Yet, after reviewing the surveillance video, he couldn't figure out how "Yun Shen" left the room, or how he managed to take Wanwan away.
Because, these two individuals never appeared in the surveillance footage!
It was truly eerie!
Two living people simply vanished into thin air!
...
Returning to Madam Mu's room, Su Chaoyang meticulously inspected every corner and, finding no signs of a struggle, concluded that Wanwan was "taken" while she was sound asleep.
Sound asleep...
Could "Yun Shen" have secretly drugged Wanwan?
...
After surveying "Yun Shen's" room, Su Chaoyang finally found some trace of evidence.
There were fine scratches on the balcony railing, where something had been hooked. Relying on his extensive expertise, Su Chaoyang recognized them as marks made by a metal cable.
Looking down from the balcony, Su Chaoyang could basically figure out how "Yun Shen" had disappeared.
