In the Eighteen Purgatory, the purple liquid was mixed with a trace of cyan aura, this was the legendary 'Azure Qi', only a trace was needed, it was comparable to a large piece of immortal crystal.

Looking at the strange combination in front of him, Lu Zheng had a feeling of surprise, the World Tree had opened the passage of the fairy realm, and it could continuously absorb the immortal aura for so long, and the immortal aura could be used to urge the eighteen purgatory, wouldn't it be invincible?

However, Lu Zheng soon understood that even if the World Tree kept absorbing the immortal aura day and night, the immortal aura provided every day could only completely trigger the Eighteen Purgatory.

This is still a little insufficient for Lu Zheng.

Suddenly, Lu Zheng realized that he had made a mistake, which made him laugh and cry.

Generally speaking, among the immortal weapons, there is a thunder pool as a power source to provide energy, but it is a waste to directly use the immortal spirit qi yourself.

Although this will be more powerful, the sustainability is not as good as that of Lei Chi.

However, it is not difficult at all, after all, the Thunder Hell in the Eighteen Purgatory, which is transformed by the Gate of Ten Thousand Thunder, can absorb the power of the Thunder World.

It's just an instant, in the thunder hell, there is rolling thunder, and if you move at will, it is the power of rage to the extreme.

The current Eighteen Purgatory, that is, the World Tree absorbs the immortal aura as the power of the Gate of Ten Thousand Thunder, and the Gate of Ten Thousand Thunder can open the Great World of Thunder and absorb the power of the violent thunder in it.

"In this way, I can urge the Eighteen Purgatory as many as five times a day!" Lu Zheng thought about it, as long as he accumulated a few days of energy, who could be his opponent below the Five Tribulation Void Immortals?

"Boom!" Just when Lu Zheng was excited, suddenly, the entire Eighteen Purgatory was hit hard, and began to shake violently, and the rules in it began to break inch by inch, and even the solid world barrier seemed to be about to shatter, and a destructive force permeated the Eighteen Purgatory.

Brush, at this critical moment, the World Tree moved, and countless branches stretched out, merging with the entire Eighteen Purgatory, and finally supporting the entire world, making the world solid and immortal.

Lu Zheng's heart shook wildly, knowing that he had neglected a major event.

The true immortal head of the letter in the Immortal Crystal Mountain!

Now that such a long time has passed, the true immortal head must have awakened, and the result of this is likely to be catastrophic.

Thinking of this, Lu Zheng had a big head, even when he was the Heaven Devouring Demon Emperor, Lu Zheng had never encountered the head of a living true immortal.

Coming out of the Eighteen Purgatory, the Eighteen Purgatory turned into a halo, firmly guarding Lu Zheng's body, and Lu Zheng saw the head of the true immortal not far away roaring, as if it was roaring something.

The clouds were churning in the sky, and a galaxy from an unknown number of billions of miles away was flickering violently, and then it turned dim in an instant and completely turned into ashes.

The energy of the stars converged into a long river, and all of them were submerged into the mouth of this true immortal head, and suddenly, the breath of this true immortal became more powerful, and it seemed that if it moved at will, it was the power to destroy the heavens and the earth.

Lu Zheng only saw a huge head flying up, the whole head was bigger than the previous Xianjing Mountain, bigger and growing, in the end, just a pair of eyes, comparable to the sun, moon and stars, every strand of his hair can cut the void, just floating there, it makes Lu Zheng feel a little depressed breathing.

What a horrible spectacle this is? His hair can rip an ancient star just by moving in the wind!

Suddenly, Lu Zheng felt that the space around him was imprisoned, this was not a simple rule imprisonment, but in an instant, the density of the surrounding space increased by hundreds of times, reaching an unbelievable level, almost becoming a spatial crystal, Lu Zheng was sealed in the crystal, unable to move.

"Now...... What era is it?" The ancient true immortal's head shrank rapidly, making such a sound, and at the same time, the stars of another starry sky in the sky began to twinkle, sprinkling starlight, and condensing into a powerful body under the skull.

This is actually very normal, the Three Tribulations Void Immortals can be reborn with blood, which is naturally easier for true immortals, but it needs to consume a lot of essence.

Now this true immortal head directly devours the power of the starry sky, which is simply the creation of heaven and earth, to support himself, this method is simply against the sky!

Then, a chaos-colored robe appeared on the true immortal's body, and he walked over step by step, with each step, his body shrank by a point, and by the time he arrived in front of Lu Zheng, he had already become an ordinary teenager.

His hair was casually draped, his eyebrows were like swords, and his eyes were like stars, just standing there, as if he was the center of the heavens and all worlds, and even the power of a great world could not compare to him!

"Now is not the time of the ages, but the time of the heavens and all the worlds. Lu Zheng opened his mouth and said, although this guy is indeed terrifying, but it is a little different from what Lu Zheng imagined, after being sealed for countless years, he didn't go crazy when he came out, as if he had slept and woke up.

