MTL - My Girlfriend is a Zombie - Chapter 1260 a game

And so Arascus, God of Pride, waited. He waited for his defeat as the forces of Heaven & Hell combined descended upon him. He waited as they tried to kill him. He waited as they locked him away. He waited for a thousand years in that dark prison.

‘Yoknapha,’ an international and well-known villainess actress, is suddenly transmigrated into a series she once starred in as ‘Bai Yu,’ a daughter of the senior chancellor. If this world follows the same plot of the story she knows, she will always lose to ‘Bai Hua,’ the heroin.

Nevertheless, if she loses this time, the one who will receive disgrace is not Bai Yu, but Yoknapha herself. That is why this time she will not surrender to the dreadful fate!

If it is determined that a heroine will end up with a hero in every love story, this one has to be different. She will be a villainess who gets to be paired with a hero herself. If wicked deeds bring what she needs, she will stay evil to the end!

That will be easier if a mysterious man Bai Yu does not remember exists does not appear and makes her heart pound like this!

The story of otaku building a harem! School flower, loli, wife, mother and daughter, mature woman, teacher, nurse, queen, all kinds of beauties, three steps to push a girl, five steps to a group, harem group, infinite warmth, so cool that you always need to prepare a tissue for easy reading !

- 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.....
