In the Xuanzhao Dynasty, where women were the most respected, war swept across Kyushu, and men were like grass. Fan Han was originally an abandoned son of a small border tribe. Because his family sacrificed him to the enemy in order to cling to the powerful, he unexpectedly awakened the "divine deduction" golden finger - which can peek into the three-day future and reverse cause and effect. He did not follow the right path of loyalty and bravery, but used cunning strategies to disrupt the court situation. From the death row camp to the empress's confidant, he took advantage of the situation to plot, counter-kill his relatives, disintegrate the enemy's country, defeat the powerful with his wits, and defeat the good with his magic. Everyone in the world thought that he was the sharp blade in the hands of the Empress, but little did they know that he had already laid a plan to overturn the world. In this chaotic world of female heroes, only those who don't play by common sense can control their destiny.
