Survival Across Myriad Worlds: An Ordinary Guy Survives With a Pocket Dimension

In the second world, the first few days of the apocalypse are the prime time to stock up on supplies, but the heroine chose to take strangers to see zombies on the first night, rested on the second day, went to a convenience store to stock up on the most basic supplies on the third day, and wanted to stock up on generators on the fourth day , but I don't know where to go to stock up. The heroine wastes her golden time and does some very inefficient things. She obviously has the Internet, but she doesn't understand and doesn't know how to search online. She goes out to collect supplies, all by walking, and doesn't know how to use transportation tools. Anyway, I feel annoyed after reading it~

The first question: Isn't there an extraction ability in the first world end screen? Why didn't I extract it? I didn't talk about the superpower later. Why didn't I want the superpower? The second question in Chapter 6: Didn't your cell phone lose signal before you went down with the girls on the same floor to kill zombies and collect supplies? How come you can still send messages in the community group to discuss how you guys are killing zombies outside, but the heroine is the only one whose cell phone has no signal?
