For Jiang Chengxuan, the need for celestial energy seemed endless.
It had been a long time since he last entered seclusion for cultivation, and now he felt an almost greedy satisfaction with this familiar sensation.
After breaking through to the Immortal Transformation Realm, Jiang Chengxuan had devoted most of his efforts to the path of alchemy.
Consequently, his transformed immortal body and its meridians and dantian had remained largely undeveloped, waiting to be fully realized.
For most cultivators, developing the power of the immortal body was an extremely lengthy and arduous process.
But for Jiang Chengxuan, who had already spent a millennium in cultivation, everything progressed smoothly.
Under the influence of the pills that enhanced his immortal power, Jiang Chengxuan's body absorbed every bit of celestial energy flowing into his domain, converting it into his own strength.
