Seiya's Water Release ninjutsu had been powerful, but defeating Deidara with Water Release alone was obviously impossible.
To better capitalize on the advantages of his Explosive Clay, Deidara had just molded a new model better suited to the environment.
Most of his previous Explosive Clay models had been designed for aerial combat, but in this environment, using those old models was clearly no longer viable.
The C2 Whale he had used earlier was a new model he had molded from Explosive Clay.
Not only could C2 Whale swim swiftly through water, it could also automatically track and lock onto enemies.
Although explosions from beneath the water were somewhat weakened by the resistance and cushioning effect of the currents, reducing the power of the Explosive Clay,
naval combat was not without its advantages over aerial combat. Explosive Clay lurking deep underwater was far harder to guard against.
Unless one possessed the Byakugan's ability to see through things or the Sharingan's ability to perceive Chakra flow, ordinary shinobi simply could not predict his attacks.
And if the power was insufficient, he only needed to mix in higher-grade Chakra and mold a stronger model.
"Water Release: Water Clone Jutsu!"
To prevent Obito from using Kamui to forcibly pack up and take away Isobu while he fought Deidara, Seiya formed hand seals and created a solid Water Clone on the water's surface.
Seeing Seiya expend a great deal of Chakra to create a solid Water Clone, Mei Terumi frowned. "If he isn't Madara Uchiha, I can deal with him myself."
Seiya was indeed powerful, but Mei Terumi did not want him to shoulder every responsibility alone.
After all, she was not some ornamental female shinobi. She was the Fifth Mizukage of the Hidden Mist Village!
"Don't forget our original objective. Focus on sealing Isobu.
