Chen Baishu, known as the Divine Physician Chen, is the most renowned physician in the Great Qi dynasty, famed in textbooks for generations to come. He is the nephew of Chen Yiban's master and the author of the groundbreaking medical text Tasting a Hundred Herbs, which documented his life and works with techniques centuries ahead of his time. Some people speculated he might be a time traveler, but Qi He—being the actual time traveler—knew the truth: Chen Baishu was simply daring yet meticulous, intelligent, and possessed an extraordinary sensitivity to medicine far beyond ordinary people. He is extremely professional and principled, insisting on his rules even to the point of death, which makes him both loved and hated. He despises being treated like a fool and was genuinely angry when he discovered the Situ family had previously approached his master through Chen Yiban while trying to cheat him. He once dared to perform cranial surgery on the female emperor based on Qi He's joking suggestions. He has a peculiar, dramatic personality and was visibly shaken by Situ Qi's awkward attempt at being polite.
