Han Yao immediately calmed down after he realized that he overreacted. "But what will happen to you if you do it?" he asked, feeling worried again. After what happened to the Purple Old Manor, Han Yao truly regretted it.
Han Yao knows that the Purple Old Manor is very dangerous, way more than the other haunted places that he referred to Su Yu before for Su Yu to explore. But, not only the Purple Old Manor gained quite 'fame' recently, but Han Yao also didn't see any suitable haunted places to refer to Su Yu at that time. They aren't 'good' enough. So, Han Yao finally decided to tell Su Yu about the Purple Old Manor.
