The Nascent Soul is like a newborn infant, imbued with the cultivator's immense power, yet incredibly "fragile"!
This fragility is relative to the vastness of heaven and earth.
The Nascent Soul yearns to merge with heaven and earth but fears blending too deeply.
If a cultivator becomes too absorbed in their cultivation, and the Nascent Soul interacts too deeply with heaven and earth, it can easily be assimilated completely, losing oneself.
Thus, the Sea of Qi evolves into a Purple Mansion to protect the Nascent Soul, preventing it from being exposed and assimilated by heaven and earth.
Therefore, the thicker the barrier, the more relaxed the cultivator feels when cultivating, and the faster the cultivation speed.
An illustrative example would be flowers in a greenhouse.
With no wind or rain to batter them and suitable soil, they naturally grow vibrant.
But Luo Chen knows well what greenhouse flowers imply: they cannot withstand adversity.
