Huo Liaoyuan

Liaoyuan Huo is a member of the Handicapped Warriors. He is the leader of the group after Lao Da left the Sima clan. Because of his handicap and resilience, he is often in charge of suicidal missions to assassinate a powerful figure. His targets included Xu Lin, Dong Zhuo, and even Cao Cao.

When the Sima clan survived the extinction under Cao Cao's hands, Liaoyuan Huo was tasked to help a rival power to keep Cao Cao in check. From then on, Liaoyuan Huo takes on the "Zhao Yun" identity permanently.
