The Three Kingdoms period has always been a familiar era, but most of them are concentrated in the late Eastern Han Dynasty and the pre- and middle periods of the Three Kingdoms period. Especially after the fall of the Shu Han Dynasty, many people may have little interest in the Three Kingdoms period. However, the low fame does not mean that the characters are not prosperous, the following small editor will introduce a famous general of Eastern Wu - Wu Yan. Wu Yan was promoted by Lu Kang; he participated in the "Battle of Xiling"; he was aware of the vision when the Western Jin Dynasty was preparing to attack Eastern Wu, and asked for help from Sun Hao, the lord of Eastern Wu, but was not allowed to witness the demise of Eastern Wu.

Wu Yan is a native of Wu County, Wu County, and there have been many Jiangdong Hao clans in this place, but Wu Yan is not, just a cold disciple. However, Wu Yan himself is very controversial, "eight feet long, hand beast", with this ability to become a county official. At that time, there was a protracted rebellion in Jiaozhou, which was controlled by Eastern Wu, and Wu led an army to quell the rebellion with Xue Jue, Tao Huang and others. Wu Yan was very envious when he saw Xue Jue's military appearance. One of liu zaxiangshi said to Wu Yan: "Looking at your face, you can become a general in the future, and you don't need to envy Xue Jue." "
Later, Wu Yan became a low-ranking officer and served under Sima Lu of Eastern Wu. Lu Kang is the son of Lu Xun, both father and son can be said to be famous generals of Eastern Wu, and Lu Kang is also regarded by many as the last famous generals of Eastern Wu. Lu Kang attached great importance to Wu Yan, believing that Wu Yan had general talent and courage. However, after all, Wu Yan was born in a cold door, and he had no military merits, and promoting Wu Yan in a hurry may cause dissatisfaction among other generals. Similar situations have not happened, such as Liu Bei's promotion of Huang Zhong, which made Guan Yu feel unhappy.
In order to reuse Wu Yan, Lu Kang came up with a plan. Lu Kang and various generals feasted, secretly ordering a person to pretend to be crazy and draw his sword and jump. The other generals sat up and ran away in fright, after which Wu Yan did not panic, but instead raised the case to make a defensive gesture. Lu Kang used this method to help Wu Yan establish his authority in the army. In the "Battle of Xiling", Wu Yan also showed some performance, and was ordered by Lu Kang to besiege Xiling. It is worth mentioning that the "Battle of Xiling" was shortly after Xue Jue and Tao Huang quelled the Jiaozhou rebellion.
Wu Yan moved slightly to Jianping Taishou, a position that was one of the front lines of Eastern Wu and Western Jin. At this time, although the Western Jin Dynasty lost Jiaozhou, it still showed a momentum of clamping down on Eastern Wu, and from Yizhou, Jingzhou, and Yangzhou could threaten Eastern Wu. The national strength of the two sides is not the same, Eastern Wu is not only limited in land, population, and economy, far behind the vast Western Jin Dynasty; its ruler Sun Hao is also an uncompromising emperor, which led to the fluctuation of the people's hearts and the weakening of the national strength of Eastern Wu during his reign. Wu's plan was put on the agenda by the Western Jin Dynasty monarchs.
The Western Jin Dynasty controlled Yizhou and had the advantage of taking the waterway down the river from Yizhou. Originally, after Deng Ai eliminated Shu Han, he proposed a plan with Sima Zhao to destroy Wu. At this time, the Western Jin Dynasty's Yizhou Assassin Shi Wang Mao was building warships in Yizhou. The wood for the shipbuilding flows east along the Yangtze River and is discovered by Wu Yan. Wu Yan quickly took the wood and reported to Sun Hao for reinforcements.
This is a bit like the original Shu Han, the general Jiang Wei discovered zhong hui's movements in Guanzhong and realized that Cao Wei was about to cut down Shu, but Liu Chan listened to Huang Hao and would not increase his troops. Sun Hao did not take Wu Yan's words seriously and did not give reinforcements to Jianping County. Wu Yan could only use iron locks to cut off the waterway of the Yangtze River, trying to block the eastward descent of the Yizhou water army in this way.
Of course, the iron lock could not hinder the footsteps of the Western Jin army. Wang Mao made a torch more than ten meters high and melted the iron lock as much as possible. Along the way, the Western Jin Dynasty army can be said to be overwhelming, and the various city passes on the Yangtze River defense line either fell in the wind or were conquered. Wu Yan held on to Jianping to resist the attack of the Western Jin army. However, Wu Yan's military strength was also very limited, and he could not stop the Western Jin Dynasty from destroying Wu. After the complete demise of Eastern Wu, Wu Yan surrendered to the Western Jin Dynasty.
After surrendering to the Western Jin Dynasty, Wu Yan was still willing to defend the honor of the Later Lord Sun Hao, attributing the destruction of Wu in the Western Jin Dynasty to Tianshi rather than personnel. Sima Yan, the Emperor of Jinwu, not only did not complain, but also appreciated Wu Yan's attitude. Wu Yan served successively in the Western Jin Dynasty as Jincheng Taishou, Dunhuang Taishou, Yanmen Taishou, shunyang Neishi (equivalent to Taishou), and after the death of Jiaozhou Assassin Tao Huang, he served as the governor of Nanzhong and the History of Jiaozhou, which is also in line with Liu Za's prophecy.
