In his early years, he and his cousin assisted Liu Xuan and Liu Xiu brothers in raising troops, and were one of the thirteen cavalry who broke through the Kunyang WarAfter that, he betrayed the Liu brothers and switched to the account of Liu Xuan, the first emperor, and even advocated killing Liu Xuan, and when the first regime collapsed, he wanted to take refuge in Liu Bei, and repeated it all his life. In 25 AD, Li Yi was killed by Zhu Kun.
Biography of the characterChung Ling raised troopsThe Li family is a powerful surname in Nanyang, Li Yi's uncle Li Shou is Wang Mang's Zongqing teacher, and Li Yi's cousin Li Tong has also served as General Wuwei and other official positions. In 22 A.D. (the third year of the emperor), the Green Forest Army uprising broke out, Nanyang was in turmoil, Li Tong because of the prophecy that circulated at that time said that "Liu's revival, Li is supplemented", he also had the idea of raising troops, because Li Yi has always been a good person, Li Tong brought Li Yi to discuss the matter together. Li Yi said to Li Tong: "Now that the Quartet is disturbed, Wang Mang's regime is about to collapse, and the Han Dynasty is about to be revived." Among the Liu clan in Nanyang, only the brothers Liu Xuan and Liu Xiu can love and accommodate Haojie, and the Li family can conspire with them to destroy Wang Mang and rejuvenate the Han Dynasty. Li Tong smiled and said, "My opinion is the same. Soon, Liu Xiu came to Wancheng to hide because he was evading the pursuit of officials, and Li Yi came to Liu Xiu to discuss major matters on the order of Li Tong, and the two sides hit it off and decided to raise troops at the same time. Subsequently, Li Yi returned to Chungling with Liu Xiu and prepared to raise troops. After Li Yi left, because the plan to raise troops was leaked, Li's clansmen in Chang'an and Wancheng were hunted down and killed by officers and soldiers, and they were almost wiped out. In October of 22 A.D. (the third year of the emperor), Li Yi, who escaped the difficulty of destroying the door, raised troops with the Liu brothers in Lingling, and it was not until he participated in the battle against Jianyang that Li Yi reunited with Li Tong, who escaped from Wancheng. **Liu XuanAt that time, the Green Forest Army was very powerful, and the strength of Liu Xuan and Liu Xiu brothers was relatively weak, so Li Yi abandoned the friendship of raising troops together and began to desperately curry favor with Zhu Kun and other Green Forest Army generals. In February 23 A.D. (the fourth year of Emperor Xinmangdi, the first year of Liu Xuan's change), the Green Forest Army supported Liu Xuan as the emperor and established the first regime, and Li Yi was appointed as the general of Wuwei. In May, the new dynasty army under the command of Wang Yi and Wang Xun surrounded Kunyang under the control of the Green Forest Army, and the Battle of Kunyang broke out. In the face of a strong enemy, Liu Xiu, Zong Tong, Li Yi and other thirteen cavalry broke through the encirclement, went to move the rescue troops, and finally attacked inside and outside, breaking the enemy army. After the Kunyang War, due to the prestige of Liu Xuan and Liu Xiu brothers, it became louder and louder, and the contradictions between the Liu brothers and the generals of the Green Forest Army became bigger and bigger. Liu Xiu was keenly aware of Li Yi's changes, and Liu Xiu said to Liu Xiu: "Li Yi can no longer be trusted. But Liu Xuan didn't take it to heart. Soon after, under the repeated advice of Li Yi and Zhu Kun, Liu Xuan took the opportunity to kill Liu Xuan. 
The upstart of the imperial courtIn February 24 A.D. (the second year of the change), after Liu Xuan moved the capital to Chang'an, he broke the ancestral training of Liu Bang, the ancestor of the Han Dynasty, and sealed thirteen kings with different surnames, among which Li Tong was named the king of Xiping;Li Yi was named the King of Wuyin, and their other cousin, Li Song, became prime minister. For a while, the Li family was in a high position and became a hot upstart in the imperial court. After being crowned king, Liu Xuan ordered Li Yi, the king of Wuyin, to preside over the recruitment of various counties, and in order to keep his position, the ** from all over the country visited Li Yi one after another, and wanted to see Li Yi, so he had to wait for a long time. Geng Chun, the son of Geng Ai, the Taishou of Jinan, also came to visit Li Yi, and when he saw this scene, he advised Li Yi, he said: "The king with the majestic posture of the dragon and tiger, when the wind and clouds meet, quickly rise from the ground, and the brothers are called kings in January, but the people do not know what virtues you have, and you do not preach any merits to the people, and grace and official positions are prosperous, which is taboo for the wise." Conscientious and vigilant and self-controlled, I am afraid that there will be no good end, let alone a sudden outbreak and self-sufficiency, can it be successful?Li Yi listened to Geng Chun's words and felt that what Geng Chun said made sense, and arranged for Geng Chun to be an official, but he did not listen to Geng Chun's advice. Secretly communicate with Feng YiJust when Li Yizhi was complacent, a news came from Hebei: Liu Xiu had swept Hebei and had a tendency to move west to Chang'an. In order to guard against Liu Xiu's attack, in the winter and December of 24 A.D. (the first two years of the change), Liu Xuan sent Zhu Kun, Li Yi, Tian