In the Hot Apocalypse, You Are as Hot as a Dog, but I Am Living a Comfortable Life

[Apocalypse + Rebirth + Stocking up on supplies + Urban abilities + Relaxation] Hou Yi was reborn and returned to before the high temperature apocalypse. He had unlimited space and began to hoard supplies! Refusing to be a licking dog, kill the mastermind who killed him in his previous life with one arrow to avoid the recurrence of tragedy. Come to Chou Country and shop for zero dollars. Sakura Country, who is living a good life in childhood, naturally has to go to "forced consumption"... Conveniently, they burned down that ghost shrine... We have to take home the flower-planting artifacts from the British Museum... … When the end of the world comes, everyone else will be as hot as a dog, but he is living a comfortable life. Drunk and lying on the knees of a beautiful woman, he wakes up and holds the power of the world. May the mountains and rivers be safe, and may the country be safe forever.
