Zhang Fan began to study the four-dimensional crystal carefully.

He tapped it with his hand, and the crystal seemed to be hard, but it didn't make any sound.

He tried to cut with his knife, but there was not a single mark left on it.

Next, he slashed with his bloody wings and blasted with his Kaishan fist......

All means have been exhausted, and it is impossible to break this four-dimensional crystal.

I don't know how long I've been researching, and I haven't figured out why.

At this time, he found that there seemed to be another point of light thousands of miles away—yes, although with his eyesight, it was impossible to see thousands of miles away, but that point of light gave him the feeling that it was thousands of miles away.

He hesitated for a moment, and immediately flew quickly towards the point of light thousands of miles away.

As a result, he had only been flying for three minutes, and the point of light suddenly and rapidly enlarged in his eyes.

There was no doubt that he had slammed into that point of light again.

"Ahem......"

Zhang Fan was knocked and coughed a few times.

Sure enough, the distance between these four-dimensional worlds is really not measurable with the naked eye.

When you come back to your senses, look closely at this point of light.

Again, this is a huge faceted crystal.

There are still infinite images in it.

Zhang Fan studied for a long time, but he still didn't gain anything.

At this time, he found a third point of light.

In this way, in an unknown amount of time, he found hundreds of points of light.

He knew that in this four-dimensional space, there were probably infinite such points of light.

It's like the universe with infinite planets.

In this four-dimensional space, Zhang Fan completely felt the insignificance of being a human being.

I feel the smallness, loneliness and helplessness of a person in a three-dimensional world who suddenly breaks into a four-dimensional world.

Zhang Fan no longer chased those points of light.

He stopped in front of a point of light, and stopped there quietly.

It's like a kitten chasing the line group to play, and after being tired of playing, it lies motionless in front of the line group.

He couldn't seem to do anything in this space.

He couldn't find an exit back to the three-dimensional world, and he didn't know where to go.

He is like a man forgotten by the universe, forgotten by time.

When a person is in a lonely environment for a long time, it is easy to develop psychological problems.

In order to avoid this situation, Zhang Fan could only sit down and practice the longevity formula every once in a while.

Gradually, he cultivated the longevity formula more and more frequently.

In the end, he was hovering in the air with his knees crossed almost all the time, practicing the immortal formula motionlessly.

In this kind of cultivation, his spirit beads became more and more condensed.

His mind grew stronger.

I don't know how long he's been cultivating, but in short, according to the timing of the nanowatch, he's been cultivating for a full one hundred and thirty-three years.

At this time, the color of his spirit beads had changed, from the original pale white to the current blood red.

He didn't know what that meant, and he continued to cultivate.

According to the time on the nanowatch, he cultivated for another thirty-two years.

For thirty-two years, he remained almost motionless, as if he were a stone sculpture.

He didn't even open his eyes once.

If it weren't for this next incident, he would probably have continued to cultivate like this forever.

In the silence that seemed to be eternal, he suddenly felt a person appear twenty meters in front of him.

He was amazed.

He'd been in the space for an unknown amount of time, and no one else had ever appeared.

How could a human appear at this time?

He opened his eyes and looked at the human twenty meters away.

I saw that it was a seventeen or eighteen-year-old boy.

He looks slightly thin.

But in his eyes, it seems to contain the universe.

He glanced at Zhang Fan, and it was obvious that he saw Zhang Fan.

However, he looked like he hadn't seen anything - or directly ignored Zhang Fan.

Then he took a step forward and entered the faceted crystal in front of him.

Zhang Fan was surprised: this human who had just appeared was able to enter the multi-faceted crystal?

Zhang Fan had tried countless times, tried countless methods, but he couldn't cut a trace of the crystal, this human being was able to enter the multi-faceted crystal?

Now that he had cultivated the Immortal Secret for long enough, his mind was already as firm as a rock.

He knew that what had just happened was not an illusion.

His heart moved, and he quickly stretched out his blood wings and flew towards the multi-faceted crystal.

It looked like he had been flying for forty-three hours at a distance of twenty meters.

Then he stopped in front of the massive faceted crystal and began to study it carefully.

This multi-faceted crystal is no different from the previous multi-faceted crystal, and it is still an infinite image.

He wondered how that guy got into this crystal?

In front of this crystal, he studied it carefully for a long time.

Finally, the nano watch reminded Zhang Fan: "There is him in the image above." ”

Zhang Fan hurriedly came to the upper side, and on this side, he really saw the human being just now.

I saw him appear on an island full of zombies, and he seemed to be collecting something on this island.

This person's control of space has reached the level of supernatural mastery.

When those zombies attacked him, as soon as his right hand was extended, the zombie would disappear in an instant, and when it reappeared, it was already thousands of meters away.

Sometimes a zombie has just come to him, but it will appear behind him without warning.

……

After a few moments, the boy found a strange-looking stone.

And this stone emits a faint cyan glow

The human seemed to nod in satisfaction.

Then, the five fingers of his right hand danced rapidly.

His hand speed is definitely single for tens of thousands of years.

It was so fast that even Zhang Fan couldn't see it clearly.

In just half a second, a hole appeared in his right hand.

This is similar to the black hole in Zhang Fanci's biological space, except that this hole is a faint blue.

The human threw the blue stone into the blue hole, which then vanished.

"It's ...... Sub-biological space?! ”

Zhang Fan closed his eyes and thought about it for a while, and suddenly came to his senses.

Although this guy didn't use energy stones, the method of building a sub-biological space was exactly the same.

It's just that his method of building space is hundreds of times more clever than Zhang Fan's ignorance.

When the cyan stone was put away, the guy just disappeared.

But soon, Zhang Fan found him again in the other side.

This seems to be the Jurassic of the Earth plane, and there are traces of dinosaurs everywhere in the sky, on the earth, and in the sea.

He searched here for a moment, and found another cyan stone.

After taking it into the sub-biological space, he disappeared again.

Then it appeared on another plane.

He kept appearing in those planes, collecting cyan stones, and disappearing in those planes.

Zhang Fan seemed to understand something.

Each world in this crystal is actually a real three-dimensional world.

As long as you can enter this crystal like him, then you will have mastered the method of traveling through time and space and traveling through various planes.

This person can casually build sub-biological space, and can casually travel through various planes, planes, and planes.

It's definitely an awesome existence.
