The director of the hospital, Cao An, traveled through the Three Kingdoms to become Cao Cao's long-lost eldest son. He was adopted by his master Hua Tuo from an early age and named Hua An. He studied medicine for eighteen years and awakened the "Ji Shi System Mall". At the beginning, Cao Cao suffered from a head wind. All the doctors in Yanzhou could not cure it, and the imperial ministers were helpless. So he posted a list and offered a reward of ten thousand gold to anyone who could cure Cao Cao. Hua An passed by, for his own better life, and hugged Boss Cao's thick thigh, uncovered the list, and saved Cao Cao. Because he carried a dagger made of iron wood - the Dragon Slaying Dagger, his identity was directly exposed by Mrs. Ding.
