Naruto: Help Madara rejuvenate and launch a counterattack on Konoha

Actually, there is a source in the original work.

That was Naruto's Sage Art: Lava Release: Rasengan, which he used with the help of the Four-Tails' Lava Release chakra.

Naruto added Sage Mode, Fire Release, and Earth Release to the Rasengan, creating a technique that combines these three elements. This technique possesses the power to burn, cut, and explode.

This is beyond the realm of forbidden techniques; even immortal arts aren't this exaggerated. This is practically cheating.

It has no reference value whatsoever.

In theory, the Rasengan can have all its attributes developed.

Thunder, fire, earth, and water are all acceptable.

Liao Wu chooses fire.

What can fire do?

Fire can burn, release high temperatures, and explode.

Liao Wu focuses on the explosive properties. First, he must inject fire-attribute chakra into the Rasengan, then endure the high temperature and control the terrifying explosive power.

Finally, we'll figure out a way to throw it out.

This is an explosive Rasengan, similar in nature to the Wind Release Rasengan. It will affect the user, so a way must be found to throw it away.

This requires even stronger chakra control.

Liaowu slowly tried to replicate the process using spores.

A blue-white spiral sphere of light condensed in Liao Wu's hand.

This is the normal Rasengan.

Then, Liao Wu infused it with his fire-attribute chakra.

The blue and white color inside the Rasengan turned fiery red, making it look like a fireball spinning at high speed.

It radiates terrifying heat and astonishing explosive power.

The spore clone has already taken shape; all that remains is for Liao Wu to gradually perfect it.

The entire room became scorching hot, and Obito, sweating profusely, stared in horror at the fire-attribute Rasengan in Ryou's hand.

"Liaowu, what are you doing?"

Afei was also somewhat frightened: "Lord Liaowu, be careful. If the technique in your hand explodes, the entire Akatsuki base will be blown to smithereens."

As the saying goes, "Fine wine in a luminous cup, the dawn's base flies in the sky."

If Liao Wu is not controlled properly, not only him, but everyone in Xiao will be buried with him.

Liao Wu scoffed, "What's there to be afraid of? It's just ascension, no big deal!"

"Liaowu, Liaowu, don't speak, it's about to explode!"

"My lord, my lord, please don't be distracted. I don't want to die yet."

A sound suddenly came from outside the door.

"Lord Konan!"

"Great Buddha, I've come to learn medical ninjutsu from Grandpa Wu."

"I see!"

Because Liao Wu saved the Buddha's life, he is now the Buddha's second parent, and the Buddha cannot find any other way to repay him.

He was assigned to guard the gate for Liao Wu and serve as his bodyguard.

Liao Wu quickly withdrew his Flame Rasengan, then punched Obito, Tobi, and Black Zetsu, three inhuman creatures, deep into the ground.

Tell them not to ruin their plans.

"That guy is a scoundrel! He's definitely going to deceive innocent girls, we have to stop him!"

"Stop your dam! Obito, don't disturb Lord Liaowu."

The Buddha informed Liao Wu, who then used a transformation spell to become an old man and let Xiao Nan in.

When Xiao Nan entered, she sensed a scorching heat in Liao Wu's room, as if a thick fire was burning inside.

She was somewhat puzzled.

Liao Wu explained, "It's always rainy in the Land of Rain, so the cave was a bit damp. I just released a little fire to drive it away."

Xiao Nan nodded, still holding a bowl of porridge in her hand. Xiao Nan was quite thoughtful, considering that Liao Wu might have trouble chewing it, so she specially made porridge.

"Grandpa Wu, we don't have much to offer you, just some porridge!"

Liao Wu took the porridge from Xiao Nan's hand: "Xiao Nan, you are so virtuous. If I were still the same as before, I would definitely marry you."

Xiao Nan smiled.

After Liao Wu finished his porridge, he had Xiao Nan sit in a chair.

"Konan, the training for medical ninjutsu is very rigorous. Are you mentally prepared?"

Xiao Nan nodded firmly: "Grandpa Wu, don't worry! For Xiao, I will overcome any difficulties."

Liao Wu nodded: "Okay, take your clothes off first!"

"!!(ﾟДﾟ≡ﾟдﾟ)!? Huh?!"

Xiao Nan stared at Liao Wu in shock. She knew how difficult it was to cultivate medical ninjutsu, but not this kind of hardship.

"What do you mean? This is how we medical ninjas train. Otherwise, why are there so few medical ninjas?"

Liao Wu coughed violently, coughing so hard that he coughed up blood.

Xiao Nan quickly stepped forward to clean the blood from Liao Wu's mouth.

"Grandpa Wu, can you stop teaching me? What you need most right now is rest."

Liao Wu said weakly, "Xiao Nan, stop talking nonsense. I'm about to die. Just do as I say, and I'll pass on all my medical ninjutsu to you."

"Okay, fine!"

Seeing Liao Wu's near-death appearance, Xiao Nan guessed he was already beyond saving. How could she doubt Liao Wu's ulterior motives when he had such a pure and innocent heart?

Besides, what's there to be ashamed of about ninjutsu?

……

black market.

Yahiko and Nagato went to town, and, covering their noses, they passed through a secret passage in the public toilet to reach the black market of the Land of Rain.

They approached the head of the black market, wanting to buy a batch of ninja combat supplies.

Kunai, shuriken, explosive tags, and the like.

The black market manager and his men helped Nagato and Yahiko get ready.

Yahiko reluctantly paid the money. You can get anything on the black market, but the price is ridiculously high, and there's always the risk of buying counterfeit goods.

A while ago, Yahiko and his group bought a batch of fake detonating tags.

He immediately cursed, "Whoever designed this, even the detonation tags have to be faked?"

As he was leaving, Yahiko suddenly stopped and asked the black market manager, "Do you know someone named Ryou-wu?"

Nagato looked at Yahiko with a questioning look. Ryo had treated Akatsuki with all his heart, yet Yahiko still suspected him of having ulterior motives. To be honest, that was a bit unfair.

Yahiko explained to Nagato, "Please calm down, Nagato. I know that Grandpa Wu is a great philanthropist, but I also want to know his background."

"After all, such advanced medical ninjutsu couldn't have been learned by a wanderer."

Nagato remained silent.

Yahiko is right. The three of them are where they are today because of Jiraiya's teachings. Ryougo's secret technique, which can almost bring the dead back to life, could not have been learned from wandering.

The black market manager asked in confusion, "Liao Wu?! You mean Uchiha Liao Wu? It's such a pity about him!"

"Uchiha Ryougo?!"

Nagato and Yahiko exchanged a glance, seeing the deep dread in each other's eyes. Ryogoku at home really was that beast that Jiraiya-sensei had described!

"Quickly, tell us what's going on with this Uchiha Ryougo?"

"Alright, alright, don't panic, let me explain slowly!"

"This Uchiha Ryou is a ninja from the Uchiha clan. He developed a forbidden technique—"
