"Ming'er, do you know what's most important in cultivating immortality?"
"The four essentials are techniques, wealth, companions, and a place to practice. Techniques come first, so..."
"Wrong! What you need to cultivate immortality is love!"
"???"
"Ming'er, I have a copy of Unmoving as a Mountain here. Take it home and practice diligently. But remember, you must remain a virgin at all costs, or else..."
His master never finished explaining what would happen otherwise, and Jiang Ming had no idea. It wasn't until he met the Holy Maiden of the Hehuan Sect that he understood: the cultivation art he practiced could greatly boost the strength of anyone who dual-cultivated with him, but gave him no benefit at all. He was practically a walking immortal herb.
"Ming'er, it's dangerous up there. Hurry and come down."
"Brother Ming, we promise we'll only cultivate once a day."
"..."
"Put it in writing!!"
