Just when the team leader was about to move back, a bulge suddenly appeared in the middle of the alloy door. The dull banging sound in the room even penetrated the 10 cm thick alloy door. There were more and more bulges, and there was a sound from the edge of the door.

There was a heart-wrenching "creak" sound and countless cracks appeared on the edge of the alloy door. At the moment of the accident, everyone's weapons were aimed at the door. The security personnel near the door quickly retreated, and soon there was a huge blast.

The alloy door, which had been severely deformed in the explosion, was thrown out by a huge force. It hit the metal wall on the opposite side and bounced back, scraping countless sparks on the metal ground. The door was smashed out with a huge force and rushed out of the room.

Suddenly a huge monster appeared. When he saw this creature for the first time, the only thought in the captain's mind was: he is dead this time!

The huge creature is a fully recovered mutant zombie or an invader. It has devoured a lot of high-energy "food" in the containment area, and its body has successfully undergone a mutation upgrade. It stands close to five meters in height.

, the whole body is covered with dark red steel-like muscles, the sharp blades on the fingers reach 30 centimeters, and many sharp bone spurs grow on the elbows, knees, back, heels, etc., and the chest, head, and lower body are covered with dark red

A thumb-thick exoskeleton grew outside the muscles and was connected to the body. The exoskeleton almost completely covered the entire face. The exposed brain was protected by the exoskeleton again, but the mouth was still exposed, but the extended fangs proved that

The defense here is definitely not bad!

The team leader had fought against the monster when it first attacked the base. At that time, the monster could only hold up to about four meters and had only muscle tissue on its body. The gun could barely have an effect on it, but when he saw the guy in front of him,

The captain's heart was filled with shock. Heavy gunshots rang out, and the bullets fired continuously hit the monster's muscle tissue with difficulty even breaking through the defense. If they hit the bones, sparks would fly everywhere, leaving only a trace on the bones.

If you look carefully at the shallow pit, you will find that the small pit where the bullet was just shot has been restored to the naked eye!

The monster that was targeted by fire did not fight back, and even squatted on the ground with his hands (claws) on the ground, not caring about the bullets hitting his body. Twenty seconds later, the gunfire gradually became sparse and stopped, and all the security team members stopped firing in unison. It felt like

After the body was not attacked, it stuck out its tongue and slowly shook it in front of it. At this time, the security team had replaced the new magazine and aimed at it again. Although they knew that the gun had no effect on the monster, they used the gun anyway.

Pointing at the target always brings some comfort to oneself. The monster's tongue suddenly stopped in the air, and then quickly returned to its mouth. The huge body seemed to be stunned for a moment, and the head suddenly rotated 180 degrees, covering the bones.

His eyes were fixed on one direction: the storage room!

No matter who is being stared at by a five-meter monster, it will be frightening. After the security team saw its movements, intensive gunshots rang out again, but the monster still ignored everyone, and its huge torso turned in the direction and used its feet hard.

A pillar of the ground quickly rushed out with the "crunch" of the deformation of the alloy floor. Everything in front of it was knocked away and wailed all over the place in an instant. A few guys who were unlucky enough to be standing in front of the monster were knocked out before they even landed.

With no chance to survive, the remaining security personnel did not have time to deal with the injured teammates. They reported the battle situation here to their superiors and immediately chased after them. Regardless of whether their weapons could cause damage to the monsters, it was their task to defend the fourth floor. As long as they could still

You must complete the mission while you are alive!

In the outer room of the storage room, the metal floor is still slowly being corroded, but the area has only shrunk to about two meters. If you look further, you will find that the space on the lower level is extremely large, filled with countless liquids filled with scarlet transparent pipes, and I don’t know where they are connected.

, the pungent smell in the air in the room became stronger and stronger. The girl stared at the gap on the third floor. The mechanical gloves attached to her hands had slowly moved to the forearms and turned into a pair of translucent wrist guards.

