[The battle erupts instantly.]
[The piranhas show no fear of your size, which is twice as large as theirs. Dozens of them charge at you frantically together.]
[You show no fear, opening your large mouth full of sharp teeth and charging forward as well.]
[You bite one piranha. Your sharp, saw-like teeth directly tear the piranha in half. But the piranha school also leaves numerous wounds on your body.]
[You realize you cannot continue fighting like this. Otherwise, you might die from excessive blood loss.]
[You start to maneuver, using aquatic plants and reefs as cover, evading the piranhas' attacks, and then seizing opportunities to ambush.]
[This tactic is very successful. After just a few rounds, the number of piranhas begins to decrease sharply.]
[But piranhas are reckless fish that do not know retreat. They show no intention of fleeing due to their reduced numbers, fighting with you until they all become food for your stomach.]
'Brutal, but also single-minded.'
Takumi couldn't help but complain, but then became excited immediately.
Having eaten so many piranhas, the boost in attack power must be significant.
The Devour talent exactly reflects the characteristics of devoured targets onto oneself.
What are the characteristics of piranhas?
Of course, their extreme aggression!
[After eating a school of piranhas, you find your body size has become larger, your teeth have become sharper, and their number has increased.]
[As your body size increases, you find the area you can move in is gradually shrinking.]
[By chance, a human corpse floating down the river makes you realize how big you have become.]
'Already the length of an adult human height in such a short time?'
Takumi was very surprised.
It didn't seem like many days had passed.
Apart from the fast growth rate of fish themselves, it was more due to the Devour talent.
[The river can no longer let you swim freely. You need to find a larger world.]
[Following the river downstream, crossing who knows how far, you finally arrive at an incredibly vast expanse.]
[You have reached the sea.]
[The seawater is somewhat difficult for you to adapt to, but after you eat some sea fish, this discomfort disappears without a trace.]
[The incredibly rich food reserves in the sea become your paradise for rampaging.]
[In the shallow sea where no one can restrict you, you soon attain a body length exceeding three meters.]
"This is making me a bit hungry."
Takumi swallowed his saliva. 'Speaking of which, how long has it been since I ate sashimi? I must try it when I have the chance.'
Thinking of the deliciousness of sashimi, Takumi's saliva ultimately couldn't be held back, flowing down unbecomingly.
[As you gradually move away from the mainland, entering deep-sea regions.]
[Threatening marine creatures also begin to appear one by one.]
[Sharks with sharp teeth like yours, highly toxic floating jellyfish, giant squids, and even sperm whales that hunt giant squids, etc.]
[By comparison, you realize your body size does not hold an advantage.]
[You avoid dangerous enemies, continuing to endure and develop discreetly until you can become the strongest fish.]
[As you continuously eat, your body size also increases rapidly.]
[Unconsciously, you reach a length of ten meters.]
[There is still a gap compared to sperm whales, but it's almost comparable to orcas that can hunt great white sharks.]
'This growth speed is really fast. Just by eating, you can keep improving.'
'If training could be this simple, that would be great."
Takumi felt somewhat envious.
Although he hadn't trained seriously in the conventional sense, it didn't stop him from feeling envious.
Who wouldn't want to become stronger just by eating?
[You feel you no longer need to endure. You begin to hunt frantically.]
[Whitetip shark, devoured! Mako shark, devoured! Bull shark, devoured! Great white shark, all devoured!]
[All large fish swimming before you that cannot exceed your size become your hunting targets.]
[Blood attracts more hungry sharks. This area of the sea gradually becomes soaked in blood, turning into a crimson red, but soon returns to its original clarity under the washing and decomposition of seawater.]
"This is truly the purest example of the strong preying on the weak."
Takumi sighed with emotion.
The laws of nature are always so cruel.
But no one can criticize it.
It's for survival.
Unlike humans, who kill merely for pleasure, the Takumi in the simulation did not waste any killed targets… he ate them all.
[Your body size also becomes larger and larger. Finally, when a sperm whale appears before you, you realize you have already become larger than the sperm whale.]
[In the ocean, ordinary fish can no longer harm you.]
[But this is not an ordinary world. Here there are Summoned Beast, creatures in form but capable of using Chakra.]
[You encounter a shark that is not large in size but can use Ninjutsu.]
[It can manipulate ocean currents to attack you, preventing you from easily touching it.]
[Finally, you use a strategy, playing dead. As it carelessly approaches, you swallow it in one gulp.]
[Afterwards, you feel you possess a bit of Chakra.]
[Overjoyed, the greedy sense of hunger makes you come up with an astonishing plan.]
'Having Chakra means a qualitative improvement in combat power.'
'Originally, the body size was already sufficiently huge. Now, being able to use Chakra to fight, I'm completely invincible in the sea.'
Takumi nodded in satisfaction.
Although he still didn't know what the so-called astonishing plan was, it seemed now things were developing in a good direction.
The final outcome was still hard to predict, but it certainly wouldn't be dying silently.
[To execute that astonishing plan, you begin searching for marine creatures that are Summoned Beasts, while also figuring out how to refine Chakra yourself.]
[Through continuous figuring out, you understand the method of Chakra Refinement. Your massive body can easily provide large amounts of Chakra.]
[During this period, you are also constantly eating to fill your insatiable appetite.]
[Thus, to execute the plan, you come from the deep sea to the coastal waters and station yourself in the sea not far from Kirigakure.]
'Holy crap! Could the astonishing plan be...?'
Takumi's eyes widened in surprise.
Then his eyes revealed excited glee.
'If the plan succeeds, then I'll truly be invincible!'
[A massive tail slaps down, combined with Chakra, stirring up waves over a hundred meters high.]
[The giant waves rush towards Kirigakure, the furious tides destroying a large number of structures.]
[Countless people suffer, submerged by the huge waves.]
[Kirigakure's Shinobi immediately mobilize and soon discover your presence.]
[You show no fear, still slapping out enormous waves, and secretly controlling currents within them, pulling Kirigakure's Shinobi underwater beneath the surface and devouring them.]
[Kirigakure's Shinobi suffer heavy losses. The Yondaime Mizukage, Yagura, finally takes action.]
'The target has appeared, but not completely yet.'
Takumi's eyes closely watched the simulation screen.
Next would be the most crucial battle.
Whether the plan succeeds or not depends on this fight.
[Facing your massive size, Yagura immediately borrows the power of the Sanbi, Isobu.]
[However, Yagura, who only undergoes partial Biju Transformation, cannot harm you. You have the entire sea as your backing and do not fear any of his Ninjutsu.]
[Even the extremely powerful Bijudama, you can avoid by diving into the sea bottom in advance.]
[Having no other choice, Yagura finally undergoes complete Biju Transformation, releasing Sanbi.]
[The battle between two aquatic giants is about to begin.]
'The real target has appeared!'
Takumi couldn't help but rub his hands, easing the nervous excitement in his heart.
[Sanbi lets out a roar, simultaneously releasing a powerful Bijudama.]
[You dive into the deep sea, dodging the attack while launching a surprise attack from the sea bottom.]
[Ocean currents under your control are like water snakes, entangling Sanbi and dragging it into the deep sea.]
[Then you open your bloody maw, ferociously biting off one of Sanbi's tails and devouring it.]
[The Sanbi's Chakra wants to run wild, but it is quickly digested by you, becoming your power.]
