A Special Lesson – Explaining Chakra and the Meridian System
That morning, Satoru entered the classroom with a mysterious smile, carrying a large board with a detailed diagram of the human body and its intricate meridian system.
The students stared at it, curiosity burning in their eyes.
He calmly wrote two large words on the board:
"CHAKRA & MERIDIANS"
Immediately, excitement spread across the room.
Rin eagerly raised her hand, her voice filled with enthusiasm.
"Sensei! Isn't chakra simply the energy used to perform jutsu?"
Kakashi, arms crossed, responded in a measured tone:
"Chakra is the combination of physical and spiritual energy, flowing through meridians to create jutsu."
Satoru nodded, but his mysterious smile didn't fade.
"Kakashi's answer is not wrong, but it's also not complete. Chakra is not just an energy source—it is the very foundation that dictates how the human body functions in the ninja world."
He began sketching a detailed network of meridians, similar to acupuncture charts in Eastern medicine.
Flashback – Why Did Satoru Know About Meridians?
As he drew on the board, Satoru paused for a brief moment.
He stared at the intricate web of meridians, a strange sense of familiarity creeping into his mind.
This wasn't just knowledge from Naruto.
He had seen these diagrams before.
Not in any anime or manga—
But in his grandfather's ancient medical texts.
Flashback: His Grandfather and the Secrets of Meridian Healing
Satoru's grandfather was an expert in Eastern medicine, specializing in herbal remedies and acupuncture.
As a child, Satoru often listened to his grandfather talk about the flow of energy through the human body, how acupuncture could unblock energy pathways, strengthening the muscles, mind, and overall vitality.
Back then, he had thought it was just old folklore.
But after obsessing over Naruto for years, he made a startling realization—
The meridian system in Naruto bore a striking resemblance to real-life Eastern medical theories.
Chakra was remarkably similar to "Qi", the life force spoken of in ancient medicine.
The chakra points in Naruto matched almost exactly with acupuncture pressure points.
And now, standing in this classroom as a teacher, he finally understood—
Everything he had learned from his grandfather and his years as a weeb… was not wasted.
A small smile formed on his lips as he silently thanked his late grandfather.
The Meridian System – The True Flow of Chakra in the Human Body
Satoru pointed to the detailed diagram and began his lecture.
"The human body contains an intricate meridian system with 361 major chakra points, all interconnected through hundreds of smaller pathways. You can think of them as chakra acupoints. The strongest shinobi are those who can unlock and utilize the full potential of their chakra pathways."
The students stared in awe, their jaws slightly open.
Gai clenched his fists, eyes shining.
"Sensei! Does that mean the more meridian points we unlock, the stronger we become?"
Satoru nodded, his gaze sharp.
"Exactly. The more chakra points you activate, the greater your potential. This is why some people are born with abundant chakra reserves, while others have very little."
Beside Gai, Obito clenched his fists.
They both shot a glance at Kakashi, the same thought running through their minds.
"Just wait, Kakashi! We'll surpass you!"
Kakashi remained expressionless, but deep down, he was intrigued.
For the first time, he saw Gai and Obito truly determined.
And more importantly—
He found himself genuinely interested in the lesson.
"Maybe… school isn't as bad as I thought."
Why Do Kage Specialize in Certain Chakra Natures?
Satoru wrote five words on the board:
FireWaterWindEarthLightning
Then, he turned to the class.
"Why do Mist shinobi excel at Water Release? Why are Raikage famous for Lightning Release? And why is Fire Release synonymous with the Uchiha?"
Obito puffed his chest proudly.
"Because Uchiha have the Sharingan—so we naturally excel at Fire Release!"
Satoru shook his head, smirking.
"That's not the reason."
The class fell silent.
He continued, his voice steady.
"It's because of chakra affinity shaped by geography. Each ninja village naturally develops a dominant chakra nature due to its climate, terrain, and environmental conditions."
He pointed at the elements on the board:
Mist Village is surrounded by water sources and high humidity, making Water Release the most naturally powerful there. Cloud Village sits atop high altitudes, constantly bombarded by thunderstorms, leading to an innate affinity for Lightning Release.Stone Village is built on solid rock and mountains, making its chakra naturally align with Earth Release.Leaf Village has a balanced environment, allowing for varied affinities, but Fire Release became dominant due to historical battle traditions of the Uchiha Clan.
The entire classroom was hooked, hanging onto every word.
For the first time, no one was dozing off.
System Activation – Meridian Unlocking and New Progress
As the lesson ended, the system's voice echoed in Satoru's mind.
[Congratulations! You have completed an advanced lecture on Chakra!]
[You have received special rewards!]
✔ Meridian Unblock – Increased Chakra Potential ✔ Mid-Level Proficiency in Fire and Lightning Release ✔ Advanced Genjutsu Mastery
Satoru almost laughed out loud in excitement.
He could feel his chakra flowing smoother than ever before.
A new path had opened for him.
And tonight—
He would officially begin training his three disciples.
