During the Zhenguan period of the Tang Dynasty, Xue Rengui from Jiangzhou, Shanxi, studied literature and martial arts under the master Li Jing since he was a child. He was gifted, had an amazing appetite, was extremely strong, and was chivalrous. When Xue Rengui was 18 years old, his parents died, his house was burned, and all his family property turned to ashes. When he was in poverty, Xue Rengui asked for help from his uncle but was rejected. Fortunately, he was rescued by Wang Maosheng and his wife. Xue and Wang became sworn brothers. Wang Maosheng introduced Xue Rengui to Liu Yuanwai's house as a coolie to make a living. Liu Yinhuan, the daughter of the Liu family, was moved by Xue Rengui's chivalrous feelings. She secretly helped Xue and fell in love with him. Despite her father's opposition, the two fled from Liu's house and got married in Han Yao. Emperor Taizong of Tang, Li Shimin, was hunted down by Bo Liao officials. When he was in danger, he was saved by a young general in white robes. It turned out to be a nightmare. Military strategist Xu Maogong interpreted the dream and said that the young general in white robes in the dream was the future pillar of the country. This "good minister who should dream" was Xue Rengui from Longmen County, Shanxi. Bo Jian, who was canonized as the King of Bo Liao by the Tang Dynasty, was instigated and coerced by the Grand Marshal Tie Shiwen. He was unwilling to stay in Bo Liao (now the Bohai Bay area in Liaoning) and wanted to get rid of the court, raise troops to rebel, establish himself as king, and dominate the Central Plains. In order to suppress the rebellion, Li Shimin decided to lead the army in person and recruit troops from all over the country. He ordered the general vanguard Zhang Shigui to recruit troops in Shanxi to find the "good minister who responded to the dream" Xue Rengui. The emperor Li Daozong had always had a grudge with Xu Maogong and other veterans of the Wagang faction. He was afraid that the "good minister who responded to the dream" would threaten his position, so he adopted the strategy of his beloved concubine Zhang Meiren and ordered his father-in-law Zhang Shigui to "win over Xue Rengui if he was close, and kill him if he was far away." Xue Rengui, who had just married and lived by shooting geese, signed up for the army under the guidance of his good friend Zhou Qing. However, due to the obstruction of the treacherous minister Zhang Shigui, the vanguard of the army, Xue Rengui had to join the army three times. Finally, with the help of Cheng Yaojin, Duke of Lu, he succeeded. However, he was assigned to the position of Huotou Army by Zhang Shigui. Although Xue Rengui was a man of both literary and military skills, he was a hero without a place to use his talents. He was bullied and framed by the treacherous Zhang Shigui, He Zongxian and Zhang Zhilong in the army. He went through hardships, but he was ambitious, endured humiliation and was able to bend and stretch. Princess Zhaoyang, the daughter of Prince Bo Jian, wanted to stop Bo Liao from raising troops to rebel against the Tang Dynasty, and had a grudge with Tie Shiwen, the Grand Marshal of the Bo Liao Army. Princess Zhaoyang failed to assassinate Tie Shiwen, so she had to sneak out of the palace with the peace agreement with Prince Bo Jian's intention and her maid Ling Cai'er, and went straight to the Tang Dynasty court. Luo Tong was conquered by Princess Zhaoyang's beauty and intended to serve her. He asked his uncle Cheng Yaojin for help so that Princess Zhaoyang could meet Li Shimin. Princess Zhaoyang was grateful to Luo Tong, but she had no intention of falling in love with him. Tie Shiwen learned that Princess Zhaoyang had come to the Tang court to negotiate peace, and sent assassins to chase her all the way. The princess met the bandit Li Qinghong in a panic. Li Qinghong wanted to capture Princess Zhaoyang as the wife of the village, but fortunately she was rescued by Xue Rengui, and from then on, Xue and Zhao fell in love. Xue Rengui successively subdued seven bandits