In fact, when the Ghost King was using the rotation order to summon the Ox-Headed Yin Shuai, Shen Yuan had several opportunities to interrupt the summoning, but he chose not to do so.

The most important reason for this is that Shen Yuan has already sensed the power of incense and faith contained in the rotating order, and the first thing the Ghost King brought over was the power of incense and faith.

Shen Yuan possesses the magical power to drive away gods. Even if a god descends to the world, he must endure the suppression of this magical power.

Moreover, if the realm of a god appearing in the world exceeds the limit of the spirit refining realm, he will inevitably be retaliated by heaven and earth even with the protection of ghosts, so Shen Yuan is not worried about the Ghost King's back-up plan at all.

On the contrary, Shen Yuan was very happy to see the Ghost King use his backup plan, and wanted to use it to test what he relied on.

The final result did not disappoint Shen Yuan. This time, he caught a big fish, Niutou Yinshuai, on a whim.

One of the ten great ghost generals in the underworld, a ghost god of the underworld who has survived from tens of thousands of years ago to the present.

Compared with the powerful strength of Niu Tou Yin Shuai, Shen Yuan was more concerned about the truth behind Niu Tou Yin Shuai's appearance in Beimang Mountain.

From a standpoint, the lord of Beimang Mountain has gathered several ghost immortals and countless ghost kings to form his own ghost den to disrupt the balance of the Yang world. He should be a mortal enemy of Niu Tou, one of the ten ghost generals.

But the reality is that a mere ghost king can borrow the power of the Ox-Headed Yin Marshal, which means that the ghost den in Beimang Mountain has been secretly involved with the underworld.

This is not good news for Shen Yuan.

Fortunately, Shen Yuan noticed that the Bull-Headed Yin Marshal who possessed the Ghost King had a look of shock and fear when he saw him for the first time, as if he recognized Shen Yuan's identity.

This reminded Shen Yuan of the ferocious beast from fairyland that he encountered during the trial in Xuanhuang Linglong Tower. That ancient beast had sensed the divine origin of Shen Yuan without him noticing, and mistook him for Emperor Donghua.

Having already had such an experience, Shen Yuan naturally didn't mind borrowing the identity of Emperor Donghua again.

His magical powers do not fear the Bull Head, but the effects of suppression by force and deterrence by identity are completely different.

For example, right now, Shen Yuan looked at the bull head in front of him with a dignified gaze and asked in a cold voice:

"A dignified commander like Yin is actually involved with this evil ghost den.

Could it be that the underworld is now so chaotic that it ignores the ban on "not interfering with the world"? "

There seemed to be the wrath of an almighty will descending between the words, and an infinite amount of pressure was falling on the incense and sacred road.

The faith and worship that lingered around the Bull-Headed Yin Shuai was suppressed at this moment. The body of the deity, which was supported by the power of the incense, suddenly became ethereal, as if it could collapse at any time.

The Ox-Headed Yin Shuai, who was kneeling on the ground, trembled.

If he had some doubts about the identity of the person in front of him before, now Niu Tou Yin Shuai no longer had any doubts in his heart.

The Bull-Headed Yin Commander showed fear on his face, smashed his huge head on the ground, and responded with an uneasy look:

“Your Majesty, please calm down. Niutou has no intention of intervening in the affairs of the Yang world and violating the prohibition. It is really that the things in Beimang Mountain are too complicated. Not only does it involve the world’s number one ghost fairy, but also the Yamas are involved.

Niu Tou is just a mere Yin Marshal and dares not disobey the order of Yan Luo."

Even though the Ghost King's words before had already made Shen Yuan have some guesses in his mind, the answer he got from the Bull-Headed Yin Marshal still made Shen Yuan feel depressed.

If the Ten Yin Marshals are the bearers of the rules of the underworld, then the Ten Yama Kings are far above the Ten Yin Marshals, because they are the real managers of the underworld among all realms.

The so-called underworld, strictly speaking, is just a part of the underworld that was separated and became independent from the Xuanhuang Realm after the Xuanhuang Realm was cut off from the heaven and earth.

The real foundation of the underworld is the city god system created by the incense and faith of the Xuanhuang Realm.

From the land god in the village to the city god of the county, the county city god, the prefecture city god, and finally the capital city god in the imperial capital of the dynasty, they are linked layer by layer into a big network with the incense and fire domains of the city gods as the veins, governing the reincarnation of the souls of living beings after death.

The Ten Underworld Marshals are a vital part of the underworld system, and their status is second only to the City God in the imperial capital of the dynasty.

However, no matter how powerful the Ten Yin Marshals are, they can only influence the underworld within the Xuanhuang Realm, and are far less capable than the Ten Yama Kings who manage the source of the underworld, the Netherworld.

Because the underworld is the source of all the dark worlds in the world, and is also a vital part of the heavenly system.

The Ten Kings of Hell in the underworld are trying to interfere in the affairs of the Xuanhuang Realm, but Niu-Tou Yin Shuai has no right to disobey due to his status and position.

However, at this moment, Shen Yuan's identity in front of Niu-tou Yin Shuai is "Emperor Donghua". Naturally, the supreme emperor who commands all the gods in heaven will not be moved by the mere Ten Kings of Hell.

