Reverse Time and Space and Build a Trap-Like Steel City at the Beginning

[Doomsday + Rebirth + Supplies Stocking + Mobile Shelter + Farming Lord Management] The end of the world has come, and zombies have flooded the city streets, forming a new civilization. Human beings have no power to resist and are completely reduced to being raised as meat animals. They always live in the sheepfold planned by zombies, in a state of confusion and never see the light of day. Gu Cheng reversed time and space and was reborn. With the memory of his past life, he accumulated tens of thousands of tons of steel and was bound to build the strongest steel mobile fortress in mankind. When rows of zombies rushed up, trying to capture his residents for blood food, he happened to be short of crystal cores. Gu Cheng opened the gate of Steel City with a smile and even held up a banner, determined to bring an assembly-line life service experience to zombies. Excellent service, so far no zombie has not said good things about it. "When is Dawn City coming? I heard that housing prices have risen again. I hope that when we come here, housing prices won't be too high." - Looking forward from the zombie-occupied area "Once Shuguang City passed by me, I didn't get on the bus. Now I can only catch up with all my strength." - Brother, I haven't got on the bus yet. "That human city is simply too scary. None of the brothers who went there have ever come back, woo woo hoo~" - a speech from the zombie victim.
