Knock, knock…
Someone knocked on the door.
Chu Liuyue looked back to see Cen Yi standing at the doorway.
"Master, I've solved the puzzle you gave me."
Surprised, Chu Liuyue stood up and walked over to him. She thus didn't notice the pattern on Qiang Wanzhou's glabella. "That's fast."
Cen Yi flashed a small smile at her as he handed her a folded piece of paper. "It's not particularly difficult. In fact, I solved it some time ago. It's just that I didn't have the chance to give you the solution, which is why I'm only giving this to you now."
Chu Liuyue took the paper from him and unfolded it, surprise surfacing in her eyes as she quickly scanned through it. It was only a while later that she looked up and smiled helplessly at him. "You're the only one who will say that it's not difficult."
