Shen Yi was only able to come back to reality once he heard the word 'medicine'. At the same time, he had a strange feeling inside. Chang Geng's eyes seemed to be glued to Gu Yun, detecting even his slightest movements.

Gu Yun wanted to deny it out of habit.

Chang Geng spoke first: "I still have not tried out the acupuncture method that Miss Chen showed me last time. This matter may not be finished yet. I am afraid there could be more developments, yifu, please let me try."

Gu Yun now remembered that Chang Geng already knew, so trying to hide any further was only useless. He left behind a sentence, "I will go rest in the back for a while" then silently followed him.

Chang Geng's bag carried a set of silver needles, some common medicines, broken pieces of silver, and a few books — Gu Yun soon discovered that this child might appear sharp and well-dressed, but in truth, he only had with him two sets of elegant articles of clothing to change into.

Gu Yun could not comprehend, when Chang Geng was a child, even taking him out to the market required every trick he had. In the end, for what reason must he insist on leaving the capital, living his days by wandering and tasting hardships?

It could be a fresh experience for a month or two, but would it still be fresh even after four years?

Chang Geng had performed acupuncture for many people before, but at this time, facing Gu Yun alone, he could not stop himself from tensing up irrationally. He hadn't felt this way even when he followed Miss Chen to learn acupuncture for the first time and performed it on himself. He unconsciously repeatedly washed his hands over and over, almost washing away his skin, until Gu Yun could not wait anymore, urging him: "Miss Chen has been teaching you this long, did she only teach you how to wash your hands?"

Chang Geng swallowed, his voice was tight, cautiously asking, "Yifu, can you lie on my lap?"

Gu Yun did not think there was anything wrong with it, after all, this was not a lady's legs, there was nothing to be afraid of. But he had really wanted to ask, 'can you actually do this?' — however he was afraid his words would increase the pressure on the half-hearted Doctor Chang Geng. Swallowing his question down in the end, he just thought generously: "What is there to fear, I'm not going to die anyway."

He had prepared to feel needles on his flesh, but Chang Geng was not at all as unskilled as his imagination. The very fine needles pinned into his acupuncture points basically had no sensation. After a while, the familiar headaches arrived again, there was no telling if it was a psychological effect, but Gu Yun truly did feel much better.
