Cao Yu, who was in the magma world, had a bleak face, and as the temperature continued to rise, he was almost unbearable, and hurriedly shouted: "Senior, what do you need to do to pass the assessment?"

"Just defeat the puppet with a hundred times the combat power of your realm~" The old man's voice sounded indifferently.

"100 times more combat power, you are murder!!"

Cao Yu's face darkened when he heard this, the hundredfold combat power of the Martial Emperor Realm was definitely beyond the Martial Zun Realm, and with his current strength, the most extreme could only fight with the Martial Emperor Realm's ninefold peak.

Wu Zun Realm could press him to the ground and rub him almost with a single hand.

"Those secret techniques are very qualified to cultivate, and the old man can gallop on that continent just by learning a little bit of skin, but it's a pity that the rumors leaked and were jointly besieged!"

The old voice did not reply to Cao Yu's words, but said something that didn't matter, as if to attract Cao Yu.

"What kind of secret art? senior!"

When Cao Yu heard that he could gallop across the continent after learning a little fur, his eyes suddenly lit up, and he didn't care about the incomparably hot body around him.

"Wait until you pass my assessment!

The indifferent voice echoed in Cao Yu's ears, and there was no response to his further questions.

When he wanted to contact Xiao Yuan through Zhihai to ask for a solution, he found that there was no response at all.

"This old madman is so ruthless, he has directly cut off all external contact!"

Cao Yu looked around with tears in his eyes, and after the temperature rose to a certain level, it seemed that it no longer rose.

Standing on the central stone platform, he looked at the magma around him and began to tumble violently.

Then the head of a monster covered in flames emerged, its eyes cold and merciless, staring at Cao Yu as if it were a dead man.

"What kind of monster is this?"

The magma monster's body slowly floated out, and finally suspended on the surface of the magma, and when he saw Cao Yu, it was like looking at an ant.

Then he bent down and scooped a piece of magma into his mouth, and let out a laugh after drinking.

"Finally a fresh piece of flesh and blood!"

"This is the Flame Demon!"

Cao Yu had absorbed so much knowledge in the Library Pavilion, and he had some understanding of the strange creatures in the Xuantian Continent.

After saying that, the Flame Demon pounced on Cao Yu viciously, as if he were a fresh delicacy.

"Tiny human, make me dinner!haha!"

The fire demon's eyes were full of excited blue fire, and his huge body was 3 meters high, and his fists were bigger than Cao Yu's head.

Before the fist arrived, a strong scorching wind blew Cao Yu's body backwards.

Feeling that strong aura, Cao Yu didn't dare to directly confront him, the key is that now he is not only far from lacking in true qi, but also has some injuries in his body.

So the best thing to do now is to retreat first, and then recover some of your true qi.

"Step on the third floor!"

The body regressed extremely quickly, and twenty times the speed of sound exploded instantly, and at the same time, he ran the Nine Heavens Killing Technique and the Flood Desolation Refining Body Technique at an extremely fast speed, frantically absorbing the spirit stones held in his hands.

Now the only thing that can save his life is the more than 1,000 low-grade spirit stones rewarded by the previous academy, fortunately, he didn't use them all up on the spur of the moment at that time, otherwise it would really be the end of the road now.

Seeing that the punch was unsuccessful, the fire demon raised his head angrily and roared, and then the color of the flames on his body changed from red to orange, and his aura suddenly skyrocketed again.

"Weng!"

The speed is close to 20 times the speed of sound, but it is still slightly inferior, and he can only follow behind Cao Yu's ass with his eyes.

"You stupid devil, give me death!"

Cao Yu held the Meteor Knife, relying on his speed advantage, he appeared on top of the Flame Demon's head, injecting all his true qi, including some of the attack effects attached to the Heaven Devouring Divine Skill.

"Bell!"

The sound of the clash of iron and stone sounded, and Cao Yu's meteorite knife was cut out of a gap, and the flame demon was forced to fall down, falling into the magma.

But in less than a breath, he roared out again, but his body was not damaged at all.

Seeing this, Cao Yu's pupils shrank, and a sense of powerlessness welled up in his heart.

How can this Nima fight! With all his strength, even the skin of this flame demon can't be broken!

There are many tribulations that have been experienced since the crossing, and he believes that there is no infinite road to the sky, since he can pass the ninth level and be allowed to enter, then the existence of this arrangement formation should not be teleported indiscriminately.

After all, the people who went in to break through were all disciples of their own academy, and Tianfeng Academy would not kill geniuses.

However, this time he really miscalculated, this formation was not arranged by the powerhouse of Tianfeng Academy after all.

Rather, it was the remnant soul that was established, when the Tianfeng Academy was established in Yunyue City, it was the formation that could continue to temper the strength of the academy's disciples.

