The strongest head exchange system

Chapter 712
In the abyss, several bursts of devilish energy exploded, shaking the entire space.

Yan Xu's eyes turned cold. It turned out that the muffled sound from the ground that he heard earlier was not only the sound of Mu Han fighting with monsters, but also the devilish energy in the abyss.

The blade of the Scarlet Emperor Sword in the center of the magic circle issued bursts of sword whistling and whistling, and once again pushed the magic pressure back into the abyss.

The magic energy was temporarily suppressed, but a few new cracks appeared in the magic circle. I'm afraid that it won't be long before the sealing magic circle completely dissipates.

With stern eyes, Yan Xu dived down the abyss to see what happened below.

The demonic energy in the abyss was surging, and the temperature was unimaginably low, Yan Xu shivered involuntarily.

Seal the forbidden zone.

In the middle of the abyss, there were huge four characters engraved on the thick stone wall, and Yan Xu leaned over carefully.

Suddenly, the words "Sealing Demons Forbidden Zone" disappeared, and a huge projection appeared on the stone wall.

In the projection, a white-robed man fought fiercely among the demons like a god king, exterminated the demons with one breath, and finally broke into an underground lair of the demons outside the sky.

The golden light surged all over the body of this white-robed man, and he looked down on his true face, but who else could there be except Immortal Emperor Chiming.

The extraterrestrial demons are very cunning. The lair they built is connected to the source of law in Luotian Continent, and they are constantly absorbing the power of the law from the source.

Immortal Emperor Chiming didn't dare to attack with force, if the origin of the world was injured, the whole world would collapse.

At the end of the screen, Immortal Emperor Chiming used the artifact Chidi Sword as a guide to arrange a large formation to seal the demonic lair of the extraterrestrial demons, and this large formation evolved into the Wanxu Mountain Range.

The projection on the stone wall gradually disappeared, and the four characters of "Forbidden Demon Sealing Zone" reappeared.

In addition to this picture, Yan Xu also got a piece of text information.

There are two places in the Forbidden Land of Demon Sealing.One is in the northern border of Luotian Continent, that is, this place, and the other is in the southern border of Luotian Continent.

In the Forbidden Land of Sealing Demons, the main force of the real army of evil spirits from beyond the sky is sleeping, and many of them are demon leaders who have passed through the catastrophe.

They were seriously injured by Immortal Emperor Chiming, and they huddled deep in their lair. Due to the threat to the origin of the world, Immortal Chiming could not kill the grass and roots.

Yan Xu stared blankly at the endless abyss below, and sighed:

"Immortal Emperor Chiming can only seal this place. I'm courting death if I go in now. The most troublesome thing is that the sealing formation above won't last long. We must find a way to stabilize the formation. It's over."

Yan Xu did not continue to explore, turned back to the upper method circle, and circled around the method.

Mu Han was already awake, so he stepped aside so as not to interrupt Yan Xu's thoughts.

"Although this magic circle may collapse at any time, it has provided me with a clear idea. As long as I follow its rules, maybe I can rebuild a large sealing circle."

Yan Xu was frowning at first, but after thinking for a long time, he finally got some clues, and his brows gradually relaxed.

What is the realm of Immortal Emperor Chiming? He said that the magic circle he arranged was so profound, but Yan Xu slowly digested it bit by bit, and gained a deeper understanding of the way of the magic circle.

There are not many opportunities to study the handwriting of the Great Emperor, and Yan Xu will never let it go.

"This magic circle is very mysterious, you should also come to understand it. But remember, you must do what you can, and you must not force it to be deduced, otherwise your spiritual consciousness will be seriously injured."

Yan Xu said to Mu Han, although it is too difficult or even impossible for a cultivator in the distraction stage to comprehend this formation, after all, Immortal Emperor Chiming is his previous life, and it is not certain that he may be able to gain something.

Mu Han nodded, felt dizzy after just one glance, and almost couldn't stand up.

Mu Han took several steps back, closed his eyes and adjusted his breath for a while before recovering, opened his eyes again and only dared to look from the weakest edge of the magic circle.

Seeing that Mu Han was fine, Yan Xu concentrated on studying the magic circle again, and made calculations at a high speed in the sea of ​​knowledge.

