The man only sold medicine. He didn't do consultations.
The disciples from the Wuji Sword Sect felt that the man was swindling them.
Su Yiqiu asked the man, "How much is your medicine?"
"It cannot be bought by money," the man said.
"What do we need to use to buy it then? Spirit stones? We have some on us. How much do you need?" The currency for normal people was different from the currency of cultivators.
The man shook his head. "I don't need spirit stones, either."
The disciple that got poisoned was on the brink of death. Everyone got impatient. "What do you want?"
"Life."
The man's gentle voice sounded as though it was tainted with ice. Everyone shivered uncontrollably.
Life?
"One medicine, ten years of your life."
Shua—
The disciples from Wuji Sword Sect took out their swords and pointed them at the man. "Who on earth are you!"
"A physician."
