Naruto: Unlocking Kaido Template - Chapter 3

For twenty years since his soul had transmigrated, Bailuo thought this was an ordinary world, until one day, a black leather book appeared in his mind.“Is there magic in this world?”Facing Bailuo’s question, his uncle remained unwavering as he said, “No.”“But there are miracles.”“What are miracles?”“A sword that can release flames, a pot that can pour out gold, a beautiful girl grown from a fruit.”The uncle said, “Controlling the mist, bringing the storm, commanding the thunder.”“Magic!”Bailuo raised his hand and pointed, “This is definitely magic!”“No.”His uncle said, “These are truly miracles.”Years later, when Bailuo looked upon the nation he had built with his own hands, that magnificent and majestic sight, he agreed with what his uncle had said all those years ago, “This is a miracle…”

Seol Woon-hwi, the Blood Heaven’s Righteous Blade, rose to power, becoming second to none under the heavens, reigning just beneath the sky itself.Yet, at the height of absolute power, he finds himself returned to his past—back to his days as the scorned illegitimate child of the Everlasting Snow Palace.

He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
