- Description from novelbuddy

Introduction One:When Jiang Shouzhong finally resolved to help his wife vanquish demons and uphold the righteous path of the human world, he saw nothing but piles of white bones. Standing atop the battlefield of Asuras, the demoness was none other than his former wife.——Introduction Two:Above the temple halls, beneath the rivers and lakes, where the world of humans and demons divide, along the righteous and evil paths, countless charismatic individuals weave lives full of fireworks, unable to exhaust the tales of snow, moon, wind, and flowers.Kings and generals, peddlers and pawnbrokers, scholars and swordsmen, fiends and phantoms, they are all but pages in a book—each of varying thickness, some with twists and turns, others dull and ordinary, filled with ups and downs, joy and sorrow, or a mix of good and evil, with causes and effects unending.And the book of Jiang Shouzhong's life is undoubtedly the most captivating of all.——

"When will people understand.... I'm only half insane?"
