I developed the devil fruit seal in Naruto

Chapter 66: Heat Breath Evolution, Roar of the Thunder Flame Dragon!
When Orochimaru saw that Uchiha Kyon's Lightning and Fire Chakras gradually stabilized and were perfectly combined with the Dragon Man transformation, his vertical pupils shrank slightly and he felt extremely tricky.

The lightning escape technique increases speed, the fire escape technique strengthens attack, and the hardness of the dragon scales can even defend against the Kusanagi sword.

This was the first time in Orochimaru's life that he had seen a ninja with all the attributes of speed, attack, and defense, and almost no weaknesses.

He felt a little regretful. He shouldn't have agreed to Danzo so easily and came to Konoha without any preparation.

If we could wait until the Impure World Reincarnation technique is completed, or bring the four Sound Ninjas to cast the Four Purple Flame Array barrier, it wouldn't be as troublesome as it is now.

"Fortunately, Danzo has transferred all the Anbu around the Uchiha clan's territory, and has also tied up Sarutobi-sensei and the others. This place shouldn't be discovered in the short term."

"But with my preparations this time, it will be very difficult to catch the kid who has the power of dragon and the Sharingan, not to mention going to the Konoha Guard to catch his sister."

“I didn’t expect things to turn out like this.”

Orochimaru was calculating quickly in his mind, thinking about what to do next.

He quickly made a decision to test again how strong Uchiha Kyon's dragon power was.

"Huh?" Orochimaru was surprised, "Is it an illusion?"

Kabuto Yakushi followed his orders and went to search Uchiha Kyon's house, perhaps he would find something unexpected.

But he has only one weakness, that is, in the process of reincarnation, his soul power inevitably weakened a lot, resulting in his poor resistance to illusions.

Even if we don't get it this time, having the intelligence will make it easier to take action next time.

Uchiha Kyon's figure was clearly there, but the hurricane passed through his body.

"Sure enough." Orochimaru, who was on top of the black snake's head, let his tongue droop down to his chin, "But don't underestimate my perception."

Susu~
The black snake slithered across the ground, its trajectory unpredictable.

In addition, more importantly, he had to buy time for his subordinate, Pharmacist Kabuto.

Three pitch-black magatama appeared in the golden dragon's eyes, causing its pupils to emit an eerie scarlet glow.

Wisps of white mist floated out of Uchiha Qiong's mouth, and there was not much expression on his face.

Hongdou rushed over at this time, first looked at Uchiha Kyon's majestic figure wrapped in lightning and fire in shock, and then said:
"Be extra careful, Orochimaru is not that easy to deal with!"

Uchiha Kyon snorted.

"Psychic art!"

huh~
Uchiha Kyon disappeared instantly.

As soon as he opened his mouth, a violent hurricane blew out.

Orochimaru pressed the ground with one hand and summoned a huge black snake, which was longer and thicker than the gray-brown snake that died before.

To be honest, with the many strange and bizarre forbidden techniques he mastered, he was not afraid of most ninjas in the world, even those who were stronger than him, such as the leader of the Akatsuki organization, Tendo Pain, who possessed the Rinnegan.

"Wind Escape·Big Breakthrough!"

The black snake was spitting out its tongue. Orochimaru stood on top of the black snake, looking down at Uchiha Kyon. His face was as white as a zombie, and he was filled with greed and curiosity:
"Let me see if a dragon is really more powerful than a snake!"

With the insight of the Sharingan, no matter how fast the black snake is or how unpredictable its trajectory is, it cannot escape his eyes.

He suddenly turned around and looked to the left.

Ordinary illusions couldn't do anything to him, but the advanced eye illusions activated by the Sharingan could greatly restrain him.

Whoosh whoosh!
In addition to the Uchiha Kyō on the left, there were three more Uchiha Kyōs attacking him on the right and above and below.

Orochimaru frowned:
"No, it's not an illusion, a shadow clone? But the big breakthrough didn't hit the entity, could it be... similar to Shisui's instant body that can switch back and forth between the phantom and the entity?!"

Even Orochimaru had heard of the name of Shunshin Shisui.

"You reacted, but it's too late."

Uchiha Qiong shouted coldly, and threw out his fist wrapped in lightning and fire:

"The Iron Fist of the Thunder Dragon!"

Boom boom! !
Indescribable terrifying force was released on the black snake's body.

