Devil Slave (Satan system) - Chapter 1291: Commander marian’s Pain

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.

The boy who Sneaks in My Bedroom Window

A young orphaned boy named Mu Yi is saved by an old travelling Taoist Priest. They travel the world ‘scamming’ people by ‘exorcising ghosts’ and ‘slaying demons’, that is until the old Taoist Priest dies and Mu Yi is forced to realise that all is not as it seems. He was told stories of armies of ghosts, hordes of zombies, horrifying demons, and worst of all, the cultivators who controlled them.

Mu Yi takes his first steps towards rising to the top of this dark and cruel new world.
