The two laughed hysterically, seemingly dismissing Yang Yifeng's methods with contempt. Even Bi Chi cast a doubtful glance at Yang Yifeng, uncertain of the utility of the silver needles he had just inserted.
However, based on his understanding of Yang Yifeng, Yang Yifeng would never do anything pointless.
"Haha, I hope you can still laugh afterward!"
Yang Yifeng took out another silver needle and flashed it in front of one of the middle-aged men. His face bore a mysterious smile, "Those silver needles I just inserted were not placed randomly. Now the sensitivity of your sensations has increased by a full ten times! I think, you will have a memory etched into your bones after this!"
After saying that, Yang Yifeng pierced the silver needle into an acupoint under the armpit of the middle-aged man.
"Yang Yifeng, huh? Ha... Haha! Hahaha! It's so ticklish!"
