"Why are you leaving? There are still quite a few nice treasures in there." Wang Cai looked back longingly every three steps, hoping the old man would call them back and give them the treasures for free.
"Welcome to come again." The old man bid them farewell.
"These things should be very precious, and I have a feeling that when we get to the twentieth floor, we might meet an old man like this." Mu Can said thoughtfully while feeling the Divine Crystal in his hand.
"I get it now, do you know what this is?" Mu Can asked Wang Cai, holding up the Divine Crystal.
"What is this? It's neither a Spirit Crystal nor a Demon Crystal." Wang Cai replied irritably, still resentful that Mu Can had pulled him away.
"This thing, it could very well be energy purified from the body of an extraterrestrial evil demon." Mu Can shared his speculation.
"What?" Wang Cai nearly dropped the Divine Crystal in his paw.
