The moment Elder Droman achieved his breakthrough, All Nascent Soul and above level experts in tens of thousands of kilometers noticed his presence. One must understand that Soul Transformation Realm experts are extremely rare in the Country of Jialin. Even put the Sects and the Royal Family experts together, the total number doesn't reach 10! No one could tell why they could feel that, though. It has always been a mystery.
Dalamu Sect had only Mia since her Master, the hidden ancestor, is in the realm above. The Royal Family has two. The other Sect that also has two is the Lagan Sect. As for the other three sects, they only have one each! Droman has just become the 9th one here.
