Because of Xion, Xu Ao was severely slapped in the face three times in his life:
For the first time, science tycoon Xu Ao never believed in ghosts in the world until he met Xion in the attic of his cousin's old house;
The second time, Xu Ao, who thought he liked girls with thin waists and long legs, discovered that he was actually curvy;
One last time, Theon made him believe in eternity.
People have human nature, ghosts have their own ways, and they go against the yin and yang to find you.
