Under immense pressure, his strength had improved so dramatically that even Kakashi himself had never expected it beforehand.
Originally, he had merely wanted to incorporate Lightning Release Chakra into his swordsmanship and create a powerful move to deal with the Night Duke.
Yet by some stroke of fate, even his swordsmanship had broken through.
This surprise left Kakashi unable to calm his heart for a long while.
"Father, the swordsmanship you taught me all these years... today, I finally broke through!" Kakashi muttered, suppressing the excitement in his heart as he gripped the Short Sword in his hand again.
At the same time, Kakashi felt that holding the Short Sword now was completely different from before!
Before his breakthrough, Kakashi felt that he was merely using a sword.
But now, the Short Sword in his hand felt like a part of his body, as though he could wield it as easily as his own arm!
This also gave Kakashi even greater confidence that he could defeat the Night Duke.
After all, he had seen the power of that slash just now with his own eyes.
"I never expected your swordsmanship to achieve a breakthrough. That truly surprises me. Moreover, from that slash, I saw the shadow of your father, Hatake Sakumo.
But surely you don't think that a breakthrough in swordsmanship means you can deal with me now, do you?"
Controlling the Night Duke, Soji spoke in a deliberately surprised tone.
Of course, Soji was happy for Kakashi in his heart.
It could be said that Kakashi's name as a genius was once again shining upon Konoha's stage at this moment!
"Heh, who knows? But the second round is about to begin, and I won't let you suppress me like before!" Kakashi chuckled first, then spoke with a serious expression.
