"Now we have to go back and find a car first, after all, we will be more dangerous if we don't have a car, and our food is locked in the car! If we don't go back, we won't have anything to eat. Wang Yu also nodded and agreed with Chu Tianyu's statement, now it can only be decided for the time being, if there is no car, they only rely on their legs to walk, when they can go, it is easier to be besieged by zombies!

There was nothing better for them, and in the end they all agreed to Chu Tianyu's proposal, and after a short rest, they were ready to go back to find their car.

The road was difficult, and it was not smooth when they went back, although the zombies did not gather together to attack them as they did when they came, but there were still a lot of zombies on the street, and as soon as they came out of the hiding place, they saw a zombie rushing towards them.

Several people quickly entered a state of readiness, because they knew that the zombie had a crystal nucleus in its brain, so Si Jiali mainly pressed his head when attacking, striving to split its head to pieces, so that the crystal nucleus would be easier to be discovered.

Sure enough, after killing this zombie, the more careful Wang Yu discovered the crystal nucleus in the zombie's head.

"Hey, what's that?" Wang Yu pointed to the heads of the zombies and asked, he just seemed to see a flash of light in the minds of the bunch of zombies.

"I'm disgusting, who knows what it is!" Zhu Lin said with some disgust, Zuo is just a brain pulp or something, what else can there be, this Wang Yu is really, what is there to see about such disgusting things, and he deliberately let them see it, is it deliberately trying to fix them?

Chu Tianyu heard Wang Yu's words. He used the weapon in his hand to flick the zombie's brain, and a colorless crystal nucleus fell down.

"Huh! Does this zombie still have crystals in its head? Hehehe~~~" Liu Yue said with a smirk.

"These zombies were all human beings like you before they turned into corpses, have you ever seen anyone with crystals in their heads?" Wang Yu looked at this guy who spoke without thinking like a mentally retarded person, he was really able to think, if crystals grow in people's heads, then jade, diamonds and other things are also specialties in the human brain?

"That's too, hehe~~~ A slip of the tongue, what could this thing be?" Liu Yue also knew that he had said a mentally retarded guess, and smiled a little embarrassedly.

"I've smashed zombies' heads before when I killed zombies, but I've never seen this thing. And now, when the zombies are upgrading, they have found this thing in their heads. Does it mean that their upgrades have something to do with this thing? Si Jiali's side tapping guided everyone's thoughts.

"It's also possible that when we play online games, don't we put gems on them in order to make the weapon powerful? Maybe it's the zombie's own gem. Han Weiqi made a bold guess.

"Hehehe~~~ Han Weiqi, is your brain hole too big? They're all dead, and they don't have an IQ at all. How do you know how to set gemstones for yourself? Liu Yue said with a laugh.

"Maybe it's instinct. Natural selection of the fittest to survive. Since they have created nature, they want to survive, but after all, humans have the intelligence and know how to use their prerequisites to solve them. They are always in a passive state, and they naturally need to evolve, and now this may be their instinctive evolution. Chu Tianyu also interjected on the side.

"You're thinking too complicated, aren't you?" Liu Yue asked suspiciously.

"No matter how complicated it is, at least I think it's a good thing, maybe it's the energy it gives to the zombies and makes the zombies stronger!" Si Jiali took over the baton and continued to guide everyone.

"Then you say this thing will be useful to us Adepts?" Wang Yu asked the key point of the question again.

"Hahaha~~~ It's useful, don't you still want to put it in your head?" Liu Yue said with a smile.

"It's not necessarily that zombies are embedded in the brain, we also have to be embedded in the brain, there may be other ways, it's better for us to collect such things when we see them all along the way, and then slowly study its function, anyway, it's a convenient thing, but in the end, this thing is useless and not a waste of our time." Seeing that this link was almost over, Si Jiali took the opportunity to propose the idea of collecting the crystal nucleus, and only after collecting the crystal nucleus could she take the opportunity to say that she had discovered that the energy in the crystal nucleus could be absorbed for her own use.

