After Wang Yu got the key from Vainglory, the first person he had to find was Hermit.
Although this old man had a horrible character, he was relatively knowledgeable as a Hero job mentor in the background story.
Entering the small alley, Wang Yu held on to the key and straightforwardly asked, "Sir, do you know what this is?"
Old Man Hermit did not reply him. He picked up a brick from the side and questioned Wang Yu, "Do you know what this is?
"No…" Wang Yu shaked his head and said, "But it looks like a rock."
Old Man Hermit nodded and said, "Then I can only tell you that that thing looks metallic…"
"F*ck!" Wang Yu broke down. This old man had learned how to play with others' minds. He could have just said he did not know instead of playing such pranks.
Seeing how Wang Yu was upset, Hermit became more daring. He started nagging, "I am not some encyclopedia. Can you not ask me about every small thing? I am a busy man!"
