The Unseen Master: Who Taught Him Swordplay? - Episodio 5

At a hunting site a group debates recruiting a lone young man for tiger-bone pay as vicious beasts roam. A tiger demon attacks, but despite having no spiritual energy the young man kills it with a single punch, shocking everyone. When scavengers name the tiger's demon core as a way to break cultivation bottlenecks, he surprises them by taking only the tiger bones and leaving the core. Bill and the others read that as a charitable opportunity to advance their realms. The episode closes with someone calling, "Sir, take a look," as all eyes turn to the abandoned core.
