The evil-looking piece of jewelry turned out to be a protection amulet. The matter had now taken in a completely different path, way beyond what Zhang Heng initially expected.
He thought all along that the series of mishaps befalling Tian Tian's household were related to her paintings, where they seemed to serve as warnings. By using this method, she intended to tell those around her about the impending threats. Unfortunately, no one noticed it. Perhaps, she attempted to tell the people around her, but no one believed her, thinking that these were all mere coincidences.
After therapy, she stopped sharing these paintings until Zhang Heng accidentally discovered them. As for the last picture of her hiding under the bed, the evil eye must have been referring to Zhang Heng, the intruder, and not the guardian talisman. When Zhang Heng bent down and looked under the bed, his eyes appeared before Tian Tian, automatically fulfilling the painting's prophecy.
