Rebirth from the Doomsday Catastrophe

In a desolate desert, a world without sunlight, Chen Guang was running on the desert, and there was a figure chasing him behind him. Upon closer inspection, this figure turned out to be a blue-sky bull, which was actually 3 meters tall and 4 meters long. It looked like a giant monster. Chen Guang looked back while running and was so frightened that he quickly continued running. Ten years ago in this world, Chen Guang was an 18-year-old high school student. On a hot summer day, while his classmates were still taking a nap, suddenly there was a loud noise in the sky, a crack appeared in the sky, and the sun seemed to be swallowed up. Suddenly the whole world became gray, and it felt like the sun was setting. The students were woken up by the noise. Looking at the scene in front of them, each one seemed to be stunned. The world suddenly became quiet for a few seconds, and then the whole campus let out a roaring scream. At this time, there was a smell in the air. This smell was indescribable, as if it had never appeared in the world. At this moment, the crows hovering in the sky of the campus suddenly became stiff, and a bunch of crows came from behind.
