Xiao Yan, the marquis who was wronged, was seriously injured and exiled in Xinghua Village. The medical girl Lin Wanyi used herself as a shield, stained with blood under the arrow, and called him back with fireworks and whispers in the thin line between life and death.

When the gunpowder smoke clears, this world of fireworks, where each other is guarded by life and watered by sweat, is the Chang'an where they have endured hardships and have been dependent on each other for the rest of their lives.
