The Zhou Family Martial Arts School is shaken when its ancestral Xuan Steel, a material only its founder Zhou Zhengya could move, is punched through. While everyone is stunned, the current head, Zhou Zhengnan, uses this incident to rally his disheartened disciples, vowing to revive the Zhou family's legacy. All of this is witnessed by Zhou Zhengya, who has possessed the cleaner, Auntie Wang. She is pleased to see her great-grandson Zhou Zhengnan's mettle. Meanwhile, the news of a peerless genius emerging from the Zhou family quickly reaches their rival, the Hong Family Martial Arts School. The head, Hong Guodong, and his son, Hong Hao, are greatly alarmed upon hearing this, signaling the imminent eruption of new conflict between the two families.

Hong Guodong, the owner of the Hong family martial arts school, learns of a formidable expert from the rival Zhou family who can punch through steel plates. Driven by greed, he not only intends to poach this talent but also to seize the Zhou family's property. He dispatches his son, Hong Hao, and his men to the Zhou family martial arts school to provoke them. Hong Hao and his entourage arrogantly demand the expert be handed over and threaten to tear down the "Southern Fist Orthodox" plaque, a symbol of the Zhou family's honor. Zhou Zhengnan, the heir of the Zhou family, steps forward, and the tension escalates, with conflict on the brink of eruption. All of this is witnessed by Zhou Zhengya, an ancestor of the Zhou family, who has possessed Aunt Wang, the cleaner.

Hong Guodong, the owner of the Hong family martial arts school, brings his son Hong Hao to the Zhou family martial arts school to provoke them and seize control of the school. Facing the arrogance of the Hong family and the decline of the Zhou family, Zhou Zhengnan, the heir to the Zhou family, vows to defend his ancestral business to the death. Hong Guodong proposes a best-of-three ring match to decide the victor, but the Zhou family members lack confidence. At a critical moment, Aunt Wang, the cleaner of the Zhou family (who is actually the ancestor Zhou Zhengya who time-traveled), steps forward to accept the challenge. The first match is a blindfolded water balloon striking competition, testing sound localization and reaction speed, posing a severe test for the Zhou family.

During the martial arts competition between the Zhou and Hong families, Zhou family's senior disciple Li Zhuang performs poorly in a blindfolded water-ball striking test. Auntie Wang, a cleaner (actually Zhou Zhengya, the Zhou family's founder, possessing her body after time-travel), points out his technical flaws and accurately predicts he will only break twelve. Her prophecy comes true, leaving Zhou family heir Zhou Zhengnan stunned. Subsequently, Hong family disciple Xu Jingxing effortlessly steps up, winning with a score of seventeen, completely humiliating the Zhou family and leaving everyone in shock and shame.

This episode features a crucial martial arts match between the Zhou Family Boxing Gym and the Hong Family Boxing Gym. After suffering a loss in the first round, the Zhou family's morale plummets. Hong Hao, the young master of the Hong family, displays astonishing strength in the second round, hitting twenty targets blindfolded, pushing the Zhou family to the brink of despair. Just as Zhou Zhengnan, the heir of the Zhou family, feels disheartened, Aunt Wang, the cleaner at the gym, suddenly intervenes. She stops him with an extraordinary aura, hinting at her hidden astonishing identity and an upcoming plot twist.

The episode opens with Zhou Zhengya, the founder of the Zhou family, explaining the martial arts philosophies of Southern Boxing and the Zhou family's style: "borrowing force" and "rhythm." The scene shifts to the present day, where Zhou Zhengya, now possessing the body of Aunt Wang, a cleaner, reveals the core principles of the boxing style to her great-grandson, Zhou Zhengnan. This revelation stuns Zhou Zhengnan, who recalls similar teachings from his ancestor in his childhood. At this moment, Hong Hao, the young master of the rival Hong family, makes a disrespectful remark, mocking Aunt Wang and the Zhou family's boxing. A conflict over martial arts dignity is thus ignited.

In the second round of the martial arts duel between the Zhou and Hong families, Zhou Zhengnan, the heir of the Zhou family, under the guidance of his ancestor Zhou Zhengya (possessing Aunt Wang), undertakes a blindfolded target challenge. Relying on his understanding of "rhythm," he successfully hits twenty-one targets, breaking the Hong family's record and tying the score. However, the strength he displays, while impressive, does not match the rumored "one punch through steel" level, raising the suspicions of Hong Guodong, the master of the Hong family dojo. The match enters its decisive round, but the Zhou family faces a crisis with no one available to compete.

This episode depicts the dire crisis facing the Zhou family's martial arts school, which is on the verge of being absorbed by the Hong family's school. Hong Guodong, the master of the Hong family school, personally steps forward and demonstrates his overwhelming strength by hitting forty targets while blindfolded, relying solely on sound to discern their positions. This leaves the Zhou family in despair. Under pressure from the Hong father and son, Zhou Zhengnan, the heir of the Zhou family, is about to sign over the martial arts school. At this critical moment, Aunt Wang (secretly possessed by Zhou Zhengya, an ancestor of the Zhou family), who was always seen as just an ordinary cleaner, steps forward and accepts the challenge for the final round, bringing a glimmer of hope to the Zhou family.

The Zhou family's martial arts school faces provocation from the Hong family, with no one capable of fighting back. In a moment of crisis, Aunt Wang, the cleaner whom everyone looks down upon, steps forward. Despite the Zhou family's dissuasion and the Hong family's mockery, Aunt Wang (actually the Zhou family's founder, Zhou Zhengya, possessed by a transmigrator) defeats Hong Hao, the young master of the Hong family, with her ultimate technique "Inch Punch to the Heart" when he attempts to smash the plaque, revealing her power for the first time. Later, in a blindfolded ball-hitting challenge, she embeds two balls into the wall with astonishing strength without breaking them, completely shocking the audience with her hidden abilities and salvaging the Zhou family's reputation.
