Demon Slayer: Kimetsu No Yaiba: My Years as an Undercover Agent

I am Mu Linyin, a fan author who died suddenly after staying up late and transformed into a newly born evil spirit in "Demon Slayer: Kimetsu no Yaiba". There is no system, no golden fingers, just a body that wants to run away when it sees the sun and drools when it smells human flesh. The first thing I did when I woke up was having a living person in my mouth. While I was crazily chanting "Don't collapse the house" silently, I tied the unlucky guy named Murata into a rice dumpling with my backpack straps. From then on, the most ghost-like ghost in history began his journey of survival: he was so noisy by Zenitsu that he collapsed and knocked him unconscious with his backhand, and was dubbed the "lonely war ghost" by the Demon Slayer Corps in awe; he set things free on Kanahu and let her see her dead sister; he was treated as a tool ghost by Muzan, and he complained crazily every day under the suppression of his bloodline. Until I met that boy. Tanjiro put the knife on my neck, but he smelled my tears: "Are you crying?" In one word, defeat all the lines of defense I disguised as sand sculptures. It turns out that being seen feels so painful and so warm. When the decisive battle in Infinite City began, I finally made a choice—this time, I won't write about tragedy. I used the Vampire Technique [Memory Corridor] to pour the sins of countless millennia back into his mind, tearing open the cracks of victory for the Demon Slayer Team. The moment the sun shone in, I pushed Tanjiro out, and my smile disappeared in front of the light. "Tell Murata for me that the ghost that almost ate him can finally have a feast of human flesh in peace for the rest of his life." I am Mu Linyin, I was the stepmother author in my previous life, and I am Xiangyang's ghost in this life. These people I protect with my life, please live well for me for the rest of your life. .....
