This one the bully is placed in the person he bullied body so it’s kinda revenge

Not revenge, but a nice iskeai funny and it’s kinda popular so you might have read it

This one is not reincarnation or iskeai but the revenge plot is nice with multiple characters seeking revenge and good fighting and training to be better fighters and there is a webcomic that is a continuation that is currently being updated.

Any recs where for regression, iskeai, reincarnation, leveling, or cultivation manga(hwa,etc) with no romance
Most preferred a revenge plot bc I feel like I've read it all ngl