"Heavens and Ten Thousand Worlds......" The young man groaned, and then all kinds of mysterious runes flickered in his eyes, as if there were phantoms flickering in his eyes.

"It's ...... Intercepting the imprint of heaven and earth......" Lu Zheng was a little speechless, this kind of means can also be used by the emperor, but it will definitely not be so easy.

"I see...... Did we lose that battle?" The young man's demeanor was a little lonely, and with a casual wave of his hand, the spatial crystal that imprisoned Lu Zheng had already disappeared: "On your body, I can feel the breath of the Human Emperor and the Demon Emperor, I won't kill you." ”

Lu Zheng suddenly realized that it was not because of this young man's good temper, but because of the Human Emperor Jade Seal and the Demon Emperor's Scepter, he was able to survive.

"Dare to ask seniors, where do you go now?" Lu Zheng hugged his fist.

The young man smiled dumbly and said: "Don't call me senior, I was more than a thousand years old after I was born, and I encountered the battle of the immortals, on the battlefield, I was seriously injured, it was the two big men of the Netherworld Demon Lord and the Abyss Demon Lord who saved me, and I have only survived until now." ”

Lu Zheng secretly said to himself, at the age of more than a thousand years, he has cultivated to the realm of true immortals, how high is this young man's talent?

"If I'm not mistaken, you should be the owner of the human emperor jade seal and the demon emperor's scepter, it's really strange, these two things will fall on you alone, it's a pity, the jade seal and the scepter are still there, the original demon emperor and the human emperor, but they have disappeared, I still vaguely remember that I once saw the scene of the three emperors leading fifteen strong men against the gods from afar. The young man sighed.

Lu Zheng looked at the young man and said: "Although the heavens and the earth are connected now, and the connection between the heavens and the ten thousand worlds and the immortal world has been severed, judging from some of the news I have gotten, I am afraid that it will not be long before the immortal world will start again, and at that time, how can the heavens and all the worlds resist?"

"My mission to stay is to fight against this catastrophe, you don't have to worry about anything, when you achieve the Void Immortal, you can come to the Flood Desolate Remnant Realm to find me, and when the time comes, I will pass on your true immortal skills to fight against the Protoss...... I just hope that those adults have not fallen......" The young man patted Lu Zheng's shoulder, and then a strand of hair broke and burned, turning into an ancient rune, which was imprinted on Lu Zheng's body: "This is my brand, I can use this to come to the desolate remnant realm in the future, and at the same time, this brand can be shot three times to kill all the existences below the Eight Tribulations Void Immortal." ”

Lu Zheng hurriedly said, "Thank you seniors." ”

The young man waved his hand and said, "You're welcome, I don't think I'm as old as you, just call me Qingsang." ”

Lu Zheng nodded, and he was not polite, according to this Qingsang, he has only been practicing for more than a thousand years, even if some years have passed in the battle of the immortals, his age will not exceed ten thousand years old, he is really young.

"Okay, I'm leaving, go find some old friends, open the Flood Remnant Realm, the future ...... Resist the Protoss, you are still needed. Qingsang said to Lu Zheng, turned around and took a step, and completely disappeared at the end of the sky.

Today's events are really a bit unbelievable, like a dream, which makes it difficult for Lu Zheng to accept, the person sealed in the Immortal Crystal Mountain is actually a young Tianjiao, and his task is to open the desolate remnant realm.

"Qingsang's brand......" Lu Zheng groaned, he didn't feel any malice on Qingsang, that is to say, this brand should be the same as what Qingsang said: "Three chances to make a move......

What kind of character is Qingsang? It is not an exaggeration to say that he is now the strongest person in the heavens and all worlds.

His hair can tear the stars when it is scattered at will, and isn't it even more terrifying after being sacrificed by him?

Lu Zheng shook his head, looking at the mess in front of him, he had a sense of urgency in his heart, in the ancient war, Tianjiao like Qingsang was beheaded, what is his current achievement?

"Only if you are strong enough can you resist the invasion of the Protoss, but is there any hope for the heavens and all worlds?" Lu Zheng pondered: "Perhaps, there is still hope." ”

"Whether it is that ghost predecessor or Qingsang, they are all ancient giants, and if they can survive, they must have something extraordinary. Lu Zheng thought about it and remembered the ghost predecessors at the beginning.

Whoa...... The water of the Huangquan River is still flowing gently, eternal, without the slightest change, Lu Zheng calmly stepped into the lake, and the whole person fell silent: "It's a pity that when Qingsang woke up, the golden-winged Qianyuan was directly shocked to death, otherwise there could be one more thug of the Four Tribulations Void Immortal." ”

......

But it was said that far away on the hundredth floor of the Tower of Babel, before the ancient temple, the figure of a young man suddenly appeared, he moved, as if it was a big world distance, just in an instant, he had already come to the entrance of the temple, and bowed to the sculpture in it: "Hong Desolation Qingsang, come here today, open the Flood Desolation Remnant Realm!"
