Upon seeing the small medicine packet, Beisitian paused, involuntarily looking up at him, and coincidentally met his glance.
As he opened the packet, it was evidently talisman powder inside!
Beisitian's pupils contracted. Why does he have talisman powder? Most importantly, this powder is fine and even, definitely not produced by this world's talisman making methods, but rather resembles the Spiritual Pointing Success Talisman!
The man took the packet and left joyfully, even though Associate Professor Zheng's medicine is quite expensive, it is truly effective.
After the man left, Zheng Qiwai looked at Beisitian with a faint smile and asked, "Why were you so surprised just now?"
Beisitian looked at him silently, unclear about the meaning behind his words.
"Do you recognize my medicine?" Zheng Qiwai asked again.
Beisitian continued to remain silent.
Seeing this, Zheng Qiwai sighed, "Do you have a secret you cannot share?"
