At first, after the defeat of Feng Changqing's army, he sent envoys to the court three times to state the situation of the rebels, but Tang Xuanzong refused to meet him with anger.

So Feng Changqing personally rode into the court to report, and when he arrived in Weinan, Tang Xuanzong issued an edict to deprive him of his official position and title, and let him return to Gao Xianzhi's army as an ordinary soldier to serve his life.

Feng Changqingcao wrote a testament to Tang Xuanzong and said: "After I die, I hope Your Majesty will not despise the traitor An Lushan, and don't forget what I said!"

The reason why Feng Changqing warned Tang Xuanzong like this was because the courtiers at that time thought that An Lushan was arrogant and rebellious, and it would not take long to fail, and everyone was guilty of underestimating the enemy.

When Bian Lingcheng arrived at Tongguan, he first called Feng Changqing and announced the edict to him. Feng Changqing handed over his cursive testament to Bian Lingcheng and asked him to help present it to Tang Xuanzong. After Feng Changqing was killed, his body was placed on a thick mat and hastily thrown into the Chaofeng Gang.

When Gao Xianzhi returned to the official office from the barracks, Bian Lingcheng had already led more than 100 Mo Daomen to wait there, and he said to Gao Xianzhi: "The emperor also has a grace to Doctor Gao. ”

After hearing this, Gao Xianzhi immediately went down to the hall, and Bian Lingcheng announced the edict.

After the edict was read, Gao Xianzhi argued: "I met the rebels and retreated without resistance, and I should have died." But now that there is heaven and land, it is really unjust to say that I have stolen the soldiers' rations and materials. ”

At that time, Gao Xianzhi's subordinates were all present, and everyone shouted that Gao Xianzhi was wronged, and the roar shook the ground, but Bian Lingcheng still killed him. Then he ordered General Lee Seung-gwang to lead the army on his behalf.

Hexi, Longyou Jiedu made Ge Shuhan recuperate at home due to illness, Tang Xuanzong because he has a prestige, and has always had a discordant relationship with An Lushan, so he summoned him, worshiped as the deputy marshal of soldiers and horses, and led 80,000 troops to conquer An Lushan.

Tang Xuanzong also ordered troops to march from all over the country and gather troops to recover Luoyang. Ge Shuhan insisted on resigning due to illness, Xuanzong did not agree, and appointed Tian Liangqiu as the middle of the imperial history and the marching Sima, the living lang Xiao Xin as the judge, and the general of the Tibetan people, Huoba Guiren, etc., all led the tribal army under the command of Ge Shuhan, plus Gao Xianzhi's original army, numbered 200,000, guarding Tongtou.

Ge Shuhan couldn't take care of military affairs due to illness, so he entrusted all the major affairs of the military to Tian Liangqiu. Tian Liangqiu didn't dare to decide a major event alone, so he let Wang Sili lead the cavalry and Li Chengguang lead the infantry, and because these two fought for power, the military orders could not be unified. Geshuhan used harsh and inconsiderate soldiers, so the soldiers were lax-willed, demoralized, and ineffective.

An Lushan's general Datong Army made Gao Xiuyan lead his troops to invade the Zhenwu Army, but was repelled and defeated by Guo Ziyi, who took advantage of the victory to conquer the Jingbian Army.

An Lushan's Datong soldiers and horses made Xue Zhongyi invade the Jingbian army, Guo Ziyi sent the left soldiers and horses to make Li Guangbi, the right soldiers and horses to make Gao Jun, the left Wufeng to make Fugu Huaien (Fugu Huaien is the great-grandson of Brother Banyan, and has been the governor of Jinwei for generations), and the right Wufeng envoy Hun Shizhi (Hun Shizhi is the chief of the Hun tribe, and has been the governor of Gaolan for generations) and other troops to lead troops to meet the battle, defeating the rebels, and 7,000 cavalry were killed. Then he marched to surround Yunzhong County, and Guo Ziyi's faction led Gongsun Qiongyan with 2,000 cavalry to conquer Mayi and open the passage to Dongcheng Pass.

Jiachen (19th), Xuanzong crowned Guo Ziyi as the imperial historian.

Yan Gaoqing was ready to raise troops to fight against the An Lushan rebels, and Feng Qian, who joined the army, Jia Shen, the former Zhending County Commander, Cui Anshi, the county lieutenant of Gaocheng, Zhai Wande, a native of Changshan, and Zhang Tongyou, a Cheng Zhang Tongyou of Neiqiu County, all participated in the planning.

