In the hierarchical Ark City, Lu Yuan, a garbage collector in the seventh district at the bottom, only relies on his ability to freeze time in critical moments. On this day, he rescued the boy Xiaoguang from the mouth of the aberrant beast, but triggered the ancient law - every time he saves someone, he owes a certain cause and effect. The blue light flashing in Xiaoguang's eyes means that the existence of Cthulhu in the deep sea has marked him. The next day, the upper levels recruited him in the name of a 'purification experiment', but in reality they were using the lower levels as consumables to absorb source energy. Lu Yuan paused time in the laboratory and saw the distorted experimental subjects tied to the instruments - they were all people he had saved! It turns out that the people he saves will be targeted by the higher-ups and become experimental subjects. Every time he saves someone, the accumulation of cause and effect will attract further attention from the ocean existence. Lu Yuan decided not to be passive anymore. He used the pause in time to steal the source energy cultivation method in the laboratory, rescued the survivors, and escaped back to the seventh area. He started to build infrastructure, using his ability to pause time to open up territory in the garbage mountain and take in the lower classes abandoned by the upper classes. But every time he saves someone, the chain of cause and effect becomes heavier, and the whisper of the abyss echoes in his mind. When the upper-level purification troops and the distorted waves of the ocean rushed into his territory at the same time, Lu Yuan stood on the newly built city wall, looked at the people he had saved behind him, and murmured: 'No matter how heavy the cause and effect is, I will suspend the despair of this wasteland. '
