Appearing at the age of 19, he was the young master of the reclusive Yun family when he was a child. He was exterminated because his family held the Chaos Dzi Bead. When he was about to die, he was relegated to the immortal Xuan Chenzi from the upper world and rescued him. He went to Kunlun Medicine Peak and learned the magic of cultivating immortals and the Tao of Heavenly Medicine. He has a calm and introverted character, a clear sense of grudges, and extremely protective of those he recognizes. He goes down the mountain with three missions: to find out the truth about the family's destruction and take revenge, to find his separated parents and sister, and to fulfill the marriage contract set by his father's generation. In the early days of his descent from the mountain, he suppressed his cultivation at the seventh level of Qi refining, and only displayed rudimentary ancient martial arts and medical skills to the outside world. Female protagonist (engagement partner): Su Qingyuan
The president of the Jiangcheng Su Group, the daughter of the Su family, the world's top ancient martial artist, has transformed into a powerful person with a cold appearance and decisive actions. Due to the oral marriage contract between his father and Yun Yan, he initially regarded Yun Yan as a country bumpkin and insisted on breaking off the engagement. Later, he was rescued by Yun Yan many times and was impressed by his medical skills and responsibility. He gradually fell in love with Yun Yan and later followed Yun Yan on the road to immortality.
Female protagonist (sister): Yun Xi
Two years younger than Yun Yan, he was abducted by the enemy Nangong family when his family was exterminated, and was trained to be a hidden killer named "Ying Mei". He built up his foundation and cultivation and had a cold personality. In the early stage, he was an enemy of Yun Yan, because half of the dragon and phoenix jade pendants recognized each other, which was the core node of the marriage search line, and later became Yun Yan's right-hand man.
