Training

"Arghh! Finally done," Alex thought as he put away the cauldron and the formation plate. The spirit stone behind the formation plate had gone dull after losing all of its Qi. 

He picked it up and threw it away after realizing it was worthless to him now. 

Suddenly, the space shifted around once more. This time, the hole he had been standing on top of was gone. "What the?" Alex thought. "Why is the hole gone? It was there with me the whole night through multiple space shifts."

He wondered if he missed anything and took out the instruction to the formation he had inside his storage. After reading more than what he had last time, he noticed something that he had overlooked that time. 

"Oh, no wonder. It targets Qi signature rather than actual people caught inside. So anything with my Qi signature and a little more around them all gets teleported around randomly."
