King Duosi

King Duosi is the fictional former governor of Tulong Cave. He served under King Meng Huo and was a very close friend to Meng You. King Duosi was very much well known amongst the Nanman as the "Sage of Nanman". Duosi assisted the very outnumbered Meng Huo through his spring water tactic that he used on Zhuge Liang, such as the Tulong's poisoned waters. This tactic ultimately resisted Zhuge Liang for quite some time. However, through the help of Meng Jie, Zhuge Liang defeated this strategy.
