The only way to solve this problem is for Gui Gui to master the Spirit Rule.
However, it doesn't need to comprehend the Weaving Dream Rules like Qiuqiu.
Under the guidance of the Spirit Master, it naturally integrates the dark rules on the mental level with the Spirit Rule, forming a two-system fusion rule, Sin Rules.
The Sin Rules are similar to the Seven Sins Rules of Spirit Master, but differ in essence.
The Seven Sins Rules combine Spirit and Telekinesis systems, a branch derived from Illusion and Reality Rules, said to turn an opponent's evil thoughts into tangible control, pulling them into the Seven Sins Blood Domain where they cannot escape.
On the other hand, Sin Rules are a combination of dark and Spirit systems, inclined to guiding the dark side of the mind, affecting battles by invoking the evil thoughts within opponents.
