I'm Just Trying to Install Modules on My RV in the Apocalypse

In the parallel world, zombies are surging, strange shapes are everywhere, and dangerous places are everywhere. Cui Ping came through time and at the same time, obtained the modular RV system. [Attack Module·Colorful Laser Cannon]: The RV has an external ultra-long-range attack weapon. [Defense Module·Reflective Camouflage]: The RV is optically invisible and can withstand rebound damage. [Survival Module·Water and Electricity Integrated Machine]: The RV realizes the conversion of water and electricity. [Body Module·Damage Transfer]: The damage suffered by Cui Ping will be borne by the RV. As the RV module was installed step by step, Cui Ping was able to swim freely in the crisis-ridden apocalypse. He drove his RV all the way from the Baimo Canyon in the far north to the Origin Coast in the far south, passing through various secret places and observing the world in detail. He drove from the extreme east to the extreme west, opening up the trading hub among various gathering places in the last days. He was known as the mysterious traveling merchant and the moving Hexi Corridor. Then, he went from the surface to the underground, from the ground to space... "Is this an RV? Are you sure it's not a starship?"
