serious illness. Not wishing to admit his mistake, which could have cost him his promotion, Do-ji decided to assign the prince to Hur Jun and let him take the blame. However, Hur Jun successfully treated the prince, for which the grateful King promoted Hur Jun to 3rd grade officer and Chief Imperial Doctor. A war soon broke out as the Japanese invaded Joseon. Hur Jun was credited for saving all the medical annals when the imperial court went into exile, and for reorganizing the Imperial Medical Annals after the war was over, for which Seonjo promoted him to first grade officer. A few years later, Hur Jun recommended to Seonjo to make all the Imperial Medical Annals available to the public, in an effort to make sure that all Joseon citizens could prevent illnesses before they happen. Later, an imperial battle between Prince Yeongchang and Prince Gwanghaegun began, and at first, Hur Jun refused to participate, reasoning that doctors should only treat patients and not get involved in politics. The conflict was ultimately won by Gwanghaegun, who ascended to the throne after Seonjo's death in 1608. Once installed as King, Gwanghaegun immediately branded Hur Jun a traitor since the law stated that if the king were to die of illness, the Chief Imperial Doctor would be responsible. However, Gwanghaegun thought that Hur Jun was a respectable doctor who had a lot of accomplishments including saving the queen's life, but since he could not go against the law, he lightened the punishment, and sentenced Hur Jun to exile in the Southern part of the country. In the south, Hur Jun, with the help of imperial doctors who smuggled medical books to him, published a medical book, Dongui Bogam (Mirror of Eastern Medicine), in 1610; it is considered a classic among Oriental medicine literature. In 1611, Gwanghaegun issued an imperial pardon to Hur Jun, and ordered him to return to the palace. This time, Hur Jun refused, and returned to his hometown to treat patients. At this time, a national plague epidemic began, and Hur Jun was called back to the Imperial Hospital to research a cure. The research was successful, but exhausted Hur Jun, who unknowingly contracted the plague himself and died in 1615, amid national mourning.
