Yang Fan even saw the prototype of the starry sky fortress.

It was a disk-like thing, with a diameter of about a thousand feet, thick in the middle and thin edges, which was conducive to swimming in the starry sky.

Deng Shiyao said that if necessary, this disc-shaped starry sky fortress can be turned into a steel ball, and its defense is several times stronger.

It is also an extremely long time to refine the starry sky fortress. Yang Fan only occasionally helps to pay attention to it to see what other materials are needed.

"How long will it take to refine this starry sky fortress?"

Yang Fan couldn't help asking.

Master Tianjiang gave a number: "It will take about 80,000 years."

"We have a master of formations, master of weapon refining, controlled by the Immortal Emperor, a lot of manpower and material resources, and the refined starry sky fortress is also a small-scale growth-oriented type, so it only takes 80,000 years."

Master Tianjiang explained.

Eighty thousand years are quite small in the eyes of Tianjiang.

Like an ordinary starry sky fortress, it takes at least hundreds of thousands of years to successfully cultivate it. It is an always extremely large project.

"Okay, eighty thousand years."

Before leaving, Yang Fan glanced at the Blue Ice Immortal Emperor.

Just a casual glance, Lan Ice Immortal Emperor felt a chill.

Eighty thousand years, even for Yang Fan who has been practicing for a long time, it is still relatively long.

Except for occasionally going out to get some materials, Yang Fan spent most of his time practicing.

Once, during the refining process, Master Tianjiang proposed that he needed a material that only exists in the mortal world.

This material is very ordinary, but it is just a harmonizing effect, but it is also very important.

It just so happens that Yang Fan’s Xianhong space does not have this material.

This incident not only stumped Tianjiang and Deng Shiyao, but also stumped Lan Bing Immortal Emperor.

"With my ability, it is not enough to open the two worlds."

The Blue Ice Immortal Emperor just shook his head.

But he also added: "Unless there is a great emperor-level figure taking action."

A great emperor-level figure?

There is one person in Yunxiao Palace, but Yang Fan is not stupid enough to find Emperor Yunxiao.

"This matter is a bit difficult, I'll go to Daluo Fairyland to see it."

After Yang Fan finished his explanation, he disappeared out of thin air.

The next moment.

Swish!!

The realm of the world, the east-shen continent, and the inner sea of ​​Tianqin.

In the deep sea, a man appeared out of thin air on a puppet.

call!!

Yang Fan took a deep breath and murmured to himself: "The breath of the mortal world..."

If the boss of the upper world knows that there is a person who can easily and casually travel through the upper and lower worlds, this incident will definitely shock the seven realms.

After coming to the mortal realm, Yang Fan subconsciously restrained his breath.

Fortunately, all his cultivation and magic power are left in the life core space. Physical cultivation is physical practice.

The reason for doing this is because of a kind of intuition in the dark.

The moment he stepped into the space of the mortal realm, Yang Fan found that the space he was in was so fragile.

He was afraid that he would break the space by accident.

This kind of "breaking" is not a local space crack, but a chain reaction.

When he was in the mortal realm, crushing the vacuum and shattering the void was a myth for Yang Fan.

But at this moment, Yang Fan was in this space and had to be careful, walking on thin ice.

The so-called crushing vacuum was a complete joke to him, like a child playing house.

Carefully and spreading his spiritual thoughts, Yang Fan found someone related to him.

In the Inner Sea of ​​Tianqin, he discovered many powerful people with the Six Tribulations of Immortals or above.

Several of them have reached the terrifying seven-tribulation scattered immortals.

The seven-tribulation scattered immortal is an existence whose cultivation is comparable to that of the middle-level true immortal. In the human world, he is already a supreme powerhouse.

What surprised Yang Fan even more was that one of the seven-tribulation immortals was actually the disciple he had once accepted, Fu Xue.

Swish!!

Using teleportation magic, Yang Fan quickly found Fu Xue.

"Master...Master..."

Fu Xue, who was practicing in the hidden world, looked at the man in front of her with a panic look on her face.

For more than ten thousand years, his face has remained unchanged at all. His entire aura blends with space and is not distinguished from each other.

If she hadn't seen it out of thin air, her senses would not have sensed this person at all.

"Haha, the disciple doesn't need to question it, he is just a teacher."

Yang Fan smiled gently.

"Master didn't ascend to the upper realm, how could he appear here?"

Fu Xue was shocked and intuition told her that the person in front of her was her master.

"Who said that you can't come back if you ascend to the upper realm?"

Yang Fan pursed a playful smile on his lips.

Yang Fan easily did those things that the supreme and the bosses of the upper realm could not do.

All of this is due to Xianhong Space.

The fairy-horse space maps the vast world.

Directly apply the mapping to the ontology.

——This is the magical power that Yang Fan can only achieve when his cultivation level is promoted to the Great Perfection, and his supernatural powers are as close to the Immortal Emperor.

In the past, mapping could only allow clones and other things with spiritual imprints to do.

At this time, because of mastering the life core space, a real small world.

Yang Fan can use this to connect to a reference space standard for the lower realm through the Xianhong mapping, and then pass through the real small world to the mortal realm.

After a long time, Fu Xue calmed down. To her, the master was like an omnipotent god.

"By the way, where did Fu Ping go?" Yang Fan asked.

Fu Ping is Fu Xue's younger brother.

"Brother...he died in the heavenly tribulation."

Fu Xue's eyes were slightly moist.

After a while.

Yang Fan said to Fu Xue: "I have found your brother's life after reincarnation. After thousands of reincarnations, in this life, he is a prince in a mortal kingdom, you don't need to worry about him."

"Is this true?"

A few surprises appeared on Fu Xue's face.

In her thoughts, after failing to overcome the tribulation, her soul was scattered and she would never lose the opportunity to reincarnate.

However, with Fu Xue's level, it is still impossible to touch the soul's heart seal.

The soul heart seal is the deepest and most mysterious existence in the soul, and it is also a particle of the Great Reincarnation System.

Even Yang Fan didn't see it. What power is there in this world that can directly annihilate the soul heart seal.

Even if it is him, he can only bind and imprison the soul's heart seal.

"If you don't believe it, I can take you there. I'm even sure that he can restore his memory from his previous life, but it's very dangerous to do so."

Yang Fan smiled.

Fu Xue nodded quickly, and she quickly said, "I don't know what is the order for Master to come to the lower realm?"

She was smart and naturally understood that the master who stayed in the upper realm would not come down for no reason.

Yang Fan smiled: "I came to the world for my teacher to help you find the same material."

"Materials?" Fu Xue's face was solemn. Can she do the materials that the teacher couldn't find?
