Jiang Jiu, an orphan girl who writes family letters on the streets, becomes a substitute bride because of a brave act of justice. When she wakes up, she faces a coffin and chains. The cinnabar mole on the end of the eyebrow, which is regarded as a "brother-killing", became the key to the survival of Xiao Jiming, the second son of the Xiao family of the imperial merchants, and also involved her in a shocking conspiracy that spanned the family and the palace.
From the strange worship hall in an abandoned ancestral hall to the constant pursuit of escape, Jiang Jiu relied on his rebelliousness and wisdom to escape from desperate situations many times. Xiao Jiming's entanglement seems to be successful step by step, but in fact it hides an unknown guardian. The fire of the ghost furnace, the imprisonment of the Star Locking Tower, and the royal family's calculations. From testing each other to fighting side by side, the two exposed the hypocrisy of Tianshu Pavilion, the secrets of the Xiao family, and the blood debt of the royal family.
Using cinnabar as their blades and copper bells as their guides, they exchanged their lives for their lives and paid their debts with their blood. In the end, they overthrew the corrupt rules, forged new keys, and opened the fate platform, so that the world would no longer have shackles. This fetter that began with compulsion ended up being tempered in the flames of war into each other's salvation. Jiang Jiu also transformed from an orphan who couldn't help but transform into a swordsman in charge of his own destiny, carving out a piece of eternal freedom in troubled times.
