one piece: gene extraction and fusion system - Chapter 274: The Cost of Favor

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.....

By the way, it wouldn't appear NTR or some bullshit harem of courtships. MC of course will have harem but not for cliches.

In the year 3000, humanity was forced to leave the earth when a sudden mutation caused more than 70% of the planet's population to mutate either into zombies, werewolves or vampires. The humans put up a fight but didn't have a chance against the united front of the monsters and they were forced to leave. At least those who were rich and lucky enough to leave.

A century later, the chaos on earth had calmed down but the humans who were left behind were treated like slaves and were forced to join one of the three factions: The Undead, The Cold Ones or The Lycans when they turned 16.

It was a similar story for Ashton, who was one week away from being turned into one of the monsters as it was his 16th birthday. He decided to run away from his fate and join the secret resistance to battle against the monsters.

However, his plans came to a standstill, when a series of misfortunes leads him to be bitten by a Zombie, a Vampire and a werewolf before either of his powers could manifest.

He ended up receiving all of their powers, but at the cost of his humanity. Yet, he wasn't willing to let his humanity die. No matter the cost.

Will he be able to live his life, or was it already too late? Which faction will he join? Will he be able to find the secret behind the mutation?

There were too many questions, and only one way to find the answers: follow Ashton's journey as he fights back to retain his humanity.

Bai Muchen had it all — not only was he the most renowned martial artist of the Nine Heaven continent, he even had the Five Meridians of Tianling and was engaged to Xuan Qingzhu, the beautiful daughter of his mentor. But everything falls apart when he’s set up by his fiancé and mentor during a cultivation session, and he is killed.

Reborn as a young man named Xiang Nan, the heir of a declining family, can Bai Muchen get his revenge?
