The clothes the girl wore were very old, and her posture looked stiff despite being straight. She was completely silent.
If Lu Sheng didn't see her with his eyes, he wouldn't even notice a person stood there.
As he walked down the stairs, he suddenly noticed that the medal Shizi Xing gifted him was shining a faint gray light.
He walked to the end of the stairs and brushed shoulders with the girl. The girl's face couldn't be seen clearly, so Lu Sheng continued on his way to the next flight of stairs.
"Whoosh..."
Suddenly, a breeze blew by, and Lu Sheng blanked out for a second. Goosebumps rose on his neck as he turned abruptly. But, there was nothing else behind his back. The girl still stood in place with her back turned to him as she stared out the window.
