บท 1985: The Tenth Disciple

Why?

Because they were all very familiar with this name and knew that Traveling Doctor Liu usually asked his disciples to prioritize saving people. They knew that some people might want to make use of their connection to Traveling Doctor Liu to come to Princess Luo Qing Wei.

Thus, Shi Long Kingdom didn't let those who knew about this matter spread it. 

Those who dared to spread it will be dealt with. 

But who was Feng Qing Lan?

He was not affiliated with Shi Long Kingdom personally. He came from small city and didn't work for the official hospital for Shi Long Kingdom. So even if he spread this matter, Shi Long Kingdom couldn't really do anything to him unless they wanted to make enemies out of Traveling Doctor Liu.
