It's just a pity that they don't have the eyesight to recognize the invisible yin thunder, and naturally they can't understand the vicious thoughts of Li Zun and the demon king.

Boom Boom!

Thunderbolts thundered on a sunny day, and dozens of thunderbolts exploded out of thin air.

The many underworld monks and demon beasts that flew out in all directions, and more than a dozen figures immediately fell from the sky, and there was no sound again.

The surface of these people's bodies was shrouded in a layer of purple thunder, and their flesh was already charred black.

The Lei Fa that the Yuanying Monk could barely carry was a second kill for the Jindan Monk and the Sanpin Demon Beast!

This scene made the other people who were moving a little slower tremble in fright, and they didn't dare to flee anymore.

But for Li Zun, that's enough.

Because with the sacrifice of these dozen lives, he has discovered the gap of the invisible yin thunder.

In the three directions of northwest, southeast and due south, there is no arrangement of invisible clouds.

The three monks and the two demon beasts who chose these three directions to escape were already about to escape from the valley.

There are three gaps in total, and you and the two demon kings of Wolf Palace and Jackal Li can just choose one of each and scatter and escape.

Li Zun thought in his heart.

It's just that the next moment, his complexion changed.

Because at those three gaps, there were shining sword lights and extremely fluctuating spells that suddenly appeared, attacking the fleeing underworld monks and demon beasts.

......

Not so long ago.

The Northern Soul True Venerable covered the breath of everyone, quietly watching the Demon Spirit Palace and the Underground Mansion fight in the form of a fisherman, and at the same time released one after another invisible yin thunders, preparing to use the invisible yin thunder to quietly besiege this valley.

It's just that the battle between the three demon kings in the valley and Li Zun is progressing too fast, and before he has sealed all the retreats, Li Zun is already trying to escape here with the help of the magic objects given by the Void Devil.

In this case, the Northern Immortal True Venerable could no longer watch the fire from the other side, and immediately thundered and stopped Li Zun.

"I haven't had time to lay down the thunder law in the northwest, southeast, and due south directions, and it is a vacancy, so I will leave it to the three of you to guard.

This time, there is no room for error, I want everyone in this valley, whether it is the underworld monk or the demon beast of the Demon Spirit Palace, not to think of leaving. "At the moment of the shot, the Northern Soul True Venerable immediately transmitted a message to the three high-level members of the Lingxu Building, namely Shantai Qingrun, Sha Shuyan, and Xian Huaibi, and asked them to each be responsible for guarding a gap.

The scene was chaotic, and the momentum of the Northern Darkness True Venerable was too great, attracting most of the attention of the underworld monks and demon beasts in the field, plus the three of them deliberately concealed their aura, so Li Zun didn't notice the existence of these three people for a while.

It wasn't until now, when the three monks used their own means to intercept the underworld monks and demon beasts of the Demon Spirit Palace who wanted to escape from the valley, that he noticed the existence of the other three monks.

In the northwest direction, where the Qingrun town of Shantai was guarded, two underworld monks chose to flee here at this time.

Yutai Qingrun snorted coldly, and the two natal swords of Lingyin and Qiu Hong came out together.

At this moment, in the eyes of the two dungeon monks, there were two sword lights across the sky.

The fierce sword qi accompanied by the unique waning moon sword light of the Lantai family, attached to the sword weapon, set off the two flying swords like a dream, and slashed towards the two underworld monks who were coming at them.

The face of the monk of the underworld changed abruptly, because the speed of the two flying swords sent out by the Qingrun of the Underground was too fast!

In just the blink of an eye, the sword light had already reached the eyes of the two of them.

One of the underworld monks sacrificed a trident magic weapon to resist, while the other underworld monk hurriedly cast a defensive spell to meet the flying sword.

Boom!! Boom!!

The terrifying power made the body of the underworld monk holding the trident magic weapon so shocked that he involuntarily took several steps back, and the spiritual power in his body violently stirred.

The situation of the Underworld Monks who cast defensive spells was much worse.

Qiu Hong's sword instantly slashed through the rock shield he had cast, and bombarded him with undiminished power.

Even though he was urging the body protector to resist it at the first time, under the powerful impact of Qiu Hong's flying sword, his entire body still flew upside down, and he was still spurting blood in the air.

Sou!

At this moment, another huge explosion suddenly came out, attracting the eyes of Qingrun.

As a sword cultivator, this voice was very familiar to her.

It was the sonic boom produced by the flying sword after it reached the first level of sonic realm.

However, among the three monks present, in addition to her, Sha Shuyan, the master of the Lingxu Building, is a Yuanying cultivator who is proficient in the art of the earth, and Xian Huaibi, the deputy owner of the building, is a Jindan body cultivator, and there is no second sword cultivator at all, where does this flying sword come from?

As for Lu Qingshan, she did think about it.

But how could a flying sword in the sound speed realm be able to be unleashed by a foundation-building monk?

A red light burst out, swirling slightly in the air, and slashed towards the Underworld Monk who flew upside down like a broken kite.

Although the speed of Hongxia is extremely fast, with her eyesight, she can still clearly identify the specific appearance of the red light.

It was a very good-looking flying sword, the whole body was red, crystal like fire jade, and it was shining brightly.

And on the sword, it was Ling Lie's condensed whistling sword qi.

The most bizarre thing is that in addition to this layer of sword qi, the extremely gorgeous phoenix finch pattern on the body of the flying sword is shining at this time.

A layer of flowing and dazzling red brilliance flowed out from the phoenix finch pattern, covering the sword body.

