The Ghost King looked at the severed right arm, and the contempt in his eyes turned into shock that could not be concealed.

At this moment, he didn't even have time to care about the injuries on his body and roared:

"Your spirit controls the sword, and your Qi is as blazing as the sun. You are not a cultivator at the Spiritual Transformation Realm at all!"

After saying this, even though he saw the scene with his own eyes, the Ghost King still felt a sense of disbelief.

The spiritual energy tide has only been recovering for over a year, and the rules of heaven and earth have only just recovered today to the point where they can withstand the arrival of a great monk who has reached the state of spiritual transformation.

If a real person above the level of a god were to descend upon the world, he would inevitably suffer a severe backlash from the rules of heaven and earth. This was the source of his confidence in being able to suppress Shen Yuan in the beginning.

Under the restrictions of the rules of heaven and earth, Shen Yuan, who stepped into the ghost den from outside Beimang Mountain, was at most at the level of Spirit Transformation. The gap between the level of Spirit Transformation and the level of Spirit Refining was almost insurmountable.

You must know that even if he can now exert the strength of the Ghost King of Refining Gods, it is entirely dependent on this ghost den that is constantly eroding Beimang Mountain.

The Lord of Beimang Mountain uses the gradually restored rules of heaven and earth to erode the present world. The ubiquitous ghost energy around is an extension of the power of the Lord of Beimang Mountain. The power from the First Ghost Immortal almost turns the ghost den into a special blessed land.

It is with the support of the Lord of Beimang Mountain that the Ghost King can exert power beyond the limits of the present world in the ghost cave.

In addition, the Ghost King's control over the ghost den can bring tremendous blessings, so Shen Yuan is simply not strong enough to compete with him as the Ghost King who refines the spirit.

However, Shen Yuan destroyed his ghost claws and cut off his arm with just one sword. His method was definitely not something that an ordinary spiritual cultivator could do. It was definitely a method that only a true spiritual cultivator could use.

In this way, Shen Yuan's realm has exceeded the limitations of this world, and there is definitely a big problem!

Shen Yuan held the Huiming Sword in his hand, and the Yuan Qi of heaven and earth continued to gather around him.

Looking at the shocked one-armed ghost king in front of him, Shen Yuan shook his head and said:

“Too weak.”

Compared with the powerful spirit cultivators Shen Yuan had fought before, whether it was the Giant Clam Water God who could draw on the authority of the Jidu Dragon Palace, or the candidate Saint Yu Ke who had a little bit of Qingxu Heaven, they were far stronger than the Ghost King in front of him.

Not to mention the three genuine saints of the Dongtian Holy Land that Shen Yuan met ten thousand years ago.

The one-armed ghost king in front of him could not inspire Shen Yuan much fighting spirit.

Shen Yuan's words made the One-Armed Ghost King stunned for a moment, and the surging anger in his heart immediately made him forget his concerns about Shen Yuan.

"I was just careless for a moment and you took advantage of me. I will make you pay the price!"

As soon as he finished speaking, the One-Armed Ghost King stretched out his hand and picked up the arm that was cut off by Shen Yuan, and then replaced the severed arm.

The Ghost King in the realm of refining the spirit has a powerful self-healing ability. Unless his body is completely destroyed, a minor injury like a broken arm can be easily recovered by simply reconnecting the arm.

However, the next moment, the Ghost King was horrified to find that even though his arm was reattached, the wound on his arm showed no signs of healing, as if the arm was disconnected from his body.

His red eyes were fixed on the broken part of his arm, and he saw that at the place where his arm was cut off by Shen Yuan, a large amount of Yin Qi and soul had begun to dissipate, as if they had experienced the baptism of thousands of years and were disappearing rapidly.

This arm is not just a body to the ghost, it also represents a part of its soul, which means that he will lose this part of his soul forever.

The Ghost King, realizing this, was furious. He opened his mouth wide as he looked at Shen Yuan who was gradually approaching. The ghost fog within a radius of more than ten miles began to gather into his mouth.

