Warlock of the Magus World (WN) - Chapter 1005

Payload specialist, Tang Yue, who is a mechanical and electrical engineer by training, is left stranded on Mars when he receives news from his AI robot assistant, Old Cat, that Earth has exploded. He believes himself to be the last human in the Universe.

Though he received the skills necessary to teleport across worlds, the king who performed the summoning ritual attempted to trick him into wearing a slavery collar, this annoyed him so he kidnapped the princess and returned to Earth.

Because of boredom, Xu Jinyi entered a game. In this game called “Different Worlds”, he needed to play some cannon fodder or villain to live a happy new life.

Xu Jinyi worked hard to finish the game, and finally realized that this game was actually a scam created by Zhao Chengli specifically for him.
