After searching for more than ten days, Chen Daoqing finally found a good place, where there was not only a strong death qi, but also an extremely strong demon realm origin qi, and Chen Daoqing began to choose to retreat.

Chen Daoqing was not stabilizing his realm, but refining the Heavenly Demon Sword.

In the Jiuding Qiankun diagram, the endless origin qi rushed into it, and the void burned into a fire dragon, and the three treasures burned at the same time.

With the huge Origin Qi, it was too late to refine a treasure tripod, and all of the hundreds of immortal weapons had to be melted and re-refined, becoming the materials for the promotion of the Heavenly Demon Sword.

Chen Daoqing refined all the immortal magic weapons he had obtained from the tomb of the Ghost Judgment Emperor, and he wanted to completely give birth to the body of the Heavenly Demon Sword.

The Heavenly Demon Sword is a fallen artifact, and it has suffered heavy losses in the Creation War, but no one expected that after tens of thousands of years, he would be reborn again, and he would condense a new weapon spirit, which is simply unimaginable.

Chen Daoqing used three treasure tripods to refine the Heavenly Demon Knife at one time, only to feel that in the Heavenly Demon Knife body, countless formations seemed to be about to be refilled.

"Ling Tian, help me open the formation inside the Heavenly Demon Sword!" Chen Daoqing roared angrily.

The Heavenly Demon Son is just a tool spirit in the Immortal Realm, he can't fully control such a domineering Heavenly Demon Knife, he can't fully digest it at all by fusing so many materials at one time, he can only use the power of the outside world as an auxiliary, and Ling Tian has a fanatical love and understanding of the formation, so he is helping the Heavenly Demon Son control the formation that originally existed in the Heavenly Demon Knife.

The formation in the Heavenly Demon Sword is the same as the formation in the Jiuding Qiankun Diagram.

In fact, the structure of these magic weapons is composed of formations, otherwise it would be difficult to condense such a huge amount of energy.

The reason why these magic weapons are powerful is that the endless breath destroys the power of the formation, and then condenses together, slashing out endless power out of thin air, bombarding the other party.

However, the more powerful the magic weapon, the simpler the formation, and of course the more vast and majestic the formation.

Just like the Jiuding Qiankun diagram, there are countless magic weapons hidden in it, but the real hub has a total of three formations, the Eternal Star Bridge, the Flat Boat on the other side and the three large formations of the Qiankun Canghai.

There is only one formation in the Heavenly Demon Sword, the Heavenly Demon Disintegration Array!

However, it seems that the damage was very serious back then, hundreds of immortal artifacts were integrated into it, and although the quality was constantly improving, it seemed that there was still some gap if you wanted to upgrade to Zhongyuan immortal artifacts.

Chen Daoqing still underestimated the quality of the Heavenly Demon Knife, and it still couldn't be perfected in such a vast project.

At this moment, Chen Daoqing suddenly threw Yang Qianhua's body into the treasure tripod.

Suddenly, this magic weapon comparable to the peak state of the Xia Yuan Immortal Weapon, which was only half a step away, fused into the Heavenly Demon Sword Formation.

"It's not enough, it's not enough!" Ling Tian roared.

"Give me fusion again!" Chen Daoqing was a little completely crazy at this moment.

Suddenly, another Zhongyuan Immortal Weapon suddenly appeared in his hand.

It turned out to be a Zhongyuan immortal weapon from the Tianyi Sect disciple Tingfeng, although Chen Daoqing was a little reluctant, he still made an important decision.

Bang!

A Zhongyuan Immortal Weapon was directly shattered, and suddenly the Heavenly Demon Knife began to show signs of promotion.

Endless Origin Qi was filled with it, but it was a pity that after so many magic weapons were fused, the Heavenly Demon Sword still didn't have it

There are promotions, and the heat is slowly dissipating.

"It's not good! if you don't succeed, all this will be wasted!" Ling Tian roared.

"It seems that it is the only one!"

Chen Daoqing let out a long roar, and then sacrificed a Heavenly Demon Holy Banner and fused directly into the Heavenly Demon Knife.

The endless flames couldn't dissolve the Heavenly Demon Sacred Banner at all, but there seemed to be some kind of connection between the Heavenly Demon Holy Banner and the Heavenly Demon Sword, and at that moment, he received a will from the underworld, and it actually sank into the Heavenly Demon Blade Body.

Suddenly, a roar resounded throughout the space, and the Jiuding Qiankun diagram shook with it, and Chen Daoqing felt that he was about to be unable to suppress it.

Everyone's power is assisting Chen Daoqing to suppress this space.

"Ghost Zero Marshal, Stabilize the space!" Chen Daoqing shouted excitedly.

Ghost Zero was meditating on everything now, when he suddenly received Chen Daoqing's shout, and suddenly a powerful force began to stabilize this space.

Although he didn't know what was going on, this was in the Jiuding Qiankun diagram, without Chen Daoqing's instructions, he really didn't go around to peep.

With the fusion of the Ghost Zero Power, Chen Daoqing finally didn't have to be distracted to stabilize the overall situation, but instead concentrated all his energy on the Heavenly Demon Knife.

It seemed to condense into a huge storm on the Jiuding Qiankun diagram, and this storm frantically swept through the entire space with the Origin Qi surging towards Chen Daoqing frantically, and even directly evacuated the Origin Qi within a radius of tens of thousands of miles.

The Origin Qi required for the promotion of the Heavenly Demon Sword was too huge.

This is also the reason why it has been too difficult to improve the quality of the Heavenly Demon Knife all along, and it is precisely because the damage is too large that many basic formations have been shattered.

