Duan Chen didn't know anything about the Soul Devouring Flame, so when he saw that sword qi from Jian Wuya being devoured by the Black Firebird, he couldn't help but wonder and asked the Seven Demon Lords what was going on.

"That's the Soul Devouring Fire, which is specially researched by the Demon Race to deal with you Terran monks, this fire can devour all spiritual power and grow, and it is said that it can also devour magic and demon power, but the speed is very slow. The Seven Demon Lords explained casually.

Duan Chenqi said: "Even magic power and demon power can be devoured, so how to deal with it?"

Just in case, he felt it necessary to know the weakness of this Soul Devouring Fire beforehand, so as not to run into a scramble later.

The Seven Demon Lord muttered, "There are many ways, but the simplest is like Sword Boundless is now, just seal this Soul Devouring Flame directly." ”

Duan Chen raised his eyebrows when he heard this, and then turned his eyes to the center of the battlefield.

I saw that in the sky, after recognizing the origin of the Soul Devouring Flame, Jian Wuya immediately pinched the sword technique with both hands, urging the broken lotus sword diagram suspended above his head to meet it.

The black firebird slammed into the lotus sword diagram, and immediately disappeared into it in a flash.

At the same time, the fire flashed on the lotus sword diagram, and a lifelike black firebird appeared in it, surrounded by lotus flowers, motionless.

"Sealing magic weapons? I didn't expect that this sword diagram of Daoyou still has the ability to seal, but although the Soul Devouring Fire was sealed by Daoyou, this sword diagram of Daoyou can also not be used, and in the next third round of the competition, if Daoyou does not have this sword diagram to protect himself, I am afraid that it will be difficult to resist the attack of the stay. Zhu Yan Demon King glanced at the lotus sword diagram with some surprise, and then said with a smile.

With a wave of one hand, Jian Wuya put away the lotus sword diagram, and said with a slightly cold gaze: "There is no third round, and the next move will determine the winner and loser." ”

Zhu Yan Demon King was slightly stunned when he heard this, and was about to say something when he saw a purple rainbow flying sword flying out of Jian Wuya's mouth, landing on his palm, and turning into three feet long.

"Natal Flying Sword?" Zhu Yan Demon King saw the Zihong Flying Sword held in Jian Wuya's hand, and immediately realized that what Jian Wuya said was true, and it seemed that he really planned to divide the victory and defeat in the next move.

At that moment, he didn't dare to slack off with a pinch of the magic trick in his hand, and his body turned into a flame dragon with a body length of dozens of zhang in a burst of firelight, hovering in the sky.

But at the same time, in the body of Jian Wuya, who was holding the Purple Rainbow Flying Sword, a shocking sword intent rushed into the sky, and his long white hair, which was originally tied behind his head, spread out, and then saw him wave his arm, and a sword roar resounded through the void.

The next moment, everyone's faces changed, and even the eight Yuan Infant Cultivators who were watching the battle on both sides showed a hint of shock on their faces at this time.

No one could see how Jian Wuya swung this sword, people only saw the sword light in Jian Wuya's hand flashing, and an incomparably thick and condensed purple sword light flew out from the purple rainbow flying sword in an instant.

I saw that where the purple sword passed, the void was like a tide splitting to both sides, half rising upwards and half falling downwards, looking from a distance, as if it was opening up the heavens and the earth.

How is this possible?

When the Demon King of Zhu Yan, who had just revealed the true body of the demon clan, saw this scene, the pupils in his eyes shrank, and then he immediately waved his two huge claws to pinch out a magic trick, and then opened his mouth to spit out

A fist-sized multicolored crystal bead is produced.

This is the natal magic weapon of the Zhu Yan Demon King, and in the face of the amazing momentum of the sword swung by Jian Wuyan, he does not dare to hide the slightest clumsiness.

But after seeing the multicolored crystal beads flying out of the mouth of the Zhuyan Demon King, they immediately released streams of colorful flames.

The flames rose, and in the blink of an eye, the void within a radius of 100 zhang immediately turned into a sea of fire, and within the scope of the sea of fire, volcanic phantoms rose from the ground, spewing thick smoke and magma, and swept in all directions.

Duan Chen's face was full of shock, and the Nangong Ancestor, whose figure was suspended beside him, showed a hint of longing in his eyes, and muttered to himself, "Is this the real spiritual realm?"

Although he has broken through to the peak of Jindan, until now, he has not even comprehended the pseudo-spirit realm, and at this point, the master of the four rings in the later stage of Jindan has to walk ahead of him.

After all, when Duan Chen visited Qingyun Temple at night, he had seen the Master of the Four Rings use the pseudo-spiritual realm.

However, whether it was a pseudo-spiritual domain or a real spiritual domain, Duan Chen didn't know much, he just knew a name and a general idea.

At that moment, he couldn't help but secretly send a message to ask the Seven Demon Lords for advice.

The Seven Demon Monarchs knew everything, and patiently explained: "The so-called Spirit Domain, also known as the Demon Domain or the Demon Domain, to put it bluntly, is a manifestation of the release of mana, which involves many aspects, and can only be comprehended when the realm of the Dao reaches a certain level. ”

"Can the mana release spread over such a large area?" Duan Chen looked at the vision in the sky and was taken aback when he heard this: "Even if the mana in the Yuanying Monk's body is released at one time, it can't cover a radius of a hundred zhang, right?"

