The Western Xia spy agency, Ji Yi Siyi, was uprooted. The court also knew about the ambition of Li Deming, the lord of the Western Xia Kingdom, to become emperor, and Li Deming wanted to occupy Liangzhou and cut off the Silk Road, and at the same time made it impossible for the Song Dynasty to buy good horses in the Western Regions. Therefore, the Song Dynasty and the opposition did not allow this situation to occur, and at this time, the Guiyi Army who mastered Shazhou made Cao Xianshun come to worship and wanted to surrender. At this time, the war between Western Xia and Da Liao was in full swing, and because of the assassination of Yelu Yanni by Western Xia, it also aroused the greater anger of Da Liao. The Great Song Dynasty also had the excuse to send troops, and Liao Shengzong invited the Great Song Dynasty to send troops at this time. The Political Council and the Privy Council decided to send troops from Lanzhou to capture Liangzhou and Ganzhou to meet Shazhou, open up the Hexi Corridor, and restore the Silk Road. It was decided to send Chong Shiheng (985-1045) as the main general, and Zhi Weizhong (982-1033) as the deputy general to lead an army of 100,000 troops.

Meng Ming now knows that there are many branches of the party, and they are not monolithic, and the family is the party clan. On this expedition, the twenty-four-year-old General Yang Wenguang led the Yang family army to participate in the battle, and Meng Ming knew that Li Deming and Li Yuanhao, father and son, were also heroes and extremely difficult to deal with. Meng Ming prepared to rush to produce 1,300 flintlock pistols in a row, and reported the matter to the Privy Council, which approved the production immediately. Finally, it was made seven days before the expedition. Meng Ming called Yang Wenguang, I taught him to load ammunition, aim and shoot, and then let him test the gun, Yang Wenguang was stunned, he called this gun a "magic weapon". Archer training is troublesome, there are extremely high requirements for physical fitness, requiring strong arm strength, but also to master skills, the cultivation of a skilled archer takes about three years; And this gun is simple to operate, easy to train, can shoot in a day, and the time to master it should not exceed a month. Meng Ming told him again about the three-stage shooting method of the musket, which was almost the same as the three-stage design method of the bow and crossbow at this time. Yang Wenguang selected a thousand people to form a musket battalion, assault training for six days, each gun fired more than 100 times, each of them mastered the skills of shooting, Meng Ming designed a rope-pulling grenade, no more than a hundred, another 500 mines, also taught them to use. Meng Ming equipped Yang Wenguang with ample ammunition.

Yang Wenguang led the army to set off, to Lanzhou and the main force of the Song army to rendezvous, before leaving, Meng Ming gave Yang Wenguang a poem "Qinyuan Spring. Snow":"

The scenery of the northern country, thousands of miles of ice, thousands of miles of snow drifting. Looking inside and outside the Great Wall, only reckless; Up and down the river, suddenly lost and surging. Mountain dance silver snake, the original Chi wax elephant, want to be higher than the heavenly public test. It must be a sunny day, and look at the red dress, which is extraordinarily enchanting.

There are so many delicate rivers and mountains, leading countless heroes to bend their waists. Regret the Qin Emperor and Han Wu, slightly lose the literary style; Tang Zong Jin Zu is slightly less coquettish. A generation of Tianjiao, mourning the king of heaven, only knows how to bend the bow and shoot the eagle. The past, the number of romantic figures, but also look at the present. ”

Because Yang Wenguang led his troops to ride on horseback, and the grain and grass supply of the state capitals on the way, he rushed to Lanzhou in the first month of the second year of Tiansheng, and met with the commander Chong Shiheng and the deputy marshal Zhi Weizhong. Since most of Liangzhou had been occupied by the Ganzhou Uighurs in 1018, it had been four years; The area along the Yellow River in eastern Liangzhou had been swallowed up by the Western Xia. The Western Xia and Ganzhou Uighurs made a violent conquest of Liangzhou, which had caused the Liangzhou people to complain and have the heart to resist. Moreover, the local tyrant Re Kui's heart is towards the Great Song Dynasty, no, Chong Shiheng has sent a fine work to get in touch with his family. and got in touch with the last Liangzhou defense envoy Governor of Liangzhou. In the end, the two secretly went to Lanzhou and met with Chong Shiheng and Zhi Weizhong. The two of them reported to Chong Shiheng on the deployment of the Ganzhou Uighur generals and troops in Liangzhou, and after the meeting, the two sides drew up a detailed plan, agreeing that the interior and the outside should join forces to recover Liangzhou. Chong Shiheng asked for a seal on the table to the dragon and the priest.

On the twenty-sixth day of the first month, after some preparations, Chong Shiheng divided his troops into two attacks, led 40,000 elite soldiers, went out of Lanzhou, and marched northwest along the Karochuan River to capture Gaizhu; In addition, Zhi Weizhong led an army of 60,000 out of Huizhou and the city (Zhuo Luocheng), marched along the west bank of the Yellow River, attacked the Western Xia army in Liangzhou, and occupied the Great Wall; He also ordered the Huaide army and the Dingbian army to strictly guard against the surprise attack of the Western Xia army.

Half a month later, Chong Shiheng captured Jisang, led his army to repair, and prepared to capture Xiliangcheng, the capital of Liangzhou, three days later, with 5,000 Uighur soldiers. Chong Shiheng has sent a fine work to get in touch, and he agreed to open the city gate after the war to welcome the king. In the end, Chong Shiheng led the army to Xiliangcheng, and there was no fierce fighting, and the defenders of the Uighurs in Ganzhou surrendered, and it turned out that the defenders of the Uighurs in Ganzhou were a Han Chinese, named Zhang Daolian, after Zhang Yichao, the assassin of the late Tang Dynasty. After Zhang Daolian led the army to surrender, he came to meet Chong Shiheng, he bowed to Chong Shiheng and said: "Kind of handsome, the general Zhang Daolian has something to do, and Wang Shi has taken Xiliang Mansion." I am Shazhou Zhang, after Zhang Yichao, now Shazhou has been secretly controlled by the Ganzhou Uighurs, and the Guiyi Army has made Cao Xianshun almost a puppet, but most of the people of Shazhou are Han, or the heart is to the Cao family, the heart is to the Great Song Dynasty, please send troops to recover Shazhou, I am willing to be the vanguard. "After weighing it for a long time, after learning about the situation in Shazhou, you can send troops. Ganzhou was conquered in a few days, and Bingfeng pointed directly at Shazhou. The Uighur soldiers of Ganzhou in Shazhou were carefully scattered, but the Uighur generals drew their swords against the people in the city and surrounded the Cao and Zhang families, and many of the generals and soldiers of the Cao and Zhang families in the Shazhou garrison were also mostly Han Chinese. Therefore, the atrocities of the Uighur generals caused the Han generals to mutiny, and they pursued and killed the Uighur generals, and the Uighur generals were also beheaded. The city was re-controlled by the Cao family, and sent people to contact the army of the Northern Song Dynasty, and then the 10,000 people of the vanguard army Li Zhaoliang were stationed in Shazhou, at this time Shazhou since the end of the Tang Dynasty and the war of the Five Dynasties and Ten Kingdoms, has lost contact with the Central Plains for a hundred years, just like a long-lost child, finally found a way home. Shazhou has always been in the Central Plains Dynasty as the Zhengshuo, so back to the embrace of the Great Song Dynasty, the generals and people of Shazhou welcomed the arrival of the king, and they all celebrated.
