Previous-life Su Han, after all, was once the Sovereign of the Holy Domain, Ancient Demon Dragon Emperor.
In his possession were not only powerful cultivation techniques but also secret techniques that could turn seas and move mountains at a flick of his wrist; plenty of them made many envious during his lifetime. Even many mighty beings of heaven and earth had once come, at a great cost, to beg Su Han to exchange some techniques with them.
As for the secret techniques within the Holy Domain, Su Han had them, and he also possessed the secret techniques of the lower, middle, and high-grade star domains.
However, the energy consumption required to execute these secret techniques was simply too immense, not just depleting Dragon Power but also the mind and even the Soul Force.
Any powerful secret technique certainly couldn't be constructed merely on Dragon Power; this, Su Han knew deeply.
