Jiaolong and Qianyue quarreled a few words, and soon fell into the disadvantage, becoming more and more unconfident.

With its intelligence and eloquence, it is definitely not comparable to the cunning and treacherous Chizuki.

Moreover, Jiaolong could also see that Qianyue's racial bloodline was very extraordinary, and its strength was much higher than that in its heyday.

Its confidence became weaker and weaker, and it stopped arguing with Qianyue, and closed its mouth silently and did not speak.

Qianyue scolded it for a while before she was relieved, and when she saw that it was imprisoned in the ice lake and not free, she felt sympathy for the same illness and chatted with it.

The two of them exchanged for a while, only to find that what happened to each other was basically the same, they were both deprived of their life's work, and they were imprisoned for hundreds of years.

Jiaolong actually felt a little close to Qianyue, and had no intention of attacking Ji Tianxing again.

Qianyue comforted it a few words, and then flew back to Ji Tianxing's side.

It said to Ji Tianxing with a solemn expression: "Old Ji, no matter why this dragon appeared in the forbidden land of the Ji family, and no matter what secrets your ancestor has, you must release this dragon!"

"The Jiaolong clan of the East China Sea must not appear in the human world! otherwise, not only will the Ji family suffer a catastrophe in the future, but I am afraid that the Qingyun Kingdom will be destroyed under the wrath of the Jiaolong clan!"

Ji Tianxing suddenly frowned, shook his head again and again, and said, "Qianqian, you let me let it go?"

"The strength of this evil dragon is so strong, and it has been imprisoned here for a hundred years, and it hates the Ji family to the core. ”

"If I let it go, it will definitely destroy the Ji family and kill everyone!"

Qianyue thought for a moment and then had an idea, and a sly gleam flashed in her eyes.

"Hehe, Lao Ji, you are stupid! What does this little dragon crave the most? It is freedom!"

"As long as you are willing to let it go and give it freedom, it will definitely agree to your conditions and will not retaliate against the Ji family!"

Ji Tianxing was still frowning, and asked him suspiciously: "Qianqian, your method is unreliable!"

"Even if it promises me not to retaliate against the Ji family in exchange for freedom, who can guarantee that it will not go back?"

Qianyue hurriedly explained: "Old Ji, you don't know, the dragon clan attaches the most importance to promises and oaths. ”

"If you negotiate terms with the little dragon and let it swear in the name of the dragon god, it will never be able to betray the oath. ”

Ji Tianxing considered it silently, weighing the pros and cons and possible consequences in his heart.

Although he didn't know why the ancestor of the Ji family imprisoned the black dragon in Yanqing Lake.

But at present, it seems that this black dragon will not bring any help to the Ji family, but will be a great disaster.

After a while, he made up his mind, and nodded to Qianyue and said, "Okay, then I'll try to talk to it." ”

He walked out of the bamboo forest with the injury on his leg, came to the shore of the ice lake, and looked up at the dragon with a solemn face.

He said bluntly: "Jiaolong, I think we can make a deal." ”

The black dragon was stunned for a moment, glanced at Qianyue, and then asked in a deep voice, "What deal do you want to make with me?"

Ji Tianxing said with a calm face: "It is not my intention to fight with you and seize your azure crystal, I have my own hardships." ”

"And you have been imprisoned for a hundred years, not only have you lost your power, but you have also lost your freedom, and this is not your intention. ”

"So, you can trade your azure crystal for freedom!"

The black dragon's pupils suddenly constricted, and a thick look of surprise welled up in his eyes.

"You...... You mean, you're willing to let me out of here?!"

Ji Tianxing nodded and said, "Of course!"

"The cold iron chain tied to your tail is the best mysterious weapon forged by my Ji family's workshop, which is invasive and incorrosive for thousands of years. ”

"The lock mechanism and formation of the cold iron chain are the method of the Nine Doors Mystery Lock handed down by my Ji family, and I can help you open the chain. ”

The black dragon was suddenly a little excited, and his eyes flashed with a fine light.

"Boy, are you sure you're not lying to Benlong, are you really going to let me out of here?"

Ji Tianxing raised his eyebrows and asked rhetorically, "What's the matter?"

"Of course I want to leave!" the black dragon nodded hurriedly, and roared eagerly: "I have been imprisoned for more than a hundred years, and I want to escape from here all the time!"

"Although for as long as I can remember, I have been imprisoned in Yanqing Lake...... But I am a noble dragon, and I should soar through the nine heavens, crisscrossing the endless East China Sea!"

"I can't be trapped in this little puddle for the rest of my life!"

After a low roar, it looked down at Ji Tianxing with burning eyes, and asked in a deep voice: "Boy, if I give you the Azure Crystal, you will let me go?"

Ji Tianxing nodded again and said, "Yes, but I want you to swear in the name of the Dragon God that after you are free, you will never take revenge on the Ji family, let alone hurt me and the Ji family." ”

"No!" Black Jiaolong subconsciously shook his head and roared angrily: "Damn the Ji family, I have imprisoned Benlong for a hundred years, I hate to ...... the Ji family"

Halfway through the words, it suddenly saw Ji Tianxing's face turn cold, and a cold light surged in his eyes, so he immediately shut up.

It hesitated and struggled a little, and thought about it silently for a long time before finally making up its mind.

"For freedom...... Ben Long promised you!"

The cold light in Ji Tianxing's eyes dissipated at this time, "Then you swear in the name of the Dragon God now!"

The black dragon was still a little uneasy, and questioned him twice repeatedly.

After making sure that Ji Tianxing would not deceive it, it looked solemn and said in a solemn tone: "I swear in the name of the dragon god, if Ji Tianxing fulfills the promise to let me go and return me to freedom, I will not be guilty of the crimes committed by the Ji family, and I will never retaliate against the Ji family, let alone harm Ji Tianxing and the Ji family!"

The black dragon's voice was solemn and loud, revealing a solemn and majestic aura.

As its words fell, an invisible restraint descended from the darkness and burrowed into its body, haunting its dragon soul.

That's the oath bondage that comes from the oath of the dragon god!

If Ji Tianxing fulfills the contract, but it violates the oath, it will be invisibly bound and wipe out the dragon soul, and the soul will be scattered!

After swearing an oath, Jiaolong took off a black dragon scale from his forehead and handed it to Ji Tianxing.

Ji Tianxing didn't know what to do, and reached out to catch the swarthy dragon scales the size of a palm.

"Jiaolong, are you sure you didn't lie to me? The so-called Azure Crystal is your dragon scales?"

This palm-sized dragon scale, the whole body is pitch black and cold, it is not made of metal but exudes a metallic luster, and the weight is heavier than metal.

Black Jiaolong was questioned by Ji Tianxing, narrowed his eyes a little unpleasantly, and said in a cold tone: "This dragon has already sworn in the name of the dragon god, of course he won't lie to you!"

"If you inject the true element into the dragon scales, you will naturally understand!"

Ji Tianxing nodded in understanding, and a majestic true yuan poured out of his palm, injecting into the dark dragon scales.

Suddenly, the dragon scales shimmered with ice-blue brilliance and changed.

After just a few breaths, the swarthy dragon scale turned into a diamond-shaped, ice-blue crystal.
