This is a soulful epic that spans thousands of years and connects ancient and modern times. The story is inspired by the archaeological discovery of the tomb of the Northern King Helianzhuo. The two lines are intertwined. It tells the story of Lin Weixi, a modern cultural relic restorer, and Yan Beichen, an archaeologist, who gradually awaken and face each other's past lives as the Northern King Helianzhuo and the medical girl Lin Yanyu thousands of years ago. In the ancient line, it is the tragedy of a king who bears the hatred of his family and country and a medical woman who insists on benevolence in troubled times. Under the crushing power of intrigue, war and fate, they cannot love each other and are separated by life and death. In the modern line, it is a healing story of how two people with traumatic memories, relying on professionalism, rationality and inseparable affection, restored cultural relics step by step, clarified the historical truth, and finally repaired each other's inner wounds and chose to renew their relationship on the ruins. It is not only about a soul-stirring love, but also a reconciliation with history, self, and regret.
