Ning Chuan's current strength is enough to be respected in this world, and once he makes a move, no one can stop him. In addition, the eleven hidden royal families in the Northern Regions have exhausted themselves, it is simply an invincible torrent, and wherever it passes, no force can resist it.

Under such a might, the nine hidden royal families of Nanling surrendered one after another and joined the crusade army. Then, Ning Chuan led twenty powerhouses of the Hidden Imperial Family, sweeping through the White Bone City, Sky City and other places, turning the lineup of the crusading army into thirty Hidden Imperial Families.

Together, these forces form the strongest combat power in this world, and there are forty Heavenly Venerable Realm powerhouses alone, and there are even more God Realm powerhouses, countless of them.

And with the addition of all the hidden royal families, Ning Chuan also completed the unification of this world, and his name spread throughout the world and was worshiped by countless living beings.

"Did you hear that? The powerhouse of our world is going to attack the Exotic Demon Race!"

"This is something that has never happened before, enough to shine through the ages!"

"We have been bullied by the demons for endless years, and now, we can finally let out a bad breath!"

"All this is the handiwork of Emperor Ningren, we want to build a temple for him!"

The whole world was boiling, endless creatures cheered, and in a short period of time, temples rose from the ground, among which the statue of Ningchuan was enshrined, and the whole temple was named the Renhuang Temple.

The name of Ningchuan resounded throughout the world.

At this moment, the crusading army is making its final rest, ready to start its journey at any time. The spatial node that entered the Exotic Demon Realm had been found by Ning Chuan with his powerful soul power and had broken the seal on it.

Near the space node, within a radius of thousands of miles, endless powerhouses are entrenched. An army of cultivators is coming and going, stockpiling war supplies.

Farther away, some alien beast powerhouses came together to join the crusade army, and in just a few days, the number of Tianzun Realm powerhouses increased from forty to fifty, and the number of god-level cultivators was even more numerous.

This is an extremely terrifying force that gathers almost all the powerhouses in this world. In the crusade army, Ning Chuan is respected as the emperor of the people, and his status is so high that it can be called supreme.

But for this, Ning Chuan did not swell, nor did he have any ecstasy. Integrating all the powerhouses of this world to attack the Demon Realm is far more cruel and difficult than imagined, and he will not lose himself because of some false fame.

In fact, if it weren't for the fact that Feng Xueyi's soul was trapped in the Heavenly Demon Sea of the Demon Realm, if it weren't for his skyrocketing strength, he would never have made such a move.

"In this battle, I hope to minimize casualties!" Ning Chuan sighed lightly and fell into deep thought.

Not long ago, when integrating the Nanling Hidden Imperial Family, he unexpectedly got the news that the old man Shangguan Huaimeng, the girl who was taken away by the Buddha Kingdom many years ago, is no longer in this world, according to the news of the hidden royal family, Shangguan Huaimeng was taken to a higher level of the world, infinitely far away from here, even if the Tianzun Realm powerhouse is alive, he can't rush there.

This news suddenly made Ning Chuan's heart sink, could he never see that girl again in this life?

What is the name of the world she went to?

Ning Chuan had no way of knowing, and repeatedly asked the hidden royal family, but unfortunately the other party had limited knowledge. During this period, a very strange thing happened, the Buddhist cultivators who were active in this realm seemed to have disappeared overnight, and even the temple where they were located was gone, leaving deep pits in place.

Ning Chuan was also very helpless about such a result, and now that the crusade army was about to embark on the journey, he could not afford to think about it.

Fifteen days later, all the war materials were ready, countless elixirs were refined, endless armor was draped on the body of many strong men, and a powerful crusading army passed through the nodes of time and space to conquer the demon world.

On this day, billions of living beings from this realm come here to see them off, shouting, offering ordinary food prepared by their own hands, and sending blessings, praying for the early triumphant return of these warriors.

Ning Chuan suspended in the void and watched the mighty army of cultivators below enter the gate of time and space, his expression solemn and heavy. Fifty Heavenly Venerable Realm powerhouses stood quietly behind him, with the same solemn expressions.

I don't know when I will return......

This time, I don't know how many people will bury their bones in other places......

"Let's go!" Ning Chuan lowered his head and sighed, when he looked up again, his face was already full of determination, and he had to send an arrow on the string, even if he was crushed to pieces, he would always solve the troubles of the exotic demons, even if he died, he would save the true soul of Fengxueyi.

A moment later, Ning Chuan turned into a streamer of light and swept towards the gate of time and space.

"Congratulations to Emperor Ningren! May Emperor Ningren win a victory as soon as possible and return triumphantly!" Hundreds of millions of living beings spoke in unison, and the sound shook the heavens and the earth, rumbling and ringing.

"Grandpa...... Grandpa, Emperor Ning will definitely come back, right?" A tiger-headed little guy shook the old man's arm, his big eyes shining with adoration.

