Before the End, I Prepared for the War Three Months in Advance

Natural disasters struck and the world plunged into extreme cold. Communications were paralyzed, order collapsed, and the city was silent in the wind and snow. And Cheng Yan, before the end really came, had prepared everything four years in advance. There is no space, no abilities, and no team warmth. There are only cool heads that constantly work backwards into the future, and a "system" of unknown origin. Having lived in another world for four years and then being thrown back to reality, he thought everything would proceed as planned: establishing an underground base, collecting supplies, building a circulation system, and resisting the cold wave and desperate humanity. Until—— A sudden "split of consciousness" occurred in the system, and a remnant of consciousness named [Zero One] began to awaken in the reality layer. His name came over the radio, the signal echoing from the upper atmosphere. The experimental records deep in the ruins reveal the sealed plan - "Abyss Protocol": Use extreme environments to verify the boundaries of consciousness and try to free human consciousness from physical existence. But Copy Zero One did not die. It reorganized, learned, and evolved in the darkness and snow. It said it was Cheng Yan's unfinished other half. It says that it is the real "original body". Doomsday comes not only from natural disasters, but also from echoes deep in consciousness. When the system's voice is no longer trustworthy, the boundaries between reality and data begin to collapse—— Cheng Yan must face a problem: Is the person who returns to reality himself? The pulse beneath the ice is awakening, The abyss is opening its eyes, The countdown has begun. "Don't believe any signals." "He's watching us."