His body rapidly expanded in this dark ghost den and turned into a giant ghost king as big as a mountain.

Among the ghosts around him, there seemed to be countless dark and evil spirits lingering, emitting bursts of heart-wrenching and shrill wails.

“Go to hell!”

The huge foot was raised and stepped heavily on Shen Yuan who was like an ant below. All the power of the devil gathered here at this moment. The earth collapsed and the mountains within a radius of dozens of miles trembled.

However, at the moment of this earth-shaking blow, in the lingering ghost fog, a dazzling sword light, combining sword energy with strength and carrying the might of the bright sun, slashed towards the huge ghost king that stood tall.

"Zhu Ming Cheng Ye!"

The gray ghost fog seemed to have encountered a natural enemy under the power of the Sun Sword. It quickly dissipated without any resistance. The Ghost King's huge body even showed signs of collapse under this sword.

“You deserve to die!”

The ghost fog within the ghost den gathered around himself again, quickly stabilizing the trend of the one-armed ghost king's body collapsing. Four arms made of ghost fog began to grow behind him.

One of the arms opened its five fingers, and a huge black axe grew rapidly. The aura fluctuations showed that it was a mid-grade spiritual treasure. As the axe was swung, it met the sword light that carried the true meaning of the sun.

The speed at which the sword light was killing the ghosts stopped at this moment. The Ghost King waved his other ghost hand, and a huge red and black soul-calling banner appeared.

If it were three thousand years ago, there should have been dozens of spirit-transforming ghosts, hundreds of qi-cultivating ghosts, and tens of thousands of qi-transforming evil spirits in the Ghost King's soul-summoning banner, which could pose a threat to the spirit-cultivating ghost.

However, during the three thousand years of spiritual energy depletion, all the ghosts in the soul-summoning banner became the nourishment for his survival to this day, and in the end, only the dozens of new evil spirits that he had captured in the past few days were left.

"All ghosts, listen up! Kill all the creatures in the ghost den!"

As the Ghost King gave the order, ferocious and vicious ghosts rushed into the battlefield from afar. However, most of these ghosts were only at the Qi Transformation Stage, and there were only three ghosts at the Qi Training Stage.

Naturally, these evil spirits could not join in the battle in the Spirit Refining Realm, so the Ghost King’s target was not Shen Yuan, but Gong Buyu, Xue Mingzhi, and Zhang Jiang who were in the woods.

He could easily see through the realms of several people. Among the three, there were only two Qi-cultivating cultivators. Dozens of evil spirits plus the blessing of the ghost den were enough to pose a fatal threat to the three of them.

As long as he could distract Shen Yuan and make him take action, his goal would be achieved.

Shen Yuan didn't care about the Ghost King's little thoughts at all, and he slashed down with the Huiming Sword again with a light touch.

"Xuan Huang!"

The sword light was still as sharp as ever, and without the power of the sun that dispelled the ghost fog, the Ghost King once again met the attack with the giant magic axe, but the next moment the sound of a violent collision resounded throughout the Beimang Mountain.

The sword light seemed to have the weight of a mountain, and the Ghost King's giant axe almost slipped out of his hand under the blow. The Ghost King's huge body was smashed into the ground by the sword, and the mountain collapsed in an instant.

Shen Yuan's expression remained the same, but the momentum of the sword in his hand changed again.

"It's cold at the end of the year!"

The light of a moon illuminated the earth, and the bone-chilling cold spread from the void. Large areas of ghost fog were frozen by the coldness that was enough to freeze time, and turned into ice particles that fell to the ground.

The middle-grade spiritual treasure could no longer withstand the sharp power of the sword from the revived immortal weapon, and the frozen giant axe shattered along with the sword light.

The Ghost King, who was trapped in the earth, was covered in frost. The biting cold seemed to penetrate into his soul and freeze his spirit as well. The huge body of the Ghost King was covered with cracks like an ice sculpture.

