The old continent collapsed, and humans survived on floating islands 10,000 meters above sea level. The core resource is "Floating Crystal Stone (Cloud Crystal)". There is a lack of oxygen at high altitudes, there is the threat of "gasification disease", there are "dark energy storm tides" every day, and alien beasts run amok. Survival is extremely cruel.
The entire Ten Thousand Tracks Heaven Realm is the "Cloud Sea Pasture" raised by the ancient gods, used to harvest beliefs and emotions. The descendants are the "variables" in the compromise between the "main god system" and the ancient gods. Underneath the Abyss of Annihilation, there exists an "anti-gravity surface civilization" trying to pull the sky back to the ground.
[Soul extraction from all realms and concept smelting]. The core concept of the soul of an extraordinary beast or a dead creature can be stripped away and fused with the protagonist's vehicle (the Void Whale) to obtain its innate abilities.
