The Underworld Empire was as silent as before.
In fact, it was even quieter than before.
Many low-level undead were still wandering aimlessly along the two thousand miles of the border with the human countries.
It looked no different from before, and there was no dangerous aura.
But in fact, there were already nearly fifty Saint-level and more than five hundred half-Saint-level powerhouses on this less than two thousand miles of border.
It was a truly inescapable net. As long as Yang Dingtian barged in, these terrifying Undead Overlords and Undead Kings would fly over in a frenzy.
And the five experts of Evil ways, led by the Queen Devil Queen, were already lying in ambush outside the Underworld Empire's boundary.
Even if they saw Yang Dingtian enter, they would not make a move.
Outside the boundary, the Evil ways had set up countless Ghost Birds. No matter where Yang Dingtian entered, he would be detected immediately. Then, the five experts of Evil ways would charge at full speed towards this location, trying to surround and capture Yang Dingtian as soon as possible.
Therefore, as long as Yang Dingtian dared to come, he would definitely be captured.
If he could escape from the encirclement of dozens of Saint-level powerhouses and hundreds of half-Saint-level powerhouses, then Yang Dingtian would not be human, but a god.
If this was a large net, then the Ghost Emperor Wentian would be the spider king in the net.
Everyone held their breaths quietly, waiting for the arrival of the prey.
Two hours passed.
Four hours passed.
Six hours passed.
Suddenly …
The Ghost Birds that densely covered the two thousand miles of the border suddenly became restless at a place seven hundred and twenty-five miles away.
Then, a ray of light rushed into the Underworld Empire like a bolt of lightning.
"He's here, Yang Dingtian is here!"
Prince Li Ming, who was the closest, immediately rushed towards the place where Yang Dingtian had entered.
Then, the remaining experts of Evil Ways also received the news from the Ghost Birds.
They all rushed towards the entrance of Yang Dingtian.
As for the Queen Devil Queen, even though she was more than three hundred miles away from the invasion site, she was still able to escape.
However, its Soul Sword charged forward at a speed of tens of thousands of meters per second.
…
A streak of light suddenly charged into the Netherworld Barrier.
Then, the energy jade box filled with Hell Magic Crystals was opened.
Then, these Hell Mana Crystals quickly flew towards the soul ring.
This scene was immediately discovered by the wandering undead nearby. Then, it was also discovered by Ghost Emperor Wentian.
The Nether Ghost Emperor didn't even look carefully. He directly controlled the nearest Half-Saint dead soul to launch a suicidal attack.
In an instant, more than a dozen Half-Saint dead souls condensed into a beam of powerful energy and shot out at a speed of tens of thousands of meters per second.
The ten or so Saint-level Undead Lords in the vicinity also turned into streaks of light and rushed over like lightning.
From beginning to end, not even 0.1 seconds had passed.
Dozens of Undead Lords and Undead Monarchs crazily charged at the invaders.
"Whoosh whoosh whoosh whoosh …"
It really didn't even take half a second.
The energy of the three Half-Saint dead souls that were closest to the invaders suddenly flew over and slammed into the invaders.
"Boom boom boom …"
The three Half-Saint Undead Lords directly completed their suicidal attack.
They fiercely slammed their powerful energy into the invaders.
"It's done, it's done …"
Ghost Emperor Wentian was ecstatic.
Yang Dingtian was hit by three Half-Saint dead souls. He was severely injured and couldn't escape.
Then, two more Half-Saint dead souls crazily slammed into the invaders.
The powerful energy caused an incomparably terrifying tremor.
Yang Dingtian was finished. Yang Dingtian was finished.
Ghost Emperor Wentian immediately controlled the vision of one of the undead souls to see how Yang Dingtian was being attacked.
But after a glance, the Nether Ghost Emperor was completely stunned.
How was this Yang Dingtian? This, this was only a Soul Sword!
Yes, it was a Soul Sword. It was Yang Dingtian's Soul Sword that was close to the Emperor grade.
Yang Dingtian was thousands of miles away, controlling the Soul Sword to rush into the Underworld Empire.
The Soul Ring was embedded in the Soul Sword.
