The corner of Lu Tianlong's mouth, with his back to the entrance of the cave, curved with an evil intent.
He knew that the black dragon would definitely agree because it had no choice.
However, Lu Tianlong is also very clear about the little calculations that Heilong has in mind.
"Boy, come in, we will sign a soul contract now!"
The black dragon's voice sounded from the cave. It was no longer as strong as before, and even had a hint of flattery.
"good!"
Lu Tianlong did not hesitate and walked directly towards the entrance of the cave.
"Master Lu!"
The old wolf king and the wolf king were both shocked and subconsciously wanted to stop him. They didn't want Lu Tianlong to trust the black dragon so easily.
"It doesn't matter, you can just wait outside."
Lu Tianlong smiled at them and said, at least the black dragon would not do anything to him before he helped the black dragon free itself from its confinement.
The old wolf king gritted his teeth and said: "We will go in with you!"
Lu Tianlong's heart moved, and his impression of the old Wolf King and his son became better and better. After all, they must know that entering the dragon's lair this time is very risky.
However, he did not refuse and took the old wolf king and the wolf king directly into the cave.
"You're here, help me untie this damn chain quickly."
Seeing Lu Tianlong walking into the cave, the black dragon's eyes lit up, and its huge body twisted back and forth in the cave, obviously very excited.
It didn't even look at the Old Wolf King and Wolf King behind it, as if they were transparent.
"Sign the soul contract first."
Lu Tianlong said calmly.
"You..." Heilong seemed a little angry, and Lu Tianlong's expression was resolute, so he could only take a deep breath and nod.
"good!"
It shook its huge body, and terrifying energy fluctuations loomed on its body.
"I, the Black Dragon of the Imperial Realm, have reached a soul contract with Lu Tianlong today. From today on, we must obey his orders, otherwise we will be destroyed!"
A series of obscure French words came from the black dragon's mouth.
For example, the black dragon that has reached the imperial realm must know how to sign a soul contract.
I saw a faint black line wandering out of the black dragon's body, quickly coming towards Lu Tianlong, and then seeping into Lu Tianlong's mind.
A strange feeling formed between Lu Tianlong and Black Dragon.
"Okay, can you help me untie this damn chain now?"
Black Dragon urged.
"Can."
Lu Tianlong nodded and slowly walked forward.
He let the black dragon land from mid-air, crawled directly to the ground, and then took out the Pluto Emperor's scepter.
Just like when he liberated the old Wolf King before, he used the Hades' aura on the Hades' scepter to directly break the chains.
"alright?"
Seeing the chains that imprisoned him break, the black dragon seemed a little unbelievable.
It stared at it with wide eyes for more than ten seconds, then suddenly let out a shocking dragon roar, and instantly jumped into the air, so excited that it didn't know what to do.
"Oh my god, I actually got out of trouble."
"That damn chain has imprisoned me for so many years, and now I'm finally free, I'm finally free!"
"From now on, I can go to heaven and earth freely, and no one can imprison me anymore!"
"Roar!"
With a dragon roar, the black dragon suddenly rose into the sky and rushed out of the cave entrance.
"Ho ho ho!"
There were waves of energy fluctuations and the roar of black dragons coming from outside. The ground was shaking and the screams of many wild wolves could be vaguely heard.
"Master Lu..." The old wolf king looked at Lu Tianlong with some worry.
The Black Dragon had been holding it in for too long, and now he just rushed out and started wreaking havoc. He must have accidentally injured many members of the wolf clan.
"Let's go out and take a look."
Lu Tianlong looked indifferent and walked towards the outside of the cave.
When he took the old wolf king and the wolf king out, he happened to see the black dragon wreaking havoc.
It released waves of terrifying black aura, like layers of tornadoes, sweeping directly in all directions.
The sky collapsed and the earth shattered wherever it passed, and many members of the wolf clan who had no time to escape were directly involved in it, instantly shattered, and their souls were immediately scattered.
That is the Black Dragon of the Imperial Realm. How could those wolf clan members of the Void or Holy Realm resist it! "Black Dragon!"
Lu Tianlong suddenly shouted loudly.
"Roar!"
Hearing the sound, the black dragon roared, its huge body suddenly turned around, and swooped down towards Lu Tianlong with lightning speed.
When it swooped down, it carried violent pressure, making Lu Tianlong below feel like the sky was falling.
But he gritted his teeth and stared at the black dragon expressionlessly.
"Master Lu, be careful!"
The old wolf king behind him spoke hastily. If the black dragon really rushed down, Lu Tianlong would probably be smashed into pieces! But in the end, the black dragon stopped ten meters away from Lu Tianlong.
Its huge body twisted slowly, and a pair of lantern-like eyes stared at Lu Tianlong, with a ferocious and gloomy look.
"Black Dragon, you have signed a soul contract with me, and now you must obey my orders."
Lu Tianlong said calmly.
"Follow your orders?
Ha ha ha ha!"
Black Dragon laughed wildly as if he had heard the funniest joke.
"Boy, you are really an idiot."
"I am a powerful imperial black dragon, and you are just a stupid and weak guy. You actually want me to obey your orders?"
Lu Tianlong raised his eyebrows slightly and said, "Do you want to regret it?"
"Repent?
No no no no!"
The black dragon smiled ferociously, "I don't want to go back on my word, but you idiot, do you really think you can control me by signing a soul contract with me?"
"You are wrong. With your weak strength, the soul contract we signed has no effect at all, and you can't control me at all!"
"Yeah?"
Lu Tianlong's lips curled into a sneer.
"It seems that you still hate me because of what happened before, so not only do you not acknowledge the soul contract now, or do you also want to kill me?"
"Congratulations, you got it!"
The black dragon's expression became more and more ferocious, his eyes fixed on Lu Tianlong, without concealing his murderous intent.
"You bastard, you robbed me of the three fruits I had been waiting for so hard."
"You actually threatened and lured me later, asking me to protect your stupid grandpa?
When did my proud black dragon clan ever receive such a drive?"
"Boy, hand over those three fruits, and then hand over the scepter you just had. Maybe I can keep your body intact."
"Otherwise, with just one move from me, all of you can be completely wiped out!"
The black dragon completely broke his skin. Sure enough, it was just as Lu Tianlong thought before, and it was just like the black dragons he had seen before, cunning and cruel in nature.
It has been deceiving Lu Tianlong from the beginning, and now it finally reveals its true colors!
