One of them said in a trembling voice, "Are-are you human beings or ghosts?"
"Ghosts," Gu Ning joked because she thought that it was funny. However, the man relaxed instead. "You can speak, so you're human beings, but get out of here right now. There is a group of bats flying towards here!"
They weren't curious about why Gu Ning and Leng Shaoting were here, because there were many grave diggers. It wasn't uncommon that others found this ancient grave.
A group of bats? Hearing that, Gu Ning immediately used her Jade Eyes and saw a large group of black bats flying towards this tomb tunnel from an anteroom.
