What Does It Mean That the Universe I Live in Is a Neutrino?

Cheng Kuan lived for twenty-eight years, and his greatest achievement was to save 12,000 in a certain bank. Until one morning at four o'clock, a ball smashed through his ceiling. Out of the ball comes a human - no, an AI. It told Cheng Kuan: Your entire universe, from the Big Bang to heat death, from the Milky Way to the instant coffee in your hand, is just a neutrino in the eyes of a higher-dimensional civilization. An ordinary neutrino marked as a exploitable resource by the company "Abyss Entertainment". The universe is about to be transformed, developed, and turned into a sandbox for the entertainment of "players" from another dimension. And he is the first intelligent life in this neutrino discovered by AI - a statistical miracle, a system error, and a bug that should not exist. Now Cheng Kuan only has one question: If a carbon-based creature in a neutrino raised its middle finger to the entire mother universe, would anyone see it? He doesn't know the answer. But he decided to give it a try.
