Apocalypse: My RV Can Level Up Without Limit

[Post-apocalypse + Hoarding Supplies + Dark Story + No Saintly Heroine + Multiple Heroines] After the apocalypse began in his previous life, Jiang Feng used his ability, awakened on the very first day, and its overwhelming power to build a large survivor base. But his most trusted brother betrayed him alongside his own wife, and they beat him to death with their people. To his surprise, when Jiang Feng opened his eyes again, he had returned to half a month before the apocalypse. He had also awakened a motorhome upgrade System. In this life, everyone who wronged me will pay! But first, I need to find a way to make some money before the apocalypse arrives! The System is great, but it sure burns through money!

Meanwhile, Jiang Feng lounged in comfort inside his fully equipped motorhome, eating barbecue, drinking cola, enjoying the air conditioning, and being pampered by all kinds of beautiful women. Some actress: “Please, Jiang Feng! Just let me get on board, and I'll be your dog!” Jiang Feng: “I've got plenty of dogs. I don't need another.” Some tycoon: “Jiang Feng, just give me something to eat, and I'll pay you whatever you ask!” Jiang Feng: “Your money is just wastepaper now. You might as well save it to start a fire.” Some rich kid: “Jiang Feng, I'm strong and healthy. I can be your underling!” Jiang Feng: “Sounds good, but you'll only be useful as farm equipment...”
