Nebula Watch

In 2280 AD, mankind has entered the era of interstellar civilization. Astrophysicist Lin Xiaoyu received a mysterious pulse signal from the NGC-2359 nebula at the edge of the Milky Way at the data center. This signal is stable but violates known physical laws, and its propagation speed is suspected to exceed the speed of light. What's even more disturbing is that the coordinates of this signal exactly coincide with the location where his father, Professor Lin Jianguo, was last studied after he mysteriously disappeared three years ago.
