In the middle, Ouyang proposed a bold hypothesis that security guards may have created a false impression of no one committing the crime by building a fake exhibition hall with the same appearance as the exhibition hall and replacing the monitoring system during network maintenance interruptions. He pointed out that if the security guards had premeditated, they could carry out theft in a fake exhibition hall and then switch the surveillance footage back to the real-time footage of the real exhibition hall at midnight to cover up the criminal behavior. Midosi expressed doubts about this and believed that building a fake exhibition hall would require a lot of money and time, while Ouyang responded by saying that it only needed to imitate the entrance and interior of the exhibition hall, and the value of the meteorite far exceeded the construction cost. Captain Wang provided the time and situation of the appearance of the "smiling face" sticky note in the surveillance video, pointing out that the surveillance did not capture the suspect. The conversation between Midosi and Ouyang suggests that Midosi may be close to the truth, but further verification is needed.

In the article, Midosi proposed four possible explanations to illustrate how thieves could stick sticky notes behind glass doors without entering the exhibition hall. Firstly, he considered using Bernoulli's theorem to stick sticky notes to glass through airflow, but this assumption was ruled out due to issues with wind speed and sticker area. Secondly, he proposed the possibility of using electrostatic stickers, but this hypothesis was also rejected because no electrostatic stickers or emitting devices were found on site. The third assumption is that the shadow of the sticky note forms a virtual image inside the glass door, but this assumption is not valid due to the instability of the position and virtual image of the physical sticky note. Finally, Midosi proposed the method of using wireless remote control for cars, which can be operated through glass doors and is considered the most reasonable explanation. Mavika expressed excitement about this and believed that the answer had been revealed.
