Ada's words were not untrue. At first, Su Yu felt nothing, but as he continued, he began to notice a subtle difference. He could vaguely sense a mysterious energy attaching itself to his skull, causing a certain change in the bone. Although the transformation was faint, he believed that if he continued, he would eventually achieve a major transformation and gain divine bones.

The ones with the most notable progress were Zhang Zhongmou, Ma Ziye, Ren Honglin, Murong Dingyuan, and Ruan Minghong.
