Anyway, Jiang Yuan and the eldest sister are going to go to the city to get some pressure cookers and the like to cook the meat of those mutated gray wolves, that thing is hard, and the ordinary stew has not changed for three hours, so it is still necessary to use high technology to conquer it.

As soon as the two arrived in the suburbs, they heard a loud noise, and they didn't find anything like mutated creatures, so in order to prevent a threat to the convoy not far away, Jiang Yuan took his eldest sister here.

Then, I saw a ...... who was not wearing underwear

Li Feifei turned around and saw the two people behind him, and said in surprise: "Someone is finally here, where are you going?" Can I follow you? ”

Jiang Yuan's perception is so strong, at first glance, he saw that the strength of this white coat was at least the third order, Jiang Yuan thought for a while, and said, "No." We're going to the city, and you can go to the capital base in the south by yourself. ”

Li Feifei was obviously a little overwhelmed by Jiang Yuan's neat refusal, but as a high-IQ talent, he quickly reacted and shouted at the two who turned around: "Hey! I have a mutation potion that can make ordinary people have abilities! ”

Jiang Yuan's footsteps stopped, this was obviously a big temptation, not to mention strengthening his subordinates, he also wanted his parents to have this or that ability, at least to protect themselves.

Jiang Yuan turned around and said, "Let me introduce, my name is Jiang Yuan, and I am the captain of a team not far away." We're going to the city looking for something, are you sure you want to follow us? ”

Li Feifei nodded and said: "My name is Li Feifei, I am a researcher of this research institute, that, my equipment is a little damaged, there is another research institute in the south, can you help me find the equipment?" ”

Jiang Yuan thought about it for a while, this matter was not difficult for him, compared to the mutant medicine, the dangers that he might encounter were insignificant, so he agreed.

Jiang Yuan waved the equipment pointed out by Li Feifei into the space, which made him even more excited, and he was going to pick and choose to take some small equipment away, but now he asked to take away all the useful and intact equipment. Jiang Yuan didn't talk nonsense, we have a lot of space, but we are capricious, and he has installed everything Li Feifei asked for.

……

There were no waves in the city trip, and after collecting a few crystal nuclei of second-order zombies, he found what he needed, and by the way, Jiang Yuan also swept the supermarket market he saw on the road.

There were no living creatures in the other biological institute, just two zombies, and no other creatures.

However, there is a good harvest this time, I don't know which local tyrant bought a German conquistador series RV, this mighty big guy, once worshiped as a god car by many doomsday fans, so it has the title of a doomsday RV. There are all kinds of facilities in the car, Jiang Yuan silently thanked the local tyrant, and then excitedly changed into a new car, uh, he can't drive, naturally the eldest sister will drive.

Back at the team, Jiang Yuan used the car as a new high-level conference room, and it was also the first car to be new. Yang Ziqing's mother also went to this car to rest, after all, the shock absorption effect of a luxury RV is much better than that of a big truck. Jasmine Rose and the others naturally moved over, so that the original car was empty, and naturally it would not be left idle, just when Li Feifei needed to continue research, he turned this car into his experimental car.

Li Feifei's test car was driven by Zhou Jun, and Jiang Yuan was very relieved about its safety, because it was bumpy on the road, and it couldn't carry out any too precise experiments, and those equipment naturally couldn't be used, so he didn't worry about the damage to high-end equipment.

Li Feifei's identity Jiang Yuan did not publicize it vaguely, but only said his identity as a third-order mutant, for the powerful team members, everyone is naturally very welcome, especially some scheming women, without a trace of Li Feifei, without a trace, in this last day, a strong man is undoubtedly a good guarantee for survival.

The convoy was advancing, but Jiang Yuan was not resting in the comfortable luxury RV, but in the experimental car.

Jiang Yuan sat on the chair and asked expressionlessly, "In other words, the mutant elixir you mentioned has not actually been successfully developed, right!?" ”

Li Feifei sat opposite with some embarrassment, and said: "To be precise, yes, but I have already found out the approximate reason, according to the experimental data, theoretically humans can use that potion without a collapse similar to that of a mouse." ”

Jiang Yuan was silent, thinking about it, Li Feifei thought that Jiang Yuan was going to drive him out, and said in a little hurry: "This is not successful, but my other potions are absolutely correct, and I have already experimented on myself." ”

Jiang Yuan saw his anxiety and said with a smile: "Don't worry, you are already my teammate, no matter whether you really research something or not, I will take you with me." ”

Li Feifei put down his heart and thanked him with a smile, and then reported his research results to Jiang Yuan.

Jiang Yuan determined that there are some such anti-heaven existences in this world, and this Li Feifei really has good research results.

The first is the enhancement potion, which is the finished product of his experiments. This enhancement potion is an active substance extracted from the corpse nucleus of zombies, and its main raw material is the corpse nucleus of zombies. This is a mature potion ratio, that is, theoretically, if you provide a first-order corpse core, you can make a first-order enhancement potion, and if you provide a second-order corpse core, you can produce a second-order strengthening potion, and so on.

And its effect, the effect of the first order, is to improve the physical fitness to the middle level of the first order, that is to say, the strength is strengthened to the level of the second order. In the general process of devouring corpse cores, to become a first-order enhancer first, depending on the physical fitness, one to three first-order corpse cores are needed, and to evolve to the middle stage of the first order, that is, to have twice the strength, three to six crystal nuclei are needed.

What about first-order enhancement potions? Its raw materials only require one-third of the corpse core, nine to eighteen times the effect, which is enough to make any organization or individual who wants to have a certain amount of power in the apocalypse go crazy. Of course, a Buddhist man like Jiang Yuan, who has no ambitions, naturally does not have such great ambitions. However, this did not prevent him from wanting to strengthen the potion for his family.

The results of this research alone are enough to prove the value of Li Feifei, of course, the existence of demons is used to destroy the worldview of ordinary people, Li Feifei's research results are far more than that, not to mention the mutation drug, there is another medicine.