Those patriarchs didn't know that there was a follow-up after the ninth level, because there had never been a disciple who could successfully break through the nine levels in a row before.

Cao Yu gritted his teeth and persisted, hoping that the elders outside could find out the clues.

But his thoughts were destined to be shattered, because the elders and academy disciples outside could only see the nine pillars of light that had lost their luster, and they had no idea where to start.

After the fire demon rushed up, he still rushed towards Cao Yu frantically, but his speed was a little slower, and he could only be hit back into the magma by Cao Yu several times.

"Roar!!!

The fire demon raised his head to the sky and roared wildly, the orange flame on his body changed again, first turning yellow, and then the fire demon seemed to feel that it was not enough, and roared angrily, and the aura on his body rose sharply.

The color of the firelight around his body turned green, and the aura at this time was more than ten times stronger than at the beginning, and his strength was comparable to that of the early stage of Wuzun.

The fire demon sucked into the lava lake, and a large piece of magma was sent into his mouth.

This is a magma-eating monster, Cao Yu's eyes are shining, and he seems to have seen something good!

I made up my mind that in the next battle, I couldn't let this fire demon come into contact with magma again, and over time, the fire demon would be like a rootless ping, and it would be self-defeating.

Cao Yu, who was going to fight hard, frantically cast the Heaven Devouring Divine Technique, and because the fire element was extremely vigorous in this space, most of the people who devoured it were fire elements.

But if you use a fire attribute attack to fight this flame demon, it is tantamount to a meat bun beating a dog!

Give back the fire demons!

Therefore, Cao Yu could only wrap multiple layers with thin water attributes, trying to reduce the damage caused by the flames on the surface of the flame demon's body.

Knowing that the flame demon is physically strong and unreasonable, Cao Yu can only take tricks.

But the speed of the transformed Flame Demon was already a little faster than Cao Yu, so he couldn't take advantage of it.

"Boom, little ghost, come in and make me dinner! human flesh hasn't tried it for a long, long time!"

The flame demon whose strength had skyrocketed looked at Cao Yu playfully.

"Disgusting ugly monster, let me die!

Cao Yu was used as a food teaser, and the golden true qi in his body surged towards the Meteor Knife, and with the power of the gold element, he frantically slashed towards the fire demon.

However, it backfired, Cao Yu's big knife was grabbed by the big hand of the fire demon, and the terrifying huge force made Cao Yu unable to move the big knife at all.

"You're too weak!"

The fire demon smiled disdainfully, and then slapped Cao Yu's chest like a fly.

"Poof!"

The moment it was photographed, a large mouthful of pale golden blood gushed out!

Seeing the pale golden blood, the flame demon was immediately excited.

"Haha! It's really a good luck to be a beautiful body! I've been imprisoned by that old ghost for tens of thousands of years, and I can't come across such a delicacy!"

Between the words, the Firedemon revealed some stories about it.

It turned out to be imprisoned here, and as for the old ghost, it must be the owner of the old voice.

After Cao Yu was shot out with a blow, his body was like a kite with a broken string and fell heavily on the central stone platform, it seemed that the fire demon deliberately did not let Cao Yu fall.

Because he was afraid that Cao Yu would fall and turn into a skeleton directly, or maybe there would not be even bones left, which would go against his crazy appetite, and obviously he didn't want to do that.

"Bang!"

The flame demon stepped heavily on the stone platform, making a loud noise, salivating at Cao Yu lying on the ground.

Because the temperature was too high, the clothes around him had long since turned into powder, and in the eyes of demon beasts like Yan Demon who didn't have much intelligence, it was a beautiful food.

Cao Yu, who was lying on the ground, had a sluggish look in his eyes, and his heart burst out with strong unwillingness, and he finally had such bad luck.

Receiving the gift of the killing god Bai Xuan, although it was conditional, he had no other choice in that case, and then the inheritance of Tianxuanzi, which allowed him to shine above the Danta Dabi.

And the Chaos Source Bead brought him the most surprises, and it also saved his life.

At this moment, he was still desperately shouting for Xiao Yuan in his heart, but to no avail.

It seems that at the beginning of the layout, this space completely deprives the people who enter the connection with the outside, perhaps thinking about the death and resurrection, or maybe not wanting the loser to go out and spread the inheritance.

No wonder no one has discovered it for tens of thousands of years, one is that the difficulty is too high, and the mortality rate is too terrifying, this is simply ten deaths!

Maybe it was the strong unwillingness in Cao Yu's heart, and at the same time, even though the body reshaped by the Chaos Source Bead had been broken, and the bones and internal organs had been destroyed.

The blood and true qi of the body were directly blocked, and then flowed back into the dantian.

After the golden true qi and pale golden blood returned to the dantian, they were strangely absorbed by the killing heart in the dantian.

