In April of the fifth year of Xingzhi, in order to relieve the siege of Yumen Pass, the Tang Dynasty Song Dynasty, Tian Bu, and Sha Zha led more than 6,000 elite raids on Shang Tazan who was besieging Yumen Pass, * to attack more with less, multi-way breakthrough, and want to reinforce the Shang Tazan Department of Ganzhou to start a fierce battle, the battle to the afternoon, the Tubo army was numerous, gradually gained the upper hand, suddenly the wind and clouds suddenly changed, the sand and dust came all over the sky, the northern desert thief Sha Wuji led more than 1,000 cavalry to brave the wind and sand, and the Song Dynasty Tian Bu arranged five hundred doubtful soldiers on the other side of the Hulu River, Shang Tazan did not distinguish the true from the false, thought that * was so big, led the crowd to flee, retreat to Jinguan, the siege of Yumen Pass was lifted.

At the beginning of May, after paying a heavy price, Li Guangyan's army finally annihilated Ganzhou and Tubo in Zhangye, and led the main force to Yumen Pass to recover Guazhou. Shang Tazan led his troops back to Yizhou, and at this point, the Battle of Hexi ended, and Hexi was recovered. Li Guangyan announced the emperor's edict, and promoted Shi Jingfeng to the champion guerrilla general, the Yumen Army and the Doulu Army's soldiers and horses, and Shi Jingfeng asked Li Jiyan to be the Yumen Army's soldiers and horses, and led the Doulu Army's soldiers and horses himself. Sha Wuji, Zhang's father and son, as well as Li, Suo and other Shazhou gentry were all rewarded. The Song Dynasty, Tian Bu, and Sha Cha Li all made several decisions and left them to the military department to discuss their merits. Li Yu issued an edict to select 100 sons from good families in Shazhou and Guazhou to go to Chang'an to enroll, and the Zhang Yitan brothers were among them and entered martial arts.

Sha Tuo suffered huge casualties in the Battle of Yumen Pass, Li Guangyan was originally from Turkic origin, and he had compassion for him, and wrote a letter to Sha Tuo to return to his hometown in Ganzhou. Li Chanted:

"I heard that Shatuo's residence in Ganzhou is just a matter after Guangde, if you want to move back to your hometown, don't you want to move back to the Jinshan Desert?"

Despite this, it is still divided into two parts, one lives in Wude Qianshan, with Sha Chali as the governor, and the other still lives in Yinshan, with Zhu Xie Chixin as the governor.

In June, after more than half a year of siege, Hao Jue took advantage of the rainy season to build a dam to store water in the upper reaches of Huangshui, preparing for water irrigation in Shanzhou. Unexpectedly, it was taken by the Tubo reinforcements out of Shibao City, and the sneak attack was successful, * I thought that the general situation had been decided, and I neglected to take precautions, and suffered heavy losses, so the general Li Wentong of Zuo Wuwei was killed in an arrow, and the general Ye Shiliangfu was seriously injured, Hao Yu had to lead his troops to retreat, and the loss of military funds was not calculated, and Kuozhou was also recaptured by the Tubo people. Fortunately, at first, Hao Wei and Li Wentong were both stable and steady, and built a continuous fortress, so that they could breathe. Shanzhou was originally the station of the Longyou Jiedu envoy, Hao Xuan was to conquer Shanzhou and then open the government to build teeth, this defeat, Hao Xuan felt that he had no face, and wrote to ask for guilt.

