The Son of Zhang Wuji of the Ming Dynasty! Why Is He a Yamen Servant?

I! Zhang Chengyan! The son of Zhang Wuji of the Ming Dynasty! I have unparalleled medical skills, so it shouldn't be surprising that I saved Chang Yuchun, right? Then it shouldn't be a problem if I accidentally rescued Zhu Biao and his son, right? If that's not enough for you, I also rescued Queen Ma and the Crown Princess. This is finally good, right? But why do you want me to be a yamen servant when I want to open a medical clinic? ? It's okay to be a yamen servant, I'll work hard, but why do your people still want to kill me! ? Lao Zhu, you must let me lift the table! Do you think my Nine Yang Magic is just for show? !
