After failing the college entrance exams, Chen Mo transmigrated straight to another world and became Louise the Zero's familiar. Although he died right there on the very first day, he finally discovered that he had the ability to start over from zero! Return by death? If he could try again, there was nothing to fear. Even though he had no System, no magic, had to sleep on straw and do odd jobs, and was just a commoner whom the nobles could bully at will, he had a golden finger. Even if he kept dying over and over, he would still complete the other world's main quest: build a harem! A commoner familiar starting from zero, of course, had to work hard too.
