"Four Tigers of Yuncheng: Yi Bo Yuntian" tells the story of four low-level teenagers in Yuncheng of the Dragon Kingdom - the calm and ruthless Daji, the smart and decisive Axu, the thoughtful Xiaoshuai, and the impulsive and passionate Yangzai. They struggled to survive in a scrapyard bullied by local snakes, to a mafia legend who fought for their lives to carve out a world.
A prison sentence for taking the blame for his brother became a turning point in fate. Daji lurked behind bars, and amidst the strife of power, he came under the legendary black master's door. Not only did he learn deadly martial arts, but he also understood the way of "hiding the edge"; outside the high wall, Axu learned layout, Xiaoshuai practiced intelligence, and Yangzi studied technology. Under the guidance of strange people in the market, the three of them transformed rapidly and secretly weaved a web of counterattack.
From the fire that merged with Brother Xibao in the city to stirring up the underground order in Yuncheng, they used brotherhood as their blades and their trust in life and death as their armor to tear apart class barriers in the light of swords and shadows. But the road to the top is never easy - the mentor in prison hides a fatal flaw, and the outside guides have their own agendas. The former brothers may face a choice of trust, and what they are fighting is not only a gang, but also the intricate shadow of power.
When friendship collides with calculation, when sharpness encounters a hidden arrow, can the four young men who crawled out of the swamp keep their original intention of "loyalty overshadowing the sky" and truly stand on the top of Cloud City? This is a river and lake epic about passion and betrayal, growth and cost. It depicts the lonely bravery of small people at the bottom who warm each other in the dark and fight against fate with their flesh and blood.
