When the Abacus Clicks, a Wrongful Case Awaits

Ancient mystery + detective work + satisfying twists

When the abacus clicks, a wrongful case is sure to follow.

Transmigrated into ancient times as a judicial officer, Shen Suanzhi has no golden finger, only a black sandalwood abacus.

Others solve cases with torture devices; he does it with mental arithmetic. The accounts don’t add up? A quick calculation. The timeline has inconsistencies? Another quick calculation.

For a locked-room murder, he calculates a flaw involving half a tael of silver.

For a string of disappearances, he works out the traffickers’ hideout.

The whole yamen calls him the “Death-by-Arithmetic Magistrate.” All he asks is not to work overtime.

Until the day he gets someone’s case wrong, and realizes that the human heart is the hardest account of all.
