A modern ordinary person {Chen Yan} accidentally traveled through the world of Water Margin, which coincided with the beginning of the gathering of righteousness in Liangshan. He saw the war in the troubled times, the people were displaced, and he also saw the chivalrous spirit and warm-heartedness of the world. He has no ability to reach heaven, but he only keeps his heart of fireworks in the world, warms the Liangshan brothers with gentle fireworks, and protects the mountains and rivers in all directions with his firm original intention. It does not violate chivalry, nor does it go against one's true heart. He weaves fireworks in the world in the Liangshan Mountains, and builds mountains and rivers in troubled times. He makes heroes feel warm when they return home, and makes the world peaceful in troubled times. In the bloody rivers and lakes of Water Margin, he walks a different path of fireworks guarding mountains and rivers.
