"I really can't understand one thing, why would Niu Rang want to leave some other clues in my plantation and then hand the gun over to me? Isn't this going in a big roundabout way? Why not simply take the clues he had and give them to me so I could transfer them to you?" He Zhilan pondered over this question for an entire afternoon.
He Teng, Xing Ye, and Lan Li all guessed that Niu Rang must have gotten ahold of something very important. When he obtained this thing, he probably hadn't realized that his undercover identity had been noticed, so he must have been planning to deliver this thing by himself. Then, before he could make the delivery, he discovered that his identity had been exposed, and presumably, he no longer had the chance to pass the thing to you. That's why he left clues in the gun, using the delivery of a dress as a cover, and placed the gun inside the dress for you." This was the conclusion drawn by He Teng, Xing Ye, and Lan Li.
