"Her palm hid the game that he spent his whole life trying to solve, and his life was the only omission in her calculations."
Ten years after the Tiangong Pavilion was destroyed, the mechanical genius "Su Ci" concealed his name and disguised himself as a man to live in Yizhuang. A corpse with a hidden deadly mechanism involved her in a series of murders, which also attracted the pursuit of "Xiao Yan", the young minister of Dali Temple - the powerful "Jade Faced Yama" who actually saw through her disguise and knew the secret skills left by her father.
If the bronze bell rings, someone will die.
Each corpse holds a cinnabar soul-locking talisman in its palm, and a life-threatening bell hidden in its throat. Su Ci was forced to cooperate with Xiao Yan to investigate the case, but found out:
The mints in his sleeves taste exactly like her childhood hobby;
The scar under his collarbone was actually caused by the Su family's unique mechanism;
And when he chuckled and called her "porcelain doll", he looked very much like her fiancé who should have died in the fire long ago.
When the truth turns like gears:
The "Book of Lu Gong's Legacy" that the court forces are fighting over is actually a living machine diagram stabbed on her back;
The reason why Xiao Yan risked his life to protect her was hidden in the encounter she had forgotten in the fire scene three years ago...
"Su Ci, every trap you have demolished is my deliberate way to get closer to you."
Concept: Every murder is a mechanical puzzle to be solved
