This is a kingdom that has been shrouded in ice and snow for many years. It appeared in the depths of a distant fairy tale, and then slowly faded out of people's sight. People here use different levels of crystals to tear apart their souls and transform into various forms of weapons to fight. And at the last moment of the battle, no matter whether you win or lose, the fragments of your soul will turn into clouds and dissipate. Many people did not die on the battlefield, but passed away when their souls were exhausted. They could not go to heaven or earth. In the end, they could only turn into nothingness.
