Review Detail of gs_p in Rebirth of 1985's Best Doctor

liked the intro, started reading mtl, liked till 300ish chapter , it would be better to mention this book is about cultivation and alchemy felt like story is all-round FL is confused about what to do, ML is nice, loving but seems too extreme... , not sure why after reading about 500ish chapters felt boring and stopped reading, if anyone can give spoilers, would like to how the story ends
