Cheating
A week has passed since Su Yang's first lecture, and the Junior Disciples returned for the second lecture without a single one of them missing.
"I want everyone to have a different partner this time," said Su Yang.
The Junior Disciples immediately began looking for a new partner.
Sometime later, once everyone has a partner, Su Yang spoke, "Good. Now repeat what we did last week and prove to me that you have been studying properly."
One minute later, when Su Yang saw that everybody there had their fingers pointed to a specific spot on their partner's back, he nodded in approval.
"Although half of you took longer than half a minute to find your partner's vital spot, I am glad to see this big of an improvement from all of you. With that being said, none of you managed to awaken the vital spot, so you still have much to learn."
A few moments later, the roles switched, and those who poked are now being poked by their partner.
