Sect Leader Tang instinctively exchanged a glance with Xie and Chi, puzzled by why Young Master Nan was suddenly laughing like this.
In fact, they had just been worrying about whether Young Master Nan might get angry because they hadn't hidden the fact that Shi Chun had prepared two copies of the letter, making it clear they had only brought one while the other had been "stored" away by them.
However, Young Master Nan clearly didn't take their "precaution" seriously. The reason for his unbridled laughter lay both in finding Shi Chun's actions amusing and in truly admiring Shi Chun's ingenuity.
After understanding the reasoning behind the letter delivery, he couldn't help but be impressed, marveling at how perfectly Shi Chun had chosen this messenger. Truly, it was baffling to imagine how Shi Chun came up with the idea.
