"How do you open this box?" Yue Yan was entrenched on a white and flawless white jade bed.

Some embarrassed looked at the box in front of them and couldn't help but scratch their heads.

Even a strong man in the fighting god can't break the forbidden box, and it's even more impossible for him to be a small war emperor.

"Great Creation and Great Destruction!" At the same time as Yue Yan's spiritual power exploded, he released the aura of great creation and great destruction, trying to communicate with the fragments in the box.

Then his spirit entered a world with three huge dark stars hanging high in the sky, emitting extremely wonderful fluctuations.

Yue Yan immediately became excited when he saw those three dark stars, which was the same as the first piece he had obtained the Great Creation and Great Destruction Method.

He couldn't wait to fly up and get close to the three dark stars, recover them, and succeed in his cultivation.

However, when he had just approached the three dark stars and was about to communicate with them to subdue them, the dark stars transformed by the three secret methods emitted huge spiritual fluctuations, directly blasting Yue Yan to the ground.

"Damn, it seems that it's not as easy as I thought, Chaos Ancient Divine Codex, suppress me!" Yue Yan smiled slightly, the scene in front of him was completely expected by him.

Then he closed his eyes and directly summoned the Chaos Ancient Divine Book in his soul.

The Chaos Ancient Divine Book shook slightly, and a mysterious wave fell on the dark star.

The dark star was still a little trembling at first, wanting to resist the Chaos Ancient Divine Codex, but the Chaos Ancient Divine Code was too domineering.

Although Yue Yan couldn't drive the true power of the Chaos Ancient Divine Code at all, even a little bit was not something that a few spiritual secret method fragments could resist.

It didn't take long for the three dark stars to fall silent and honestly merge into Yue Yan's body.

Yue Yan only felt a shock to his spirit, a little refreshed, his spiritual power also had a feeling of growth again, with the nourishment of the wooden house pendant, he could feel that now a small Zhou Tian is a big Zhou Tian on top.

He was pleased with the rapid progress of the project, but he suddenly thought of something, and with a wave of his hand, he pulled out a white spar.

This thing is like a stone not a stone, ever-changing, as if it contains all things in heaven and earth, exuding a soft milky white light, with a strong five elements and the power of space, and a world of its own.

This thing is the World Crystal that Yue Yan obtained a long time ago, and even the Fighting God will be moved by it, which is extremely rare.

"Can I try to get a little bit of it down and incorporate it into my own Hybrid Creation Axe." Yue Yan looked at the large piece of World Crystal in front of him and couldn't help but lick his lips, and said fieryly.

"Although the crystal of this world has been divided into several pieces by you, the energy in it is still extremely powerful, and with your current cultivation of the second-rank battle emperor, it is impossible to refine it at all." The Burning Sky Flame Dragon said directly.

"That's ......," Yue Yan had a look of disappointment in his eyes.

"Well...... "Burning Sky Flame Dragon deliberately bought Guanzi.

"But what, tell me quickly." Yue Yan's eyes lit up, knowing that there must be a play, and asked eagerly.

"However, if you can separate a small wisp of it, and then use the power of the Divine Beast Seal to forcibly refine it into your Hybrid Origin Creation Axe, there is a high chance of success, but it mainly depends on your ability to control it." Seeing Yue Yan's eager appearance, the Burning Sky Yanlong said slowly.

"I'll try." Yue Yan was still an impatient after all, just do what he said, he raised his hand and cut off a piece of world crystal the size of a fingernail with the Chaos Ancient Divine Power.

The seven different divine beast seals in his body that had not been impacted suddenly broke open, and the power and strength of the huge and powerful bloodline were only for a moment, causing a trace of cracks to appear in the meridians of Yue Yan's body.

The power of these seven seals is too turbulent and powerful, and with his current physical body, it is a little reluctant to bear just one, let alone seven together.

Yue Yan didn't dare to slack off in the slightest, and immediately began to use the power of this powerful divine beast to refine that thumb-sized piece of world crystal.

He directly turned the ancient divine power of Chaos into Chaos Fire, which was extremely domineering, even the Void and Zero Degrees were enough to ignite, even a holy object like the World Crystal was gradually melting little by little.

It didn't take long for a puddle of white-gold liquid to float in the air, and there was a faintly small world in it, ever-changing.

With a thought, he took out the Hybrid Creation Axe, and with a flick of his finger into the void, the white-gold liquid transformed by the World Crystal was integrated into the Hybrid Creation Axe.

The Mixed Yuan Creation Axe trembled slightly, after all, it was a holy object that the Holy Spirit would be moved by, even if it was just a little, it would be difficult for an emperor-level late-stage soldier to bear, let alone an emperor-level early-stage soldier.

Fortunately, the material of the Mixed Yuan Creation Axe itself is good, and it has absorbed the Qi of Chaos, and a drop of Yue Yan's essence blood has undergone earth-shaking changes, and it has infinite growth, otherwise it would really be unbearable.

"Buzz!"

Gradually, as the white-gold liquid fused, the Mixed Yuan Creation Axe trembled more and more, and a strong buzzing sound sounded.

"Xiaohong, help me create an isolation formation." Yue Yan hurriedly said, he didn't want to cause too much movement in the Jade Void Flower Divine Gate, otherwise there would be a lot of trouble at that time.

