The Apocalypse Grinder (LitRPG Apocalypse, Timeloop)

The tutorial proved a challenge too great for Ronan Steele. Fortunately for him, death was just the beginning. Ronan was in a meeting when the apocalypse struck. Now, rather than spending his day explaining optimised spreadsheets to rich old guys, Ronan now has to defeat hordes of angry goblins to complete the tutorial and make it back home. However, the Earth he left behind is no longer the same, relatively peaceful world. Merged with three other planets during the apocalyptic integration into the system, the planet he now calls home is filled with mutated, dangerous beasts and even more dangerous invaders from other worlds. In order to protect his peace and get revenge on the system which forced him into this mess, he must use his overpowered heritage to continue amassing strength. Because unlike other challengers, Ronan has an advantage that not even the system can fix—when he dies, he wakes up at the beginning of the tutorial once more. Not only does he get to return to the beginning, but he keeps his skills and gets an xp boost for his next life. The further he goes, the more powerful his heritage grows. Eventually he will be able to keep even his levels and items after death. Most people would crumble when faced with the prospect of an infinite apocalypse, but Ronan is a tenacious fellow. One goal drives him through his endless fights—to bring down the very system that forced this tragedy onto his world. The content warning tags are to allow me creative freedom. The fight scenes do get a little visceral as that is simply my writing style. The mc swears quite a bit, which is his personality. As for the sensitive content, I mostly don't write things like this but for the occasional scene to develop the mc I felt it was necessary since some readers won't want to read this. I will try to include warnings per chapter when there is such content. What to expect? MC starts out fairly average, but quickly grows in strength due to his heritage MC morals and perspective develop as he experiences the apocalypse through different lives MC is willing to kill, especially monsters, but is not cruel or inhumane. Story mostly revolves around the protagonist, but there are occasional POV shifts to develop the story The system is really crunchy. Expect a LOT of numbers going up. Average chapter length of 1500-2000 words
