Heart of Steel Half-Morph Sword Saint, Madara is willing to call me the strongest

Uchiha Yi followed Sennin Fukasaku out of the hall.

Seeing that the matter was over, Jiraiya and Minato took the lead to say goodbye, leaving Uchiha Yi alone to practice in Myoboku Mountain.

"Yi, you have already learned the magic of Ryuchi Cave, right?" Fukasaku asked.

"Yes, I just mastered it not long ago." Uchiha Yi nodded.

"The senjutsu of Ryuchi Cave is more feminine, and the senjutsu chakra tends to go wild, which can make people very strange and even affect their spirit. Although it is very powerful, it cannot compare to our Myoboku Mountain in terms of the balance between senjutsu and the human body. You should focus on our Myoboku Mountain's sage mode in the future."

The Immortal Fukasaku seemed to be disdainful of the magic of Ryuchidong and looked down on it.

This is also because the relationship between Myobokusan and Ryuchido is very bad.

There were even major battles between the two sides.

Uchiha Yi looked at the Sage Fukasaku and responded, "The Ryuchido Sage Technique will have a great impact on my appearance, but it is indeed not as good as Minato-senpai's Sage Mode in this regard."

"You're right."

Fukasaku Sage smiled faintly and agreed, "With your talent, you will definitely learn quickly. It took little Jiraiya more than a year to master the Sage Mode, and little Minato more than two months. You will definitely be faster than them."

Uchiha Yi followed Sennin Fukasaku to a spacious open space.

After waiting for a while, Sage Shima handed a red scroll to Uchiha Yi.

"Yi, let me first give you a brief introduction to the Sage Mode of Myoboku Mountain."

"Before practicing Sage Mode, you must first understand natural energy. Sage Mode, in short, is to control the vast natural forces in the world. Imagine that chakra is a fusion of our spiritual power and physical power, and Sage Technique is based on this and then integrates natural energy. These three must maintain a perfect balance."

"Once the balance is broken, the consequences will be disastrous."

Fukasaku Sennin's expression suddenly became serious. He pointed at the numerous stone frogs around him and said in a deep voice, "Look at these stone frogs. They all became like this because of the failure of the fusion magic."

"You have already mastered the magic of the Ryuchidong, so let's skip the step of sensing natural energy."

"What you have to do is to perfectly fuse the natural energies and form the senjutsu chakra of our Myoboku Mountain in proportion."

"I'll tell you the key point..."

……

Seven days later.

In a valley in Myoboku Mountain.

Uchiha Yi sat cross-legged on a huge plant.

In front of this plant, there is a waterfall with splashing water.

There is a small pool below the waterfall. In the center of the pool, there is a stone sculpture of a toad with a special shape. The liquid flowing out of its mouth is slowly pouring into the pool.

What flows in this waterfall and pool is not water, but toad oil. This toad can help humans absorb natural energy.

It was with the help of Toad Oil that Naruto quickly mastered the Sage Mode.

Since Uchiha Yi has mastered the method of obtaining natural energy, he no longer needs the assistance of toad oil.

But because of the toad oil in the pool in front of him, this place has become the place with the richest natural energy in Myoboku Mountain.

It also greatly improves Uchiha Yi's speed in absorbing natural energy.

"The perfect Sage Mode is indeed difficult to master, but I have succeeded in the core Sage Chakra fusion."

There were some signs of frogification on Uchiha Yi's face, but they were not obvious, somewhat similar to the state when Jiraiya activated the Sage Mode.

Uchiha Yi stopped practicing and stood up.

Because of his experience in practicing the Ryuchidong fairy art, it didn't take him too long to master the Myobokusan's fairy mode.

"As expected of a young man that is valued by the master, his talent is truly incredible."

Fukasaku Sennin showed a little surprise and looked at Uchiha Yi.

He was able to master the Myoboku Mountain magic in just seven days, a speed he had never seen before.

"I didn't expect Yi to master it in just seven days. Damn it, the fastest one before took almost a month."

"I can't remember clearly. Minato should be the fastest one before. It took at least more than a month."

Sennin Shima looked at Uchiha Yi with surprise in his eyes.

No wonder the master attaches so much importance to this young man.

The person who could be summoned by the master himself is indeed not an ordinary person.

"Yi, let's stop here for now and have lunch first."

Immortal Shima waved towards Yi.

"Uh...thank you two immortals, I don't need any more, you guys eat."

Uchiha Yi was stunned for a moment, looking at the two large bowls of insects in Sage Shima's hands, the corners of his mouth twitched slightly.

This kind of insect may indeed be delicious in the eyes of toads.

But, I am human.

"Yi, come and have a taste. The kid's cooking skills are really good. These bugs are freshly caught. They are very fresh."

As Fukasaku Sennin spoke, he ate the green bugs in the bowl with big mouthfuls.

"No, I brought my own food."

Uchiha Yi quickly refused.

He took a deep breath and slowly exited Sage Mode.

Taking advantage of this gap, he adjusted the disordered breath in his body, and took out two military ration pills from the ninja tool bag on his waist, put them in his mouth, chewed them gently a few times, and swallowed them into his stomach.

In this way, Uchiha Yi practiced quietly in Myoboku Mountain, and his mastery of fairy arts became more and more proficient.

……

Another half month passed.

Uchiha Yi, who was sitting cross-legged, opened his eyes.

I saw a faint orange-red eye shadow appearing around his eyes, and his pupils turned golden yellow.

Compared to Naruto's perfect Sage Mode, Uchiha Yi's Sage Mode is still lacking, but it is not far from the perfect Sage Mode.

At this moment, the practice of the Myoboku Mountain Sage Mode can be said to have been completed.

Uchiha Yi came to an open area nearby, ready to test the power of Myobokusan's magic.

He closed his eyes, took a deep breath, and felt the senjutsu chakra flowing through his body.

Uchiha Yi concentrated his mind and guided the fairy chakra to flow in his body. Then he took a deep breath and suddenly ejected a huge fire dragon from his mouth.

"Immortal Technique: Fire Dragon Technique!"

This fire dragon formed by fairy chakra has a diameter of more than thirty meters. Wherever the fire dragon passes, the surrounding area is scorching hot, and the entire sky seems to be covered by the fire dragon.

"Whoosh-"

The fire dragon rushed towards the ground with a roar that tore through the air.

With one blow, the entire ground was instantly burned red, forming a huge charred pit.

Uchiha Yi looked at this scene and nodded with satisfaction. The power of the Myoboku Mountain magic was indeed extraordinary.

Compared to the magic of Ryuchi Cave, the magic of Myoboku Mountain seems to be easier to control.

"Well, let's try the power of Senjutsu Chakra combined with the Kusanagi sword next."

Uchiha Yi clenched the shadow blade in his hand. With the influx of fairy chakra, a golden light surged on the sword of the shadow blade, as if it was coated with a layer of gold.

This light not only makes the sword more dazzling, but more importantly, it greatly enhances the sharpness and destructive power of the shadow blade.

Uchiha Yi slowly raised the Shadow Blade and felt the power coming from the sword.

He swung his sword, and there was a sharp sound of breaking wind in the air. A golden sword light cut through the sky, leaving a dazzling trail.

Wherever the sword light passed, the grass and trees broke, the rocks shattered, and it seemed that even the void was cut by the sword light.
