Gu Yizhe approached the area where dark creatures hurled themselves endlessly against an invisible barrier. Their twisted forms splattered like ink against an invisible barrier. At the base, the splattered mess was continuously dissolving into shadows before reforming to repeat the cycle.
He reached out with one hand, his palm pressing against the invisible surface. Even though he just saw the stretching forest before him, he felt the solid barrier beneath his touch.
An evil smile spread across his face as he pulled back his hand. He then struck forward with immense force. The moment his knuckles made contact, he felt a strange numbness creep up his arm. The energy from his attack spread evenly across the barrier's surface before vanishing completely, absorbed without a trace.
