"通过子孙获得繁荣，通过求爱获得征服"

Lu Chen, a soul yanked from another realm, plunged into the resplendent yet intricate Great Xia Dynasty, donning the mantle of the ninth prince. Unlike the stereotypical time-travelers painted in other sagas, he was devoid of the expected wealth of scientific and engineering wisdom and the vast repository of ancient poetic lore. With the express aim of dodging the perilous and cutthroat tussle for the imperial throne, he chose the path of indolence, hankering to bask in the luxury and comfort bestowed by his princely standing, far from the maw of political chaos.

Thanks to the status of his mother, the imperial concubine, Lu Chen's fate took a further swerve. The emperor, perhaps in a calculated act of kindness or a political gambit, granted him a matrimonial bond and then banished him to the desolate and frigid northern hinterlands as a prince. There, in that seemingly forsaken expanse, Lu Chen had all but resigned himself to a life of dwindling mediocrity and a slow fade into oblivion.

But destiny had other designs. On the very night of his nuptials, a cryptic and potent system sprang to life, crackling with latent might and untapped potential. This remarkable system proffered a unique and beguiling pledge: for each heir he sired, Lu Chen would be inundated with lavish rewards and witness a meteoric ascent in his personal prowess and capabilities.

Years rolled by, and the once-scorned and overlooked prince emerged from the northern mists, at the helm of a colossal army, a million strong, their banners fluttering in the wind as they marched with unwavering resolve towards the capital. The sight of this formidable force, led by the hitherto underestimated Lu Chen, sent shockwaves through the hearts and minds of all who beheld it. Whispers of disbelief and astonishment rippled through the onlookers: "Was he not the so-called 'worthless prince'? From where did he muster this legion of a million?"
