Ninja World: I, Kisame Hoshigaki, am no longer human!

It can be said that at the age of 12, Kisame's starting point was higher than Nagato's and Naruto's.

Therefore, he decided to learn from their experiences and lessons, and adopt a scientific training method to fully unleash his potential.

That method is fitness.

Fitness is a relatively common form of training in the world of Naruto.

Among them, the Land of Lightning has the strongest fitness culture, with muscular, dark-skinned men everywhere. The Raikage is a fitness fanatic, even having barbells and dumbbells in his office.

Konoha Village also has its share of avid fitness enthusiasts. Might Guy and his son would often run hundreds of laps around the village, followed by thousands of push-ups and leg kicks, pushing themselves to the limit.

Kirigakure also has a fairly large gym, where many ninjas exercise regularly.

In his past life, Kisame was not only a practitioner of unrestricted street fighting, but also a fitness enthusiast who had been working out for over ten years and benefited greatly from it. Despite being almost thirty, he looked like a high school student, appearing remarkably young.

There's another reason why he chose to work out and build muscle.

After absorbing the Raito Kiba, Kiba's body's capacity was nearing its limit. He realized that if he wanted to absorb more ninja swords, he needed to develop a stronger physique.

Therefore, fitness is imperative.

Kisame was swift and decisive; once he had an idea, he immediately began to act.

Early in the morning, he arrived at the gym in the center of the village, registered at the front desk, and became a long-term member.

Upon entering the equipment area, a strong smell of hormones hit you. To put it bluntly, it was the smell of sweat.

At first glance, this gym is not luxurious, and is even somewhat dilapidated: mottled and dirty walls, dimly lit chandeliers, and old and rusty equipment; the decor is quite rough.

The weather in Wuyin is very humid, so the gym equipment is easily corroded. It made a cracking sound as soon as you picked it up, but fortunately, the variety was quite complete and enough to use.

Kisame ate ten eggs when he woke up in the morning, and after arriving at the gym, he quickly began to work out.

He first walked to the dumbbell rack, tried it out for a bit, then picked up a pair of 50kg dumbbells, lay down on the dumbbell bench, and skillfully completed several sets of bench presses and flyes.

boom!

After completing the last movement, Kisame threw the dumbbells on the ground, straightened up, and frowned slightly.

He could feel the blood rushing to his chest muscles, a tearing sensation, but it wasn't very intense.

Keep in mind that a dumbbell bench press of 50kg was already a gym pro level in my previous life, enough to compete in fitness competitions.

But for 12-year-old Kisame, it was too easy and didn't have much of a training effect.

Sure enough, he was still too reliant on his past experience and didn't let go.

In the previous life, the total number of cells in an adult's body was between 30 trillion and 40 trillion. In the Naruto world, however, an ordinary person has 130 trillion cells, which is three to four times that of the previous life.

As for monsters like Kisame, they might have even more cells in their bodies.

Moreover, given his body's recovery ability, he probably doesn't need to worry about overworking himself and causing problems like rhabdomyolysis.

Therefore, Kisame revised his fitness strategy:

Train until you drop dead!

With this philosophy in mind, he significantly increased the weight and began his second round of training.

In the huge gym, Kisame was sweating profusely all by himself, engaging in intense battles with various fitness equipment.

The morning flew by.

"call!"

Kisame let out a long sigh of relief, left the gym covered in sweat, and returned home.

His lunch consisted of several kilograms of beef, a bowl of milk, and a large amount of vegetables.

Although Kisame's house was dilapidated, his father had left him some inheritance, and he had also saved some money from missions during his two years as a genin, so he didn't have to worry about food for the time being.

After finishing his meal, Kisame squinted and took a half-hour nap.

In the afternoon, instead of going to the gym, he went to the grove by the river to practice taijutsu and ninjutsu.

In this world, ninja taijutsu is divided into many styles, such as "Steel Fist Style," "Gentle Fist Style," and "Ninja Taijutsu," but Kisame's taijutsu does not belong to any of these.

He decided to integrate the skills he learned from practicing unrestricted street fighting in his previous life into his own physical techniques, gradually forming a complete system.

It's called "Unrestricted Physical Techniques".

What is meant by unrestricted physical combat?

For example, you challenge an enemy to a duel. First, you put laxatives in their food to weaken them. Then, in the middle of the night, you go to their door and make a lot of noise to keep them awake. Finally, the next day, you arrive at the scene and drive a dump truck out from the side and kill them.

This is unrestricted physical combat.

Unrestricted physical techniques are entirely based on actual combat. When fighting an enemy, the first thing that comes to mind is "sneak attack, ambush, and deception"—these despicable and shameless acts are precisely the best ways to succeed.

