On a winter night in Peking in 1927, Wang Feirong, the daughter of the Wang Bank, encountered the warlord Marshal Shi Dalong climbing over the wall and sneaking into his courtyard on the eve of his engagement party. This encounter, smelling of gunpowder, revealed the blood feud between two generations: the Shi family munitions case involved Wang's father's unjust enrichment, and the account book Shi Dalong was looking for was hidden in the secret compartment of Wang Feirong's ivory dressing box. When the cold barrel of the gun pressed against the waistline of the hibiscus-embroidered cheongsam, Lin Li, who was hiding deep in the west wing, set fire to the backyard granary. In the whirlpool of warlord rule and financial secret war, every confrontation between the two old enemies behind the red paint screen makes the love between Canary and Falcon more bloody. When the artillery fire from Forty-Nine City lit up the courtyard of the courtyard, Wang Feirong finally discovered that what Shi Dalong wanted was not only the Wang family's century-old foundation, but also her sincerity locked in the emerald longevity lock.
