Only Michael possessed Perfect Blood. The odds of that were extraordinarily low.
Perfect Blood, this miraculous substance of legend, not only contained an immune capability humanity had never seen before, but also concealed the key to unlocking life's potential.
The root of this uniqueness was deeply embedded in Michael's genetic code, a rare result of millions of years of natural selection intertwined with genetic mutation.
The reason Michael's Perfect Blood was so rare was largely due to the limitations of genetic technology at the time.
In that era, genetic research was still in its infancy. Scientists had only a shallow understanding of genes, and genetic manipulation relied even more heavily on the natural reproductive processes of living organisms.
This meant that unless it was passed down through direct bloodline inheritance, the traits of Perfect Blood were almost impossible to replicate or transmit to the next generation.
Thus, although Michael's family had countless descendants, not one of them inherited this gift from heaven.
However, the wheel of history had always rolled forward, and scientific progress had never ceased.
With the rise of artificial insemination and in vitro fertilization, the field of genetics ushered in a revolutionary breakthrough.
These technologies not only greatly expanded humanity's reproductive options, but also opened entirely new paths for the treatment and prevention of genetic diseases.
Through non-natural mating methods, artificial insemination injected selected sperm directly into a woman's body, achieving precise control over reproductive cells.
In vitro fertilization pushed this process to the extreme, allowing scientists to perform all manner of operations on fertilized eggs in a laboratory environment, including but not limited to Gene Editing, screening, and enhancement.
It was precisely on the basis of these advanced technological methods that researchers began tackling the problem of passing down Perfect Blood.
They first extracted high-quality reproductive
