Yang Xiao definitely followed the two to the Golden City Hotel and went up to the sixth floor together.
Su Qian'er left with the middle-aged fat man, and it would have been strange if Yang Xiao could actually feel at ease about it.
So as soon as Su Qian'er left with that middle-aged fat man, he followed them and then, while the middle-aged fat man was not paying attention, he took a seat in another private booth on the sixth floor.
The spot he chose had an excellent view, allowing him to closely monitor the middle-aged fat man and Su Qian'er without being noticed.
Just like when he followed them, with his abilities, as long as he didn't deliberately expose himself, the middle-aged fat man naturally wouldn't be able to detect him.
Therefore, when the middle-aged fat man thought he was safely drugging Su Qian'er, Yang Xiao had a clear view of everything.
At that moment, he almost lost control of his emotions and stood up in a rage.
