Li Mingyang, an ordinary office worker, enters a desolate world called Extreme City after scanning a QR code. This world is devoid of rules and laws; it is eerie, mysterious, and filled with violence. Only by constantly killing randomly appearing enforcers can one advance and survive. Faced with this cold-blooded world, the kind-hearted Li Mingyang undergoes extreme tests of humanity, friendship, and love. As he and his companions search for an escape, the controller behind Extreme City gradually emerges. This film is adapted from the popular Chinese animation Blood Code (血色苍穹)