The energy jade box was also firmly attached to the Soul Sword.
After entering the Underworld Empire, the mechanism of the energy jade box was opened, and the Hell Magic Crystals inside quickly flew out.
Then, Xuan Qi energy surrounded the Soul Ring, forming a pure energy vortex that swallowed all the Hell Magic Crystals into the Soul Ring.
Ghost Emperor Wentian was completely stunned.
How, how, how did he do it?
It was true that the consciousness could control the Soul Sword, but it could only fly or release Soul Skills.
There was no Soul Sword that could open the box, and no Soul Sword could control the energy essence to enter the Soul Ring.
The Soul Sword's only function was to attack, so it could also command attacks and fly.
How did Yang Dingtian do it?
Ghost Emperor Wentian was really going crazy!
Yes, these things seemed very simple, but in fact, they were impossible to do.
The first problem was that the Soul Sword had no vision and couldn't determine when it had entered the Underworld Barrier.
The second problem was that the released Sword Soul could easily shatter the entire energy jade box and destroy the Hell Magic Crystals.
This was because the Hell Magic Crystals were very unstable and powerful energy. The Naga royalty Sword Soul was too powerful and would definitely destroy them.
The third problem was to create an energy vortex without destroying the Hell Magic Crystals. This was impossible because the Sword Soul was born to attack.
Then, how did Yang Dingtian do it?
It was very simple!
He entered a meditative state with the Demon Fox.
Then, he wrote a Soul Skill inside.
To be precise, it was two Soul Skills.
The first Soul Skill was that once the Soul Sword entered the energy field of the Underworld Empire's barrier, it would immediately release a repulsive force field of about 1.5 kilograms to open the energy jade box.
The second Soul Skill was to create a pure aerodynamic energy vortex without any elemental energy. It was just right to swallow the scattered Hell Magic Crystals.
That was the most difficult thing to do.
This was because even if it was a pure aerodynamic energy vortex, it would also have elemental energy due to the special energy environment of the Underworld Barrier.
Therefore, when the energy of the vortex reached a certain level, it would destroy the Hell Magic Crystals.
But when the energy of the vortex was small, the speed of devouring would slow down.
Therefore, after many experiments, he found the best balance point.
But even so, it would take more than 30 seconds to devour all the Hell Magic Crystals.
However, this kind of method was already enough to make people gasp in amazement.
When Ghost Emperor Wentian saw this scene, he felt a sense of suffocation.
This was because Yang Dingtian was already in a completely different realm of martial arts.
This was already completely in the realm of Gods.
He never would have thought that Yang Dingtian would actually write his own Soul Skill and use the Soul Sword to complete this series of things.
"Boom boom boom boom …"
One after another, the Half-Saint undead crashed into the Soul Sword and carried out a suicidal attack.
But, but what was the use of this?
The Soul Sword's body was not damaged by any energy.
Its Xuan Meridian was the Thousand Miles Xuan Meridian Essence, which could withstand the energy of the entire Yin Yang Mirror.
The energy of a few mere Half-Saint undead dissipated into the Xuan Meridian Essence when they crashed into it. There was not even a slight tremor.
One second, two seconds …
The Hell Magic Crystals continuously entered the Soul Ring.
Ghost Emperor Wentian's heart was bleeding.
He immediately changed his plan and controlled the next Half-Saint undead to fight for these Hell Magic Crystals.
But …
"Whoosh whoosh whoosh whoosh whoosh …"
Suddenly, countless Naga royalty Sword Souls flew out.
Then, countless Soul Sword Shadows began to form an energy barrier outside, completely enveloping the entire Soul Sword and all the Hell Magic Crystals inside. It was completely airtight.
The Half-Saint undead could not break into this energy prison even though they were crazily attacking from outside.
At that time, Yang Dingtian's Naga royalty Sword Soul had formed an energy prison and wrapped Prince Li Ming inside. The Queen Devil Queen and many others launched a series of suicidal attacks, but they were unable to break it.
These mere Half-Saint undead were of no use at all. It was impossible for them to break in.
The Soul Ring continued to devour the Hell Magic Crystals.
Three seconds.
Four seconds.
