Geng Yan heard that Guangwudi (Liu Xiu) was halfway in Lunu, so he rode north to see Liu Xiu, who left him as an official under the account. Geng Yan took the opportunity to persuade You Zhu (official name) to go back and lead the troops to pacify Handan. Guangwudi smiled and said, "Children have such great ambitions!" So I summoned him and praised him. Geng Yan followed Emperor Guangwu northward to Jixian County (now Jixian County, Tianjin). I heard that Liu Ziyu's army in Handan is coming. Liu Xiu wants to go back to the south and call officials to discuss the plan. Geng Yan said, "Since the soldiers and horses came from the south, we shouldn't go south. Peng Long, the prefect of Yuyang, is your fellow countryman; Shanggu Taishou is my father. There are more than 10 thousand military forces in these two counties, so there is nothing to be afraid of. " Liu Xiu's confidant officials were unwilling to do so, saying, "Even if his head still faces south after his death, how can he be trapped in the north?" Liu Xiu pointed to Geng Yan and said, "He is our guide to the north." It coincided with the civil strife in Jixian County, and the officers and men were separated. Geng Ranyan went to Gengkuang in Changping, and persuaded Gengkuang to send Kou Xun to Chong Peng in the east, sending two thousand cavalry and one thousand infantry respectively. Geng Yan joined forces with soldiers from Single Crystal, Kou Xun, Yuyang and other places to go south, where he killed more than 400 officials under General Wang Lang Jiuqing and a captain, got 25 official seals/kloc-0, two batons, killed more than 30,000 soldiers, and settled 22 counties including Zhuo Jun, Zhongshan, Julu, Qinghe and Hexian. Soldiers met Emperor Guangwu in Guang 'an County. At that time, Emperor Guangwu was attacking Wang Lang, and it was widely rumored that military forces from Yuyang and Shanggu counties came to Handan to compete for Wang Lang, and they were all afraid. Then, they all entered Liu Xiu's barracks to meet Emperor Guangwu. Guangwu met Geng Yan and others and said, "We should share this great contribution with the officers and men in Yuyang and Shanggu counties." So he worshipped Geng Yan as a partial general, and asked him to lead Kibaki as well. Make Geng a general and a marquis of Xingyi, and you can build your own city. Geng Yan and others followed Liu Xiu and laid the foundation for Handan.
At that time, Emperor Geng (Liu Xuan) recruited Zhao Yong as the county magistrate, and Geng Kuang advised Zhao Yong not to do it, asking him to see Emperor Guangwu. Guangwudi also asked Zhao Yong to be the prefect of Dai Jun.. Zhao Yong returned to the north, but Zhang Ye, the chief of Daijun County, occupied Daicheng and rebelled, and recruited military forces from Xiongnu and Wuhuan as aid. Emperor Guangwu appointed Geng Yan's younger brother Geng Shu as a general and sent him to attack Zhang Ye, winning. Zhao was re-elected as the magistrate of the county. At that time, five factions of more than 200,000 bandits attacked Shanggu in the north. Geng Kuang and Uncle Geng were defeated one after another, and all the bandits retreated.
The Emperor (Liu Xuan) saw that Liu Xiu's fame was getting bigger and bigger, and he became suspicious of him, so he sent messengers to let Liu Xiu be Xiao Wang and told him to stop fighting and return to Chang 'an. Miao used to be the satrap of Youzhou (animal husbandry, official name), Wei Shun was the satrap of Shanggu and the satrap of Yuyang, and merged with the northern region. At that time, Liu lived in Handan Palace and lay in the hall during the day. Geng Yan went in to see Liu Xiuteng and asked him to take some time to talk. He said, "Turning over a new leaf now is political corruption, the monarch and the minister are promiscuous, the generals monopolize power in their respective territories, and the royal family and the state monopolize the capital. The life of the son of heaven can't spread outside the city, and local officials are always replaced. The people don't know who to listen to, and the officials are very upset. Everywhere people rob property, kidnap and rape women, go out with valuables, and it is impossible to come back alive. The world asks itself, it is worse than when Wang Mang was emperor. In addition, dozens of insurgents, such as bronze horses and red eyebrows, numbered millions, and the emperor could not cope again. Will soon be defeated and desperate. You set out from Nanyang and defeated millions of troops; Now the north of the Yellow River has been settled, occupying a rich land in the world. By conquering the emperor morally and giving orders, many people will respond and the world will soon settle down. Imperial power is the best in the world, and people with other surnames cannot be emperors. I heard that the angel of the emperor has come from the west and wants you to hand over the relieving. You can't obey. Nowadays, many