"Belle thinks so much, how old am I than Belle! None of the beauties are so careful. Zhu Lin didn't say a word for a long time, she had never played online games before, and she didn't know anything about those things at all, so she didn't know anything like a few men, but Rao was like this, she also felt that Si Jiali was thinking too much, if it was her, she wouldn't have been able to find the crystal nucleus at all, let alone think about the value of the crystal nucleus, but Si Jiali was like a middle-aged man with a mature mind who could think of everything.

"There's no way, the environment forces people to grow up rapidly, and I am also forced by the environment to have to think more about anything." Si Jiali pretended to be helpless and said.

In fact, in her previous life, she never cared about this, and when she knew the magic of the crystal nucleus, Yun Shuirou's ability level was already level 3 or 4, although the first few levels were easier to upgrade, but in the end, it was a distance, and no matter how much she chased it, she couldn't catch up, not to mention that at that time, she was so stupid that she gave her hard-earned crystal nucleus hands to Tang Zehao for him to use, and in the end, there were very few that fell into her hands, which is also the basic reason why her ability in her previous life has been rising very slowly, She thought that as long as she was good to Tang Zehao, one day Tang Zehao would be moved by her, but what she was waiting for was not his touch, but his betrayal, in fact, if her ability could be higher in her previous life, Yun Shuirou would not be willing to send such a well-controlled person to the laboratory, but in the later stage of her previous life, her level was too low compared to others, and she couldn't keep up with Yun Shuirou's footsteps, so she was naturally ruthlessly abandoned.

Now think about her previous life, she was surprisingly stupid, in that environment, she didn't want to improve her strength quickly, and she actually had the leisure to please men, no wonder she was abandoned in the end, not to mention such a cruel environment in the last days, that is, in the era of peace, if the gap between the two husbands and wives is too big, the person who is much behind is easy to be abandoned. Not to mention the era when even relatives could be pushed out, it was reasonable that she would be abandoned in the end.

In this life, although she knows that Chu Tianyu will not treat her like Tang Zehao, but people's hearts are fickle, she can't just rely on Chu Tianyu's friendship with her now to judge what will happen in this life, the key is to continue to work hard to strengthen herself, so that the gap between her and Chu Tianyu is not too big, the distance between them is not too far, and the relationship will naturally have more protection.

"Yes! Now that the environment is so bad, you have to use your brains more, and Belle will be our role model in the future. We have to think twice about what we do in the future! Wang Yu said with emotion. He didn't expect Si Jiali to have such an awareness at a young age. Knowing that he had to think more about everything, on the way to escape, he saw many women who could only scream, cry, and have no brains, and most of them were the happier they were, and they often died the earliest. There are also a few women who quickly cling to the powerful men in the convoy for protection in order to survive. He is not averse to this kind of now. After all, as long as he can survive, the process is not important, but in his heart, he still looks down on such a woman. Now I didn't expect to meet a thoughtful and calm girl like Si Jiali, but he was one step late, the beauty was already famous, and he could only stand in the position of a friend no matter how much he admired Si Jiali.

In the end, the vote unanimously decided to move to the location where they parked while killing zombies all the way to find out if there was a crystal nucleus, because the zombies came to evolve last night, so seven or eight out of ten zombies they killed had crystal nuclei, and by the time everyone sat in the car, they had already picked up dozens of zombie crystal nuclei.

"Judging from the situation we killed, the improvement of zombie ability really has something to do with these things, and the zombies with this thing are obviously much stronger than the zombies without them." Si Jiali brought up this matter when she sat in the car, believing that as long as she was not a fool along the way, she would find out about it, so she didn't care about mentioning it.

"Now it seems that the upgrade of zombies is indeed related to this thing, what we have to do now is to find out whether this thing is useful to us." Wang Yu also nodded and said. Of course, he also discovered this key point after killing all the way, and the only thing that he can't be sure about now is whether this thing will be useful for them, if they can really rely on this thing to upgrade......

"So how do you study it? I can't see anything just by looking at it! Zhu Lin looked at the pile of crystal nuclei and asked questions.

