Meanwhile, in the Senju clan compound…
Crackle! Crackle! Boom!
The sky darkened with black storm clouds, casting a shadow over a large portion of the Senju clan grounds, centering the private training ground of Senju Tobirama.
Thunder flashed from the storm clouds and branched off, creating a rather intimidating visual spectacle.
All the ninjas and civilians residing in the Senju clan compound and the nearby areas couldn't help but crack their necks up to the sky.
Most of them, who didn't understand what was going on, had one question in their minds: The day was beautiful, and the sky was clear blue just a few moments ago. So, where did this random thunder cloud come from all of a sudden?
Some were puzzled. Others were terrified, which was natural since it felt like a stray thunderbolt might just come down and strike them.
However, the powerful ninjas with great chakra sensitivity, such as the Senju clan elders and Elite Jonins, could clearly sense a large amount of water and lightning chakra infused within the storm cloud.
Those elemental chakras, controlled by the caster, were forcing storm clouds to collide and create enough friction to generate natural thunder, further increasing the frequency and power of the thunder.
Those powerful Senju clan ninjas, nearby onlookers with immense chakra sensing capabilities, the Hyuga with Byakugan, the Uchiha clan ninjas with mature three-tomoe Sharingan, and the Uzumaki clan with almost unscientific innate sensing capabilities could all feel the power of the technique that was about to be unleashed.
Fortunately, whatever the Jutsu was, it did not lock onto them. Otherwise…
Hissss…
Just thinking about it sent chills down their spines.
An S-rank technique. It was definitely an S-rank technique.
And the one who was about to unleash the Jutsu seemed to have enough chakra capacity and quality to release the Jutsu with such power that even Kage-level ninjas would have to run for their lives.
At least, that was the truth for the ninjas who had just stepped into the Kage-level and had no suitable wide-area defensive or offensive techniques.
Of course, no Kage-level ninja would just sit back and let their enemies unleash such a Jutsu. Most S-rank elemental Ninjutsu with wide-area annihilation capabilities needed an enormous amount of chakra to charge and cast.
In other words, even with several hand seals, the ninja might need several seconds to focus and cast the S-rank elemental Ninjutsu.
Unless the caster reached the strength of a peak Kage-level ninja, mastered the technique perfectly, developed their elemental affinities to LV7, or had a special physique or circumstances, casting an S-rank wide-area annihilation-class elemental Ninjutsu within one to three seconds is almost impossible.
But at the same time, ninjas who were capable of unleashing such a frightening S-rank Ninjutsu would surely take several countermeasures to make sure they could unleash techniques without interruption.
Then, it would become a cat-and-mouse game. Either the Kage-level ninja killed the ninja unleashing this S-rank Jutsu first, or the ninja would successfully release the Jutsu and severely injure or kill the Kage-level Shinobi.
At the residential house of Seimei and Tobirama, Uzumaki Mito and Senju Hashirama were also watching the dark thundering clouds through the window of their room.
"The chakra concentration is highest around one of the private training grounds of Tobirama. And I can sense the chakra signature of Seimei and Tobirama as well."
Hashirama discreetly stored his gambling cards and props in his secret pouch as he looked at the sky.
He had an amused smile and said with some exasperation, "Haah! Those two are at it again. And this time, they are planning to destroy an entire training ground in one go."
"Didn't they say they would just have a light sparring match? How did it escalate to a mini natural disaster?"
Mito stood beside him. She had already activated her Mind's Eye of Kagura and clearly sensed and saw Seimei and Tobirama face off.
She smiled gently and said, "Indeed, it's them."
"However…"
Mito glanced sideways at her husband and said with a cool voice, "You are the last person who should be talking about causing natural disasters."
"Compared to your almost 3-4 kilometer-tall Wood Release Ninjutsu empowered by the Sage chakra, this is still nothing."
"Seimei's technique would just affect the training ground. But you…Your True Several Thousand Hands almost caused a severe earthquake in Konoha."
"If not for the Earth Release specialists of the clan joining hands to neutralize the shift in tectonic plates, the whole Konoha would have collapsed."
Mito turned her head toward Hashirama and looked at him with a piercing gaze, which almost made Hashirama shrink his neck.
Mito continued, "You said you were going out to protect Konoha, but you almost destroyed it with your own hands."
"Or should I say several thousand hands?"
"If you weren't so injured at that time and your vitality wasn't that frail after the fight, I would have shown you what several thousand beatings of Adamantine Sealing Chains felt like."
Hearing his glorious deed and the talk about the chains of love, Hashirama broke out in a cold sweat. Damn, I got carried away at that time.
Hashirama racked his brain and tried to defend himself.
"Honey, you can't blame me alone for that."
"If not for Madara bringing the Nine-tails, covering it with Susanoo—Majestic Attire, and throwing tailed beast bombs here and there, would I have resorted to taking such extreme measures?"
"It was just that, while I was attacking the Nine-tails covered in Susanoo armor, I got a little carried away, and most of my wood constructs' thousands of punches end up hitting the earth hard."
"Hmph!" Mito snorted, but she dropped the topic.
She looked toward the training ground where Tobirama and Seimei were fighting with a worried expression.
"Let's hope they don't go too far, or I will need to patch up Seimei once again."
Fortunately, Seimei's innate vitality was immense, far surpassing all pure-blooded Senju and Uzumaki ninjas of his age. No matter how severe his injuries were, even if you beat Seimei to half death, he would fully heal with a bit of treatment.
Mito had tested it several times. After a couple of days of the treatment, all internal injuries, hidden wounds, and broken bones would heal.
Injuries that would make most ninjas cripple or force them to stay bedridden for a month to recover completely after treatment and potion administration were nothing but a scratch to Seimei.
No matter how deep the wound was, after treatment, not even a scar would remain in his body. He wouldn't even feel post-treatment lethargy and wake up as fresh as a lettuce the very next day and start jumping around with a body full of energy.
That was exactly why Mito wasn't worried too much about Seimei breaking several bones or losing his skin.
If that were not the case and Seimei were a normal Senju child, she would have stormed off by now and dragged Seimei back home while pulling his ears hard.
Thinking this far, Uzumaki Mito sighed.
"Whatever, let's wait for them. Once they have their fill, those two will come back."
"I will check the kitchen and decide what to make for lunch."
With that, Uzumaki Mito turned around and walked away.
When Hashirama heard about food, he immediately threw his worries away and joined Mito, walking by her side.
He laughed and said, "Hehe, let those two father and son fool around."
"But what are you planning to make, though? I am telling you, I won't touch vegetables today. I almost feel like vomiting the moment I see them."
Mito pursed her lips to suppress a chuckle.
The thunder in the artificially created storm clouds above roared even louder, frightening the kids and many ninjas, who were worried that the technique was going out of control.
But that had nothing to do with Mito or Hashirama.
Because they knew that Seimei would never try something like a large-scale Jutsu that he couldn't control, at least not while staying inside Konoha.
