Ding Ning had stayed at Mo Qingyan's shelter, seen Chen Xin's shelter, and was even taken back to the official shelter by her dad. During her days at the police station, she gained insight into various shelters around the city, allowing her to understand the living conditions in these shelters post-apocalypse and draw distinct comparisons.
In terms of comfort, Mo Qingyan's shelter undoubtedly ranks first.
Although the shelter was built before the disaster, its design wasn't intended for this catastrophe, the living facilities and conditions were well-equipped, and Mo Qingyan had taken years to operate it meticulously, making it naturally comfortable to live in.
However, Mo Qingyan initially built this underground shelter for short-term refuge, planning to rely on reserved supplies for about one to three years.
Thus, in terms of self-sufficiency, her shelter can be said to be almost non-existent.
As for abundant materials, it's still the official shelters.
