At this moment, Du Youqian's Heart Lake was a seemingly placid surface.
But should anyone try to pry into his memories, that calm lake surface would part, revealing the sharp Sword Intent hidden beneath to counterattack.
According to Du Youqian's estimation, even a Core Formation Ancestor, if caught off guard, would likely suffer a small setback.
Although it was only a small setback... this was actually an astounding achievement.
Normally, a Core Formation Ancestor could kill a Foundation Establishment Early Stage Cultivator as easily as an ordinary person swatting a mosquito.
And a mosquito, even trying its hardest, could at most leave a few bites, causing no real substantial harm.
But Du Youqian, who had cultivated the "Heart Lake Sword Technique," could... under specific conditions, genuinely harm a Core Formation Ancestor.
"Broken Water." This was the name of the Sword Intent Du Youqian had comprehended.
Unstoppable, unbreakable, it could even cut through water.
