Ji Ping’s Failed Attempt to Poison Cao Cao

Ji Ping’s failed attempt to poison Cao Cao turns a concealed Han loyalist conspiracy into an open confrontation between a physician with access to the prime minister and a ruler who already knows of the plot. Ji Ping’s betrayal is exposed, but his refusal to identify his co-conspirators leaves Cao Cao to pursue them by other means.

Conspiracy Exposed

After Xuande has left the capital, Dong Cheng and the remaining conspirators continue meeting, increasingly distressed by Cao Cao’s arrogance. One night, after drinking with his friend Ji Ping, Dong Cheng dreams that they have succeeded in killing Cao Cao. He wakes in alarm still speaking of the murder, only to discover that Ji Ping has heard him.

Ji Ping asks directly whether Dong Cheng truly intends to kill Cao Cao. Dong Cheng fears that he will be betrayed, but Ji Ping says that he too wants to remove Cao Cao as a loyal servant of the Han, even at the cost of his clan. To demonstrate his resolve, Ji Ping bites off the tip of one finger. Dong Cheng then shows him the emperor’s edict, confirming the conspiracy’s political purpose and drawing Ji Ping into it.

The Poisoning Attempt

Ji Ping’s position as Cao Cao’s physician gives him a means to act: he treats Cao Cao when the prime minister suffers crippling migraines. Ji Ping says he will poison Cao Cao the next time he is summoned. But before that plan can succeed, Dong Cheng’s abused slave, Qin Qingtong, escapes and reports the assassination plot to Cao Cao, including Ji Ping’s intended method.

The next day, Cao Cao claims to have a migraine and summons Ji Ping. Ji Ping arrives with poison to add to the usual medicine, believing that the summons gives him the opportunity to end Cao Cao’s rule. Cao Cao instead invokes the expectation that a servant should test medicine for his master, calling Ji Ping both servant and son and telling him to drink first. The demand makes clear that Cao Cao knows what the medicine contains.

Ji Ping realizes he has been discovered and tries to force the poison on Cao Cao. Cao Cao overpowers him; the medicine spills onto the floor, and guards seize the physician. The attempted poisoning has failed, and Cao Cao now controls both the prisoner and the public account of what happened.

Interrogation and Death

Cao Cao orders Ji Ping tortured and offers to release him if he names the others involved. Ji Ping insists that he acted alone. Even under severe punishment, he does not disclose the co-conspirators, and Cao Cao eventually stops the torture rather than kill him, intending to use him later.

At a feast for his officials the next day, Cao Cao has Ji Ping brought before the assembled company and announces that he was part of a plot against the court and the prime minister. Dong Cheng is absent, saying he is unwell; the other conspirators are present. Cao Cao again demands that Ji Ping name the instigator, and Ji Ping again claims sole responsibility.

Cao Cao points out that Ji Ping has lost a fingertip. Ji Ping identifies it as proof of his commitment to killing Cao Cao, after which Cao Cao cuts off the remaining fingers on his hands. When Cao Cao orders that Ji Ping’s tongue be cut out, Ji Ping appears to yield and asks to be released from his bonds so that he can tell everything. Once freed, however, he turns toward the imperial palace, says that it is Heaven’s will that he not succeed, and kills himself by striking his head against the stone steps.

Consequences and Significance

The attempt fails both as an assassination and as an interrogation: Cao Cao survives, exposes Ji Ping before his officials, and obtains no names from the physician. Ji Ping’s death ends his own role in the plot without resolving the danger to the remaining conspirators. The episode’s central reversal is the gap between Ji Ping’s belief that his medical access gives him the advantage and Cao Cao’s prior knowledge, which transforms a private act of poisoning into a controlled public reckoning.

Cao Cao orders Ji Ping tortured and offers to release him if he names the others involved. Ji Ping insists that he acted alone. Although Cao Cao continues the interrogation despite the severity of the punishment, Ji Ping does not disclose his co-conspirators. Cao Cao eventually stops the torture, in part because he intends to use Ji Ping later.

The next day Cao Cao holds a feast for his officials and has Ji Ping brought before them. Dong Cheng is absent, saying he is unwell, while the other conspirators attend. Cao Cao again demands that Ji Ping identify the instigator; Ji Ping again claims sole responsibility. By presenting the prisoner to the assembled officials, Cao Cao turns a failed private assassination into a public accusation against the plotters.

Cao Cao notices that Ji Ping has lost the tip of a finger and asks why. Ji Ping says it marks his commitment to killing Cao Cao. Cao Cao then cuts off Ji Ping’s remaining fingers. When Cao Cao orders that Ji Ping’s tongue be cut out, Ji Ping appears to relent and asks to be released from his bonds so he can tell everything. Once freed, he turns toward the imperial palace, declares that it is Heaven’s will that he not succeed, and dies by striking his head against the stone steps.

Death and Unresolved Consequences

Once freed from his bonds, Ji Ping turns toward the imperial palace and declares that it is Heaven’s will that he should not succeed. He then dies by striking his head against the stone steps. His final words frame the failed assassination as a defeat ordained beyond human control, while his death keeps the identities of the other conspirators undisclosed. Cao Cao has survived and publicly exposed the plot, but Ji Ping’s silence leaves the conspiracy unresolved.
