Bai Cheng'an, a disciple of the Xuanyin Mansion, awakens a patternless gray seal regarded as a useless seal, only to find that it cannot release lethal blows, but can only reinforce existing foundational techniques. With the data assistance of tester Cheng Yingxi, he relies on reviewing and polishing his fists, steps, and shields to break through all the way from the bottom to the mansion trial. Facing the continuous suppression from genius Situ Yaochen, Bai Cheng'an stacks his foundational power to the max, contending against the nine-patterned golden light with a dark giant seal, and drives the sect to rewrite the old criteria for spiritual seal evaluation.
