Intrusion of Abnormal Thoughts

That day, a gap opened in the sky. On Christmas Day 20XX, the world looked up at the same time - a second moon appeared in the night sky. It is not a celestial body, but a black polyhedron with ferocious edges and corners, spinning silently in low-Earth orbit. The international community called it the "Eridanus Fragment" and promised that it was just a close call. Someone lied. Chen Wang, a high school student obsessed with astronomy and strange stories, discovered during his escape that the diary he wrote intermittently after surviving the 226 Incident could predict these death rules. What's even more frightening is that his father, Chen Zhiyuan, one of the first astronomers to discover the "fragments"... Seemed to have known everything for a long time, but he left a cold warning: "Some doors cannot be pushed open." But the door is already open.
