Xie Yuan, a low-level casual cultivator who was sentenced to "mortal bones" by his sect, struggled to survive amidst the ridicule and suppression of his senior brother Pei Yuheng. Everyone said that it was a foolish dream for a mortal to become an immortal, but he insisted on resisting the ninth heavenly tribulation with his body. When the thunder calamity tore apart the spiritual treasures and shattered the mountain-protecting formation, Xie Yuan was covered in blood but still standing, while Pei Yuheng's proud glazed Taoist bones burst into pieces in the thunder - at that moment, his Taoist heart collapsed.
