Zhou Shu's confidence really intimidated Yao Qing.
He frowned and stared at Zhou Shu with a solemn expression.
This human, whose spiritual essence cultivation was clearly only at the third rank of the Martial Dao, was a mystery to him.
Yao Qing could still vaguely feel pain all over his body from the battle yesterday.
This human's body was even stronger than that of demons!
It went against everything he knew about humans.
Moreover, in the short exchange just now, Yao Qing could tell that this human's saber technique attainments were far above his.
As for how far above, he couldn't tell.
Now, he even suspected that this person's spiritual essence cultivation was not at the third rank at all!
It was impossible for a third-rank martial artist to be so strong.
Even so, Yao Qing didn't believe that Zhou Shu could easily kill them!
