Everyone traveled through time and came to a different world full of dangers. There are various threats such as extreme weather, Warcraft, monsters, hunger and so on. I feel like a fish in water here because I can connect myself in 99 parallel worlds and exchange resources.
If you lack skills, look for yourself in the world of cultivation; if you lack technology, look for yourself in the world of technology;
But with basic supplies, anyone can help themselves;
Just asking, what else are you missing?
Very well written, cheers
