Xing Youran looked like a cat that had caught a mouse, utterly smug. "You really are a fake! You don't even know about the Bloodline Verification Stone in our Grand General's Estate."
Xing Beiluo asked, "A Bloodline Verification Stone?"
Old Madam said with a smile, "Yes, the Bloodline Verification Stone. This stone contains a drop of our ancestor's Essence Blood. It can only be activated by someone who shares the exact same bloodline, so there is never the slightest chance of a mix-up. If you drip a drop of your blood onto the stone, it can sense the holder's lineage. If it belongs to the Xing family bloodline, it will be absorbed, causing the stone to glow. The purer the bloodline, the brighter the stone shines. Of course, a trace of it can also be detected after sharing a bed with a child of the Xing family."
