Concealing the dagger inside the map scroll, Jing Ke and Qin Wuyang represented the Yan and met with the King.Qin Wuyang reportedly became so nervous that he acted almost paralyzed when entering the presence of the King. Jing Ke explained that his partner had never set eyes on the Son of Heaven.
When the King opened the map, Jing Ke immediately seized the revealed dagger and attacked the King, who managed to back away from the initial thrust, tearing off a sleeve in the process.
While the King fled from his attacker on foot, he attempted to draw his own sword hanging from his belt, but was unable to do so quickly enough, as it was a ceremonial sword that had deliberately been made very long.
None of the other Qin officials within the vicinity were armed and able to stop Jing Ke, and the guards stationed outside the palace were unable to reach the scene in time.
In the confusion Jing Ke began to close in on the King, who struggled to get away from the assassin by circling behind a pillar.
Seeing the king in grave danger, a royal physician named Xia Wuju (夏無且) grabbed his medicine bag and threw it towards Jing Ke.
This slowed down the assassin just enough to allow the king to recover some distance. Reminded by cries from other officials, the King managed to shift the sword behind his back and unsheathe over his shoulder.
He immediately struck Jing Ke in the thigh, effectively immobilizing him.Jing Ke, out of a desperate last attempt, threw his dagger towards the King only to miss the target.
The King then proceeded to stab Jing Ke eight more times, mortally wounding him.
At this point, the guards arrived to finish off both Jing Ke and the fleeing Qin Wuyang.
