In 2XXX AD, Tang Han, a desperate and poor detective, signed up for a time travel experiment in order to obtain a high bounty. His memory was erased and he became a "robot-like". His mission was to travel through the Northern Song Dynasty and uncover the mystery of "The Sound of Axes and Shadows of Candles".
But when he completed the time travel, he discovered that he not only retained his memory, but also shared a body with two souls - Song Taizu Zhao Kuangyin and the red agent "Kunlun" of the Republic of China; and the time and space he arrived at was not the ninth year of Kaibao in the Northern Song Dynasty, but the fourth year of Wanli in the Ming Dynasty.
Thus, Tang Han, the time traveler with the most powerful configuration in history, began his struggle in the last hundred years of the Ming Dynasty.
