They are short stories with the same mc but in different bodies like a system

This story is part of a genre called Quick Transmigration, in which the MC (usually his soul/conscious) travels to different worlds with different identities. There he has tasks or missions (given by a system) he must complete in order to go to the next world. In some stories, the MC has to leave immediately after completion, or he can stay until his body in that world dies; The MC here, chooses to leave immediately afterwards. Each world has different sets of people, and each world has a 'different' ML (though in truth, most of the time it's the same ML (his soul/consciousness) chasing after MC to each world, so it is 1v1. Though I have no idea if it's the same in this story since there is a harem in one world (I've often seen situations like this explained by the ML splitting his soul/conscious between the bodies) If you have anymore questions, feel free to ask :)

I forgot to mention, the MC usually gets in this situation most often by dying, so usually the system offers to revive him/ grant any wish if he completes these missions. Sometimes there is penalties if MC does not complete the mission, often its death, or losing points (points can be awarded after completion and can be used to buy items/effects/tools that can help the MC complete following worlds easier)

There are love triangles, since his mission involves breaking up the male lead and the female lead. But nothing serious, since he is only playing a character.
