Now Han Sen understood why Qiao had bought him. With that dagger, you could kill xenogeneics even if you weren't a Noble.
Still, it wouldn't work if given to the average soldier. They lacked the speed and physical prowess to match a xenogeneic, and they would likely end up killed before ever getting a chance to use the weapon.
Qiao must have studied the fight between Han Sen and the xenogeneic and determined he was capable enough to wield the dagger effectively. It was the reason why she had bought him.
"So pieces of xenogeneics can become weaponry?" Han Sen asked as he fiddled with the Rhino Horn Dagger.
"There are many different xenogeneic materials, and most can be used to create weapons," Qiao answered without even having to think.
"Can we eat them?" Han Sen smiled, as if he was joking.
