An elixir factory line worker dies in the most ridiculous way—and wakes up in the body of an ordinary man. Now he’s the useless son-in-law of a struggling family… with a past full of humiliation.

Lin Han displays his divine power by single-handedly lifting a truck on the street, scaring away the Lin family members who had previously oppressed him. Facing his wife, Xiaoxiao, who has always been devoted to him, kind and gentle, Lin Han recalls the past where the original owner, framed by his stepmother and kicked out of the family, had insulted Xiaoxiao in every possible way. Feeling Xiaoxiao's true affection, the thousand-year-old Immortal Emperor decides to no longer be cold and aloof, and vows to embark on the path of cultivation with his considerate bedside companion, officially recognizing her as his wife.

At the accident scene, he forces his wife, Xiaoxiao, to call him "husband," miraculously repairs a bicycle, and personally gives her a ride home, much to the shock of his attendants. Upon returning to their humble home, faced with a lavish meal prepared by his mother-in-law (abalone, shrimp) and the soup Xiaoxiao painstakingly brewed, the protagonist not only refrains from showing disdain but expresses great satisfaction. He warmly addresses his mother-in-law as "Mom" and invites everyone to eat together, leaving Xiaoxiao and her mother, who have long suffered his mistreatment, in disbelief.

His wife, Xiaoxiao (female lead), suspects Lin Han's actions are aimed at getting money for her father's treatment and produces all their savings. Lin Han not only refuses the money but hands it back to his wife for safekeeping and solemnly promises to provide a good life for the entire family. Just as the atmosphere becomes warm, Lin Han's wealthy birth mother suddenly appears, shattering the peace.

Episode 5 - My Son-In-Law Is An Immortal

This episode centers on a direct confrontation between Lin Han and his malicious stepmother, Qin Jia. Qin Jia visits under the pretense of concern, but harbors ulterior motives, attempting to further her "ruin him" scheme by gifting him membership cards to several casinos, aiming to push Lin Han into complete despair. Lin Han not only publicly exposes Qin Jia's hypocrisy from back then, when she used "teaching math" as an excuse to drag him to mahjong parlors, but also demonstrates his decisiveness after rebirth by ordering her expulsion. However, just as Qin Jia believes Lin Han is merely putting on a show to extort money, Lin Han accepts the membership cards at the last moment, hinting at a plan of his own and setting the stage for future developments.

Episode 6 - My Son-In-Law Is An Immortal

He successfully gains her trust and obtains a large sum of cash. Lin Fan hands the money to his worried wife and then, led by his mother-in-law, goes to see his unconscious father-in-law. Lin Fan skillfully uses his traditional Chinese medicine pulse-taking technique to realize that his father-in-law is not suffering from a common serious illness but "blockages throughout his meridians." He then secretly uses his internal energy (supernatural ability/divine doctor setting) to heal him.

Lin Han, aware that his current body was neglected by the original owner, plans to refine a "Marrow Cleansing Pill" to restore his strength and bring his family into immortal cultivation. While picking up herbs at the pharmacy, Lin Han's mention of ingredients for kidney tonics and aphrodisiacs leads to teasing from the pharmacy assistant and a shy misunderstanding from his wife Xiaoxiao, who wonders if he "wants to buy that kind of medicine."

The pharmacy assistant, who was initially suspicious of the male protagonist, and his wife, who was secretly surprised, are both stunned by this scene.

However, after the young master leaves, the master re-examines the prescription and discovers that the poisons counteract each other, revealing it to be an astonishingly brilliant remedy. He urgently retrieves surveillance footage to find the prescriber. Meanwhile, the young master successfully revives his long-unconscious father-in-law through self-care and elixirs.
