Chapter 5: 　I was a zombie when I met again

However, before sweeping the city, Li Yichen first studied the fortifying enzyme. All living things in this world will evolve, whether it is zombies or animals and plants, naturally including humans.
How did zombies evolve is unknown, but human evolution depends on a substance taken from zombies or mutant organisms.
Li Yichen also bought this kind of thing called strengthening liquid in a survival base before, but unfortunately, I don't know if it is because he is not from this world, so this kind of strengthening liquid will not work for him.
However, although he cannot be strengthened, he also has an advantage, that is, he is not afraid of zombie virus infection. In more than a year, he has been injured by zombies more than once, but he has quickly healed. It is nothing like ordinary wounds. Two, unlike others, even a small scratch can cause death with a high fever and then become a zombie.
This is also the reason why Li Yichen has been wandering alone and refused to join any base. He is afraid that someone will discover his secret. When that happens, he will definitely become a test subject and be sliced.
Clicking on the page of Biological Essence, Li Yichen looked at an injection in the grid. There is also a number in the lower right corner of the injection: 3, which means he can exchange up to three injections.
These three injections were not provided by the zombie, but in the building he recovered, and an unknown number of zombie corpses were also recovered together. In fact, you need to wave a lot of zombies to extract An injection.
This injection is an enhanced enzyme, and it is divided into types. There is an endurance-enhancing enzyme in the grid. It is right to think about it. Zombies are always tireless creatures.
Exchange this enhanced enzyme injection with the purification point, Li Yichen rolled up his sleeves and stuck the needle on his arm, then clicked the button on the end of the syringe, and with a sneer, the blue liquid medicine inside disappeared instantly.
Just after the injection, the system sound rang:
"Ding! Found that discarded syringes are 100% recyclable garbage, do you want to recycle?"
Although it is automatic recycling, the system will prompt when recycling personal belongings belonging to Li Yichen, otherwise the clothes on his body will disappear instantly when he turns on automatic recycling!
"Recycle!"
Li Yichen said in his heart, and then he felt his own body. There was no change. Is the enhanced enzyme produced by the system useless? When I came to this world, I was destined to be an ordinary person?
"Host! Enzymes will work for all living things, but it takes a few minutes!"
Just when Li Yichen was frustrated, the system seemed to know what was in his mind and directly explained it.
"Is that so?"
Hope rekindled in Li Yichen's heart, but he didn't stand in the pit and waited foolishly. He climbed up and walked towards a building next to him, putting his hand on it-whatever it is, he will continue to live even if it is invalid. , Collect garbage first!
The huge building disappeared again, and a huge deep pit appeared on the ground. The foundation and the underground garage would take up a lot of space. But this time with preparations, Li Yichen would certainly not repeat the previous procedure, and went straight down. Go to a building.
When he received the third building, there was a sudden rush of heat from his body, but it quickly disappeared. Li Yichen felt it carefully and found that it seemed that his body had been strengthened, but because it was strengthening endurance. And the improvement is not very big, there is no way to verify it right away-you can't run wild for a while and tire yourself into a stupid dog, right?
Anyway, after confirming the effect, Li Yichen once again took out an enhanced enzyme to inject himself, because this strengthening can be superimposed, but according to the different eating conditions of each person, there is an upper limit for this superposition.
After the booster enzyme was injected, Li Yichen looked at the empty syringe, and suddenly thought of the licker just now. That guy is extremely fast, he belongs to the agile booster zombies. If they are recovered, will a new type of booster enzyme appear? ?
"This enhanced enzyme... should have something to do with the type of zombie, right?"
Thinking of this, Li Yichen turned his head and ran to the building just now. No matter what he saw on the road, whether it was a house or a car, he touched it with his hands or feet to recycle it—whether he sharpened his knife and chopped wood by mistake.
When he returned to the place where he killed the licker before, the ugly corpse was still on the street. As for the other two, Li Yichen didn't find it for the time being.
Holding the Tianya bow in his left hand, and pulling out a feather arrow with his right hand, Tianya slowly walked towards the body of the licker. Just a few steps, a few zombies walked out of the building on one side, dangling towards Li Yichen. Close.
"It looks! You won't have time to miss me in the future!"
Looking at the familiar faces, Li Yichen said faintly. Then he opened his bow and took an arrow and called them one by one, piercing all their heads. After putting them down, Li Yichen walked to the licker and touched it with his foot.
"it is as expected!"
Li Yichen was overjoyed when he saw that an injection appeared in the mall, and it was marked as agility-enhancing enzyme. Although endurance is also important, it is not as fast as agility.
Apart from anything else, I exchanged for the stamina injection to inject myself, and then took out the endurance injection and injected another. There is only one stamina injection, but the number of endurance injections has reached 68.
Moreover, Li Yichen also accidentally discovered that there was also a power-enhancing enzyme injection in the mall. Could it be that the tyrant's body is hidden in the building just taken away on the road?
I don't even think about where this came from, anyway, there are so many purification points, let's talk about it after injection!
After injecting the strength injection, Li Yichen looked at the corpses of several zombies over there, and walked over to retrieve them all. When collecting these corpses, Li Yichen didn't have any fluctuations in his heart.
He had rescued them once before, and if they knew how to be grateful, even if it was hypocritical, Li Yichen wouldn't mind making another move, but obviously they didn't seize the opportunity, that's not Li Yichen's problem.
Li Yichen has never thought about being a good person, but he retains some bottom lines for being a human being. At least if he doesn't threaten his life, he doesn't mind saving people. However, this depends on the goal. It is worthwhile to abuse good people. Is impossible.
After collecting the corpse, Li Yichen prepared to take all the surrounding buildings away, but found that there seemed to be movement in the distance. Looking up, the two figures disappeared in the distance.
"Did you go back and report it?"
Li Yichen frowned, immediately exchanged for a motorcycle in the mall, stepped up and chased in the direction of the two figures...
