Tactical Survivors in the Apocalypse

In a parallel world with no superpowers or zombies, society collapses after three years of apocalypse. Zhang Yi's hunting team of twelve is betrayed by their 'helpful neighbor' Red Beard, and all are killed. He returns to seven days before the apocalypse with a 50-cubic-meter constant-temperature space. This time, he empties the town's supermarket, gun store, gas station, and pharmacy, and seeks revenge. When the snow falls again, Zhang Yi and his team are safe in their fortress while Red Beard can't even find the door.
