This was a trick Yun Qin discovered when she was dealing with Yun Rou and her mother. Every time she remembered events from her previous life and became emotionally unstable, she would become a ghost with a human body.
As expected, after Yun Qin turned into a human-body ghost, she was able to touch her evil energy.
Thus, Yun Qin used her evil energy to form stairs and walked up the tree step by step to the wood house.
Seeing Yun Qin's appearance turn ferocious and terrifying and evil energy was emitting from her body, a few hidden ghosts under the tree was bewildered.
The little black furball, who the other hidden ghosts were watching, also had a conflicted look on its face. With its limited knowledge, it could not explain what was happening to Yun Qin.
Obviously, after discovering that Yun Qin might be a ghost, the hidden ghosts all let out a sigh of relief.
As for Yun Qin, when she entered the treehouse, she was confused.
