The quality of the writing and plot is really good. Characters are well done and progression is not jarring. This is undoubtedly a great high quality work but the story gets stale around chapter 1200 and I skipped to the end.
Dao_moon is right, he takes care to hide his drop talent in the wild but on day 1 boasts about to a stranger he just met and even turns down a secret keeping contract the other party herself proposed and straight up spills his talent. Absolute brain dead author
