Doomsday Empire-Zombie Tide

The Last Empire is a science fiction novel that tells the story of a huge empire established in a post-apocalyptic world.
In the doomsday world with scarce resources, I not only have to face the terrifying attacks of various types of zombies to save my life, but also have to work hard to get food and supplies in the real world. I should have been enjoying the super wealth brought by the time travel, but in the end I lived a hard-working life like a stowaway.
In the doomsday world, academicians, doctors, and experts in various industries do not want money. You only need to give them bread and milk. Technical workers can be hired by providing a pile of potatoes. And they are absolutely loyal. So, all those who are still running around in the doomsday world, as long as you want, except for money, I can meet any of your needs, hehehe...
Come on, come to my empire to help me fight zombies. I don’t lack anything now, but I lack healthy humans. Men, women, young and old don’t mind. Bullets and explosives can be used as much as you want, and planes and tanks can be driven as much as you want, as long as you can drive. Target: zombie tide, attack! ! ! !
