Shi Lan wakes up in a science fiction world where humans have evolved into Beastmen and fertility value is the measure of a female’s worth. She has transmigrated into a cannon fodder character, the original owner who was a useless female with zero fertility and F-level mental power. In the original story, after winning a lottery to marry the Second Prince, the female lead’s followers push her into a swarm of Insectoid Race and she dies with only her head left. Terrified, Shi Lan abandons the lottery right, searches the Star Net for a remote job to escape the plot, and the only offer she receives is the warden position on Black Nether Star, a notorious prison planet. The previous warden, a middle-aged uncle, hands her files covered in red markings, hurriedly boards a departing spaceship, and shouts a warning: never open the prison door. Confused but determined, Shi Lan enters the heavily guarded facility, her comfort soon replaced by unease.The prison is luxuriously decorated like a villa, not a cell, and only five Beastmen are confined here. They are highly powerful individuals on the verge of mental power collapse, forced into their beast forms and treated as “Esteemed Ones.” Shi Lan delivers breakfast to each. Cell No. 1 holds He Hanshi, a majestic white lion and the empire’s most decorated major general with SSS-level mental power, who remains gentle during her visit. Cell No. 2 contains Mu Tangfeng, a proud Bird of Paradise who scoffs at her and locks his screen. Cell No. 3 holds Ye Ming, a silent black panther with eerie green eyes that startle her. Cell No. 4 houses Jiang Xia, a squishy Pallas’s cat who hisses mockingly. Cell No. 5 is Yan Huoshui, a magnificent red fox with nine tails soaking in a hot spring, who speaks in a deep, seductive voice. Shi Lan is charmed by their appearances but sympathizes when she learns that transformation into beast form means the collapse is terminal, and the empire has essentially abandoned them here to die. She returns to her office to study the thick manual but falls asleep.During her nap, a small green mushroom sprouts from her head, slips through the walls, and enters the prison. Meanwhile, He Hanshi’s mental power collapse suddenly worsens; he goes berserk, smashing everything and ramming his body against the protective door until his white fur is soaked in blood. The other prisoners hear the chaos but know the cells are designed to contain them and no rescue will come—they are as good as abandoned. Just as they assume He Hanshi will die, the green mushroom leaps onto his head, burrows inside, and emerges red in color, wobbling unsteadily. Green fluorescence seeps from the mushroom into the white lion’s body, and his crimson eyes gradually clear to blue. Exhausted, He Hanshi collapses unconscious. The mushroom bounces off his head, rolls on the ground, and quickly returns to Shi Lan’s office to merge back into her hair. The other Beastmen notice the sudden calm and sense an inexplicable mental power fluctuation, but none saw clearly what happened. They exchange puzzled words, questioning if someone from the empire intervened or if something else saved him. Shi Lan wakes up unaware of the incident, stretches, and prepares to continue her first day as warden, oblivious to the extraordinary ability that emerged from her while she slept. The story sets a foundation of survival, mystery, and the hidden potential of the transmigrated protagonist.
