Once-prosperous towns are now devastated, corpses litter the roads, and the people can barely survive. Prince Li Yuny i narrowly escapes death in the catastrophe. Seeing the people, once safe and prosperous, driven from their homes, he is overcome with grief and indignation. Determined to save the people, Li Yuny i resolves to step forward, but he knows he is too weak to face the rebels head-on. It would be like throwing an egg against a rock. So, drawing on his ingenuity and the common people's awe of and belief in the legend of the Night Wanderer, he assumes the identity of the mysterious “Night Wanderer’s Emissary.” He forms an army of Night Wanderers to fight the rebels and rein in the powerful, restoring the Great Liang Dynasty’s rule and giving the people a peaceful home. The land gradually comes back to life, too. Li Yuny i becomes a hero in the hearts of the people, and his story is passed from mouth to mouth until it becomes legend.
