From Gu Chen's memories, he knew each of the five mortal stages had nine layers. So, he continued and clicked on the plus symbol again.
[Do you want to use 200 Lust Points to increase your cultivation to Skin Refinement, Second Layer? (Yes)/(No)]
'Hm? The cost doubles?' he raised his brows and glanced at his total lust points. If this was the case, he wouldn't be able to attain even the Eighth Layer, Skin Tempering.
Fortunately, it wasn't doubling but increasing according to the fibonacci sequence.
An hour later, his cultivation had risen to the Ninth Layer of Skin Refinement Realm and 14,200 Lust Points had been used up.
"Nice." He smiled in satisfaction and clenched his fist. He couldn't tell just exactly how much, but he was a lot stronger than he was an hour earlier.
He looked at the cultivation section and saw the plus symbol was still there, meaning he could still increase his cultivation.
So, he didn't hesitate to click on it.
