Dr. Li tells the two physicians that the medicine is an "exceedy shake head" from the king, and that even if the herb is poisoned, the king's highness will not be able to resist it. He tells them to get ready for battle, because the enemy has just attacked a neighboring country. The doctor tells them that the news of the prince's death has reached the royal palace, and a civil official has reported that he had poisoned the royal's food with the herb, and wanted to join the enemy forces to kill the prince. The medicine is useless, he tells them, since the king has already given it to him.