In just three short strikes, three completely different powers were displayed. The Ghost King could no longer withstand the powerful sword force and roared angrily:

"Don't you care whether they live or die?"

Shen Yuan laughed out loud: "Why don't you take a look at your evil ghost subordinates?"

The Ghost King looked in the direction of the voice and his red pupils suddenly contracted.

I saw that the mountains and forests were already covered by ice. The three ghosts in the Qi training stage and dozens of evil spirits had turned into crystal ice sculptures. Only Gong Buyu was walking in this world of ice and snow with Bai Xue in his arms.

On the other side, Xue Mingzhi, covered in starlight and holding a magic sword, was fighting with three evil spirits.

These three evil spirits were deliberately left behind by Gong Buyu. Their cultivation at the peak of the Qi Transformation Realm could not pose a fatal threat to Xue Mingzhi, who was at the Qi Training Realm, but they could still put some pressure on Xue Mingzhi to hone his magical powers.

From beginning to end, the evil spirits summoned by the Ghost King did not play any role at all. The Ghost King looked at Shen Yuan with a look of unwillingness and said in a hoarse voice: "Do you really think you can win?"

As soon as he finished speaking, the Ghost King's remaining arm suddenly pierced into his chest. As a large amount of ghost energy dissipated, a dark black token was taken out from his chest.

On the token was a painting of a magnificent, eerie palace.

"Please help me, Master Yin!"

The next moment, heaven and earth were silent.

The entire ghost den began to tremble at this moment, and an inexplicable sense of familiarity emerged in Shen Yuan's heart.

Afterwards, in several cities outside Beimang Mountain, the power of incense shot up into the sky and turned into streams of light that rushed into the ghost cave of Beimang Mountain.

Almost in an instant, a huge amount of incense power fell into the dark token in the ghost den.

The token pierced into the Ghost King's body like a sharp sword, and the Ghost King's huge body began to change.

His ferocious face, which originally retained the outline of a human, began to gradually lengthen, and the two huge curved horns on top of his head flashed a cold light, and the entire head suddenly turned into a bull's head.

The arm on the body that was cut off by Shen Yuan began to grow continuously, and the powerful aura stirred the entire ghost den and expanded rapidly towards the outside world.

Thirty kilometers, forty kilometers, fifty kilometers. In just a few breaths, they reached hundreds of kilometers, which is almost one-third of the entire Beimang Mountain area.

The body that was originally smashed into the ground by Shen Yuan broke free from the restraints of the ground and turned into a towering god with a bull's head and a human body. In his hands was a pair of iron chains and shackles stained with blood that never dried.

Hundreds of meters around him, the ghost den seemed to be dragged into another space. He could vaguely see a road leading to the underworld, on which countless creatures were roaring and ghost kings were wailing.

"One of the ten great underworld commanders in the underworld, Niutou!"

Such obvious features allowed Shen Yuan to immediately recognize the identity of the god possessed by the Ghost King's body.

Although in many myths, the Ox-Head and Horse-Faced Demons seem to be just minor characters that are not worth mentioning, but if you look into it carefully, you will find that many myths involving the underworld seem to be inseparable from the Ox-Head and Horse-Faced Demons, and the Black and White Impermanence.

This precisely represents the importance of Niu Tou as one of the ten underworld generals. He is also one of the bearers of the underworld rules. As long as a ghost enters the underworld's reincarnation, even a ghost fairy cannot escape his clutches. His realm is at least that of an existence that has reached the fairyland.

As far as Shen Yuan knows, there are many customs of worshipping the Ox-Headed Yin Shuai in Luozhou, Taizhou and other places in Daxia, which enjoy the most prosperous incense and fortune in the world.

Possessed by the Bull-Headed Yin General, the Ghost King swept away his previous decadence, and his eyes were filled with viciousness as if he would tear Shen Yuan to pieces at any time.

"Aren't you very strong?"

"Aren't you able to bypass the restrictions of the rules of the present world and exert the strength of the spirit refining realm?"

