Review Detail of Arduril in Nine Star Burden

Nice cultivation system, totally unrealistic character behaviour. Mc's previous body occupant gest killed by his sister and MC flirts with her instead of pissing his pants from fear? If she slapped him again novel would be 3 chapters long. The constant switching between "I'll kill them all to level up" and "OMG I have to kill" In mc's attitude also makes no sense...
