In an apocalyptic world where cutting-edge technology is a relic of the past, despite his illness, Xiaosu hunts to get through each day and support his brother Liuyuan, who has a special ability related to luck. However, one day, Xiaosu unlocks a palace that offers quests in return for strength and skills. As he starts to grow while completing the quests, he starts to wonder what the palace actually is and whether he'll be able to bring down the barrier that divides the powerful from the powerless one day with his newfound power.
