Naruto: The Uchiha Calabash Brothers are reshaping the ninja world

The next morning.

After breakfast, Mo took Shisui to the woods near the Naga River to train, as usual.

However, after checking Shisui's training progress and providing corresponding guidance, Uchiha Mo did not notice anyone secretly watching him. However, he was not in a hurry and began to train step by step.

After telling Shisui to train on his own, Mo came to a century-old tree that took two people to encircle, and slowly gripped the black hilt of the sword at his waist.

"Whoosh—!"

With a clear, melodious sound like flowing spring water, the gleaming blade was slowly drawn from its sheath.

He held the Futsu-no-Mitama squarely in front of him, his indifferent black eyes fixed on the reflection of the straight blade.

"Let's test the knife first."

As soon as he finished speaking, Mo raised his straight sword and slashed it diagonally down at the tree!

"Pfft!"

He didn't use much force, just the normal force of a slash, yet Futsu no Mitama's entire blade plunged into the tree trunk, nearly severing half of it before finally stopping.

Mo slightly raised the corner of his mouth and drew his straight knife.

The fact that a single ordinary slash could be so powerful without any chakra attached is enough to demonstrate the sharpness of Futsu-no-Mitama.

Immediately afterwards, Mo gripped the straight sword tightly, took a deep breath, and with a sharp look in his eyes, activated the chakra within his body.

"Hey——!"

Accompanied by a sharp eagle's cry, dazzling lightning instantly covered the gleaming blade.

The unlocking of the "Thunderclap" ability allows Mo to mold Chidori at will, like kneading clay. Whether it's the Chidori system developed by Sasuke or the Lightning Blade system developed by Kakashi, he can use them as long as he has the will.

And at this moment, he was using the "Thousand Bird Blade".

With a flick of his wrist, almost instinctively he ensured that the entire blade of the sword remained in a straight line with the direction of the strike when he exerted force, and then he slashed the Futsu-no-Mitama diagonally toward the tree in front of him!

"Pfft!"

Mo knelt on the ground, the tip of his knife pointing diagonally at the ground, while the large tree in front of him slowly began to move.

"Crack—crack—crack! Boom—!"

  

The sturdy tree crashed down, and Mo stood up, sheathing his straight sword, a slight smile playing on his lips.

Based on the test results, the sharpness of Futsu-no-Mitama is at least no weaker than that of the Kusanagi sword in Sasuke's hand, and after using the same Chidori sword, its sharpness is even greater.

While the "Thunderstorm" might have enhanced the power of Lightning Release, the difference is clearly not something that can be compensated for by this single factor.

With such sharpness, in conventional taijutsu combat, even without the use of chakra, an enemy's weapon would rapidly lose durability upon impact with Futsu-no-Mitama, becoming unusable in just a few hits. And if chakra were added, a conventional ninja tool would likely be sliced ​​in two instantly, without a doubt.

After having a general idea in mind, Mo started to plan another matter.

That is to develop a new bloodline limit based on lightning release and fire release!

Lightning Release and Fire Release are the two most unstable of the five basic ninjutsu, possessing both explosive and high burst characteristics. There are many bloodline limits based on Fire Release and Lightning Release in the ninja world, such as Lava Release, Boil Release, Explosion Release, Scorch Release, Storm Shield, etc., but there has never been a bloodline limit that combines Fire Release and Lightning Release.

To fuse these two most unstable escape techniques into a new bloodline limit is no different from taking apart two extremely unstable bombs to form a more powerful one! Putting aside the difficulty, the cost of failure alone is unbearable for ordinary people.

Mo's reason for considering this was that he possessed both "fire control" and "lightning manipulation" abilities, granting him ultimate control over the transformations of both fire and lightning techniques. Furthermore, the versatile Chidori provided a convenient entry point, making it a feasible option. If he succeeded, he could simply train this new bloodline limit to directly increase the proficiency of two techniques, significantly increasing efficiency.

Without hesitation, Mo immediately extended his left hand.

"Chidori!"

"Hey——!"

A dazzling flash of lightning appeared, and surging lightning snakes danced wildly on Mo's left hand.

Immediately afterwards, Mo slowly controlled the fire chakra within his body and began to condense it...

"Red Blaze - Thousand Birds!"

Mo let out a low shout, and the lightning on his palm suddenly began to change!

Blue lightning crackled and trembled, slowly converging towards the crimson hue, and the temperature of the electric arc began to rise rapidly.

In just a few breaths, Chidori had turned completely blood-red, and the arcs of electricity seemed to be burning, the halo on its surface faintly revealing a translucent, flame-like quality, swaying with the wildly dancing lightning snakes. At the same time, a surging heat wave emanated from Uchiha Mo's palm, distorting the surrounding air!

Mo felt the violent force in his palm, and a bead of cold sweat involuntarily slid down his forehead.

"Such ferocious power! Is this the complete form of this technique...?"

Even as the controller of "Crimson Blaze: Thousand Birds," Mo was genuinely startled by this power. He felt that what he held in his hands was not a ninjutsu at all, but an out-of-control hundred-ton king, only this terrifying monster was moving in the right direction in a strange way.

Shisui was practicing swordsmanship on the side when this terrifying chakra aura erupted, startling him so much that he jumped up on the spot, his hair standing on end!

He used a Body Flicker Technique to create a distance of more than ten meters before turning back to look in Uchiha Mo's direction.

After observing nervously for a while, Shisui swallowed hard and shouted with extreme resentment, "Nii-san! Can you at least tell me before you start researching forbidden techniques next time?!"

Mo did not respond. His eyes had somehow transformed into the three-tomoe Sharingan, and he was intently focused on the technique in his hand, sensing the state of his chakra.

"The degree of Fire Release chakra nature transformation... the degree of Lightning Release chakra nature transformation... the ratio of Fire and Lightning attributes mixed together..."

Mo stood motionless in place, like a stone statue, focusing all his energy on recording every aspect of the fusion of Fire Release and Lightning Release in his mind.

After an unknown amount of time, until his chakra was completely depleted, Mo stopped outputting chakra, put away his Sharingan, sat cross-legged on the spot, closed his eyes, and began to gather chakra.

Another half hour passed, and Mo, feeling that his chakra had recovered to a certain extent, couldn't wait to open his eyes and start experimenting again.

According to the information he had just recorded, he controlled the lightning chakra and fire chakra to merge in his body in a one-to-one replica, but a strange thing happened.

The ink had clearly perfectly replicated the chakra situation from "Crimson Blaze: Thousand Birds," but there was no sign of the lightning and fire merging...

"What... what's going on... why can I use the technique, but not the autonomous fusion..."

Mo frowned deeply, completely baffled.

"Is it because the Chidori's shape changes are quite unique?"

"..."

"No, bloodline limit is just a fusion of two chakra nature transformations, and has nothing to do with form transformation..."
