Lin Yuan discovered that the light green spiritual liquid in the bottle contained an extremely high concentration of spiritual energy.

However, in comparison, it is still somewhat less concentrated than the spiritual energy in his own soul-locking space.

Although the concentration of spiritual energy in this bottle of light green spiritual liquid is not as high as the concentration of spiritual energy in his own spiritual locking space.

But the powerful medicinal properties contained in it are something that Lin Yuan could never produce on his own.

The powerful medicinal properties wafted out from the bottle.

Lin Yuan felt as if the space in front of him was torn and distorted by the medicinal properties of the space energy contained in the bottle.

The medicinal properties of this space energy are probably due to the addition of empty crystal shell powder into the spiritual liquid.

Speaking of the empty crystal shell, it is a well-known existence in the Shining Federation.

The spiritual creature called the Kongjingbei is the reason why Ostrich Logistics can deliver goods to anywhere within three hours.

Ostrich Logistics claims that it has cultivated the spiritual creature Kongjingbei itself.

It can be regarded as the core spiritual object for Ostrich Logistics to survive.

At the same time, Ostrich Logistics has extremely strict control over the empty crystal shells it cultivates and will never allow the empty crystal shells to flow out of Ostrich Logistics.

Lin Yuan also paid attention to Ostrich Logistics Kong Jingbei, but he never had any way to get in.

This bottle of light blue spiritual liquid contains the treasure of Ostrich Logistics, the powder of the empty crystal shell.

Judging from the level of control that Ostrich Logistics has over Kong Jingbei, it is estimated that only a strong person of the level of his master Yue Hou can do it.

Only then can you get the shell of the empty crystal shell from semi-official forces such as Ostrich Logistics.

Then Lin Yuan turned his gaze to the third item in the beeswax box.

This third item is exactly the space-type source item that his master Yuehou mentioned.

There are hundreds of source items announced by the Huiyao Federation, but not a single one of them is a space-type source item.

However, this does not mean that there are no space-based source items.

On the contrary, as soon as space-based source items appear, they will be fought over by major forces.

Space-type source items have always been the rarest of all source items.

At the same time, there are many types of space-based source items, some are good at combat, some are good at defense, and some have special functionality.

Some forces even compared one of the space-type source items with the island whale.

At one point, this particular type of space-based source item was elevated to the level of a strategic-level treasure.

This specific space-source item has been elevated to a strategic-level treasure by major forces.

Because of the existence of this specific space-source item, it is equivalent to obtaining the qualification for space teleportation.

The space-type source item in front of Lin Yuan is exactly this kind of space-type source item that can be used for space teleportation.

It can be said that it is a space-type source item that can be used for space teleportation, although it is not as precious as the island whale.

But if you really want to be picky, its role for a force is not much less than that of the island whale.

If a force can obtain the ability of space teleportation.

This means that we can ignore the obstacles to the development of power caused by distance.

It is conceivable how important these space-based source items are to the development of a force.

This kind of space-source item that can be used for space teleportation is something that Lin Yuan cannot obtain with his current background.

The reason why Lin Yuan was able to exchange with Gao Feng for a strategic treasure like the Floating Island Whale was because the Gao family had spent a huge amount of resources but was unable to hatch the Floating Island Whale.

Such a floating island whale is of no use to the Gao family and will instead consume a lot of the Gao family's resources.

But even in this situation, Lin Yuan still took out three bronze-grade epic-quality spiritual objects for exchange.

Only then did they exchange it for the floating island whale that had been regarded as waste by the Gao family.

Among the bronze-grade epic spiritual objects that Lin Yuan exchanged, one was the Yellow Spring Lily, a rare bronze-grade epic spiritual object.

Only then did he get the pair of useless floating island whales from Gao Feng.

It can be seen how much importance each major force attaches to the control of strategic-level treasures.

Lin Yuan knew that if it weren’t for his teacher Yue Hou, who gave him this space-type source item that could be used for space teleportation.

Then with Lin Yuan's current resources and background, he could even exchange it for a spiritual object of bronze legendary quality.

You will definitely not be able to exchange it for space-based source items that can be used for space teleportation.

There is no wrong version in the 1619 book forum!

After all, no matter how precious a bronze legendary quality spiritual object is, it can only allow a spiritual professional to own a bronze fantasy quality spiritual object.

However, space-based source items that can be used for space teleportation are strategic-level treasures that can benefit a force and enable it to develop rapidly.

Moreover, even if Lin Yuan used many bronze-grade legendary spiritual objects, he could exchange it for it.

How could Lin Yuan allow this bronze-level legendary spiritual object to easily flow into the market? Lin Yuan has been checking this source item using real data.

This source item looks like a transparent glass ball, but if you calm down and observe carefully, you can see it.

It seems like there is something transparent floating inside the transparent glass ball.

The name of this source item is Ethereal Jellyfish.

To make a contract with the Ethereal Jellyfish, an item of this nature, one needs to break the transparent outer shell.

Then, within one minute, feed it with spiritual liquid that is highly mixed with space energy and contains a high concentration of spiritual energy.

If the specific spiritual fluid is not used to feed it for more than one minute, the ethereal jellyfish will die.

When the ethereal jellyfish is fed to the ordinary level one ordinary quality.

Then drip a large amount of the contractor's blood directly into it, allowing the blood to stimulate the ethereal jellyfish.

The ethereal jellyfish was stimulated by the blood and vomited out all three stomach sacs in its body.

At this time, a large amount of the contractor's own blood is injected into the body of the ethereal jellyfish again.

Use blood to help the ethereal jellyfish grow three stomach sacs again.

At this point, the contract with the ethereal jellyfish is considered successful.

Lin Yuan looked at the contract method of the ethereal jellyfish displayed under the real data, and couldn't help but feel that the contract method of this source creature was really strange.

Lin Yuan touched this with his hand, which was still only in this glass-like sphere.

The ethereal jellyfish, whose actual appearance was impossible to discern, muttered softly.

"With this ethereal jellyfish, we can perform space teleportation. Then the White Servant Plan under the Sky City can also be implemented!"

Thinking of this, a gleam of light flashed in Lin Yuan's eyes. From now on, the Sky City will not only collect resources.

We also need to develop military power! 　I will make up for yesterday's second update~Please vote for recommendation~ I will try to finish updating all four chapters before 8 pm tomorrow.
