"Congratulations on passing the Yanrong Saint King assessment! You are qualified to learn the secret technique that the old man obtained by chance, and the old man has no way of knowing what the name is, the old man calls himself the Battle Word Technique!"

The old man's voice sounded at the right time.

"Did you pass?"

Cao Yu opened his eyes tiredly, and he had a feeling of the rest of his life, so that he didn't hear the key words of the Yanrong Saint King assessment and the battle word trick clearly.

"Yes, you have passed the assessment, but there is still one last hurdle to overcome if you want to obtain the Inheritance Secret Technique!"

Cao Yu, who was overjoyed, heard that there was still a hurdle, and 10,000 grass and mud horses galloped through in his heart in an instant!

Enduring the weakness and the unhappiness in his heart, he calmly asked, "Senior, I don't know what else I need to go through to get the so-called secret technique?"

If it weren't for the fact that he had no choice, he wanted to give up directly now, but now there is no turning back from this situation, so he can only bite the bullet and meet the requirements of the immoral old man.

"My true body is below this magma in the center of the earth, and the secret art is above my true body!"

The voice of the Yanrong Saint King was extremely flat.

Hearing this, Cao Yu directly rolled his eyes and fainted.

This Nima is too pitiful!

This is Cao Yu's last thought before he faints, let him pass through this magma, wouldn't it send him to death!

In fact, the secret technique of the Yanrong Saint King was originally intended to find a stronger heir, and with his strength in that continent, the qualifications of the heir were at least a saint.

Because he was frantically hunted down, he didn't understand the overall strength of this continent, so the lineage that was arranged was also aimed at the saints.

The previous formation was still flexible, and it was weighed by the strength of the interlocutor himself, but this piece of magma underground became a deadly obstacle for Cao Yu.

With the strength of a saint, this magma is nothing more than a bath like a hot spring.

But with Cao Yu's current strength, even if he has all kinds of ability, he can only cry in the sky.

Unless...

The Chaos Source Bead can be contacted, but there are still some permits.

Seeing that Cao Yu was attacked by the direct qi and blood, coupled with severe prostration, and fainted directly, the Yanrong Holy Lord felt quite helpless.

When he saw Cao Yu enter this underground world, he knew that the strength of the cultivators in this continent was so weak.

thought that his inheritance would be buried in this underground space forever, but Cao Yu's performance surprised him and saw the dawn of hope.

Especially the sharp broadsword that appeared at the end, he felt that with his strength, he couldn't control it even in his heyday.

If he was still in perfect form, or if his soul was even stronger, he would want to take this body and snatch the sword in his hands.

He believed that if he regained his strength, he would add that terrifying broadsword.

In that continent, apart from those few great powers, who would dare to oppose him.

However, the strength of this underground space and inheritance left behind back then is no longer one in ten, and the only remnant soul is only the one who maintains this space formation, and once it leaves this space, it will be scattered.

Since he couldn't get any treasures, the Yanrong Saint King was relieved and quietly waited for Cao Yu to recover and wake up.

Cao Yu, who had already fainted, was shrouded in scorching heat, although this underground space was not large, but the secret realm arranged by the means of the Holy King was naturally considered in all aspects.

In order to maintain the operation of the entire secret realm and continue to not decay, the Yanrong Saint King arranged a super large spirit gathering array back then, and it was precisely for this reason that the aura of the Heavenly Wind Academy was stronger than other places.

Cao Yu only cared about the battle before, where did he care about the aura in this space, and it was naturally the fastest to directly restore the aura with spirit stones.

Now in a fainting state, his body absorbed the aura in the space on its own, directly forming a small aura vortex around his body.

Thanks to the benefits of body remodeling, the absorption of Reiki is also extremely fast.

When Cao Yu woke up again, all the true qi in his body had been recovered.

The chest that was slapped by the fire demon was restored by the warm current of the killing heart, and the wounds on his body were all restored at this moment.

"I am... Asleep?"

"Huh, how did my true qi recover on its own? How long did I sleep!"

A series of questions popped up in Cao Yu's mind.

Seeing Cao Yu wake up, the slightly joyful voice of the Yanrong Holy King sounded.

"Little friend, you've finally woken up! You've been asleep for three days and three nights!"

"What! I slept for three days and three nights!"

Hearing this, Cao Yu was shocked, it seems that this time he has enough prostration, although the true qi has been fully recovered, but the soul power has only recovered less than half, this is still because of the bodhichitta method working on its own.

