Ye Beibei was unprepared for a while, and she married Young Master Gu who was sitting in a wheelchair.

I thought that from then on, I would have lived a career as a wealthy man, rich and free, but I never knew I was enslaved every day to become a nanny.

Ye Beibei beat the table: Liar, I want a divorce!

Young Master Gu pushed a cute baby to his front: You still want to get a divorce even when we already have a child? Wife, you wake up!

“…” Ye Beibei looked at a cute baby, who was exactly like her, with a confused expression.

Who can tell her when she gave birth! ?

- Description from MTL

Lanz Kuroda failed his Awakening Test in the most spectacular way possible, he didn’t just rank low, his ass got slapped with an FFF. He was locked out of the system entirely, and sent home like the rejected tutorial character that he is.But when a cracked relic crystal he bought from a sketchy street vendor activates, it boots up something the world shouldn’t even know exists, a hidden system that logs him into an old, forgotten alt account, one with no level cap, restrictions, and absolutely zero oversight.By day, Lanz is still the same guy that no one aspires to be.But at night? In the dungeons?He becomes Zero, an anonymous hunter operating outside the system, clearing high-tier raids solo, and slowly building a legend no one can trace.The world thinks he’s a joke.He’s about to become its biggest problem.

Lancelot Haier came from a dynasty of politicians who had ruled with tyranny and oppression. Despite those origins, he despised his family and was willing to help the citizens who had long suffered under their rule.However—before he even had the chance to change his country, the people revolted. His entire family was executed, and he was killed along with them. In his final moments, he wished for a second life—one where he could redeem himself and carry the sins of his bloodline.Unexpectedly, that wish was granted.He was reincarnated into another world as the crown prince of the Kingdom of Aragon. But in this world, everything felt backward.The country was ruled by an absolute monarch. Feudalism was the norm. Technology resembled that of the late 1700s.Fortunately, in his past life, he had earned degrees in both mechanical engineering and political science—knowledge he once hoped to use to reform his homeland. Now, it seemed he would use them here instead.He would use his modern knowledge to transform the lives of his people, industrialize his territory, gain the upper hand in technology, and form alliances with foreign nations—all while navigating the treacherous waters of internal affairs and politics.P.SWhile Reincarnated as the Crown Prince draws inspiration from historical settings, political systems, and technologies of the late 17th and early 18th centuries, this work is entirely fictional.All characters, governments, names, and events—although some may resemble real-world history—are products of the author’s imagination or are used in a fictionalized, altered form for narrative purposes.This novel is not a historical account. It should not be interpreted as a factual representation of any real monarch, nation, revolution, or political figure.Lancelot Haier, his backstory, and the alternate version of different kingdoms portrayed here are entirely original creations. The inclusion of familiar concepts like feudalism, industrialization, and political reform serves the plot and world-building, not historical documentation.Readers seeking accuracy in history are encouraged to consult verified academic sources. This story is a creative work meant for entertainment, character development, and speculative exploration of “what-if” scenarios rooted in alternate history.Thank you for reading, and I hope you will enjoy the journey.