Finally, the two Saint undead Monarchs arrived.
Ghost Emperor Wentian immediately controlled the two undead Monarchs and crazily attacked the energy barrier formed by the Naga royalty Sword Soul.
But what was the use? They could not break through it at all.
However, at the same time, the energy of the Naga royalty Demon Core was rapidly depleting.
Four seconds, five seconds, six seconds, seven seconds, eight seconds …
The Saint undead frantically attacked the energy barrier of the Naga royalty Sword Soul, but they could not break through it at all. They could not resist the devouring of the Hell Magic Crystals inside.
Ghost Emperor Wentian was really going crazy, going crazy …
Could it be that he was just going to watch the countless Hell Magic Crystals enter the Soul Ring and be refined into energy essence, and then be devoured by Yang Dingtian to become a Saint powerhouse?
No, it absolutely could not be like this.
Even if he had to pay a huge price, he had to stop it!
Immediately, the Ghost Emperor Wentian roared furiously.
"Ah … Ah … Ah …"
Suddenly, Ghost Emperor Wentian became incomparably huge. He stretched into the sky and tore it apart.
In an instant, the Netherworld Barrier in the sky was torn apart.
The energy from outside suddenly poured in.
The fatal light of the two suns also suddenly shot in from the west.
The energy field in this area was severely damaged. It was no longer a pure Netherworld energy field.
In an instant, the Hell Magic Crystals bore the energy aura of the two suns.
"Bang bang bang bang …"
One after another, they quickly turned into ashes.
And the undead here could not bear it.
One by one, they turned into ashes.
Tens of thousands, hundreds of thousands, millions of undead, tens of millions of undead, they turned into ashes in an instant before the sun even shone on them.
Even the Half-Saint level undead were shattered into pieces.
The Saint level undead were also melted layer by layer.
Ghost Emperor Wentian was so ruthless. In order to stop Yang Dingtian, he killed a thousand enemies and lost nine hundred of his own.
One must know that this Netherworld Barrier was a prison, but it was also a protective shield.
Once the crack was torn open, it would be completely destructive to the undead inside.
"Bang bang bang bang …"
The extremely fragile Hell Magic Crystals quickly turned into ashes.
The Netherworld Ghost Emperor in the Soul Ring suddenly felt his heart bleed. It was too late to devour.
He could not bear it anymore. He rushed out of the Soul Ring and frantically devoured the remaining Hell Magic Crystals.
However, the light of the two suns would soon cause fatal damage to it.
Because even if it was surrounded by countless Sword Soul Energy Shields, the energy of the two suns could still enter.
It was like the strongest tempered glass. It could be bulletproof, but it could not stop the light from shining through.
Therefore, it took less than two seconds to devour.
All the Hell Magic Crystals were turned into ashes.
And the Netherworld Ghost Emperor let out a shrill scream, and then quickly drilled into the Soul Ring.
At the same time, the near-Emperor-grade Soul Sword withdrew all the Sword Souls, turned around, and rushed out of the Netherworld Barrier like lightning.
Like a stream of light, it flew out.
At this time, the Queen Devil Queen's Soul Sword had arrived.
It immediately chased after it like lightning.
And the Queen Devil Queen and the others did not know that it was only a Soul Sword that had entered the Underworld Empire. They thought that Yang Dingtian had escaped.
They immediately chased after it frantically.
Then, they saw a ray of light.
The speed of tens of thousands of meters per second was faster than lightning. In the blink of an eye, it disappeared without a trace.
Although Wu Yu's Soul Sword Wand was fast, it was still not faster than Yang Dingtian's Soul Sword.
Therefore, after a moment, they completely lost it.
The Queen Devil Queen did not even see the back of the figure. She had just arrived in a ball of light and disappeared into the sky.
How could Yang Dingtian fly so fast after being injured?
How could it be?
How could it be?
She looked at this scene in disbelief.
At this time, the Ghost Emperor Wentian inside fell into the craziest roar.
Ah … Ah … Ah, Yang Dingtian, I must tear you into pieces, tear you into pieces!
The anger of the Ghost Emperor Wentian made the entire Underworld Empire tremble.
