Crossing the White Mountains and Black Waters for a Hundred Years

A covenant between ancestors and grandchildren that spans hundreds of years, a family legend that ignites a glimmer of light in the dark ages. In 2026, while cleaning up his ancestral home, Li Siyuan, a master of science and engineering, accidentally touched an ancestral jade pendant and traveled back to Jilin in 1931. He witnessed with his own eyes that his family's "Jishengtang" drug store was in dire straits under the pressure of Japanese capital. His grandfather Li Yaozu, who was only 18 years old, was facing the desperate situation of his family being ruined. They used the small "Jishengtang" as a starting point, introduced business concepts that transcended the times, and reorganized the family business; they used traditional Chinese medicine as weapons to deal with Japanese pharmaceutical companies in invisible business wars. But in troubled times, peace is just an illusion. As the Japanese invaders pressed harder and harder, the grandfather and grandson gradually realized that just revitalizing the family was not enough. They began to use their ever-expanding business network to secretly support the anti-Japanese forces and build a secret resistance front in logistics, finance, intelligence and other fields. However, the shadow of the Kwantung Army's secret service followed closely, and internal betrayals, enemy traps, and tests of life and death followed one after another. From the counter of the drug store to the forest and snow fields of Changbai Mountain, from business games to secret battle lines, Li Siyuan and Li Yaozu walked on the edge of the knife every step of the way. In the temper of blood and fire, the grandfather grew from a young boy to a leader who supported one side; under the cruel baptism of history, the grandson transformed from an idealist with empty theories to a warrior who knew how to hide his sharp edge and combine knowledge with action. "A Hundred Years Across White Mountains and Black Waters" witnesses a rewritten family history and feels the passion and emotion that spans time and space.
