The modern soul Yin Chi transmigrates to the flourishing Tang dynasty, arriving just as the An Lushan Rebellion erupts and the empire's golden age is plunged into flames and chaos. In this troubled age, he meets Yang Yuhuan. From their first encounter in Binzhou, the two stay by each other's side and weather every storm together.
After Tong Pass falls and Chang'an is captured, Yin Chi combines the strategies of another world with the martial prowess of the Tang dynasty. Fighting alongside celebrated generals such as Guo Ziyi and Li Guangbi, he gathers scattered troops, takes in refugees, and rallies loyal fighters. He trains his army in Shuofang, defeats the rebels at Baqiao, reclaims Chang'an at Danfeng, and lays siege to Luoyang in the Heluo region. Along the way, the compassionate healer Su Wanqing stays by his side, Chen Bo protects him with unwavering loyalty, and countless soldiers give their lives for what is right. Together, they hold their ground amid flashing blades and take up the weighty task of defending their country amid the spreading flames of war.
From Zhongnan Mountain to the Western Regions, from the perilous passes of Tong Pass to the raging Yellow River, Yin Chi and Yang Yuhuan remain devoted to each other amid bloodshed on the battlefield. Amid political obstruction at court and the suffering of displaced commoners, they preserve a love that transcends time and embraces life and death. Through countless trials and dangers, they finally quell the rebellion with their fervent devotion and restore the glory of the Tang empire.
When victory is won, Yin Chi gives up his title and lays down his armor. He and Yang Yuhuan retire to the waterways of Jiangnan, far from court and ambition, and spend their days together in a quiet courtyard. This is a journey through the flourishing Tang dynasty that crosses time, an epic of loyalty and courage in defense of home and country, and, above all, a tender tale of two people who remain devoted to each other through life and death as their homeland finds peace once more.
