Zhang Xuan, who once accidentally became stupid, was inherited by Master Tai Xuan and practiced both medicine and martial arts, and his IQ recovered. He relied on his medical skills to save lives and heal the wounded, and used force to punish evil and promote good. He punished the bully Niu Youde, the greedy aunt Wu Meili and others. He met confidants such as Pei Xiaoman and Pan Qiaoyun, and jointly founded a pharmaceutical company. From a country boy to a miracle doctor that everyone admires, he breaks prejudices with his strength and writes a counterattack legend.
