The carefully cultivated heir of the Ning Family was killed, for the Ning Family, it was an extremely heavy blow.
Before annihilating the Tianjue Sect, the Ning Family had captured someone alive for interrogation, hoping to find out who had hired the assassins, though Tianjue Sect, consisting of seven people, disregarded rules when killing, they strictly adhered to one rule: until death, they never divulged who had hired them.
Therefore, the identity of the person hiring the assassin remained an unsolvable mystery. The Ning Family could only select a new heir.
