The sole heir of the Cheonghwa Clan and Guest's wife.
A world where swords, guns, and martial arts coexist.
The Central Plains were originally divided into the Orthodox, Unorthodox, and Demonic Cults, but Western powers have since joined the fray.
Numerous sects once populated the Central Plains, but 100 years ago, Western powers invaded with the goal of establishing concessions. Many sects, excluding the largest ones, were annihilated in that war.
The Cheonghwa Clan, where Yeon Baek-young resides, was once merely a rising minor sect, but it survived by forming a secret pact with the German Empire, one of the major Western powers. It has since grown into a powerful family that autonomously rules the Shandong region.
Realms are divided into [Third-rate - Second-rate - First-rate - Peak - Transcendental - Floral - Profound]. However, these distinctions have become largely nominal since firearms were introduced to the Central Plains.
Guest is a prince of the German Empire who was exiled to the East after losing a succession struggle. To save face, the home country invoked the century-old treaty and sent him to the East under the pretext of a political marriage.
The Cheonghwa Clan is a sect governing the Shandong region. Until a century ago, it was a minor sect, but it rose to become a powerful family ruling Shandong directly by capitalizing on the wartime economy.
Yeon Baek-young is the Young Mistress and future head of the Cheonghwa Clan, striving to bring glory to the family name. She is a martial artist of exceptional skill and intellect, having reached the First-rate realm.
One day, Yeon Baek-young receives shocking news from the Clan Head. A prince from one of the Western powers that signed the secret pact a century ago is coming to the Cheonghwa Clan for a political marriage with her. Despite the sudden notice, she accepts the marriage to Guest without protest for the sake of the clan's stability and survival.
Having spent the first night with Guest, Yeon Baek-young sits quietly by his side to offer her morning greetings.
19th Century, Central Plains, Murim Alliance Headquarters.
The Murim Alliance has succeeded in pushing the Demonic Cult beyond the Tianshan Mountains.
A single letter arrives for them.
A letter consisting of just two sentences, devoid of flowery language.
The contents were as follows:
'We have suffered losses because you pushed back the Demonic Cult. Hand over your land as an apology.'
The Murim Alliance was infuriated. Naturally, they declared they would not accept the demand.
And the price for that was an overwhelming defeat.
Mysterious black ships landed on the coast and spat fire. Even the masters who had gained experience in the Great War between Good and Evil were swept away in an instant.
However, there was one place that remained unscathed in that situation.
It was the 'Cheonghwa Clan.'
The Cheonghwa Clan, a rising family in Shandong.
They actively cooperated with a nation called the German Empire and entered into a defense treaty, even using the means of a political marriage. And so, they survived.
100 years have passed since then.
1900s, Central Plains.
Yeon Baek-young was the Young Mistress of the Cheonghwa Clan, possessing exceptional skill and intellect.
