With the thousand-year secret of the "Taotie Seal" as the core, the fate of the four families of Xu, Cai, Sun and Su is entangled. Xu Shiyun, the third son of the Xu family, unexpectedly discovers the mystery of his life experience - he is actually Zhao Chenyuan, the last prince of the Beishuo Dynasty. The "golden elephant and phoenix pattern" guarded by his family for generations, the Cai family's "soul-calming jade" and the Su family's "basalt armor" together form the key to sealing the ancient ferocious beast Taotie. As the conspiracy between the Blood Lotus Sect and the powerful official Li Xiang emerges, the four major families move from a power game to an alliance. In the process of uncovering their life experiences, emotional choices, and rivers and lakes disputes, they jointly fight against the ultimate crisis of "unblocking gluttony and subverting the world."
Lin Yueniang, the saint of the Blood Lotus Sect, awakens the remnant soul of the Taotie for revenge. Li Xiang uses his identity as an "orphan of the former dynasty" to instigate the war for the restoration of the country. The four major families need to work together to solve the triple dilemma of "rumor confusion", "power hunting" and "bloodline curse". Xu Shiyun struggled between the "mission to restore the country" and "protection of the common people". Cai Mengyuan awakened from the emotions of Su Wenjin (childhood sweetheart) and Xu Shiyun (life and death confidants). Sun Wenxuan challenged the feudal shackles of "women have no talent" with "New Interpretation of Women's Commandments", showing the growth and perseverance of individuals in the torrent of the times.
Taking "power and protection" and "revenge and reconciliation" as the dual axes, through the intertwining of the rise and fall of the four major families and the fate of individuals, it interprets the value of "the most delicious thing in the world is the common people". From the intrigues in the court to the chivalry in the world, from the blood curse to the emotional redemption, and finally the ending of "four races marrying to rule the world", it proves that "protecting rather than possessing" is the true meaning of civilization inheritance, showing the brilliance of humanity and the value of peace in troubled times.
