To be honest, according to what the Primordial Talisman Pen said before, the transition for Integration Stage Cultivators to ascend to the Mahayana Realm is a massive threshold.
Countless Integration Stage Cultivators are stuck in this realm, unable to break through for a long time.
Because to ascend to the Mahayana Realm, one must gain the recognition of the Law Origin and perceive a particular law to a certain extent to truly break through.
However, ordinary Integration Stage Cultivators, even if their lifespans are completely exhausted, cannot gain the recognition of the Law Origin.
In this way, no matter how long they cultivate, it's impossible to break through.
But it's different for cultivators who practice the Thirty-Three Celestial Spirit Talismans.
