Four of the Ten Kings of the Ten Heavenly Cities had arrived.
As long as there were five king level existences, they could open the first palace of the Ten Kings of Hell.
The people who came were the Aotian King, the Qian Ning King, the Northern Spirit King, and the Kongmie King. They didn't expect a powerful figure to come at this time. This powerful figure could be said to be one of the top existences in the Qing-Yun Realm.
He was the ruler of the Sky Dragon City, the Sky Dragon King. The Sky Dragon City was the largest city among the ten cities, and it was also the headquarters of the strongest force, the Sky Dragon Sect. He was also a king-level figure among the countless forces in the Heaven Region.
Such an existence was simply a legend.
