There is always such a person in the world who likes to take their ex/Bai Yueguang/best friend as a stepping stone for their love.
These exes/Bai Yueguang/Girlfriends are called female supporting roles. They obviously did nothing. Just because they were involved with the male and female protagonists, they were trampled on, hurt, and even left a shadow that will never go away for a lifetime.
Jiang centrifugally felt sorry for those innocent girls, so he traveled from one world to another to help them cross that hurdle.
However, after a certain world, the mission is obviously wrong.

Kaius just wanted to unlock his class - instead, he restarted the apocalypse. After years of training, Kaius has barely acquired the first two of his family’s legacy skills. Powerful and vanishingly rare, the method of creating them is a secret people would kill for. Now they might be the only thing that keeps him alive. Narrowly surviving a bandit ambush, he gets trapped in the Great Depths- a world spanning dungeon. To escape, he will have to slay one of the Guardians that defend the exits; a feat no one without a class has survived. Ever. If that wasn’t bad enough, if he succeeds he will reignite a forgotten trial that nearly ended civilization. -Runic-Tattoo Wizard/Spellblade in a world of sorcerers -Exceptional MC, with some initial Slow Burn elements -Large scope, inspired by epics such as Azarinth Healer, BTDEM, PH, and more. -Third Person POV, with a 99% MC focus -Numbers go brrrr -Attack Badger (Friendly?) -Battle maniac MC who is not a murderhobo -No harem, romance, or VR
