The Heavens Annihilation Profound Arts (2)

Ji Yuan was now looking at the second cultivation slip which contained the Heavens Annihilation Force. 

The first line of this Heavens Annihilation Force had already stunned him.

In order to practice the Heavens Annihilation Force, the cultivator must first be one with his profound defense and power. 

That explained why Yang Batian was equally good with both profound defense and power at the same time.

Therefore, this Heavens Annihilation Force was unsuitable for Ji Yuan since he emphasized more on his profound power than anything else, and he had purposely dropped his profound defense on purpose to deliver more punches to his targets and also because he needed more added speed.
