The novel is about an online game that just launched. In this game you can choose several races, the mc ends up choosing the race of the slimes (considered by the players as one of the weakest, but the truth was that they are considered rivals of dragons), later ends up achieving a class called cultivator. I know tbm that he goes to the realm of slimes go through a challenge to further evolve his race. Does anyone remember the novel's name?
Why is it that every story regarding a slime is r-rated.. I mean, not all slimes are evil monsters, you know.
I saw one about a mc that after killing demon king opened a massage place with his slime and likes to get kinky with female customers https://www.novelupdates.com/series/my-immortality-its-in-a-death-game/
