Transmigration is the total rage of novels nowadays, and if the main character isn’t careful, they get swept up into the bandwagon, so this is a story from another continent. Magic? —— of course the main character won’t know how to use it, but what about knowing how to use electricity? Dou Qi? —— the main character still doesn’t know, but is inner power more strong? Beautiful women? —— of course the main character has them, or else there wouldn’t be anything worth reading in this novel. How many? —— that question’s quite good, if I told you everything, what would you read for? An honest warning to the female readers and your tastes, it is a harem novel, don’t read it if you’re not interested. A stern warning to male readers and your tastes, um, it’s like a breath of fresh air.
