Sun Yurong was stunned for a moment, a look of panic flashing in her eyes, and she stammered, "I went to pick it up when I was eating. I'm going out shopping for clothes tomorrow."

"Lunch or dinner?" Ye Qingqing pressed.

Sun Yurong panicked even more, but quickly regained her composure. "I withdrew the money before having dinner."

Qian Manduo shouted, "Who are you trying to fool? You went to eat dinner at 4:30 and came back at 5:00. Even if you walk fast, it takes more than ten minutes to get from the dormitory to the bank. It takes half an hour round trip. How will you have time to eat dinner after you withdraw the money?"

Sun Yurong calmly replied, "I walk fast, of course it won't take me half an hour. It's your short legs that make you walk slowly."

Qian Manduo is not only thin, but also short, less than 155 cm tall. Sun Yurong is also thin, but tall, 165 cm, and has long legs.

But Ye Qingqing didn't believe her nonsense at all. Qian Manduo was indeed short, but she didn't walk slowly. She walked very fast, like a gust of wind.

Although Sun Yurong has long legs, she walks with a wobbly gait, like Lin Daiyu burying flowers. I've never seen her walk fast. How could she possibly do so much in half an hour?

Before Qian Manduo could retort, Sun Yurong shouted at Ye Qingqing, "What do you mean? Why do you keep asking me? I also had a thousand yuan stolen from me. If you want to ask, you should ask Qian Manduo. She's the prime suspect right now."

Ye Qingqing shook her head slightly at Qian Manduo, who wanted to retort. Although Qian Manduo was angry, she shut her mouth, puffed out her cheeks, and glared angrily at Sun Yurong.

"It's too early to say who the real thief is. Everything needs evidence. My suggestion is that we conduct an internal investigation first. If we can find out, that would be great. If we can't find out tonight, we'll have to report to Teacher Shu tomorrow and ask the police to investigate."

Ye Qingqing spoke slowly and deliberately; she already had a prime suspect in mind.

The thief is definitely an insider, and Qian Manduo also seems to be a suspect. Although Ye Qingqing doesn't think Qian Manduo would do such a thing, he was alone in the dormitory for nearly half an hour, so objectively speaking, he is still a suspect.

Besides Qian Manduo, the rest are Lü Ziqun, Dong Siyue, Song Hongye, and Sun Yurong.

However, Lu Ziqun, Dong Siyue, and Song Hongye can definitely be ruled out. Ye Qingqing's main suspect is Sun Yurong.

However, Sun Yurong was very cunning. She staged a whole drama to portray herself as the victim. To accuse her, one would need sufficient evidence.

Moreover, Ye Qingqing was worried that Sun Yurong would frame Ruan Yingzi by putting her money with Qian Manduo, which would leave Qian Manduo with no way to clear his name.

Lu Ziqun nodded vigorously, "That's what I mean too. Let's investigate internally first."

Sun Yurong sneered and said in a shrill voice, "Investigate if you want. I have nothing to hide, so I'm not afraid of ghosts knocking on my door in the middle of the night."

Qian Manduo also shouted, "I'm upright and have nothing to fear, nor am I afraid of being investigated."

"I think we should search first. To be fair, we should search everyone's drawers and beds, starting with mine," Ye Qingqing said as she opened her drawer.

Dong Siyue and Song Hongye also opened their drawers, and Lu Ziqun, after a moment of surprise, also opened hers.

"I think we should ask someone else to help with the check!"

Ye Qingqing asked two female classmates from other dormitories in the class to help check, and Qian Manduo also shouted, "My drawer is unlocked, you guys check mine too."

Qian Manduo's dormitory was just a few rooms away from Ye Qingqing's. When the other two female classmates went to check, Ye Qingqing's heart skipped a beat and she became nervous.
