生平

因其父朱然為將軍而被任免為官吏，後拜為建忠都尉。其叔父（論血緣應為表叔）朱才病逝，朱績承襲領有其兵，隨太常潘濬討伐五溪，以膽量、能力為人稱道。遷為偏將軍營下督，領治理盜賊之事，執法不偏不倚。魯王孫霸注意到朱績，時常到朱績的官署坐著，想與他結交為友，但朱績卻會立即下地而立，推辭不受。

249年，朱然病逝，朱績承襲家業和當陽侯爵，拜為平魏將軍，樂鄉督。明年，曹魏將領王昶率軍攻打江陵，不克而撤退。朱績與奮威將軍諸葛融書信道：「昶遠來疲睏，馬無所食，力屈而走，此天助也。今追之力少，可引兵相繼，吾欲破之於前，足下乘之於後，豈一人之功哉，宜同斷金之義。（王昶遠道而來感到疲睏，馬無糧可食，沒有辦法而撤走，此實在是天助我們。現今追弱少的他們，可率兵追殺，我想在前攻破他們，你可在後乘勢追擊，豈會是一人之功呢，宜一起有斷金之義。）」諸葛融答應朱績。朱績率兵追殺王昶至紀南，此地離城三十里，朱績先到與敵戰得勝，諸葛融卻沒有推進，朱績最後也因而失利，被王昶用計大敗，鐘離茂、許旻被斬。

孫權對朱績大為嘉許，責怒諸葛融，諸葛融之兄大將軍諸葛恪身為貴冑，所以諸葛融得而不被廢棄。起初，朱績與諸葛恪、諸葛融已不太喜歡對方，直至今次事件，仇怨更深。252年，朱績遷為鎮東將軍。翌年春，諸葛恪進攻新城，要求朱績一起合力，但卻要他留置半州，命諸葛融兼領其任。冬天，諸葛恪、諸葛融被殺害，朱績遂回到樂鄉，被授假節。五鳳年間（254-256），朱績改回父親朱然本姓，名為施績。257年，拜為驃騎將軍。

後孫綝執掌朝政，大臣們互相差疑，施績怕東吳會有擾亂，而曹魏又會乘機挑釁，便秘密書予蜀漢結交，講述為怕被併吞的憂慮。蜀便派右將軍閻宇率五千兵到白帝城防守，等待施績的消息。太平二年（257年），魏徵東大將軍諸葛誕在壽春叛亂，並向東吳求援，魏驃騎將軍王昶領兵據守夾石，對江陵施加壓力，令當地守將施績和全熙等不能抽身到壽春支援諸葛誕。永安初年，遷為上大將軍、都護督，由巴丘北上至西陵。元興元年（264年），拜為左大司馬右軍師，建衡二年（270年）四月逝世。

評價

三國志評曰：「朱治、呂範以舊臣任用，朱然、朱桓以勇烈著聞，呂據、朱異、施績咸有將領之才，克紹堂構。若範、桓之越隘，得以吉終，至於據、異無此之尤而反罹殃者，所遇之時殊也。」

Family background

Shi Ji was the son of Zhu Ran, a general who served under Wu's founding emperor Sun Quan. Zhu Ran's family name was actually Shi (施), but he changed his family name to Zhu (朱) as he was adopted by his maternal uncle Zhu Zhi. Shi Ji initially took on the family name of Zhu, but sometime between 254 and 256 he received permission from the second Wu emperor Sun Liang to change his family name to Shi.

Service under Sun Quan

With help from his father, Shi Ji started his career as a Gentleman (郎) serving the Wu imperial palace. Later, as he grew older, he was commissioned as a commandant under the title "Commandant Who Establishes Loyalty" (建忠都尉). After his uncle Zhu Cai (朱才) died, Shi Ji was put in charge of the troops who used to be under Zhu Cai's command. In 231, he followed Pan Jun on a campaign against rebellious local tribes in Wuling Commandery (武陵郡; around present-day Changde, Hunan), and became famous for his courage and strength in battle. Shi Ji subsequently served as a supervising officer in charge of dealing with bandits and robbers, and was known for sternly upholding the law. Through his actions, Shi Ji attracted the attention of Sun Ba, the Prince of Lu, Sun Quan's fourth son. When Sun Ba visited Shi Ji in his office and offered to start a friendship with him, Shi Ji knew his place so he remained humble (e.g. remained standing when Sun Ba sat down) and politely declined.

Sometime in the 240s, a power struggle broke out between Sun Ba and his third brother Sun He, the Crown Prince, as the former wanted to seize the position of heir apparent from the latter. Two opposing factions also emerged from among Sun Quan's subjects: On one side, Shi Ji, along with Lu Xun, Zhuge Ke, Gu Tan, Zhu Ju, Teng Yin, Ding Mi (丁密) and Wu Can, believed that Sun He was the rightful heir apparent so they supported him. On the other side, Bu Zhi, Lü Dai, Quan Cong, Lü Ju, Sun Hong (孫弘), Quan Ji (全寄), Yang Zhu (楊笁), Wu An (吳安) and Sun Qi (孫奇) supported Sun Ba. The power struggle ended in 250 when Sun Quan deposed Sun He and replaced him with Sun Liang, and forced Sun Ba to commit suicide.

