Survival in the Apocalypse: Pick up Rags and Survive

Zhang Yong, who has been retired from the army for many years, has been working as a security guard in the past few years and living an ordinary life according to the rules of social animals. Who would have thought that one day when I was blowing the air conditioner in the security booth and got up to do the tasks assigned by the leader, I accidentally entered a world with the background of survival in the apocalypse. His safe house is in tatters, the zombies outside are blaring excited horns, and the system is still arranging survival tasks with malicious intentions. . . If you want to survive, you must upgrade the safe house. When the health bar of the safe house reaches zero, you will also be wiped out. Zhang Yong was stunned for only a second before he picked up the steel pipe and chose to fight head-on. Isn't it just about upgrading the house? Simple! Not only will he survive, he will live well! Each copy of the game can only be kept for 30 days. When it expires, it will be placed in a new copy by the system. Zhang Yong looked confused and started to fight zombies as soon as he opened his eyes. Is it easy for him? However, by killing zombies and brushing the protective shield, Zhang Yong thinks that this little life has become more and more beautiful as time passes by picking up garbage and transforming items. Are there people still chasing after me to buy my modified weapons?
