Cang Mofeng heard that Xiao Ruo wanted to go out of the city to examine those people, and without thinking, he opposed: "You cannot go, I will send Wang Yipeng, he is an expert in diseases like plagues and smallpox. I will have him take several people with him, you cannot leave the palace! Also, immediately have Xiangxiang return!"
Wang Yipeng is an old Imperial Physician in the palace. More than twenty years ago, a major plague broke out in Jianyue City, Cangming Country. The epidemic was severe at that time, and many people in surrounding cities were infected. Wang Yipeng and several other Imperial Physicians were assigned to go to the epidemic area to treat the people. Except for Wang Yipeng, the other Imperial Physicians eventually contracted the plague and passed away. Later, with the joint efforts of Wang Yipeng and a Wandering Doctor, the epidemic was eventually controlled, although the number of people who died from the plague was already countless.
