Boston, USA, deep autumn, ten years ago. On a cold night in late autumn, even the most prosperous cities have their darkest side. Just like the beautiful Boston, a power struggle was taking place in its remote suburbs! The cold wind blew across the faces of two young men, both around seventeen or eighteen years old. One had an extremely stern expression, while the other exuded a wild and unruly demeanor. Both with towering physiques, their black clothes couldn't conceal their bleeding wounds. However, a fierce glint flashed in their eyes. "How are your injuries, Shaotang?" One of the young men asked in a deep voice filled with a chilling intent, yet it carried a strong sense of friendship towards the other man. This young man who spoke was Leng Tianyu, and the one with him was his close friend Ling Shaotang. They were sent to Italy since they were young to receive special training from the highest level of the mafia organization.
