Reason

Erick Von Nigellus was surprised when the fragile-looking young lady of the Valyenor Ducal House obliterated all the target trees he had made for her. It was totally unexpected.

If she had trained with other students, they would have been awed or terrified of her for being able to do that on the first try.

Some of the students still struggled to reach the third tree even after some training. Only students from the Nigellus family were able to do that since they were blessed with much more mana compared to others since birth and were taught magic at a young age.

'Who would have thought that she packed so much more destructive power than her older brother?'

If she had used that attack on the battlefield, she would have been able to eliminate a great number of enemies who were not using magical items to protect them from magic attacks.

If Stella was trained properly, she would be a powerful mage in the future.
