Young Master Xu said, "That's easy. When the wedding ceremony takes place, the Yun family will have my blood. With the Yun family's abilities, as long as the blood's pull hasn't faded, tracking me down won't be difficult."
Xu Yi asked in surprise, "The blood's pull? So blood can be used to track someone because of this pull? And does this blood pull have a time limit?"
Xu Yi naturally knew that blood could be used to locate its owner.
But he didn't know the principles behind it, and this was the first time he'd heard of the so-called blood pull.
Young Master Xu said, "I can't explain exactly what this blood pull is. I only know that blood of the same lineage attracts itself. They say that even blood brothers who've never met can feel an inexplicable closeness when they meet for the first time. That's because of this attraction between their blood. Even if a single drop of blood falls to the ground and is split in half, the two halves still attract each other. Using secret techniques, one can rely on that attraction to find blood of the same origin. Of course, a person's own blood exerts a much stronger pull than a relative's."
"However, once blood leaves the body, it slowly dies, and its pull gradually fades. Usually, it disappears within a few months. Only secret techniques can preserve blood, and even then, it's difficult to keep it for long. That's why the Court Registry requires people to submit their blood for recording every year or two."
"I see. Brother Xu comes from a family with deep roots. I can't hold a candle to you."
Xu Yi sighed.
He meant every word. Aristocratic Clans had generations of accumulated knowledge, and their descendants learned so much simply