Kisame's previous techniques, such as throwing lime, groin kicks, and the Mad Dog Style fighting style, all fall under the category of unrestricted physical techniques.

He realized that in this treacherous and dangerous ninja world, unrestricted taijutsu (physical techniques) definitely had great potential.

So Kisame wandered around the forest, found a tree trunk as thick as a bucket and taller than a person, and fixed it to the ground to make a wooden dummy.

Then, he stared intently at the wooden dummy, imagining it as the enemy who had killed his entire family and whom he could not bear to part with. Soon, he was filled with rage and gritted his teeth.

His face was flushed, his anger, hatred, and murderous intent intertwined like a volcano about to erupt.

"Boiled!"

Finally, Kisame cursed and, like a mad dog, launched a fierce and relentless attack on the wooden dummy.

Gouging eyes, picking noses, kicking groin, kneeing, slamming...

They used every kind of vicious and ruthless move imaginable.

This kind of physical training allows Kisame to instantly enter a "mad dog" state when fighting enemies, releasing terrifying killing intent and thus gaining the upper hand.

Click!

During the intense training, the wooden dummy finally gave way and was broken in two by Kisame.

Kisame clapped his hands contentedly. That concluded today's taijutsu training. Now it was time to practice ninjutsu.

Water Release is Kisame's absolute strength.

Looking at the entire history of the Naruto world, his talent in Water Release ninjutsu is also top-notch, with only a handful of people like Tobirama Senju, Hanzo, and Gengetsu Hozuki being able to compare.

Swish swish.

By the river, Kisame swiftly formed several hand seals, summoning a semi-transparent blue shark.

Water Release: Water Shark Bullet Technique.

This is Kisame's signature ninjutsu, using chakra to condense into shark-shaped water bullets to attack enemies. Furthermore, he can also envelop himself in water bullets and glide through the air.

Kisame's heart skipped a beat. He burrowed into the shark-shaped water bullet and soared into the air. After circling for a while, he plunged into the river like a precision-guided missile, creating a huge splash.

Once back in the water, Kisame felt incredibly comfortable, as if he were home.

After swimming for a while and confirming that no one was around, he dived into the water, and the shark tail lightning whip popped out from behind him with a "whoosh".

sizzle.

Lightning flashed beneath the water's surface as Kisame swung its tail, moving like a ferocious humanoid shark, its speed as fast as lightning, free and unrestrained.

In the water, his combat power is multiplied several times, and he can easily deal with or escape even when surrounded by a large number of enemies.

This made Kisame realize that he must fight in an environment that is favorable to him.

If there is no favorable environment, use water escape to create one.

The ninjutsu practice continued until evening.

Besides taijutsu and ninjutsu, Kisame was also very interested in genjutsu, since it should be very useful for surprise attacks. Unfortunately, he really didn't have any talent in this area.

Therefore, we had no choice but to give up.

Night falls, and the night sky is dotted with stars.

After getting out of the water, Kisame wrung out his clothes and went home.

He ate twenty egg whites in one go, along with some carbohydrates, and then, dragging his tired body, went to bed early to rest.

Early the next morning.

Kisame was surprised to find that the soreness in his body had completely disappeared as soon as he got up.

It's important to know that the recovery period for different muscle groups in the human body is 24 to 48 hours for small muscle groups and 72 hours for large muscle groups, but Kisame recovered to his best condition overnight.

He trained so hard yesterday that his pectoral muscles no longer hurt at all.

Kisame went to the mirror and, sure enough, found that his two pectoral muscles had visibly grown larger.

This kind of talent is simply one in a million—a fitness prodigy.

So from that day on, every time Kisame went to the gym, he would work out every muscle group in his body, not even sparing his biceps.

His training intensity increased day by day, and soon he left everyone else in the gym far behind.

The gym was filled with deep growls and the clanging of metal equipment.

A group of Hidden Mist ninja gathered together, eyeing Kisame who was exercising alone in a corner, and whispering among themselves.

8. Getting caught in the rain is bad for your health.

"That brat is Kisame Hoshigaki? He's a tough character."

"He's practically a monster."

Since using his "Mad Dog Style" taijutsu to fight multiple opponents in front of the Mizukage Building, Kisame has gained a small reputation in the village these days, and is known as "Mad Dog Kisame".

Kisame ignored everyone else in the gym and focused entirely on his workout.

At this moment, he was doing supine leg raises with equipment, and had reached the edge of exhaustion. His face was flushed, and he was in severe facial compensation, wearing a mask of pain.

This is the last set of exercises; just three more to complete today's training.

"Yebadi, Levibebe!"

Kisame let out a deep roar to bolster his courage. The veins in his legs bulged, and with all the strength in his lower body, he finally pushed forward.

Three, two, one.
