Changlong Island Prison.
It consists of eighteen levels and is also known as the Eighteen Levels of Hell.
The entire hell starts from the prison entrance on Changlong Island, continuously digging downward, reaching the deepest parts of the endless North Sea.
At the same time...
Because it connects with the cold soil that has settled at the seabed for billions of years, the icy breath constantly seeps into the prison from the frozen soil.
Meaning the deeper the level of the prison, the harsher the environment.
The strength of the powerhouses imprisoned there also increases with depth.
Such as Black Demon Heavenly Venerable, Cold Moon Heavenly Venerable, and Sword Heavenly Venerable, these three are imprisoned on the eighteenth level.
Among these powerhouses, not only are there prisoners captured by the Sky Alliance, but also forces like Beiming Palace, Nine Dragons Valley, and Giant Whale Alliance have detained people here.
It's truly a mix of dragons and snakes.
