The first idea that popped into Yang Jingshen's mind was whether someone spiked his drink. After all, how else could he explain the peculiar sensations he was experiencing at this very moment? But then, he quickly rejected this speculation.
Because, these symptoms were different from what he felt when he was drugged last time. True– his heart was beating fast like a drum roll was playing out there in his chest, but his body was feeling chilled instead of being overheated. Not to mention, he didn't feel any sluggishness in his body or any other form of similar handicaps.
Besides, once he collected his scattered mind and speculated further, he started to think more clearly. Like, for example, who'd drug him in a place like this, when there're still people around him? Let us forget about the slightly antagonistic Guo Ying and the few handfuls of people around him. But there was still his cousin here, no?
