The author has no understanding of pacing or timelines, Within 4 days the super technological planet with 10+ trillion people has fallen into riots, dark ages, feudalism, been conquered by newly emerging superpower, supers have made entire systems of both commerce and politics including newspapers that cross dimensions and markets that sell ultra rare system items. That was 4 days in story. My home town council has spent 9 years deciding whether to build a new dock on the nearby lake...

This story is moderately entertaining, there is some discrete racism and the main character internalized some persecution complex. The biggest problem is the lack of care in the early story, he gains a super space has huge possibilities to enhance his ability to survive so he should make a very well reinforced shelter right? Nope after he repairs the old ww2 bunker he rent then he upgrades it's ability to hide then spends a month and a half doing nothing but posting pics of food. Not nothing to get materials or upgrade anything.
