The LED screen lit up, displaying the scene that had just occurred on the second floor, including the conversation between Xia An'an and Xia Wanwan, along with the footage of Xia An'an letting go and falling from the building. Every detail was shown without any discrepancy.
When Xia An'an fell, Xia Wanwan was even about a meter away from her. The preceding dialogue between the two made the truth instantly clear. Even Xia An'an's implied admission of the things she had done to Xia Wanwan in their childhood was completely aired.
Xia Wanwan was truly shocked. Although she knew what Xi Muchen was going to do, seeing such clear and complete footage of the conversation and video left her both surprised and delighted. Since Xia An'an had chosen to take action there, she would not have expected there to be video surveillance; Wanwan hadn't noticed any cameras and was puzzled as to how Muchen had managed this.
