"It really is an Underground City!" Jia Yulan's eyes widened as she looked closely.
"But we haven't even begun to decode the seal of the Secret Realm, and yet it has appeared on its own. Could there be some kind of problem?" Yan Ruyu's face showed worry.
Clang!
Mo Ying drew the Divine Sword from her back with a serious expression.
"No matter if there has been an accident or not, we don't need to have the slightest fear. Let's go down and take a look."
With that, Mo Ying flew towards the great canyon.
Yan Ruyu and Jia Yulan followed closely behind.
This canyon stretched for tens of thousands of miles, was eight hundred miles wide, and several hundred miles deep, with an ancient city built in the center that extended nearly a thousand miles long.
The buildings in the city were very old and exhibited an ancient charm.
Mo Ying, Yan Ruyu, and Jia Yulan descended and appeared in front of the southern city gate of the ancient city.
"City of Barbarians?"
