I Was Rejected by the Main Character in a Romantic Fantasy - Chapter 23: Mercy.

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.

[I traveled through time and entered the Taoist holy land Tianshi Mansion to practice. 】

Lei Jun: “Very good, I choose to sign.”

From now on, the benefits will not be lost, and the troubles will not come to you.

Life is in a simple mode, and you can watch others’ thrilling clouds rise and fall indifferently.

A man is reborn into the world of Avatar: The Last Air Bender as a waterbender from Katara's tribe. Best of all, he was the same age as her, and he had a system with him to help.He knows the future and a system that lets him continuously get stronger by completing quests or long-term missions, as well as giving him the ability to copy abilities from others for himself. He will become invincible in the world of Avatar, even more so than the Avatar himself.

Why, seems like I’ve become a haunted portrait.
