"Master Gu, what is so interesting that's got you carried away?"
Tang Ziqing looked in the direction Gu Tinglan was staring, but all he saw was just a vague, slender figure.
Gu Tinglan kept his gaze away. "It's nothing. I must have seen it wrongly."
"I think you are exhausted. You have been traveling between Yunzhou and Lincheng so often recently. How is it? Is there any progress?" Tang Ziqing said with a smile.
Gu Tinglan shook his head. "It's as old as ancient history. It's not easy to find the truth."
Tang Ziqing noticed that Gu Tinglan was not in the mood to talk, so he toned down his smile and patted the man's shoulder. "Well, all you have is that tiny bit of clue, so that's what you have to work on. If it isn't in Lincheng, maybe it's somewhere else with the same name."
Gu Tinglan was in deep thought. "Maybe."
