For example... upgrading Jade Rasengan into an S-rank ninja's Spiral Cultivation Technique!
Thinking of this, Mirai looked at Rock Lee's hand and could not help frowning. "Rock Lee is wearing a straw raincoat. I really miscalculated. He can't feel anything at all. Right—what if, at the instant I cancel the Yin-Yang Sword Technique, I pour in a massive amount of spiritual power to create an enormous Jade Rasengan? Could that be possible..."
Mirai looked at the distance inside the tornado. The tornado formed by his sword technique was only one centimeter away from him. He could not help frowning.
"No, the distance is too short. The moment I cancel the Yin-Yang Sword Technique, I'll probably be swallowed by the elements inside the tornado."
"What should I do... What should I do..." Although Mirai had realized that exchange skills could also be strengthened through his own training, that did nothing to help his current predicament.
If Jade Rasengan could be strengthened on its own, could sword techniques be used as well? A flash of inspiration struck Mirai. "The attack power isn't high, but meteors are fast. If I use the Meteor skill and infuse the sword technique into the meteor, could I kill the sword technique and break through the tornado with the meteor at the same time I cancel the Yin-Yang Sword Technique?"
Too dangerous...
Mirai felt that it was not merely dangerous—it was far too dangerous!
However, when Mirai sensed that his spiritual power had fallen to 500 points, panic began rising in his heart as well.
"Hah..." Mirai's eyes gradually reddened, and his hands had become sore from swinging the Divine Wind Sword. He could not hold on any longer!
"Rock Lee, I'm going to make a break for it. Success means life; failure means..."
"I know." Before
