Lost in his own thoughts as he slowly moved closer to the city together with the rest of the people waiting in line to enter the Dragon Tooth Mountain City, Xuan Hao noticed out of the corner of his eye that there was actually someone in the Core Formation Realm waiting in line along with him, something highly unusual considering that even Nascent Soul Realm cultivators were hard to see among the people waiting in line.
Even more so after considering that there wasn't really anything inside the Dragon Tooth Mountain City that would be in any way useful to someone only in the Core Formation Realm.
From what he had managed to learn about the city during his journey through the Crimson Dragon Empire and a little small talk between the cultivators waiting in line, the Dragon Tooth City had been deliberately set up by the Crimson Dragon Empire.
