Douluo's Insurmountable

I traveled through time and became the son of a blacksmith in Douluo Continent. Good news: I know the book by heart and know all the opportunities and dangers. Bad news: I can't tell anyone. So I can only pretend to be a genius with "extremely good luck". Use "coincidence" to save the damned person, use "intuition" to avoid the pitfalls that should be stepped on, and use "reading too many books" to explain all the unpredictable things. Tang San calls me brother, Xiao Wu calls me benefactor, and the master calls me a tactical genius. Only I know - I'm just a regular guy who reads the script.