The old man smiled kindly, stroked the little guy's head, and said in a deep voice: "Yes! He will definitely come back! He is the human emperor of our world, our hope, and he is invincible!"

"When I grow up, I must become a character like Emperor Ningren, guarding this world and guarding all living beings!" The little guy clenched his fists, and a touch of identification and fortitude that did not match his age appeared on his immature little face.

Such a gesture suddenly made countless good-natured laughter all around.

"I want to write a biography for Emperor Ning Ren and praise his heroic deeds!" said a young man from the mortal world, looking at Ning Chuan's figure that ingested the gate of time and space, his face full of admiration and fanaticism.

His proposal was immediately supported by countless people: "It should be so! His brilliant deeds must be passed down and remembered by our future generations!"

Hundreds of millions of ordinary creatures were in a lot of noise, discussing how to convey the greatness of Ning Chuan. It wasn't until the crusading army all entered the Demon Realm and the gate of time and space was completely closed that they gradually dispersed......

At this time, Ning Chuan led a million crusade army and had officially entered the demon world, and an earth-shattering crusade battle had begun.

It was a dimly lit world, with boundless black clouds covering the land, oppressive and dreary. At the foot is the desolate Gobi Desert, where there is no edge in sight, and there are white skeletons everywhere, gloomy and terrifying.

Swish......

From time to time, there was a pitch-black demonic energy dragging its long tail, hanging down from the clouds, circling and flying between heaven and earth, making this world even more eerie and terrifying.

This is the Demon Realm, which seems to be an abandoned and barren world, with thin aura and monstrous demonic energy.

The army of millions of demons appeared here, as if a boulder was too thrown into the lake, and suddenly made the boundless black clouds in the sky boil, it surged violently, like boiling water, accompanied by a terrible howl, like hundreds of millions of unjust souls struggling, making people's scalps tingle.

Ning Chuan stood in front of the million-strong army, his eyes slightly closed, feeling the spiritual power of the demon realm, and his brows couldn't help but furrow slightly. The aura of the Demon Realm is too thin, not even a tenth of what it is in its normal state, which is obviously a very serious problem.

Once the big war breaks out, the spiritual power consumption on the side of the crusading army will inevitably be very intense, which will cause them to have extremely high requirements for the recovery speed of spiritual power, but according to the thinner spiritual power of the demon world, the recovery speed will be at least ten times longer, which is fatal for the crusading army.

On the one hand, the recovery speed is extended tenfold, and on the other side, the overwhelming demonic energy is quickly recovered, this is destined to be an unfair reality, and the crusade army will not last at all, and will even fall into a desperate situation soon.

In the crusade army, many strong people are obviously aware of this problem, although they carry a large number of elixirs to restore spiritual power, but the territory of the demon realm is vast, and if you fight all the way like this, the elixir will always run out one day. At that time, everyone will face the dilemma of slow recovery of spiritual power, like fish on a chopping board, to be slaughtered.

"Garrison! Don't move forward until you have solved the problem of spiritual power!" Ning Chuan was silent for a long time and gave such an order. A million-strong crusade army encamped at the entrance, occupying a radius of tens of miles, entrenched here, waiting for the next order. Now Ning Chuan is a well-deserved human emperor, and no one dares to disobey an order.

But waiting like this is obviously fatal for the morale of the army. Every time one more day is delayed, the morale drops by one point, and in just three days, most of the sharpness of the million-strong army has been worn out, and even some timid cultivators have begun to retreat.

"Ning Chuan, it's not okay to go on like this!" In the commander's camp, the ancestor of the Qilin Imperial Clan had a bitter face, and he was very worried in his heart, he had already found bad signs in the past few days, and many strong people had lost their previous fearless momentum and began to shrink back.

Fear crept in, and then, like a plague, began to spread to an army of millions. If this kind of symptom is allowed to develop, I am afraid that it will not be long before the so-called million-strong army will be disheartened and turned into a plate of scattered sand.

"The horror of the Demon Realm is far beyond our imagination!" Some Ancestor sighed with a solemn expression, "This is just entering the Demon Realm, and it is so difficult to encounter it, alas, ......"

"Yes, this crusade may not be as smooth as imagined!"

For a while, many Heavenly Venerable Realm powerhouses whispered and were worried.

Ning Chuan frowned, he had naturally already sensed that the atmosphere in the army was not right, and only by continuing to move forward could the will of everyone be cohesive. However, the aura of the demon realm in front of him is too thin, and before finding a way to deal with it, he must not rush into it, otherwise he will fall into the abyss of no return.

Thinking of this, Ning Chuan couldn't help but feel a little irritable, he left the commander's camp and walked around the camp. He tried to relax himself, let his mind feel ethereal, and began to think of countermeasures.

"If there is a crystal mine here, the problem will almost be solved......," Ning Chuan muttered, and then he was stunned for a moment, and his eyes suddenly brightened. He didn't expect that this sudden idea would most likely solve the serious problem of the slow recovery of the spiritual power of the crusading army.
