The Founder of Diabolism

For many years, cultivation clans had failed to summon the Yiling Patriarch Wei Wuxian, whom was believed to be killed by his brother Jiang Cheng. However, he is finally incarnated into the body of Mo Xuanyu through a sacrificial ritual, who was a young man full of hatred for his abusive family members. While Wei Wuxian carries on to exact revenge on the Mo Family as per request, he meets the new generation of the Lan sect and finds himself in a zombie mystery. When the situation is deemed too difficult to be defeated alone, Lan Sizhui and Lan Jingyi call for help from any nearby seniors, ultimately attracting the attention of Wei Wuxian's long-time acquaintance.

After Lan Wangji successfully stops the mysterious arm, Wei Wuxian escapes to prevent being spotted by him. He arrives at the nearby Mt. Dafan and meets another young disciple, Jin Ling from the Jin sect. The two have a heated argument which causes Jiang Cheng to come by. Wei Wuxian then learns that Jin Ling is the nephew of Jiang Cheng, whom was left orphaned because of Wei Wuxian's past mistakes. Due to being in Mo Xuanyu's body, Jiang Cheng was unable to recognise Wei Wuxian until the latter starts using his demonic abilities to save everyone from the escaped arm, which summons the Ghost General Wen Ning. While he suspects Wei Wuxian, the latter plays dumb and acts as the notorious cut-sleeve Mo Xuanyu to prevent his cover from being blown. As Lan Wangji also has the same suspicion, he protects Wei Wuxian and even offers to take him back to Gusu when Wei Wuxian speaks of his liking for him, catching Wei Wuxian by surprise. At the end of the episode, the timeline changes to twenty years ago, starting the flashbacks of Wei Wuxian's teenage years.

Wei Wuxian, Jiang Cheng, and their friend Nie Huaisang, start their education in the prestigious Cloud Recesses to become better cultivators. They meet the top disciple Lan Wangji, whom Wei Wuxian confessed he had angered upon his arrival in Gusu. Due to Wei Wuxian's playfulness, he broke three rules during his first encounter with Lan WangJi, and thus is resented by both the latter and the teacher Lan Qiren. However, despite his mischief, he is shown to be a knowledgeable student, although his solutions involve the use of the forbidden demonic path. He is then punished to copy passages in the Library Pavilion and to be supervised by Lan Wangji, much to Wei Wuxian's dismay as he does not chat with him. One month later, Wei Wuxian finishes the punishment and draws a portrait of Lan Wangji as a farewell gift. But this is just another of his pranks as Lan Wangji was drawn femininely. Wei Wuxian also replaces Lan Wangji's poetry book with an erotic art book, causing a fight to break out in the library as Wei Wuxian teases him continuously.
