The Frozen Throne Tower of Yongning

50 Years ago, an extreme cold wave swept across, devouring life in the dark night, and covering the earth with ice and snow! The eternal Twin Towers were renamed Yongning Towers upon opening and are the last habitat of mankind. It's a pity that this is not a paradise. The remaining human beings are divided into three, six or nine grades, and they continue their hope under the gift of the 'King'. Fifty years have passed, and some 'parasites' living underground are eager for a brief moment of sunshine to break out of the ground and be reborn, but they don't know that a greater disaster is about to come... (The story is purely fictional!)
