Just how much Source Blood Murphy has left, is a question only he himself knows the answer to.
He's actually unsure what purposes this thing holds, aside from breaking a bloodline contract and strengthening a vampire's powers? But, without a doubt, it's a good thing! And since it's a good thing, he has to hoard more of it for himself.
At this moment, when confronted with Cui Si's question, Murphy gave her a blink in the darkness before responding:
"Guess?"
"You...annoying little bugger, your grand duchess is asking you a serious question here."
Cui Si seemed rather taken aback for a moment.
However, the dynamic between the two of them that had just begun to shift seemed to revert back to the previous casual and affectionate atmosphere due to Murphy's playful remark. Cui Si let out a sigh of relief - she herself wasn't even sure what she had been nervous about.
The grand duchess huffed and beckoned Murphy over with a finger.
