"Doctor Zhao, I'm not sick, I just want to buy some Divine Oil, do you happen to have any?"
Feng Laonian rubbed his hands together and grinned as he spoke.
"Divine Oil?"
Zhao Tienan raised his eyebrows upon hearing this, then started to size up Feng Laonian.
Now, Feng Laonian was nearly thirty, at most about 1.60 meters tall, skinny like a fishbone, plain-looking, and had a hunched back.
His face was sallow and emaciated, and his complexion was terribly poor.
He always bore dark circles, looking like an old man in his sixties, critically ill.
With his appearance, he actually wants to use the Divine Oil; what a big addiction he must have.
"Yes, the kind that keeps you going strong, without getting tired even seven times a night. I want to buy some to take home and use."
Feng Laonian coughed twice, then spoke slowly.