including Li Qinghong, and became sworn brothers, and joined the army together. In the process of suppressing the Bohai Liao rebels, Xue Rengui was highly skilled in martial arts, led the fire army to open the way, was invincible, and repeatedly made extraordinary achievements, which was favored by Li Shimin. However, Zhang Shigui attributed all the credit to Xue Rengui's son-in-law He Zongxian, and designed "responding to the dream of the rebel minister" so that Xue Rengui dared not reveal his identity, and buried his name in the barracks as a fire army cooking. Li Shimin was eager to see the "honest minister who responded to the dream". According to the strategy of military advisor Xu Maogong, he used the "Dragon Gate Formation" and "Pingbo Theory" to test out the "honest minister who responded to the dream" in the army, but Zhang Shigui's fraud failed. Liu Yinhuan gave birth to twins, a boy named Xue Dingshan and a girl named Xue Jinlian. Yinhuan fully supported her husband Xue Rengui in suppressing the rebellion and defending the country for the Tang Dynasty, shouldered the burden of life, raised children with hardships, and was rescued by Wang Maosheng and his wife. On the way to suppress the rebellion, Li Shimin was besieged in Fenghuang Mountain by Marshal Tie Shiwen, and all the 26 generals who accompanied him on the road died in Tie Shiwen's "Nine Leaf Flying Knife". In order to solve the dilemma of Fenghuang Mountain, the fire head army was all poisoned by the centipede of Mei Li, the wife of Tie Shiwen. Although Princess Zhaoyang tried her best to save them, it was ineffective. Li Qinghong and Jiang Xingben died. Xue Rengui and other brothers were lucky to meet the master Li Jing who rescued them in time and escaped the disaster. At the same time, the Tang army was trapped in the empty city plan in Yuehucheng, Sanjiang. Fortunately, Qin Huaiyu and Luo Tong rushed to the city and saved the day. Xue Rengui recovered and took Fenghuang Mountain by force, saving the Tang emperor Li Shimin who was in distress. Tie Shiwen escaped from the battle. Xue Rengui led Zhou Qing and other fire troops to pursue the victory, and three arrows were used to conquer Tianshan Mountain, bravely breaking Motianling, and cleverly taking Baiyuguan. Tie Shiwen eventually died in Xue Rengui's "Dragon Gate Formation", and the rebels were annihilated. Zhang Shigui's conspiracy to steal credit and harm Xue Rengui was discovered by military advisor Xu Maogong. So Zhang Shigui murdered and wanted to burn Xue Rengui to death in Tianxian Valley, but Xue Rengui cleverly escaped. With the help of loyal ministers Xu Maogong, Cheng Yaojin, Yuchi Gong and others, Li Shimin finally met Xue Rengui, the "honorable minister who responded to the dream", and the truth came to light. Zhang Shigui's plot was exposed, and he started a rebellion and surrounded Chang'an. However, Xu Maogong planned and secretly sent Xue Rengui to Chang'an. Zhang Shigui was defeated and captured and sentenced to death. The rebellion was quelled and the world was unified. Li Shimin returned to the court and rewarded his merits. Xue Rengui was named the King of One Word and the Grand Marshal of the World's Recruiting Troops, and Zhou Qing and other fire soldiers were named the Imperial Generals. Xue Rengui returned home in glory and finally reunited with his wife Liu Yinhuan and his brother Wang Maosheng, who had been separated for thirteen years. Xue Rengui valued love and righteousness, and hired Wang Maosheng as the steward of the general's mansion. He also repaid grievances with virtue and treated his father-in-law Liu Yuanwai well. With the marriage granted by Tang Emperor Li Shimin and the communication of Yinhuan, Princess Zhaoyang also became Xue Rengui's wife. Zhang Meiren, the daughter of the traitor Zhang Shigui who was executed, and the favorite concubine of the emperor's uncle Li Daozong, wanted Li Daozong to avenge her father and brother. Li Daozong forged an imperial edict and set a trap to frame Xue Rengui, causing Xue Rengui to be thrown into prison...
