The Puppet Death Energy was like a volcano on the verge of eruption, no matter how turbulent it was underground, the surface revealed nothing. Had it not been for the slight fluctuation at the moment the door opened, He Qing would probably have failed to sense it.
However, her visit this time was to help Xiao Xue, to completely allow her to dissipate her Heart Demon on her own.
Therefore, she couldn't directly interfere with the couple's thinking, aiming for immediate results. Only through subtle and gradual confusion could she truly achieve her ultimate goal. Otherwise, if she forced them to make changes against their will, and they relaxed Xiao Xue's studies for a moment, it would only be a stopgap. Before long, they would likely revert to their old ways. That was why He Qing went through so much trouble to gain the couple's trust.
But now, it seemed... it might already be too late.
