I can control a spirit

Hua Tianshu was surely planning to head out to the demon realm but he wasn't going there in search of the master of curses, he was going there in search of the fake 'art of controlling spirits' cultivation manual. 

The spy nodded his head. Although he was still confused, when being threatened by Hua Tianshu, he didn't really have a choice of asking questions or refusing to comply. 

"I don't expect much from you but if you can, try to find the identity of the demon that is threatening you." 

The man gulped as he heard this and muttered, "He's a demon... Can they really be differentiated?" 

Hua Tianshu smirked as he heard this question. Most people didn't distinguish demons from one another. As long as they were a demon, they were considered evil and needed to be killed or feared. Previously, even Hua Tianshu shared the same thoughts but now, he could no longer say the same.
