Teaching According to Their Strengths-I Don't Develop Forbidden Jutsu. I'm Just the Courier!

Qi Luna looked at the three whose resolve remained unshaken, and felt more satisfied with them than ever.

He took out the Initial Scroll from his ninja pouch, summoned a notebook from within it, then summoned a set of notes and two ninjutsu scrolls from different pages in the notebook.

He handed the notes to Yahiko, then gave the two ninjutsu scrolls to Konan and Nagato, respectively:

"Yahiko, these are Water Release Ninjutsu developed by the Second, along with his and my notes on the nature transformation of Water Release chakra."

Yahiko's eyes widened, and even his breathing grew ragged:

"T-The Second's Water Release?!"

"You have six months to learn every jutsu in these notes and complete the nature transformation of Water Release chakra!"

"This will make up for your lack of mid- and long-range attacks, while preparing you to train in the fifth form of Vortex Style Nintaijutsu. If you can't do it... I'll show you what it means to 'wish you were dead'!"

Qi Luna's tone was firm and left no room for argument. His final threat carried such immense malice and killing intent that Yahiko couldn't help swallowing nervously.

"Yes! I'll complete the mission!"

He was afraid of the punishment if he failed, but as long as he succeeded, there was nothing to worry about, right?!

Yahiko eagerly took the notes, cradling them as if they were a priceless treasure.

What Qi Luna gave Konan was a black scroll covered in sealing script. It already had several layers of protection, yet he had added several more seals to this scroll alone. That made it clear this jutsu was no ordinary technique!

"Konan, this is the scroll for the Mutually Multiplying Explosive Tags, a forbidden jutsu developed by the Second!"

"It was the Third Hokage's reward to me for my distinguished service during the Second Shinobi World War!"

Qi Luna's voice turned unusually serious:

"This jutsu is tremendously powerful, but it also poses a great danger to its user. Once activated, it summons a large number of Explosive Tags in an instant, leaving the user little chance of escaping the blast radius. That's why it was classified as a forbidden jutsu! Since the Second's time, no one else has chosen to learn it!"

"It's a double-edged sword. It could put you in grave danger, but it could also become the ultimate killing move of your Dance of the Shikigami!"

"Your task now is to combine it with the properties of Paper Style and work out the beginnings of your own controllable version of 'Mutually Multiplying Explosive Tags'! You could have a Paper Clone carry the Explosive Tags, move far away, and then activate the forbidden jutsu; directly control the tags to activate it from a safe distance; or try something else. Any of those could work!"

"At the same time, you need to refine the defensive form of your Dance of the Shikigami, incorporating different chakra nature transformations so it can withstand flames, torrents, oil, and even corrosive substances!"

"If you manage all that, then your future battlefield will be the sky, and your art will last only an instant!"

Konan took the black scroll. As she touched the secret sealing technique on it, her fingers trembled slightly, yet an unprecedented light shone in her amber eyes:

"Yes, Teacher Qi Luna! I'll master it perfectly!"

Qi Luna smiled and patted Konan on the head, saying softly:

"Good. That's the spirit. But don't practice with real Explosive Tags until you've mastered it. Just use ordinary shikigami paper to practice the multiplied summoning."

"Once you've mastered multiplied summoning, try controlling it from a distance. Then learn how to make Explosive Tags. Only after you understand all of that can you begin formally training in the Mutually Multiplying Explosive Tags under my supervision!"

Konan lowered her head shyly, her cheeks quickly turning red. She fidgeted with the shikigami paper in her hands and murmured:

"I understand, Big Brother Qi Luna."

Qi Luna nodded, then turned his attention to Nagato.

He handed Nagato a blue ninjutsu scroll with the character for "armor" written on its surface and said gravely:

"This is a spoils of war I seized during an Anbu mission. It's only a B-rank Lightning Release Ninjutsu, but it's a powerful jutsu that the Second Raikage of Kumogakure devoted himself to researching and developing!"

"Lightning Release Armor, also known as Thunder God Armor. You may not recognize those names, but it has another familiar one: 'Lightning Release Chakra Mode'!"

"This isn't a jutsu for directly attacking an enemy. It uses Lightning Release chakra to stimulate your cells, strengthening your body, nerve reflexes, and endurance to their absolute limits!"

"The training is extremely painful, like being cut by a thousand knives. And your Rinnegan is already eating away at your chakra and life force, Nagato, so training in this will be even harder for you!"

"But this is the best way for you to escape your current situation. Whether or not to train in it... that choice is yours."

After hearing Qi Luna's explanation, Nagato smiled brightly and solemnly accepted the ninjutsu scroll. The choice he would make was already obvious.

"Ahem. Pay attention!"

Qi Luna's tone suddenly grew sharper as he fixed his eyes on Nagato's Rinnegan:

"Since you've made your choice, while you train your body with Lightning Release, I'll reinforce the seal on your Rinnegan, filling it with Nine-Tails Chakra and some of my own life force. That should temporarily free you from the strain of the Rinnegan."

"But you mustn't neglect ordinary ninjutsu training in the five basic chakra natures. You need to master the shape and nature transformations of all five chakra types, become proficient in all five elements, and learn to use compound techniques combining different natures!"

"Nagato, I want you to become a perfect ninja with no weaknesses! Remember, the Rinnegan will be your trump card, but it won't be everything! The more hidden cards you have, the better! Understood?!"

Feeling the depth of Qi Luna's expectations, Nagato's purple Rinnegan shone with determination:

"Understood, Brother Qi Luna! I'll master Lightning Release Chakra Mode, and I won't neglect any of the basic ninjutsu training!"

"Once my body is strong enough to bear the Rinnegan, I'll be able to fully control its power!"

Qi Luna gazed at his three disciples, each holding a training plan tailored to them, their eyes brimming with determination. They were like three uncut gems. Given enough hardship and refinement, each would surely shine with a brilliance all their own!

"Excellent! All three of you are doing great!"

"Get started. Over the next six months, I'll watch you transform yourselves completely!"

Qi Luna's voice echoed across the training ground, carrying unquestionable authority and boundless expectation:

"Remember, your goal has never been to surpass anyone. It's to become worthy inheritors of the Will to Protect! To become true powerhouses who can stand on your own and protect what you hold dear!"
