The World Is Frozen: While Others Are Seeking Survival, I Am Cultivating Immortality

God's punishment fell, the world was frozen, and all humans were forcibly sent to an apocalyptic game called Under the Ice. An ice cave, an ice-eating beast, and an unquenchable bonfire are standard equipment for everyone. Food, materials and other resources can be obtained by exploring the secret realm. As one of them, Ning Xuan, who acquired the 'Mountain and Sea' system due to an unknown bug, was terminally ill and embarked on the path of cultivating immortality in this apocalyptic world where everyone's goal is to survive. "Why do I have so many resources? You can only explore one secret realm every day, but I can explore five!" "What? You already have too much food to eat? Sorry, I was already fasting when I broke through to the Golden Core Realm!" "You've already built a hut in the ice cave? That's a pity. I can only live in the three-bedroom and one-living room I just dug out." "Can you understand the happiness of cultivating immortals?" Ning Xuan said. However, as more and more secrets are explored, the truth of the extreme ice world is revealed bit by bit... This novel and its characters are purely fictitious.
