Global Survival: Starting by Killing a Mimic

[Survival in the mist + shelter + ruthless protagonist + stockpiling supplies + no saintly heroics + transcendent powers + domination + conquest] [Main character: Dixiu] When everyone is transported to a mist-shrouded world, Dixiu wakes up to find himself completely naked. How will he survive? With only a drafty thatched hut and an axe, how can he live through a level 17 blizzard? When he realizes he is standing at Death's feet, how can he turn the tables? There is no family, no love here. There is only deceit and betrayal, and people willing to give up everything just to survive. Endless snow and wind hinder plant growth. Icebergs and meteorites may crash down at any moment. Cruel magical beasts tear houses apart, while demons from secret realms destroy the world. How will he survive these dangers? How will he break through the darkness enveloping the world? Death is not what is frightening. What is frightening is a soul imprisoned. Wherever the thunder strikes, all is annihilated. You flee; I conquer. Only the most awe-inspiring thunder can shatter the heaviest darkness. The endless journey stretches on, with storms ever at my heels. Darkness blankets all things. I will be the final ray of light in the darkness, shattering it with thunder. (Completely open world, no restrictions or rules, vast world)
