The entire Hokage's Office fell into a strange silence.
Orochimaru just stood there, holding the "On the Fundamentals of the Interaction Between Electricity and Magnetic Fields" which felt as heavy as a thousand catties, flipping through it rapidly.
His brain was experiencing an unprecedented storm.
Electricity generates magnetism, magnetism generates electricity.
Electricity and magnetism are two sides of the same coin.
These theories were like keys, instantly unlocking countless difficult problems about energy conversion that had been locked in his mind.
Why couldn't electricity be stored?
Because we had been trying to store "flowing river water" without thinking about turning it into a "still lake" first.
Why couldn't electricity be transmitted over long distances?
Because we had been using "tiny water pipes" to transport a "raging torrent." The huge energy would naturally be consumed by friction and resistance during transmission.
If...
If we could use the principle of "magnetism generating electricity" to build a device that first converts the high-intensity, unstable current generated by the generator into a low-intensity but more stable form, and then transmit it.
When it reaches the destination, use another reverse device to turn it back into high-intensity current.
Then... wouldn't that solve the problem of loss in long-distance transmission?
Orochimaru's breathing became faster and faster.
He flipped through the manuscript in his hand rapidly.
"Electromagnetic induction... Faraday's law... Left-hand rule... Right-hand rule..."
Terms he had never heard of, yet seemed to contain the ultimate principles of the universe, constantly impacted his cognition.
The manuscript not only contained detailed theoretical explanations but also sketches of various experimental devices personally drawn by Sarutobi Hiruzen.
For example, a strange device composed of two coils of different sizes, named by his teacher as a transformer.
Next to the sketch, there was a clear annotation.
"By changing the turns ratio of the primary and secondary coils, the voltage can be freely changed. Step up, or step down."
Step up! Step down!
Seeing these four words, Orochimaru's body trembled violently.
He understood!
He completely understood!
All previous failures were because they had been trying to use "brute force" to confront the energy of "electricity."
But his teacher had long stood on a higher dimension, telling him to learn to use the laws to "guide" it, to "transform" it.
This... what wisdom is this!
Orochimaru looked up, looking again at the man who was leisurely sitting in his chair sipping tea.
At this moment, the awe in his heart was beyond words.
Holding the book, his hands trembled violently with excitement.
With a gaze as if looking at a god, he stared deadly at Sarutobi Hiruzen before him, his voice hoarse beyond recognition, and asked the question that had been stifled in his heart for a long time.
"Teacher..."
"Is there anything in this world... that you don't know?"
Sarutobi Hiruzen put down his teacup, looking at Orochimaru's shattered worldview and doubtful life. On the surface, he put on a lonely expression of being too high up to be reached, and in a tone filled with the vicissitudes of someone who has been there, he said lightly, "Orochimaru, the ocean of knowledge is endless."
"What I know is but a drop in the ocean."
"Your future path is still very long."
With that, he stopped looking at Orochimaru and picked up the document on the table again, as if the conversation just now, which was enough to subvert the entire ninja world, was just an ordinary tutoring session to him.
And Orochimaru, upon hearing these words from his teacher, was shocked beyond measure.
A drop in the ocean?
Orochimaru felt that his worldview had been repeatedly crushed, reshaped, crushed again, and reshaped again by his teacher in just a few minutes...
He took a deep breath and bowed deeply, very deeply, to Sarutobi Hiruzen.
"Teacher, I... I understand."
With that, Orochimaru said no more. Clutching the manuscript tightly as if holding the world's most precious treasure, he turned and rushed out of the Hokage's Office without looking back.
He had to return to the laboratory immediately.
Let the light named electricity illuminate the entire Konoha!
Watching Orochimaru's back as he left in a flurry of excitement, Sarutobi Hiruzen smiled with satisfaction.
Done.
"Sigh, geniuses sometimes just get stuck in a rut," he shook his head and silently complained to himself.
Complaints aside, Sarutobi Hiruzen was in a very good mood.
Once this research fanatic Orochimaru had his tech tree unlocked, the energy he would unleash would be absolutely astonishing.
He could almost foresee how brilliant Konoha would be in the near future.
"Take it step by step... can't stride too fast."
"...The Hyuga family's Byakugan vision... paired with a railgun... hmm... could be used for sniping..."
Having solved the electricity problem, Sarutobi Hiruzen was in a great mood. He stretched and decided to get off work early today.
He stood up, put on the Hokage hat, and disappeared from the office in a flash.
