Doomsday Natural Disaster: I Stock up on Guns First and Then Food

[Apocalypse + Rebirth + Crazy Stocking + Infinite Space + Infinite Shuttle] The end of the world is coming and the fittest will survive. Reborn a week before the natural disaster, Zhou Ye awakened dual powers at the beginning. Others are still grabbing instant noodles and mineral water, but I have already prepared an arsenal and a space full of supplies! My girlfriend who harmed me and my brother who betrayed me in my previous life? In this life, I will take care of you one by one and send you all to hell! Typhoons, rain, hail, magnetic storms, extreme cold and heat... Natural disasters are coming one after another? It's okay, I transformed my home into a safe house with iron walls. The heating is on 24 hours a day, I cook hot pot, drink some wine, and even my Erha is fat and healthy. What? You want to take advantage of the chaos to break into my house and steal supplies? Sorry, I have my Gatling and bazooka ready, just in time to test my firepower!
