An Artless Poisoning

Naturally, inside the pastry was an essential, first-rate poison that Fan Xian had meticulously prepared for the journey northward.

He presumed that his companion, owing to his identity, also felt it beneath his dignity to cheat. Seeing that he had seen through it, Fan Xian gave a pained smile. "I was confident that this drug powder had no unusual taste to it at all. How did you detect it, Master Xiao?"

Xiao En looked at him and slowly closed his eyes. "You are a student of Fei Jie. No matter how you may try to distinguish yourself, you cannot escape his shadow. I consumed Fei Jie’s poison in your prison for decades. He and Chen Pingping could not bring themselves to kill me. They could only use poisons to damage my body’s meridians. If you had eaten pastries from a vendor for over a decade, and then one day, that vendor had a new apprentice who made a pastry, although it might taste of scallion, I think you would still be able to taste that vendor's product."