“But in front of the Bull-Headed Yin Marshal, even if you are the True Lord of Refining Void and have supernatural powers, you cannot resist the soul-stealing attack from the underworld.

This is the rule of the underworld, and no one can violate it."

Shen Yuan knew very well that what the Ghost King said was true.

When possessed by the Bull-Headed Yin Marshal, the Ghost King's cultivation level climbed to the peak of the spirit refining realm, and did not exceed the limit that could be concealed by the ghost den. However, the Bull-Headed Yin Marshal's ability to take lives and retrieve souls far exceeded the peak of the spirit refining realm.

Especially now that the rules of heaven and earth have been restored to a certain extent, the underworld has gradually interfered with the world. Even the True Lord Lianxu cannot resist the Ox-Headed Yin Marshal in the possessed soul state in front of him.

But what disappointed the Ghost King was that there didn't seem to be much fear in Shen Yuan's eyes. Instead, there was a bit of incomprehensible weirdness, which made the Ghost King's pleasure of revenge dissipate a little.

However, this thought only flashed through his mind. The Ghost King knew that killing Shen Yuan in front of him was the most important thing, and everything else was just details.

The Ghost King controlled the human body with an ox head and raised the chain in his hand, ready to hook the soul of the person in front of him.

However, the next moment, the Ghost King's hand suddenly stopped.

For some reason, his hands that were trying to lift the chains began to tremble involuntarily.

"Could it be that because his true body was injured before, he has difficulty controlling the power of the Bull-Headed Yin General?"

The Ghost King mobilized his spiritual power and tried to raise his hands by force, but the next moment an even more powerful force easily suppressed him.

He looked at his hands blankly, and immediately realized that it was the power of the Bull-Headed Yin Shuai that was resisting him.

"Please help me kill the enemy in front of me, Ox-Headed General Yin. After the matter here is settled, I will definitely offer a great sacrifice to the underworld for General Yin!"

It would have been better if the Ghost King didn't speak. As soon as he opened his mouth, he immediately felt an even more powerful force forcibly taking over his entire body.

Although this body is the original body of the Ghost King, that power is actively drawn by him and its essence is far stronger than him. The Ghost King cannot make any counterattack at all.

The Ghost King said in disbelief:

"Bull-Headed Yin Marshal, I am using the Wheel Order to summon you to come. This is the contract signed between me, Beimang Mountain, and His Majesty the Wheel King.

If you violate the contract, even if you are one of the Ten Great Yin Marshals, you will definitely be punished by the Wheel King!"

The Bull-Headed Yin Shuai, who controlled the Ghost King's body, ignored the Ghost King's questioning and just stared at Shen Yuan, who was dressed in white, in front of him.

The Huiming sword in his hand was slowly sheathed, and Shen Yuan's originally calm eyes began to reveal a supreme majesty that had never been there before. Dressed in white, he looked like an emperor ruling the world.

He looked at the Ox-Headed Yin General. Even though the underworld gods in front of him were as tall as mountains, his eyes were still filled with a sense of looking down on him.

His lips opened and closed, and a majestic voice slowly emerged from his mouth.

"Niutou, why don't you kneel before me?"

The Ghost King, who was originally worried, immediately showed a sarcastic smile on his face:

"What a smart-aleck fool!

Originally, there was an accident with the rotation order, and I couldn't control the power of Niu Tou Yin Shuai, but the guy in front of me took the initiative to anger Niu Tou Yin Shuai.

As long as the Bull-Headed Yin General makes a move, he will definitely snatch this guy's soul and send him to the eighteenth level of hell!"

However, the next moment, the towering bull-headed ghost god fell to his knees with a bang, and all the ghosts within a hundred miles radius trembled violently following the movement of the bull-headed Yin Shuai.

A deep voice came from the mouth of the Bull-Headed Yin Commander.

"Niutou, meet the emperor!"

The Ten Great Ghost Generals of the underworld enjoy incense and sacrifices from Shintoism, and are also one of the incense gods!
