As we mentioned earlier, Liu Yu quickly returned to the south because of problems in the south, causing the loss of the just-laid Guanzhong again. Liu Yu's Second Northern Expedition ended in this way, this episode we see, what is the reason that made Liu Yu return to Jiankang so desperately. Abandoning the Northern Expedition has achieved a great situation, and how did Liu Yu stage the Zen drama again and establish Liu Song.

Earlier we said that there was a reason for Liu Yu to go back, it was to follow Liu Yu for more than twenty years of important strategists, Liu Muzhi died, Liu Muzhi was able to think of things he did not expect for Liu Yu, it was Liu Yu's left arm and right arm, just like Liu Bang's Zhang Liang, Liu Yu personally went north, at this time Liu Yu completely controlled the power of the Eastern Jin Dynasty, Liu Muzhi guarded the capital for him, which was enough to show Liu Yu's trust and dependence on him.
The problem also lies in this, since Liu Yu trusts Liu Muzhi so much, Liu Muzhi should do things according to Liu Yu's ideas, after Liu Yu laid Luoyang, he made such a great merit, Liu Muzhi should manipulate the imperial court and let the imperial court reward Liu Yu, but Liu Muzhi did not do this, according to their relationship, Liu Muzhi must know that Liu Yu wants to further increase jiuxi.
Sure enough, because the imperial court (that is, Liu Muzhi) did not move, Liu Yu was not happy. I don't know whether Liu Muzhi deliberately did not give, or negligence, if Liu Muzhi deliberately did not give that Liu Muzhi may have a different heart, then the problem is serious. When he was leading the troops, Liu Muzhi sat in the capital, and if he had different intentions, Liu Yu's mirror was very dangerous.
Taking a step back, Liu Muzhi is not a different heart, in case he is like Xun Yu, in Cao Ying's heart in Han, Cao Cao supports Xun Yu of han to be loyal to you, but you are the King of Wei, then I do not agree. That would be trouble, so there can be no deviation in this period.
So Liu Yu sent people back to the imperial court to vent his dissatisfaction, did not directly look for Liu Muzhi, in fact, knocked Liu Muzhi, Liu Muzhi of course can also see, Liu Yu so knocked, Liu Muzhi panicked, this panic Liu Muzhi died of illness, Liu Yu did not expect Liu Muzhi so can not withstand the beating.
Even if Liu Muzhi was negligent, then together with Liu Muzhi, Xu Xianzhi, who guarded Jiankang, was also negligent? Xu Xianzhi was also Liu Yu's right-hand man, and he did not remember to reward Liu Yu. It's impossible for two people to be negligent at the same time, right? So Liu Yu couldn't sit still.
From the later development, it can be seen that Liu Muzhi and Xu Xianzhi are unlikely to betray Liu Yu, then they are subordinates of the powerful ministers, and they still have concerns about doing things, although Liu Yu has great power, but after all, he is not an emperor, doing some things for people's subjects, nominally legally unreasonable, so Liu Muzhi Xu Xianzhi mentioned that Liu Yu still has concerns about doing things.
In this way, Liu Yu desperately returned to the south and immediately became emperor on behalf of the Jin Dynasty, which can be understood, and only when he removes this layer of gauze, including his team, can he do things conveniently and naturally.
Now let's look at the process of Liu Yu's founding of the country and becoming emperor
Liu Yu's usurpation of the throne was carried out according to a proverb at that time, called "there are two emperors after Changming", Changming refers to Emperor Xiaowu, meaning that there were two emperors after Emperor Xiaowu of the Jin Dynasty.
Therefore, Liu Yu did not directly depose the emperor and replace him with himself, just like Huan Xuan mentioned earlier. Liu Yu first waited for Emperor An of Jin to die, and then asked his younger brother Sima Dewen to be emperor. In this way, there were two emperors after Emperor Xiaowu, and some people said that Emperor An of Jin was killed by Liu Yu. Because Liu Yu was more than fifty years old at that time, if natural death did not necessarily survive him, so he was killed.
This Sima Dewen is Emperor Gong of Jin, smarter than Emperor An, Emperor An is stupid, Emperor Gong of Jin knows how he came to power, and he also knows why Liu Yu let him ascend to the throne, so he is happy and happy every day, not thinking about what will happen in the future, and soon less than a year Liu Yu sent someone to tell him that it was time to step down. The emperor also accepted it very gracefully, and he and the people around him said that the Jin Room had long since died in name only, and I had no regrets today.
There have been two such Zen concessions in history. For a time, Cao Wei replaced the Eastern Han Dynasty, and the second time it was Sima Shi who replaced Cao Wei. Who the heavens spared, sima shi, who had won the country unjustly in those years, is also facing the usurpation of the throne by his vassals today. The previous two times were when Zen let the abdicated emperor on the stage hand over to the new emperor, but this time it was different. Emperor Gong of Jin did not attend the event, and after handing over his things, he returned to the Palace of Langya himself to devote himself to the Buddha and refused to participate.
Liu Yu could only hold the ceremony himself. The Sima family, which affected the world, finally stepped off the stage of history, and like Cao Wei and the Western Jin Dynasty in those years, they were already princes before the Zen throne, and Liu Yu was also named the King of Song, so the dynasty now established is called Liu Song.
Because it and the Qi Liang Chen established later were in the south, it was historically called the Southern Dynasty. Later, the Northern Song Dynasty fell, and the Song that Zhao Zhao continued was called the Southern Song Dynasty, so this Song could not be called the Southern Song Dynasty in history, but should be called Liu Song. Although Liu Yu was good to the people, he was cruel to the Eastern Jin dynasty, and a year later Emperor Gong of Jin was killed.
Here we get here, and in the next episode we talk about the same very chaotic Liu Song regime, to see how they are chicken feathers.
