After forming the Rasengan, Uchiha Yin kept working, infusing it with Lightning Release Chakra Nature Transformation.
Yin possessed Chakra of all five natures, but his understanding of Lightning Nature Transformation was the deepest. The Rasengan he made with it was also his strongest.
The little sphere, once vivid blue, blazed with dazzling white light.
The Rasengan suddenly doubled in size, becoming a massive ball of electricity wreathed in countless arcs of lightning.
It was like a star surrounded by countless planets.
The Rasengan was the star, and the arcs of lightning were the planets orbiting it.
With the technique complete, Yin hurled the Lightning Release Chakra-infused Rasengan at the two fleeing Ninja.
The Rasengan struck the rabbit-faced Ninja in the back before he could react.
It punched straight through him, then exploded.
Boom!
The ground shook violently. Waves rippled through the rock, spreading outward in layer after layer from the Rasengan's point of impact.
A dense web of writhing lightning instantly covered the entire area.
Countless flashes lit up the sky, staining it the color of lightning.
The lightning lasted nearly a minute before gradually fading. By then, the ground was charred black.
Everything within the reach of the Lightning Release Chakra-infused Rasengan had been destroyed.
A vast clearing had opened in the middle of the forest.
"Yin, what happened?"
Kushina, Mikoto, and Tsunade arrived just then.
"Oh, you're all here? What about the merchant caravan?"
"Don't worry. My Water Release clone is there. It only has a tenth of my strength, but an ordinary opponent still can't beat it."
Tsunade spoke with complete confidence.
"But what happened here? Did you do this?"
Seeing the barren expanse before her, Tsunade looked stunned.
Lightning still hung thick in the air, and stray currents continued to crawl across the ground.
