Gu Tao glanced at the drink in his hand, "Because she's a demon... oh, she happens to be my girlfriend's friend."
"Hmm," Mr. Zheng nodded, didn't say much, then downed Ai's drink in one gulp and comfortably opened a bottle of beer, "That sobered me up. Another round?"
"Hehe!" Gu Tao stood up, biting open a beer bottle with his teeth, "Old timer, bring it on."
In fact, that Ai was of demon origins was no secret here. Gu Tao hadn't kept it from anyone except for the principle, who hadn't been around long enough to meet Ai. Almost everyone else basically knew about Ai's identity, but this wasn't surprising. Apart from Mr. Zheng, there wasn't a single normal person around.
After all, Mr. Zheng himself wasn't normal, living in the mountains for a lifetime meant he had his own stories to tell.
