"Ten years outside, but only a day in here?"
Hearing Lu Changsheng's words, Ye Qiubai couldn't help but be stunned.
This is way more awesome than the Portrait Of Emptiness by God knows how many times! You see, even that exaggerated time Ancestral Artifact of the Portrait Of Emptiness can only achieve one year outside while one day passes inside!
"All right, I'll leave a part of my spirit here to guide you from time to time," Lu Changsheng scratched his head and said. "But I can only offer you some ideas. I definitely won't know the specifics of how it should be done."
Seriously, Lu Changsheng hasn't done much cultivation himself, how could he possibly know the exact effects?
Anyway, there's definitely no harm in doing this. According to the protagonists in the novels of the past life, aren't they always resolving issues with their constitution or some special cultivation techniques when in doubt?
