After Wang Xiaoke was born, he was abandoned by the Wang family in Kyoto and wandered for five years. Fortunately, he met his master and learned the method of cultivating immortals. When he was five years old, he was brought back to the Wang family by his seventh sister Wang Siqi, and since then he has started a happy life with his eight "brother-controlled" sisters. While enjoying the favor of his sisters, he continued to show off his ability to cultivate immortality, shocking everyone. In the end, with the support of his sisters, Wang Xiaoke not only found out the truth about the package swap, but also relied on his own cultivation to protect his family. After uncovering all the "vests", he and his eight sisters lived an urban life full of warmth and fantasy, and wrote an urban fantasy legend in which a cute baby counterattacks with magical powers and the love between siblings is deep.
