Wang Che still remembered that at that time, he was already a Soul Formation mighty figure. He had been in seclusion for more than a thousand years and slowly deduced the follow-up through this remnant piece. As for the difference from the true Primordial Heavenly Technique, Wang Che did not know.
He had never seen it before.
However, it was actually still a little late to switch from the Soul Formation realm to cultivating the Primordial Heavenly Technique. However, after cultivating, from the mid-stage Soul Formation realm to the late-stage Soul Formation realm, there were small achievements. After cultivating the Primordial Sacred Soul during a Dao Enlightenment session, he basically began to dominate the cultivation world at that time.
