薛仁貴
When Yuchi Gong was fighting against Goryeo Koreans in later years (see Qin Shubao's section), he noticed the talent of a young warrior called Xue Rengui (薛仁贵, or Xue Li 薛礼). He pointed Xue Rengui as his adopted son because he believe Xue Rengui would be a decant squad in Tang Dynast's military. However, Xue Rengui was envied by Zhang Shigui (张士贵) and Li Daozong (李道宗). Zhang and Li tried to frame Xue Rengui. Xue Rengui was sent to jail after being set up by Zhang and Li. To save Xue Rengui, Yuchi Gong had conflicts with Li Daozong, and then, the emperor Li Shimin who believed in Li Daozong rather than Xue Rengui. After the judge announced that Xue Rengui would be sent to the death row, Yuchi Gong was so disappointed and angry. He hit the Zhijin Gate with his Bian to show his discontentment. He hit the gate so hard that his Bian broke into several pieces. He suddenly realized his teacher's words as well as what he did to Li Shimin in Meiliang-Chuan. He knew his time came, so he committed suicide in front of the Zhijin Gate. Li Shimin was very sad after knowing the death of Yuchi Jinde, so he put off the time to execute Xue Rengui and re-try the case. Later, Xue Rengui was proved to be innocent. Xue Rengui really became the best general in Tang Dynasty after several years. He defeated Turks, Tuyuhun, Tibetan Empire, Uighur Kingdoms, some city states and tribes along the Silk Road, and Korean Kingdoms in following years. Yuchi Gong's three sons, Yuchi Baolin (尉迟宝林, real in the history), Yuchi Baoqing (尉迟宝庆, fictional)and Yuchi Haohuai (尉迟号怀, fictional), were all great warriors in the next generation.
