The episode opens with Zhang Xi (Venerable), a seemingly ordinary man, revealed to be a hidden master. He casually orders a small turtle (Dragon Turtle) to "block the sky," causing the heavens and earth to tremble. This event is witnessed in terror by Imperial Tutor Zhou Changyang and His Majesty the Emperor, who initially mistake it for a new demon king's rampage, only to be shocked by the Venerable's subsequent actions. Meanwhile, the demon princess Bai Jingjing and the Demon King Jiang Taibai also witness this spectacle. Disguising his divine ability "One Thought Changes the Universe" as cooking, the Venerable uses another powerful demon lord (Vermilion Bird Demon King) as an ingredient, defeating and capturing him in a pot with cooking wine and salt. At the end, Bai Jingjing tragically discovers that the slain demon lord is her father, setting the stage for future conflict.

The mysterious "Venerable One," Zhang Xishi, uses powerful magic to "reverse yin and yang," restoring world order and prophesying great chaos to come. Meanwhile, the Venerable One's son, Zhang Lin, unaware of his own destiny, is preparing a "Ten-Ingredient Vermilion Bird Soup" in a mountain cabin. At this moment, the Demon Princess Bai Jingjing and the Demon King Jiang Taibai, disguised as an old servant, arrive, drawn by the aroma. After tasting the soup, Bai Jingjing learns that one of its ingredients is the Demon Lord, and in a fit of rage, she attempts to kill Zhang Lin. In the midst of her attack, a hidden power within Zhang Lin is unleashed, forcing Bai Jingjing back into her original form as a white cat.

To her surprise, she finds him cooking a demon lord into soup and forcing the subdued demon king Jiang Taibai to taste it. In a relaxed atmosphere, Jin Lanyue sternly questions Zhang Xi why he unsealed the demon ancestor. Zhang Xi calmly admits it and reveals his terrifying strength, having reached the "Half-Step Immortal Realm," declaring, "I am invincible below the Immortal Realm." Just then, Zhang Xi's son, Zhang Lin, arrives, revealing his father's identity as a peerless master, setting the stage for future plot developments.

Episode 5 - Grandmaster on the Down-Low

Zhang Lin, a captain in the Demon Slaying Division, returns home to visit his seemingly ordinary father, Old Zhang (Zhang Xi). Old Zhang, in a playful tone, reveals the grave crisis of "the demon ancestor's birth" and expresses doubt about Zhang Lin's position in the Demon Slaying Division. Zhang Lin wants to take his father back to the capital for safety, but is stubbornly refused. During their conversation, Old Zhang mentions the "cat" accompanying Zhang Lin, introducing Bai Jingjing, a demon princess only Zhang Lin can see. Since his father cannot see Bai Jingjing, a series of misunderstandings and comedic interactions unfold, concluding with Old Zhang attempting to check the "cat's" gender, only to be angrily rebuked as a "lecher" by Bai Jingjing.

Episode 6 - Grandmaster on the Down-Low

The plot then shifts to a conflict between Zhang Lin and his father, Zhang Xi. Dissatisfied with his current situation and harboring ambitions of being "below one person and above ten thousand," Zhang Lin, a sixth-rank martial artist, wants to take his father away from what he sees as a "broken place" to the capital. Zhang Xi dismisses this with disdain, retorting by asking when Zhang Lin will reach the ninth rank. After Zhang Lin laments the rarity of ninth-rank experts, Zhang Xi and his companions reveal their true identities as "Venerable," the head of the Demon Slaying Division, the Demon King, and the Demon Princess, leaving Zhang Lin, who thought they were just "playing house," dumbfounded.

Episode 7 - Grandmaster on the Down-Low

This episode revolves around a comedic identity mix-up. Zhang Lin, a captain of the Demon Slaying Division, holding Bai Jingjing, the demon princess sealed into a cat, talks at length about the ferocity of the legendary Demon King Jiang Taibai, unaware that his own father, Zhang Xi, is the Venerable One, and that Jiang Taibai is present. The real Jiang Taibai, disguised as an old servant, is terrified by Zhang Lin's boasts and awkwardly tries to "disprove" them, claiming to be a vegetarian. Zhang Lin, disbelieving, escalates his bragging, claiming to have fought Jiang Taibai for three hundred rounds, creating a comical scene. Ultimately, Jiang Taibai breaks down and begs for mercy, fearing that Zhang Lin's descriptions will anger the Venerable One present.

Episode 8 - Grandmaster on the Down-Low

Zhang Lin, a captain in the Demon Slaying Division, receives an urgent "flying sword message" ordering him to forcibly escort his seemingly ordinary father, Zhang Xi, to the capital for his protection. However, Jin Lanyue, the head of the Demon Slaying Division, appears and reveals that the urgent order was a ruse to lure Zhang Lin away. Her true intention is to request Zhang Xi—the reclusive "Venerable"—to come out of seclusion and mediate peace talks with the demon race. Although everyone believes peace talks are hopeless because the Venerable "killed" the Vermilion Bird Demon Lord, the Venerable reveals he only sealed the Demon Lord's essence. With the joint pleas of representatives from both the human and demon sides, the Venerable agrees to come out of seclusion, but is then "abducted" to the capital by his subordinates, who are unaware of the true situation and are following the original plan, leading to a comical turn of events.

Episode 9 - Grandmaster on the Down-Low

The reclusive master Zhang Xi (Venerable) decides to return to the mortal world. Before leaving, his disciple, Imperial Tutor Zhou Changyang, returns the token symbolizing the identity of "Human Leader." Zhang Xi, accompanied by the subdued demon king Jiang Taibai disguised as master and servant, heads to the capital. At the city gate, they are stopped by guards for lacking identification and a hefty security deposit. Zhang Xi, dressed plainly, claims his son is a fifth-rank official in the capital, drawing ridicule from bystanders. As the confrontation with the guards escalates and he is threatened with arrest, Zhang Xi calmly reveals the "Human Leader" token, instantly stunning everyone present.
