Of course, the method of "Proving Dao with Power" was revered as the strongest Technique in Heaven and Earth, manifesting its fearsome nature only among the Quasi-Saints.
A half-step Quasi-Saint could entirely match a Quasi-Saint who had cut off a Good Corpse, and when facing those Quasi-Saints who had not cut the Good and Evil Corpses, they could easily be invincible and slay them amidst Heaven and Earth.
If Ye Xuan managed to unify spirit and flesh and cultivated his Daluo Immortal Body to Great Success, stepping into the ranks of a Quasi-Saint, even Quasi-Saints who had cut away both Good and Evil Corpses would surely be no match for him.
With the Heavenly Dao Nine Tribulations, each tribulation was a major life-or-death ordeal; if he could survive the first three, he would be completely qualified to challenge the Saints, and even The Three Pure Ones and Nuwa could only hope to tie with Ye Xuan.
