The Prince of Beiliang Wu Jingtian led one hundred thousand Zhenbei troops to awe Mobei, but in a meticulously planned conspiracy, he was framed and killed at Mangshan. The Prince and Princess of Beiliang died tragically, one hundred thousand loyal souls suffered grievances, and the princely estate bore the charge of treason. Three years later, the only surviving heir Wu Hanye disguised himself as a beggar, carrying the Peach Blossom Sword and twelve shadow guards secretly lurking to return to the capital. The emperor claimed he would protect him for a lifetime of safety, but in reality, he coveted Beiliang's fortune, and various factions also surrounded and killed him. Wu Hanye took advantage of the situation, seized the Singing Dragon Spear, beheaded proud talents, gathered old subordinates, investigated the bloody case, and under the guise of challenging the five continents' sects, step by step closed in on the truth of that year.
