This is a light gray scroll, and while it's called a parchment scroll, that's not entirely accurate, as it's not made from sheepskin.

Su Mubai couldn't discern its material, but from the feel of it, it was undoubtedly precious.

This scroll came from Situ Ji.

After signing the contract with the Palace of the Divine Dragon, it was placed in Su Mubai's backpack along with a letter for Huai Jian.
