Sima Shi (in Chinese: 司馬師), also known as Emperor Jing of Jin (in Chinese: 晉景帝), is a supporting protagonist in the 14th-century Chinese classic novel Romance of the Three Kingdoms by the late Luo Guanzhong, and its multiple adaptations. He is Sima Yi and Zhang Chunhua's eldest son and Sima Zhao's elder brother.
During the early years, Sima Shi is a smart and sensible child that was familiarly polite to his family so well. As a result of the time, Sima Shi has been helping his father Sima Yi to brought a many hope, only he is a one who expresses his loyalty and excellent technique by referring to his father's true implication. A few years later, Sima Yi was willing to mention that at these times to starting a coup and used a conspiracy method to immediately counter Cao Shuang, Sima Yi reportedly confided to Sima Shi's information. But thought that Sima Shi wants to keep it on and his younger brother Sima Zhao accepted the confession question directly with others (although Sima Guang found this project risky and that was of the opinion that Sima Yi had prepared the coup with Sima Shi and Sima Zhao). In addition, Sima Shi intends to sent out a group of more than 3,000 men to find Cao Shuang and his supporters to settle accounts.
When Sima Yi began to realize his plans, Sima Yi's incredible strategy is very agile and amazing in this quality, Sima Shi is managed to recruited several men to defeated the coup. Even Sima Shi didn't know anyone else at all, but he couldn't make that kind of shortcoming and was going to upset. Suddenly, Sima Yi quickly rushed away with his family for no reason, but Cao Shuang should have to make his own intrigues and defeated them. Once Sima Yi successfully to overthrow Cao Shuang and replaced him as Emperor Cao Fang's regent, he rewarded his son with the title of Marquess of Changpingxiang. Sima Shi then became his father's assistant, although there was no record of his accomplishments in those years. After Sima Yi dies, he recovered his father's post without significant opposition, after his father had earlier this year repressed a rebellion that had been missed by Wang Ling and slaughtered Wang's clans.
Sima Shi identify his expectations and pretended to be a shameless tactician, as well as the only one knew that this meaning was very despicable or ruthless, but also wanted to quickly prove his military reputation. After Sun Quan's death and was succeeded by his son Sun Liang, Sun Liang served as the new emperor of Wu empire. By now on, Sima Shi was preparing himself to lead the armies to opposed Wu and stand on their region, he also suggested defeated Zhuge Ke in campaign and exposing the whole opponent's impunity, Zhuge Ke was able to bring a critical blow to Sima Shi's forces. However, Sima Shi managed to stayed in power by humbly confessing his faults to the public and giving promotions to generals who had tried to stop his campaign. Sima Shi successfully defeated Zhuge Ke in a great battle, his reputation was established, while that of Zhuge Ke was shaken (because of Zhuge Ke's refusal to admit his fault), and Zhuge soon fell while the Sima power was asserting itself.
He did a brilliant action to consolidate his power, at the expense of Cao Fang. Cao Fang was fond of Minister Li Feng, Sima Shi suspected they were plotting together against him. By the way, Sima Shi summoned and interrogated Li Feng, when Li Feng refused to divulge his conversations with the Emperor. Sima Shi was defeated him to death with the handle of sword, then accused Li Feng and his friends Xiahou Xuan and Zhang Ji of treason, and had them and their families executed. Cao Fang also forced to divorce his wife, Empress Zhang. These actions further subjected the officers by terrorizing them. Cao Fang is very angry about the deaths of Li Feng and Zhang Ji, later, his associates presented him with a plan. When Sima Zhao arrives at the palace for an official visit before returning to his defense post in Chang'an, he is trying to kill Sima Zhao and seize his troops, and then use them to attack Sima Shi.
Cao Fang is fearful and paralyzed, and did not implement the plan, but the information had already been disclosed to Sima Shi. Sima Shi then forced Cao Fang to resign, he informed Cao Fang's stepmother, Empress Dowager Guo, that he intended to make Cao Pi's brother, Prince of Pengcheng, Cao Ju, Emperor, she succeeded to persuade him that this succession would not be appropriate; since Cao Ju was the uncle of her inept husband Cao Rui, such a succession would leave Cao Rui without an heir. Sima Shi was forced to agree with her, and he did, as she had suggested, emperor Cao Mao in his place. Despite this, Empress Guo's intentions and Cao Mao's intelligence, they had very little impact in stemming the rise of the Sima family. In response to Cao Fang's withdrawal, Wei commander Guanqiu Jian and Wen Qin raised a rebellion against Sima family, so sent their four sons to Wu as adults and pleased Sun Liang, does not receive strong support from Wu.
Guuanqiu Jian and Wen Qin crossed the Huai River and headed for the spring from Shouchun, there was no way to take advantage of Xuchang in Luoyang. When they arrived in Xiang County, Sima Shi monitored Guanqiu Jian and Wen Qin, he sent Zhuge Dan to lead many soldiers to attack Shouchun. At the time, Sima Shi sent Hu Zun to lead the soldiers of Qingzhou and Xuzhou, but cut off the road of Guanqiu Jian and Wen Qin from Xiang county to Shouchun. Sima Shi should himself led the main forces and gathered in Ruyang. Also, Sima Shi also called Deng Ai with more than 10,000 troops to Lejia county, tempting Guanqiu Jian and Wen Qin attacked. Guanqiu Jian really called Wen Qin to fight against Deng Ai. Sima Shi commanded the large cavalry and attacked Wen Qin from the back. Wen Qin was defeated. Sima Shi is absolutely unable to endure their answers and the most important thing is to determine his own wariness.
This revelation has long been understood, Sima Zhao has should willing to apologized with others. Sima Shi was appointed as an invincible minister of the chaos, constantly respond the harmonious and showed up to be a equal. Guanqiu Jian heard the news in Xiang County, hurriedly abandoned the city and left. Sima Shi does not want to force him to feel miserable, maybe it will be easier to continue this way. After Guanqiu Jian went to Shen county, he was shot dead by the people in the grass beside the river. Wen Qin and his family fled to Wu in one breath, the Guanqiu and Wen two families were staying in the Wei and being killed. He hoped that his uncle Sima Fu would take the helm. At the urgent request of Zhong Hui and Fu Gu, he led the troops himself, which greatly facilitated the victory against Guanqiu Jian.
But Wen Qin's elder son, Wen Yang's raids, Sima Shi, in his anguish, worsened the condition of his eye, which came out of its orbit, causing a serious degradation of his health. Less than a month after the end of rebellion, he is also died in Xuchang, but Sima Zhao waiting to succeed him.
