Qin Nian, the illegitimate son, was tricked by his half-brother Qin Hen into practicing the family's cultivation technique. His father, Qin Yuanshan, then crippled him — destroying his dantian and breaking all four of his limbs — under the pretext of "defying clan rules." His mother, Lady Xu, was killed while trying to protect him.
Abandoned in the wilderness, Qin Nian's burning hatred awakened the Nine Dragons Supreme Divine Body (the strongest divine-level bloodline). He was rescued and underwent dual cultivation with the mysterious expert Bai Tianhan, after which he changed his name to Xu Nian and fully restored his cultivation base.
