Lin Rui was in an observation room of the underground base, watching Ji Xueying's Dragon Transformation in the Dragon Transformation Pond.
Ji Xueying's transformation process was nearly identical to that of Shangguan Tianyi; it started with the growth of flesh and bones outside the layer of bone armor, forming a complete chest framework, followed by the internal organs, limbs, and skeleton of a Battle Dragon.
Though it may sound simple, the actual process was complex and perilous.
Ji Xueying, possessing Emperor Level Bloodline Power, faced a challenge tens of times more difficult than other Martial Cultivators when advancing.
Lin Rui was Ji Xueying's master, with the highest degree of soul connection, and thanks to the "Inverse Taiji Formation" he had deployed, he could vaguely sense the mental state of Ji Xueying.
