The newly established Great Yan Dynasty demonstrated unparalleled efficiency. From the day Chen Yuan voiced the slogan of marching south to subjugate the demons in the Golden Palace, the entire court sprang into action.

A constant stream of resources began to flow towards Zhennan Pass.

Because this time, the goal was not simply to kill the Demon Emperor and a few Demon Gods, but also to incorporate the Southern Border into the territory.

To enslave the demons and make them submit to the human race.

Therefore, a large amount of resources was essential.

However, troops were not needed for the time being, because the previously established goal was to destroy the demon race. When he was still in seclusion in Dongying, Zhennan Pass already had at least a million troops gathered.

This battle was the first after the founding of the Great Yan Dynasty, so it was naturally impossible to be careless. Chen Yuan, in his capacity as Emperor, issued an imperial decree, summoning Left National Preceptor Moro and Grand Tutor Old Celestial Master to accompany him.

Jiang He, Chu Changfeng, and many other Pillars of the State also gathered, far surpassing the demon race in terms of strength at all levels.

And the news of his personally leading the expedition south to subjugate the demons spread throughout the world, causing a huge shock. Although many people had expected this day, and were even preparing for it.

Because missing this battle meant that the world would fall into peace for the foreseeable future. In other words, this battle was the last opportunity to earn military merit, and there would be basically no more chances after that.

But no one expected that the Great Yan Dynasty would be so swift and decisive, declaring war on the demons only a few days after its founding. It was clear that this was something that had been prepared long in advance.

Many people regretted it, because if this was the case, they obviously would not get any opportunities.

Regardless of the various rumors spreading outside, Chen Yuan had already made preparations and was eager to completely pacify the Southern Border. After that, there would be a long period of recuperation.

Until... the Immortal Realm descended!

......

On the wall of Zhennan Pass, Zhennan King Chu Changfeng, clad in gilded armor, was discussing matters with Moro and others.

"Senior, when will His Majesty arrive?"

Chu Changfeng asked casually.

Seven days had passed since the Great Yan Dynasty announced the expedition to the world. A large number of resources were being supplied to Zhennan Pass, and Moro, Old Celestial Master, Ling Xu, Tian Xu, Jiang He, and Ancestor Su Ming had all arrived at Zhennan Pass.

But the most crucial person, the Great Yan Sacred Martial Emperor, had not yet made a move, which inevitably led to some speculation.

"His Majesty will come in due time, no need to worry." Moro smiled faintly. Chen Yuan's current strength far surpassed his, and he could not even detect Chen Yuan's whereabouts.

But he felt that he should be arriving soon.

After all, before they set off, Chen Yuan had told them that he would come when everyone was gathered.

"King Zhennan, don't be impatient." Jiang He smiled faintly. Now that the Great Yan Dynasty had been established, although they were informal in private, they basically addressed each other by their official titles in public.

At the same time, their address for Chen Yuan naturally changed to 'His Majesty'.

"Hehe, this king is not anxious, just worried that the demon race will get the news and retreat faster, which will cause a lot of trouble in the future."

Since taking charge of Zhennan Pass, he had been paying attention to the movements of the demon race, constantly thinking about counterattacking and how to wash away the previous humiliation.

Of course, he was not without his own selfish motives.

The other kings were guarding territories that basically had no foreign enemies. Only his Zhennan Pass still had the demon race outside. And he wanted to accumulate some merit for the future.

After all, his foundation was still too weak. Wei Wuque had the legacy of Former Liang King Wei Jinfeng, and the Prince of Pingxi had the merit of the Northern Expedition to the grasslands, as well as a familial relationship with Chen Yuan.

The East Sea King was not only a Sixth Realm immortal, but also had the merit of resisting the Northern Barbarians in a life-and-death battle. Only he, apart from the previous human-demon war, had basically been stationed here all along.

He wanted to earn some merit as his foundation.

"This time, His Majesty is personally leading the expedition. The demon race, which has plagued my Central Plains for thousands of years, will probably never be able to raise its head again." Demon Dao Sacred Ancestor Su Ming said with his hands behind his back.

Looking towards the Southern Border, he sighed.

