Qin Jiangyi transmigrated into the role of Xia Wuju's apprentice. When Jing Ke attempted to assassinate the King of Qin, he threw his medicine chest to save the king.

The First Emperor insisted on keeping him as a personal attendant, and the Great Qin took a sudden turn as its tyrant embarked on a path of health and longevity.
