room. Shi Tao changed his mind. The knife in his hand was no longer under his control.

Shi Tao still can't forget how he felt when he was lying on the test bench, his chest cavity was opened, and the dying mutant told him a happy word. At that point, he could no longer control himself.

Above the fifth floor of the laboratory, Wu Tian, Meng Hao and Xiao Yu entered through the windows on the fifth floor. They were the last to enter the lab. After entering, they didn't find anything on the fifth floor, they only heard a chaotic sound from downstairs, and walked towards the fourth floor. On the fourth floor, they found the bodies of some men in white coats. On the third floor, they found more corpses, as well as some mutants.

When they reached the second floor, they found more bodies in white coats and uniforms, as well as a man standing in the middle of the hallway, slitting the throat of a white coat with a scalpel. That person was none other than Han Feng. From the fourth floor to the second floor, most of the scientific researchers died in the hands of Han Feng. As long as they saw it, the scalpel floating next to Han Feng would fly out, ruthlessly taking their lives.

"Captain, what are you doing?" After Meng Hao saw Han Feng standing among the many corpses, he immediately understood how these people died. Seeing that Han Feng had killed so many people, he asked with some incomprehension.

Han Feng turned his head, his face was cold, and he said expressionlessly, "Go to the room and see what they have done, and you will understand what I am doing." ”

With that, he walked downstairs. In the corridor, I saw Shi Tao who was about to come up. Shi Tao nodded at Han Feng, then turned around and returned to the first floor.

After Meng Hao and the three of them entered the laboratory, they didn't search room by room, of course they wouldn't understand why Han Feng was so angry. After they visited a few rooms under the guidance of the other mutants, they finally understood why Han Feng did this.

At this time, outside the laboratory building, it was already surrounded by soldiers. Since the power outage, the soldiers outside have lost contact with the laboratory. When the power was restored, all the communications equipment was destroyed, and they had no way to contact the people in the lab. There is no way to enter through the closed door of the laboratory. When screams came from the lab, they all realized that something was wrong in the lab.

What is in the laboratory, of course these soldiers guarding the laboratory know. Every test subject inside is very dangerous. Even if one escapes, it can cause a disaster. Now the real lab is locked down. And from inside came a faint scream. These soldiers did not dare to forcibly enter the laboratory, so they could only surround it. Do your best to restore the communication equipment, and pray that things inside don't get too bad.

When Han Feng walked to the first floor, the entire part of the laboratory floor had been cleaned up. No scientific researchers or armed personnel survived. All died at the hands of mutants.

Even if Han Feng and Shi Tao didn't kill these people, those mutants who had regained their freedom would not let them go. A few staff members who were originally knocked unconscious by Han Feng when he first entered the laboratory died tragically at the hands of mutants who had regained their freedom.

"Hold the above-ground part and don't let anyone in. Shi Tao and Wu Tian went underground with me. Wait until we've dealt with the entire lab building, and then we'll deal with the people outside. ”

When the mutants were all gathered on the first floor, Han Feng gave an order. Han Feng's tone did not allow others to refute, and he didn't care if these mutants listened to him or not. At this moment, he was truly like a leader, giving orders to everyone. Instead of talking to other people about how to do it, as you used to. Unconsciously, Han Feng's mood changed. The way things are viewed has changed. In particular, the way of dealing with life has changed.

Without refuting Han Feng's order, many of them had seen Han Feng's strength. The vast majority of these people are red-eyed mutants, and only a few have superpowers. Except for the people Han Feng originally brought, even if they went together, they might not be able to deal with Han Feng. This is also the capital that Han Feng dares to order them.

Due to the failure of all equipment, the road to the underground has been blocked. A thick iron gate blocked in front of him, making it impossible for Han Feng to pass through.

"Who can break through this iron door?" Han Feng asked among the mutants.

"I can." A yellow-eyed mutant with a pale face and many scars on his body walked out.

Han Feng and the others stepped aside. The man walked up to the iron door and pressed his hand on it. The surface of the iron gate suddenly began to melt, and a large amount of molten iron trickled down the door. It didn't take long for a large hole to appear in the thick iron door.

"If the body can, then you come with us." After moving enough on the iron gate for one person to pass, Han Feng said to the person who had melted the iron gate.

"Go, of course." The man said resolutely.

Han Feng didn't say much, and passed through the iron gate first. He could see the indelible hatred in the man's eyes. He couldn't imagine what kind of thing had happened to these people here. But he knew that no one could stop these people from taking revenge. Even death can't stop them.

Through the long passage, Han Feng and the others finally reached the basement floor. The door to the basement floor was ajar, and the moment Han Feng pushed the door open, the muzzle of the black hole was pointed at him. When the owner of the muzzle saw Han Feng's appearance clearly, he suddenly pulled the trigger one by one.

The bullets were surging, but Han Feng did not panic in the slightest and still walked forward. The bullets all stopped in front of him. As he stepped through the door, several scalpels shot out, heading straight for the guards who were firing at him.

No one could stop Han Feng's footsteps, and all the armed personnel who appeared began to shoot at Han Feng almost the moment they saw Han Feng and his party. But they had only one result, and that was to die under Han Feng's knife.

Killed some of the guys who got in the way. Han Feng and the others dispersed, looking for possible survivors on the basement floor. As a result, only three mutants with unknown abilities were found in the basement floor.

After settling them, Han Feng led the people to continue down. There are more mutants on the second basement level, and there are more injuries. Some of them have been seriously injured and are on the verge of death. Even if Han Feng rescues him, I'm afraid he won't live long.

With no living mouth left, Han Feng continued to go down. He could already see that the main work of this laboratory was carried out underground. He didn't even dare to go underground, for fear of seeing something even more terrible. But he couldn't stop, he had to find all the mutants. Even if it's a corpse.

When they reached the third basement floor, Han Feng and the others did not meet with resistance. The basement three floors were quiet. After entering for a while, I saw some corpses lying on the ground, as well as two mutants who had just escaped.

Originally, Han Feng thought that these two mutants who had escaped from the predicament had killed the staff on the third floor of the basement. But just as he was about to ask, he saw a white coat fly out of a room and hit the wall. A red figure rushed up and snapped the neck of the white coat.

After twisting the neck of the white coat, the man covered in blood turned his head to look at Han Feng and the others. His face was so red that it was almost impossible to distinguish what he looked like, except for a pair of bright blue eyes.

"Summer rain."

"Han Feng, I didn't expect it to be you."
