Mo Ran is a disciple Sisheng Peak. He lives as a young master of the sect, the nephew of sect leader Xue Zhengyong and Wang Chuqing and cousin to Xue Meng. He is the disciple of Chu Wanning. In the beginning of the novel, Mo Ran was the first emperor of the cultivation world, Taxian-jun. After over a decade of rule, he committed suicide; unexpectedly, he wakes up in the past, the same year he turned sixteen and joined Sisheng Peak. Mo Ran was a good looking youth, often wearing Sisheng Peak blue, though he did not wear the silver-blue light armor. His eyes are "clear black that were gentle with a hint of purple. Warm and comfortable and somewhat lazy." Taxian-jun was still handsome, but unnaturally pale with a manic look in his eyes. His eyes seemed to have a sinister purple cast to them.[3] He was always dressed in black robes with golden threads and a "maim", a beaded crown worn by ancient Chinese emperors.[4] Mo Ran is described as very attractive. He has dimples on his cheeks, sparkling eyes, and naturally upturned lip corners making it appear as if he is always smiling. In his past life Mo Ran Mo Ran (墨燃, Mò Rán) is a disciple Sisheng Peak. He lives as a young master of the sect, the nephew of sect leader Xue Zhengyong and Wang Chuqing and cousin to Xue Meng. He is the disciple of Chu Wanning. In the beginning of the novel, Mo Ran was the first emperor of the cultivation world, Taxian-jun. After over a decade of rule, he committed suicide; unexpectedly, he wakes up in the past, the same year he turned sixteen and first joined Sisheng Peak. Early Life Mo Ran was a good looking youth, often wearing Sisheng Peak blue, though he did not wear the silver-blue light armor. His eyes are "clear black that were gentle with a hint of purple. Warm and comfortable and somewhat lazy."[1] "[...] he was good looking. The curve of his nose gentle and soft, his lips thin and dewy, his appearance naturally radiating notes of kindness and sweetness. Just by looking at his face, anyone would think he was a lovable, good person."[2] Mo Ran is described as very attractive. He has dimples on his cheeks, sparkling eyes, and naturally upturned lip corners making it appear as if he is always smiling. Current Lifetime At twenty-two years old, Mo Ran is described to be 3 cm taller (189 cm vs 186 cm) than in his first life. The difference is due to being more physically active in this lifetime during his teenage years instead of locking himself up in a room. He is also tanned and more muscular (though still lean) from regular outdoor labor. During the five years of Chu Wanning's revival, he takes to wearing black robes. Mo Ran past life As Taxian-jun, he was tyrannical, cruel, violent, and merciless. However, he wasn't too bright and was rather uneducated as he rarely listened to Chu Wanning's lectures and lessons.[3] The emperor was prone to anger and showing signs of madness as time passed. He would reward and punish in extremes. When someone has been kind to him, he was endlessly loyal, such as him carrying his deep feelings for Shi Mei well into his second life. Conversely, he was sadistic and cruel to those whom he felt had wronged him. Taxian-jun also had low emotional intelligence and lacked general insights into his own emotions, he often behaved in ways that were contrary to his words and acted ambivalently towards Chu Wanning whom he has always had complicated feelings for. Mo rna current life Immediately after his rebirth, he was relatively more forgiving. He decided to avoid making the same mistakes he did in the past lifetime.[6] He still had a thick face (no shame) and was arrogant. He loathed righteous people who rush to always help others with the smallest problems.[7] He was confident, mischievous and cheeky.[8] He was sweet to the people he cherishes and likes to act spoiled in front of them.[9] During this time, Mo Ran began to feel regrets over his harsh actions towards Chu Wanning and didn't like to recall the times when he mistreated Chu Wanning in their past life, as he found himself increasingly bewildered over the irrationality and brutality of his past behaviors. In the previous timeline, he did not pay attention during classes and was rather uneducated so after being reborn, he decided to get some basic knowledge by listening Chu Wanning's teachings. He still had many of his negative qualities and instincts from his time as Taxian-jun, but he would temper his actions mostly out of necessity. At this time, his strength had not been fully developed as yet, and he was not as powerful as when he was at the time of his death.

He presents himself as kind-hearted, polite and wanting to reason with people instead of fighting. He has a sweet temper and doesn't hold grudges. When Mo Ran and Xue Meng argue, he tries to calm them down and is the mediator.

Chu Wanning is extremely righteous and believes strongly in putting the welfare of the people before his own desires and personal relationships, with his disciple Mo Ran in their previous life. He believes in upholding justice and fairness, and that no one is above the rules and punishment.
