Time passed, and soon the dazzling auction came to a successful conclusion after the last piece of the auction was sold, and the dignitaries of the auction gradually departed with the glamorous closing fireworks.

Although there were some twists and turns in the auction process, Phantom Wolf still helped Aisen to successfully auction the seemingly worthless mysterious stone, for which he also used up all his pocket money, and it is impossible for him not to feel distressed, but he is also a heroic person, for the sake of friends, these losses are nothing.

After the auction ended, the three of them got up and went to the backstage of the auction to get the pitch-black stone that the "blood price" had won, and on the way to the backstage, the three of them were stopped by the sinister villain Lin Ce, who deliberately raised the price.

I saw that Lin Ce's face was full of ridicule, and the villain grinned proudly, "Yo, congratulations to Phantom Gongzi for auctioning this useless thing at a high price, I really admire it."

Under Lin Ce's taunt, the phantom little wolf, who was already upright and upright, suddenly clenched his fists, his muscles burst out, and he stared at the villain's proud Lin Ce angrily, as if he was about to make a move at any time.

At the same time, seeing that the situation was not right, Aisen, secretly said to the phantom little wolf, "Little wolf, this despicable villain is provoking you to do it, this auction is not allowed to do it in the auction hall by law, if you do it rashly, it is definitely us who will suffer, let's bear with it for a while, and when the class is compared, I will let this Lin Ce know the consequences of offending us."

Listening to what Aisen said, the angry phantom wolf also calmed down a lot, swept towards Lin Ce with a sharp gaze, and said proudly, "Dogs can't change eating, I didn't expect that after so many years, I still can't change your Lin family's bad mouth, today I let you, it's not that I'm afraid of you, I will make you kneel in front of you soon."

After saying that, the phantom wolf left here with Aisen and the others.

Seeing the phantom wolf and the others who were gradually moving away, Lin Ce's face was hideous, and he said in a deep voice, "Okay, you phantom wolf, I see how you, a ruined dog, made me kneel in front of you."

Then the three of them took out the dull black boulder from the backstage of the auction house, and if they didn't look closely, no one would be able to pay attention to the stone even if it was thrown into the rubble.

Looking at the ordinary stone, the little wolf's eyes were full of doubts, and he said to Aisen in confusion, "There is nothing unique about this stone, isn't it just a big ordinary stone, how can it attract you so much?"

"Hehe, the mountain people have their own tricks," Aisen smiled mysteriously, but secretly said to the Red Dragon King in the magic source, "Hey, Red Dragon, what the hell is this stone, it cost me 10,000 gold coins!"

"Isn't it just 10,000 gold coins, look at what makes you feel distressed, I don't know if you should say that you are short-sighted, or that you are obsessed with money, you must know that this stone can hide the origin bone of the ancient dragon clan, or a rare vertebrae" Seeing Aisen's distressed appearance, Chi Xiaolong secretly sneered at him with disdain.

"Isn't it just a bone, what's the big deal, can you add another demon spirit to me?" Eisen asked incomprehensibly.

"Demon Spirit, you kid is very greedy, if you can meet me, even if it is your luck, I didn't expect you to be whimsical here, but although the things in this stone are not as precious as the demon spirit, they are also extremely rare, you must know that this stone is the backbone of the instant dragon!" Speaking of this, Chi Xiaolong's eyes couldn't help but show surprise.

Seeing Chi Xiaolong's surprised appearance, Ai Sen asked puzzledly, "Instant Dragon, is it a dragon clan from the ancient period like you?"

"That's right, the Instant Dragon is a very special race in our dragon race, they don't have strong combat power, but they have been famous for their extremely fast speed, and the source of their rapid power is the speed wings derived from this vertebrae, there are also many ill-intentioned people who peep at their speed power, but once they are threatened, the vertebrae of the source of their power will be destroyed immediately, so that those with bad intentions have no chance to take advantage of it, and there is a complete Instant Dragon vertebrae in this stone!" Under Chi Xiaolong's explanation, Aisen also understood the extraordinariness of this stone, and at the same time was glad that no one had discovered its preciousness.

In addition to being delighted, Aisen also put this seemingly ordinary stone into the inventory, and then made it easy for the phantom wolf to return to the academy, and as soon as he arrived at the academy, Aisen couldn't wait to rush back to the dormitory, looking forward to the mystery in the stone.

In the middle of the night, everything fell into a deep sleep, but Eisen in the room was full of energy, looking at the dull black stone with bright eyes.

"Chi Xiaolong, what am I going to do next? you won't have to open a knife to catch this bone behind my back," Aisen, who was in the main hall, looked at the black stone at a loss, but for a moment he had some ridiculous imagination.

At the same time, I saw a small and delicate red dragon suspended in the air, holding its head high, and said majestically to Aisen, "It's okay, then dig out your bones directly, and directly replace them with this instant dragon's backbone."

"Hey, hey, you can't play really, I'm afraid that before the bones are connected, I'll go to the west" Aisen sighed in disbelief with a hint of panic in his eyes.

"Hahaha, of course I lied to you, if so, I'm afraid not many people would dare to take this keel" Seeing Aisen's panicked appearance, Chi Xiaolong couldn't help laughing out loud.

"But it's not so extreme, but it's not easy to absorb the Divine Speed Origin of this dragon bone, and it's also a test of your perseverance," after a short laugh, Chi Xiaolong retracted his smile and said to Aisen seriously.

Hearing Chi Xiaolong's words, Aisen's expression was also slightly condensed, his eyes were like torches, and he said proudly, "The avenue is long, if you don't have such perseverance, how can you achieve my future, come on!"

Seeing Aisen's free and easy meaning, Chi Xiaolong once again had an illusion of the newborn king of the young man in front of him, and secretly admitted the high-spirited young man in front of him in his heart.

Then Chi Xiaolong didn't have any worries, and drew a mysterious magic array in the air with his claws, enveloping the black boulder in it, and as time passed, the originally dull black boulder, under the summoning of the magic array, revealed its true appearance, only to see a crystal clear emerald green backbone appear in the boulder.

Immediately after, the emerald green backbone turned into a cloud of turquoise liquid under the refining of the magic array, and the liquid slowly moved towards Aisen's back under the control of the red dragon, at this time, the red dragon suddenly said in a loud voice, "Aisen, next I will integrate the divine speed origin in this spine into your spine, but you have to be prepared, then you will experience the pain of ten thousand insects devouring bones."

"Come on!" replied Eisen with a resolute look in his eyes and without the slightest hesitation.

Seeing that Ai Sen was so resolute, Chi Xiaolong did not hesitate, and directly introduced the turquoise liquid into Ai Sen's back.

At the moment when the turquoise liquid melted into his bone marrow, a terrifying pain came from his back, and in less than a moment, Aisen was in a cold sweat, his face was distorted, and he gritted his teeth to hold on, but despite this, he still didn't make a sound.
