The Sovereign's Revenge

After Chancellor Tyrion Leigh killed the City Lord Lucas Feng, Lucian Feng used a forbidden sword technique for revenge, which left him mentally disabled. Because he resembled Lucas Feng, his fiancée, Rosalind Lynn, took care of Lucian for three years. Once he recovered, Lucian's memory and power returned. He intimidated The Four Great Families, shamed the Lynn Family, destroyed Ye Xiong and Zane Davenport, exposed the fake City Lord, and defeated Tyrion Leigh to protect Rosalind.
