After walking for about a few hundred meters, Nie Yin stopped.

He walked along the stone wall on his right and touched a protruding stone before pressing it down.

The stone sank into the stone wall, followed by a rumbling sound from the other side.

Clearly, this was another passageway to another secret chamber.

Nie Yin walked along the passageway and went straight up the brightly lit stairs to a room that looked like a study.

"You're here." A gloomy voice sounded, and the person didn't seem to be surprised by Nie Yin's appearance.

Nie Yin didn't respond immediately. Instead, he took a few more steps towards the bright place before straightening his clothes and bowing to the person in front of him with his back facing him. "Greetings, queen!"

"Hmph!" The queen snorted, disdainful of Nie Yin's insincere display of respect.