"Good!" The Burning Sky Flame Dragon agreed, and his body materialized, still looking like a red-haired little red dog.

His dog's paws kept turning, mobilizing Yue Yan's spiritual power, and laying an extremely mysterious isolation formation around his room, even those who were strong in fighting gods didn't want to notice anything.

"Alright." It's just a few dozen breaths, and the Burning Sky Flame Dragon is arranged.

Watching Yue Yan use the power of the divine beast and the fire of chaos to continuously refine and fuse, the Chaos Yuan Creation Axe nodded again and again.

It didn't take long for the last trace of the World Crystal to merge into the Hybrid Creation Axe.

A huge pillar of platinum light rose into the sky, but was stopped by the formation arranged by the Burning Sky Flame Dragon.

The Hybrid Origin Creation Axe has also changed a little, the original Xuanhuang color of the big axe has a lot of platinum color intersection, the ruler body is still the same length as before, and the axe is a chaos dragon hovering on it, the axe blade is not, but it is also sharper and heavier than before.

Just a light stroke is enough to tear the heavens and the earth, because inside this axe is a world.

"Good baby, Jinjin, you can help me see what grade this axe is equivalent to." Yue Yan couldn't wait to ask Optimus King Kong.

After all, Optimus King Kong is a master of alchemy, and he only has a super alchemy technique like the Ancient Alchemy, and he has no relative ability.

"Judging by its power just now, it should be enough to match the immortal soldiers, but it seems to be an emperor-level late-stage soldier itself." King Kong answered with certainty.

"That's pretty good, hey, there is still some power of the divine beast, and the crystal of the world, the fire of chaos seems to have been refined and fed back into my body." Yue Yan hurriedly closed his eyes and activated the Chaos Ancient Divine Technique.

The momentum on his body soon broke through the second rank and stopped at the peak of the fourth rank Battle Emperor, of course, more power was used by him to bless the flesh.

Yue Yan moved his body, and that powerful body crushed the void around him in one fell swoop, so frightened that he hurriedly gathered his strength.

"Now I am only physically strong, I am afraid that it is enough to match the second-grade battle immortal or even the third-grade battle immortal, and my Chaos Realm realm can enable me to fight against the fourth-grade battle immortal, and my spiritual power is also enough to rival the first-grade battle immortal, as well as the Mixed Yuan Creation Axe, these together should be enough to match the fifth-grade battle immortal, and the sixth-grade battle immortal I can also retreat with my whole body." Yue Yan thought about it, very satisfied.

His overall strength has improved and has not fallen.

"I don't know how many days have passed, let's go out first." Yue Yan pushed open the door and walked out, the sun outside was already hanging high, and he squinted his eyes.

"I'm already out of the customs, Xiaorui, Tianxiang, let's go back to the Dou Shen Academy." Yue Yan's spiritual power was transmitted to Zhang Tianxiang and Xiao Rui.

It didn't take long for the two to appear in front of him.

"You've been cultivating for a long time this time." Zhang Tianxiang said.

"How many days have passed now?" Yue Yan asked.

"It's been half a month, and your cultivation seems to have improved a lot, can this spiritual secret method still help your cultivation break through?" Zhang Tianxiang asked suspiciously.

"That's not it, it's just that I refined a small piece of the World Crystal and integrated it into my soldiers, and then a wisp integrated into my body, so I broke through the two grades." Yue Yan explained, and as he spoke, he released the aura of his four-rank Battle Emperor peak.

"Boss, it's not fair, you hang up, I used to be higher than you, but now you are so tall than me." Xiao Rui was very dissatisfied.

"It's just how to open the hanging, you can also open it if you have the ability." Yue Yan raised his eyebrows and said with a smile.

“……”

"Okay, okay, don't make trouble, since there's nothing to do, let's go back to the Dou Shen Academy." Zhang Tianxiang shook his head and interjected.

"Well, the appointment with Leng Feng can be advanced, I don't want to give this poisonous snake another chance to poison the people around me." There was a killing intent on Yue Yan's body.

Then, after Yue Yan and Piaoyun said goodbye, they were on their way back to the Dou God Academy.

"Be careful!" Yue Yan's pupils shrank, and the explosion of divine power directly shook Xiao Rui and Zhang Tianxiang apart, and he did not hesitate to cast the Chaos Realm.

A hand silently appeared in front of Yue Yan and smashed into his face with a punch.

Although Yue Yan reacted, his body couldn't keep up with it He could only cover his face with dragon scales, and then he felt an extremely powerful force fall on his face, and then he turned into a streamer and smashed into the ground fiercely.

A huge pit thousands of feet wide and I don't know how deep it is.

In his original position, a fierce and bloodthirsty young man appeared, looking at the huge pit below with a smile on his face, and there was a huge world behind him, which had a demonic aura.

"Damn, how can this guy's aura be so powerful." Zhang Tianxiang's face changed drastically, the person in front of him was too powerful, and the breath on his body alone gave Zhang Tianxiang a great sense of oppression, if it weren't for his divine body, I am afraid he would have been a little unbearable.

"High-level Demon Immortal!"
