Time passed minute by minute, Han Tianyu had been waiting quietly, and the other party seemed to be surprisingly patient.

"Stepping on the ......" At this time, footsteps came out in the distance!

"Dididi......" A green mark appeared on Han Tianyu's helmet display, which was a hint that his teammates were nearby.

"And survivors?!" Han Tianyu was overjoyed, it seemed that he was not the only one who survived the crash.

The footsteps of "stomping and st......omping" are getting closer and closer, and the green dots on the small map in the helmet monitor are getting closer and closer, and the other party has obviously discovered Han Tianyu's existence, and it can be heard from the footsteps that he has changed from the previous slow progress to a trot.

A few seconds later, Han Tianyu saw a soldier in power armor running in at the entrance of the valley, this guy was the NPC sitting on Han Tianyu's left side when the plane had not crashed.

"Stomp ......" The NPC ran towards Han Tianyu quickly, obviously wanting to join his companions.

"Be careful!" Han Tianyu reminded loudly, but it was already too late!

"Whoosh!" A white shadow flashed from the side, and the NP who ran towards Han Tianyu was defenseless, and was instantly pounced on by the white shadow!

There is no doubt that this white shadow is the infected female researcher that Han Tianyu found before, her speed is extremely fast, and after knocking down the NPC soldier, a pair of extremely sharp claws slammed into the throat of that NPC!

Blood burst out, and the NPC received a boxed lunch in an instant!

"Suck and slip...... Sucking ......" The mutated female researcher frantically licked the blood of the NPC soldiers, but she stopped to forage for food and gave Han Tianyu a chance to attack!

"Pedal ......" Han Tianyu pounced on the female researcher, and after two steps, he even turned on the jetpack.

Under the strong thrust of the jetpack, Han Tianyu's speed in a straight line was pushed to the extreme, and in just an instant, he came to the side of the female researcher, and at this time, the female researcher was frantically sucking the blood of NPC soldiers.

Although this mutated female researcher has a certain amount of intelligence, after the mutation, she is obviously dominated by instinct, and she is not as sane as the liaison before, so after seeing the blood, her bloodthirsty instinct is stimulated, and at this time, she only has the fiery blood of the NPC soldier in her eyes, and she simply ignores Han Tianyu who is attacking behind her!

"Click...... In the process of running, Han Tianyu put away the dagger, then took down pub325 and opened the insurance!

Because pub325 itself is in engineering mode, and it is also loaded with energy magazines, Han Tianyu does not need to be too cumbersome to operate, and when he came to the back of the female researcher, the muzzle of the gun had already sprayed a red laser.

With a wave ......of his hand, Han Tianyu split the female researcher into pieces, but although the mutated female researcher died, the NPC soldier couldn't survive either.

At this time, although the NPC soldier's body was still twitching, he had lost too much blood, and Han Tianyu did not have blood transfusion equipment by his side, so this guy was hopeless at this time......

In order to prevent this soldier from mutating, Han Tianyu dug a deep pit, buried him, and pressed a boulder on it to ensure that even if this guy mutated, he could only be locked up underground.

Then Han Tianyu took out an identity card on the female researcher's body.

"Olicia, Ph.D. in Biology, Deputy Director of the Kershville Laboratory......" Han Tianyu silently read the information on the ID card.

Putting away the identity card, Han Tianyu came to the place where the female researcher appeared, and then searched carefully nearby, and soon, he found the entrance to the laboratory, a hidden isolation door!

"Didi ......" swiped Olisia's identity card on the identifier of the isolation door, and the isolation door opened automatically.

Looking out of the door to the laboratory inside the mountain, there was only a deep tunnel, and nothing else could be seen, and the tunnel was very clean and very quiet, and the silence was terrifying......

"Stomp on the ......" Han Tianyu walked in, the metal boots of the power armor made contact with the ground in the laboratory, making rhythmic footsteps, which were particularly clear in the silent laboratory.

As Han Tianyu continued to advance, he soon came to the end of the corridor, where there was an intersection, according to the prompt of the signs, the left was to the experimental area, and the right was the administrative area.

"The source of the mutation should be in the experimental area." Han Tianyu muttered, and then walked to the left, but he didn't notice that at the end of the corridor on the right, a pair of blood-red eyes were watching him.

"Stepping on the ......" With the sound of footsteps, Han Tianyu quickly came to the experimental area, and before he could enter the scope of the core laboratory, he saw a lot of corpses lying on the ground.

These corpses were all wearing white coats, and they looked like they should be researchers in the laboratory, but at this time they were all dead, and I don't know if they died from the infection of the virus, or were killed by mutants, but they did not mutate because of this, it seems that this mutation is not 100% triggered after being infected, this virus is about 100% deadly, but only a few people will mutate.

Bypassing these corpses, Han Tianyu came to the core experimental area, where there were more corpses, in addition to those researchers in white coats, there were also many corpses in hospital gowns.

"These guys are test subjects, aren't they?" Han Tianyu secretly guessed in his heart.

However, the corpses here are different from the corpses outside, a large part of the corpses outside have external injuries, judging from the wounds, they should have been attacked to death by mutants, and these corpses in the core test area are almost intact, it seems that these people should have died from the virus in the early stage of the spread of the virus, and a few people mutated after death, and then these mutants rushed out of the core test area and attacked other uninfected people.

"It looks like the original mutation should have originated here......" Han Tianyu nodded secretly, and then he began to search carefully.

Soon, Han Tianyu found a handheld computer on a test bench, and found some relevant information in this handheld computer, according to which he finally understood the beginning and end of some things.

It turns out that this laboratory belongs to a mercenary organization, but in Han Tianyu's opinion, this game is officially led after all, so in the background setting, this illegal project must be deducted from the head of the mercenary organization, otherwise they won't slap themselves in the face?

Experiments on genetically enhanced warriors are being secretly carried out here, but unfortunately, the experiment went awry, and the virus used to strengthen the body caused uncontrollable mutations in humans, and finally the catastrophe was formed......
