Like the Southwest Base, a base that can clean up all the surrounding zombies is still a very small number after all, and the vast majority of bases are in a precarious situation.

Whether it's a large base or a small base, as long as people gather, zombies will be attracted.

If there is not enough defense and there are a large number of zombies around, even if these bases can withstand the first round of attacks, they will not be able to withstand the next wave of zombies.

The base in the northwest, because of the low population density, faces a much better situation than the east, at least, there are not so many zombies.

Lian Zi repaired in the middle of the night, recovered, and began to slaughter the zombies in the city.

Having the aid of the crystal nucleus will indeed increase one's cultivation speed a lot, especially to the point where Lian Zi is like this, and the concentration of aura in the air is already a bit insufficient for her.

In this way, if Lian Zi wants to quickly improve his cultivation, he must use external forces, and at this time, the crystal nucleus has become a good choice.

Moreover, Lian Zi can quench out the impurities in the crystal nucleus, so you don't have to worry about using too much to affect the foundation.

It's just that although the crystal nucleus is easy to use, with Lian Zi's cultivation speed, the demand for the crystal nucleus is not a small amount.

Lian Zi has a lot of crystal nuclei, whether it is from killing zombies by herself or going on a mission with Murong Yue, he gives her according to the remuneration, there are a lot, at least for ordinary abilities, it is definitely an astronomical amount.

Lian Zi has not made specific statistics, but she estimates that it should add up to several million, maybe close to 10 million.

Lian Zi has used less than a quarter of it now, and it stands to reason that she doesn't need to worry about the crystal nucleus.

But the opposite is true. Even Zizi's crystal nuclei are low-order crystal nuclei, most of them are first-order, not many second-order, and even fewer third-order.

The lower the grade, the less spiritual power it contains, and the first-order crystal nucleus is not enough for Lian Zi to plug between his teeth. Not to mention that after tempering, some of the spiritual power in it will be lost.

Therefore, it seems that Lian Zi has a lot of crystal nuclei, but compared to her needs, it is still not as good as her. Not only does she have to prepare for this stage of the breakthrough, she also has to think about what lies ahead.

In this case, there was an opportunity to collect crystal nuclei in front of her, how could she miss it?

After Alan had eaten enough, Lian Zi summoned her back, and she herself began to slaughter with a spirit sword.

Lian Zi's method of killing zombies has been so skillful that his body can react without thinking deliberately.

With the blessing of spiritual power, Lian Zi killed tens of thousands of second- and third-level zombies without much effort, which was also mixed with a lot of mutant beasts, zombie beasts and mutant plants.

There is an aquarium in Jiucheng, there are many sea creatures in it, after the end of the world, I don't know how they evolved, they can actually live on land, such a strange thing, naturally attracted Lian Zi's attention.

After experiencing the things of the test subject, Lian Zi is very sensitive to this kind of thing. Although these animals have not been experimented on by humans, since such an unreasonable mutation can occur, it is not a harmless thing.

Prevent problems before they happen, strangle the danger in the cradle, whether they will grow into a terrible existence or not, even Zizi doesn't want to let go.

There are many such things, and when you encounter zombie beasts, mutant beasts and the like that you think may be dangerous, even Zi will not hesitate to do it.

Lian Zi didn't know if she was cruel, after all, even if they became mutant beasts, they were still life.

But she will not hesitate, in this war of natural selection, either you die or I die.
