I take the system through the bucket

In the empty space, in the void thunder pool, the silver-haired girl sitting cross-legged on the golden dragon's head suddenly frowned.

She slowly opened her eyes, and the golden and silver thunder flashed in her eyes. She got up, and the gorgeous gold and silver robe wrapped her around her, and a powerful thunder burst out of her body.

The terrifying power caused the surrounding golden thunders to flicker continuously. As the thunder danced, the entire void thunder pool began to boil, and it slowly stopped after a few minutes.

The girl let out a breath of turbid air slowly, bathed in the thunder, looked at the huge golden thunder dragon, and said softly: "Don't worry, I will definitely keep my promise and find a way to take you out."

The huge eyes of the golden thunder dragon looked at the girl, and then nodded slightly.

The thunder continued to fall, and amidst the roar of the thunder, the girl's figure suddenly moved, turning into a silver giant dragon that quickly shuttled through the void, and quickly approached Beilong Island.

The girl was Gu Yue. That time, after she entered the Void Thunder Pond, because she was very good at using the power of thunder, this place was indeed very suitable for her cultivation.

But after practicing for a while, she suddenly felt someone calling her.

She wasn't so curious, this place looked extremely dangerous at first glance, and wandering around would be a dead end, but, as time passed, the thunder power in her body became more and more abundant, and the voice became more and more clear.

Finally, she accidentally stepped into the golden thunder pool, and then saw the golden thunder dragon that kept calling her.

The thunder dragon is not a dragon, it is the spirit of thunder, and it is also the core of the entire void thunder pool, but because of some wishes, it did not give birth to a complete spiritual wisdom, nor can it leave this place.

And as time passed, it instinctively couldn't bear this kind of loneliness, and at this moment, Gu Yue appeared.

I don't know why, or it could be said that the strengths of the two are very compatible, the communication happened, and the contract was reached.Thunder Dragon is responsible for helping Gu Yue improve his strength, and Gu Yue is responsible for helping this golden dragon to obtain complete spiritual intelligence one day when his ability is reached, and then leave this place.

It was a very fair transaction, everyone got what they needed, and the following training process went quite smoothly. The thunder dragon is not a dragon, but it is also a dragon, and Gu Yue is already very good at using the power of thunder, so the two sides are very compatible.

After that, Gu Yue fell into a long-term retreat, and when Xiao Heng came to this retreat, she felt it, but she didn't wake up, and now, her strength has reached a special stage, as if I slept for too long, couldn't fall asleep, and needed to go out for a walk.

Moreover, after practicing here for too long, her body has developed some resistance, and if she continues to stay, her cultivation speed will continue to slow down, and it will only become slower and slower.

And just at this time, in the ring, the purple jade tablet flickered slightly... Last time, she had just been in retreat for a short time, and she didn't have the energy to pay attention to the outside world, and now, it's time to go out.

And after retreating for such a long time, her strength is destined to be unexpected.

The golden dragon watched the figure quickly disappear from sight, climbed down again, closed its eyes, and continued to sleep. It was Thunder Spirit, and it was also the core of this void thunder pool.

To be precise, it is Jiuxuan Jinlei itself, a power that is not inferior to the Jinglian Demon Fire. It is of the same level as the Jinglian Demon Fire, but it has not been able to condense complete spiritual wisdom, and it is also It can't leave here, otherwise, its strength may be stronger than Jinglian Yaohuo.

As for Gu Yue's departure, its incomplete intelligence didn't have much thought. It just followed its instinct and felt that the creature could help itself, and then reached a cooperation with her. As for the others, with its current I can't think of so much in my mind.

In the empty space, North Dragon Island...

Outside Beilong Island, many figures looked at the big formation surrounded by the blood-colored formation with extremely gloomy expressions.

"Dragon Transformation Formation, this damn guy, the beast of the North Dragon King, how dare he use such a formation, he is looking for death...!" Looking at the bloody North Dragon Island, an elder cursed angrily.

"Dragon Transformation Demon Formation, the Jinda that was destroyed thousands of years ago, this damn guy..."

"Damn it, this bastard, the Northern Dragon King, will always be spurned by the Taixu ancient dragon clan...!"

Everyone cursed angrily, looking at the blood-stained formation with gloomy faces, but they didn't dare to approach it.

The Dragon Transformation Magic Array, a forbidden technique of the Taixu Ancient Dragon Clan, was created by a senior of the Taixu Ancient Dragon Clan. Its function is to shatter all the life in the formation, and then turn it into energy to nourish the caster.

In other words, in this large formation, except for the caster, that is, the formation eye, all life will die, and then be turned into nourishment to enhance the power of the formation eye.

And because it was too cruel, this formation has been banned and finally destroyed, but the North Dragon King, after his defeat from Donglong Island, he found out this formation that should have been destroyed again, and then directly Displayed on Beilong Island.

Then, he directly used this formation to swallow the West Dragon King and the South Dragon King, and then he coaxed the remaining elites of West Dragon Island and South Dragon Island to gather at North Dragon Island, and then used the big formation to swallow them all.

