Rebuilding the Definition of Humanity in the Zombie Age: Sun Rain

The sun, the star that once gave the earth unlimited light and heat, is quietly dying. Modern science has long calculated its slow extinction trajectory, but the universe never follows human expectations. A "solar flare explosion" without warning tore apart the calm, and violent X-rays, ultraviolet rays and charged particles poured down like a shower, which humans call "solar rain". When the first "rain" fell, people were still unaware; after the second "rain", the world was completely different. Plants adapt silently to the radiation, and animals use their instincts to dive into the darkness. Only human beings face the most cruel selection in "sunbathing" - death or mutation. Some people who have been exposed to the "sun rain" wither in pain, and some mutate into patients with "flare disease": their skin ulcers, they go crazy, and they bite the same kind of people like evil ghosts. The order of civilized society collapsed in just a few weeks. The survivors called them "zombie", and the real terror may have just begun... As the survivors struggle to survive, the survival of human civilization stands at a crossroads. Is it to linger on and recreate the old order, or to reshape genes in the radiation and welcome a forced "leap"? And are those patients with "Flash Syndrome" degenerate monsters or the prototype of a new evolved species? The answer may be hidden in a mysterious underground laboratory, or in the scarlet eyes of a "zombie", or maybe - only the next "sun rain" can give the final judgment.
