Countdown to Doomsday: I Rely on Interoperability Between Two Realms to Build an Empire

Social animal Lin Zhou accidentally activated the "Dual World Interconnection System" and gained the ability to freely shuttle between the peaceful modern world and the zombie apocalypse. In a wasteland world where zombies are raging and order has collapsed, a pack of instant noodles can make a dying top scientist donate black technology blueprints, a bottle of pure water can be exchanged for a heavy pure gold magic weapon, and half a loaf of bread can buy a complete set of individual soldier exoskeleton equipment. In the modern main world with abundant products, cheap high-calorie food, industrial seamless steel pipes, drone swarms and automated anti-riot equipment are all available. While the survivors of the apocalypse were still fighting for a piece of moldy biscuit, Lin Zhou had already brought endless modern supplies to quell the tide of corpses, built high walls, accumulated food, and built the first indestructible city in the wasteland; While the business giants of the main world are still trying to suppress this cutting-edge company with capital means, Lin Zhou has already mastered the controllable nuclear fusion, superconducting batteries and genetic antibodies brought back from the apocalypse, and is in charge of the lifeline of global economy and technology! ​Use your own power to buy and sell across two worlds; rely on the torrent of steel to rewrite the new order of doomsday. "Zombie crisis? No, this is just the starting point for me to build an interdimensional science fiction empire!"
