The pace of the story is slower and more relaxed! Try to restore the real extreme cold apocalyptic scene as much as possible. In order to gain more sense of immersion, the protagonist Lin Qi is a junior student with a bachelor's and master's degree in computer science. Together with the female mentor Su Momo and the female doctor Lu Chenyin, they will overcome the difficulties of the end of the world. While surviving, they can also strengthen themselves, integrating AI, brain-computer interface, and other cyberpunk elements, as well as the legendary 749 game and the ancient traditions of the four families. It won't become a hodgepodge, but has a complete and clear story line.
