Multiple Apocalypses: My Shelter Can Be Infinitely Upgraded

[Doomsday + rebirth + farming + developing forces + fighting for resources + system + natural disasters + monsters + abilities] The world has entered an era of doomsday. Heavy rains, extreme cold, zombies, insect plagues and other doomsdays are coming one after another, and the vast majority of humans on the planet have lost their lives! Reborn and returned to the day before the doomsday began, Su Wen awakened the shelter system and his home became a doomsday shelter! What did you say? ! Is the shelter too small? ! Upgrade your shelter to enjoy more space! What should I do if there is not enough food? Upgrade your shelter to get more food! The shelter is under attack? Upgrade your shelter to unlock the defense system! What? The enemy wants to carry out a beheading operation? Upgrading the shelter can improve the host's own strength! …… There's nothing that upgrading your shelter can't solve! If so, then the shelter level is not high enough! So the question is, how to upgrade the shelter? Recruit more members! The greater the number of shelter members, the higher the value and the faster the upgrade! Get specific resources! The more specific resources you obtain, the higher their value and the faster you upgrade! …… Su Wen is ashamed, doesn't this mean—— Others are struggling to survive in the increasingly terrifying apocalypse, but he is playing a leisurely farming game? ! (Note: The protagonist of this book is not a good guy in the traditional sense. Well... Maybe the modifier in front of good guy can be removed)