Li, Chen Qiao and others to lead an army of 300,000 to build a Central Plains defense system with Luoyang as the center. Liu Xiu appointed Feng Yi as the general of Mengjin, and led the soldiers and horses of Wei County and Hanoi County to guard Mengjindu, and confronted Zhu Kun and Li Yi's Luoyang army across the river. At the beginning, Li Yi was determined to defend Luoyang, for example, he found out that Feng Yi's lieutenant was Liu Long, who had defected to Liu Xiu's side of the original regime, so he arrested Liu Long's wife, children, and children, both young and old, and killed them cleanly. But as the situation became more and more unfavorable for the new regime, Li Yi also began to look for a way back. At this time, Feng Yi wrote a letter to Li Yi. Feng Yi said in the letter: "I heard that the mirror is used to illuminate the form, and the past can be used to explain the truth of the present." In the past, Weizi left Yin Shang and entered Zhou, Xiang Bo rebelled against Chu and returned to Han, Zhou Bo welcomed the king and deposed the young emperor, and Huo Guangzun Xiaoxuan abolished Liu He, the king of Changyi. They are all afraid of heaven and fate, and they have seen the signs of survival and the fact of abandonment, so they can succeed for a while and have a great cause for eternity!If Chang'an can still help, postpone the years, be inseparable, and far from close, how can you Li Yi live alone in a corner?Now Chang'an is in chaos, the red eyebrows are close to the suburbs, the princes create disasters, the ministers have their own intentions, the law and discipline of the dynasty have been extinguished, the Quartet is falling apart, and different surnames are rising, so Guangwu does not avoid hardships and runs Hebei. Now the handsome people are gathered and the people are popular, although they are like the ancient fathers of the ancient fathers, it is not enough to compare. If you Li Yi can realize success or failure, determine the plan in time, and become a business like Weizi and Xiang Bo, and turn disasters into blessings, it is at this time. If you wait for the fierce generals to drive straight in, and the stern soldiers besiege the city, although they regret it, it will be too late. After Li Yi received the letter, he was very conflicted, he knew that the regime had come to an end, but because he betrayed the Liu brothers and was one of the masterminds of killing Liu Xuan, he was afraid that Liu Xiu would not forgive him, so he did not dare to surrender. After thinking about it, Li Yi sent a letter back to Feng Yi, in which he said: "I was originally with King Xiao (Liu Xiu) to plot an uprising and aim to revive the Han dynasty. Now I have been ordered to guard Luoyang, and General Feng has guarded Mengjin, both of which occupy the pass of the Central Plains, this is a once-in-a-lifetime opportunity!I am willing to work with General Feng, as long as we are of one heart and one mind, and we are well planned, we will be invincible. Please tell King Xiao of my plan, I am willing to do my best to help the country and the people. Since Li Yi contacted Feng Yi, he never sent troops to fight against Feng Yi. The urgent documents in various places were all pressed, ignored, and the army of 300,000 was in Luoyang, and not a single pawn was sent to help all places. After Feng Yi freed up his troops, he successively attacked the city in the north and south of the Yellow River, recruited more than 100,000 defenders, and then surrounded Wu Bo, the Henan Taishou of the Imperial Court, in Shixiang County, and Wu Bo sent people to quickly ask Li Yi in Luoyang for help. And Li Yi closed the door and ignored it. In the end, Li Yi sat back and watched Wu Bo's army be completely wiped out by Feng Yi. Moreover, Wu Bo himself was also killed by Feng Yi. Died in LuoyangFeng Yi saw that Li Yi kept his promise, and he did have the intention of surrendering, so he hurriedly sent someone to fly thousands of miles to deliver the letter and report the details of the battle situation to Liu Xiuyu. After Liu Xiu learned about this, he was not ready to accept Li Yi's surrender, but wanted to deliberately leak Li Yi's letter to let Zhu Kun know and use Zhu Kun's knife to avenge his eldest brother Liu Jiu. So, he immediately gave Feng Yi an order: "Li Jiwen is treacherous, and ordinary people can't get the gist of his words." We should make his letter public and tell the guards and captains in various places for security. Feng Yi didn't dare to disobey, so he had to do it. He made Li Yi's letter to himself into an official document, announcing to all places: This is a letter from King Wuyin, he is willing to submit to King Xiao on the surface, but in fact he has ill intentions, please be careful!Suddenly, Li Yi's secret letter to Feng Yi became an open letter, which was widely circulated in the north and south of the Yellow River. When Zhu Kun learned of this, he was very angry and immediately sent someone to stab Li Yi to death. 
Li Yi's storyThe word "machine shaft" comes from the "Later Han Shu Feng Yi Biography", in Li Yi's reply to Feng Yi there is such a sentence: "Today Yi guards Luoyang, the general town of Mengjin, according to the machine shaft, a thousand years, thinking into gold." Li Xian's note: "Machine, crossbow teeth also;."Axles, axles also. All of them are in the essence of things, so they are metaphorical. The machine axis is now mostly used as a metaphor for key and important places, positions, departments, and locations.
