"Elder Liu."
Chen Yun called out softly and looked at the basement that was emitting a black light. There was a faint light spreading inside.
"Phew!!"
Liu Yin let out a long breath and said, "This place has something to do with me. During the war, when the bandits came, everyone here had already been killed by the bandits. Only I know about this underground secret room."
"Ugh!"
Chen Yun frowned slightly. He felt that Liu Yin's casual words were very simple, but Chen Yun felt that this matter was not simple.
However, Liu Yin did not want to say anything, and Chen Yun did not ask.
"Are there air holes in the room?"
Chen Yun asked.
Liu Yin nodded and said, "There are many air holes inside, and there's often airflow. Even if the door of the secret chamber doesn't open for decades, air will flow smoothly. Don't worry!!"
The two of them walked forward.
