"When the genetic chain of all mankind began to collapse, I personally put a monitoring collar on my sister."
In the autumn of 2077, on the 1095th day when a dark matter storm swept across the earth, my electronic prosthetic eye scanned the golden lines deep in my sister's pupils—a sign of the late stage of gene disintegration syndrome. As the last genetic lock doctor in the ruined city, I know better than anyone else: her DNA chain will completely break in 72 hours and turn into a pool of fishy blood.
But this time it's different.
She began to predict.
At 04:17 every day, a mechanical synthesized sound will be emitted from her throat, reporting a series of coordinates. We followed the coordinates and found military inhibitors, quantum batteries, and even a frozen corpse with the words "Ark Project-First Generation Experimental Subject" engraved on it. Until that day, the coordinates pointed to the Annihilation Clock** underground at the Salvation Army headquarters, and the holographic projection displayed a dazzling countdown: [Remaining for the disintegration of all species: 30 days].
"Lin Shen, there is a gene lock code hidden in your right arm prosthesis."
When the dying mutant wolf king uttered these words, my survival system suddenly went into chaos. Those forgotten memory fragments began to revive: the rainy night three years ago, the screams in the Salvation Army laboratory, and the touch of Dr. Chen Xuan piercing the black crystal tablet into my spine.
At this moment, I held the swarm of nano bugs that I took out from my sister's skull, and they spelled out two lines of blood letters in the air:
[To save her, all ecological domes need to be destroyed]
[Become a new human being, or be buried with the old world]