The expression on his face remained dignified and indifferent, and Shen Yuan said calmly:

"Yamas? Besides the Wheel King, who else is involved?"

Niutou Yinshuai said hurriedly:

"In addition to the King of the Wheel, the King of the Five Senses, the King of Yama, the King of Biancheng, the King of Metropolis, and the King of Equality have all issued decrees. I am only following orders from the King of the Wheel. The other Yin Marshals also have the shadows of other Yamas behind them."

Shen Yuan was shocked. There were six Yamas mentioned by Niu-Tou Yin Shuai. Except for the top three, King Qin Guang, King Chu Jiang, King Song, and King Taishan who ranked eighth, the rest of the Yamas were involved in the matter of the Lord of Beimang Mountain.

Although the Lord of Beimang Mountain is known as the number one ghost immortal in the Xuanhuang Realm, during his peak period he could only rely on his corpse-reincarnation ability to not be restricted by the underworld and suppress the ten great ghost generals.

Even the Lord of Beimang Mountain in his prime was, to put it bluntly, nothing more than a ghost. Under the order of Yama, he could only be sent to the underworld.

Not to mention that after thousands of years of depletion of spiritual energy, even the ghost den is difficult to maintain. How can it be possible to have any connection with the six of the Ten Kings of Hell?

"There must be a big secret in this!"

Shen Yuan narrowed his eyes slightly and said indifferently:

"Do you know what exactly is going on between the Lord of Beimang Mountain and the Ten Kings of Hell?"

The Bull-Headed Yin General suddenly raised his head, and a trace of barely detectable suspicion flashed across his eyes for a moment, but under the pressure of the divine power that almost became tangible, he quickly lowered his head and said:

"As far as I know, the Lord Yama intervened in the affairs of Beimang Mountain in the name of the Ten Halls of Yama formation."

Although the changes of Niu Tou were covert, they did not escape Shen Yuan's eyes. He realized that the previous questioning had already aroused the suspicion of Niu Tou Yin Shuai.

However, Shen Yuan was not worried. At this moment, he was no longer as timid as before when impersonating someone else.

The realm displayed by the Ox-Headed Yin Marshal who possessed the Ghost King was at best the peak of spirit refining. His most proficient power of the underworld, the soul-binding and life-taking power, was an extension of the divine way and could not be used against Shen Yuan at all.

Even if the Bull-Headed Yin Shuai discovered the problem, Shen Yuan could easily kill him and shatter his soul under the suppression of the Divine Way. This was the confidence given by Shen Yuan's own growing strength.

"The Ten Hells of Hell formation built by the Great Zhou Dynasty to seal off the ancient forbidden land?"

"Yes, it is that great formation."

The Bull-Headed Yin Shuai couldn't help but shrink his neck. For some reason, he just felt an inexplicable sense of fatal threat, but fortunately, everything was fleeting, which made him more honest.

"In the era when the Ten Hells of Hell formation was established, the underworld was still connected to the Xuanhuang Realm Human Dynasty. In order to seal off the dead souls of the ancient times and the resentment of the emperor, the Ten Hells of Hell gathered their own power and the national destiny of the Great Zhou Dynasty to establish the Ten Hells of Hell formation.

As the connection between heaven and earth was severed in the Xuanhuang Realm tens of thousands of years ago, even the underworld was in turmoil. The Ten Kings of Hell urgently needed to regain their authority to suppress the turbulent underworld, so they prepared to dismantle the Ten Kings of Hell formation.

According to the Yama Lords, those ancient dead souls have long since disappeared in the past ten thousand years. Even if the Ten Halls of Hell formation is unlocked, it will not bring any harm. On the contrary, unlocking the Ten Halls of Hell formation will help them regain their authority. "

After hearing these words, I realized the meaning of "in name" that Niu Tou Yin Shuai said.

The Ten Kings of Hell manage the underworld, and the ghosts and gods they rule over are more than billions.

How much power can a mere Ten Hells of Hell array have? It is not enough to allow several Hells to violate the ban and intervene in worldly affairs.

What's more, due to the influence of the Xuanhuang Realm's disconnection from heaven and earth, the Xuanhuang Realm has been cut off from all other realms. Although the Underworld has the Yinsi as a medium of communication, it will inevitably cost a huge price to break through the blockade of the Nine Cauldrons and intervene in it.

Just for a formation, such words can only be used to deceive fools.

Shen Yuan stared at the Bull-Headed Yin Commander: "In name? Then what is the actual purpose?"

The Bull-Headed Yin General lowered his head even lower: "In fact, it may involve the authority of the underworld.

However, I am not qualified to know about such things. I just vaguely heard that the underworld has long been disconnected from the upper world, and the unrest in the underworld is related to this. "

Shen Yuan's eyes narrowed, with starlight flowing in them, and his star-numbering ability began to deduce based on the existing information.

However, Shen Yuan did not rely on the power of the stars this time, because this matter involved powerful figures such as the Lord of Beimang Mountain, the Yin Marshal of the Underworld, the Underworld, and the Ten Kings of Hell.

