The demon subduing Mystic technique took much longer than the Vajra Mystic technique and the six Senses Mystic technique. It took Zhao Hai 64 days to complete it. Now, Zhao Hai could crush a medium-grade magic artifact into pieces. With one punch, he could probably flatten a mountain. This was the use of the demon subduing Mystic technique.
Zhao Hai couldn't help but let out a long breath after successfully cultivating the superstrength devil subduing Mystic technique. To be honest, the profoundness of this Mystic technique had far exceeded Zhao Hai's imagination. If he didn't have the support of a massive amount of power of belief, he wouldn't have been able to cultivate this Mystic technique.
