The smoothed areas sank downward, making the entire stone wall very uneven.
And as they went further up, they could see that there were more and more uneven places.
It was as if someone had deliberately erased those characters bit by bit.
"Could the erased engraved text reveal some kind of secret?" Yang Yan couldn't help but think.
If there were no secrets, why waste time erasing the engraved text?
"Master, my Profound Qi is running low!" came Miao Yin's voice at that moment.
Yang Yan looked around because he had climbed to a high point on the Abyssal Sky Demon Cliff.
The surrounding Wind aura was even more fierce compared to below.
It had reached the realm of a three-layered Wind aura!
Even Miao Yin, who had reached the early stage of Dragon Transformation Realm in cultivation, could not withstand the sharpness of the Wind aura.
Therefore, she used Profound Qi to protect herself, blocking the blowing Wind aura.