The black snake screamed in pain, and its upper body exploded, blown into pieces by the shock wave of thunder and fire. The broken flesh and snake blood dyed the ground beneath its feet red.

Orochimaru was not feeling well either. It seemed as if his boneless body was twisted into a doughnut, paralyzed by thunder and burned by flames.

His hair was disheveled and he was screaming like a madman. His voice sounded like fingernails rubbing against a blackboard and was extremely unpleasant to the ear.

Uchiha Kyon's shadow returned to its original form and was about to pursue the victory when Orochimaru suddenly stretched his neck, revealing his sharp fangs, and bit Uchiha Kyon's shoulder.

"The Poison of the Curse Seal!"

He wanted to plant a curse seal infused with snake venom on Uchiha Kyon.

But unfortunately, his fangs could not break through the triple defense of fire, thunder and dragon scales. Before it touched Uchiha Kyon's skin, the venom evaporated and his face melted, looking extremely creepy.

"I see. It turns out you are also using a kind of curse seal technique!"

Orochimaru's face melted into liquid and dripped down, his tone full of disbelief and a hint of surprise.

He once studied the curse technique of combining humans and beasts in the Sea Kingdom. In the original work, Mizuki obtained this curse and could transform into a half-human, half-tiger.

Later, Orochimaru felt that the power of this beast-transformation curse seal was very mediocre. Since he found Jūgo and discovered the secret of sagehood in Jūgo, his research direction has completely turned to the sagehood curse seal.

The Curse of Heaven and the Curse of Earth that he has basically developed now are far more powerful than the beast-type Curse.

Unexpectedly, one day, the beast-transformation curse that he had given up could be seen on someone else.

And in terms of quality, the beast transformation that Uchiha Kyon is currently using is completely not on the same level as what he had researched at that time.

It seems that he did not have a deep understanding of the beast-transformation curse at the beginning.

But it doesn’t matter, it’s not too late to know now.

As long as the direction is clear, Orochimaru is confident that with his scientific research level, he will be able to develop a beast transformation seal equivalent to Uchiha Kyon sooner or later.

Maybe one day in the future, he won't even need to seize Uchiha Kyon's body to master the power of the dragon himself!

Haha, although I was careless this time and suffered a lot at the hands of Uchiha Kyon, this little gain alone was worth it.

You know, for a scientist, this is equivalent to groping in endless darkness, and suddenly a morning star appears in the sky to guide the direction, which is of incomparable significance.

Uchiha Kyon didn't know that Orochimaru had so many thoughts flashing through his mind after he discovered that he was using the Curse Sealing Technique.

What he is thinking about now is how to completely kill Orochimaru to eliminate future troubles.

He stretched out his hands and tore Orochimaru's body in half before it completely liquefied.

But he still didn't dare to neglect it.

Orochimaru is so evil. If you were to say which ninja in the world is the hardest to kill, Orochimaru would rank second, and no one dares to rank first.

really.

Orochimaru's body, torn in half, turned into two pieces of shed snake skin.

Stab it!

There was a whistling sound in the air and a sharp gust of wind suddenly blew over.

Uchiha Qiong took a quick glance and saw that it was the remaining half of the dead black snake's body, with Orochimaru emerging from it.

Orochimaru opened his mouth and his tongue turned into a snake, which opened its mouth and spit out the Kusanagi sword again.

The Kusanagi sword shot out like a laser.

"Kusanagi Sword, Sora no Tachi!"

With this attack, even a tailed beast would be pierced if caught off guard.

Uchiha Qiong clapped his hands together.

Take the sword with your bare hands!
The Kusanagi sword shot out with such force that it forced Uchiha Kyon to retreat continuously and knocked down countless large trees.

The muscles in Uchiha Kyon's arms bulged high, his veins knotted, and he activated the Blue Dragon Seal and exerted force suddenly, knocking the Kusanagi sword off course.

Then he opened his mouth too.

Aiming at the staggering Orochimaru from a distance, the scorching heat like magma mixed with arcs of electricity gathered in his mouth.

"The roar of the Thunder Flame Dragon!!"

Uchiha Kyon roared like a dragon and spewed out a huge column of fire.

A circle of lightning surrounds the surface of the flame pillar, further increasing its speed and power.

This is no longer just heat breath, but an evolved version of heat breath, the roar of the Thunder Flame Dragon!
