In the last years of Xiqiang, the government declined. There are rumors in the world that "Nine Nether Mysterious Techniques can defeat all enemies", and the peerless secret book "Nine Nether Mysterious Techniques" suddenly appeared, causing a bloody storm. Xia Xingtian, the leader of the Xia Family, a martial arts family, was framed by the "Zijiao", a secret organization of the Western Qiang court, and suddenly encountered disaster because he was involved in the competition for "Nine Nether Mysterious Skills".

However, on this not-so-easy road to revenge, a shocking and unknown secret is gradually discovered... Family feud and national hatred are intertwined. When grievances are difficult to resolve, everyone makes completely different choices.
