Shen Congru gave Xu Xiangbei, who had landed on the building top, an OK gesture, then piloted the helicopter slowly away.
The evening wind roared, making the black clothes on his body flutter intensely. Xu Xiangbei worried that the black mask would fall from his face, so he touched his face and felt the mask was still tied on.
Before entering the building, Xu Xiangbei opened a weak electrical shaft on the top floor, full of intertwining colorful wires controlling the building's surveillance video lines.
Xu Xiangbei called Liu Ningyan, and under her guidance, he cut a red wire: "I'm about to enter the building. Can you control the surveillance video remotely?"
Soon Liu Ningyan's voice came over the phone: "Okay, you can go down now. I've taken control of the building's surveillance video; no one will notice you."
Feeling reassured, Xu Xiangbei opened the iron door leading to the building, entered the high-rise, and arrived at the door of Lei Ziming's office on the top floor.
