Leaving the art (drawing skills) which is quite poor it's a decent manhua. MC is quite intelligent but in a reasonable manner and has a cheat power, an inheritance that caused his household to be wiped out by the Emperor, the story starts with him living a low-key life till he's girl dumps him and he has a "lucky" encounter.
Storywise it's very generic, the smart MC is what carries the story (so far), his methodical and careful approach is refreshing (except for one screw up (so far) that can be justified by being pissed off). So yeah, decent overall but nothing great, for those who like cultivation stories I guess.