And after Zi Yan led people to attack Beilong Island, she also discovered this situation, and in order to save the remaining Taixu ancient dragons, Zi Yan tried her best to send some Taixu ancient dragons out of the big formation, and she herself, was left in the big formation.

"boom…!"

There was a loud noise, and Zi Yan held the dragon-slaying sword in her hand, and stabbed at the monster with a sword, and the monster did not show any weakness, she slapped out with a palm, and a powerful force burst out, the terrifying power made Zi Yan unable to bear it, directly retreat.

The two have fought against each other several times, and in this large formation, Zi Yan is not an opponent when facing the greatly increased strength of the Northern Dragon King, and the Dragon Slayer Sword is also suppressed by that powerful strength. To be precise, it is Corrupted by the blood that belonged to the Taixu Ancient Dragon Clan.

However, even so, relying on the dragon-slaying sword, Zi Yan still supported it. However, if this continues, she may not be able to hold on for long.

Flying Ziyan with one palm, powerful energy ripples continued to spread, blood qi swayed, and the terrifying coercion made the Great Elder of Donglong Island outside the big formation feel a little blood turbulence in his body.

"Hahaha...Little girl, the power of the Dragon Transformation Demon Formation is all forced by you! Now, it's up to you to try its power yourself."

"When I devour you, I will definitely become the most powerful dragon emperor in the history of the Taixu ancient dragon clan, and the entire continent will crawl at the feet of this emperor... Hahaha...!"

Pushing Zi Yan back with one palm, looking at the embarrassed Zi Yan, the North Dragon King laughed wildly, sensing the terrifying power flowing in his body, this feeling fascinated him, at this moment, even if it was the Dragon Slaying Sword, he did not pay attention to it inside.

With a slight movement of his figure, the surrounding space trembled continuously, releasing power, and the entire Beilong Island trembled.

Zi Yan looked at the ugly Northern Dragon King, her breathing was a little short, blood fell down the Dragon Slaying Sword, the Northern Dragon King who could be injured by the Dragon Slaying Sword.

I saw that the wound healed quickly as the blood rolled.

At this moment, Zi Yan's breath was a little sluggish, and some blood was stained on her body. Some of these blood belonged to the Northern Dragon King, and some belonged to her.

Looking at the Northern Dragon King, Zi Yan's eyes were cold.

The Northern Dragon King at this moment is a complete lunatic, with blood surging all over his body, dyeing him into a blood man, half human, half dragon, human nature, but with many characteristics of a dragon.

The most disgusting thing was that on the neck of the North Dragon King, in the surging blood, three heads grew on one body like sarcoids. It was the West Dragon King, the North Dragon King and the South Dragon King.

However, at this moment, there is no soul in the eyes of the South Dragon King and the West Dragon King. The reason why it appears is only because of some changes that occurred when the North Dragon King devoured the two of them.

Blood was surging, and the North Dragon King looked at Zi Yan, smiling strangely on three faces.

"Hahaha... This king has already experienced the power of the dragon-slaying sword. Now, let me show you how powerful this dragon-slaying sword is...!"

As the words fell, the blood in the hands of the North Dragon King rolled, and a big sword suddenly formed, but, compared to the sword in Ziyan's hand that exudes sacred majesty, the one in his hand, from the hilt to the blade, has nothing. It revealed the cold breath of blood.

"Dragon-slaying sword, a beast like you that devours people is worthy of summoning the dragon-slaying sword, but it's just your own fantasy, looking for a dead end!" Zi Yan said coldly, holding the dragon-slaying sword tightly in her hand, and the phoenix wings behind her back suddenly moved, and she slashed at the North Dragon King. .

"Are you asking for your own death? It doesn't count if you say it." The North Dragon King roared, opening three mouths at the same time. His appearance was a little more terrifying than a monster.

"Clang...!"

Two dragon-slaying swords collided suddenly, one solemn and solemn, the other bloody and cold. When they collided together, the terrifying energy burst out suddenly, and the sword gang erupted continuously.

The two flipped the dragon-slaying sword and collided quickly. In the blink of an eye, they fought dozens of times.

"Clang...!"

A metal roar resounded through the sky again, and the aftermath of terrifying energy shredded the space and continued to spread.

With a sword falling, Zi Yan was forced to retreat continuously by the powerful force, and there was another wound on her arm.

The Northern Dragon King also had many wounds on his body, but the blood kept rolling on his body, and the wounds quickly disappeared.

The two fought again, even though Zi Yan had the body of a dragon and a phoenix and possessed the purest dragon-slaying sword, she was still firmly suppressed by the Northern Dragon King. Although the Northern Dragon King had become a monster, his strength had also been greatly improved .

For a while, even Zi Yan was no match for him.

And just when the two collided again, a golden thunder suddenly fell from the sky.

"Boom...!"

With a loud noise, the golden thunder swept away thousands of meters of blood, and the entire Beilong Island was shocked.

"Who is it? Get out of this king, what kind of skill is it to play tricks...!" The Northern Dragon King was blown away by the golden thunder, leaving several wounds on his body. The stinging pain still existed, and the painful feeling also made him fearful for a moment.
