Speaking of this, the captain took a few quick steps and arrived at the wall directly in front of the cave. With a flick of his sleeve, the wall immediately rumbled, forming an illusionary stone door.
Seeing that the stone door was intact, the captain heaved a sigh of relief inwardly. He lifted his hand to his mouth and licked it, smearing his saliva all over it. He didn't forget to explain to Xu Qing.
"To open this door, you need my saliva and palm. Without this, no one can open it."
With that, the captain pressed his hand against the door.
"Open!"
The door rumbled and shook a few times before it stopped moving.
Xu Qing blinked and looked at the captain with Ling'er.
Wu Jianwu and Ning Yan also looked over.
The captain was surprised. After he retracted his hand, he simply changed to his left hand. After licking it more thoroughly, he pressed down again.
The stone door shook even more intensely but it still didn't open.
