Chen Yang, a burned-out corporate worker in his previous life, transmigrates into a sentient mystical stone and is rescued by Yang Guanfeng, the patriarch of a fallen cultivation family. Within his spiritual sea, Chen Yang takes the form of a capybara. With the family burdened by crushing taxes and bullied by powerful clans, Chen Yang voluntarily steps in to help. Using extraordinary spirit-gathering abilities and defensive spells, he secretly supports the Yang family while anticipating dangers through his strategic foresight. The Yang family members undergo a complete transformation, successively repelling nighttime assassin attacks and surviving a once-in-a-century beast tide. In battles over mineral veins and commercial rivalries, they repeatedly gain the upper hand against powerful sects. Finally, Chen Yang uses a blood sacrifice ritual to establish a soul covenant with the entire clan, leading the Yang family to break free from social hierarchy and build an immortal clan unrivaled throughout the ages.
