Is “Nangong Shi, the grand general of Xiqi, was brave and skilled in battle, and made great contributions to King Wen of Zhou's recruitment of talents.” true?

Unlike the many fictitious characters of supernatural abilities in "Investiture of the Gods," Nangong Kuo (also written as Nangong Kua in some historical records) was a real founding minister of the Western Zhou dynasty. According to the "Records of the Grand Historian, Annals of Zhou, Part One": "命南宫括散鹿台之财，发钜桥之粟，以振贫弱萌隶。" He, along with San Yisheng, Hong Yao, and others, were trusted senior ministers of King Wen of Zhou, Ji Chang. They participated in the rescue of King Wen when he was imprisoned at Youli and assisted King Wu in conquering the Shang. The novel retains his identity as a mortal military officer, and although it adds exaggerated plots such as dueling with immortals, the historical background of his support for the Zhou royal house is entirely true.
