Time Travel To Tang Dynasty

Zhao Chen is who you can refer to as a prolific writer. In fact, he performs magic while penning his words down, and he is well-respected for it. In fact, Zhao Chen believes that no one in the Tang Dynasty can surpass him when it comes to writing. 
The truth is that Zhao Chen has not always been in the Dynasty. In fact, he only got there about a year ago, using the Golden Finger Cheat System to get into the Dynasty. 
It has been his life goal to find the chief doctor of the Dynasty, the same doctor whom Zhao Chen knows can heal his athsma. This athsma has affected Zhao Chen so badly that he can no longer take walks outside the house, so his desperation for a cure is quite understandable. 
When Chen sees that he cannot get through to the doctor easily, he decides to literally cook his way to finding the doctor. 
However, will his mission be accomplished, or does the System which brought him to the Tang Dynasty have other…plans?
