No matter how violent the Spiritual Energy is, it becomes extremely docile in front of Xue An.
Thus, Xue An proceeded to do two things. First, he controlled the violent Spiritual Energy, making it as gentle as the spring breeze.
Second, he infused the Spiritual Energy into Ren Ning's body, reforming her physique and meridians.
This process is essentially the indispensable Foundation Establishment Period everyone undergoes in cultivation, though the duration varies depending on talent.
Back in the day, Xue An took a full three months for his Foundation Establishment when he first began his cultivation journey.
That speed was already considered top-notch.
No matter how extraordinarily gifted someone might be, the Foundation Establishment Period cannot be less than two months, as the flesh is too frail to bear the transformation by violent Spiritual Energy and may suffer damage if mishandled.
Thus, people can only proceed with cultivation cautiously.