Judging from Chen Yuan's methods towards the grasslands, the Western Regions, and Dongying, the purpose of this battle was definitely to completely break the spine of the demon race, so that it could never stand up again.

He was much more ruthless than the Chu Taizu of the past.

"For the human race of my Central Plains, it is a good thing." Tian Xu Daoist smiled lightly. After Chen Yuan fulfilled his promise and made the Taixu Immortal Palace the state religion.

He himself had no more obsessions, and was already vaguely close to touching the level of rules.

This time's expedition to the demons was also at his own request, hoping to break this shackle and step into the realm of a half-immortal in this final battle.

"Hehe... yes."

Zhao Danqing also nodded.

Only the Jishi Bodhisattva had a worried look on his face. After the news of Chen Yuan's expedition to the demons reached the Western Regions, he quickly rushed to Zhennan Pass. He did not want to establish any merit.

But he hoped that Chen Yuan would not be too ruthless and leave a way out for the demon race.

After all, no matter how much he had become a monk and a Lingshan Bodhisattva, he was still born from the demon race, hoping to leave some inheritance for the demon race, so that it would not be cut off.

"This..."

Ling Xu Daoist was about to speak when suddenly, everyone present, including him, felt a terrifying aura enveloping them.

In the heavens and earth, the national fortune of Great Yan gathered into a sea, and a young man in a black dragon robe and wearing a sulfur bead crown slowly condensed, stepping down step by step.

Chen Yuan... was here!

"Greetings, Your Majesty."

"Greetings, Your Majesty!"

"Greetings..."

Everyone's faces turned solemn, and they raised their hands to bow to the young man who exuded a huge pressure.

"Rise, everyone." Chen Yuan nodded slightly, then looked at King Zhennan Chu Changfeng and said in a deep voice:

"Beat the drums, gather the troops!"

"Yes, Your Majesty!"

Chu Changfeng bowed and quickly gave the order. Several strongmen immediately began to beat the drums.

"Dong..."

"Dong..."

"Dong..."

Nine consecutive drumbeats sounded, and all the soldiers in Zhennan Pass quickly understood. As if by instinct, they quickly began to leave the city and gather on the huge open space outside the city.

Such a large number, even gathering, took a long time. It took two hours to successfully gather and stand in formation in an orderly manner.

And Chen Yuan, looking at such powerful and elite soldiers, also felt a surge of heroism. No wonder many people always liked to do this kind of thing.

It was indeed refreshing.

When Chen Yuan stepped into the sky step by step, tens of millions of elites shouted in unison:

"Long live His Majesty! Long live His Majesty!"

"For hundreds of years, the demon race in the Southern Border has always been a major problem for my Central Plains human race, regarding my human race people as blood food, and can only establish Zhennan Pass here to resist the demon race.

But now, the situation has changed. I have swept across the Central Plains, pacified the northwest, and now in front of my Great Yan, there is only one opponent left, the demon race. What do you think should be done?"

The thunderous voice resounded accurately in everyone's ears, making them extremely excited.

"Subjugate the demons! Subjugate the demons! Subjugate the demons!"

"That's right, we should subjugate the demons and create eternal peace for my Central Plains human race."

"Serve His Majesty to the death, serve Great Yan to the death!"

"Serve His Majesty to the death, serve Great Yan to the death!"

"Serve His Majesty to the death, serve Great Yan to the death!"

"Send troops, march south!"

Chen Yuan waved his hand, and under the transmission of the drumbeats, the rear team turned into the front team and began to quickly surge towards the Southern Border, accompanied by many farmers clearing the way.

After all, the Southern Border is mountainous and has almost no roads.

Fortunately, the demon race had gathered several times before and had already created large areas of flat land, otherwise, they would really only be able to implement decapitation tactics and would not be able to completely destroy the demon race.

......

Tens of thousands of civilians, coupled with martial arts experts splitting mountains and opening paths for the army in front, were generally quite stable. Although the speed was not fast, Chen Yuan did not intend to pursue speed excessively.

This battle was to break the spine of the entire demon race, not just a few demon gods.

They could just push through.

Of course, such a smooth speed was also inseparable from Chu Changfeng's previous preparations, such as planning the route in advance and constantly opening up mountains along the way.