"You really can't just do it, let's hit the road first! Slowly study on the way. Chu Tianyu proposed, and then gave Si Jiali a look, and asked her to start the car and continue on the road after watching it.

Si Jiali naturally received Chu Tianyu's hint, and pretended to hold a few crystal nuclei in her hand to play and study, and after a while, she ......

"Huh!" Si Jiali pretended to look at the crystal nucleus in her hand in disbelief.

"What's wrong with Beauty?" Chu Tianyu saw that Si Jiali had made a move, so he naturally asked very cooperatively.

"Tianyu, I seem to feel that there is a power to pass it out." Si Jiali said uncertainly.

"Really?" Han Weiqi, who was sitting in the back row, was the first to ask curiously.

"Hmmm! I didn't see a reason for it for a long time, but just now I tried to cover it with my own ability, and I actually felt that energy came out of it and entered my body. Si Jiali saw that someone was cheering, and immediately turned around and pretended to be shocked and said.

"Really? Didn't you feel wrong? Zhu Lin also poked her head and asked.

"It's true, you can try it if you don't believe it." Si Jiali pretended to try again, and then said to the people behind him with certainty that because everyone wanted to study the usefulness of the crystal nucleus, except for Zhu Lin, who disliked that the crystal nucleus was dug out of the zombie's head, everyone had a few in their hands, and now after listening to Si Jiali's words, they naturally tried it without any hesitation.

"Beauty, bring me a few too." At this time, Zhu Lin was also excited, and she couldn't care about disliking it, so she anxiously asked Si Jiali to bring her a few for experiments.

Si Jiali took out a few from the bag containing the crystal nucleus and handed them to Zhu Lin, and several people fumbled around trying to cover the crystal nucleus with their abilities, and sure enough, they were all pleasantly surprised to find that there was really energy transmitted from the crystal nucleus to their bodies.

"There's really energy!" Liu Yue exhaled in surprise.

"Yes! I feel it too, maybe we can really get through this upgrade! Han Weiqi also echoed with some excitement, they were originally very difficult to mix in the last days, if the zombies were upgraded and not let them upgrade, then they would have no way to live, fortunately, there was such good news to cheer people up at this desperate time.

"We really gained a lot from coming out this time, I think we don't have to run in a hurry, let's go while killing zombies! Just in time, when no one has discovered this secret, let's raise our level first, and we will have a better foothold in the base in the future. Wang Yu made a timely suggestion.

"I agree, let's slow down and find people while killing zombies! It doesn't matter if this task is not completed, anyway, the rewards are not very many, and the most important thing is for all of us to raise the level. Si Jiali is waiting for everyone to say this! It's just that she can't upgrade because she can't upgrade, and she doesn't want to eat white food, but in fact, she really can't look down on that reward, and she didn't hurry up to upgrade the main thing, she must raise her level before Yun Shuirou this time, and then develop a force that can compete with Yun Shuirou, so that she has the qualifications to say revenge.

"Yes, let's upgrade first, as for the task to be completed, it is naturally the best, if we can't complete it, we won't lose a trip this time." Chu Tianyu, who was driving, also seconded the proposal, the most important thing for him is naturally to upgrade, as long as the level is high and he has the ability to protect himself, other things will follow, if he has no ability, even if he has more food, he will sit and eat empty, and when the food is eaten up, he will not have the ability to look for it again, and in the end, he can only be reduced to the lowest level.

When he broke out at the beginning of the last days, he was reduced to the lowest level of people because he had no special abilities, and that kind of taste is only known to those who have tasted it, and he doesn't want to be reduced to the lowest level of people in this life, that is, he can't become a superior person, and he must become a person who is not easily bullied and insulted by others.

For several other people, leveling up is indeed more attractive than supplies, so everyone decided to change their strategy and define the main task as an upgrade, and the task of finding people was completed as a side quest.

After making a decision, Chu Tianyu and a few people continued to go on the road while slashing zombies, not knowing how worried Chu Tianjin's party in the base, who also knew about the zombie upgrade, was worried about their safety. (To be continued......)
