Review Detail of LazyGrammar in Reincarnation of a Worthless Man

Lots of potential. A good story could be great if more tragedy/massive war/conflict has him transcend his worthless self. MC is believable. Struggles with his character/personality from previous life. Not very apparent when younger but former personality comes out more as he ages. Looking forward to MC using more of his otherworldly knowledge to create more of his custom magic.