When the Qing nobles heard that Hao Jue wanted to flood the city with water but failed, they thought that it would hurt the peace of heaven, so they wrote to impeach Hao Xuan one after another, suggesting that Li Yu replace him, and by the way, Li Chun, the generalissimo of Taiwan, was also quite criticized. Li Yu thought that it was not appropriate to kill the general for the sake of the First World War, and insisted on his own opinion, but he just dismissed Deputy Marshal Hao Yu and let him make meritorious contributions. Hao Wei built Shanzhou in the lower reaches of the Huangshui River to show his determination to recover Shanzhou. He also wrote that the two armies had their own commanders, and that the failure to unify command was the cause of failure, and suggested that the left and right armies should be under the command of one person. The court thought it was impossible, but Li Yu issued an edict to abandon the left and right roads, and assigned Wang Maoyuan, Li You, Bai Zuwang and other troops to Hao Yu's command, and ordered Qiu Liangfu and Du Dare to lead their headquarters to Shanzhou for reinforcements. Ordered Li Guangyan to divide his troops out of the Heihe River valley and contain the Tubo army from the flank. Li Guangyan then ordered Cui Chengdu to lead the army out of the valley.

Hao Xuan received five strong reinforcements in a row, * the momentum was restored, and after resting for February, he led the army to Shanzhou again in September of the fifth year of Xingzhi. First, he broke the Tubo army at the foot of Qilian Mountain, and then besieged Shanzhou. In April next year, * dug tunnels, put gunpowder under the city walls, blew up the city walls, and attacked Shanzhou. Tens of thousands of people died in the battle below Tibet. In June, Hao Yu recovered Longyou, attacked the stone fort city, collected troops and returned, and officially opened the government office.

In July, Fan Xichao, the general of the auxiliary state and the commander of the Zuolong Wu army, fell ill and died. When the bad news came back to Chang'an, Li Yu cried bitterly:

"I originally wanted to drink with the military commander after the restoration of the Northwest Court, but I didn't expect that the sky would not be a holiday, how could I be embarrassed?"

Gift to the prince and master of Fan Xichao, he was loyal to Wu, and later changed to Xuanwu.

In the winter of November, the late prime minister, Du You, who guarded the Taibao and raised the hall of Jingshi University, passed away at the age of 80. Du You died in his sleep, and the day before he sighed:

"If Jia Gong (Jia Tan) knows underground, he will envy me for living to this day."

When Fan Xichao died of illness, Li Yu ignored the hot weather and went to Fan's Mansion to mourn. When Du You also went, Li Yu was a little bored in the palace. The crown prince, who had just returned to Beijing, was ordered to mourn for Li Chen. Pei Du came to the Zichen Hall to perform, and when he saw that Li Yu was unhappy, he knew that Li Yu was sad about Du You's death, so he comforted:

"Du Taibao's life is full of merits, virtue, speech, and meritorious service, and his three sons and ten grandchildren are all talents, and His Majesty should be happy for him."

The charcoal fire in the hall was very high, but Li Yan's heart was like the snow outside, and he sighed coldly:

"At the beginning of my succession, I was forced by my ministers, and this old man and General Fan had the merit of supporting me. After I eradicated the traitorous eunuchs, General Fan guarded Shuofang for me, and Du Xianggong planned internal affairs for me. In the past two days, I have even been thinking, these two elders have left me one after another, isn't it not far off that the time for me to go on a great trip? ”

Panicked, Pei Du hurriedly knelt down and said:

"Your Majesty is in his youth, so why should he say these unlucky words? If the minister is careless in his words, please punish His Majesty. ”

Seeing that Pei Du was so frightened, Li Yu smiled instead and said:

"Pei Aiqing is familiar with the scriptures and history, can she know that there are immortal emperors in the world? (Where does Pei Du dare to say?) Is Du Xianggong's nickname ready? ”

Pei Du Dao:

"Preparation."

Li Yu smiled:

"On that day, there will be no escape on that day. The so-called immortality is all nothingness, birth, old age, sickness and death are the reality of life, although I am an emperor, it is inevitable that there will be that day. Pei Aiqing, if that day really comes, what do you think they will add to me? ”

Seeing that he really couldn't hide, Pei Du thought for a while and said:

"Your Majesty's Shenwen Shengwu, turning the tide of the tide, reviving the Tang Dynasty, opening a prosperous generation, the minister thought that he could barely use 'Xuan'."
