In the twenty-third year of Zhenguan, Li Shimin, Emperor Taizong of the Tang Dynasty, passed away in the Hanfeng Palace. When he opened his eyes again, his soul traveled to Chongzhen, the last emperor of the Ming Dynasty who lived in the seventh year of the Apocalypse. Wei Zhongxian's power was overwhelming, the Liaodong war was raging, and Shaanxi was starved to death. In the civil and military affairs of the entire dynasty, no one is available; internal and external troubles, nothing can be alleviated. But he was Li Shimin - Li Shimin, who defeated an army of 100,000 with 3,500 cavalry in front of Hulao Pass, the founder of the Zhenguan rule. It took him three months to complete the journey of Chongzhen's life: purging the eunuchs, appointing capable ministers, and personally conquering Liaodong, and shooting down Huang Taiji with one arrow. Subsequently, the southward expedition to Annan, the westward expedition to Tianzhu, and the fleet reached the Indian Ocean pushed the Ming Dynasty's territory from the Liaodong grasslands all the way to the outside of the Persian Gulf. In the harem, Shen Yuzhu seamed the seams of the empire with pen and ink, Na Ren used her blade to suppress the embers of the grassland, and Sirindhorn, Ruan Yu, and Anura each applied what they learned to this new world that spans mountains and seas!
