The king of Chu sent out his troops and helped Ba Manzi defeat the rebels and Shu army. After that, the king of Chu sent out an envoy to Ba to take over three towns. Ba Manzi told the Chu envoy that, as a general, he could not cede those three towns to another kingdom, but he was willing to compensate for his promises with his life. He then committed suicide by slitting his throat.晉•常璩《華陽國志》：周之季世，巴國有亂。將軍蔓子請師于楚，許以三城。楚王救巴，巴國既甯，楚使請城。蔓子曰：“籍楚之靈，克弭禍難，誠許楚王城，將吾頭往謝之，城不可得也！”乃自刎，以頭授楚使。楚王歎曰：“使吾得臣若蔓子，用城何為！”乃以上卿之禮葬其頭。巴國葬其身亦以上卿禮。
