Jiang Wu obtained the super exchange system before the end of the world. While people were still fighting for food, he had already built a base. While people were still studying zombie crystal cores, he already had an army collecting zombie crystal cores for him for him to upgrade. When people first used the crystal core, they found that he had already established a country. This novel and its characters are purely fictitious.
