Murong Sheng (373----401), courtesy name Daoyun, was the eldest son of Murong Bao, emperor of Later Yan, and the fifth emperor of Later Yan during the Five Hu and Sixteen Kingdoms periods, reigning for 3 years. As a teenager, he was calm and intelligent, and he was full of strategy. When Jian Jian killed Murong Shi, he absconded to Murong Chong.
In the eleventh year of Jianxing (396), Murong Chui died, and his father Murong Bao took the throne. When Murong Bao marched south from Longcheng, Murong Sheng remained there to manage the rear. When Duan Subone rebelled, Murong Sheng quickly went out to meet the defense. Murong Bao was almost captured by Duan Suoku, and was able to escape with Murong Sheng. Murong Sheng repeatedly offered Murong Bao strange advice, but Murong Bao did not listen, so he repeatedly failed. After Murong Bao arrived at Longcheng, Murong Sheng stayed in the rear.
In the third year of Yongkang (398), Murong Bao was killed by Lan Khan, and Murong Sheng rushed to mourn, but the general Zhang Zhen strongly discouraged him, believing that he could not go. Murong Sheng said, "I am now laying down my life to tell him about my sadness and distress. Lan Khan was stupid and shallow by nature, and he would definitely take care of the affection of his family and could not bear to kill me. A few months is enough to stretch my ambitions. So he entered the Dragon City to mourn. Lan Khan's wife Yi Shi received Murong Sheng with tears in her eyes, and Lan Khan also loved him, sent his son Lan Mu to greet Murong Sheng, placed him in the palace, and appointed him as a servant and Zuo Guanglu, and respected him as he had done in the beginning.
Lan Khan's brother Lan Ti and younger brother Lan Nan persuaded Lan Khan to kill Murong Sheng, but Lan Khan did not agree. Murong Qi was the grandson of Lan Khan, and Lan Khan also spared him. Murong Qi went in to see Murong Sheng and planned together. Murong Sheng sent Murong Qi to raise an army outside the city, and the army reached thousands. Lan Khan sent Lan Ti to attack Murong Qi. Lan Ti was arrogant and absurd, and it was rude to serve Lan Khan, so Murong Sheng told Lan Khan that he was alienated from them, "Murong Qi is a child, and if he can't do such a thing, he must have someone in the city who will receive him." Ranti had always been arrogant and could not hand over the large troops to him. Lan Khan became angry and arrested Lan Ti and killed him, and lan Khan's brothers saw that Lan Ti was killed, and there was no one who was not worried or afraid, and they all rebelled against Lan Khan and defeated The army of Qiu Nimu.
Lan Mu said to Lan Khan, "Murong Sheng and we are enemies, Murong Qi is now rebelling, and Murong Sheng will definitely take him." Coupled with brotherly killing, it is not appropriate to develop a serious problem. When Lan Khan was about to kill Murong Sheng, he introduced and observed him. Murong Sheng's wife told Murong Sheng about this, so she pretended to be seriously ill and would no longer come and go, and Lan Khan gave up. Li Qian, Wei Shuang, Liu Zhi, Zhang Hao, and Zhang Zhen were all murong Sheng's former close friends, and Lan Mu used them as his confidants. Li Yan and the others went to see Murong Sheng several times and secretly agreed on a grand plan. Just when Lan Mu attacked Lan Nan and the others, killed them, and feasted on the soldiers, Lan Khan and Lan Mu were drunk. Murong Sheng took advantage of the toilet at night, crossed the wall with his naked body, entered the Eastern Palace, and killed Lan Mu with Li Yan and others. Go inside and attack Lan Khan and kill him. Lan Khan's two sons, Lu Gonglanhe and Chen Gonglan Yang, were stationed at Lingzhi and Baiwolf respectively, and Murong Sheng sent Li Qian and Zhang Zhen to attack and kill them. Inside and outside the Dragon City, both men and women are pleasant. Murong Sheng was humble but not proud, and did not call himself emperor. In that year, he exercised the power of the emperor as the King of Changle, and the domestic amnesty was changed to Jianping. The titles of the kings were demoted to dukes, and the civil and military officials were restored to their original positions.
After ascending the throne, Murong Sheng used harsh methods to control his subordinates, arrogant and unkind, and had a lot of suspicion of his subordinates. Because his wife Lan Shi was lan khan's daughter, he did not even remember her credit for saving him several times, and ordered her to be killed. After the strong persuasion of the patriarch, he was spared death, but he was not made empress. Murong Qi was also killed by him. Everyone in the group was cold and rebellious.
In the third year of Changle (401), Murong Sheng rebelled against Kumoxi, capturing many people and returning with property. The left general Murong Guo and the dianzhong generals Qin You, Duan Zan, and others planned to lead the forbidden army to attack Murong Sheng, but the matter was discovered, and Murong Sheng killed them, killing more than 500 people. The former general Duan Jie, the Marquis of Siqi, Qin Xing, the son of Qin You, and Duan Tai, the son of Duan Zan, took advantage of the people's hearts to shake and shouted loudly in the palace at night. Murong Sheng heard of the change and led his left and right cronies into battle, and everyone was defeated. Suddenly, a thief wounded Murong Sheng from the shadows, so Murong Sheng took advantage of the front hall, reprimanded the guards, and summoned his uncle Murong Xi, the Duke of Hejian, to explain the aftermath. Before Murong Xi could arrive, Murong Sheng died at the age of twenty-nine. Emperor Zhaowu and Emperor Zhongzong were buried in Xingping Mausoleum.
