The Ancestral Master always responds to requests. Since she was asked where she bought the potato chips, she truthfully informed them.
That evening at dinner, four top students sneaked out and bought every flavor of the same brand of potato chips from a small supermarket, leaving the shop owner bewildered.
Owner: ...Do all top students love potato chips this much nowadays?
Liu Zhen watched these dummies in front of him suddenly become quick-witted, quickly responding to everything he said, feeling a bit sour inside. If only he could have eaten the potato chips sent by the Ancestral Master when he was studying medicine, how would he have ended up being scolded by his master for being a future mediocre doctor?
The advantage of having Liu Zhen here is that he can teach them, and she can just sit aside supervising.
"With the Ancestral Master's approval, I shall teach you the introductory content of the Thirteen Acupuncture Techniques of Lingdao."
