In the depths of the underground of the Youyun Mountain Range, a flame kept burning, with the beating of the flames, the entire Youyun Mountain Range also underwent incomparably huge changes, a strange towering number of people on the periphery of the Youyun Mountain Range kept swaying, and a fierce wind swept the entire mountain range, like a silent roar!

Syllable!

A cracking sound sounded in front of Gu Dong, at this time, his face was covered with sweat, and the yuan power of his whole body was basically used, not only the rhizome rooted in the crystal wall under his continuous insistence was finally shattered, revealing a palm-sized hole below!

"It's finally open!" Ignoring Su Li Gudong's face full of ecstasy behind him, he felt the near-substantial Yuan Force that was constantly gushing out from below, making his originally weak body close to saturation at an extremely fast speed!

"What is this place......

Su Li, who had been standing behind Gu Dong, also felt the incomparable aura of Yuan Force in the air, and looked at Gu Dong with a shocked face.

"Your cultivation outside here can be regarded as a creation of you who recognize me as the Lord, and I will not force you wherever you go after taking me to finish things!"

Gu Dong pulled Xiao Qi to his shoulder, and the holy sword in his hand kept stirring in the palm-sized hole, with this gap and the sharpness of the holy sword, the hole began to grow larger.

Seeing the appearance of a hole that could already accommodate a person's body, Gu Dong jumped directly into it!

"Such a strong Yuan Force, I will be able to break through the middle stage of the fifth layer of True Martial Arts in less than a month of cultivation here! With the power of the late stage of the fifth layer of true martial arts, as long as I suppress the rules of heaven and earth a little and kill this person instantly, then I can regain my freedom! Su Li's face turned red, such a place can be said to be gathering the power of heaven and earth here, which is of great benefit to her cultivation.

After speaking, Su Li sat down cross-legged directly, the power of the martial domain on her body rioted, and the rich Yuan Force in the air continued to plunder, even the little leopard on her shoulder also closed its big eyes, and a flickering streamer continued to flow on it!

On the other hand, Gu Dong and Xiao Qi jumped directly into the hole, and their bodies fell rapidly before falling to the ground after a while.

Gu Dong's face was shocked, his right hand subconsciously stretched out, and he felt the soft silk threads touch his fingertips, and then kept pouring into his body from his hands!

Yuan Li is rich to the substance!

Just standing here, the endless Yuan Power kept surging into his body, and if he cultivated here, you can imagine the speed at which he cultivated.

Suppressing his excitement, Gu Dong did not sit down to practice for the first time, but spread out his divine thoughts and felt the fluctuations of the Yuan Force around him.

Call......

There was not a sound in the entire underground, but Yuan Li was like a breeze constantly brushing Gu Dong's cheeks, and with a breeze blowing, Gu Dong's eyes suddenly opened!

The figure turned into a streamer and went straight into the distance!

Whew!

As Gu Dong advanced, the Yuan Force in front of him became more intense, and he could even hear the sound of the Yuan Force wind growing stronger in his ears.

"This is it! This is Yuanli Spring!! Under Gu Dong's divine thoughts, the scene in front of him suddenly appeared in his eyes, and he saw that the yuan power was constantly gushing out of a cave, and all the yuan power in the entire dragon vein came from here!

Gu Dong stepped out of the cave, looked at it and stopped immediately after taking a few steps.

"The Yuan Force in this is like a knife, it can't go deep at all, without the cultivation of the fifth layer of True Martial Arts, even if I enter it, I'm afraid that I will be killed by this surging Yuan Force directly rushing into my body and exploding!"

Gu Dong hurriedly took two steps back, he also knew that he couldn't be greedy, he sat down cross-legged, Gu Dong's broken sword meridians were constantly agitating, like a giant dragon constantly absorbing the surrounding Yuan power!

Seeing that Gu Dong had started to cultivate, Xiao Qi also jumped up, his body turned into the body of a unicorn again, his claws kept waving in the air, and countless yuan forces were directly grabbed by him into pieces of substance and thrown into his mouth......

In the blink of an eye, half a month has passed, and a heavy breathing sound in the entire crypt beats rhythmically, this is Gu Dong, with his breath and breath, the cave is sometimes turbulent and sometimes calm, and the breath on his body is even more violent like the sea and sometimes calm like water, indescribably mysterious.

"There is still one step left to reach the fifth layer of True Martial Arts!" Gu Dong's eyes were closed, but his face was full of joy, such a speed was simply terrifying, but he knew that this was not only because of the rich Yuan power, but also because of the continuous compression of the broken sword meridians.

"As long as you reach the sixth layer of true martial arts, then I will ask the so-called great prince to exchange it with interest, if you reach the seventh layer of true martial arts, I don't mind letting the entire empire be replaced!" Gu Dong clenched his fists tightly, feeling the increasingly powerful power in his body, and for a while his heart was full of pride, in Gu Dong's eyes, if anyone was kind to him, he would repay it tenfold, and if anyone had hatred, he would have to repay it a hundred times!

At this time, what Gu Dong didn't know was that the outside empire was surging, and the academy was all closed, and a dynastic change was slowly brewing.

……

Bang!

