Who wrote Fu Jian × Mu Rongchong Huang Qi?

Ran Yu's lyrics are great. Qi Huang is a song with the theme of "Fujian × Mu Rongchong" and Mu Rongchong as the narrative perspective. This song was sung by Chen Xing, with excellent lyrics and laid-back sauce. Mu Rongchong and Fu Jian in The Secret Order of the Phoenix Society are legendary figures in history. For Mu Rongchong, Fu Jian became the greatest hatred in his life. As a trophy, he was once favored by Fu Jian, but for the ambitious Prince Mu Rongchong, the man Fu Jian ruined his life.
