Lin Mo transmigrates to the Tang dynasty and unexpectedly gains the ability to possess others, only to become a dying branch relative of the Lin family.
He possesses the sickly legitimate heir and uses modern knowledge to save the family’s successor;
he possesses an illiterate maid and offers a life-saving prescription during a plague in Chang'an;
he possesses an elderly steward, buys up an abandoned mine no one in Chang'an wants, and forges a peerless weapon that stuns the world.
During the An Lushan Rebellion, he possesses one of An Lushan’s guards to overhear secrets and move the family’s assets in advance;
when the Tibetans besiege the city, he possesses a low-ranking soldier defending the walls, sets off gunpowder, and blasts back an army of a hundred thousand.
By the time the Lin family has risen to the head of the Five Great Clans and Seven Noble Houses, Lin Mo has possessed 379 members of the clan.
A thousand years later, archaeologists discover a secret code hidden in the Lin family genealogy. Behind every generation’s decision-maker is the same pair of eyes.
