Yang Zhengmao's affairs had no effect on Chen Lin.
Over the following days, he stayed in the Cultivation Chamber, monitoring Zuo Yunliang's changes while taking the opportunity to study the Divine Light of Annihilation.
This secret art was profoundly intricate. It primarily explained how to fuse the meaning of annihilation into the soul, then release it in the form of soul light.
Its power mainly depended on the depth of one's comprehension of the meaning of annihilation.
