2068 Sister Nian Takes Revenge on the Spot Xie Xinyao and her team were in front of the experiment table, taking notes with a ballpoint pen. Her eyes flashed when the girl walked out, as if she was watching a show. Xue Zhu and the rest were watching Cao Yanhua and Han Cheng do the experiment. Hearing this, she quickly walked over and tugged at the girl’s sleeve. She asked softly, “Qiao Nian, what’s wrong? “Aren’t you doing experiments inside? What happened?” Qiao Nian said expressionlessly, “Someone exchanged my potassium permanganate for titanium sulfate.” “What?!” Xue Zhu had helped her prepare for the experiment previously and knew that Qiao Nian’s experiment would take a lot of time. If she failed, she would have to start all over again. Four hours was not four minutes. Wasn’t this a prank? Xue Zhu had mixed feelings. She was worried and anxious. “How could that be? Then, your experiment…” “It’s ruined. I can only do it again,” the girl said calmly, but her expression was cold. In the next second, she said to everyone in the laboratory, “No one is coming out to admit it, right? I just need to check and I’ll know who did it. The reagents here are cleaned and wiped every day. No one’s fingerprints from the day before will be left. “In other words, I only need to send this bottle to the laboratory for examination to find out whose fingerprints are on it other than mine. I’ll look for the laboratory records again and see who didn’t need to use it during the experiment but left their fingerprints on it. Then we’ll know who did it. “This process is not troublesome. It won’t take long.” Qiao Nian’s voice was low and calm, as if she had already seen through everything. Everything was within her control. “I’ll ask again. Who did it?” She was expressionless, but her aura was wild and surly. No one dared to speak loudly. Cao Yanhua and Han Cheng looked at each other and subconsciously looked in Xie Xinyao’s direction. As expected. The two of them realized that Xie Xinyao’s expression had changed slightly. It was obvious that she had something on her mind. Cao Yanhua did not want to blow things up. He walked over and patted the girl’s shoulder. He said in a low voice, “Qiao Nian, why don’t we forget about it?” Xie Xinyao had always been domineering in the Level 8 laboratory. Other than listening to the teacher, she did not care about anyone else. Many people in the laboratory had been ostracized and “pranked” by Xie Xinyao. Back then, when Han Cheng first came in, he was tricked by Xie Xinyao once. Later, Xie Xinyao saw that Han Cheng was close to him and changed her attitude. She kept calling him Senior Han from then on. This time, it was obvious that Xie Xinyao had done this to Qiao Nian. After all, Qiao Nian did not give Xie Xinyao face last time and embarrassed her in public. “You don’t have to rush to give me the experimental data. I’ll tell the teacher. You can give it to me the day after tomorrow.” Cao Yanhua still wanted to make peace. Qiao Nian frowned, her eyes filled with ice. She pursed her lips and walked to the experiment table. Under everyone’s incredulous gazes, she poured an entire bottle of titanium sulfate into Xie Xinyao and the others’ test tubes. White smoke immediately came out of the test tubes. Amidst the exclamations… The test tube used by Xie Xinyao and the others exploded! “Ah.” Xie Xinyao did not have time to dodge, and chemical reagents were splashed all over her clothes and arms. She immediately shouted in a sorry state, “Qiao Nian, are you crazy!”
