He Wang's face was pale, and his eyes wandered. "That's because…"
"Because of what?" Qiao Nian crossed her arms and looked at him calmly. Her tone was relaxed and even a little casual.
However, this recklessness was like a densely woven net trapping He Wang. He found it difficult to breathe, and his expression became paler and paler. "Because… Because…"
He could not explain it.
Because he was the culprit in the first place!
He was the mole!
Everyone was stunned by the results, including the original biggest suspect, Li Lei.
Li Lei looked at him in disbelief and said in a high-pitched voice, "You were the one who stuffed the USB drive into my pocket? Why? Aren't we friends?"
He Wang trembled as if stimulated by him. Finally, he lowered his head and sneered. Then, his laughter became louder and louder. He slowly raised his head, his expression now ferocious and distorted as he looked at everyone in the laboratory fiercely.
