Yu Ren is the Senior Brother of Chen Changsheng, being three and a half years older than him. They are both under the tutelage of Daoist Ji and both lived their younger years in Xi Ning Village reading and memorizing the scriptures of the Great Dao.
He was blind in one eye and missing one ear. His legs were somewhat lame and he only had one hand which was covered in scars. He was also mute.
Chen Changsheng describes his Senior Brother as the most fearless person he knows. At about three years old, despite being a handicapped child, he tried protecting the infant Chen Changsheng from the Golden Dragon.
- He and Chen Changsheng both touched upon the Dragon Language while they were learning about the Great Dao in Xi Ning Village.
As early as three years old, he had a sword hanging on his waist. Later on, he gave that sword to Chen Changsheng before he went to the capital.
