The Secret Realm Was Far Too Dangerous. In the abandoned Palace.
Lu Xuan's figure was like a fleeting gleam, sweeping past at top speed.
Back in the Medicine Garden, he had already sensed that something was slightly off about this Secret Realm.
From the information on the mutated Spirit Seed, he had learned that the fifth-grade Longevity Peach had been eroded and affected by an evil aura over a long period, thereby mutating into a Mutated Longevity Peach.
That meant there was an evil existence within the Secret Realm, and its aura was anything but ordinary.
