"Hey!" Xu Tian leaned against the wall to rest. He panted heavily." We didn't encounter the ghost wall on the fourth floor just now. Is it happening again on the seventh floor?"
"Since we're already here, why don't we take a look at what's on the seventh floor?" Ming Ze walked down the stairs calmly and opened the security door on the seventh floor.
"Cough, cough, cough!"
A cloud of dust immediately blew in their faces, and the three of them choked.
"What is this place? Why is there so much dust?" Xu Tian covered his mouth and nose with one hand and walked in while waving the dust with the other. The corridor was full of dust, and he almost couldn't see the direction clearly.
However, when he barely managed to see everything in front of him, he suddenly realized that he had not received any response even though a few seconds had passed. The surroundings were silent.
