Chu Ge definitely wasn't just making things up on the spot; what he said held another meaning, which was to make them develop a mindset that Chu Ge didn't care about them at all.
Long Ang obviously understood Chu Ge's intention and, while feeling a sense of difference in his heart, also felt a bit worried for Chu Ge.
The marvel of the Illusion Technique lies in its ability to entice the mind and disturb one's visual senses, but its drawback is extremely dangerous: once the body is found, the other shadows become mere decorations during attacks.
This is certainly easy for Long Ang to handle, but he doesn't dare to assume the same for Chu Ge; he worries that Chu Ge, using it for the first time, might not match it with the mental method and is prone to reveal flaws.
