Chen Yu's Title Skill, Soul Code, was not like Li Changhe's Hundred-Headed Shooter, which possessed obvious offensive capabilities.
But its auxiliary effect was first-class; its strong psychological suggestion could make the opponent develop hostility or goodwill towards her in a short time. Although the duration was not long, the intensity of the psychological suggestion was very high.

If the opponent was deeply affected, they would chase after her recklessly, trying to kill her. In doing so, they would also be lured into an encirclement. That's exactly what Chen Yu did in the Great Tang, where she trapped and killed many Chaos Warriors and servants.
The latter, on the other hand, was very suitable for gathering intelligence in such unfamiliar environments without raising any suspicions.
