Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

Nine years ago, humankind almost perished the day monsters came out of the Cracks– aka dungeons– that appeared all over the world.When all hope seemed to be lost, a select few awakened as Hunters equipped with a System.Thanks to them, the civilization recovered faster than one would expect after the apocalypse.However, another conflict presented itself later: the more the Hunters used their powers, the quicker they lost their sanity.Fortunately, among the Awakened People, there is a group classified by the System as Guides– and only these Guides have the power to soothe the Hunters and bring them back to their senses.Sounds great, right?But what happens when a Civilian is in a relationship with a Hunter who has a high matching rate with their Guide?“Let’s break up, Wonhee.”Yep, this is what happens when your Hunter boyfriend has a 76% matching rate with his Guide.Wonhee was dumped by her long-time boyfriend because she’s just a Civilian…… or so she thought.