Among them, the most important role was the giant turtle from Biyou Palace, whose huge size also gave him extremely great strength.

In the following months, the Yan army traveled a full ten thousand miles, making many preparations along the way, cutting down mountains, trees, and burning forests. Everything within sight was destroyed.

In this battle, Chen Yuan actually had another very important thing to do, which was to expand the territory for the Central Plains people by tens of thousands of miles and create several more southern and Sichuan states to gradually allow the human race to multiply and thrive.

Without the oppression of war, the speed of population growth was very fast, and if there was not enough territory and resources to support these people, they would be forced to rebel.

Therefore, from now on, he had to make all the preparations.

The Western Regions desert, the Northern Barbarian grasslands, and the East Sea sea area were not suitable for human habitation. Only the vast land of the Southern Border was suitable, provided that those mountains were leveled.

The poisonous miasma was removed, the forests were burned, and a habitable place was artificially created.

......

Southern Border, somewhere.

Chen Yuan in a black dragon robe slowly condensed in the void, a faint smile on the corner of his mouth. He and Moro and others were leading the way to find traces of the demon race.

After all, if they really waited for the slow progress of the army, the demon race would have already run away.

The decapitation was a must. Moro, Old Celestial Master, and Ancestor Su Ming were doing just that, searching for the traces of demon gods and annihilating them in one fell swoop, and then letting the army come up.

This could avoid killing karma and affecting cultivation.

And only a few people like Chu Changfeng and Jiang He were clear about their departure. Ordinary soldiers and warriors probably still thought that their Sacred Martial Emperor was sitting in the central hub.

Compared to Moro and others, Chen Yuan's route was different from theirs, because he had a very important thing to do, which was to find the traces of the Burning Heaven Demon Emperor.

And kill him!

Earlier, he had left some means to faintly sense where his traces remained, which was to prepare for now.

He was not important, but the luck on him was very important to Chen Yuan.

And here was where he felt the strongest.

The Burning Heaven Demon Emperor must be hiding in the secret realm within this void.

Chen Yuan smiled faintly, his mind moved, and a powerful force of rules quickly surged out, sweeping the heavens and the earth. After a moment, a flash of精光 flashed in his eyes:

"Found you!"

.....

Within the boundary, countless fire crows derived and died, turning into flames, endlessly.

This was a world of only flames, it was the Burning Heaven Demon Realm. After the battle in the starry sky, the Burning Heaven Demon Emperor returned to his old nest, preparing to hide for a thousand years.

First, he would recover from his injuries.

He was not planning to fight Chen Yuan again. He was no match at all. If he was in his heyday and gathered the luck of the demon race, he might have a chance of winning. Unfortunately, who told him to be too careless?

He went to find Chen Yuan alone, resulting in serious injuries. With his current strength, even if he gathered the luck of the demon race, he would not be able to restore his full strength.

Killing Chen Yuan was even more nonsense.

Of course, this could not be blamed on him either. Who would have thought that a celestial-level demon emperor would not be able to do anything to a human immortal? Saying it out loud was completely impossible.

But no matter how impossible it was, the fact was still in front of him.

In the faint flames, a figure slowly condensed, with a demonic face and deep eyes. It was the Burning Heaven Demon Emperor. He opened his eyes and frowned.

During the recovery process, for some reason, he actually felt a sense of unease from the bottom of his heart, as if some danger was approaching.

Before, he might not have cared, but only half a year had passed since the previous battle, so he could not help but be nervous.

"Could it be... that Chen Yuan has set his sights on this emperor?"

The Burning Heaven Demon Emperor muttered to himself, his eyes solemn.

After returning to the Burning Heaven Demon Realm, he lost contact with the outside world and only wanted to recover from his injuries.

Therefore, he did not know that Chen Yuan was now leading the human army to the Southern Border, and was even targeting him first.

"He probably can't find this emperor." He still had some confidence in the Burning Heaven Demon Realm, unless Chen Yuan searched every inch of the Southern Border with his divine sense.

Otherwise, it was impossible to find him.

Otherwise, the Demon God Palace would not have been delayed for so long.

