Survival in the Apocalypse: My Space Door Can Be Upgraded Infinitely

The red tide is coming, the world is out of power, mutated creatures are rampant, and the city is in ruins! While others were still fighting in the ruins for a drop of water or a piece of bread, Xu Ran was already in the collapsed hospital, pushing open a water source space door leading to the rooftop! Awakening the "Space Gate" and "Super Physique", as long as you leave a mark, you can reach any corner of the world with one click! Surrounded by mutant dogs? Open the door with your backhand and send it into the high-voltage power grid! Want to be morally kidnapped? Sorry, my space gate only transports supplies and does not support the Holy Mother! Start by grabbing the last sip of water in the city, establish an absolute safe zone, and build an invincible supply line! Xu Ran: "Can't beat you? It doesn't matter. I'll open the door and go behind you to empty the supplies first!" [Hardcore apocalyptic survival + space gate superpower + decisive killing + humorous contrast + single female protagonist]
