Anybody know this book name? In the first few chapters the mc wanted to sleep but he wakes up in his room or in his room in a mirror dimension /world where everything is rotten, corroded, creepy, there are no life or sounds of people. (he lives in an apartment in a city) After he looked out of his his window the surrounding building are rotten too and most thing are hidden in fog. After he leaves his room to search for food he meets with another human but before they got to exchange few lines the mc and the guy hear some sound. Guy got killed by an electric giantslug, after that mc fight and kill the slug with a knife /blade he got in the mirror world and ate the slugs core and gain a electric skill which gradually improves his body, and after this he got transported back to his room with his wounds and tattered clothes. He has a status screen /system. I think it was a Chinese novel translated on webnovel but I can't find it. Please share the novels name if you have it, thanks.
