Su Jingchen had long thought of a reason for his absence from home for several years.
Upon hearing Su Jingchen's excuse, Yu Xiaolian just felt that Su Jingchen was really desperate.
Because Su Jingchen intended to deceive his father, saying that his old illness had relapsed and was getting worse, possibly nearing the end of his life, he planned to go to the Western Regions to search for Bell Doctors who specialize in respiratory diseases.
Yu Xiaolian knew about Bell Doctors in ancient times, who were folk physicians roaming the world.
In ancient times, some doctors would often carry a medicine chest and shake a bell while going out to treat patients, tirelessly traveling through streets and alleys to help those who were ill. When people heard the sound of the bell, they understood that the doctor had arrived, hence they were known as Bell Doctors.
