A nobody is reborn in another world, only to find himself married into a family as a live-in son-in-law, dismissed by everyone as useless. After an accident, Chen Jun discovers that he can control his shadow with his mind. From then on, he can master alchemy, sword forging, martial arts, beast taming... Anything he thinks of comes naturally, without a teacher. Sorry, even the alchemy master takes too long to bring me tea, and the sword-forging master is nothing special. Who's the Martial God? Is he really that strong? The shadows of everything in this world are my power. A little tiptoe, and even the Myriad Worlds will tremble.
