After All Mankind Has Eternal Life

In the near future world, a mysterious being who calls himself Y plays a video called "A Letter to All Humanity" on all electronic devices in the world at the same time. At this point, Y cells have spread to everyone like the flu, and all humans have achieved immortality under its influence. Some people say that Y symbolizes a tree, because Y cells can absorb the energy of the sun like plants, allowing people to live without eating; Some people say that Y is God. When you stand at the foot of the giant statue of God and look up, His open hands and body form a "Y"; Some people say that "Y" seems to be pronounced the same as "outer" in Chinese, and is it the so-called Cthulhu Outer God? No one is not curious about who or what God Y is. But people know that when He waves His hand, those unworthy ones who are deemed "unworthy of eternal life" will grow old and decay! So the "eternal life switch" became the greatest authority in this era, no, the greatest authority in history! It is the most perfect tool for governance, the radiance that bestows individual divinity, and the ladder that can satisfy any ambition! "Want it? Just kill me." A scheming and vigorous battle for the immortality switch begins! In a prison isolated from everything, including Y cells, Jing Hengyu had no idea that the age of immortality had arrived. It's been three years. If I can't escape, I'll be eighteen and I'll miss the college entrance examination...
