The Lantern Keeper of the Abyss

Lin Ye died in the third year of the apocalypse, betrayed by his teammate Zhang Feng, who split his back with an axe. When he opened his eyes again, there were exactly 72 hours left before the global cold wave and zombie outbreak. This time, he wouldn't play the saint, nor form a useless team of goody-two-shoes. He sold his house, mortgaged everything, and cashed out two million, renting the entire underground parking garage of his residential complex, stocking it to the brim with water, food, heaters, and firearms. When the countdown hit zero, the outside was filled with zombie howls and biting cold. Lin Ye sealed the blast door, gnawed on a hot canned meal, and watched the crowds fighting over supplies on the monitor: This time, no one's touching a single bite of my supplies. — Description from novelcodex.org
