"Qianqian, the mark of the underworld emperor has another great use. It's the soul-summoning banner."
The first thing Fan Jian said was Royal Flush.
Not to mention Li Xingyuan and the others, even the eerie Ghost Empress of the Qingming Pass did not know.
However, what was a soul-summoning banner?
Li Xingyuan asked, "What's the soul-summoning banner you're talking about?"
Fan Jian said honestly, "Use the mark of the underworld emperor to form a kind of ghost-based power for the soul-summoning banner. From there, you can open the door to the evil ghost hell and release the ghost curse spells of thousands of evil ghosts."
As soon as these words were spoken, Li Xingyuan and the others frowned, looking very surprised.
Of course, Su Qianqian didn't know how to use it.
In the Netherworld Hell, there was still an eerie one with the mark of the underworld emperor.
