Dawn of Civilization: the Age of Stars

In 2200 AD, the orbit of the human home planet. The engine of the "Dawn" flagship spurted out light blue plasma flames, leaving behind the last ray of Earth's gravity. Captain Lin Yan traced the holographic star map with his fingertips. The Milky Way flowed like luminous ink, and tens of thousands of habitable planet markers flickered in the darkness. "Attention all fleets, coordinates are M-78 Nebula, target Pioneer signal source, set sail." Outside the porthole window, the rings of Saturn are like a belt paved with broken jade, and the asteroid belt draws a silver track in the gravitational field. Suddenly, a sharp alarm came from the detector, and a series of disordered pulses popped up on the screen - it was a signal that had never been decoded by humans, coming from an unknown star field on the edge of the star map. The frequency was exactly the same as the pioneer ruins discovered a hundred years ago. "Captain, the signal strength is increasing, like some kind of coordinate guidance." The communications officer's voice was vibrating. Lin Yan raised his head and looked out the window. In the distant depths of the sea of ​​​​stars, a purple nebula was slowly rotating. A huge metal outline vaguely appeared in the center of the nebula, like a cosmic beast that had been sleeping for hundreds of millions of years. From this moment on, mankind's first interstellar expedition is destined to be closely entwined with an unknown fate. And behind that string of mysterious signals, is it the dawn of civilization or the abyss of destruction?
