National Survival: My Items Can Be Automatically Upgraded

The whole world has entered a mysterious game, and people are struggling to survive in a foggy world. "Brothers and sisters, please give me a piece of moldy bread to satisfy your hunger." Luo Xinghe is making a burger with ketchup on it. "There are poisonous snakes in the fog. What if I can't kill them with my wooden stick?" Luo Xinghe was holding a crossbow and arrowing a rabbit while grilling meat. "Wow, after killing the monster, you will get a bronze treasure chest with food, water, tools and even blueprints in it." There were dozens of platinum treasure chests piled in front of Luo Xinghe, and he was worried about choosing the location to build the base. Ding... Three years after entering the world, there will be a wave of natural disaster beasts. Players, please persevere and survive. Tides of ferocious beasts, mutated monsters, biohazards, and meteorites falling from the sky. The entire human race is struggling to survive. Luo Xinghe looked at the technological and immortal aspects on the drawings and was troubled. Should I build a cosmic fortress? Or is it the capital of cultivating immortals?
