Bai Xiaowen was talking about Zhang Zhongjing.
After Zhang Zhongjing cured Cao Cao's four sons of Blood-Sepsis Worm Poison, Cao Cao kept him at the Xudu post station.
After Bai Xiaowen occupied Xudu and pacified Henan, Zhang Zhongjing had repeatedly sent people to request his freedom so he could go to Lingnan and write books, but Bai Xiaowen never responded.
Bai Xiaowen was also somewhat reluctant to let him go.
Although Zhang Zhongjing was barely mentioned in Romance of the Three Kingdoms, he was immensely famous in history and had been widely renowned for generations!
Therefore, his medical skills should not have been much inferior to Hua Tuo's. The fact that he could cure Cao Pi and the other three was proof enough.
The White Phoenix Team itself did not really need a doctor, but if any of the native generals under Bai Xiaowen suffered Severe Injury, having Zhang Zhongjing around would at least ensure they survived.
Thus, after Bai Xiaowen ordered people to "invite" Zhang Zhongjing from Xudu to Ye Capital, he never went to see him.
Now that Ge Xuan was about to refine pills to remove the curse on Ma Teng, Bai Xiaowen thought of putting Zhang Zhongjing to use and having him help Ge Xuan restore Ma Teng's health.
Soon, Zhang Zhongjing was brought before Bai Xiaowen.
Bai Xiaowen first used Insight. Sure enough, Zhang Zhongjing was also a Rare Boss, and he possessed a special technique: Medical Sage.
``` [Medical Sage: Passive. Zhang Zhongjing has saved countless lives, and everyone under heaven admires him.
