Zhinu, the son of Zheng Kuaiduo, the imperial eunuch of the Great Yong Kingdom, was suddenly killed when he was young. The blood feud made him grow up overnight. After ten years of hibernation, he returned to the capital under the pseudonym "Zanghai". With his astonishingly talented creative skills and insight into people's minds, he made his way step by step in the turbulent court. When he finally made the conspiracy to exterminate the family known to the world, killing his enemies and redressing the injustice, he also saw through the evils in the court amid the struggle for power. At that time, war broke out on the border, and at the time of internal and external troubles, Zanghai gave up his obsession with personal hatred, thought about the common people, and relied on wisdom to deal with all forces to help Dayong resolve the war crisis. From an avenger to a country-pacifier, he understood in the baptism of blood and fire that the true righteousness is to stabilize the country and make the people live in peace, rather than to indulge in the abyss of hatred.
