The first person to notice the button behaving strangely was Lei Shi. During his patrol, he could always see the button leaving the base at night, dressed entirely in black to blend into the darkness, clearly trying to avoid detection by him.
Although Lei Shi's spiritual power could see far, it had limitations. He couldn't see clearly at night, and there were distance constraints. In the past, the button's attire would have certainly evaded his surveillance, but she didn't realize that Lei Shi had just advanced recently. After Bi Xia's guidance and communication, his spiritual power now had night vision capabilities, and the observation range could change freely according to the strength of spiritual power.
