Echoes of the Deep Sea Silence stared at the holographic screen in front of her, her fingers beating rapidly on the virtual keyboard. The dark blue data flow entangled her sight like seaweed, and every code told the secrets of this underwater city. Working overtime again? My colleague Sister Lin came in with a coffee cup. It was already two o'clock in the morning. It'll be ready soon. Shen Mo didn't even raise his head, his eyes fixed on the flashing red warning line on the screen [Gene sequence anomaly matching rate: 9997%]. Sister Lin sighed: You are just too serious. As mentioned above, those genetic samples of ancient humans were collected randomly, so some errors are normal. Silence did not speak. Of course she knows what's normal if it's just an ordinary error. But this sample... She pulled up another file, her fingers trembling slightly. That was the DNA record kept by the hospital after her father Shen Guoliang died accidentally during deep-sea exploration three years ago. The two gene sequences overlap perfectly like mirror images. It is impossible to mutter in silence. Her father had been dead for three years and his ashes were scattered into the Pacific Ocean. But now, a newly salvaged ancient human remains said to be from 30,000 years ago actually have exactly the same genes as him? The office lights suddenly flickered.
