Sima Yi can see ghosts through his left eye.
At the age of nine, he saw the ghosts of the Ten Regular Attendants enter the body of Emperor Xian of Han.
For the next forty years, Cao Cao's headaches, Zhuge Liang's Seven-Star Lamp, and Cao Pi's ascension to the throne were all part of a game to usurp the nation, played by eight old ghosts beneath the imperial throne.
On the eve of the Gaoping Tomb Incident, the eight ghosts planned to use the Sima family to complete their final ritual.
In this life, Sima Yi won't fight for the realm.
He opens the ancestral Manual of the Eight Gates for Subduing Souls. His sword points not at Cao Wei,
but at the ghostly hands that have haunted the Han for four hundred years, the ones who stole the nation.
(Deep beneath the palace, the bronze stone in Ma Chao's arms suddenly grows hot. In Xudu, a thread of blood seeps through the blindfold over Sima Yi's eyes. As the two look toward the faceless bronze statue at the same time, the legend of the Four Guardian Relics begins with a thunderous roar.)
