Mirai took a deep breath. Though he had already reached his limit, the infusion of spiritual power did not stop.
"Expand... condense... control... rotate..."
Mirai slowly closed his eyes, his focus becoming even more concentrated. At that moment, his entire state seemed to enter a void-like realm.
With a sudden bang, the amount of divine power being infused abruptly increased. The Big Ball Rasengan instantly expanded by a full circle. Mirai's hand trembled slightly, and the Big Ball Rasengan trembled as well. After three breaths, the Big Ball Rasengan shook before finally stabilizing.
"Haa..."
Mirai slowly let out a breath, then opened his eyes with a smile at the corner of his lips.
"1.7 times the size..."

Mirai was delighted, but he did not continue practicing. Relaxation and moderation were the most effective methods of training.
"Two days ago, I could only use a Jade Rasengan at 1.5 times its size, but now I can use 1.7 times."
With a thought from Mirai, the Jade Rasengan suddenly broke apart and turned into specks of golden light.
Afterward, he stood up in satisfaction, loosening his muscles and bones. With a movement of his right hand, the Demon Sword appeared in Mirai's grasp.
Divine spiritual power slowly flowed into the Divine Wind Sword... Supreme Divine Sword Art, God Destroyer!
100...

130...
140...
The infusion of divine spiritual power suddenly stopped. The Divine Wind Sword radiated terrifying power and light as it trembled slightly. A powerful current of air spread from the Divine Wind Sword, gently lifting the ends of Mirai's hair.
"Disperse!"
Mirai shouted softly. A loud roar rang out, and then the powerful aura vanished.
Mirai drew the Divine Wind Sword
