李道宗
Yuchi Gong was the person in Shuo Tang whose stories were closest to the real history. Although there was no Three Bians versus Two Jians in real history (Qin Shubao never used Jian in real history, and Yuchi Gong never used Bian either. They both used spears in real history), the battle of Meiliang-Chuan was real. Stories of the battle of Luo Yang and the conflict between Li Brothers were also true stories in the history. Yuchi Gong also had conflicts with Li Daozong in later years, which was recorded in different historical books. However, the reason he argued and beat Li Daozong was not because of Xue Rengui. In reality, both Zhang Shigui and Li Daozong in real history were great and loyal generals who contributed a lot to Tang Dynasty. Their contributions were no less than Yuchi Gong's and Xue Rengui's. Xue Rengui's talent was actually discovered by Zhang Shigui. Of course, Yuchi Gong never committed suicide. When he was old, he retired from the government and became a devout Taoist priest. He lived a happy and easy life for 16 years before his death.
