In the last years of the Sui Dynasty, Emperor Yang's three expeditions to Goguryeo and the construction of the Grand Canal exhausted the country's power. Refugees broke out all over the world, and vassal towns began to appear. Above the court, forces such as the Yuwen clan, the Li clan, and the Dugu clan are fighting openly and secretly; in the arena, due to the demise of all the top masters after the "Huashan Sword Discussion" decades ago, and the suppression of the imperial court's "martial ban", the martial arts sects withered, and the masters fell apart. The world jokingly called "the age of exhausted heroes". People in the arena all want to "restore the heroic soul", but most of them are trapped in self-interest and fighting.
