Yang Fan took Hu Fei and flew over Wuliu Town.

When he flew to a certain height, he suddenly paused, closed his eyes, and felt everything around him.

Hu Fei also stopped, but jumped like a monkey in the void, without disturbing him.

"Yes, the ancient strange formation has two layers..."

After a long time, Yang Fan smiled and felt very satisfied.

The entire Wuliu Town is protected by a layer of formations that are invisible to the naked eye.

This is the simplified version of the ancient strange formation on the seven-colored castle in the Nine Nether Secret Realm.

It was originally improved and simplified by Deng Shiyao based on the drawings.

Except for the lack of forbidden law, this formation is similar to the arrangement effect of the colorful castle.

In the formation, the concentration of spiritual energy is much better than that of the outside world. After practicing, you will get twice the result with half the effort.

What surprised Yang Fan even more was that the ancient strange formation that enveloped this place had two layers.

It is divided into two layers: inner and outer layers.

The inner layer is a small array that covers the entire Wuliu Town.

And the outer layer should be the formation of the immortal city within a thousand miles of this radius.

The former is just a small town, insignificant.

However, the latter is an immortal city with a radius of thousands of miles. It has such a large space that it can accommodate hundreds of thousands of monks and is more than enough.

Such a large formation layout must consume a lot of materials and manpower.

"Let's take a look around this fairy city first..."

Yang Fan became interested and took Hu Fei to fly within a radius of thousands of miles.

Soon, the two arrived at the edge of the fairy city.

Not far away, there is a towering city wall that is hundreds of feet high, with a magnificent momentum, and all kinds of creatures appear extremely small in front of it.

Not to mention the height of the city wall, just the materials for building the city, they are all primitive ore materials for refining magic weapons in the world of immortal cultivation.

Perhaps, such low-level original materials are not enough to withstand the attacks of high-level cultivators, but their thickness and height are enough to make people sigh.

The city wall is only ten feet thick, and it is also a material for the world of immortal cultivation, which shows its resistance to attack.

From a distance, it looks like a mountain.

When he arrived near the city gate, Yang Fan also saw a moat, which was hundreds of feet wide.

The river water is guided from the clear river.

Here, Yang Fan's spiritual sense captured the Butian King.

"King Yang finally came out of seclusion..."

The Butian King let out a long sigh, with a little surprise on his face, and came over.

"For the past few years, it's thanks to King Mu."

Yang Fan expressed his gratitude and asked, "I don't know what the progress is going on in this fairy city?"

"Eighty percent have been completed, the city has been built and the formation has been well built, but a large amount of materials is still needed to further condense the walls... But these are probably not something that can be done in a few years, and at least several generations of hard work."

The King of Butian analyzed.

"In fifty years, it is already faster than I imagined to be able to build such a solid fairy city."

Yang Fan smiled with satisfaction.

"This is also thanks to King Yang who has obtained so much material, otherwise the process would not have been so fast."

The King of Butian sighed.

After the Blood-Slaying of the Ghost Fantasy Sect and the Demon Yang Sect, Yang Fan basically took out all the materials in the warehouses of these two sects.

Not only that, he also asked Shi Qianhan to get some "cool labor" in the inland sea and transported a large amount of materials from the inland sea.

Afterwards, Yang Fan talked with the King of Butian to the overall situation of Northern Qin.

When talking about the overall situation of the Northern Qin Dynasty, it is definitely impossible to overcome topics such as "Nine Barbarians" and "Black Wind Demon Emperor".

"King Yang was really foresighted at the beginning. When he was competing with the Three Evil Old Demons, he asked me to send people to infiltrate the 'Nine Barbarians'. Such a vision is incredible."

The King of Butian exclaimed.

As early as when the nine barbarian tribes first attacked the Northern Qin Dynasty and mentioned the "Black Wind Demon Emperor", Yang Fan made such a decision.

Hearing the approval of the Butian King, Yang Fan was not happy, looked at the west of Northern Qin and sighed: "It was almost a kind of intuition to do this, because after hearing you tell the story of the 'Black Wind Demon Emperor', I felt that this person was extremely terrible. Maybe one day he would really make his crazy words come true and flatten the entire thirteen Kingdoms of Northern Qin."

