Everyone who comes to the city carries a beautiful wish in their heart. His wish was revenge. Once a young master admired by countless people, he lost everything in a single night. His family was murdered, and he was left penniless and adrift. He traded his lifespan to a merchant, who pointed him in a direction. Following that lead, he embarked on a path of revenge from which there was no return. Along the way, he witnessed love and hate, felt the warmth and coldness of the world. Some were lost in luxury, while others struggled to survive. Above the firmament and beneath the soil, love and hatred were the truth, while fate and reason were illusions. The countless facets of this world formed a dazzling panorama of mortal life, ensuring that his journey of revenge was no longer a lonely one. He never stopped along the way, always pressing forward. In the end, for the sake of revenge, he sold his very soul to the devil.
