**Introduction to the work "Keepers of the Star Sea" (297 words)**
On New Year's Eve in the year 3000, a purple light curtain tore through the sky and rewrote the fate of mankind. Sunlight becomes a deadly weapon, and those who are illuminated turn into bloodthirsty monsters. Civilization struggles to deal with it in a state of foresight and hindsight. Zhang Ze, a retired special soldier, puts on a "light-hating suit" that can isolate light pollution, only to find that this disaster has long been engraved into the earth's genes - the mechanical hum from the ancient underground, the weird self-healing code in the virtual world, and the "new humans" who suddenly possess superpowers but age rapidly, all point to the fatal truth deep in the starry sky.
When the first tree of light rose from the ground, the entire solar system was being dragged into the endgame of a civilized war thousands of years ago. The alien beasts that devoured the city turned out to be the blockade of lower civilizations in the higher star realm. The alien spacecraft sleeping deep in the core of the earth held the key to rewriting the laws of physics. Zhang Ze was forced to shuttle between flesh and blood battlefields and quantum mazes, and glimpsed the shocking truth in the cracks of space-time distortion: those weird channels connecting galaxies are nothing but synapses of the universe itself.
The technology that mankind is proud of is just a speck of dust in the breeding experiments of advanced civilizations - this cross-dimensional survival war has all the scripts for destruction written long before the birth of mankind.
