In a world where magic was abundant and supernatural creatures existed, Jin Valter lived as a fallen genius. Being the son of two A-Ranked Hunters, Jin had inherited his father’s keen eye for martial arts and his mother’s innate talent for magic. Alas, before Jin could reach his full potential, an Outer Demon attack left his soul crippled and his body weakened beyond repair.

Now, Jin lives out his days bound to the hospital bed with nothing but his brains to keep him company. Gone were the days when his peers hailed him as a genius as he struggled to even conjure a spell with his body falling apart.

However, it would all change when on the Night of the Blood Moon, a unique visitor paid him a visit…

Wang Guorui traveled to Taiwan in 1895, and obtained a super gold finger—the Red Police Base.

Since then, the whole world has been changed.

The Emperor of Japan: “He must be eliminated, otherwise our great Japan will never have peace!”

The Russian Tsar: “Please stop fighting. I will marry my daughter to you and cede Siberia as a dowry.”

British Prime Minister: “Why did I wake up and the navy of the British Empire is no longer the number one in the world?”

German Emperor: “Dear and brave German soldiers, please persevere, our Eastern allies are coming soon!”
