Bai Xiaochun was panting, and his face was ashen. This was his first time unleashing his Live Forever Codex Daoist magic, the Live Forever Lamp. However, he had visualized the process numerous times, and therefore, felt quite proficient in its use. This was one of the things that made the Live Forever Codex so unique: the fact that it could create a peerless Daoist magic based on the individual cultivator .
However, it was difficult to deal with how draining it was. After unleashing it only once, the power of the Live Forever Codex within him had been drained by more than seventy percent!
Cultivation base drainage was not something that the powers of the Undying Codex could help with. The Undying Codex only helped him recover from injuries of the fleshly body. The cultivation base could only be restored by means of breathing exercises or similar means.
