Jiang Cheng

Excessively proud and arrogant since childhood. The events of the past have greatly changed him for the worse, turning him into a sullen and restless man, filled with burning hatred for Wei Wuxian. During their childhood and youth, they went through many trials and were as close as brothers. But ever since Wei Wuxian began practicing the dark arts, they began to drift apart and eventually became enemies. Jiang Cheng is now known as the most merciless executioner of cultivators who follow the Path of Darkness.
Even as a child, Jiang Cheng was hot-tempered, but only on the surface. In fact, behind the aggression and arrogance, there is a Jiang Wanyin who loves his family madly and strives to protect them. He also loves his brother, Wei Wuxian, even though he commits many crazy pranks. Behind the sharp words is hidden care and concern for his brother. This later manifests itself in the relationship between Jin Ling and Jiang Cheng. Jiang Wanyin scolds A-Ling not because he is truly angry with him, but because he wants him to grow up and finally be able to protect himself.
However, Jiang Cheng also had a deep inferiority complex due to his father, Jiang Fengmian. This was precisely because Jiang Fengmian always favored Wei Wuxian but never showed concern for Jiang Wanyin, which made the latter angry and sad. It should be noted that there were constant reminders from his mother that his cultivation level was inferior to Wei Wuxian. As a result, Jiang Cheng felt that his father did not love him, and this remained a sore point even in adulthood.
Jiang Cheng had insight, correctly predicting that society would turn against Wei Wuxian if he continued to protect the remnants of the Wen clan. Often, when choosing between justice and reputation, Jiang Wanyin chooses the latter, which does not make him a bad person. For example, in one arc, Jiang Wanyin tells Wei Wuxian that if he had not stood up for Mian Mian in the cave, his family would still be alive.
