The Strongest Servant in History

After transmigrating as a third-rank servant of the Su family, former special forces soldier Ding Erdan initially planned to live comfortably. However, using modern knowledge, he creates top-tier yellow and purple dyes, helping the Su family overcome crises and rise to become a first-rank servant. Navigating between young mistress Su Muyan, Wang Zhuqing, maid Yu'er, and hidden identity Princess Qin Lan, he repeatedly overcomes obstacles from the Bai family and other three major clans. He wins the imperial examination in the capital, helps establish the Jinyiwei to reform the court, and finally succeeds in returning to Jiangnan. Just as he prepares to leave, Su Muxue publicly confesses her love and vows to marry him.
