"Not every building climber has a society. Some people prefer to climb alone," Rem Horton said. "The best building climber should be the so-called Spider-Man."
"Spider-Man?"
"Let me show you a video."
Rem took out his phone and played a video.
"Is that CL Building?"
"Yes, it's filmed by one of our members. Twenty days ago, we planned to challenge CL Building, so we went to survey the place. To avoid unnecessary attention, we always went there at night, and then we discovered this..."
In the video, a black dot appeared. It seemed to be a person on the outer wall of the building.
"Do you have a clearer picture?"
"No, it's filmed with a phone."
Kate took the phone and watched the video carefully. "He has climbing equipment, right?"
"Yes, it's the very popular Spider-Man equipment in the profession. You can't climb CL Building without equipment, because the wall has no protrusions."
