In that vast black land known as Guanwai, the storm is raging, and a mafia legend is quietly beginning.
This is the Northeast, where white mountains and black waters breed simple and generous people, and also hide the turbulent underground world. Li Tianlong, a young man from an ordinary background, cherishes the longing for a better life, but under the influence of fate, step by step into the world of the underworld.
At first, Li Tianlong just wanted to protect himself and the people around him, dealing with evil forces in the streets. But as the situation changed, his name gradually spread among the underworld, attracting a group of like-minded brothers. With their extraordinary courage and wisdom, they have emerged in the underworld world outside the customs.
However, there is no shortage of opponents in this arena. Another underworld force, the Tiger Gang, was deeply threatened by the rise of Li Tianlong and others, and the conflict between the two sides continued to escalate. From the initial street fight to the subsequent battle for business turf, every confrontation was thrilling.
In this turbulent situation, Li Tianlong not only has to face enemies from outside, but also deals with conflicts and differences within the gang. The betrayal of his brothers and the conspiracy of his enemies put him in many difficulties. But he never gave up, relying on his firm belief and tenacious will to resolve crises time and time again.
In the changing situation outside the customs, Li Tianlong and his brothers struggled in the underworld world. Their story became a legend and was praised by future generations. "The Story of the Underworld" records not only their blood and passion, but also the changes, love, hatred, and hatred of the Northeastern underworld in that era.
