The secret manual was prepared, and his prank was also ready to go.
As for whether there was really a fool who would really cut himself after reading the first page, Chu Xuan did not care.
Of course, if there really was a fool who cut himself, in order to encourage the other party to work hard, Chu Xuan would also leave behind a shred of hope, stating that after they had mastered this cultivation technique, it would allow them to regrow their third leg.
As such, even if a fool were to cut himself, in order to regrow his third leg, he would naturally cultivate diligently; working even harder than anyone else.
As for other precious materials that could be used to regenerate limbs and organs, the other party would definitely look for them.
Such precious materials were extremely rare, and it was not easy to find them.
One would also need to be extremely powerful to obtain them.
