Chapter 420: Bloodline Hybridization; The Fallen No. 18_2

"Whimper————" No. 18 hid behind Lu Ran and said, "Manager Ying, I'm really thinking for you. If I had better control over the Blood Energy Source, a single bottle of blood might summon 100 Heroic Spirits, but if the conversion rate is too low, a whole barrel might only be enough for one summon."

"You need to think carefully, analyze it well!"

Manager Ying: "..."

So, I should even thank you for this?

"That's too much; angels represent purity in the Star-Moon Continent, and you, this little Mechanical Angel, dabbling in both souls and blood, you're practically the definition of a fallen angel!" Manager Ying pouted.

"Alright, alright," Lu Ran said. "But you do have a point. Let's challenge this Vampire Queen then... Speaking of which, vampires..."

Lu Ran stroked his chin, wondering if the vampire his parents had raised was still abandoned on Reaper Island.
