Even if they relied on robbing the resources of the low-level martial arts country, they could not make up for the huge consumption of materials and aura, and there was only one way to solve this problem, and that was to climb to the eleventh-level martial arts country.

Upgrading from level 10 to level 11 is no longer as simple as improving the cultivation of each person, and there is also only one method prescribed by the high-level Martial Arts National Alliance, that is, it involves the galaxy battlefield.

The so-called galactic battlefield is a huge void space, a space full of debris, boundless, mysterious, full of all kinds of beasts that can easily destroy the martial arts, as well as powerful hurricanes.

Once blown by a hurricane, even a martial artist who has cultivated as a martial artist will be instantly dissolved into ashes.

In addition to the hurricane, there are also a large number of strange maelstroms, these maelstroms will emit extremely strong spiritual power fluctuations, even if they are martial artists of the Martial Sect, as long as they are swept in, they will inevitably die.

And only the eleventh-level martial arts nation can come and go freely in the galaxy battlefield.

Every two hundred years, there will be a galaxy war, and the two warring sides are all warrior states above level eight, and this kind of tragic war is allowed and promoted by the entire warrior alliance.

Anyone who can win more than a hundred times in a row will be upgraded to the level of the warrior country to level eleven, and will get a lot of materials and aura, of course. In addition, the tenth-level country can also elect a representative, let the alliance directly pass on the merit to him, and help him improve his cultivation beyond the human tribulation stage, naturally these are small rewards, what really makes all the participating tenth-level martial arts countries crazy is that the winner will be rewarded by the martial arts alliance with a planet to be used as a base for the victory.

As a martial artist, he naturally attaches great importance to the aura of heaven and earth, as well as the magic weapon of materials, and the most basic thing as a martial artist is aura and materials, and the planet contains countless aura and magic weapons, of course, it will make all martial artists crazy.

But only the eleventh-level martial arts country will have a planet, and naturally this has become a symbol of strength, but to become an eleventh-level martial arts country, the assessment is extremely strict, and it is necessary to win a hundred times on the galactic battlefield once in two hundred years in order to get a rewarded planet, and within the prescribed thousand years, this planet must have ten complete first-level to tenth-level martial arts countries in order to form a virtuous circle.

The duel on the battlefield outside the galaxy is the only way for the ninth-level martial arts country to upgrade, and the same thing will be staged on almost every planet, generally speaking, the martial arts countries above the eighth level will not interfere in the battle of the martial arts countries below the eighth level, unless there is a special exception, if the ninth-level martial arts country is angry, the following martial arts countries can be easily destroyed, and according to the speculation of most of the top martial artists, the eleventh level is not the top martial arts country, and there is a certain chance and chance that it can be upgraded to a twelfth-level country, but the current way is still unknown。

The cruelty and bloodiness of the galaxy battlefield will lead to the remnants of many corpses and discarded materials, which requires someone to clean up regularly, and the tenth-level martial arts country has extremely strict regulations for the clean-up work, which can only be dealt with by the seventh-level martial arts country and below, and the magic weapons and materials left in the galaxy battlefield are undoubtedly god-like existences for these low-level countries.

The galactic battlefield is divided into countless duel areas, and each region has its own special low-level martial arts nation to clean up.

Therefore, in order to obtain the qualification to enter the galaxy battlefield to clean, countless sects, whether it is the righteous path or the demonic path, are fighting to the death.

It was under this background that the Heavenly Wolf Valley was created, mainly to select the people of the sect who were qualified to go to the galaxy battlefield to clean up.

And there is a huge formation outside this Heavenly Wolf Valley, which was placed by a powerful martial artist from the ninth-level martial arts country six thousand years ago, unless there is a specific law seal closed, no one can enter, unless it has reached the level of human robbery and cultivation, it can come and go freely.

This is also the reason why although the old man of the six demons wanted to find Chen Fan to duel, he couldn't rush into the Heavenly Wolf Valley, because with his cultivation, he still couldn't break through the sealing formation.

Sirius Valley is not only a battleground for the clean-up of the galaxy battlefield, but also the only entrance to the galaxy battlefield in the Fengqi Empire, so it has become a place where countless sects have fought for blood.

The clean-up work of the tenth-level martial arts country for the galaxy battlefield, in addition to restricting the martial arts countries below the seventh level, there is also a point that the martial artists who enter cannot exceed the martial king stage cultivation.

Generally speaking, if the qualifications are confirmed, the surviving martial artists of the Martial Emperor Period who remain in the Heavenly Wolf Valley will be teleported to the galactic battlefield, and there is no need to leave the valley at all, and they will not be uniformly teleported back until the expiration of the hundred-year period.

And the old man of the six demons naturally knew this, so he asked Chen Fan to fight a decisive battle outside the Heavenly Wolf Valley, otherwise, if he wanted to duel with Chen Fan again, he could only wait until a hundred years later.

And a hundred years later, there are many variables, who knows if his six demon old man is still alive?

And at this moment, almost every martial artist in the Heavenly Wolf Valley knows that there is a murderous madman, whose cultivation is unfathomable, and some people analyze that he has reached the stage of the Martial Sect, but he doesn't know how to enter the Heavenly Wolf Valley.

Chen Fan has been walking south in the Heavenly Wolf Valley these days, and his spiritual power is tumbling very violently in his body, and at the same time, the killing intent in his heart has also become more dense with the endless killing.

His mind was at a loss, he didn't know how many people he had killed, and he didn't know that the surviving people in the Heavenly Wolf Valley had reached the point where they were terrified of him and talked about him.

Ten days later, Chen Fan, who had been confused, came to the southernmost edge of the Heavenly Wolf Valley, where was a steep mountain cliff, as long as he leaped forward from here, he would leave the Heavenly Wolf Valley, but if he accidentally touched the sealing formation, he would naturally automatically teleport to the Heavenly Wolf Valley.

