Lu Xun’s drug tolerance

Lu Xun’s drug tolerance is a medically significant state formed through childhood violence and later revealed during a crisis involving Song Yuner. It explains why a drug that might have incapacitated another person produces no apparent reaction in him, while also turning his body into a record of the kidnapping he survived at the age of twelve.

Origin in Childhood Trauma

Lu Xun traces his resistance to drugs to a kidnapping when he was twelve. The kidnappers consumed various medicines, and he nearly lost his life; afterward, he became resistant to all drugs. He recounts the episode with an unwavering gaze, describing the pain as though it belonged to someone else. The distance in his telling suggests that the event remains unforgettable even though its immediate emotional force has changed with time.

His tolerance is therefore not presented as an abstract physical advantage. It is the lasting consequence of an ordeal in which medication was associated with captivity, poisoning, and the threat of death. The condition preserves the kidnapping within his present body: the past returns not through a separate flashback scene, but through his explanation of why a later drugging cannot control him.

The Failed Drugging

The state becomes crucial when Lu Xun confronts the aftermath of Song Yuner’s attempt to drug him. When Su Xiangwan questions whether he had any response to Song Yuner, he answers fiercely that he had been drugged but had experienced no reaction. He insists that he did not touch her and that he restrained himself, directly rejecting the implication that the encounter had overcome his judgment or fidelity.

Lu Xun also explains that Song Yuner appeared to have Su Xiangwan’s face and voice. The resemblance made the situation dangerous because it placed an apparent double of his wife before him, but her sudden use of his name exposed the deception. His drug tolerance thus operates alongside recognition: the drug cannot disable his body, and the mistaken identity cannot permanently deceive his mind.

His response also reveals the limits of the attempted manipulation. Lu Xun remarks that such methods are unnecessary when used against him and believes Song Yuner should have understood that he is immune to that kind of drug. The failed scheme consequently exposes both his physiological resistance and the weakness of the strategy directed against him.

Bodily Vulnerability and Control

The condition does not make Lu Xun invulnerable. Elsewhere, his physical state is repeatedly shown as precarious: he suffers respiratory illness, is injured, and reacts with alarm when Su Xiangwan collapses with a high fever. He is also visibly injured while rescuing her, with blood still coming from the corner of his mouth. Drug tolerance therefore marks one specific boundary of bodily control rather than granting general immunity to pain, illness, or violence.

That distinction matters to the emotional structure of the narrative. Lu Xun can resist chemical incapacitation, yet he remains deeply affected by threats to Su Xiangwan. When he believes she may be dangerously ill, the warning that he should prepare to identify her body causes his face to turn deathly pale. His body withstands the drug, but his attachment leaves him exposed to fear, urgency, and physical distress.

Relation to Care and Trauma

Lu Xun’s response to danger repeatedly takes the form of physical protection. When Su Xiangwan is frightened and cold, he ignores his own facial wounds, crouches beside her, and embraces her. When she later cries that she is afraid, he holds her and reassures her that he has been there all along. These scenes place his drug tolerance in contrast with his emotional susceptibility: chemical coercion fails, but the possibility of losing the person he loves reaches him immediately.

The condition also complicates the idea of mastery over the body. Lu Xun’s resistance appears powerful in the present, yet its source is a near-fatal experience in which he had almost no control over what was done to him. The capacity that now protects him is inseparable from the violence that created it. His body has converted survival into resistance, but survival has not erased the original wound.

Narrative Significance

Lu Xun’s drug tolerance serves three connected functions. Plotwise, it prevents Song Yuner’s drugging from producing its intended result and helps clarify that he did not willingly betray Su Xiangwan. Character-wise, it gives concrete form to the childhood kidnapping that shaped him, making an old trauma relevant to a later marital and identity crisis. Thematically, it contrasts physical immunity with emotional vulnerability: Lu Xun can resist a substance designed to control him, yet he cannot remain detached when Su Xiangwan is threatened.

The state also turns memory into evidence. His account of the kidnapping corrects the assumptions surrounding the failed drugging, while the survival of the childhood experience within his body shows how the past continues to govern the present. Drug tolerance is consequently both protection and reminder—a practical defense born from catastrophe, and a permanent sign that the catastrophe has never entirely disappeared.
