Although Dong Tianyu had a mixed spirit root, the palace of gold still presented hundreds of different cultivation methods for him to choose from.
With the help of survival points, Dong Tianyu could filter out the methods that didn't match his skillset well. Eventually, he chose a method called 'Chaos Decision'.
This cultivation method had high compatibility. No matter how the spirit root was before cultivation, the methodology would gradually transform any type of spirit root into a chaos spirit root after practice.
Other than that, once the technique was successfully cultivated, it would circulate within the body on its own, constantly absorbing energy from the surrounding air. This energy included, but was not limited to, Spirit Energy.
Due to this special feature, after practicing Chaos Decision, one could become immune to a certain degree of pure energy attacks. Rather than immunity, it would be better to describe it as absorption.
