He naturally knew what Traveling Doctor Liu meant, but he was helpless to even interfere in this matter. Not that he wanted to interfere either.
Both Chen Yuan and Nan Hua were stubborn.

This would help preserve his life longer.

But he also knew that it was impossible for him to hope that much when their background would naturally make them clash with each other.
