Melody of Vibrant Iron Raiment

In the fifth year of Xianqing reign of Emperor Gaozong of Tang Dynasty (660 AD), Su Dingfang, the commander-in-chief of the Shenqiu Road Army of Tang Dynasty, led his troops across the sea to destroy Baekje, captured King Uija of Baekje alive, and established the Xiongjin Military Governor's Office of the Tang Dynasty in the homeland of Baekje, forming a pincer attack on Goguryeo from the north and the south. Since the seventh year of Daye (605 AD) when Emperor Yang of Sui Dynasty sent troops to conquer Liao, the campaign against Liao, which had lasted for more than half a century, finally saw the dawn of victory.

However, just as Su Dingfang presented the Baekje royal family as captives to Chang'an, war broke out in Baekje. The royal family's nephew Guishi Fuxin and the monk Daochen brought back the hostage Prince Buyeo Fengzhang from Japan and launched a movement to restore the country. The Japanese also took the opportunity to send troops to the peninsula in an attempt to recover the homeland of the "Four Counties of Mimana". The famous general Wang Wendu, who took over as the governor of Xiongjin, died of a sudden illness just after getting off the ship. The ally Silla had an ambiguous attitude, and the Tang Dynasty's rule in Baekje was in jeopardy.

At this critical juncture of life and death, Wang Wenzuo, a time traveler from a thousand years later, turned the tide and fulfilled the long-cherished wish of several generations of monarchs in the Sui and Tang dynasties. He avenged the deaths of hundreds of thousands of his brothers and sisters in the Central Plains and turned the land of Haidong into the territory of the Tang Dynasty. But all this was just the beginning, and the world was heading towards another path.
