In the Hexi Corridor after the Anshi Rebellion, the yellow sand buried the glory of the Tang Dynasty, and also buried the secret of the famous general Xiao Jing's "collaboration with the enemy and treason." His son Xiao Che, a young man from Chang'an who carried the Wu Gou Sword on his back, found the bronze tripod military talisman left by his father in the ruins and a stele, and then embarked on the westward journey.
He climbed over the Qilian Snow, crossed the Mohe Yan Moraine, glimpsed the secret of the Demon Suppression Tower in the murals of the Thousand Buddha Cave, and rescued Tang Army prisoners of war in the Kunlun Jade Mine. Along the way, he forged a life-and-death friendship with Su Wan, a girl from the Lingnan Li tribe, and Azao, an orphan from the Beacon Tower. He also joined forces with Prince Yehu of Uighur and Princess Yong'an who endured humiliation to uncover the shocking secret agreement between Tubo Zampu and the Uighur nobles to carve up Hexi.
Wu's hook sword cut through the lonely smoke in the desert, and the bronze tripod awakened the remaining troops in Hexi. After becoming a soldier and making a secret promise, Xiao Che finally understood the bold loyalty behind his father's "submission of the enemy" - using his body as a bait to protect the mountains and rivers thousands of miles away. In the end, he led the rebel army to a decisive battle at Heyuan, and used the power of his lone sword to rekindle the banner of the Tang Dynasty. The wind under the Qilian Mountains is still telling a story about persistence and inheritance.