A blue energy shield faintly emerged, and suddenly an apple-sized metal ball fell from the gap. Seeing that the surface of the metal ball was covered with physical collision sensors the size of a thumb cap, the girl's face changed slightly when she saw this thing, and her body changed as quickly as a cheetah.

He rushed over, and before the metal ball hit the ground, he suddenly raised his right hand and swung upward. The energy shield attached to her wrist instantly transformed into a traction ray and threw the metal ball back to the gap in the ceiling. The girl had stopped while throwing the ball.

The forward body stepped hard on the alloy floor and returned to Anna at a faster speed than before. He squatted down and stretched out five sharp blades from the fingertips of his left hand and penetrated deeply into the floor in front of Anna. The energy of his right arm

The shield was also activated to its maximum at the same time, building an energy barrier in front of her that was enough to cover the two of them. The clear crash of the metal ball sounded in the quiet room, and the light from the gap in the ceiling was strangely distorted.

A three-meter-sized micro artificial black hole appeared at the location of the explosion. All matter in the vicinity of the black hole was absorbed and completely annihilated visible to the naked eye. Although the black hole only lasted less than two seconds, it was huge when it collapsed.

The shock wave of energy plowed through the entire room. There was only one hole in the room leading to the ground. Along the corroded hole, it caused serious damage to each layer above (the fourth layer used a stronger secondary super alloy, and the third layer used a stronger secondary super alloy.

The above defense strength was not enough to resist the power of this energy shock wave). The security team who were searching on the upper level and some researchers in the safety isolation room were affected and suffered heavy casualties instantly.

The girl also felt uncomfortable. Her body appeared in a burst of electricity. The energy barrier blocked most of the damage for her. If she was the only one, she could completely block it. However, in order to protect the Anna girl behind her, the defense range was expanded, resulting in insufficient energy supply.

, the shield generator persisted until it was overloaded and destroyed, but the girl did not suffer much damage. It can be seen that the protective suit she was wearing was also quite powerful. She removed the shield generator with current flowing from her arm, but be careful.

But Li kept staring at the ceiling, her intuition telling her that the guy was not dead, the sense of crisis still existed, and another more uneasy feeling slowly appeared outside the door.

After sensing the crisis, the masked man slowly moved away from the entrance to the fourth underground floor. After retreating to a range of tens of meters, he threw his most destructive mechanical creation at the entrance of the hole. After throwing it, he opened his protective shield to

The biggest, who knew that the thing was thrown back again? The moment he saw the thing, he was frightened to death. Fortunately, the place where it was thrown back was far enough away from him, and he was able to hold on under the energy shield and sophisticated equipment.

After a terrible attack, 70% of the energy of the shield generator was consumed, all the external electronic weapons on his body were overloaded, and the terminal in the mask needed to be restarted. These were all within his acceptance range, but the reaction speed of the enemy below

It gave him the idea of ​​​​retreating. The unknown contractor was about the same strength as him, but the opponent should be a fighting type. He did not have the advantage in close combat. The external equipment all over his body was seriously damaged. After the terminal was restarted, all the weapons on his body would be lost.

It takes at least five minutes to replace it. During this period, he can be said to be absolutely vulnerable, and a greater sense of crisis gradually arises. He is sure that if he comes into contact with it, it will bring him a greater sense of crisis.

Thing, it must be you who is killed!

Anna slowly looked into her eyes, and the pain in her body made her gasp in pain. Although she was protected by the girl and was not in danger of being exposed to the energy impact, the injuries were unavoidable. Now she has multiple bruises all over her body and a fractured shoulder blade on her left arm.

, her hair was messy and her face was stained with blood. After her vision returned to normal, she seemed to be frightened by the situation in front of her. The whole room was in a mess. There was a huge hole in the ceiling in front of her. There were faint sounds of explosions and burning above. The whole room was in a mess.

The walls and floors were full of scratches, and the air was filled with a disgusting smell. A girl wearing strange tights squatted in front of her, and the corner where the two of them were was the weakest place in the room. Anna
Chapter completed!
