Amber Age

Lu Yin, a young graduate student, accidentally obtained a mysterious piece of amber containing a strange metal key in an inconspicuous antique shop seven years after his father disappeared. From then on, he was hunted by a powerful mysterious organization called "Shadow" and was forced to be involved in a grand mystery that spanned time and space. The warning left by his father, the amber insects that move on their own, the super-era transportation network hidden under the abandoned tunnels, the legendary Moon Shadow Gate on the Arctic ice sheet... The clues are intertwined, pointing to an ancient secret that can subvert the world's perception. Holding the "Amber Key" that can create a strange connection with it, Lu Yin formed an alliance with his father's former companions and dealt with underground forces that were both enemies and friends. He must solve the puzzle left by his father before the "Shadow" organization succeeds, and arrive at the location of the door in time for the "moon and shadow coincidence" that occurs once in seven years. This is a race against time and a battle of wits dancing with shadows. In this adventure that spans modern cities and lost civilizations, Lu Yin gradually discovers that his father's disappearance, the truth about the key, and even the ultimate goal of the "Shadow" organization are far more shocking than he imagined... "Amber Age" - When the key to space and time awakens, the shadow of the past quietly approaches, and the gears of fate have begun to turn.
