"The Gray Era"
The plane crashed into the blue-grey ice field of the Arctic. Only Li Jiazhong and Cai Zhengyang survived. Amidst serious injuries and severe cold, strange things happened one after another: inhuman flashes of light at night, whispers from the ice abyss, and the return of his "dead" best friend Zhu Jie - a "him" whose skin glowed with porcelain light and felt like black ice.
Following this strange afterimage, Li Jiazhong stepped into the icy abyss, only to find Zhu Jie's frozen severed hand and an icy idea calling itself "the system". In order to escape the "periodic cleansing", he was forced to jump into the blue light rift and fall into a black corridor that was as smooth as a mirror and swallowed sounds. At the end, twisted traces grow next to the doorway, and the afterimage of Zhu Jie's last pain is reflected in the pure black. A dark shadow that absorbs light is silently inviting him to enter...
When a best friend becomes the deepest nightmare, the only way out is to the inhuman core. They must solve the cruel puzzle of survival in this gray hell with will before the "digestion" of the ice sheet is completed.
