The time when the Earth Emperor and other Human Sovereigns fell is too long ago; in Canglan Realm, many humans have only heard of their supreme treasures like the Ancestral Weapon, Human Emperor's Pen, Earth Emperor's Tome, and Heavenly Emperor Mirror.
But there are few who understand the specific uses and appearances of these supreme treasures.
Most people's impression of the Earth Emperor's Tome is that it's in the form of a book, also known as the Book of Life and Death, and it's said that writing someone's name and birthdate in it would cause them to drop dead.
A few who have some understanding know that this miraculous use can only be achieved when the Earth Emperor's Tome is matched with the Human Emperor's Pen.
In the case of just having the standalone Earth Emperor's Tome, it can actually activate the Underworld Residence constructed by the Earth Emperor.
But as for what the Underworld Residence truly looks like, even fewer know.
