Playing To The Strengths
Duncan opened his eyes and a slight glimmer shined in them.
He had just pursued the information provided by the teller. After inducing his consciousness into the jade slip, a deluge of information appeared in his mind. Duncan had pursued them calmly after the jade slip destroyed itself.
Luckily for Duncan, he didn't need to get higher-level information. The question he needed the answer to was already present in the jade slip that was provided to him.
Duncan got to know that the mark on Leia's back was called the spirit mark. A Nascent Soul cultivator had once researched the spirit mark and found out that it was a kind of bloodline lock. The only time the spirit mark will vanish will be when the bloodline lock was unlocked and the descendant in question achieves enough bloodline evolution.