officers and men have died and escaped. I am willing to go back to Youzhou and recruit more soldiers and horses to prepare for major events. " Liu Xiu was very happy, so he appointed Geng Yan as the general, and together with Wu Han from the north, he launched the military forces of ten counties in Youzhou. Geng Yan led troops to Shanggu, arrested Wei Shun and Cai Chong and killed them. Liu Xiu also killed Miao Zeng. So he launched the whole army of Youzhou, led troops south, followed Guangwu Emperor Liu Xiu to attack the bronze horse, the high lake, the red eyebrow and the green calf, pursued Youzhou, the cannon and the Five Banners, and won in Yuanshi County (place name). Geng Yan often personally led the burly cavalry to take the lead and disperse and defeat the enemy. Liu Xiu pursued the victory and began to fight along the river. The enemy is in a critical situation and still stubbornly resists. At this time, Liu Xiu's sergeant was exhausted, and finally he was defeated and ran away. He stuck to Fan Yangcheng. It took several days to cheer up and the enemy retreated. Geng Yan followed Liu Xiu's pursuer to Rongcheng, Yang Xiaoguang and Anci, and suffered heavy losses in succession. Back in Jixian County, Geng Yan, Han Yu, Monocrystal, Gaiyan, You Zhu, Tong Pi, Geng Chun, Herry Liu, Cen Peng, Ji Zun, Jane, Wang Ba, Chen Jun, Ma Wu and other 13 generals led troops to Pinggu, east of Liuhe. After that, the whole army wiped out more than 13 thousand people and chased them to the right of Peiping. The enemy fled to western Liaoning and eastern Liaoning respectively, and some of them were attacked by ethnic minorities such as Wuhuan and Qie, and almost all of them were wiped out.
Guangwu Emperor Liu Xiu acceded to the throne, and worshipped Geng Yan as general Jianwei. The ancient generals in title of generals in ancient times, Single Crystal, and the general with a strong crossbow, Jun Chen, attacked bandits who were tired of new ideas in Aocang and launched a war. Both of them were defeated and forced to surrender. In the second year of Jianwu, it was named Haohou, which governed Qi Hao and Yangmei counties. In the third year of Jianwu, Yan Cen attacked Nanyang from Wuguan and captured several cities. Du Hong, a native of Anxian County, led many people to take refuge. Geng Yan, Cen Yan and others were fighting in Rang County, and Geng Yan won a great victory, destroying more than 3,000 enemies, capturing more than 5,000 enemy officers and soldiers alive, and capturing more than 300 seals alive. Du Hong surrendered, and Yan Cen fled to Dongyang with several cavalry.
Geng Yan followed Emperor Guangwu to the mausoleum, requesting to assemble the military forces in Shanggu County in the north, go to Yuyang to pacify Penglong, go to attack, come back to recover Fuping and Suo, and attack Zhang Bu to pacify Qi and other places in the east. Guangwudi thought he was courageous and allowed it. In the fourth year of Jianwu, Geng Yan was ordered to attack Yuyang. Because his father is in the valley, Geng Yan has the same credit as Chong Peng, and he has no brothers in the capital. He was afraid of being suspected by the emperor and dared not March alone. He wrote to the court and asked to see the emperor in Luoyang. The court document was handed down and said, "General, your whole family is serving the country. Where the enemy is defeated, there is the greatest contribution. Why be an official in the DPRK? You and Wang Chang are temporarily stationed in Zhuo Jun, trying to break the enemy. " When Geng heard that Geng Yan requested to enter the DPRK, he was very uneasy, so he sent Geng Guo, the younger brother of Geng Shu, into the DPRK to serve Guangwudi. Guangwudi appreciated his practice, and added Geng's condition to the situation of the elk. So Geng Yan was ordered to attack Wang Du with Jianyi General You Zhu and Hanzhong General Wang Chang, so more than a dozen bandits' barracks of Anxi Mountain King were all taken. At this time, the conqueror General Ji Zun was stationed in Liangxiang, and Xiaoqi let Che Liuxi be stationed in Xiang Yang, ready to resist Chong Peng. Chong Peng sent his younger brother Peng Chun to lead more than 2,000 people in tarquin, and Chong Peng personally led tens of thousands of foot soldiers to attack Ji Zun and Liu Xi in two ways. Tarkan passes through the military capital. Uncle Geng broke through their camp and captured two Xiongnu leaders. Chong Peng then retreated. Geng Kuang and Uncle Geng attacked Chong Peng again and occupied the capital. After five years of Jianwu, he died. In order to reward Geng's contribution, the emperor sent Dr. Guanglu to greet Geng with a scepter and gave him a mansion with generous treatment. Shu was named Mouping Hou. Geng Yan and haing s ngor were sent to attack the captured bandits in Fuping. They fought in the plain and won a great victory. More than 40,000 enemies surrendered.
