The End of the Natural Disaster! I'm a Martial Arts Instructor in the Last Days

[The end of the world + natural disaster + space + spiritual spring + strong female] When the gold medal coach was accidentally reborn in space. Stocking up on supplies, of course! As long as you can't stockpile it to death! Just hoard it to death! I originally thought she had taken the script of extreme survival in the apocalypse, but why didn't any of her new neighbors panic? Let's just say, do you know that the end of the world is coming? Class starts? Collect supplies? Is this some secret organization?