After the heart of killing is absorbed, it is like a heart, poof!

A powerful wave spread from Cao Yu's body, and the flame demon was a little surprised when he saw this, this ant-like body could release such a powerful aura?

But if the duck in his mouth is not eaten, how can the fire demon be willing, afraid that the night will be long and dreamy, so he bent down and grabbed Cao Yu's body.

When he opened his bloody mouth and was about to bite Cao Yu's skull, just when Cao Yu's head was only less than a fist away from the flame demon, a finger emitting a light red light gently pressed against the bloody mouth.

The fire demon roared angrily at the finger's command, and a violent stream of heat poured out of its mouth, unable to move forward even a single inch with all the strength it could eat.

"Ugly monster, Lao Tzu is not something you can eat!"

Cao Yu's indifferent voice came out, and then a fist that seemed to be weak but exuded red glow hit the fire demon's front teeth.

"Click!"

The flame demon's teeth broke in response, and the painful flame demon threw Cao Yu to the ground, covering his teeth very spiritually, and looking at Cao Yu angrily.

"You damn ant! My Green Flame Demon Mutation can't kill you!"

He roared again, then slammed his fist into the ground, and the green flames on the fire demon's body changed again, and the color quietly changed to blue.

At this time, the aura of the flame demon was already approaching the fivefold realm of Wuzun.

"This Nima! Even if it is a hundred times the strength of the Martial Sect Realm, it is not so strong!"

"Old man, you're cheating! This is already a hundred times more powerful!"

Cao Yu shouted into the air, trying to call out the immoral old man.

"This was originally laid out by my body, not considering that the fire demon can absorb magma and become stronger and stronger, but at present, there is nothing I can do!

The old voice explained helplessly.

Cao Yu's face was as ugly as eating when he heard this, could it be that the previous good luck was used up, and now the bad luck is used here!

Cao Yu, who had nothing to love, scolded the eighteenth generation of the old man's ancestors.

But now that his body has inspired the heart of killing, that kind of warm current has reappeared, but his strength has not improved much, and he can only fight with the fire demon in this state.

He didn't know if the Fire Demon would become again, and when that time came, he would really be cornered.

At this point, Cao Yu didn't care if the secret would be leaked, and with a flick of his hand, a powerful weapon appeared.

It was the 'God Butcher Knife!' that he got from Bai Xuan at the beginning.

After the God Butcher Knife appeared, a strong sense of breaking free came from Cao Yu's hand, and at first it was estimated that he was too weak and was completely ignored by the God Butcher Knife.

Now that the heart of killing has been activated, his strength is comparable to the fifth level of the Wuzun Realm, but for the God Slaughter Sword of the God Realm, Cao Yu at this time is still too weak to be used by the owner of such garbage!.

"You ugly monster can see the God Butcher Knife, count your fate!"

Cao Yu combined the knowledge he absorbed from the Library Pavilion to eliminate many of the drawbacks of the World-Destroying Sword Technique, and at the same time comprehended a trace of sword intent, this Sword Technique can be said to be an improved version of the World-Destroying Sword Technique!

Holding the God Butcher Knife that seemed to weigh hundreds of millions of pounds in both hands, he slashed at the fire demon with difficulty.

"The first form of the world-destroying sword technique!

Then a nearly transparent sword flew out, and the fire demon felt an extremely terrifying aura, and struggled to drill into the magma.

But how could Cao Yu let it get his wish, frantically activated the God Butcher Knife, and directly locked the fire demon with a powerful sword intent, but the fire demon struggled frantically to no avail.

That wisp of transparent knife skipped the fire demon silently, and in just the moment of contact, the fire demon's breath was directly extinguished!, and the huge body was disconnected from the waist in unison, and the cut surface was extremely smooth.

At first glance, it is clear that it is cut by an extremely sharp weapon.

"Bang dang!

Two Flame Demon bodies fell into the magma, and the entire magma space was once again tranquil!

"Whew!

Cao Yu used the last trace of true qi to take back the God Butcher Knife back to the exclusive ring, and then sat down on the ground weakly.

Using this God Butcher Knife was too consuming true qi and soul power, and the warm current that originally gushed out of the killing heart was absorbed by the God Butcher Knife in an instant.

At the same time, the true qi and soul power in his body were almost completely exhausted, and he didn't even have the strength to stand up now.

I really don't know why it won't be so difficult to use the God Butcher Knife in Los Angeles, and after thinking about it, only Bai Xuan secretly helped.

"Hey, this thing really can't be used unless it is absolutely necessary, otherwise it will be slaughtered by others every time it runs out!"

Cao Yu, who had survived the catastrophe, let out a sigh of relief and fell straight to the ground, he was too tired.