Emperor Guangwu ordered Geng Yan to conquer Zhang Bu again. Geng Yan summoned all the soldiers who surrendered, formed troops, appointed generals, and ordered Liu Xin, a surname, and Jun Chen, the Taishou of Mount Tai, to lead Ma Xiangdong across the Yellow River from Chaoyang Bridge. When Zhang Bu heard about it, he ordered his general city to be stationed in Lixia (now Jinan, Shandong Province), and then he divided his troops to be stationed in Zhuan Xu, and camped in the middle of Mount Tai, waiting for an opportunity to fight Geng Yan. Geng Yan crossed the Yellow River to attack Zhua first, and began to attack the city in the morning. Less than noon, he shot down, deliberately relaxed a corner of the encirclement, and let Zhang Bu escape to Zhong Cheng under Zhu's men. When people in Midtown heard that Zhu A had been captured, they were all scared and fled. Fei Yi sent troops to send his younger brother Fei Gan to stay behind Juli. Geng Yan's invasion first threatened Juli, causing people to cut down a lot of trees and spread the word to fill trenches and cities. A few days later, the surrenders reported that Fei Yi had heard that Geng Yan was going to attack Julius and was planning to reinforce Julius. Geng Yan ordered the soldiers to build siege equipment quickly, and announced that the whole army would concentrate on attacking Juli City within three days. Those who reported to Fei Yi from Julie were deliberately left behind so that they could reach Fei Yi. People who came back told Fei Yi the date of Geng Yan's attack on Juli. On that day, Fei Yi personally led more than 30,000 soldiers to save Juli. Geng Yan was so happy that many generals said, "I made siege equipment to lure Fei Yi here. Now that he has come, he has just fallen into my trap. " So he sent 3,000 troops to besiege Juli, personally led a good soldier to ambush in kasaka, and fought against the enemy with higher terrain, and won a great victory, killing Fei Yi in the battle. Then hang Fei Yi's head and show it to Juli City. Very scared in the city, Fei dared to take refuge in Zhang Bu with all his troops. Geng Yan seized the property accumulated by Fei Gan, commanded the army to attack those enemies who did not surrender, and destroyed more than 40 military camps, thus pacifying Jinan.
At that time, Zhang Bu established the capital in Drama County, and ordered his younger brother Zhang Lan to lead more than 20,000 soldiers to be stationed in Xi 'an. The satrap of each county is always stationed in Linzi, 40 miles apart. Geng Yan strode into the painting and was stationed between Xi 'an and Linzi. Geng Yan observed that Xi 'an was small, but strong and difficult to attack, and Zhang Lan's military strength was strong. Although Linzi was actually easy to attack, he spread the news at the general meeting and attacked Xi 'an in five days. Zhang Lan, after hearing this, held on carefully from morning till night. In the middle of the night, Geng Yan ordered his men to eat and drink, and waited until dawn before the team drove to Linzi City. Defender Xun Liang and others argued with Geng Yan that they should attack Xi 'an quickly. Geng Yan said, "No way. Xi' an heard that we were going to attack it, and we prepared all day; A surprise attack on Linzi will definitely surprise them. One day is enough for me to attack Linzi. With the laying of Linzi, Xi 'an will have no foreign aid, and Zhang Lan and Zhang Bu will be cut off, which will inevitably lead to no escape. This is the so-called plan to kill two birds with one stone. If we attack Xi first, we can't take it right away. The enemy is lean and the city is strong, and our army will suffer heavy casualties. Even if it can be shot down, Zhang Lan led the areas to flee to Linzi, meet Zhang Bu's troops, and observe our actual situation. We went deep into enemy-occupied areas, and there was no food and grass supply behind us. It won't be long before we get into trouble before the war. What you said is not appropriate. "So he attacked Linzi, and after a long time, he shot down and entered the city. Zhang Lan was very scared when he heard that, so he took his hand to the drama county next time.
