Demon Slaying, Gaining 60 Years of Cultivation From the Start - Chapter 855 - 599 Above the Realm of Transcendent Martial Arts

The world ended, seven days of earthquakes, volcanic eruption and then came the meteor storm, bringing something worse—mutation.Now, survivors are group into Shifters, mutated humans and normals.Ava Zhang was supposed to be a Normal. Useless. Disposable.Thrown into a military-controlled bunker, she is sorted into Level Three—the bottom rank, where the weak are left to rot. Starving, overworked, and surrounded by desperate scavengers, she realizes that in this world, strength decides survival.But Ava isn’t as powerless her hidden System activates. The Blueprint System—an ability that lets her design and invent anything, from weapons to high-tech defenses.

After transmigrating through ten years and silently registering his name at the Shanmen for ten years, the system finally issued Ye Changge his first task: to take in some disciples!

This is a very serious Xianxia book, but why the introduction I always want to describe it as: My second child is a giant, and there will be something going on in the future, and so on.

In short, you will understand after reading it, this is really not the YY of male species, what is missing, what is missing, etc. I am telling the truth.

- Description from novelbuddy

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.

Magus, Alchemist, Mesmer, Tamer, Hunter, Vampire, Werewolf, Dragonknight, Necromancer.....
