Zombie Siege, One of My Soldiers Is Missing

Lu Yuan traveled to the end of the world where zombies broke out. He was infected at the beginning and turned into a zombie 4 hours later. The "Civilization Fire System" is activated, but this system has ridiculous restrictions - you can only create one soldier every day, and one less soldier will be created; upgrading consumes all the energy, and you will be in debt just after the upgrade; soldiers are at risk of infection when fighting zombies, and if they don't fight hard, they will have no energy to survive. Fighting zombies = earning energy = staying alive = feeding more people. There is never enough energy to spend, there is never enough food to eat, and there is never enough zombies to fight. This is not a cool story about the system crushing zombies, but a story about an ordinary person leading a group of people to struggle to survive in the apocalypse, from "survive" to "let people live" to "take back their homeland". The system is the tool, and the talent is the fire.
