[Intangible inheritance + Marriage first, love later + Suspense adventure + Two-way redemption]
Su Yan thought that this marriage was just a transaction where each got what he wanted.
Until she discovered that the mysterious husband Shen Zeyu had half a lost dovetail tattooed on his wrist;
Until she saw the billionaire CEO in his study room late at night, silently shaving on century-old wood;
Until the missing corner of the Luban lock popped out the secret wood chip engraved with "Tongxin".
"In this era of fast food fixed with nails, I want to talk to you about a mortise-and-tenon type of love - no need for nails or glue, just the fit of the concave and convex, and it will last a lifetime."
However, behind the marriage contract is the underground secret room that the family has guarded for seventy years. It is the plunder of the capital giants, and it is a bloody past that has been sealed in the dust.
When the door of the old house's underground palace slowly opened, Su Yan understood:
He did not marry her, but the only "key" that could unlock the truth.
But when he looked at her and said, "It hurts, it hurts all the time," she knew that everything had changed.
The mortise and tenon are the engagement, and the rest of your life is the contract. Is this game a calamity or fate?
