Ye Cheng is a mortal and the cast-off son of the Qingyang Ye Clan. With no spiritual roots, he is sent to work as a bookkeeper at a trading firm. By chance, he obtains a copy of The Classic of Mountains and Seas: Two Realms. Using his lifespan as fuel, it lets him connect to the Spirit Expanse Realm on the left and Earth in the Age of Declining Dharma on the right. He trades scrap iron for gold and copper coins for spirit pills. With a ledger and a single abacus bead, he quietly carves out a path to the heavens between immortal sects and demonic clans.
But a far greater game is hidden behind the ledger. His second uncle embezzles spirit stones to supply the demonic clans. His younger sister is confined in a separate residence. Twenty years ago, his grandfather was imprisoned north of Yanjun Sea because of a tortoise-shell marking. The Myriad Poisons Grotto needs sixty living sacrifices to open a passage between the two realms, and the tortoise-shell marking on the back of Ye Cheng’s hand is the very key the formation has been waiting twenty years for.
Others cultivate immortality with spiritual roots. He does it by keeping accounts. This is a thousand-year game in which a mortal uses his wits to topple the geniuses. He’s keeping track of every last debt.
