How to Increase the Water Volume?
It's simple—just use ninjutsu!
"Have you heard of the Water Release: Exploding Water Colliding Wave?" Haruto Saito tilted his head and asked Tsunade.
"Of course," Tsunade replied. "It's a B-rank ninjutsu, performed similarly to the Fireball Jutsu. However, instead of fire, it expels water. If the user has enough chakra, the released water can create a small lake! Are you planning to use ninjutsu to store water in the lake?"
"Of course, what else?" Haruto Saito smiled slightly.
"Wishful thinking!" Tsunade scoffed. "Although the Exploding Water Colliding Wave produces a lot of water, compared to this lake, it's insignificant! The increase would be barely noticeable!"
The jutsu could only create a small lake, which was far from enough compared to Tide Listening Lake.
Based on calculations, the water volume produced by the Exploding Water Colliding Wave was about 200,000 to 300,000 cubic meters. Meanwhile, Tide Listening Lake held a staggering 200 million cubic meters of water!
After all, it was only a B-rank ninjutsu.
"The Exploding Water Colliding Wave isn't enough—it's far too little!" Haruto Saito admitted, then added, "But the Great Exploding Water Colliding Wave can work! As long as there's enough chakra, you can create as much water as you want!"
Tsunade was momentarily stunned and frowned. "Does such a jutsu exist? Does it?"
The first question was directed at Haruto Saito, while the second was aimed at Hattori Ryuya.
Hattori Ryuya, a master of all chakra natures and an expert in Water Release ninjutsu, could be considered a specialist in the field.
"No," Hattori Ryuya shook his head.
"No? Then we'll just create it." Haruto Saito grinned.
Does the technique really not exist?
Wrong!
It does exist!
Or rather, the Exploding Water Colliding Wave and the Great Exploding Water Colliding Wave are essentially the same technique. The difference lies in the amount of chakra output and whether the user can control and handle such an enormous amount of chakra.
In the original work, only one person ever performed the Great Exploding Water Colliding Wave—Kisame Hoshigaki!
When Kisame fused with Samehada after absorbing Killer Bee's chakra, his chakra levels skyrocketed. To create a suitable water environment for his Water Release techniques, he generated an entire "ocean"!
The jutsu he used was simply an enhanced version of the Exploding Water Colliding Wave.
Based on comparisons with the mountain landscapes depicted in the manga, Kisame's "ocean" had a radius of about ten kilometers. Assuming an average depth of one meter, the total water volume would be 31.4 billion cubic meters!
This far surpassed the water volume of Tide Listening Lake!
Haruto Saito already knew the Exploding Water Colliding Wave.
He could also perform the Great Exploding Water Colliding Wave!
The only problem was—he didn't have enough chakra!
That's where Tsunade came in.
Tsunade naturally possessed a vast chakra reserve. As a top-tier medical ninja, she could directly transfer her chakra to others for immediate use.
With her help, Haruto Saito would be able to perform the Great Exploding Water Colliding Wave!
When cast, the initial impact of the Great Exploding Water Colliding Wave would be concentrated on a single point before spreading out according to the terrain.
In this case, due to geographical constraints, the water wouldn't be able to spread out in a perfect ten-kilometer radius. The area wasn't flat ground—it was a mountain valley. As a result, the spread would be limited, meaning the depth of the water would increase.
If such an enormous amount of water were to rush down a relatively narrow river channel, the force of impact would be even greater due to the restricted spread!
"Lady Tsunade, all you need to do is lend me your chakra when the time comes. Leave everything else to me!" Haruto Saito said.
Tsunade tilted her head, paused for a moment, then looked away and hummed in acknowledgment.
At this point, there was no reason to doubt anymore.
Regardless of success or failure, today's retreat wouldn't be too difficult for the team. The only concern was that if Haruto Saito failed, he would lose hundreds of extremely expensive sealing explosive tags and tens of thousands of regular explosive tags.
Conservatively estimated, the loss would be around five hundred million ryo!
A short while later—
East of Tide Listening Lake, in a small grove—
"Lord Orochimaru, are you ready?" Haruto Saito asked.
Orochimaru nodded and exchanged a glance with Jiraiya.
"Alright then, let's begin. Lord Jiraiya, Lady Tsunade, you will be in charge of vigilance. Lord Orochimaru, you will set up the barrier. Ryuya and I will handle the digging."
Work commenced!
Orochimaru had already laid the foundation for the barrier earlier when Haruto Saito and the others had been scouting the lake. With Jiraiya's assistance, he now activated a barrier with a hundred-meter radius.
This was a secret technique!
The function of the barrier was simple—to block both aura and sound.
It was already certain that the sensory-type ninja at the Mist Ninja encampment wouldn't be able to detect any chakra fluctuations here due to the terrain. The enemy camp was halfway up the mountain, while this location was a few kilometers further into the mountain range, separated by a large rocky outcrop. Since sensory abilities function through waves that spread out in straight lines, they wouldn't be able to penetrate several kilometers of solid rock!
No sensory ability could pass through that much dense rock—this was beyond question.
However, chakra signatures could still disperse in the air!
And the ninjutsu that Haruto Saito and Hattori Ryuya were about to use would generate an incredibly strong chakra presence. If the energy fluctuations spread too far, there was a chance of being detected. To eliminate that risk, Orochimaru was tasked with setting up the barrier!
"One Hundred and Twenty-Eight Spiral Piercing Stabs!"
"One Hundred and Twenty-Eight Spiral Piercing Stabs!"
Haruto Saito and Hattori Ryuya simultaneously activated their jutsu at different locations!
An S-rank forbidden technique!
This was Hattori Ryuya's unique ability. Back when Haruto Saito had tried to eliminate him using the Mutual Multiplication Explosive Tags, Ryuya had escaped at the last second by instantly burrowing thirty meters underground—thanks to this very technique!
Two figures spun downward in a spiral, drilling into the rocky ground, instantly reaching over ten meters deep!
The terrifying chakra surges from both of them were completely contained within the barrier, preventing any leakage.
Moments later, the two emerged from the ground, moved to a new location, and drilled again!
Though this was a rocky mountain, the summit wasn't entirely solid rock. The topsoil was still thick—after all, this was a mountain peak, not the mountainside. If it were all bare rock, no vegetation could grow here.
Drilling ten meters deep was enough!
They could go deeper if necessary—but there was no need.
If they dug twenty meters or more, the explosive tags buried underground might be too deep to detonate effectively.
An hour later—
Hattori Ryuya had sustained significant internal injuries and had nearly exhausted his chakra. Tsunade treated him briefly before he continued. Meanwhile, Haruto Saito remained energetic and unscathed!
The two regrouped, taking another look at the explosion engineering plans prepared by the "geologists" to confirm the next steps.