Duan Chen only knew that the release of mana could form a protective shield outside the body, but this not only consumed mana, but also enveloped a very small range, depending on the amount of mana in the monk's body.

"The so-called spiritual realm is not as simple as the release of mana. The Seven Demon Lords said lightly: "The simple release of mana, not to mention the Yuanying Monk, even the higher realm of the Transformation Cultivator, can not maintain the release of mana to support the existence of the spiritual domain for too long, even if all the mana in their bodies is drained, it will not be able to do it." ”

Duan Chen raised his eyebrows and said, "In other words, there are other things supporting the operation of the Spirit Domain?"

The Seven Demon Lords glanced at Duan Chen approvingly, and then said, "Yes, when the manpower is poor, even the Yuan Infant Transformation Divine Cultivator can't simply rely on mana to form a spiritual domain, so they need to rely on external forces. ”

Duan Chenqi said: "What external force?"

The Seven Demon Lords smiled faintly and said, "Don't always know how to ask why, learn to think with your brain, you can guess for yourself first." ”

Duan Chen didn't expect that the Seven Demon Lords would still be in the mood to test himself at this time, and immediately muttered: "You can't rely on mana alone, you also need to rely on external power, when you just said that manpower is poor, and you said that you can only comprehend it when you reach a certain level in the realm of the Dao......

Duan Chen muttered to himself, his thoughts became clearer and clearer, and then he blurted out: "Isn't the external force that the predecessor said mean the power of heaven and earth?"

The Seven Demon Lords nodded with satisfaction and said with a smile: "You can teach, yes, if you want to maintain the operation of the spiritual domain, it is extremely difficult to rely on your own strength, but the power of heaven and earth is inexhaustible, if you can know how to mobilize the power of heaven and earth, it will be much easier to form and maintain the operation of the spiritual domain." ”

Duan Chen probably understood a little, and then asked, "Then how do you mobilize the power of heaven and earth?"

Hearing this, the Seven Demon Lords sneered and said: "You haven't even broken through the Jindan now, your cultivation is not enough, even if I tell you, it's in vain, in short, if you want to cultivate into the spiritual realm, wait until you break through to the Jindan." ”

Duan Chen didn't blush at all because his purpose was exposed, and he pondered for a moment and asked, "In other words, Monk Jindan will be able to cultivate the Spirit Domain?"

The Seven Demon Monarch shook his head and said: "How can it be so simple, only the Yuanying Monk can cultivate the spiritual domain, and it would be good for the Jindan monk to cultivate the pseudo-spiritual domain like that four-ring bald donkey, but then it will only touch the threshold of the spiritual domain, and there is still a long way to go before cultivating into the real spiritual domain." ”

Duan Chen nodded and asked a very realistic question: "Senior, if I am now facing a Jindan monk who has cultivated into a pseudo-spiritual realm like the Master of the Four Rings, can I escape?"

"It depends. The Seven Demon Lords said: "If the distance is outside the scope of the opponent's pseudo-spirit domain, as long as your speed is faster than the other party's, you can naturally escape easily, but if it is within the scope of the opponent's pseudo-spirit domain, it will be troublesome." ”

"Trouble?" Duan Chen's heart moved, and he noticed that the Seven Demon Lords were talking about trouble, not death.

The Seven Demon Lords opened his mouth and explained: "Whether it is a pseudo-spiritual realm or a spiritual realm, even if you can mobilize the power of heaven and earth, it is still too much of a burden for the monk, here we take the four-precept bald donkey as an example, if he uses the pseudo-spiritual realm, the mana in his body can probably only support about fifteen breaths, if you can survive these fifteen breaths, you can even turn defeat into victory." ”

"But generally speaking, if the use of the pseudo-spiritual domain cannot distinguish the winner from the defeat, no one will always maintain the operation of the pseudo-spiritual domain. ”

When Duan Chen heard this, he immediately understood that the mana consumed to maintain the operation of the pseudo-spirit domain was even greater than he had imagined, and the late-stage Jindan cultivators could only support fifteen breaths.

Bang!

At this moment, there was a loud roar in the sky in the center of the battlefield, and the purple sword light that Jian Wuyan slashed out suddenly skyrocketed from more than ten zhang in size to hundreds of zhang in size, and slammed into the volcanic sea spirit domain opened by the Zhuyan Demon King.

At that moment, the entire Volcanic Sea Spirit Domain suddenly shook wildly, and then a crack appeared on the multicolored crystal bead suspended in the center of the Spirit Domain.

Seeing this, Zhu Yan Demon King's face froze, and then he opened his mouth and spewed out a ball of essence blood, which instantly burst open, turned into a blood mist, and submerged into the colorful crystal beads.

Then, the Volcanic Sea Spirit Domain, which originally seemed to be crumbling, became stable again after the multicolored crystal beads absorbed the blood mist.

Zhu Yan Demon King secretly breathed a sigh of relief.

However, at this moment, the purple sword that was more than a hundred feet long suddenly exploded open, and a spiritual realm filled with endless sword qi suddenly descended on the Volcanic Sea Spirit Domain, and slammed into it.

Then I saw that the Volcanic Sea Spirit Domain, which had just re-stabilized, was immediately shattered in a roaring earthquake, and the multicolored crystal beads suspended in the Volcanic Sea Spirit Domain had four or five more cracks on the surface, as if they might burst open at any time.

And almost at the same time, Zhu Yan Demon King's huge dragon body couldn't help but open his mouth and spew out a mouthful of blood with a muffled snort.
