Perseverant

"I'm not done yet." Rui smiled. "I will test my new offensive technique to my heart's content."

"Hah, bring it on then." Master Vertol grinned. "My defense isn't just for show."

Although he said that, he was still deeply stunned at the revelation that Rui had cracked the principles of the technique upon his first observation of them three years ago.

Rui had also managed to successfully inflict damage on him, unlike last time. This showed that this technique alone surpassed his previous offensive technique. It was a tremendous boost that the Void Prince treated as entirely normal and mundane.

In other words, he was accustomed to such tremendous growth that even this was hardly worth remarking to him. To Master Vertol, this was hard to wrap his head around. The only time in his entire life that he had made such growth was when he mastered the Yin-Yang Shield technique through the secret methodology of the Gen Temple centuries ago.