Rumble!
Below the magic circle, the devilish energy in the abyss struck again, and with each surge of devilish energy, the edge of the magic circle was bit by bit eaten away.

Yan Xu has to race against time, once the magic circle completely collapses, not only will he not be able to figure out the principle of the magic circle, but also the devil in the abyss will wake up with the break of the circle.

Yan Xu stood above the magic circle and went all out without moving. Mu Han simply gave up on studying the magic circle and stepped back to protect him from the magic energy entering his body.

After three days and three nights, Yan Xu finally moved, took out the endless sword box and inserted it into the center of the magic circle without hesitation.

hum!
The magic circle stirred for a while, and the formation pattern emitted a dazzling light, which then dimmed in an instant.

"If you can't break it, you can't stand it! To re-seal the demons, you must rebuild this formation!" Yan Xu's eyes were extremely firm, and he pinched out a formula with both hands.

Before the magic circle was completely dimmed and extinguished, flying swords flew out of the endless sword box, and according to the direction Yan Xu pointed, the flying swords inserted into the magic circle.

Every time a flying sword is inserted, the array patterns in the corresponding area brighten up again, and the power of the magic circle recovers a bit.

In just a few breaths, thousands of flying swords filled the entire formation, and the formation was completed!

"Take it!" Yan Xu yelled lightly, and took away the blade of the Scarlet Emperor Sword floating in the center of the magic circle.

"I use the flying sword of the endless sword box to rebuild the foundation of the magic circle, and the Scarlet Emperor Sword can no longer stay here, otherwise the two treasures will conflict with each other, which is not good."

Yan Xu wiped the fine beads of sweat on his forehead. It seemed relaxed just now, but it was actually quite thrilling.

As long as a flying sword is inserted in the wrong place, the whole game will be lost. Yan Xu did not dare to be careless at all, and now he can finally breathe a sigh of relief.

"Put away the sword body, and find an opportunity to recast them into one body later." Yan Xu threw the sword body of the Scarlet Emperor Sword to Mu Han.

Mu Han caressed the blade lightly, feeling an inexplicable sense of familiarity, and then carefully put it away, "Thank you, Master!"

Yan Xu nodded, and then looked at the sword formation just set up.

The Scarlet Emperor Sword is a third-tier artifact, and the Endless Sword Box is only a first-tier artifact. In terms of coercion, the Endless Sword Box is not as good as the Red Emperor Sword, even if it is just the body of the Red Emperor Sword.

However, the endless sword box also has an advantage, that is, the number of flying swords stored is infinite, and it can win by number.

Yan Xu mastered the principle of Chiming Immortal Emperor's sealing formation, calculated 99 formation eyes, replaced the formation eyes with the same number of flying swords, and guarded the center with endless sword boxes, and then rebuilt a sealing formation.

"Fortunately, Immortal Emperor Chiming sealed this place with a large array of sword energy. If I used other means, I might not have an alternative." Yan Xu said happily.

Rumble!
The demonic energy in the abyss surged, and the eight thousand nine hundred and ninety-nine flying swords trembled suddenly, and the demonic energy and the sword array were colliding with each other.

After dozens of breaths, the demonic energy finally died down, Yan Xu heaved a sigh of relief, the sealing effect of the sword array has withstood the test.

Snapped!
In the center of the magic circle, a flying sword suddenly shattered, and the fragments scattered all over the ground.

Yan Xu's face changed slightly, and he secretly said: "Xuantian Lingbao-level flying sword is really far behind!"

clap clap clap!
There were a few more crisp sounds, and several flying swords shattered in succession. First, they were injured when fighting against the demonic energy.

"It's a good thing I was prepared, otherwise, this sword formation really wouldn't last long." Yan Xu smiled wryly and shook his head, the sword formula pointed to the endless sword box, and a few bright flying swords flew out of the sword box , to replace the flying sword that just collapsed.

Yan Xu fell to the center of the sword formation, and set up a small magic circle around the endless sword box.

Under the control of this small magic circle, even if no one is guarding it, the endless sword box can automatically replace the damaged flying sword. At least for hundreds of years, there will be no problems with the forbidden sword circle.
