Each time the Super Strength Fist is used, the tiniest nerves and blood vessels in the arm suffer microscopic damage, making it impossible to use the Super Strength Fist for extended periods.
Uchiha Nagi was very satisfied with the Super Strength Fist, which he could only use less than ten times. When he copied Akaza's martial arts body techniques, he knew that some extremely powerful body techniques could only be fully utilized by a relatively strong physique.
For example, the Eight Gates Release Formation requires an incredibly high physique to open the seventh gate, so Uchiha Nagi had long anticipated that the Super Strength Fist would also demand a lot from the body.
Moreover, this technique doesn't make one strong just by opening it; rather, it makes an already strong person even stronger, just like how Might Dai opened the Gate of Death but still let a few of the Seven Ninja Swordsmen escape.
Furthermore, Ninja are a bunch of cunning individuals. If someone sees you activate a forbidden Ninjutsu, they'll immediately run away, and then stealthily return once your time limit is up. Therefore, this technique can only be used when teammates are protecting you, or not at all. If you do use it, you must completely annihilate the enemy.
As for why Tsunade, despite inheriting the First Hokage's powerful physique, didn't learn the Eight Gates Release Formation? Nonsense, what woman would learn such a masochistic training method? Being a slacker is so much more comfortable, eating, drinking, and traveling every day is much better.
Uchiha Nagi, too, wouldn't possibly learn the Eight Gates Release Formation, because he couldn't abandon Ninjutsu, Genjutsu, and Kenjutsu to specialize solely in the Eight Gates Release Formation.
So Uchiha Nagi only learned enough to open the first two or three gates; that was sufficient.
"Sigh~ Regardless, training to strengthen the body still cannot stop." Uchiha Nagi sighed. Such a powerful ultimate move as the Super Strength Fist couldn't be neglected.
Moreover, a strengthened body also benefits Kenjutsu, making its power even greater.

"Are you sure? The target is the long-missing Konoha rogue Ninja, Uchiha Nagi?"
"Confirmed. The Anbu operative, who went to find Shizune, confirmed that the person who fought Lady Tsunade was indeed from the Uchiha Clan, an Uchiha Clan member who had activated the Mangekyo."
In a teahouse, two people dressed as civilians were secretly whispering to each other. These were members of Root. After Tsunade was attacked, Shizune left Konoha's unique distress signal.
As Konoha's princess, Tsunade naturally had the privilege of having a lurking Anbu come to her rescue, but unexpectedly, the battle was already over before help arrived.
Later, when the Anbu arrived and met with Shizune, they naturally learned the situation. And the Anbu had long been infiltrated by Danzo, so someone here was relaying information to the Root members.
"Good, I will immediately transmit this information back to Lord Danzo. Lord Danzo has been searching for this Uchiha Nagi for a long time, constantly restless."
"Good, then you go quickly. I will find a way to keep an eye on him—" After speaking, the two nodded and walked away as if nothing had happened. In a neutral small country like the Land of Hot Water, necessary disguises were still required.
Uchiha Nagi frowned, feeling somewhat uncomfortable, yet he didn't know why.
After awakening his Mangekyo, Uchiha Nagi's senses were extremely keen. He could even detect someone staring at his back, and after special training with Stone Pillar, his senses became even stronger.
However, these past two days, he always felt a bit uneasy, but upon careful thought or after setting traps, he couldn't find any enemy.
"Could it be? Up in the sky—" Uchiha Nagi looked up, activating his three-tomoe Sharingan. He carefully observed from a distance and indeed saw an eagle tailing him in the sky, several kilometers away.
Uchiha Nagi: "..."
It's definitely confirmed. That thing must have been trained by Ninja. It might not be a very powerful summoning beast, lacking special abilities.
The reason he didn't feel a prickling sensation like a thorn in his back was because the other party was just an ordinary animal, an ordinary eagle.
The eagle had no Chakra, which was to avoid being detected by sensor Ninja. Sensor Ninja basically find it very difficult to detect small animals without Chakra.
But the eagle's eyesight was excellent, able to see clearly from ten kilometers away.
"This is troublesome. I can't fly..."
Uchiha Nagi looked at the eagle in the sky with a headache. It was so far away, several kilometers high; his Sharingan Genjutsu wouldn't be able to hit it... He thought for a moment, since it wasn't a summoning beast but an ordinary eagle, its intelligence wouldn't be particularly high, so he could use some tricks to deceive it. While passing through a forest, he used a Shadow Clone, hid his main body, and after leaving the forest, the Shadow Clone led the eagle far away in another direction.
Uchiha Nagi's main body, meanwhile, rested well in the forest, waiting until nightfall to set out. Although traveling at night wasn't ideal, his Sharingan's vision was clear enough.
This time, it went smoothly. Without the eagle's surveillance from above, he successfully traveled all night and reached the coast.
Arriving at a port, he looked at the surrounding merchant ships and casually picked a relatively large one. Merchant ships with cargo usually have many people and goods, and with more people, it's easier to blend in and act unnoticed.
He quietly snuck into the captain's cabin of the merchant ship. The drowsy captain, just opening his eyes, saw a pair of red eyes... "I am your distant relative. I'll be in your captain's cabin these next few days. Remember not to tell anyone about me—" Uchiha Nagi said.
"Alright—" the captain responded drowsily.
"Good, then. I'll sleep in the bed, you sleep on the floor..."
"Yes..." At sea, the captain is the most powerful person on the ship, and no one dares to enter the captain's cabin without permission. Uchiha Nagi could safely stay inside until they reached the Land of Water.
As for how to avoid the Land of Water Ninja's inspections upon arrival? Couldn't he just disembark early?
The coastline is so long, and the Land of Water doesn't have that many Ninja patrolling.
Ninja's abilities allow them to go into the sea, walk on water, and climb mountains; they simply can't be stopped... "Damn it, they found us, it's a Shadow Clone." A masked Ninja, leading four others, a total of five people in a small squad.
This squad was a pursuit squad, specializing in sensing, reconnaissance, and speed.
For Uchiha Nagi, who didn't have the Byakugan and wasn't a sensory Ninja, unable to sense enemies several kilometers away, they were actually very safe.
As long as they firmly kept Uchiha Nagi on a leash like flying a kite—chasing if he ran, fleeing if he turned back—and waited for the main force to arrive, they would be fine.
Who would have thought that even an eagle without Chakra would be detected by Uchiha Nagi.
After pursuing for a day and a night, Uchiha Nagi's Shadow Clone dissipated due to Chakra exhaustion, and only then did they realize they had been fooled.
The cat-masked leader reluctantly announced, "Mission failed. We've lost the target's trail. Report to Lord Danzo..."
"The target has likely gone to sea..."
