The protagonist Lin Fan awakens "source power" in the Lin family in Qingyang City. He is regarded as useless because he cannot absorb spiritual energy normally, but he can sense the "rule cracks" at the edge of the realm. The family was wiped out by hostile forces supported by the domain envoys. Lin Fan fled with his ancestral "boundary-breaking talisman". On the way, he met the mysterious girl Su Muyue and gained a preliminary understanding of the existence "outside the domain".
