I think back then, during the Burning Heaven Holy Ranking Competition in the Nine Heavens of Burning Heaven Realm, Dongfang Xue learned a skill through an Ascension Order.
That skill is a truly taboo skill!
Its name is: Great Sacrifice Technique!
This technique can be used to exchange for powerful power by sacrificing the user's life span, essence and blood, or even part of the body, and can achieve things that the user alone cannot do.
In order to help Dongfang Xue, Gu Xuan also learned this "Great Sacrifice Technique" from her.
However, Guxuan is rarely used.
The main reason is that when Gu Xuan used this technique in the holy realm to help Dongfang Xue cheat and improve his realm, he angered the true world of heaven and sealed this technique.
Of course, this seal is only limited to the Burning Heaven Realm.
When we reach the true world, the so-called seal is no longer the same as nothing.
Secondly, this technique is too powerful, too easy to use, and too weird.
Its essence is to exchange for power through some kind of sacrifice, which can be regarded as an exchange contract.
There is no free lunch in the world, and sacrificing yourself to some extent in exchange for strength is not a long-term solution after all.
Once you get used to it, you will easily become addicted. If you encounter a strong enemy in the future, you will inevitably rely on this technique. By then, it will be too late to regret it.
To put it simply, this is a method of drinking poison to quench thirst.
Gu Xuan will never use it unless absolutely necessary.
But now, it's time to do it as a last resort.
The enemy is the way of heaven!
Ho ho ho!
The head of the Heavenly Punishment Thunder Dragon has already penetrated through the palace gate.
At this moment, Gu Xuan had already walked to the door.
"You'd better get out!"
He gently raised his right hand and placed it on the head of the Heavenly Punishment Thunder Dragon.
Violent power surged out from his right hand.
"court death!"
Somewhere in the distant space and time, looking at this strange scene in the Xuanguang Mirror, Zhenjie Tiandao snorted coldly.
Gu Xuan dared to directly reach out and touch the Heavenly Punishment Thunder Dragon. This was no different from sending him to death.
But, the next moment, Zhenjie Tiandao was stunned.
"How...possible?"
In the entrance mirror, in the imagination, the scene where the Heavenly Punishment Thunder Dragon exploded instantly, blowing Gu Xuan into powder, did not appear.
The Heavenly Punishment Thunder Dragon was as if it had been immobilized by a immobilizing spell. Not only was it motionless, but the energy fluctuations on its body also stopped.
Gu Xuan slowly opened his mouth and spoke the truth.
"I will live five hundred thousand years in exchange for your destruction!
Great Sacrifice Technique!"
More violent energy burst out from Gu Xuan's body and condensed on his right hand.
A looming magic circle seemed to appear and disappear at Gu Xuan's feet.
Countless mysterious runes appeared around Gu Xuan's body, drawing mysterious trajectories in the air.
At this moment, Gu Xuan seemed to have transcended a god and demon from eternity!
Say it, follow it!
Violent energy surged from Gu Xuan's right hand towards the Heavenly Punishment Thunder Dragon, and sank into its body without any hindrance.
The huge body of the Heavenly Punishment Thunder Dragon disappeared from the beginning to the end out of thin air at a speed visible to the naked eye!
No one could have imagined that things would turn out so unexpectedly.
A Heavenly Punishment Thunder Dragon that could kill any elementary Saint Lord just disappeared out of thin air without any reason.
Even, there is not even a little bit of energy fluctuation left, as if it had never appeared.
In fact, even the Heaven Punishment Tribulation Cloud didn't react and forgot to continue condensing the third Heaven Punishment Thunder Dragon.
An irresistible feeling of weakness came over him, making Gu Xuan feel like he wanted to fall into a deep sleep. Even his eyelids drooped involuntarily.
Sacrificing half a million years of life at once is not fun.
His longevity, after taking two fruits of the sacred tree, has already exceeded that of many saints, reaching 1.5 million years!
The lifespan of an ordinary first-level Saint Lord is only one million years!
Generally, the lifespan of a half-step saint is only 600,000 years.
As for Gu Xuan, his lifespan is already twice as long as that of a strong person in the same realm, and is over 300,000 years old. This is unprecedented in the Three Thousand Worlds.
Unfortunately, this time, in order to perform the "Great Sacrifice Technique", I lost one-third of my life span.
Even though his remaining million years of life were still impressive, losing half a million years of life at once still made him feel physically and mentally exhausted.
Gu Xuan quickly bit the tip of his tongue, a sharp pain hit him, and he finally regained consciousness.
"The teleportation array has begun to operate normally, let's leave quickly!"
Yun Xi's voice came from above the teleportation array.
When Gu Xuan heard this, his spirit was lifted again.
"Great, let's go before the Heavenly Dao of the Real Realm reacts!"
Gu Xuan suddenly turned around and took one step back to the teleportation array.
Suddenly, a dazzling light lit up from above the teleportation array.
The majestic power of space suddenly surged around, and even the entire palace began to distort visibly to the naked eye.
In the Xuanguang Mirror of the True Realm of Heaven, the image of Guxuan can no longer be seen.
All that can be seen is a palace that is beginning to distort.
It wasn't until this moment that Zhenjie Tiandao reacted.
"No! Gu Xuan cannot be allowed to leave the true world!
If he leaves safely, where will my face be left?"
The true world of heaven was extremely angry.
I am the Heavenly Dao of my own world, and I do not hesitate to take advantage of loopholes in the rules to kill Gu Xuan. If I fail in the end, what will the Heavenly Dao of other worlds think of me?
Not to mention other worlds, but what would the Lord of the True World think of himself?
I'm afraid, her teeth will fall off due to laughter, right?
"I would rather destroy the ancient teleportation array to the Burning Heaven Realm than prevent you from leaving!
Even if I try to get hurt, I will kill you!
Die, Gu Xuan!"
The true world of heaven roars endlessly.
He controlled the Heavenly Punishment Tribulation Cloud, turned it into a mountain flashing with black thunder and lightning, and directly bombarded the palace where Gu Xuan was!
Boom!
Wherever the mountains pass, space is shattered.
The power of this smash can be said to destroy the world!
The true world of heaven wants to destroy the palace, the teleportation array, and Gu Xuan together!
It is a pity that the speed of the true world of heaven is a little slower after all.
Just when the mountain was about to fall, the palace below disappeared without a trace in a burst of space fluctuations.
Boom!
The Jie Yun Mountains crashed into an open space, causing the earth to shake.
A moment later, the palace that disappeared out of thin air reappeared amid a burst of space fluctuations, as if it had never disappeared.
The ancient secret realm has returned to peace.
"Hahaha, how about the person I like?"
A burst of extremely flamboyant, yet clear and melodious laughter suddenly came from the entrance mirror in front of Tiandao.
The figure of the Lord of the True World covering his mouth and laughing appeared from the Xuanguang Mirror.
Her face was full of pride.
Zhenjie Tiandao clenched his fist, as if he was holding Gu Xuan in his hand and he was going to crush Gu Xuan to death.
"Then even if Gu Xuan can survive today, so what?
I have already ordered the archangel to go to the Burning Heaven Realm to give him a big gift!
