The first layer of the Wind Tao Prohibition was broken in just three days, which was relatively easy by comparison. It is known that even for a Profound Immortal, if they were to attempt breaking this prohibition, it would take at least ten years if they're fast, and it might take hundreds of years if they're slow, or they may never break it at all.
Of course, if someone similarly condensed Wind Tao Marks as powerful as those in Lv Zhong's Sea of Consciousness, it might be possible to break or even absorb the origin of the wind power within a few days.
But how many in the Immortal World possess Chaos Spirit Treasures? Because only those with treasures of Chaos Spirit Treasure level and above have Great Tao Restraints within their bodies.
