Of course, this is only a legend.
After all, in the entire domain of the "room," there has already been a very, very long time in which no one has advanced to the Primordial Realm. To advance to the Primordial Realm at this point is no longer merely a matter of whether one's talent is sufficient, but a matter of whether one's fortune is sufficient. Therefore, when the Primordial True Person decided to go beyond the palace walls this time,
it was not merely because Ye Tianfan had obtained the Chaos Divine Pearl and the Chaos Treasure Lotus. After all, with only these two Magical Treasures, the Primordial True Person would not have given rise to the idea of entering the world outside the walls. He would even, even if Ye Tianfan suggested it, carefully ponder over it.