The speed of the flying sword is extremely fast, far more than double the speed of sound, and even close to twice the speed of sound.

Under this extreme speed, the brilliance driven by the flying sword is also extremely gorgeous.

But gorgeous is gorgeous, but it is not flashy and unsubstantial.

The red light of the flying sword was like red lightning, but in the blink of an eye, it was in front of the monk of the underworld.

The extremely sharp flying sword struck on the forehead of the Underworld Monk, even though the Underworld Monk's talisman weapon immediately flashed with a spiritual light to protect him, but under this sword, it was a useless struggle.

Burst!

The flying sword, which was nearly twice the speed of sound, sliced the Underworld monk's forehead bone, and blood flowed out.

The layer of blazing red light attached to the flying sword poured out in an instant, covering the entire body of the underworld monk.

In the next moment, the whole body of this underworld monk actually burned with a wave of crimson flames, and his body was melted in an instant, and after a terrible wail, it turned into ashes scattered in the sky.

[Sparrow Song]: This sword is invulnerable, immune to all fire attacks, and comes with fire damage when attacking.

It is comparable to the strong spiritual power and divine sense of the Jindan monk, the dragon sparrow sword of the Dao rank quality, and the flying sword technique that has been cultivated to the full level.

Under the superposition of the three, in terms of flying sword attainments, Lu Qingshan was no longer much different from the early stage sword cultivation of Jindan.

And Lu Qingshan, who killed the Jindan monk with one sword, just withdrew the flying sword lightly.

The crimson dragon sparrow sword fluttered happily around him like an ichthyosaur.

On the data panel, there are small flashes of fireflies.

[Nine Stripes Golden Pill]: Kill the enemy by leaping over the rank (2/3).

……

For a while, Yutai Qingrun didn't care about making an additional attack on the Difu monk holding the trident magic weapon, but instead set his gaze on Lu Qingshan in disbelief.

At this time, she had already determined that the person who made the shot was Lu Qingshan, who was standing behind her.

However, that underworld monk who turned into ashes was a cultivator in the Jindan period!

Even with her sword foreshadowing, the Jindan monk had already been severely injured.

But Lu Qingshan, who was clearly only a foundation building monk, was able to cut the Jindan monk to ashes with a single sword, no matter what, she felt extremely ridiculous.

Also, the sonic flying sword that can only be achieved by Jindan sword cultivation, Lu Qingshan actually mastered it during the foundation building period?!

What surprised her even more was that Lu Qingshan's flying sword speed was far from just breaking through the threshold, and it was even close to twice the speed of sound?

In the realm of flying swords, the first layer is the speed of sound, and the limit is that the speed of the flying sword breaks through the speed of sound.

The second level of the Flying Sword realm is called Sword Burst Thunder Sound, and the limit of this realm is twenty times the speed of sound.

Even with the cultivation of Tantai Qingrun, the speed of her flying sword has only reached eleven times the speed of sound now, far from reaching the realm of sword explosion thunder.

Yutai Qingrun's heart was a little complicated, and he sighed with emotion:

When I first saw it, it was just a small sword cultivator at the second level of qi refining, but now it has grown to such a terrifying realm, how long has it been?

Wait a minute?!

Yutai Qingrun reacted suddenly.

It seems to be ...... It's only been more than half a year?!

......……

And in the valley, Li Zun, who had glimpsed such a scene from afar, suddenly sank in his heart.

According to the current situation, it seems that it has become impossible to save his life from the hands of the Northern Immortal True Venerable?

No, I won't give up easily!

Li Zun shook off the chaotic thoughts and gritted his teeth and stared at the Northern Soul True Venerable.

In the hands of the Northern Immortal True Venerable, several more thunder snakes began to brew.

Turning his head to look at the Wolf Palace Demon King and the Jackal Demon King on the side, they were all terrified, and they didn't have any back-up at all.

These waste demon beasts can't be counted on, and they can only rely on themselves if they want to survive.

Li Zun already understands the current situation.

In fact, he really has one last escape plan, an escape plan with a very high success rate.

It's just that this plan is too costly for him, and if he is really in a desperate situation, he will never want to act like this.

But now, he has no choice.

No matter how precious things are, they are more important than lives!

In the next instant.

"The way of the devil, there is an end of life and there is an infinite destruction, so there is an end of life and destruction, and there is an end to the ......." Li Zun's heart was ruthless, no longer hesitated, muttered a spell in his mouth, and his hands instantly sealed.

Kwak!

In the dark, it seemed that something was shattered at this moment, and the sound of praise sounded, echoing in the valley.

The next moment, above Li Zun's body, a black demonic aura rose into the sky, sweeping into a tornado above his body.

Bang bang bang!

At this moment, the bones of his whole body made a sound like popping beans, and the already huge and hideous body swelled several points again, skyrocketing from one foot five or six to a huge demon nearly three feet tall.

On the body covered with blue runes, blood vessels protruded, like earthworms, crawling all over Li Zun's body.

And the spiritual power running in the meridians in his body actually began to expand inexplicably, and the momentum of his body increased more than ten times in an instant.

However, with such a surge in strength, Li Zun naturally paid a lot of money, and among his five orifices, there was scarlet to black blood flowing out.

Heavenly Demon Broken Baby**, an extremely vicious demon cultivation method, after the person who uses it crushes his own Yuan Infant, his combat power can temporarily increase several times to more than ten times.

However, after using this secret method, the monk Yuan Ying was shattered, and the Dao foundation was completely destroyed, and I am afraid that it will be difficult to advance to the Yuan Infant again in this life.

Therefore, this secret method is generally only used to fight for life when it is certain to die!
