As long as the agreed-upon matters of both parties were written in the book, if either party breached the contract, they would die mysteriously.

Although it has many restrictions, such as the person writing the guarantee has to have a higher cultivation level than the contracting parties.

Shu Guan curiously opened the jade order golden book and picked up the colorful brush, drawing on the golden paper.

Shu Guan was taken aback.
"The old man once heard that this magical treasure has a special way of use, and only those who know the method can write on the jade order golden book, but the way to use it is only known by Laodao Bazi."
