Upon hearing this, Mogwin hurried along as he spoke:
"Ten million times? Are you sure there wasn't an error in the experimental data?"
"Absolutely not! When the results first came out, I thought something must have gone wrong, too. I ran the tests three more times, and got the same results every time!" Hilbert said excitedly.
The perfect blood sample they had failed to develop after more than a decade of research was now right before them.
"Begin the experiment immediately. Terminate the experiments on those thirty subjects and inject all of them with the new blood," Mogwin ordered at once.
"Professor, what dosage should we inject?"
"Keep it at one-tenth of their total blood volume. That's the safest amount. Any more, and the subjects risk dying," Mogwin said gravely.
Hilbert wanted to say, What does it matter to us whether the subjects live or die? But seeing how serious Mogwin was, he complied.
They entered a specially constructed room. Its walls were incredibly sturdy, made entirely of cast steel, except for one wall of specially made tempered glass. The ceiling was fifteen meters high, designed to accommodate the average height of Titans other than the Colossal Titan.
After returning to human form, Roald looked at the subject before him, a robust man in his prime. Blood was being continuously drained from his body, leaving him increasingly shriveled as his vitality ebbed away, until he resembled an old man on the verge of death.
Rundstedt observed from the other side of the glass.
"Begin the injections!" Hilbert ordered.
Several staff members immediately got to work, inserting needles into the subject.
Roald watched his own pitch-black blood slowly enter the subject's body through more than a dozen needles.
As Roald's blood entered him, the subject's eyes snapped open and bulged as
