Ask for the title of a fantasy novel

The storyline was like this. In the early stages of the main character's academy, no one could learn the spells of the 5 Elements as long as they had 3 attributes. In the end, the main character's attributes were all 2, so he could not learn any spells. However, the main character was born with the Summoning Element (he did not even know it in the early stages)... In the end, he became stronger…That's about it. Those who know the title of the book give me a thank you
The era of the book he was looking for was the era of magic, not the era of summoned beasts. The protagonist had a pet kitten by his side. It was a super powerful summoned beast (Nine-tailed Fox). When he found it, it only had three tails.

Answer 1

The title of this novel was Battle Through the Heavens.
