As Yang Lujia said, Xia Hua's blood contained a hint of the void—just like his. This even surprised the people who heard him. However, they almost knew nothing of the void. Hence, their reactions weren't that intense.
However, Yang Lujia knew something of the void from Brownie. The void was said to be where all the strongest living beings reside. Each of their strongest could destroy the Five Realms with a wave of their hands.
Even Yang Lujia could not do that. He could destroy the lower realm with ease, but it was hard to say in the higher realms. After all, the higher he ascended, the more difficult it was to distort the rules, especially the rules he had vaguely felt before—that rule was especially almost invisible to his eyes. He could slightly control it, and it was the minimum he could do.
