The Heaven-Shocking Secret Collection is broadly divided into four levels.
The First Layer, Second Layer, Third Layer, Fourth Layer.
The classification of ranks is hasty, not because people intentionally do so, but because the Heaven-Shocking Secret Collection has been passed down from ancient times, and those who possess it are not likely to easily reveal it, making it difficult to judge its true worth.
Moreover, though the Heaven-Shocking Secret Collection is a severed hand or foot, it also has its own name.
"According to the characteristics recorded in the Heaven-Shocking Secret Collection, my left foot actually belongs to an ancient ancestor named 'Emperor Dun'!"
The Heaven-Shocking Secret Scripture records a vast amount of information about the Heaven-Shocking Secret Collection, and the traits described are extremely similar to the reaction from Wang Xu's left foot.
