"Boss Xu, is Boss Xu there?"
Outside the closed door, a somewhat familiar voice called out.
Xu Ran followed the sound and quickly spotted a familiar figure standing outside the door.
Having called out twice without a reply, the individual quickly stepped forward, about to knock on the door, but Xu Ran rushed forward to greet, "Elder Zhang, I'm here."
"Oh oh…" Zhang Heyear saw Xu Ran step forward to open the door and quickly pulled back his hand which had intended to knock, scratching his head in a nonchalant manner, "So you were here after all."
"Yes, I was occupied with something." Xu Ran smoothly tucked the small blackboard away into a corner, "Elder Zhang, is there something you need?"
Ziyun and Star, who were initially about to head downstairs to test their improved powers, glanced at each other and halted their steps, perking up their ears to listen in.
