Before coming to the school, Mrs. Song had already bought a water gun of the same color and model. She had replaced the ordinary water inside with sulfuric acid. Now, all she needed was a way to switch Lu Nannan's water gun with this one. Then, Nannan would surely spray Si Mingjing in the face. Mrs. Song's spirits lifted.
"Fang Jing, you're so clever. Today, I must disfigure Si Mingjing and ensure she dies without a proper burial!"
Mrs. Song observed Lu Nannan for a long time and finally seized an opportunity to switch the water guns without anyone noticing.
Lu Nannan had no idea that the water gun in her hand had turned into a truly lethal weapon.