Time flies, and in a blink of an eye, it has been a month since Gu Dong entered the underground, a loud bang sounded in his body, and the confinement of the fifth layer of Zhenwu was finally broken by him, at this moment he only felt that his whole body was like a dry well, and the full Yuan Force that was already in his body was like a small kettle turning into a river at this time, and countless Yuan Force was surging again, like a giant whale sucking water!

Gu Dong is now confident that if he is allowed to meet Su Li again, he can kill her with one punch without using the power of the Spirit Oath!

Call!

Just as he was about to settle down again, a faint groan suddenly came from within the Yuanli Tempest.

The body ejected, Gu Dong looked around vigilantly, such a cry came from this empty crypt, it must not be an ordinary creature, such a huge Yuan Force is an ordinary demon beast, and after training, I am afraid it is also a terrifying existence.

Hiss!

Two more voices came, Gu Dong's heart sank, and Shen Nian instantly captured the source of this sound when he was prepared, and looked squarely into the spring of Yuan Li.

After thinking about it again, Gu Dong decided to go into the cave, and with the cultivation of the fifth layer of Zhenwu, he was already able to go deep into the cave again at this time.

Step by step, the Yuan Force under his feet even condensed into a small stream of water......

As we went deeper, the sound of the moans became clearer and clearer.

Gu Dong's heart was like being struck by thunder, this is a dragon chanting!

No one knew this voice better than him, and it was not much different from the voice he had heard when he experienced the roar of the Inheritance Divine Power Fire Dragon!

"Is there really a true spirit born in this?"

Before Gu Dong could speak, the voice of the sword soul sounded in Gu Dong's mind in surprise.

"The dragon spirit is born in the dragon vein, which is bound to be extremely dangerous, and it may also be accompanied by endless opportunities......" the sword soul reminded Gu Dong.

Gu Dong nodded, and cautiously walked inward again.

The cave is getting more and more open......

"We have set up a formation to descend the dragon leyline, and we will finally have a harvest!" An excited voice was captured by Gu Dong's divine thoughts, making him stop again, there were other people in this leyline!

"Second prince, as long as this dragon soul has evolved and formed the soul of the empire, then the empire will be able to break away from the Dao Gate and seal the palace to become a place of its own! The empire will also be all yours, and you must return all the ancestors who were imprisoned in the Youyun Mountain Range, this is our agreement......" A hoarse voice came out.

"Haha, naturally, as long as I get the power of the empire, this is not a problem, now the empire is surging, and the prince has also begun to move, but the fortune of the empire will be held tightly in my hands! Haha......"

The man laughed wildly, watching the dragon-shaped Yuanli True Spirit that seemed to be locked in chains flick away.

Gu Dong hid in one place and only moved from beginning to end, his whole body breath was like a dead silence, just now the so-called second prince of the two of them had the cultivation of the late fifth layer of Zhenwu, Gu Dong was not afraid, but the demon clan who made a hoarse voice faintly said that the cultivation of the seventh layer of Zhenwu was far from being comparable to him.

You must know that the ninth layer of Zhenwu, reaching the sixth layer of Zhenwu is a hurdle, and the seventh layer of Zhenwu has crossed the so-called martial saints and others known to Gudong in the past, and I am afraid that he has comprehended the power of the rules.

Fortunately, after the two princes left, the breath of the demon clan slowly left.

After the two left, after a few hours, Gu Dong stood up cautiously, looking down with his eyes.

In front of him was a cliff-like position, and below him was a place where the circle was like a valley and concave down a hundred meters deep, and in the center of the valley jumped a huge dragon-shaped true spirit bound by countless red iron chains!

Painful groans continued to come out of the mouth of the true spirit, and Gu Dong had just stood up The sound of the true spirit's groaning became even louder, and the huge head also turned around with difficulty, staring at him.

Gu Dong felt pain in his huge eyes, struggled and asked for help......

Yes, it's for help.

"This true spirit must have felt its existence when it broke through in its cultivation, and this is why it kept moaning." This gaze made Gu Dong not arrive at all, and he couldn't help but think of it.

"Is this the dragon spirit?" Gu Dong kept observing this so-called dragon spirit, and there was a sense of intimacy in his heart.

"This is an insult to the dragons! Kill it! Even if the dragons die, they can't be used by the lowly human race! The voice of the sword soul suddenly roared in Gu Dong's mind!

Gu Dong's mind suddenly trembled, and his divine thoughts were beating uncontrollably, this was the first time that the sword soul was so angry.

"Could it be that you used to be a dragon too?" Gu Dong's heart trembled, and he said to the sword soul.

"No, I'm not a dragon! I don't deserve to be a dragon! Kill it!! The voice of the sword soul was crazy and full of pain, which shocked Gu Dong very much.

"Maybe we can save him......"

Gu Dong felt the anger of the guardian you, stared at the eyes that kept throwing him from below for help, and said to the sword soul.

"Save it?! The formation of the dragon descending leyline alone requires three people of the seventh layer of true martial arts, how can you solve it! It itself is the dragon vein Yuan Force Spirit, and it is trapped by these ten chains and can't leave at all......"

When the sword soul heard that Gu Dong actually wanted to save this dragon spirit, his tone was obviously better, but then he lowered his voice and said to Gu Dong.