"Yes, King Yang's feeling was right at the beginning. The 'Black Wind Demon Emperor' is not enough to describe it as terrible. Whether it is strength, wisdom, or means, they are all the best. Even the three great cultivators of the Northern Qin are no match for him... If this trend continues, within ten years, the Thirteen Kingdoms of the Northern Qin will be flattened by him."

When the King Butian talked about the Black Wind Demon Emperor, he also expressed deep concern.

Finally, he looked at Yang Fan with a slightly anticipated look: "You even killed the Three Old Demons possessed by the Demon God. Now that you have improved your cultivation level, you may be able to kill this person and let the Thirteen Kingdoms of Northern Qin return to peace."

"If the broken sword is still in my hands, it's naturally no problem. Not to mention the Nascent Soul Stage, even in the God Transformation Stage, it may be killed by my sword."

Yang Fan sighed bitterly: "But Wushuang's whereabouts are now slim, and his cultivation level is also vague."

"That's true," the Butian King certainly understood the plot.

When Yang Fan held the broken sword in his hand, he looked so confidently and arrogant.

Holding this sword in hand, Northern Qin is invincible.

That kind of despising all enemies even made him, an outsider, feel excited.

"I seem to have a feeling..." Yang Fan suddenly took a deep breath, his tone solemn and strange: "One day, I will meet him and fight side by side again..."

"Hope I can see this day."

The Butian King looked expectant, and he had no doubt at all that when Yang Fan and Wushuang joined forces next time, they could challenge all unknown and terrible existences.

However, at his height, he did not have the chance to see Yang Fan and the Broken Sword overlap again.

These are later stories, so I won't mention them for now.

Yang Fan’s current purpose is to find the legendary “Tianyihun Water” and resurrect his father to soothe the last trace of guilt and anxiety in his heart.

A thousand years seem to be very long, but the longer it takes, the lower the success rate of resurrection will be.

Yang Fan naturally understood this.

"I originally planned to leave Bei Qin within three years after going into seclusion and go to the 'Far North'." Yang Fan smiled bitterly: "It's just that Bei Qin is a mess, and I have to clean up."

King Butian nodded: "I understand King Yang's situation. Yuyang Kingdom is our hometown. There are too many things that cannot be given up."

Relatives, friends, teachers, disciples... and this land that you are dreaming about.

"Actually... we are not only looking forward to King Yang's departure, but also the three great monks of the Northern Qin Dynasty."

Suddenly, the King Butian's expression became solemn again.

"How do you say this?" Yang Fan was slightly surprised.

"A few years before you left the customs, the three great monks of the Northern Qin Dynasty sent Nascent Soul monks to ask when you would leave the customs, and even offered assistance to King Yang to fight against the barbarians together."

The King of Butian explained.

After listening to it, Yang Fan pondered for a long time, and a cold light suddenly flashed in his eyes.

"What's wrong?"

"I suspect that the barbarian strong men who came to Wuliu Town to cause trouble today may have other purposes..."

Yang Fan thought deeply.

"You mean...even the senior management far away in the Xiyue Desert is paying attention to your retreat, and this is even the instruction of the 'Black Wind Demon Emperor' himself!!"

The King of Butian couldn't help but take a breath of air conditioning.

"What's so strange about this? I sent someone to pay attention to this person when I was fighting against the Sanyou Old Demon. This "Black Wind Demon Emperor" can become the number one person in the Northern Qin Dynasty today and defeat the Thirteen Kingdoms step by step. Wouldn't it be that unknown factor that I was investigated?"

Yang Fan was not surprised at all.

"What should King Yang do?" asked King Butian Zhengran.

Yang Fan's decision will represent the will of the entire Yuyang Kingdom.

"What else can it do? Of course it's a fight!!" Yang Fan's eyes flashed: "Sweep all enemies, only in this way can I leave Bei Qin with confidence."

After hearing his words, the Butian King was moved and inexplicably excited.

Hu Fei next to him couldn't help but feel excited: "Who said it well, beat it hard, and sweep away all enemies."

Sweep all enemies.

This is Yang Fan's attitude.

Domineering, tough, despising everything.

And it is based on strength.