Because this Heavenly Wolf Valley is only allowed to enter, not to exit.

Chen Fan rose up, broke through the formation in an instant, and came to the top of a mountain, he looked into the distance, and couldn't help but shed two lines of blood and tears, at this time, his chest was as painful as being pierced by thousands of swords.

"Why, why!" Chen Fan looked into the endless distance and couldn't help but roar loudly.

"Chen Fan, don't be excited, I also understand your current mood, but I still advise you, don't go to the Six Demon Old Man to duel first, he has a magic weapon of the Martial Sect stage, if you go to him, you will definitely die. The old man doesn't have much essence on his body now, and he can't help you defeat the old man of the six demons at all. Yang Zheng said slowly.

Chen Fan's face was expressionless, but he nodded heavily.

"The old man suggests that you go to the galaxy battlefield, if you can pick up the Divine Reverse Bead when you get there, you will definitely be able to improve the old man's cultivation, and when the old man recovers his physical body, his ten six demon old men are not my opponents!" Yang Zheng said solemnly.

"God reverses the beads......" Chen Fan muttered to himself, frowning.

In the Heavenly Wolf Valley, the Righteous Dao and the Demon Dao Sect had fought many times in this month's time, but whenever the martial artists on both sides saw Chen Fan passing by, they immediately stopped, got out of the way, let Chen Fan pass by slowly, and waited for him to pass by, and then continued to fight.

Chen Fan thought about Yang Zheng's words and felt that it was very reasonable, so he sighed heavily and turned back to the Heavenly Wolf Valley. He found a secret cave in a cold place in the Heavenly Wolf Valley, and as soon as his mind moved, he immediately went into retreat and practiced, thinking about the drastic changes in his body over the past few days.

The first is the problem of the aura in his body, he has absorbed a thousand strange aura before, although there are also a large number of cold qi in it, but it has never been like these days, he can burst out with strong strength, and he can even kill a martial artist of the same level in one move.

This is extremely incredible, not only Chen Fan is puzzled, but even Yang Zheng feels inexplicable.

And the sudden increase in spiritual power made Chen Fan feel more confident in his heart, but when facing this spiritual power, he had a strange feeling.

In other words, Chen Fan felt that his spiritual power seemed to contain a certain substance, and this substance was the reason for the sudden change in spiritual power.

The reason why it was not discovered before was because this substance was very small in spiritual power, but now, it has suddenly increased.

What kind of substance it is, Chen Fan can't say now.

"Boy, try to use that Holy Light Technique to find out the source of the mysterious substance in your body. Yang Zheng suddenly suggested at this time.

As soon as Chen Fan's mind moved, he immediately activated his divine sense and shot out a fierce ice blade, which quickly turned into a huge ball of light, shrouding Chen Fan in blood.

At the same time, every meridian on Chen Fan's body had a divine sense flowing through, and so on, Chen Fan frowned, and suddenly screamed, inspiring a strange fireball from the palm of his hand.

This fireball was only the size of a palm at first, but it gradually grew larger, and finally formed a large fireball of more than one zhang, and inside the fireball, Chen Fan could faintly see a trace of strange black aura, which was wandering non-stop.

Chen Fan roared and slapped an ice blade, and suddenly the fireball shrank a lot, turning from red to a strange black, and gradually landed on the dust in front of Chen Fan.

As soon as the fireball landed, all of a radius of trees, flowers, and insects were all dead in this instant.

"Ah......h

It turned out that the power of this fireball fluctuated too much, and it actually killed a martial artist who passed by inadvertently in an instant, you must know that the martial artists in the Heavenly Wolf Valley are all cultivated in the Martial Emperor period, and those who can achieve a one-move instant kill, except for Chen Fan, there should be no second person in the Fengqi Empire.

"This, what the hell is this?" Chen Fan looked at the fireball and fell into deep contemplation.

"In the old man's guess, it should be a new substance derived from the aura in the body after a great change, it seems that this substance is extremely domineering, and it can instantly kill any martial artist of the same level of cultivation, even if it is a martial artist who cultivates in the martial king period, I am afraid it is not easy to resist. Yang Zheng said.

"Well, it seems that this should be the most powerful magic weapon I have refined myself, so let's call him the Death Holy Light!" Chen Fan stared at the fireball and said with an unmoving expression.

"However, although the power of this fireball is great, it is still not enough to defeat the six demon elders, you can try to see if you can refine more fireballs. Yang Zheng said resolutely.

Chen Fan immediately shot out an ice blade, and it took a few more hours to finally refine the second Death Holy Light, but at this time, his body had lost a lot of energy, and he was already in a weak state.

He had no choice but to get out of the cave and go to find a martial artist to devour, so as to replenish the spiritual energy loss on his body.

And at the end of the day, a total of ten martial artists were forcibly devoured by him, with the abundant aura of these ten martial artists, Chen Fan began the trial of the third fireball, but the strange thing is that I don't know why this fireball can only be cultivated into two, if there is a third fireball, the first fireball will disappear immediately.

"This, what's going on?" Chen Fan was puzzled.

"Boy, there's a spike in any matter, but you can try fusing two fireballs together and see if you can refine a third ball of light. Yang Zheng said.

Chen Fan's mind moved, without saying a word, he immediately activated the gravitational hand, only to see a big hand pinch the two fireballs, and then gently collided together, only to hear a loud bang, the cave was dusty, Chen Fan waved the dust in front of him, and saw a brand new fireball placed in front of him.

This fireball was noticeably redder than the previous fireball, and its light was even more brilliant, and the moment it was born, the entire surface of the cavern was turned into an incomparably hard frost.

This caught Chen Fan off guard, and he couldn't help but fight two cold wars.
