Starting from the office buildings we kept passing through

Suddenly, the office building in the city center found itself transported to a jungle. Along with it came the cattle and horses that worked within the building. To survive, they had to face ferocious beasts and even more dangerous supernatural creatures. Killing these creatures also offered a chance to obtain mysterious cards. For food, water, and cards, people began fighting wild beasts and scheming against their own kind, all for the sake of survival. Just as they adapted to life in the jungle and gradually rediscovered their pride as apex predators, they were transported again. This time, they would face an even more dangerous environment, a more complex situation, and even more powerful companions. Could they survive to the end? And who was the mastermind behind all this? A god? A demon? Aliens?
