The interior of the Dark Thunder Prison was filled with terrifying thunder and lightning and dark power, affecting the space inside, which was a bit chaotic, making Chu Duan's plan to use the mystery of emptiness to perform a reverse air step to get out of trouble.

After all, although the mystery of emptiness has been refined to the limit of the ninth revolution, the application of the mystery of emptiness is not deep enough, and so far Chu Duan has not created a sword technique based on the mystery of emptiness.

The sword slashed out, the gold and cyan fused, and a sword slashed out.

Human-level second-grade ground-breaking sword technique: Slash the wind!

In terms of power, among the various human-level second-grade sword skills that Chu Duan mastered, the power of slashing wind was the strongest.

All kinds of sword skills are a combination of sword intent and mystery, released in a unique way, thunder and fire killing, hot wheels, are all the same, the same is true of the sword skill of cutting the wind, the only difference is in the shaking of the mountain.

Shaking Mountain Jin is a special kind of force, at least until now, Chu Duan has not been able to break through the air like a sword, there must be a bearing, and it must be an entity, the energy body can't do it, and it will collapse as soon as it is carried.

Therefore, the Wind Chopping Sword Technique is a sword skill for melee combat, of course, if it is not integrated into the mountain shaking power, the Wind Chopping Sword Skill can also attack from a distance, but the power is not so strong (there may have been some written before, the long-distance sword skill contains the power of the mountain shock, that is a mistake in my thinking, correct it here).

Under the extreme shaking power, the edge of the sword without returning, and the ultra-high frequency shock, its cutting power reached a terrifying level.

Like a chainsaw splitting into an iron pipe, countless sparks flew away, and the fence of the Dark Thunder Prison trembled, and the black thunder light on it shook.

The three of them just smiled disdainfully, ignored it, and continued to condense the curse seal, in their opinion, Chu Duan was just doing a battle of trapped beasts.

"It's so strong!" Chu Duan was shocked by a powerful force, both the power of thunder and lightning and the power of darkness, and was shattered by him.

"If you use the three-grade sword technique, you may be able to break it with one sword, but the three-grade sword technique I created seems to be not suitable for such a performance. Chu Duan was a little helpless, the three-grade sword technique he had newly created was not perfect enough, and it had not been combated, it was certain. The power is definitely stronger than the slashing wind, but if you use it in such a narrow environment, you are likely to hurt yourself.

Sword skills are not set not to hurt anyone, once it is affected, it will be affected, unless, the control of sword skills has reached an unpredictable god-like level, at least for now. Chu Duan thought he couldn't do it.

Since this is the case, let's continue to use the slashing wind, and the no-return sword will be slashed out again, and the sword will be slashed at the position of the first sword.

Chu Duan's speed of swinging his sword was extremely fast. His continuous bursts at the limit entry are amazing, and he can also achieve continuous bursts when he uses his sword skills.

Every time the sword slashes the wind, the fence of the Dark Thunder Prison that was slashed by Chu Duan will definitely shake once. The frequency is getting bigger and bigger, and gradually, it makes the three evil spirits feel bad. If he continues, he will likely be cut out of the Dark Thunder Prison by Chu Duan, and it will be even more difficult to capture him alive at that time.

They want to speed up the condensation speed of the spell mark, but this is a king-level spell mark, it is already a little difficult for the three of them to cast it together, and it is even more impossible to speed it up, so they can only hope that they can cast the king-level spell mark before the dark thunder prison is cut by Chu Duan.

"Crush me!" with a loud shout, Chu Duan slashed out another sword.

This sword, the color is even brighter, slashing at the fence of the Dark Thunder Prison that is already gapped, with Chu Duan's indomitable will, a click sounds, and in the countless sparks splashing, one of the fences of the Dark Thunder Prison was immediately cut off.

The Dark Thunder Prison became incomplete, and the internal chaotic thunder and lightning and dark power poured outward, and at the same time, the geniuses of the three Hades Clan also completed the spell seal, let out a low cry, and pushed forward, and the three black curse seals flew towards Chu Duan in a swirling manner.

At the same time, Chu Duan raised his steps and stepped out.

Everything was like a movie in slow motion, and the three of them stared with wide eyes, hoping that the spell mark would fall on Chu Duan's body.

In an instant, the curse seal was imprinted on Chu Dui's body as he wished, but Chu Dui's body quickly faded, and it turned out to be just an afterimage.

"Shoot with all your strength and kill him. "The evil spirit immediately decided, Chu Duan is very strong, beyond the intelligence, he can no longer be captured alive, he can only be killed, although the value is lower, but it is better than letting Chu Duan escape.

Boom, boom, three voices sounded, and three terrifying momentum erupted from the bodies of the three evil spirits, causing the tomb to shake instantly, as if it was about to shatter.

Since he was able to kill Chu Duan, he had nothing to scruple about and went all out.

Chu Duan had no intention of escaping, his thoughts were the same as the other party, to kill the other party.

"Killing such a strong enemy can give my sword fetus a lot of nutrients. Chu Duan appeared outside the tomb, and the sword slashed out.

In an instant, in the passage of the ancient tomb, sword skills and spells collided continuously, and there was a big explosion, and terrifying energy of different colors vibrated away.

