Kurokawa Risa is an ordinary office worker, who has practiced lots of cooking while living alone. One day, she wakes up in another world, with a concerned little spirit hovering over her! She has apparently been transported to a magical, spirit-filled realm by the will of the goddess, and there is no known way for her to go back. She is taken in by a wealthy couple, and they and her new spirit helper treat her with nothing but kindness. There is one problem, however–the food in this magical world is gross!

Outer yard disciple of the Tiansang Spirit Palace, Xu Xiaoshou, had average talent. However, after coming out of his death seclusion, he realized that everything had changed. He had received a Passive System with many strange, miraculous passive skills: He would become stronger with every breath. He would become stronger when he got attacked. He would become stronger when he got mocked… Xu Xiaoshou was forced to shout, “Oh God, I don’t want to be like this either. Everything I did was because I was being forced to! I am so passive!”

“I got transmigrated into a novel because of a bad review?”

Eren found his life turned upside down when he woke up as the character that he had just finished cursing in a negative review!
