Doomsday natural disasters are raging, with high temperatures and heavy rains hitting the country for several years. The system gave three skills. My sister took away "Repeat Action" and "Mark" first, and I silently picked up "Fix". When the water and electricity were cut off, I used my skills to vacuum-preserve food; when zombies attacked, I completely sealed the doors and windows to create a safe house. My sister was attacked by zombies for violating the rules and was seriously injured. But she blamed everything on me, marked my closet, and lured all the zombies to my house. I tried my best to protect her, but she frantically moved me into the zombie group; "Why can you live a good life and have to carry it together!" When I opened my eyes again, I returned to the day when I chose skills.
