Shi Yuansi at this moment fully understood his senior brother's mad and unstable behavior: Origin fragments! It is regarded by major planes as the supreme artifact for extra advancement and power enhancement! Putting aside how Pei Yan obtained so many fragments, just his method of using the origin fragments is utterly unheard of!
In the Daoist Realm, anyone who acquires the Dao Heart Stone would seek a place rich in Spiritual Qi, which is both safe and secluded, to focus and absorb it slowly, fearing that their understanding of its laws is insufficient and they miss the opportunity, also fearing the greed for power could harm their meridians and lead to demonic possession. The entire process is like walking on thin ice with extreme caution. Who would dare to consume like Pei Yan who swallows several pieces as if they were candy!