"Senior, I don't want the secret technique you said, I just want to leave, can you send me out?"

Cao Yu looked at the hot magma below, and couldn't help but feel a little frightened in his heart.

At the end of the day, he's still a 15-year-old!

"There is no way back when you come here, either pass the test and get my inheritance, or turn into nourishment for this magma pool!"

The words of the Yanrong Saint King were like a basin of cold water poured on Cao Yu's head.

Hearing this, Cao Yu had a-eating expression, his eyes seemed to be filled with tears, and he said pitifully:

"Senior, why are you so ruthless, you didn't leave any way out for the interlocutors at the beginning!"

"This secret art is related to the lives of the common people, if the news leaks, millions of corpses will be ambushed, and the blood will flow like a river!"

Yan Rong said solemnly.

"Is it really as amazing as you say?"

"You can only know this if you try it yourself!"

As soon as this old man said this, Cao Yu suddenly became interested, a powerful existence that can create a space secret realm, naturally he will not bluff, it must be that the secret technique is extremely against the sky.

Now he was eager to see the secret technique, and his mind was racing to think about how to get into the magma.

He had thought of frantically casting the Heaven Devouring Divine Technique when he passed, turning all that magma into his own short-term power.

But just getting close to the magma and performing the Heaven Devouring Divine Skill made his meridians extremely painful.

Obviously, he couldn't handle the scorching heat of the magma.

By the way, I don't know if that old man can help me get in touch with the Chaos Source Bead.

This is Cao Yu's last straw, if he doesn't work again, then he will be trapped here to death!

"Senior, I sense that this space is completely isolated from the outside world, can there be a way to remove the power of isolation and let me contact the powerhouse of our academy!"

Cao Yu didn't know the old man, so he chose to ask if he could contact the outside first.

If Senior Brother or that Supreme Elder could take action, maybe they could rescue him, even better!

"No! you can only manipulate the inside, you can't get in touch with the outside, unless you get the inheritance, you can't get in and can't get in with it, of course, if you have the strength of the Holy Monarch or above, you can forcibly break through my space!"

Hearing this, Cao Yu was speechless again, this is not good, that is not good! Is he really going to die of old age here.

After thinking about it for a while, and not caring about whether the Chaos Source Bead would be leaked, Cao Yu asked again:

"The power of isolation in this space can always be evacuated!"

After Cao Yu finished speaking, he pricked up his ears with anticipation, hoping to hear some good news!

I don't know if God favored Cao Yu, but this time the Yanrong Holy King finally gave him a satisfactory answer.

"It's easy!"

After the voice disappeared, after a while, Cao Yu felt that the sense of depression disappeared, and then the connection with the black hole in the sea of consciousness was felt again.

Cao Yu cried with joy, he felt that it was really not easy, and after entering this space, he ran into walls everywhere.

"Xiao Yuan, can you hear me?"

Somewhat disbelieving, he tried to call out to Xiao Yuan.

"Don't make this handsome guy sleep!"

Although Xiao Yuan was not very polite to him, this voice was like a heavenly sound to him.

Then I tried the Chaos Library feature again!

His eyes were fixed on the magma lake, and his mind moved, and suddenly a message about magma appeared.

"The geocentric magma, a unique magma formed from a third of the earth's center, has a certain chance of condensing the earth's spiritual milk!"

Cao Yu didn't pay much attention to other things, but the four words 'earth soul milk' were stared at by Cao Yu!

Produced by Chaos, it must be a high-quality product!

After being in contact for so long, in his perception, this Chaos Source Bead didn't even bother to mention some low-level or not very rare things.

This is the urine nature of Yuanzhu!

"The magma at the center of the earth is composed of the purest fire element at the center of the earth, and it can also be the source of fire!"

What is called bitterness and sweetness, Cao Yu is almost in tears!

If it weren't for the Chaos Source Pearl, he wouldn't know that a golden mountain was in front of him, and he would just go out without anything.

I can't wait to slap myself at this moment!

Seeing this, Cao Yu directly let him analyze!

Give me an analysis!!There must be a good way!

"Advantages: The geocentric magma is extremely suitable for the tempering of the monk with the fire attribute, and it can get twice the result with half the effort。。 ”

"Disadvantages: Due to the extremely high temperature and purity, only a very small number of monks can absorb the cultivation。。 ”

"Suggestion: According to the current condition of the host, most of this energy can be used to activate the Chaos Source Orb, and at the same time, a trace of it can be used as a quenching body!"

