Naruto: Starting With Three Tomoe Sharingan, Girlfriend Kushina

This time, Ryun used his Sharingan to control it but specifically allowed it the ability to speak.

"Wait, wait. Let's talk this through. As long as you don't attack, we can cooperate in any way you want." The black dragon spoke in a panicked hurry.

It was afraid that if it spoke too late, it would immediately get stabbed by that blade. If it ended up like before where it couldn't even beg for mercy, that would truly be miserable.

"I'm asking you how you suddenly transformed from a serpent into a dragon." Ryun frowned as he spoke.

Seeing his expression, the black dragon instantly shivered in fear.

"I, I just awakened my bloodline inheritance power. I completed my evolution and transformation in Ryūchi Cave."

The black dragon answered honestly, not daring to hide anything. It had just completed its second evolution and was at its peak. If it were to be casually stabbed to death by this little brat while in a weakened state, that would be way too damn humiliating.

"There aren't many serpent-dragons like you in Ryūchi Cave, right." Ryun suddenly asked this question.

When he watched the anime before, he hadn't seen any dragon-like serpents in Ryūchi Cave. There was only Manda and the White Snake Sage who had dragon horns, somewhat resembling dragons.

Oh right, there was also the second-generation serpent-dragon Manda II, which Orochimaru cultivated using Manda's cells. But that thing was a product of science and didn't belong to the serpents of Ryūchi Cave.

"In all of Ryūchi Cave, only I have completed the second evolution. Only I am the true dragon."

The black dragon's voice was full of pride and arrogance.

"Hmph. Do you even know what a true dragon is? You're just a mere serpent-dragon, still far from being a true dragon in the real sense." Ryun coldly snorted, somewhat disdainful.

"Bastard, how could a little human brat like you know more than us of Ryūchi Cave? What serpent-dragon? This lord is a black dragon, a true dragon." The black dragon angrily roared.

Being told it wasn't a dragon felt like an insult to it.

"Of course I know more about dragons than you. I am the Descendant of the Dragon"

Ryun calmly stared at it, his serious expression completely unlike someone lying.

"Wh, what nonsense is this?" The black dragon widened its eyes, full of doubt.

"A little human brat calling himself a Descendant of the Dragon. You think I'd believe you?"

"Believe it or not, that's up to you." Ryun replied indifferently.

"Hmph, I knew you were just spouting nonsense, lying through your teeth. You can't even recognize a true dragon yet dare to question me."

"Shut up."

Ryun suddenly shouted with a dark expression, cutting off the black dragon's words.

"A serpent is just a serpent. You don't understand what a true dragon is at all. If you knew what a true dragon was, you wouldn't be so arrogant as to compare yourself to one."

"A dragon can be large or small, rise or hide. When large, it summons clouds and mist, calls wind and rain, controls lightning and thunder. When small, it conceals its form, leaving no trace, invisible to ordinary eyes.

When it rises, it soars between the heavens, roaming freely across the world. When it hides, it lurks within the waves, exerting its might across the seas."

"A true dragon's roar can shake the heavens and earth. A casual swipe of its tail or claws can split mountains and sever rivers. Tell me, which of these abilities do you possess now?"

Ryun coldly interrogated.

"You only have the shape of a dragon. If you called yourself a serpent-dragon, I wouldn't bother arguing. But you call yourself a true dragon? That's just shameless arrogance."

"Right now, you're just a three-clawed serpent-dragon. Only when you grow to five claws will you have the right to call yourself a true dragon. Understand, idiot."

At this moment, the black dragon was completely stunned.

It had originally thought this little human brat calling himself a 'Descendant of the Dragon' was just boasting. But now, after hearing this speech, even the black dragon couldn't help but believe the truth in these words.

The ancestors of Ryūchi Cave had indeed mentioned true dragons before.

They were beings that serpents could never hope to reach.

The founder of Ryūchi Cave spent its entire life unable to attain the height of a true dragon, forever stuck at four claws.

For Ryun to mention the five claws of a true dragon meant his words weren't nonsense. This might be someone who understood dragons better than the serpents of Ryūchi Cave.

No, he might even understand dragons better than anyone in the ninja world. Maybe he really was a 'Descendant of the Dragon'.

"You, just who are you."

At this moment, the black dragon no longer dared to call itself a true dragon. It also no longer felt insulted by Ryun calling it a serpent-dragon.

It already knew about the five claws of a true dragon. But since it was the only serpent in Ryūchi Cave to reach the level of a dragon, it had the confidence to boast about being a true dragon.

It never expected that right after transforming, its boasting would be instantly slapped down.

And now it was at the mercy of others.

"No rush. Only after you make your choice will you have the right to ask who I am." Ryun smiled as he spoke.

"What choice?" The black dragon hurriedly asked.

"Submit, or die."

Ryun stared at it calmly. If he didn't get the answer he wanted, he wouldn't hesitate to stab it to death.

After all, no matter how good a serpent-dragon was, if it wasn't useful to him, it was just a beast. A beast that tried to bite him didn't need to be kept.

Plus, this thing looked like it was full of treasures. If he could bring its body to Orochimaru-sensei, maybe he could research something good out of it.

"I, I submit."

In the end, the black dragon could only bow its head in surrender.

It had no choice. If it didn't submit, it would be a blue blade in and a red blade out.

Looking at Ryun's expression, he didn't seem like someone who would joke around with it.

Before, as a serpent, it didn't even have the right to beg for mercy. Only after becoming a dragon did it gain the right to speak.

"Swear it. Swear by the name of Ryūchi Cave. Swear by the name of the true dragon. Swear by the lightning tribulation." Ryun smiled as he spoke.

This thing even ate its own kind. Its rebelliousness was practically written on its forehead. Ryun didn't really believe it would be obedient.

"What. You."

The black dragon widened its eyes, seeming angry. But under his oppressive might, it ultimately swore the oath exactly as Ryun demanded.

For a creature like it that needed to undergo tribulations, swearing an oath to be struck by lightning was the most taboo. Even more taboo was breaking such an oath.

This time, it had truly submitted.

Actually, thinking about it carefully, Ryun called himself a 'Descendant of the Dragon'. So submitting to a Descendant of the Dragon wasn't so bad. After all, Ryūchi Cave forming summoning contracts with humans was somewhat similar in meaning.

Most importantly, the black dragon wanted to learn more about the secrets of true dragons from him. That was why it submitted so readily.

"Good."

Ryun laughed heartily and immediately released the genjutsu binding, allowing the black dragon's body to regain freedom.

"This is the power of the Sharingan, right."

The black dragon wasn't some ignorant serpent. It clearly knew about these red eyes. It just never expected this child's ocular power to be so strong. That overwhelming mental binding force was simply unreasonable.
