"Now hold on just a minute! You mean I'm your test subject?" Worried, Lucas took a few steps back.
"No, haha! You are too valuable to lose."
At that assuring reply, Lucas breathed a sigh of relief. But just to confirm, he asked again. "Really? So I won't be your human trial?"
"As I said, you are too valuable to loose Lucas. What if mixing your DNA with Willburn family's alter your biology to such extent that it would create something new? In that case, I won't be able to revive your or retrieve your ability."
That answer made sense. However, Lucas couldn't understand one thing, so he decided to voice his confusion.
"Wait, you said you completed all the necessary theory part right? So if you've already studied their biology, why not just kill them?"
At that question, Sam couldn't help raise an eyebrow in astonishment. He was genuinely impressed by Lucas insight.
