Ji Zhuo personally pressed the reset button on civilization, just to end the cycle of human self-destruction. Seven days later, the world will fall into time collapse, and only he and Lu Xiao can reverse the outcome - but Lu Xiao is the cold-blooded commander who personally sent him into the experimental cabin. In the memory fragments, they were once comrades-in-arms side by side, but now they regard each other as error codes that must be cleared. When the city froze in silence, and when the AI began to read their childhood diaries, Ji Zhuo realized that restarting was not redemption, but a revenge ritual that Lu Xiao had buried for ten years. What he wants to kill is not civilization, but himself who once believed in love.
