Kenji’s life was hard. During the day, he worked in a bookstore. At night, he served ramen. He did it all to take care of his family. His mom was sick and needed medicine, and his little sister needed money for school. His best-paying gig was working for a mysterious author, illustrating the manga for a popular web novel. There was just one problem: he hated the story.He was in the middle of drawing the academy arc when his frustration peaked. The story’s villain, a rich kid named Azrael Ashveil, was weak. He made dumb mistakes and died unfairly. Kenji thought the character deserved better. After finishing a panel showing Hero's Victory, Kenji collapsed from exhaustion.He wakes up not in his small apartment but in a fancy bed with silk sheets. Looking in the mirror he sees the handsome, violet-eyed face of Azrael Ashveil. He has entered the story he hated and is now the doomed villain.Worse, he's arrived late to the party. The original Azrael has already made a mess of things. The story's golden-boy hero, Kaelen, already despises him. His beautiful wife, the half-elf heroine Elvara, is terrified of him. And all of his death flags-the events that lead to his execution are right around the corner.Azrael must use his knowledge of the future just to stay alive. Can a minor villain with no power of his own really change his fate, or will he just find a new, even more tragic ending than the one he was trying to escape?

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 to build something you need resources and energy. To receive resources you need strength. To gain strength you need knowledge. To gain knowledge you… need strength? or a background? Or maybe a fully armed army of high tech robots who aren’t afraid of death?

But is this legacy really for him to keep?