There are too many high-ranking warriors among them, and the second-level star number supernatural power is simply not enough to deduce the information behind these warriors.

Therefore, Shen Yuan simply used the calculation power of the Star Number Divine Ability and combined it with the existing information to deduce a possibility that was closest to the truth.

After a few breaths, a thought arose in Shen Yuan's heart.

“The thing that involves the power of the underworld is very likely in the possession of the Lord of Beimang Mountain!

Only when he holds the power over the underworld, the Lord of Beimang Mountain is qualified to trade with the Ten Kings of Hell. "

As soon as this thought came to mind, Shen Yuan's thoughts instantly became extremely clear.

“Based on Zhang Jiang’s experience in the ancient forbidden land, and the information that the Ghost King hid his identity and walked out of the ancient forbidden land, we can speculate.

The lord of Beimang Mountain must have hidden in the ancient forbidden land during the period of spiritual energy depletion. I don't know what means he used to avoid the curse of the ancient forbidden land and save himself from dying in these ten thousand years.

However, it is easy to enter the ancient forbidden land, but it is extremely difficult to get out.

The Ten Kings of Hell formation blocked the ancient forbidden land. The more powerful the ghosts were, the more severe the suppression they would receive from the formation. The Lord of Beimang Mountain was unable to escape from the ancient forbidden land.

In the last spiritual tide era, the Lord of Beimang Mountain established contact with the underworld. In exchange for things related to the power of the underworld, he asked the Ten Kings of Hell to untie the formation, and thus obtained the token of the Wheel King.

Perhaps it was because of the infighting among the Yamas, or perhaps there were different positions among the Yamas, the Lord of Beimang Mountain did not succeed in escaping in the last spiritual era.

In this spiritual era, the Ten Kings of Hell are becoming more and more eager for the things in the hands of the Lord of Beimang Mountain, which can be seen from the words of the Ox-Headed Yin Shuai.

The Yamas seem to have reached a consensus and want to untie the Ten Halls of Hell formation."

After this deduction, Shen Yuan has made up his mind. Since he has already stood on the opposite side of the Lord of Beimang Mountain, he must eliminate the Lord of Beimang Mountain, the source of the trouble, before the Ten Kings of Hell actually take action.

Once the Lord of Beimang Mountain successfully escapes from the ancient forbidden land, the ghost den will inevitably spread and occupy the entire Beimang Mountain. By that time, no one in the Xuanhuang Realm will be able to check and balance the world's number one ghost immortal.

Having obtained the information he wanted, Shen Yuan's interest in the Bull-Headed Yin Shuai faded a little.

With his eyelids slightly lowered, Shen Yuan said indifferently:

"I already know what happened. I will handle the matter of Beimang Mountain. You can leave now!"

After finishing speaking, Shen Yuan ignored the Bull-Headed Demon who possessed the Ghost King, turned around and walked towards the direction of the ancient forbidden land.

Niu-Tou Yin Shuai looked at Shen Yuan's departing back with hesitation, but finally gritted his teeth and kowtowed heavily to Shen Yuan.

The huge ghost head slammed to the ground with a bang, and the whole mountain was shaking.

"The gods of the underworld want to maintain the balance of the Xuanhuang Realm, but the underworld is in turmoil, and the ghosts and gods are greedy and want to interfere in the affairs of the Xuanhuang Realm.

I beg your majesty to have mercy on me, maintain order in the underworld, and give justice to the gods of the underworld!"

Shen Yuan's steps as he left paused slightly.

The amount of information implied in Niutou Yinshuai's few words is huge.

The dispute between the underworld and the netherworld involves the balance of yin and yang in the entire Xuanhuang world. Shen Yuan doesn't want to get involved in such a major event.

Even though Shen Yuan's current cultivation strength can be said to be invincible in the world, but in front of those ghosts and gods in the underworld, Shen Yuan's strength is nothing. The only thing he can rely on is his magical power to exorcise gods.

However, the suppression of incense gods by the exorcism magic power is not omnipotent, especially since Shen Yuan's exorcism magic power is only at the first level, which further limits Shen Yuan's performance.

Just as he was about to refuse, Shen Yuan suddenly saw countless stars twinkling before his eyes, and the aura of the star-number magic power guided him.

Behind the dispute between the underworld and the netherworld mentioned by the Bull-Headed Yin Marshal, Shen Yuan seemed to see a thick line of cause and effect, which had already connected this matter with him.

The intuition of the Star Numbers Divine Power told Shen Yuan that if he rejected the cause and effect, he would definitely regret it in the future.

Sensing the thick straight line of cause and effect, Shen Yuan tried to trace the source, but he only saw a hazy future scene. However, there was an unknown sense of familiarity lingering in Shen Yuan's heart.

As time went by, Niutou Yinshuai, who was kneeling on the ground and kowtowing continuously, gradually felt depressed.

He knew clearly that the person in front of him would be the only chance for the gods in the underworld, but he had no idea whether he was willing to intervene in this matter.

The Bull-Headed Demon God became more and more desperate, and at this moment, the majestic voice suddenly sounded in the forest.

"I will go to the underworld."
