What is the Extreme Yin Wall?
The Yin-Yang sect's most treasured relic.
When breaking through the seven extremities from the nine extremities in Yin-Yang, the Extreme Yin Wall must be used for cultivation.
Even someone as formidable as the Elder Heng Yan couldn't defeat Liu Laoliu...

And now, Xie Tian has a piece in his hands.
This matter is worth pondering.
Upon confirming that the black stone pillar constantly eroding the space of his storage ring was indeed the Extreme Yin Wall, Xie Tian's mind was flooded with guesses like stars in the sky.

Why does Outer Heaven Palace seemingly undervalue the Extreme Yin Wall?
