Xiao Mu rolled up the Door-God Painting and put it into the Earth Seal Space.
This true Door-God Painting's power was far beyond the Mortal Realm's Door-God Painting he had used before, and it might prove extremely useful at some critical moment.
"What a pity!"
Glancing back at the Destruction Spear that had been used as a key, stabbed into the crevice of the Stone Wall and eventually merging with it, Xiao Mu felt a tinge of regret.
But it was just a tinge.
The Destruction Spear wasn't suitable for his use, as in his hands, it couldn't unleash its true potential, and certainly couldn't compare to the Door-God Painting.
Squeak! Crack!
He pressed his hand against the Stone Door, and the sound of gears moving echoed as the door was easily pushed open.
Hiss!
A streak of white light emerged from within the Stone Door and shot towards Xiao Mu like a sword.
Whoosh, whoosh, whoosh!