Seeing this, Cao Yu couldn't wait to take out the Chaos Source Pearl and kiss it a few bites, it was really powerful!

"Xiao Yuan, there's work to do!

Cao Yu was not so polite this time, because he was bringing benefits to Xiao Yuan.

"Boy, if you don't have good things, see if I don't peel your skin!"

Xiao Yuan's extremely reluctant voice sounded, and then he appeared in Zhihai, and saw the situation outside through Cao Yu Zhihai.

"What is this? ”

"Hahahaha! That's right, it's the origin of fire, this thing is not bad!"

Cao Yu smirked.

"You kid has good things everywhere you go!"

Just now he got the Great Dao Fragment, which allowed him to open the Chaos Library function, and in a blink of an eye, he encountered a lake-like fire source.

This luck is simply not too against the sky.

"Let's do it, you say how to do it!"

"This thing can refine your Chaos Holy Body, and at the same time, it can activate about 1% of the Chaos Source Orb.

"What! only one percent of it can be activated!!"

In Cao Yu's opinion, so many fire origins can be activated by at least about 10%!

When the time comes, it is estimated that if something good is developed, then his open life will be even more crooked.

"This is not the purest source of fire, there are some impurities in it, and the concentration is not enough, 1% is not bad!"

Xiao Yuan explained.

"Okay, without further ado, let's get started!"

Cao Yu chatted with Xiao Yuan for a long time in the sea of knowledge, but in fact, it took a while to be outside.

"Senior, are you sure you can reach your true place by passing through this lava?

He was really afraid of this old man, and if he had another problem after he passed, he would probably be so angry that he would vomit blood.

"No, breaking through the magma is where the king's true body is, you can rest assured!"

"Good!"

Xiao Yuan controlled the Chaos Source Bead, and Cao Yu himself devoted himself to refining the Chaos Holy Body.

Confirm with Xiao Yuan that he will wrap him and only inject a trace of quenching into his body before jumping down boldly.

Although Xiao Yuan assured several times, seeing the flaming magma, Cao Yu's face turned pale for a while!

"Poof!"

Cao Yu was directly submerged in the magma, and at the moment when he was about to make contact, a transparent film enveloped Cao Yu, and the magma in the center of the earth around him was frantically burning the transparent film.

But it couldn't shake the slightest, and at the same time, a suction force poured out of Cao Yuzhihai.

A small hole was opened in the transparent film, and then the magma in the center of the earth flowed into Cao Yu's meridians.

"Ahh

Cao Yu, who was caught off guard, shouted heartbreakingly!

There was still a thin film enveloping the magma in the center of the earth, but despite this, the incomparably hot fire origin burned Cao Yu's veins extremely red.

"Boy, endure what ordinary people can't endure, so that you can enjoy the blessings that ordinary people can't get!"

Xiao Yuan's seemed to be a tranquilizer, which made Cao Yu grit his teeth and endure it.

Even if his luck is against the sky, he refuses to endure hardships, his strength does not improve, and he is heavily protected, but for him, he is possessed by a disaster.

You will be tortured and killed every minute!

When the magma at the center of the earth began to destroy Cao Yu's body, the Chaos Source Bead also automatically released golden light to protect it, and at the same time restored the meridians on the side.

Most of the Fire Origin was sent to the Chaos Source Bead, and Cao Yu's body was like a transportation pipeline, but as the refining progressed, the route of the Fire Origin would continue to change, so that the purpose of quenching the body could be achieved, which was deliberately done by Xiao Yuan.

Xiao Yuan said that he disliked Cao Yu most of the time, but he was still dedicated to Cao Yu, after all, this was the will of heaven in the dark, and he didn't dare to disobey.

Cao Yu was once again in a state of wakefulness and wanted to die, and the meridians, flesh and blood, and bones were all tempered.

In the end, fortunately, the membrane protected by the village was directly removed, and Cao Yu had adapted to the magma.

Immersed in the source of fire, feeling the endless pain and the most essential source of fire.

Cao Yu's body and mind sank into a state of perception, and his understanding of fire deepened rapidly, which was different from that of the Chaos Library.

This is the most direct personal feeling! The Chaos Library is forcibly instilling other people's feelings into Cao Yu.

After their transformation, after all, they will lose their most essential true feelings!

At the end of the tempering, Cao Yu's eyes were covered by a layer of firelight, if he cultivated the fire attribute technique now, Cao Yu could travel thousands of miles in a day, and the efficiency was extremely high!

Synchronous fire attribute martial arts will also be handy!
