After Lin Ze remembered it, the world was like the bluestone slabs of the deep mountain gym and the fists and feet of Master Chen. He and his sister were adopted by Master Chen. There were twenty capable people in the gym, but Master Chen taught him internal and external skills alone, saying, "You are a brother, you have to protect your sister and support your brother." Here, he met Niu Ben, the "bison" who could carry boulders and charge, and Hua Yingxiong (nicknamed Military Advisor), who had endless plans. His sister guarded the stove and warmed the stomachs of the three of them with food.
After they grew up, Master Chen asked them to go down the mountain to practice, and Lin Ze took the three of them to set up a stall in the town. Before he could gain a foothold, the underworld came to provoke him. In order to protect his sister and brother, Lin Ze showed for the first time the inner strength he had learned in the mountains. Niu Ben carried a stone block half a man tall on the roadside to scare everyone, while the military advisor secretly calculated the opponent's retreat and quietly reported the news to distract the patrol. This unexpected conflict forced Lin Ze to step into the world of martial arts. From then on, he used his fists and feet as shields and his brothers as blades, leading the three of them to explore a way out step by step in the swamp of the underworld.
