For Jiang Si, using the Miracle Seed to transform into a Complete Witch is a path he must take.
No matter what kind of power, he never finds it excessive.
As a Nascent Soul, Black Dragon is already at its peak, perhaps before transformation, the realm will have to be maintained at the Initial Bloom after the [foreword][middle][afterword] breakthrough from [Peak Great Perfection].
Even if he uses the real body of a Nascent Soul with the complete Witch Transformation Mysterious Skill, the innate deficiency makes it impossible to utilize magic sense; no matter how much magic power he accumulates, it can only turn several dozen more times at the early stage of Full Bloom. Without reaching the Extreme Realm, he can't break through and, despite having a body full of magic power, his status won't rise.
It may sound absolute, but Jiang Si believes he has a fairly good understanding of Full Bloom.
