I immediately became certain.
The "wave" surging toward the "little boat" I was aboard, formed upon the "dark sea," was none other than the "mana fluctuations" Zhu Shi and Lu Youxun always spoke of.
This was the first time in my life I had felt such intense fluctuations, like I had always lived indoors without any wind and had now finally stepped outside, feeling the strong breeze against my face. Now, without needing to imagine any "sea" or "little boat," I could clearly sense these fluctuations in a natural and normal state.
Was this the mana fluctuations of a Great Success Rank demon hunter that Zhu Shi mentioned?
But where did it originate from?
It wasn't coming from the old Human Bureau base. The moment I opened my eyes, I saw Mazao beside me with an expression of shock and dismay, as she looked toward the southeast. The source of the mana fluctuations lay far in that direction, at least a dozen kilometers from where we were.
"Great Success Rank?"
