After the Fire Lotus Sword entered Ye Tianfan's body, Ye Tianfan was clearly able to feel his body becoming somewhat overheated.
Perhaps it was because the Fire Lotus Sword had already started digesting the Blood Fire Divine Stone inside him, causing Ye Tianfan to feel an overwhelming surge of blood qi.
The reason it is called the Blood Fire Divine Stone is that it is a type of stone with an extremely high fire attribute. However, after being irrigated by some high-level Demon Beasts, especially those that are fire-attributed, and repeatedly irrigated until the blood qi fully permeates the stone, it truly becomes the Blood Fire Divine Stone!
