Chi Jiao didn't feel like she was making a mountain out of a molehill.
As a psychic Esper, she needed to maintain calm at all times.
Only when she was absolutely calm could she ensure that she wouldn't make any mistakes and drag her companions down, as well as perfectly bring out her best state.
As a member of 117, she knew that most of the so-called supernatural events could be explained by magnetic field changes.
Take the haunted house in front of her, for example. Ignoring everything else, the magnetic field here was extremely strange.
Chi Jiao didn't believe that there were ghosts in this world, but she believed that someone was deliberately mystifying this place.
On the other hand, Wan Yingtao had successfully fired up the atmosphere after finishing her ghost story.
