Sir, How About A Marriage? - Chapter 842

Shin Kinghad is a kid that had been abducted and trained by a powerful underworld organization since he was three years old. After six years, he had been rescued by the Special Forces during their operation against that organization and was adopted by the captain of the special force group.

Since then, he treated the son and daughter of the captain as his own brother and sister.

Years later, he joins the greatest VRMMORPG of all time, [Destiny's Fate] online, due to repeated invitations of his brother. He creates havoc inside the game as he climbs his way from being a beginner player to a peak class expert.

But as he started to grow up, he became curious about his real identity and who his biological parents were. He tried to investigate it with the help of his brother and best friend. And after discovering his real background, he decided to follow his father’s footsteps and stood at the peak of the world using his Martial-Art Skills and Mentalism Techniques.

Ye Fan accidentally obtained a billion crystal technology system, and since then, he has become out of control.

Android: You do n’t even have a mobile phone system. I want to make it impossible for you all!
Ye Fan: Sorry, I researched it out, it seems to be more powerful than yours!
BMW Benz: Our engines are famous all over the world!
Ye Fan: Sorry, I do n’t have an engine, I only have magnetic levitation, and the speed is only a few times that of yours. Do n’t worry, take your time!
…
Enemy: Is he still human?
Who can stop this!

- Description from Qidian

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.....
