Chen Xi was a famous pet blogger on Earth who was struck by a meteor and transported to the Immortal Realm, specifically Beast Island, a place with the thinnest spiritual energy. As a mortal with no spiritual roots, his body could not withstand the ambient immortal energy, leaving him with only a few days to live. Upon arrival, he was met with hostility and contempt from the local immortals, who viewed him as disposable. The situation deteriorated when a Moonlight Celestial Beast, a descendant of a powerful celestial lineage, went on a rampage after being mistreated by the island's inhabitants. Fearing for their lives, the immortals forced Chen Xi to serve as a scapegoat, sending him to feed the beast in hopes that he would die, thereby buying them more time.
Chen Xi, however, possessed a system that rewarded him with popularity points for survival. The system identified the Moonlight Celestial Beast as equivalent to an American Shorthair cat in his original world, capable of eating normal food. Using his expertise as a pet influencer, Chen Xi prepared a fresh fish soup and layered fish dish that captivated the beast. His success shocked the immortals, who watched in disbelief through a water mirror as the usually untamable celestial beast accepted his care. Immortal Wu Yi, the leader of Beast Island, honored his promise and awarded Chen Xi a Xuanshui Pill, a treasure capable of helping immortals break through to a higher cultivation level. Chen Xi, unable to use the pill himself, creatively repurposed it into a toy for the Moonlight Celestial Beast, further endearing himself to the creature while infuriating the immortals who coveted the pill.
The conflict escalated when other immortals, jealous of Chen Xi's success and fearful of his growing influence, attempted to sabotage his efforts by providing spoiled ingredients. Chen Xi anticipated this and used a system reward called the Aura of Disgust, which caused celestial beasts to attack those near him, effectively punishing his enemies. His skills soon attracted the attention of higher authorities in the Immortal Realm, who were interested in his unique beast-taming methods. When a crisis arose involving sick Moonshadow Celestial Beast cubs on Mucheng Cave, the physicians on the island declared them hopeless. Chen Xi was sent to take the blame if the cubs died, but he successfully treated their nasal congestion using simple herbal remedies and proper care, reviving the young beasts.
The Moonlight Celestial Beast, grateful for Chen Xi's help in saving its kin, publicly declared that Chen Xi would serve only their clan from that day forward, forbidding any immortal from commanding him. This declaration elevated Chen Xi's status, placing him under the protection of a powerful celestial lineage. Despite his mortal nature and limited lifespan, Chen Xi's ability to care for celestial beasts using mortal techniques made him an invaluable asset. The story follows his navigation of the treacherous political landscape of Beast Island, where he must balance the gratitude of the celestial beasts with the resentment of the immortals who seek to exploit or eliminate him. As his popularity grows, so does the danger, with higher powers in the Immortal Realm taking notice of his potential threat to their established order.
