### Chapter 8: You Shouldn't Have Done That to Rin's Photo
Time flew by, and soon the last day arrived.
After the Missing-nin Kyouko fiddled around for a while, he sealed some brown liquid medicine into transparent bags.
Kyouko looked at these bags, feeling they inexplicably resembled the Traditional Chinese Medicine from his previous life...
"After you take these, they can strengthen your physical body, which will then drive your chakra volume up. Conservatively, it can increase your current amount by double."
The Missing-nin Kyouko said.
With a low base mana pool, increasing it was simple.
"Double? Not bad."
Kyouko was even more satisfied with the effect.
This way, although his rank was only Genin, his strength would be considered strong even among Chunin.
As long as he had enough chakra, screw technique—he could just brute force everything.
For example, Six Paths Naruto was purely a display of stats: Sage body + Tailed Beast chakra + Sage Mode enhancing the body + Six Paths Power enhancing the body.
With this set, all he needed to do was spam Rasengans.
"I remember Takigakure has a forbidden drug called 'Hero Water'."
Kyouko said.
In the anime's Takigakure arc, a forbidden drug called "Hero Water" appeared, which could increase chakra tenfold upon drinking!
It's just that the user wouldn't live long afterwards.
"It is good; drinking a small amount can save your life. But Takigakure also has the Seven-Tails guarding it."
The Missing-nin Kyouko shook his head.
Did Kyouko think he hadn't thought of that?
It was purely a matter of insufficient strength.
Even with "Kage" level strength, one wouldn't dare say they had a sure chance against a Tailed Beast.
A casual Tailed Beast Bomb could level a mountain, which is why Tailed Beasts were treated as weapons of war by various nations.
Hashirama Senju also believed that distributing Tailed Beasts to achieve a so-called balance of power would allow the nations to live in peace forever.
But just as the Qin Dynasty fell after the second generation, war erupted in the Ninja World immediately after Hashirama died.
"True."
Kyouko also felt he was being a bit impetuous.
As long as he had the Testament and continuously merged with his selves from other timelines, he could also become a stat monster.
"Bottoms up."
Kyouko used a kunai to slit open the sealed plastic bag and drank it all in one gulp.
Bitter!
That was Kyouko's first reaction.
Then came a splitting headache, as if his brain was about to explode.
Wait, the Missing-nin Kyouko said it would hurt, but he didn't say it would hurt this much!
Kyouko clutched his head and crouched down, enduring the pain.
"Your chakra volume is rising now. The headache is from your brain producing chakra."
The Missing-nin Kyouko said.
This forbidden drug utilized the principles of Yang Release chakra.
Through the reaction between certain herbs and the human body, a special chakra was produced, which then nourished the physical body.
As physical energy rose, the ninja's chakra volume would also increase.
Sure enough, after the initial pain passed, Kyouko could feel a warmth spreading through his limbs and bones.
It was like suddenly soaking in a hot spring after not bathing for ten days.
Once the drug's effects had mostly passed, Kyouko clenched his fist.
Brand new power!
Then Kyouko went to the courtyard, formed hand seals—still Dog, Horse, Bird.
"Wind Release: Great Breakthrough!"
A gale spewed from Kyouko's mouth, blowing the gravel on the ground and smashing against the courtyard wall with a bang, forcibly creating a hole.
The small pebbles turned into powder and scattered on the ground.
"As expected, increasing the chakra output increases the power."
Kyouko thought to himself.
It was like how a single Fire Release jutsu from Madara Uchiha required twenty Water Release ninja forming a squad to use Water Release together just to cancel it out.
After all, Madara Uchiha was someone who could fight Hashirama Senju. He even used the Nine-Tails as a summon and didn't absorb its chakra, fighting Hashirama entirely with his own chakra. His chakra volume couldn't be small.
"Hiss..."
Kyouko clutched his head.
A sudden burst of stinging pain had just flashed through.
This was the price of using the forbidden drug. Fortunately, it would resolve in three months.
"If I take this forbidden drug again in three months, will it still be effective?"
Kyouko asked.
"No effect."
The Missing-nin Kyouko shook his head.
Nothing is that good.
This forbidden drug only further stimulated the body's potential; the effect was best only the first time.
After that, it could be said to have no effect.
Otherwise, why would Orochimaru be so obsessed with Sasuke's body? Physical talent was simply too important.
"Is that all..."
Hearing this, Kyouko picked up a piece of rubble roughly the size of the hole and plugged the wall.
"Then next is practicing ninjutsu."
Kyouko planned to learn another Lightning Release jutsu.
Among the five basic nature transformations, Lightning Release arguably had the highest ceiling.
The reason was simple: later enemies like the Ten-Tails Jinchuriki, the Otsutsuki clan, and even various artificial humans mostly possessed the ability to absorb ninjutsu, unless one learned Senjutsu.
Otherwise, Earth Release, Wind Release, Water Release—they would all just be absorbed.
Even "Amaterasu," known as the strongest attack, suffered from being a single attribute and was easily countered.
But Lightning Release was different. Lightning Release could activate cells, enhancing taijutsu in all aspects and increasing basic stats.
This way, those abilities to absorb ninjutsu would be ineffective.
"I'll learn 'Lightning Release: Earth Flash' first."
Kyouko looked at the scroll in his hand that recorded several jutsu.
The Missing-nin Kyouko had dictated a total of two Lightning Release jutsu and three Fire Release jutsu.
Among them was "Lightning Release: Earth Flash."
This jutsu could release a cluster of irregular lightning bolts close to the ground.
The Battle of Kannabi Bridge would take place in a valley filled with forests.
Some places would be very narrow. Using this move there would leave the enemy with limited space to dodge, making it hard to avoid.
...
The next day.
Kyouko put on the new chainmail lining he bought, dressed in his outer clothes, shouldered his marching pack with all his tools organized, and headed to the meeting point.
"Obito is late again."
When Kyouko arrived, he heard Kakashi complaining about Obito.
"Probably helping an old lady somewhere again."
Genma Shiranui had a senbon in the corner of his mouth.
He knew a bit about Obito's nature; after all, they were classmates.
"Where is Kurenai?"
Kyouko came over and asked.
"Preparing up ahead."
Genma Shiranui pointed forward, where Kurenai Yuhi was busy checking the items to bring.
"Kyouko, Rin, please go find Obito."
Minato Namikaze said.
He didn't ask Kakashi because he was afraid the two would get into a conflict.
At this critical juncture, it was better for the team to be harmonious.
"Yes, Teacher Minato."
Rin Nohara nodded.
Kyouko naturally had no objections. He hadn't been to the Uchiha clan's residential area yet, so it was a chance to broaden his horizons.
He remembered that Obito once kissed a photo of Rin, and when Kakashi went to find him, he stumbled upon the scene.
He wondered what Obito was doing right now.
"Let's go, Rin."
Kyouko said.
"Mm."
Rin Nohara trotted to keep up with Kyouko.
Meanwhile, Obito was oblivious to the world.
He was going to the battlefield today, so he planned to relax a bit.
So he took out the Team Minato group photo, which included Rin Nohara, Kakashi, Minato Namikaze, and himself.
