Dong Yubai was about to retort when he heard Cao Qiupu nod:
"Indeed, I searched for a long time today but couldn't find any trace of this person."
"Are you talking about the person who left a palm seal on the stone monument?"
Du Hanyan asked at this moment.
Chu Qing and Cao Qiupu exchanged a glance and nodded simultaneously.
The palm force of that person was extraordinary. When Chu Qing encountered Cao Qiupu and Du Hanyan, he initially thought it was left by them.
But later, he felt something was amiss.
Cao Qiupu was chasing the white horse; he didn't even know there was an illusion array here, let alone left a mark on the stone monument.
As for Du Hanyan, it was even less possible... The person who left the palm seal had a wide palm; Du Hanyan's delicate hands couldn't leave such a large palm seal.
And neither Dong Xingzhi nor Dong Yubai had that kind of power.
