"Is this the end?" Huang Donglai asked as they reached the entrance to the inner door, staring at the thick stone slab blocking their path.
"Yeah." Qin Feng said while casually lighting a torch on a shelf beside them, "Only Xiao Zhun has the key to this door. There's nothing I can do."
As he said this, Sun Yixie also approached the stone door.
Brother Sun squinted his eyes and quickly sized up the door from top to bottom, then pressed his hand against several areas in the middle of the stone door, pondering.
"Hmm..." Huang Donglai was frowning at that time, running over to a keyhole in the nearby wall, inspecting it closely, and then mused, "Do you think it's possible... we could pour some liquid substance into this keyhole and then quickly solidify it into a solid to use as a key?"
"Ha!" Sun Yixie burst out laughing, "Or maybe you can stuff a crap in there, then cast some 'Ice Magic' to freeze the crap solid and see if that works?"
