It's impossible for someone under the bar to suddenly disappear under normal circumstances.
The place where the bartender was standing was near the bar's railing. If Meng Xinian wanted to come out, he would have to pass by him and push open the half-height bar railing to get out.
But doing that, time wouldn't allow.
If the bartender pointed him out, claiming he was there before she went into the bar, but disappeared as soon as she entered, the suspicion would also fall on her.
Although these are guesses, they are also reasonable assumptions.
Knowing that such laboratories and research institutes exist, Chiang Xiao was very cautious not to let such suspicions be exposed.
Because you never know if among the people around, there's someone engaged in that kind of research. If such a person encounters you, they will immediately fixate on you.
That group is full of madmen.