But although he thought so, he was still a little uneasy. At his level, 'heart palpitations' were already a very important means of divination.

"Perhaps..."

Before the Burning Heaven Demon Emperor could finish his words, suddenly, the entire secret realm rumbled, as if someone was bombarding it, and his expression changed drastically in an instant.

"Not good!"

However, having already been found by Chen Yuan, he could not react at all. A huge hole was blasted out of the fiery red sky, and a figure slowly condensed.

It was Chen Yuan. He sensed the surrounding aura and smiled softly:

"Burning Heaven, I... found you!"

....

"Impossible, absolutely impossible, how could you possibly find the Burning Heaven Demon Realm!" The Burning Heaven Demon Emperor condensed his figure, his eyes solemn and even containing horror as he stared at Chen Yuan in front of him.

This... how was it possible!

He had hidden the Burning Heaven Demon Realm and it could not be detected.

"I... am omnipotent!"

Looking at the terrified Burning Heaven Demon Emperor, Chen Yuan smiled faintly. Not only had the balance of power shifted with the demon race, but also with this demon emperor who had almost killed him before.

Before, in the starry sky, was the best and last chance for the Burning Heaven Demon Emperor to kill him. Missing that time meant that it was time for him to retaliate.

"I... you have become emperor?"

The Burning Heaven Demon Emperor stared at Chen Yuan, his heart sinking even more.

With the national fortune on him, coupled with his previous combat power, with his current severely injured state, wanting to fight him was not a matter of winning, but even the chance of surviving was not high.

"That's right, after the battle with you in the starry sky, I became emperor not long ago. The first thing I did after becoming emperor was to march south to subjugate the demons and find your traces."

"You... do you really want to be irreconcilable with this emperor? If you retreat now, this emperor can promise that he will not leave the demon realm within a thousand years and will never be your opponent."

The Burning Heaven Demon Emperor said in a deep voice.

"Then how do we settle the previous accounts? I have always believed that if someone offends me, I will exterminate their entire family." Chen Yuan said.

"You..." The Burning Heaven Demon Emperor's expression was uncertain. After a moment of silence, he continued:

"Okay, this emperor is willing to submit to you and be driven by you from now on. Moreover, I can also help you pacify the demon race and help you gather the true human luck.

How about it?"

"Not how, I came here not only to kill you, but also to eliminate the great danger of the demon race. I don't need your submission."

"You want to destroy the demon race?" The Burning Heaven Demon Emperor was stunned and stared at Chen Yuan.

"That's right."

"Hmph, the coexistence of the human and demon races in the world is the principle of yin and yang, which is in line with the supreme principle of heaven. Even the Martial Emperor did not do such a thing.

You... this is against the way of heaven."

The Burning Heaven Demon Emperor said in a deep voice.

"I have my own way, how can you understand it."

Chen Yuan凝声道.

"Do you really think that this emperor has no fighting power after experiencing the previous battle? Burning the remaining origin and being in the demon realm, this emperor's power is beyond your imagination.

Killing this emperor, you... will be seriously injured even if you don't die, why bother? Moreover, the immortal realm is about to descend. If you have this emperor to help you, you may not have a chance of winning in the future."

Unless it was absolutely necessary, the Burning Heaven Demon Emperor was not willing to risk his life. If he was really so strong, he would not have retreated again and again in the face of the immortal realm.

"You don't need to worry about the immortal realm. I know that this secret realm is closely related to you and should have been opened up by you, but I still came. Guess why?"

Chen Yuan said casually.

"You... are so conceited!"

"This is confidence!"

The Burning Heaven Demon Emperor stared at Chen Yuan, took a deep breath, understood that things could not be done, and with a thought, endless fire crows turned into flames and poured into his body, turning into nourishment.

In a short period of time, this was the only way to have the strength to fight Chen Yuan.

"Okay, then this emperor will try your confidence!"

"Do it."

Chen Yuan was indifferent to the Burning Heaven Demon Emperor's actions.

In a short moment, the Burning Heaven Demon Emperor devoured all the fire crows in the demon realm, and the aura around him rose steadily, pressing the void to the point of distortion. Even the surrounding boundaries were gathering towards him.

Fight to the death!
