She was originally the young miss of the Marquis Estate, but became a peasant girl due to a mixed-up at birth.

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.

But is this legacy really for him to keep?
