The townspeople have been taking refuge in the supermarket for over seven days now.
Although this kind of supermarket has an ample supply of food, everyone is showing signs of fatigue under the power outage and the shroud of the mist.
Add to that the fall from the 'false soldier' rescue, the precipitous drop from the peak of salvation to the abyss of death, as well as the psychological pressure of witnessing the horrifying octopus-like life form.
Many people with poor mental resilience have shown signs of mental illness such as hallucinations, insomnia, and agitation. The supermarket medicine supply is basically at a low.
Even a middle-aged woman was found hanged in the women's bathroom. She could not bear this pressure.
Being alone and barren, her husband had died in a car accident two years ago. In such an environment, she chose what she thought was a 'comfortable' way to end this nightmare.
