The Era of Immortality: My Secret Ally Is a Transmigrator

Lin Wei and Yun Zhao, two modern souls, unexpectedly transmigrate to the ancient Great Yin dynasty, where they discover that they are bound up in the mystery of immortality. Faced with the disorientation of being displaced in time and the potential dangers of eternal life, they decide to stay behind the scenes and hide in the mist-shrouded Valley of Biluoshan. Drawing on knowledge and wisdom far ahead of their time, they quietly kindle the spark of civilization: improving farm tools, spreading medical knowledge, and awakening new ideas. They train a loyal corps known as the Hidden Star Guards, support gifted craftsmen, and outmaneuver wise scholars, gradually guiding the ancient dynasty toward a quiet transformation into a modern civilization. But turning the wheels of history is bound to stir up hidden currents. The secret of immortality attracts prying eyes, waves of change meet resistance, and ancient taboos seem to awaken as well... When an eerie star that does not belong to this era glimmers in the night sky, Lin Wei and Yun Zhao realize that they have opened more than the shackles of an age. Eyes in the shadows have already turned toward them, and the truth of the world is far beyond anything they imagined. This long journey, which began in seclusion, will ultimately lead to the astonishing mysteries at the end of time and space. Can they protect each other, uncover the source of immortality, and face the "door" to the unknown?
