The koi fish demon Li Jin failed to leap over the Dragon Gate and was reborn in a future interstellar era devoid of any religious beliefs, awakening a "Rising from the Ashes" system. Imperial Admiral Jin Lin is on the brink of death, and someone suggests taking a bride for a life-prolonging ritual. Due to their compatible astrological signs, Li Jin is chosen. Upon awakening, Li Jin discovers not only the loss of all his cultivation but also that he is being forced into a political marriage. Fortunately, his future husband is on the verge of death, so as long as he accumulates enough virtue points in the system, he can achieve enlightenment once more. Soon, a koi fish goes viral online: "Repost this koi, and within three days, you’ll receive unexpected gains—perhaps your wish will come true!" Netizen A: "Oh my god! I just reposted Mr. Koi, and the civil service exam I failed three times was suddenly passed!" Netizen B: "Ahhh! The person I’ve been secretly in love with confessed to me! Thank you, Mr. Koi!" Netizen C: "I won 200,000 in the lottery! I’m going to thank Mr. Koi in person!" ... As the mission progresses, Li Jin watches his virtue points steadily increase, nearly enough to rebuild his foundation—until he starts feeling reluctant. Jin Lin’s life force weakens, as if death is imminent. The virtue points in hand could save him—but should he? When Jin Lin wakes up, he’s utterly confused: since when did his bathroom have a fish? Suddenly, the fish flips over, transforming into an exquisitely beautiful young man—just as Jin Lin steps out, fully naked, his sculpted physique on full display. Li Jin: "Fortune-telling, exorcisms, demon-slaying, wealth charms—damn it, my husband’s on the brink again! Just how many virtue points will it take to extend his lifespan?!"
