Secret Medicine

Nighttime, third training ground.

boom.

With a muffled thud, Sasuke fell heavily from the tree trunk once again.

This was Sasuke's umpteenth failure; he was covered in mud, and his elbows and knees were covered in scrapes.

That's about it for today.

Naruto walked over from a distance, carrying three large bottles filled with amber-colored liquid.

"Too much of a good thing is bad. Your body has reached its limit. Drink this."

Naruto handed over the bottle, saying mysteriously, "This is my secret medicine that I don't pass on to others."

Secret medicine?

Sasuke was taken aback, as if the long-standing question in his heart had been answered.

No wonder he improved so quickly; it turns out he was using drugs to help him!

He took a bottle, unscrewed the cap, and a refreshing aroma of tea wafted out.

Sasuke frowned slightly.

black tea?

With some skepticism, he took a small sip.

The next second, Sasuke's brows relaxed.

As the cool liquid went down, an unprecedented tranquility instantly soothed his tense nerves.

Ever since the night of the massacre, Sasuke's mind has been filled with blood and screams.

He hadn't experienced this kind of mental tranquility in a long time.

Not only that, but even the muscle soreness from the training has subsided considerably.

Moreover, Sasuke vaguely sensed a slight, almost imperceptible increase in his chakra.

Sasuke was greatly shocked.

Because Naruto's chakra reserves are so large, he has never felt any increase in chakra reserves resulting from an increase in mental strength.

It's like adding a few drops of water to a pond—completely inconspicuous.

Although Sasuke is stronger and has more chakra than his peers, he is still at this level overall.

A subtle increase in chakra levels was clearly perceptible.

If it can be accumulated over a long period of time, there will definitely be a significant improvement.

Sasuke was even more certain in his heart that the reason why Naruto was able to improve so rapidly during this period of time was because of this.

In addition to his mastery of more advanced training methods.

The most important point is his secret medicine!

Drugs like these, which can bring about significant improvements, can increase chakra levels, restore physical strength, and calm the mind.

As long as the side effects aren't too severe, it's a priceless treasure.

Sasuke gripped the bottle tightly, his gaze towards Naruto becoming complex.

This guy actually gave me something so precious to drink so casually?

"Naruto, I hope you won't have too many regrets when you're surpassed."

As Sasuke imagined this scene, he couldn't help but smile. This advantage was on his side!

But then he realized that such a precious secret medicine must be extremely valuable.

Naruto is an orphan, and even with aid, he certainly couldn't afford to feed two people.

As a proud member of the Uchiha clan, he would never do something like taking something for free.

So Sasuke rubbed it against his chest for a while.

"then."

He tossed Naruto a wallet, which was quite bulging inside.

Naruto caught it and opened it. Good heavens, there were probably 30,000 taels of paper money.

"Give me one dose of that secret medicine every day from now on. Just tell me if you need money."

Sasuke stood with his hands in his pockets, looking like he had plenty of money and was quite arrogant.

Although his clan is gone, the legacy left by the Uchiha clan is enough for him to squander for several lifetimes.

Naruto took out the money from the wallet and threw it back.

"Deal made. The money inside is about a month's worth."

Naruto said.

In fact, although Naruto's life was not exactly wealthy, he was not short of money, and he didn't care about it.

In Naruto's opinion, enough money is enough.

His previous life appeared impoverished, more because he had money but nowhere to spend it, rather than because he lacked money.

This problem was only alleviated after he learned how to transform.

Naruto, who already had a deep understanding of Sasuke, accepted the money Sasuke gave him in order to alleviate Sasuke's psychological pressure.

To prevent him from becoming suspicious and even refusing out of pride.

This will actually slow down his improvement speed, and consequently slow down the feedback speed for himself.

Sasuke could only drink with a clear conscience once the transaction was confirmed.

Naruto really went to great lengths for Sasuke.

"Come back to me when you've mastered climbing trees, and I'll teach you a secret technique."

Naruto stopped Sasuke as he was about to climb the tree again.

"Secret technique?"

Sasuke became even more energized upon hearing this and decided to continue his training.

"Furthermore, in order to facilitate the absorption of the secret medicine and improve the efficiency of cultivation."

"I also have a strict set of daily routine requirements."

Naruto raised a finger and said seriously.

"Drink warm milk before bed, do 20 minutes of gymnastics, and sleep for eight hours."

"Huh? Are you kidding me!"

Sasuke said angrily.

He felt that Naruto was insulting his intelligence.

What kind of old lady's health regimen is this? I want to become stronger, not retire!

Don't rush to refuse.

Naruto interrupted him expressionlessly.

"Know that maintaining a good routine and getting enough sleep are great helpers in cultivation."

"You don't want your chakra refining efficiency to decrease due to lack of sleep, do you?"

Sasuke's face turned bright red, and after struggling for a long time, he finally managed to utter only one sentence:

"……hateful!"

Although it sounds ridiculous, Naruto's current strength is irrefutable proof.

And... what if...?

Besides, even if I didn't do it, how would Naruto know?

"If you don't meet my requirements for the next month..."

"Even if you learn how to climb trees, I won't teach you any secret techniques."

Naruto looked at the arrogant Sasuke and said slowly.

"asshole!!"

Sasuke was clearly dissatisfied.

"Don't even think about slacking off. While you're watching me, I'm watching you too."

"So, don't forget to buy milk later."

Naruto patted Sasuke on the shoulder, turned and left, concealing his merit and fame.

Only Sasuke remained standing there, still debating whether or not to go buy milk.

He now felt as if he had been completely manipulated by Naruto.

………………

Late at night, at Naruto's house.

The curtains were drawn, and only the dim light from the table lamp illuminated the room.

Naruto sat at his desk, fiddling with an empty teacup in his hand, his brows slightly furrowed.

Sasuke still needs time to grow.

However, this growth rate still seems insufficient in the face of the enormous mental burden of future shadow clones.

Naruto adjusted his glasses, his gaze calm.

"If we could find a way to directly train mental strength, or optimize the brain's capacity..."

Although there are methods for cultivating spiritual power in the ninja world, most of them are held by the Yamanaka clan or genjutsu families and are considered closely guarded secrets.

Since we can't find Konoha for the time being, let's broaden our horizons.

With a thought, Naruto opened the [All Heavens Forum].

The forum remains bustling with activity.

The homepage is filled with all sorts of strange posts:

"I turned a zombie into a true zombie, and my master said I was messing around. Is this considered innovation?"

Shocking! Does cross-dressing help you become stronger? The correct way to be a magical girl...

……

Naruto skillfully ignored these spam posts, edited a title, and clicked send.
