Doomsday Loop: I Restart Infinitely on the Same Day

The apocalypse came and I was trapped in the same day. If you die, restart. If you fail, try again. Infinite loop, infinite trial and error, infinite getting stronger. Others are struggling to survive in the last days, I gain experience, stock up on supplies, and reach the top in the last days! This time, I want to live like the apocalyptic ceiling!
