Three-and-a-half-year-old Yan Dudu, under the order of master Yan Lingxi, descends the mountain to find five senior sisters separated for a thousand years and bring them back to the mountain to attend the master's wedding banquet. Outwardly he looks like an ordinary mortal child, but in reality he bears an archaic physical body and shoulders the remnant soul of the Pangu Axe. Remembering the master's instruction "do things gently when encountering matters," he always inadvertently stirs up heaven-shaking storms. Passing through places like the Xuanbing Palace, Wandu Sect, Jiuyuan Market, and Tianfu Pavilion, Dudu uses divine elixir candied haws and a peerless brute strength to continuously shock experts and mighty figures of all factions, successively finding several powerful senior sisters. As accident after accident occurs, the sealed ancient power within his body also gradually awakens.
