Mental power 23/30.

"BGM" can't be used for the time being, and the Fire Escape Hao Fireball Technique alone may not be able to completely kill the tracker, not to mention that there are many β virus monsters nearby.

"Smack-"

The tracker suddenly reached out and grabbed a β monster running past him, and the tentacles on his arm instantly wrapped around the head of the β monster, and after the explosion, a sarcoma-shaped head appeared, with a tentacle several meters long at the top of the head.

β the speed of the monster and the flexible attack of the tentacles, this is several times stronger than the zombie that the tracked person turns into a sarcoma-head.

Gu Cheng, Carlos, and Tyrell could only rely on fire suppression to prevent β monsters from approaching, while retreating towards the end of the passage.

When everyone retreated to the entrance at the end, Gu Cheng knew that the security door alone could not stop the tracker, so he said directly to Tyrrell: "Blow up the entrance!" ”

Previously, because of the sudden intrusion of the giant crocodile, a C4 explosive and medicine were saved, Gu Cheng asked Tyrrell to place the C4** at the front of the entrance, and after the explosion collapsed the entrance, and then closed the security door, which was regarded as a "double guarantee".

But everyone knew that the monster's ability would not be able to stop the tracker for too long, so they hurried to the inner experimental area to continue looking for their way.

Claire placed Shirley in a bed in an infirmary in the inner lab area, where the group began to search for a vaccine to treat herry. Gu Cheng's heart was very heavy, he didn't know whether to tell Claire that there was only a T-virus vaccine here, and Shirley was infected with the G virus.

Just as he hesitated, Claire suddenly shouted in surprise: "Gu Cheng! I've found news about the vaccine, come and see! ”

When Gu Cheng and Carlos heard this, they immediately walked up to Claire and looked at the experimental file in her hand.

The place of antigens and adjuvants in vaccine synthesis

Dr. Nathaniel Budd

Principal Investigator, Spencer Memorial Hospital

In order to synthesize vaccines with very high efficiency, both antigens and adjuvants are indispensable. Antigens can elicit an immune response, and adjuvants can enhance the effect of the reaction, thereby accelerating antibody production. A sample of both components can create an effective base vaccine.

With our patented equipment to process this base vaccine, it is easy to produce large quantities of effective vaccines. In addition, the vaccine made using my modified antigen and adjuvant samples has an unprecedented increase in antibody production, and the yield is 1,000 times higher than that of a vaccine made from conventional materials. This allows the vaccine not only to be preventive, but even to eliminate viral infection.

……

Looking at the above content, Claire said excitedly: "As long as you find a sample of the two ingredients and a machine to make the vaccine, Shirley will be saved!" ”

Gu Cheng didn't know if this vaccine had an effect on Shirley, but he was currently trapped in the experimental area, so he could only try it first, even if it could delay the onset of the virus on Shirley.

So, the three of them began to split up to find samples and machines to make vaccines.

The experimental area is large and well demarcated.

Gu Cheng walked through an area full of various infected culture tanks, and came to the control room at the end, through the control room, he could see that because the power supply equipment here was not affected, those culture tanks continued to supply sedatives, so the infected people inside were still asleep.

Gu Cheng couldn't help but wonder, if there was a problem with the power supply system before they came here, would they have to face hordes of lickers, hunters, tyrant T-103 and other biochemical weapons, not to mention the protagonist group, even if he came, he would be killed in seconds.

Gu Cheng was about to leave the control room, when suddenly there was a soft "snap", and the lights in the entire cultivation area dimmed.

A mechanized female voice rang out over the loudspeaker above: "Warning-warning-power system compromised, 001-009 area power supply system has been stopped, 006 area cultivation system suspended for x3119 sedation and replaced with manual operation." ”

Gu Cheng: ??? Are you meowing me?

At this time, Carlos also rushed over: "Gu Cheng, are you here?" There was an explosion in the experimental area just now, I don't know what the situation is, Tyrrell has already rushed over to check! ”

Gu Cheng shouted at Carlos in front of the console, "I'm here!" Hemp eggs! This Nima will not have a problem sooner or later, as soon as we get here, we will have problems, and I don't know if the system is cheating us! The sedative injection problem here must be solved now, or we'll have to deal with a whole bunch of monsters out there! ”

Carlos ran to the console and saw Gu Cheng hurriedly manipulating the instruments on the console, and immediately asked, "Can you manipulate these things?" ”

"No, it won't. But it's nothing more than manually choosing the type and dose of sedatives to be injected.,Anyway, I don't have to pay for killing these monsters.,Just choose the maximum dose for all.。 ”

Carlos:...... It feels so reasonable.

Under Gu Cheng's frantic operation, a large amount of X3119 sedative was injected into the culture tank.

"The power supply system must be restored as soon as possible." Gu Cheng said.

