Why?

The Scroll itself was an ancient parchment made using a rare material used for scrolls in the previous Chaos Era: monster bones that were ground into white powder and then mixed with various other materials to create a thick paste. Its aura was magnificent, and Long Wei thought he heard a faint roar from it. But he chalked it all up to the few days of extensive training he subjected himself to.

Qian Jian slid the scroll to Young Lord Lu, who was pretty quick to grab it, as if one of the girls beside him would snatch it before it reached him. Not wasting a single second, the scroll unfurled in his hands, and his sharp eyes squinted.
