Li Xian, a top student in the modern military industry, accidentally traveled through time and became a fake eunuch of the Prince's Mansion of the Wu Dynasty. The dynasty was on the verge of collapse, with powerful ministers inside the government in chaos and powerful enemies outside. In a desperate situation, he relied on his calligraphy skills from a scholarly family to overcome the danger of the firewood shed. He used modern military industry knowledge to improve bows and arrows, invent horseshoes, and forged artillery to defeat the enemy.
He promoted "technological governance", established a power structure of six ministries and the Embroidered God's Palace, used high salaries to support the integrity of the Qing Dynasty, and used cross-era technology to empower the people's livelihood and the military; he brought seven beauties together to face adversity, Queen Wei Mi was gentle and prudent, Zhaoyi was brave and good at fighting, Wu Yingluo was ingenious and creative, everyone worked together to help, and the harem was harmonious.
The Southern Wu Dynasty was stubbornly resisting, the Persians and the Japanese were coveting the secrets of firearms, the old nobles were secretly at work, and the aftermath of the troubled times was still unsolved. Li Xian used artillery as a shield and wisdom as a blade to level the south of the Yangtze River, expand the sea frontier, and defend against foreign enemies. He not only protected his people with iron and blood, but also protected his loved ones with tenderness. From palace intrigues to battlefield battles, from technological innovation to the foundation of a prosperous age, this legend that began in a desperate situation will eventually be in his hands, allowing the Dragon Flag of the Tang Dynasty to be planted all over the world, and civilization will shine through the ages.
