Why was the Spiritual Foundation so important? It was because it was through it that cultivators communicated with the Heavens.
When a human cultivator was born, they would be gifted with a set talent. But, how could a baby boy or girl withstand such valiant potential? Their bodies are too frail and their experience too thin.
