Stain Era

In 2077, the earth is teetering on the edge of ecological collapse. When the nations of the Earth are fighting against each other for the last source of water and energy, an alien civilization called the "Cleaners" arrives. They do not attack humans, but quietly clean up polluted rivers, air and land, and then announce that the earth has been listed as a "cosmic pollution control demonstration area" and all humans must undergo environmental transformation within thirty days. When the renovation list was announced, there was an uproar around the world - the first person on the list was actually an official from a certain country's environmental protection department who had submitted false governance reports all year round. But what really alarmed the cleaners was the ecologist Evelyn hiding in the abandoned ocean observatory. 97.3% Of the abnormal resonance was detected in her brain, which was labeled as "cognitive pollution interface" - a thinking virus that once wiped out thirteen civilizations in the universe, and is the most perfect host on earth. The moment Evelin pressed the sample self-destruct button, she discovered three secrets: The cleaner's "purification" is actually a cosmic experiment lasting millions of years Her preserved gene-edited embryos are resonating with alien signals Deep in the ocean, a being that is neither human nor a janitor awakens. This is a war without smoke. The enemy doesn't want our land, doesn't want our lives, only our "wrong" rights. When perfect purification collides head-on with imperfect humanity, who gets to decide—whether the stain is a shame that should be erased, or a proof of its existence?
