A weak voice reverberated in the core region, and the evolution cube in Lu Yuan's body suddenly shook violently.
Lu Yuan looked at the door in the direction of the sound in shock. He could not see anything through the window.
"Big brother and big sister outside, can you let Yue Yue out? It's so dark here, I'm so scared ..."
Lu Yuan looked at Li Qinghe in surprise.
"Sister Qinghe, this is?"
Li Qinghe said sternly,
"Do you still remember what I told you just now? In the core zone, no matter what you hear, just pretend you didn't hear anything. Don't believe their words. Let's go in and take a look."
The two of them came to the room where they were talking. Through the window, Lu Yuan saw a little girl who looked to be only five or six years old. She was standing in front of him and knocking on the door with her little hand.
As if she felt his gaze, the little girl looked up at the window, her dark eyes looking pitiful.