Chu Duan is just one person, and his opponent is three, three true geniuses of the Hades God Clan, each of which can be his opponent alone, especially the Underworld, the strongest strength, can completely threaten Chu Dui, so the battle with them is a battle on the edge of life and death, Chu Duan must concentrate and squeeze every bit of his potential.

Out of the sword, dodge, block, all the actions are naturally made, between the connections, the flow of clouds and water, more and more smooth.

The battle between life and death is the best way to train people.

This is also the first time that Chu Duan has used his strength to exert the Nine Turns of Sword Intent and Mysteries against the enemy, which is very enjoyable and incisive.

Finding an opportunity, Chu Duan brewed a little, and the three forces of the Mystery of the Wind and the Mystery of Fire and the Mystery of the Earth were infused into the Wuhui Sword, and the three forces began to merge under Chu Duan's control, and finally formed a new terrifying force force.

Instantly, in a unique way, Chu Duan swung out with a sword, and the new power disappeared in an instant, and then, at the feet of the three Hades Clansmen, it seemed that the phantom of a volcano appeared, and in an instant, the magma torrent that had accumulated for a hundred years erupted out.

A rumbling sound sounded, earth-shattering, terrifying magma torrents, with the posture of destroying heaven and earth, descended on the earth, and the hard ground of the stone tomb was also shattered in an instant.

The three-grade sword technique formed by the fusion of the nine-turn sword intent and the three nine-turn mysteries is a human-level three-grade heaven-shaking sword skill, and the power is incredibly powerful.

As soon as Chu Duan cast this move, which he named the Volcanic Explosion, the human-level three-grade heaven-shaking sword technique, the evil spirit already felt dangerous, a creepy feeling, which made him tremble all over, and even his soul trembled, without the slightest hesitation, he immediately dodged, and at the same time cast a defensive spell.

The other two Pluto geniuses reacted a little slower, a little, the difference between life and death.

Boom twice, the two Pluto geniuses who had been damaged by Chu Duan before were directly bombarded by the power of the volcanic explosion, from the bottom to the top, without the slightest ability to resist, just let out two screams, and they were torn apart in the terrible magma flames, and then they were burned by the high-temperature flames, quickly scorched black, and turned into charcoal.

The evil was also affected, but fortunately, he cast a defensive spell in time, and the defensive spell was broken, but he was unharmed.

"Hades God Law Phase!" Without hesitation, the Underworld Evil used the secret method of the Pluto God Clan, and a black Law Aspect appeared behind it, and a majestic heavenly majesty descended, enveloping the surroundings, making Chu Duan's body sink, and the flow of qi and blood was a little sluggish.

The evil god of the underworld is obviously stronger than the underworld, and it already has a trace of divine might.

Casting the evil of the Hades Divine Appearance, the overall strength has increased several times, and the spell is cast almost without delay, the hands are instantly sealed, and the spell is immediately cast.

The blue-black wind blade, the black-red fireball, and the purple-black thunder and lightning were as bright as fireworks, and they continued to bombard Chu Duan.

These spells were shattered one by one by Chu Duan's sword skills and counterattacked.

The evil condensed the spell mark again, a little slower, but it was a more powerful spell, a spell formed by the fusion of three forces, a whole black flame like a storm swept in, to burn everything on the way to ashes, there is a relationship between the god of the underworld, the power of this spell on the basis of the original, increased several times.

At the same time, Chu Duan once again unleashed a volcanic explosion.

The volcanic explosion collided with the spell of the Underworld, and the terrifying explosion completely shattered the ground of the ancient tomb, and countless cracks spread, scorching black and emitting green smoke.

The shock wave raged in all directions, and Chu Duan hurriedly cast a defensive sword technique: Ice Flow!

The Ice Flow is a human-level second-grade sky-shaking sword technique under the fusion of the mysteries of water and ice, forming a frozen cold current, which wraps around Chu Dui's body and resists the impact of the terrifying high temperature.

Under the impact, the ice stream clicked and shattered, and then melted, but it provided Chu Duan with enough buffer time to quickly retreat and avoid the shock wave, and on the other side, the evil also avoided the shock wave.

Chu Duan struck again, and it was still a human-level third-grade heaven-shaking sword skill volcanic explosion, but in this sword, a part of the power of the earth's core desolate flame was integrated, which made the power of the volcanic explosion much higher.

The extreme sense of danger made the soul of the evil spirit tremble, and he hurriedly cast a defensive spell, and then cast an acceleration spell and other auxiliary spells to improve himself and quickly break away.

The hard tomb floor shattered again, volcanoes emerged from the ground, and terrible torrents of magma erupted with a hint of bright yellow, destroying the world.

Under the shock wave of the volcanic explosion, the demon's defensive spell was directly impacted, and it was shaky, and the demonic also quickly retreated to open the distance, and the defensive spell on his body was broken, but the demonic did not suffer any damage.

Chu Duan couldn't help but secretly say that it was a pity, if it weren't for the Hades God Divine Appearance, the defensive spell would not be able to resist the power of the volcanic explosion at all, and even if the Hades were immortal, they would be hit hard.

However, it is also a good thing to have such a strong opponent to fight to the fullest. (To be continued......)