Yan Gaoqing sent someone to contact Taiyuan Yin Wang Chengye and asked him to also raise troops to respond. At this time, Yan Zhenqing secretly contacted Yan Gaoqing from the plains to send Yan Gaoqing's nephew Lu Ti, wanting to cut off An Lushan's back road with his troops and stop An Lushan's conspiracy to attack the capital westward.

At this time, An Lushan sent his Jinwu general Gao Miao to Youzhou to recruit troops, and before he returned, Yan Gaoqing summoned Li Qincao under the pretense of An Lushan's order and asked him to lead his subordinates to the county town to receive a reward.

On the 21st of Bingwu (21st), it was just dark, Li Qincao came to Changshan, Yan Gaoqing asked Yuan Juqian and Feng Qian and others to take wine, food, prostitution and pleasure to comfort, and his henchmen were drunk, so Yuan Luqian and others cut off Li Qincuo's head, seized his weapons, and tied up all his generals, killed them all the next day, and dismissed the rebels guarding Jingcheng Pass.

Soon, Gao Miao returned from Youzhou, and when he was about to arrive in Gaocheng, Yan Gaoqing sent Feng Qian to capture Gao Miao.

Nan reported that He Qianqian had come from Tokyo, and Cui Anshi and Zhai Wande rode to Liquanyi to meet him, and captured He Qianqian and were escorted to the county on the same day.

He Qianqian said to Yan Gaoqing: "Now you have to make every effort to maintain the world of the Tang Dynasty, even if you have a good start, you should also have a good result." The soldiers you have recruited in Changshan County are a rabble that will be difficult to resist the rebels, so you should dig deep and fortify them, and do not directly confront the elite of the rebels. After the troops from Shuofang Town arrived, they marched together and passed on Zhao County and Wei County, allowing them to attack at the same time, dividing and cutting off the connection between the Fanyang rebels. You should now declare: 'Li Guangbi has led 10,000 infantry and cavalry out of Jingshan. And let someone tell Zhang Xiancheng and said: "Most of the regiments you command are regimental training soldiers who do not have much combat effectiveness, and they do not have strong armor and fast swords, so it is difficult to resist the strong soldiers from Shanxi." In this way, Zhang Xiancheng will automatically break the siege and retreat. It's also a big deal. ”

Yan Gaoqing was overjoyed after hearing this, and after thinking about it carefully, the more he thought about it, the more he felt that He Qianqian's plan was feasible, so he acted according to He Qianqian's plan.

Zhang Xiancheng really retreated, and the regiment he led was also defeated.

So Yan Gaoqing sent people into Raoyang City to comfort the soldiers. He also ordered Cui Anshi to tell other prefectures and counties: "The imperial army has gone down to Jingcheng Pass, and it will arrive soon, and the prefectures and counties in Hebei will be pacified first." Those who return first will be rewarded, and those who come later will be killed!"

These words are very inspiring, and the states and counties in Hebei have responded, and a total of 17 counties have returned to the imperial court, with more than 200,000 troops. The rest of the rebels attached to An Lushan were only six counties, including Fanyang, Lulong, Miyun, Yuyang, Jijun and Yejun.

Yan Gaoqing secretly sent people into Fanyang City to recruit Jia Xun, at this time Ma Sui, a native of Jiacheng, advised Jia Xun: "An Lushan is ungrateful, raises troops to rebel, and acts rebelliously, although he occupies Luoyang, he will eventually be defeated." If you can kill the generals who are unwilling to join the imperial court, let Fan Yang return to the imperial court, and overthrow the lair of An Lushan rebels, it is equivalent to establishing an immortal feat. ”

Jia Xun thought that what he said was right, but he still had concerns in his heart, and he hesitated and did not act. This matter was known to his other general, Niu Runke, and secretly reported it to An Lushan, An Lushan was shocked when he heard this, and immediately sent his confidant Han Chaoyang to summon Jia Xun.

When Han Chaoyang arrived in Fanyang, he pretended to call Jia Xun to talk to him, took the opportunity to let the strong man strangle him, and exterminated his family, and then appointed the other general Niu Ting to lead Fan Yang's army. The rebel generals Shi Siming and Li Lijie led the Fan Han infantry and 10,000 cavalry to attack Boling and Changshan two counties. Ma Sui fled into Xishan and was hidden by the hermit Xu Yu to avoid death.
