"No wonder!" Huang Yi suddenly realized. Although he had never had direct contact with the Sand Thief King, he had encountered Guifu Heilang (Ghost Axe Black Wolf) twice, who was also one of the three Great Generals under the Sand Thief King. He deeply understood how powerful Black Wolf was, and he estimated that Lord Black Serpent was likely a figure of similar stature.
However, he was not afraid. He had evolved once again, and his appearance and aura were different from before. Lord Black Serpent would not recognize him.
Huang Yi glanced at the attendant and said, "You're so smart, I trust you won't reveal my identity." His tone was calm, but the threat within was unmistakable.
"Dare not! Dare not! I will certainly keep tight-lipped!" The attendant, just a regular NPC with no significant strength, could have borrowed the prestige of the auction house before knowing Huang Yi's identity, but now he did not dare to even breathe heavily.
