Upon hearing this, Feng Jiu smiled slightly: "Regardless of whether I can win or not, since it is a challenge, of course we must state the terms in advance, am I right? Also, I don't know about the Rules of Heaven and Earth, so if I just fight with you in confusion, that's not very fair is it?"
"With your strength, if I want to win, it will be too easy."
Ling Tianyu sneered. His sleeve moved and a book was thrown out: "Take it and read it! This book contains the information on the Rules of Heaven and Earth indicated on Peng Lai Immortal Island. If I want to win, I will make sure that you will admit defeat!"
