My Time Can Be Reversed

Lin Yuan, a game boosting professional, died from overwork and gained a superpower—Death Rewind. Upon death in a dungeon/other world, the player is forced to revert to the previous "save point" (randomly or manually set by the system), retaining all memories, muscle memory, and some items. The cost is consuming "life time" in the real world. - Skills aren't acquired with a single click; they're developed through repeated deaths, creating "muscle memory." - In dungeons, you can experiment, you can die, and you can test NPC reactions. - After killing the same boss multiple times, you can beat it even with your eyes closed.
