Alien Sky City

A city floating in the sky, called Sky City. There are all kinds of creatures living in the Sky City. Monsters, undead, beasts, dragons, and powerful individual creatures. This has also led to the city in the sky being in chaos and war. Until the Celestial Clan and the Human Clan tried their best to divide the Sky City into 10 floors at the cost of the Celestial Clan exhausting their divine power and falling asleep, and the human race's strong men falling one after another. And stratify different races one by one according to different strengths. And leave the final artifact at the bottom to seal the strongest demon. Peace was restored to the world, but the good times did not last long. At some point the seal became loose. The strong men of the God Clan have just recovered, while the strong men of the human race have all fallen. The world is once again in crisis.
