"Didn't I tell you? Unless there's something important, don't disturb me."
Zhang Yan was interrupted by the sound of the door opening. Just as he was about to reprimand someone, he saw Xu Ping standing at the door with a blank expression.
"Fellow Dao... Elder Xu!" Zhang Yan quickly stood straight, shocked, causing the smoky object he held to drop to the floor with a crisp sound.
Du Xinghuai heard this and immediately became alert, sitting up straight with a sheepish smile on his face, "Elder Xu!"
"Hmm."
Xu Ping nodded, his face expressionless.
"I... I suddenly remembered I have some business to attend to, so I'll be leaving now." Du Xinghuai found a flimsy excuse and dashed out, leaving Zhang Yan alone in the small room.
The young cultivator understood the gravity of the situation, seeing the shopkeeper and Alchemist Du show such respect to this elder, quickly made his exit.