Carlos nodded, followed Gu Cheng out of the cultivation trough area, and when he walked through the corridor, a man in a white coat fell there at the end of the corner.

Gu Cheng saw that the man was holding an A4 paper in his hand, walked over and squatted down to the right, pulled out the paper from the corpse's hand and looked at it, and saw that it was written crookedly-

Worst-case scenario...... Or did it happen...... The T-virus somehow escaped. I had to follow Dr. Bard's instructions and make a lot of vaccines.

I have prepared a set of antigen medium for T virus. Now I just need to combine them with adjuvants to improve its efficacy, and I should be able to make enough vaccines to save all the surviving citizens.

Adjuvant samples are kept in the incubation laboratory. Subject is already wandering the halls...... But I'd better find a way to get some samples while the medium matures......

If I can't come back, go ahead and complete the synthesis procedure. It's important to find a way to stop the outbreak. Having single-handedly caused this horrific event, this is the only thing we can do.

But be careful of the subjects wandering through the halls of the testing area, as they possess very powerful regenerative abilities, and some of them have advanced evolutionary individuals that are not inferior to the speed of lickers. My team refers to these subjects as "Pale Head Prototype and β Type", respectively. They appear regularly and constantly, but the exact cause is still unknown. The rate at which these pale heads regenerate is so incredible that conventional weapons can hardly pose a threat to them. In the event of any system failure at the facility, we will not be able to effectively defend ourselves.

For this reason, I have requested that a batch of high-firepower weapons be assigned to the arsenal to ensure that we can quickly eradicate the threat in the event of an emergency.

……

"Ahh

But Gu Cheng had already taken precautions, his left arm was directly blocked forward, and the AMG-13 mechanical fist glove was against the zombie's neck and pushed him to the wall, and with Victor in his right hand in his eyebrow, it was a sudden burst, directly blasting off his head.

As Jill puts it, Gu Cheng is an "expert" at dealing with infected people.

Gu Cheng stood up and said to Carlos: "The adjuvant is in the incubation laboratory, but there are a lot of β monsters wandering there, to ensure safety, you can only go to the arsenal to get heavy firepower weapons first." According to the plan diagram at the entrance to the experimental area, the arsenal is below the experimental area. ”

"We're ......"

"Da Da Da-"

As soon as Carlos spoke, he heard a burst of gunfire in Shirley's medical area.

"Let's go!" Gu Cheng hurriedly returned to the medical area with Carlos, only to see that Tyrell was covering the retreat of Claire, who was holding Shirley, and a pale-skinned β-type monster was sprinting back and forth between the hall and the laboratory, constantly attacking Tyrell.

Gu Cheng and Carlos immediately joined the battle, although the three guns could suppress the pale head β, its recovery speed was too fast, and it couldn't kill him with the damage of Victor and the assault foot and gun.

This is also why when Gu Cheng found a large number of pale skulls at the entrance β he would choose to use the Fire Escape Hao Fireball Technique to blow them up and buy time to close the door.

The pale-headed β seemed to find that the weapon firepower in the hands of Gu Cheng and the three of them could suppress it, so he rushed towards Claire, who did not attack it, Gu Cheng would give it a chance, and tore off a g4 hand and thunder from the waist of Carlos beside him, blocking it in front of Claire, and the palm with the AMG-13 mechanical fist directly pinched the neck of the pale head β, and pressed the hand and thunder directly into its mouth with his right hand.

"Boom-"

The hand and thunder exploded, directly blowing off half of the pale head β, but Gu Cheng was also affected by the explosion and was injured by the impact of "-50".

[Kill the Pale Skull β gain 100 XP. 】

The Pale Head β an elite monster like the Gamma Hunter, but the former is much more difficult to deal with than the latter, at least Gu Cheng will not choose it as a "leveling object".

"Thank you...... You, are you alright? Claire looked at Gu Cheng worriedly wiping the blood on her face, she knew that Gu Cheng had been trying her best to cover her and Shirley, and every time the β monster rushed up, Gu Cheng always bore the brunt of the front, otherwise he would not be injured.

Shirley also looked at Gu Cheng gratefully, suppressed the pain caused by the virus in her body, and said weakly, "Thank you...... Look at...... Honest. ”

Gu Cheng wiped the blood stains dry, and did not use the "Stroking Healing Technique" to treat the wound and restore health, because since he already knew that the tracker was in the brood, he could not waste even 1 point of spiritual power, and he had to accumulate spiritual power before the Armageddon.

"It's fine. You have a good rest, we have found the location of the adjuvant and will definitely make a vaccine to treat you as soon as possible. In the face of Claire and Shirley's gratitude, Gu Cheng also gladly accepted it, after all, he was a member of the protagonist group, and there was naturally no harm in being able to brush up on a wave of intimacy.

"Thank you...... Thank. Shirley's expression became a little painful, apparently the virus in her body began to torment her again.
