Because the story he wrote was unfinished, Ye Zhiyun was forced to help stabilize the plot, monitor the villain, and prevent the villain from becoming too powerful and threatening the protagonist.
The system gave him three forms - long sword, spiritual beast, and human to complete the plot.
As Ye Zhiyun got along with Yu Heng, Ye Zhiyun became more and more intolerable to the villain's situation and consequences, and became increasingly unacceptable to the system and mission's differential treatment requirements for the villain and the protagonist. Ye Zhiyun gradually became rebellious, becoming a partial villain who changed his ways within the requirements of the system and the plot.
At the beginning, Ye Zhiyun didn't know that the villain in his youth had turned dark. He had already died once, and he had already fallen into the abyss...
Yu Heng was very cautious at first, and noticed Ye Zhiyun's weirdness, and wanted to grasp it secretly. The more they got along with him, the more he discovered what was good and unique about Ye Zhiyun, and he became more and more frightened and uneasy about the feeling of not being able to grasp it.
Yu Heng's hand stopped on Ye Zhiyun's neck, his dark eyes lowered: "Sometimes I think, I can just pinch it off, which saves me so much trouble."
Ye Zhiyun raised his eyebrows indifferently and laughed loudly: "Hahahahaha, you can get it, but you can't bear it."