Geng Yan then ordered the troops not to attack the theater county privately, and waited until Zhang Bu came to fight again to provoke Zhang Bu. Zhang Bu laughed and said, "I easily defeated hundreds of thousands of troops from Youlai and Datong. Now Geng Yan is less powerful than Youlai and Datong, and they are all exhausted. What's terrible! " So Chongyi, with his three younger brothers Zhang Lan, Zhang Hong, Zhang Shou and a former commander of Datong River, led an army of 200,000 people and drove to the east of Linzi to attack Geng Yan. Geng Yan took the lead in crossing Zishui, and joined forces with big differences. The cavalry wanted to charge. Geng Yan was afraid of losing Zhang Bu's momentum, so he didn't dare to March in the future. He deliberately confused him with his difference and weakness, so he led the troops back to Linzi Town. Zhang Bu's morale was high, and he went straight to Geng Yan's camp, fighting Liu Xin and others. Geng Yan climbed up the dilapidated balcony of the palace and observed Liu Xin's confrontation with the enemy. Suddenly, he led a good soldier to appear under the east side, set up his position and won a great victory. The arrow hit Geng Yan's thigh, and Geng Yan cut it with his sword. The people next to him didn't find it until evening. The next morning, Geng Yan ordered troops out again. Guangwudi was in Shandong area at that time. He heard that Geng Yan was attacked by Zhang Bu and came to save Geng Yan himself, but he hasn't arrived yet. Jun Chen said to Geng Yan: "The enemy's strength is very strong. We can take a temporary truce to raise troops and wait for the arrival of the emperor." Geng Yan said, "The emperor's chariots and horses will arrive soon. We courtiers should entertain officials with celebration wine. Should we leave these enemies to the emperor? " So he sent troops to fight again, and from morning till night, he defeated the enemy and suffered numerous casualties. The trenches in the city are full of bodies and wounded soldiers. Geng Yan expected that Zhang Bu would retreat when he was sleepy, and waited for him in ambush on the left and right wings in advance. At the appointed time, Zhang Bu really retreated, and the troops in ambush suddenly rushed out, chasing after them all the way to Jumei River. The road of eight or nine miles was full of bodies, and more than two thousand cars were seized as trophies. Zhang Bu returned to the drama county, and their brothers led the troops to disperse.
A few days later, the emperor arrived in Linzi to personally reward the army and gather the monarch and subjects. Emperor Guangwu said to Geng Yan, "In the past, Han Xin broke through the Li Dynasty and created the inheritance of the Han Dynasty. Today, you captured Zhu A and laid the foundation for development. Both of them are the western boundary of Qi, and you have contributed a lot. However, Han Xin attacked the surrendered troops. General, you have defeated Qiang Bing's mortal enemy. Get this credit, more difficult than Han Xin. A long time ago, Tian Heng cooked in a frying pan and killed Li Sheng. When Tian Heng surrendered, Emperor Gaozu ordered the state of Wei not to make trouble for Tian Heng, but he did not listen, and forged a vendetta with Tian Heng. Zhang Bu killed Long Fu before. If Zhang Bu comes to surrender, I will send Da Situ to pardon him, so you should treat him as a colleague. General, you suggested this plan in Nanyang before. I often think it is not easy to do it. I didn't expect to succeed in the end! " Geng Yan continued to pursue Zhang Bu, and Zhang Bu fled to Shou Ping. Finally, he walked outside the camp with a knife and an axe on his back. Geng Yan detained Zhang Bu, sent him to Guangwudi's mansion, and commanded the army to occupy Shouping City. Set up the banner of twelve counties, ordered Zhang Bu's soldiers to settle down in which county they belonged, and got more than 100,000 war horses and more than 7,000 chariots, provisions and munitions, dismissed them and sent them back to their hometown. Geng Yan then led the army to Chengyang to subdue the remnants of the five factions, and the Qi area was pacified. Return to Beijing with high morale troops.
In the sixth year of Jianwu, he sent troops to attack Xiao Wei in the west and stationed in Qixian County. In the eighth year of Jianwu, he followed the emperor to Gansu. In the second year, and the corps commander came to lead the troops to conquer Anding, Beidi and other cities respectively, and all won the victory.
Geng Yan has pacified 46 counties and more than 300 slaughterhouses, and none of them has suffered setbacks.
In the twelfth year of Jianwu, Geng fell ill, and the emperor personally visited him several times. Geng Guang and Geng Ju, the younger brothers of Geng Guo, were appointed corps commanders. Geng Yan's six brothers all carry blue and purple cloth bags to serve their father Geng's illness and take medicine. People thought they were honored at that time. After the death of Geng Kuang, posthumous title became a "fierce marquis", and his youngest son Geng Ba inherited the title of Geng Kuang.
In the 13th year of Jianwu, Geng Yan was promoted to several cities, handed over to general print, removed from the general's office, and was conferred as a rank by the imperial court. Whenever there was a local unrest, the emperor sent someone to ask for his advice. Geng Yan lived to be 56 years old and died in the first year of Yongping. Posthumous title's name is Cheng Hou.
