Deep in the Earth, High in the Starry Sky

On April 1, 2050, the inauguration ceremony of "Yinghuo City", humanity's first Martian colonial city, aroused great excitement across the country. During the live broadcast of the ceremony, the signal was suddenly interrupted, and all remote electromagnetic wave communication equipment around the world failed. Organizations with the ability to receive and analyze cosmic electromagnetic wave signals have detected a sentence: "Human beings, the second big explosion of life on earth is about to begin. Please run with all your strength. I wish you can defend your title." Keep replaying. It was as if there was a ghost repeating the motto in the void. —— On this day, it seems that a certain higher-dimensional life is also celebrating an "April Fool's" day and playing a big joke on humans.
