In the four great chaos, there have always been some precious artifacts, like Tao stickers, which, although not the ultimate treasures of chaos, are, in some sense, no less valuable than them.
When the nine Tao stickers emerged back in the day, they caused a stir.
As long as it's related to achieving the Tao, there is nothing simple about it, and its value is never low.
And the book that Emperor Che mentioned earlier, is actually something that has always existed within the four great chaos, containing records of many Secret Techniques.
It was also snatched from a master of chaos from Tai Shi Chaos.
The material of the book, even those of master rank don't know its origin, and the Secret Techniques recorded within are unheard of by them.
The three great chaos studied this book for a long time, but gained nothing significant in the end.
Later, Qian Ren negotiated to obtain the book, and after the three great chaos set some conditions, they handed over the book.