This time, Chen Daoqing repaired them all, and the Heavenly Demon Sacred Banner at this time was not refined, but became one of the eyes.

Because there is only one large array in the entire Heavenly Demon Knife, there is an array eye in it, and at that time, the weapon spirit of the Heavenly Demon Knife should be a master at the level of the Immortal Monarch, so there is only one array eye, which is controlled by the instrument spirit, which is more effective than the blessing of countless masters.

But now it's different, the power of the Heavenly Demon Son is only the peak of the immortals, and he can't completely control the formation eye, and when he encounters a super master, he will be the first to be unable to resist.

Therefore, with the help of Ling Tian's arrangement of the formation this time, Chen Daoqing actually began to scatter the formation eyes in the body of the Heavenly Demon Knife, and the Heavenly Demon Knife, which originally had only one formation eye, turned into one hundred and eight formation eyes at this time.

One of the main formations had been suppressed by the Heavenly Demon Holy Banner, and suddenly, the quality of the Heavenly Demon Sword began to rise and sublimate wildly.

"Zhongyuan Immortal Artifact !!"

Chen Daoqing roared angrily, and the quality of the Heavenly Demon Sword directly transformed!

From a lower yuan immortal weapon to a middle yuan immortal weapon, the strength has been churned hundreds of times!

Or now it can't be called a Zhongyuan immortal weapon, but a Zhongyuan magic weapon.

Chen Daoqing didn't dare to imagine that the Heavenly Demon Knife, which had achieved the Zhongyuan Demon Weapon, had surging power, as if it could be released in an instant, and it could be slashed down with one sword, which could directly make a master at the peak level of an immortal have nothing to hide, and directly bombarded and killed.

This kind of unparalleled power is unbridled, bringing infinite surprise and surprise to Chen Daoqing.

"Hahahaha!" Chen Daoqing laughed wildly: "Finally succeeded!"

Chen Daoqing used another Zhongyuan Immortal Weapon, plus a Heaven with the potential of a person's treasure

Immortal masters, as well as hundreds of Lower Yuan Immortal Weapons, have finally improved the quality of the Heavenly Demon Knife to the Middle Yuan Demon Weapon.

From now on, if you are facing a master of Shura, even a six-star Shura will be clamped down by the Heavenly Demon Sword.

The six-star Shura is the realm of the Heavenly Immortals, and even the peak of the Heavenly Immortal Realm, the master of the little gold level.

Originally, the Heavenly Demon Knife had restraint on any Hell Demon Clan, but now it is good that Chen Daoqing has successfully refined the Central Plains Immortal Weapon in the Demon Realm, which is absolutely unimaginable.

Even in the entire Demon Realm, there are very few imitations of the Heavenly Demon Sword that are refined into medium-grade immortal weapons!

Chen Daoqing had just come to the Demon Realm and had not been many years ago, and he directly promoted the Heavenly Demon Sword to the Zhongyuan Immortal Weapon, which could be said to be the first person in the ancient world.

There was such a huge commotion here, which directly alarmed the super masters of the Bloody Hand Pavilion, and their divine thoughts were all scanned here.

Chen Daoqing frowned, then turned into a speck of dust, and fled to the Jiuding Qiankun diagram along with himself.

The small world of Jiuding Qiankun Diagram floats in the void, looking for another address again.

"Young Master, were you refining the Zhongyuan Immortal Weapon just now?" Ghost Zero asked curiously.

"Yes!" Chen Daoqing nodded, he was a little curious, Ghost Ling didn't even have a real magic weapon on his body.

"It's a pity that my natal magic weapons were destroyed in the battle. "Ghost Zero seems to be a little sorry.

"As long as we wait patiently for the Emperor to return, everything will be recaptured!" Chen Daoqing said firmly.

Actually, what he said is not untargeted, if the Ghost Judgment Emperor returns, in the entire Demon Realm, unless the Chiyuan Heart Demon appears again, there is really no one who can compete with the Ghost Judgment Emperor.

The big names at the beginning have all disappeared in the long river of history, and no one knows where they went, or they have already fallen.

Chen Daoqing is very curious, but also very delicate, although the relationship between him and Ghost Zero is strange, but it is not-for-tat.

Chen Daoqing deliberately went to have a good relationship with Ghost Zero.

Because it is really too important for a big man to sit in the Jiuding Qiankun Diagram, just like just now, if there is no ghost zero shot, the entire Jiuding Qiankun Diagram will almost destroy more than half of the big array.

Chen Daoqing opened a gap, and Ghost Zero could continuously absorb the dead qi into it.

Ghost Zero also saw that this was a complete small world, which made him even more convinced that this was a disciple of the Ghost Judgment Emperor, otherwise how could he even control such a magic weapon.

"Ghost Zero Marshal, the demon world is chaotic today, and I need a big man like you to support me, so sometimes I still need you to take action. Chen Daoqing said cautiously.

"Young master, rest assured, I will definitely clear any obstacles in the way of the young master. Oni Zero said arrogantly.

Chen Daoqing smiled, feeling that Ghost Zero was a little different from other masters in the ghost world, he was a little stupid, no wonder he didn't become the personal guard of the Ghost Judgment Emperor back then.

Chen Daoqing clearly felt several breaths sweeping over his body, but he didn't find his location.

Unconsciously, more than 20 days have passed, and Chen Daoqing has been floating like this.

It's not that he really doesn't want to kill anything, but this ancient battlefield, I really don't know how many big people have been swept by the Demon Palace, almost everything in it has been excavated, Chen Daoqing has encountered several places like tombs, but they have all been swept away, and there is nothing.
