That night, thanks to the intensive training accumulated by thousands of shadow clones, Naruto managed to perform Chidori without hand seals!
Naruto was only human, after all. After days of rushing about and training like a madman, even his chakra finally gave out.
After resting for a day, he recovered his strength and resumed training while helping Kisame search the ocean.
Three more days passed, and he mastered Chidori's various shape transformations, becoming a Lightning Release expert!
But being an expert was only the starting point.
Next, Naruto threw himself into training Purple Electricity, forgetting both food and sleep!
The process did not go particularly smoothly.
Purple Electricity required mixing an appropriate proportion of Yin Release into Lightning Release.
For one thing, Yin Release was unfamiliar territory to Naruto, who had never possessed it in his previous life.
For another, he could not pin down the right proportion of Yin Release to add.
This made his early progress slow.
Fortunately, his experience balancing chakra while training the Tailed Beast Bomb in his previous life came to his aid...
After repeated rounds of trial and error, Naruto finally got the hang of it!
That night, Naruto stood on the muddy ground, a mass of purple lightning coiling around his scarred left hand!
Ten shadow clones stood before him!
Naruto called out firmly, "Come on...!"
The ten shadow clones formed hand seals together!
-Lightning Release: Lightning Tiger Massacre!
"Awooo...!!!"
Ten lightning hounds formed from ordinary Lightning Release merged into a mighty lightning beast. Guided by the lightning cords in the shadow clones' hands, it lunged at the original!
Slash!
But Naruto merely gave a casual sweep of his left hand, which was cloaked in Purple Electricity.
"Awooo...!!!!!"
The lightning beast dissolved with a miserable howl. Not only that, purple arcs traveled along
