After reviewing the three secret techniques, Zhou Chun studied the secret formula for cultivating three mutant demon beasts.
The formula recorded three types of mutant demon beasts: the Mutant Thunder Crane, the Mutant Gold-Eyed Mouse, and the Mutant Horned Timber Wolf.
The Mutant Thunder Crane is evolved from the Thunder Crane demon beast, the Mutant Gold-Eyed Mouse from the Seeking Spirit Mouse, and the Mutant Horned Timber Wolf from the Green Light Wolf.
The Thunder Crane is a mid-level demon beast, with a very sparse population. Those that mutate into Thunder Cranes can usually break through to the Third Order.
The Seeking Spirit Mouse is a low-level demon beast with a considerable population. When they evolve into Gold-Eyed Mice, also known as "Treasure-Seeking Gold-Eyed Mice," they can easily break through to the Second Order and possess considerable combat abilities.
