Here is the list of novels where mc is very cunning. No cookie cutter novels like king of gods, legend of swordsmen or hootblooded teenage stuff like mga and agt type novels are mentioned. 

If you are tired of reading tr*sh cultivation novels then this list is made for you. I have put some novels with harem but mc in these novels are very cunning, so do not expect normal harem rather dont expectm more than 2/3 girl.

Warning :- Please dont read these novels if you like Against the gods, martial god asura, ancient strengthening techniques as you might not able to understand mc's decision and might leave bitter taste in you mouth
