Ancient nine-tailed fox Tu Shanrao guarded the Changbaishan barrier for a millennium. Severely injured due to Taotie breaking the barrier, she mistakenly borrowed Huo Yunzheng's pure yang energy to prolong her life. Five years later, she brought the genius cute baby Xiaobao onto a green-skin train to find her husband. Originally intending to entrust the child to his biological father, she was held responsible to the end by Huo Yunzheng. From then on, the sickly sister-in-law settled in the dependents compound with a full compound of ancient great demon relatives, fighting traffickers, curing toxic people, gathering herbs and making money, stirring up a sweet and satisfying daily life in the dependents compound.
