Extreme cold, scorching heat, eternal night, acid rain, strange beasts... The endless disasters in our memories are about to happen again. This time, Guo Yun, with tens of billions of assets and the advantage of foresight, vowed to make up for all regrets. He sold off all his assets, crazily hoarded massive supplies around the world, and built his top-floor duplex into an impregnable doomsday fortress! While the neighbors were still struggling for a bite to eat, Guo Yun was already eating hot pot with his confidante in the warm fortress. When the world order collapsed and heroes emerged, Guo Yun controlled his mobile fortress on land, sea and air to establish his own new order in the wasteland!
