On the screen Xue Xi pointed at, Liu Xiu walked to the staircase and casually supported himself against the wall before continuing downstairs.
The document in his arms did not disappear at all.
Zheng Zhi mocked, "We've seen that. There were no changes to his document bag. It's impossible for him to have passed something there. Moreover, there's no one around that area. I really thought you'd found something. I didn't expect it to be a false alarm…"
Xue Xi clenched her jaw and sighed. She pointed at another screen. "This is the other side of the wall."
The other side of the wall?
On the other side of the wall was Xue Xi's laboratory. There were many people, so the two of them did not notice it. However, Xue Xi pointed at one of them and said, "Look at him."
Upon hearing her words, Jing Fei and Zheng Zhi took a closer look and realized that the person was holding a document in his hands. He quickly put it in his bag and continued walking.
