Thor is a gaseous creature, and except for its brain core, its entire body is composed of clouds and mist.

Therefore, it can blend most of its body into the atmosphere.

Then it flies very fast.

This is also the reason why Thor can catch up with high-altitude rapids and get into it for a big meal.

At the same time, because Thor has no flesh and blood, he does not have various conventional senses.

You won't feel tired, tired, etc.

Simply the best tool...Thor.

Lu Jing rides on the partially hardened Thor's back.

Climbing upward happily.

However, Thor could not fly upwards more than a few thousand meters.

The staircase to the sky suddenly disappeared in an instant.

Lu Jing was stunned immediately.

The first reaction was that the Sky City teleported and disappeared together with the Stairway to the Sky.

I quickly took out my compass and took a look.

But according to the accurate positioning of the compass, the City in the Sky is still more than 20,000 meters above.

However, the Sky City is slowly moving to the northeast again.

"Master, it should have something to do with the material."

Gou Meier analyzed.

I visited Mr. Wu before.

He once said that Castle in the Sky is 'truly' invisible.

This kind of invisibility is not similar to the invisibility of modern fighter jets that avoids radar detection.

It is invisibility in the concept of physics.

You can't see it, you can't touch it, you can't feel it.

It's like it doesn't exist.

Lu Jing has little research on physics and is unable to understand and explain this situation.

But from another aspect.

Lu Jing knew what was going on.

Mustard Seed Space is a small world integrated into the real world.

Lu Jing held the compass and promptly corrected Thor's direction.

While thinking about the information about Mustard Seed Space in my mind.

In order to know yourself and the enemy, you can fight without danger.

Ever since I learned that the City in the Sky is probably a mustard space suspended high in the sky.

Lu Jing asked Gou Meier to retrieve information about Mustard Seed Space from the database.

Only then did we learn that the Mustard Seed Space was actually created by our ancient ancestors.

Use a long-extinct extraterrestrial meteorite as the material.

After the great catastrophe of heaven and earth, that is, within the hundreds of millions of years when Blue Star was formed.

Many extraterrestrial meteorites fell onto the surface of the blue star.

Some of these meteorites have very high spatial density.

This leaves a large void inside.

After ancient ancestors discovered this, they began to use this kind of space meteorite.

Artificially built into a secluded residence.

However, this kind of space meteorite is not as hard as diamond.

On the contrary, it is somewhat fragile.

Therefore, many space meteorites were destroyed by natural disasters and military disasters.

Until the prehistoric flood more than 10,000 years ago.

The ancient ancestors collected the remaining space meteorites and built a floating city in the sky.

Because it is suspended tens of thousands of meters in the sky.

The city in the sky has been preserved to this day.

"Master, my authority is too low. There is only so much information that can be found at present."

The somewhat frustrated voice of the dog girl sounded in my consciousness.

Some blame myself for not helping more.

"It's okay, you have already helped me a lot."

Lu Jing comforted in his heart.

strictly speaking.

In fact, Gou Meier is just the executor of the dog care system.

Only after transforming again and again.

Only then can she have greater authority over the dog care system.

Lu Jing now has twenty opportunities to actively refresh the dog care shop.

I've wanted to refresh it for a long time.

But things kept getting delayed.

We can only wait until we enter the sky garden and then find a place to refresh ourselves.

And Lu Jing now has a premonition.

Twenty refreshes can probably buy several levels of Transformation Pills.

After appeasing the dog girl.

Lu Jing continued to use his consciousness to browse the ancient books and information she sent over.

It's all about mustard space.

Lu Jing wants to increase his understanding of the City in the Sky by learning more about the Mustard Seed Space.

So as not to capsize like the three thunder gods.

It would be a shame to be enslaved and imprisoned in front of the whole world.

About the principle of mustard space.

To put it simply, it is to accommodate a large space in a small carrier.

The mustard seed space means that the mustard seed accepts Xumi.

Contain a space as large as Mount Sumeru in mustard seeds.

Mustard seeds are grass seeds.

Very subtle.

Of course, being careless is just an exaggeration.

Ancient buildings built using space meteorites are the carriers of mustard space.

It doesn't look like much on the surface, but actually there's something else going on inside.

For example, an ordinary tiled house.

Maybe there are vast pastures and streams in the room.

This is the wonder of space meteorites.

According to Thor, the city in the sky covers a large area.

I don’t know what its carrier is.

But now it is almost certain that the carrier of Sky City is blocked by the Sky Garden.

Only after entering the sky garden.

Only then do you have a chance to find the entrance to the Sky City.

Lu Jing raised his head and looked up into the sky, but still couldn't see where the hanging garden was.

I can't help but feel a little uneasy.
