Ye Feng's gaze quickly fell upon a type of botanical essence called Sleep Flower.
It was a purple flower about the size of a palm, but staring at it for an extended period would induce a dizzy feeling.
According to the information returned from the Land of Inheritance, the primary function of this flower was to enhance the strength of spiritual power.
Ever since confronting Tian Yun in the Small Phoenix Mountain Restricted Area using his spiritual power, Ye Feng had understood the importance of spiritual power, which was no less crucial than his physical body.
After long observations of the Mutated Wolf King and those Mutated Animals with spiritual power, Ye Feng also realized he had an enormous advantage in the area of spiritual power.
That was his ability to quickly replenish spiritual power using his Life Healing Ability.
