Immortal Body

In 2029, human consciousness uploading technology breaks through the final bottleneck, and "immortality" becomes a commodity with a clear price tag. Rich people can purchase "spare bodies" - unconscious human bodies cultivated by bio-3D printing, into which consciousness can be transferred after the physical body dies, achieving unlimited lifespan. Shen Du, a bioethics officer who specializes in "destruction" work, has a daily job of confirming that the vital signs of the cultured organisms are normal and pressing the destroy button. He has been doing it for six years and has never hesitated. Until one day, during a routine examination, he discovered that the cultured body numbered "DK-2049" had a flash of theta waves on the electroencephalogram during deep sleep monitoring - that was a sign of dreaming. How could an empty shell without consciousness dream? Shen Du began a secret investigation, and he discovered that a considerable part of the cultivated bodies he destroyed with his own hands may have always had consciousness. What's even more frightening is that the technology company "Hengsheng Group" has known this for a long time - they are even deliberately cultivating bodies with conscious abilities, because that kind of consciousness transfer has a higher success rate. As for Shen Du himself, he had already changed his body after an "accident" three years ago. His wife said that after changing his shell, he became different. I no longer like coffee, no longer have nightmares, and no longer remember my daughter's favorite fruit. Shen Du began to doubt a question: Is the "me" sitting in this body really the original me? Or am I just a qualified and obedient spare body with implanted memories?
