A cold air rushed out of the door, and Shi Dalong took two steps back in horror, not knowing what he was afraid of. And Dong Xin also reflected abnormality, covering his mouth and nose, and kept coughing.

"Leader, this stuff stinks. ”

"Stinky?" At this time, Yan Shifei was even more strange, he turned his head to look at Jinghan and Ma Hua and asked, "How do you feel?"

"No, it's a cold storage, right?"

"I don't think there's any difference, if you don't come here, I won't be in this container. ”

Hearing the answers of the two, Yan Shifei was even more puzzled in his heart, he didn't say anything, turned around and walked in.

Walking into the container cold storage, the furnishings inside are still exactly the same as when Yan Shifei left before. The shelves in the front rows where blood samples were stored were empty, and the two rows in the back were neatly arranged for the X1 virus and T1 vaccine.

Yan Shifei walked around inside, but didn't find anything different, he tried to reach out and take out a shot of virus reagent and a tube of vaccine liquid and studied it carefully.

"Wow, it's so cool in here. At this time, Jing Han and Ma Hua also walked in curiously, and the two sighed, and then they were attracted by the blue and green potions placed here.

"X1?ah, Yan is wrong, is this the virus you are talking about? Why are there so many here?" Jing Han asked curiously, holding a test tube containing a green liquid in his hand.

Yan Shifei put down what he was holding, walked up to Jing Han, and replied, "This cloud pharmaceutical factory is actually a secret virus research base of the military. When I first contracted the X-virus, I was brought to the underground research room here. Later, when the epidemic broke out, everyone in the pharmaceutical factory turned into zombies, and I escaped by accident and discovered this place by accident. ”

Ma Hua held a glassware containing a blue reagent in his hand, walked up to Yan Shifei and asked, "Old Yan, what is this T1?"

"I read in the notebook of a researcher here that T1 is a vaccine for the X1 virus, which can inhibit the X1 virus, but I have never tried it, and I don't know what the effect is. ”

"Are you saying this thing is a vaccine? Could it be that the reason why those zombie monsters outside are afraid to come in is because of these TIs here. MCA immediately thought of the crux of the matter.

Yan Shifei scratched his head and said, "I don't know, but I remember that when I came here, in addition to these reagents, there were many blood samples here." It stands to reason that the zombies should gather in this place as soon as possible, but for so long, this warehouse has been quiet, and no zombies have ever entered. ”

"Ordinary zombies don't dare to come in, but you can come and go freely, isn't it ......" Ma Hua muttered in his mouth, suddenly seemed to think of something, turned around and walked out of the container with the T1 reagent in his hand.

Yan Shifei and Jinghan didn't understand what she was going to do, so they hurriedly followed out.

After coming outside, Ma Hua first walked to Dong Xin's side.

"MCA, what are you holding in your hand, why does it stink so much, I can't stand it. Dong Xin covered his mouth and nose and retreated again and again, as if he didn't want to stay by MCA's side for one more second.

Seeing Dong Xin's reaction, Ma Hua didn't say anything, but walked directly to Shi Dalong. But before she could take a few steps, Shi Dalong, who was standing in place, escaped from the warehouse with a strange scream like a cat that had been stepped on by its tail.

"Sister Hua, what are you holding? Why do I feel so horrified, my body seems to be pricked with needles. ”

Shi Dalong's shouting came from outside the warehouse, and Ma Hua did not chase him out, but retreated to Yan Shifei's side, and said in a very positive tone: "Old Yan, I think these zombie monsters, that is, the virus infected, are graded. ”

Yan Shifei didn't react at once, and opened his mouth to ask, "What does grading mean?"

That is to say, this virus should have a new variety of evolutionary mutations, the most primitive is the X virus, and X1 is the upgraded version of the virus. The normal zombies and Stalon outside are infected with this X1, so they will reject T1. And Dong Xin's infection of the virus is a little more advanced than that of ordinary zombies, so the rejection will be a little smaller. And the virion you are carrying now should be one level higher than X1, so it won't react to T1. ”

"X1?T1?level?" Yan Shifei slowly chewed on the meaning of MCA's words, and scenes from the past gradually appeared in his mind, and suddenly he thought of a possibility, which made him feel surprised and worried.

He reached out and took the bottle of T1 reagent from MCA's hand, took out a pile of syringes from the warehouse, then pulled out a syringe of T1 and walked outside.

Coming to the factory compound, Shi Dalong was venting his frustration in front of a zombie monster. When he saw Yan Shifei coming out, he was just about to step forward to say hello, but a sense of fear hit his heart, and then he made the same action as a few ordinary zombies around him, turned around and ran away.

Shi Dalong looked back to observe Yan Shifei's abnormality while running, and when he saw the things in Yan Shifei's hand, he couldn't help shouting: "I'll wipe it, old Yan, what are you doing with a syringe? If you want to get an injection, I also want Dong Xin's beauty to give me a shot." ”

When Yan Shifei saw his appearance, he couldn't help but smile bitterly and shouted: "You catch a zombie and come back, or I'll stick this needle into your ass." ”

When Shi Dalong heard this, he hurriedly caught up with a zombie, raised his foot and kicked the zombie's legs off, and then retreated far away.

"Come here yourself, I don't dare get too close to you, there's something strange in your hand. ”

Yan Shifei ignored him, walked quickly to the zombie whose leg was broken by him, grabbed the arm of the living dead, and injected this injection of T1 reagent along the position of the veins.

After the injection, Yan Shifei threw his hand aside and threw the needle aside, and then carefully observed the zombie's reaction. But ever since it was injected with T1, the zombie monster has been lying there motionless. He waited for a long time, and finally couldn't help but kick the zombie's broken leg.

"Ahh

Yan Shifei was startled by the scene in front of him, and he slowly approached the zombie that had woken up again.

"Hey buddy, can you hear me?"

"It hurts...... It hurts me to death. The resurrected zombie only said a few words, but this made Yan Shifei suddenly see hope for solving the virus crisis. He immediately walked over to the man and squatted down, wanting to ask him something, but the man suddenly raised his head and grabbed the corners of Yan Shifei's clothes with both hands, said "help me", and then fell straight down.
