In fact.
It was not only the Great Court Heavy Cavalry.
Even Lu Yuan was quite surprised when he saw the massive walls of Great Yu City, radiating Five-Colored Divine Light.
The Ancient Clans had deep foundations; besides their main cultivation path, they also had profound knowledge of Yin Yang Five Elements.
Ji Hao and others, in order to resist the Great Court Iron Cavalry, had evidently poured their all, integrating Five Elements Treasures into the city walls of Great Yu City.
The Five Elements circulate endlessly, giving rise to one another.
Even if the Tingyuan Sect personally intervened, it would be difficult to breach these walls in a short time.
"Great Yu City is the Great Wilderness Gate. Unless they can breach this city, advancing recklessly into the Great Wilderness will inevitably lead to being caught in a dangerous situation, surrounded, and exhausted to death."
Lu Yuan pondered.
