Doomsday Survival Manual

Unprepared for the end of the world, no plug-in to rub with bare hands. Assemble a new energy fishing rod and electrotherapy the zombies without making a sound. Make spot welding machines, strengthen houses and vehicles, and make weapons. Extended range car? Isn't this a multifunctional, mobile and silent generator! Civil air defense garage? After completing the transition from peacetime to wartime, it is the fortress of doom. Use scientific methodology to reorganize the rules of the end of the world! Why are there always some people who have no life and suffer from the protagonist's disease, blocking the way forward for mankind?
