The Border Wall's Backdoor

In the 29th year of Kaiyuan, a frontier wall slices the Liu clan in two. Elder brother Liu Puqing exploits a deliberate gap in Tang law to legally seize his younger brother’s homestead, while the exiled younger sibling survives through a secret tunnel. When a disgraced magistrate arrives to adjudicate the case, he discovers the wall itself is a hidden backdoor—crafted by the capital's power brokers to turn legal loopholes into a land-grabbing machine. A historical suspense tale in the style of Kazuaki Takano, revealing that the most dangerous clauses are the ones written to be broken.
