Eventually, Ren Xiaosu abandoned the idea of using Yan Liuyuan to test out his new power due to safety concerns. After all, he still could not control the power all that well. What if something happened to Yan Liuyuan when he went through the Shadow Door?
However, Ren Xiaosu thought of another idea. When he copied the Shadow Door from Luo Xinyu, the door stood at almost two meters tall.
But since Ren Xiaosu could only get one arm through it, why would he need to open such a large door? Moreover, it would attract other people's attention too easily. As such, Ren Xiaosu wondered if he could make the door smaller so it would be just enough for him to put one arm through.
When he thought of that, Yan Liuyuan, who was next to him, saw the Shadow Door reappear on the ceiling and start swaying. It was as though some kind of law were resisting Ren Xiaosu's will.
