Yang Yu never liked to waste Skill Points. When learning "Shadow Deception," he also acquired a prerequisite skill called "Shadow Power."
This Skill's effect was to extract some Magic Power from oneself and create an illusion identical to oneself.
In the Ancient Martial Arts Sect known as Shadow Stream, this shadow, which closely resembles the person, was an essential Skill for initiating most attacks.
Unfortunately, this skill itself had no attack power and could only take someone by surprise at best, much like just now.
The shadow replicated by "Shadow Power" was predominantly black, and as long as one wasn't blind, they would know it was a fake body.
It only worked best when completely dressed in black or in the pitch-dark environment where one couldn't see their own hands.
Scenes like this in full black were really hard to come by.
