William realized that the iron basin's needle was spinning rapidly. He exclaimed, "Is my magnetism reversed?" He checked. "No. Strange, what's wrong?" Why did the iron basin react the moment his sister returned? Could it be that the magnetic field on his sister's body was different from others?
William immediately walked towards Amelia with the metal basin. Then, he realized that the needle had stopped moving again. William frowned. "Strange, is it broken?"
Amelia's face was filled with conflict. "Brother, why don't we forget it…"
William kept adjusting his direction according to the indicator. Finally, he walked towards the window step by step. He was immersed in the calculation of what was wrong with the iron basin and had completely forgotten what it was for. As he walked, he replied to Amelia, "No, I can't let it go. The last step of calculation is to verify… Wait, the indicator isn't moving. It's stopped!"
