When Xia Yidao, who was working the night shift at a convenience store, swatted the 999th mosquito to death, his blood seeped into his ancestral pendant, awakening his causal sequence ability. When gray fog enveloped the city and brain-eaters crawled out of the sewers, Xiong Yiyi, captain of the ninth team of the Night Watch, arrived with thunder. From "100% sure kill by swatting mosquitoes" to "cutting off the line of cause and effect", this young man who always wiped Tang Dao at three o'clock in the morning opened the first crack on the road to becoming a god in the foggy night. "My sword will not kill the nameless people," he said, lighting the mosquito coils, and the shadows of hundreds of thousands of gods and demons behind him were resurrecting from the ashes.
