Yang Yan was suddenly faced with a decision.
He could hide and wait for the other attendants to bring the old man a pot of regular drink, but the old man would likely finish it quickly, and Pei Ye might still not make it back in time.
He knew from the moment he saw the menu that the other party had only reserved two pots of drink, they might leave once those were depleted.
Alternatively, he could find a way to serve the potion-laced drink in front of him - he wouldn't attack necessarily, but the upset stomach could buy some time.
But if he chose that route, the reaction of the other party after drinking from the pot was unpredictable, and he would have to adapt as the situation evolved.
Maybe the garden was too crowded today, or there were not enough attendants, as the old man looked around and found no one to serve him. The old man got up and began looking for the green-clothed attendants.
Anxiety gripped Yang Yan's heart, he hid behind a pillar and pretended to be busy.
