Please teach me, senior

Uchiha Fugaku froze for a moment. He had never imagined genjutsu could treat illnesses. Who used genjutsu for anything but killing?

But treating mental illness with genjutsu really was feasible. So many people had died tonight, and many villagers had lost relatives.

If genjutsu let them see their loved ones, it really could comfort them. It might even improve the Uchiha's reputation.

At that thought, Uchiha Fugaku crouched down and smiled as he patted Uchiha Yan's shoulder.

"You're right. The person you see in others is who you truly are.

"All I know is how to kill with genjutsu, but you thought of using it to save people.

"If it were you, how would you save people with Fire Release?"

"Lighting, cooking, sterilizing, keeping out the cold, warding off wild animals, clearing obstacles.

"You could also work with the Byakugan to check for survivors beneath the rubble, then use Fire Release to signal."

"Thank you! I know what to do now! Yan, let me thank you on behalf of the Uchiha."

"Clan leader!"

Uchiha Yan looked startled. "Why are you suddenly saying that? I'm still a kid. Don't scare me!"

"Hahaha... Go get some rest! We'll have a proper chat when we have time!"

"Oh..."

After Uchiha Fugaku left, Yan let out a long breath and lay flat on the tatami.

Too much had happened tonight. He had faced mortal danger as soon as he transmigrated, only to be captured by Danzo after barely escaping with his life. Then he had even had to match wits with the Third Hokage.

Something's strange. Why do I know how to speak Japanese? Is it habit? Subconscious behavior?

I should have read more about neuroscience back then. At least my head wouldn't be hurting now.

I'd better check the system first. I don't even know whether I imagined it.

System! Tianyan System! Are you there? Can you get the hell out here?

"Hello, user. How may I help you?"

What functions do you have?

"The Tianyan System can help the user deduce anything, including but not limited to methods of practicing ninjutsu, and match the most suitable path of growth to the user's circumstances.

"Please read the instructions carefully..."

A blue screen appeared before Uchiha Yan's eyes. There were several videos on it, each with text.

"How to use the Tianyan System!"

"Prompts for the Tianyan System!"

"How to obtain Deduction Points!"

"Heavenly Evolution..."

Uchiha Yan opened a video at random and watched. It took a full hour before he understood the system's capabilities.

Put simply, it was a DeepSeek that required spending, only more powerful.

Its strength lay in its ability to scan the terrain and surroundings within a two-kilometer radius. As for how it scanned them, there was no explanation.

That's nuts! The Shinobi World doesn't even have satellites. How the hell do you do it?

What the hell are Deduction Points? Isn't this just making me feed you? Ten ninjutsu for one deduction? Do you think ninjutsu grows on trees?

At least I can feed it documents, customs, and stuff like that. Otherwise, this system would barely be worth having...

Uchiha Yan kept grumbling inwardly and fell asleep without realizing it.

While Uchiha Yan slept, the Uchiha Clan split into two teams under Fugaku's leadership. One team focused on using genjutsu to soothe the villagers' wounded hearts.

The other used Fire Release to clear obstacles and open escape routes for ordinary villagers.

The Uchiha's actions left everyone's jaws on the floor. Hizashi Hyuga even suspected that the entire clan had gone mad!

"Brother! Genjutsu can save people? No, wait, the Uchiha save people? No, that's not right either. How did the Uchiha think of using genjutsu to save people?"

"You're asking me? Who am I supposed to ask? Those Sharingan tomoe in the Nine-Tails' eyes were no illusion, yet the Uchiha didn't take advantage of the chaos to attack Konoha. How strange."

"With Uchiha Fugaku's temperament, it'd take a miracle for him to dare rebel.

"No, wait, we're already seeing the impossible. The whole Uchiha Clan has gone mad!"

"Enough! Neji is already a year old. You should know what you can and can't say. Children are easily influenced."

"But Neji isn't here, is he? Besides, he's only one. What the hell does he know?"

It wasn't just the other villagers who couldn't understand the Uchiha. Even the Uchiha clan members themselves couldn't understand it, and helping people kept giving them goosebumps.

"What is the clan leader thinking? Who uses genjutsu to save people? Ask me to kill someone, sure, but I really can't handle saving people!"

"Who can? But what can we do? That brat Uchiha Yan kept telling the Third Hokage that the Uchiha were the kindest people around. If we don't do this, wouldn't that be saying the entire Uchiha Clan is full of liars?"

"Kind, my ass! Does he have any idea how many people I, Uchiha Jin, have killed? Even if he doesn't, doesn't the Third Hokage?

"Damn it! I really don't want to save people. There's something wrong with the way those people look at me. Why isn't there any hatred anymore?

"They should look at me with hatred. That way, I can kill them without any qualms later."

"This is all Uchiha Yan's fault. Once this is over, I'm definitely stabbing him with genjutsu for seven days and seven nights!"

"Enough talk. Here comes another kid who's had a mental breakdown. He can't even cry. If we don't help him, he might kill himself."

"Let him die..."

"..."

With the ninja helping, Konoha cleared the entire village in a single night. All that remained was to wait for funds to arrive before rebuilding.

At this point, the Third Hokage also announced the course of the previous night's battle and its losses. The greatest loss was the death of the Fourth Hokage and his wife. The news soon spread throughout Konoha.

Uchiha Yan was having breakfast with Itachi when he heard the news, and his face showed no surprise.

"Lord Minato died too?"

"No talking while eating or lying down to sleep! Don't talk during meals. You might choke to death."

Uchiha Itachi set down his chopsticks, his face full of confusion.

"Senior, what is the meaning of life?"

"You wouldn't understand even if I told you! Just focus on your studies and learning ninjutsu. Leave profound philosophical questions like that until you're older."

"Philosophy? What's that? Can I learn it? Also, the passage was pitch-black last night. How did you see the way, senior?"

"I'm a good person, so I naturally possess Haoran Qi. If you really want to learn, I'll teach you when there's a chance."

"I want to learn right now!"

??????

Uchiha Yan stopped drinking his soup, his head full of question marks. What was this supposed to mean? Couldn't he even tell when someone was lying?

"Itachi, I was just talking off the cuff. You should just take it lightly. How could you take it seriously?"

"But you could see in the dark, and you said the Third Hokage would come. Then he came soon afterward."

At that, Itachi slowly stood and bowed deeply to Yan.

"Please teach me Haoran Qi, senior!"

Teach you, my ass. Why are you so stubborn? You believe everything I say. If I said I'd eaten shit, would you believe that too?

Wait! This guy's such a filial son. If I reform him with Confucianism, he might not even awaken the Mangekyō Sharingan. Wouldn't that mean I'd averted a crisis without anyone realizing it?

At that thought, Uchiha Yan cleared his throat twice, then looked at Itachi expressionlessly.

"Uchiha Itachi, Haoran Qi is a supreme art from beyond this world. Unlike chakra training, this method of cultivation begins with studying and learning how to conduct yourself.

"Haoran Qi is utterly unyielding and purely yang. It arises from accumulated righteousness. You must not do anything that violates benevolence or righteousness, however slight.

"With success in its cultivation, at its highest you can cleanse the world of all evil; at its lowest you can cultivate yourself, bring order to your family, govern a nation, bring peace to the world, and establish peace for all generations.

"Yet this path is exceptionally perilous, beyond the abilities of ordinary people.

"To achieve this path, you must first temper your resolve through suffering, toil your muscles and bones, endure hunger, and suffer deprivation. Are you certain you want to learn?"

"Yes! Please teach me, senior!"