When his father Zhu Ran died in 249, Shi Ji inherited his father's peerage as the Marquis of Dangyang (當陽侯) and was subsequently promoted to General Who Pacifies Wei (平魏將軍) and appointed as the Area Commander of Le District (樂鄉; east of present-day Songzi, Hubei).

In 250, Wang Chang, a senior general from Wu's rival state Wei, led the Wei forces to attack the Wu-controlled Jiangling County (江陵縣; in present-day Jingzhou, Hubei). When Wang Chang was withdrawing his troops after failing to breach Jiangling County's walls, Shi Ji wrote to the Wu general Zhuge Rong: "(Wang) Chang has come a long way; he and his men are weary and their horses have no more fodder. Heaven is on our side. I don't have enough men to attack them so I hope you can lead your troops to support me. I will attack them from the front while you can mop them up from the rear. The glory won't be only mine; this is an opportunity for us to work together." After Zhuge Rong promised to help him, Shi Ji then led his troops to attack Wang Chang and his men at Jinan (紀南), which was located about 30 li away from Jiangling County. Although Shi Ji initially had the upper hand, he ultimately lost the battle when Zhuge Rong broke his promise and did not show up to help him. After the battle, the Wu emperor Sun Quan praised Shi Ji, but severely reprimanded Zhuge Rong and wanted to relieve him of his appointment. However, he eventually pardoned Zhuge Rong as he had to "give face" to Zhuge Rong's brother Zhuge Ke, whom he favoured and heavily relied on. As Shi Ji was initially already not on good terms with Zhuge Ke and Zhuge Rong, this incident further deepened the rift between him and the Zhuge brothers.

Service under Sun Liang

After Sun Quan died in 252, his youngest son Sun Liang became the next Wu emperor, with Zhuge Ke serving as regent. In the same year, Sun Liang appointed Shi Ji as General Who Guards the East (鎮東將軍).

In the spring of 253, when Zhuge Ke was away leading Wu forces to attack the Wei fortress of Xincheng at Hefei, he requested support from Shi Ji's units but did not bring Shi Ji along and instead ordered him to remain at Banzhou (半州). He then granted his brother Zhuge Rong acting imperial authority and ordered him to take command of Shi Ji's units and lead them towards the Mian River to attack Wei reinforcements coming from the west to reinforce Xincheng.

In the winter of 253, Sun Jun, a distant cousin of Sun Quan, overthrew and assassinated Zhuge Ke in a coup d'état. He then ordered Shi Kuan (施寬), Shi Ji, Sun Yi (孫壹) and Quan Xi (全熈) to lead their troops to Gong'an County to arrest Zhuge Rong. Zhuge Rong ultimately committed suicide while his three sons and Zhuge Ke's extended family were rounded up and executed. After the coup d'état, Sun Jun became the new regent and he granted acting imperial authority to Shi Ji and ordered him to revert to his previous appointment as the Area Commander of Le District (樂鄉; east of present-day Songzi, Hubei).

In 257, Shi Ji was promoted to General of Agile Cavalry (驃騎將軍), one of the top positions in the Wu military. In the previous year, following Sun Jun's death, his cousin Sun Chen succeeded him as the regent of Wu. When Sun Chen was in power, he caused fear and panic among the Wu officials when he started purging his political opponents. Shi Ji worried that Sun Chen's actions would lead to a civil war in Wu, and feared that Wu's rival state Wei would take advantage of the internal conflict to attack Wu. He then secretly contacted Wu's ally state Shu and requested their support. In response, the Shu government sent a general Yan Yu to lead 5,000 troops to stand by at Baidicheng near the Wu–Shu border and assist Shi Ji when necessary.

Service under Sun Xiu and Sun Hao

In 258, Sun Chen deposed the Wu emperor Sun Liang, whom he had a falling-out with, and replaced him with his brother Sun Xiu. Later that year, with assistance from the generals Zhang Bu and Ding Feng, Sun Xiu ousted Sun Chen from power and executed him. At the beginning of his short reign, Sun Xiu appointed Shi Ji as Upper General-in-Chief (上大將軍) and Protector-General Controller (都護督), and ordered him to relocate his headquarters from Baqiu (巴丘; present-day Yueyang, Hunan) to Xiling (西陵; present-day Yichang, Hubei).

Shi Ji continued serving under Sun Xiu's successor, Sun Hao, after Sun Xiu died in 264. In the same year, Sun Hao appointed Shi Ji as Left Grand Marshal (左大司馬). Shi Ji died in 270.

The Zhen'gao recorded that Shi Ji had a daughter, Shi Shunü (施淑女).
