Master had given Youmei a task. It was the first task he had given Youmei that took her away from him. He was trusting Youmei with this task, and Youmei was going to do her best to deliver.
Her task involved following Liang Wei. Master believed he knew the location of the kidnapped girls. That meant she had to wait for him to show up, then follow him after he left.
She was hiding within the shadows, darkness engulfing her. Youmei heard people say the darkness was scary, but she didn’t think so--it was comforting and warm. Anyway, this realm of shadows was pure black, but she could still see everything happening outside of the shadow. That was how she noticed Liang Wei as he emerged from the base with several other people.
Youmei didn’t know who the other people were. She counted five. They didn’t smell very strong and she couldn’t sense their cultivation. They were normal people.
