Chapter 543: Long-Distance Dialogue

Compared to the Underdark, the underground world of the Summoning Alliance is obviously more vast and difficult to explore to the end.

Just what Sean has heard recently, there are more than a dozen underground subhuman kingdoms with a population of over 100 million.

And these subhuman kingdoms are all located at the entrance of the underground world adjacent to the Summoning Alliance.

I believe that in the deeper underground space, there are many subhuman kingdoms that are larger than this one.

The rich ecological environment of the underground world is not much inferior to that of the surface.

In addition to the rich variety of subhumans of various systems, there are also magical beasts and a variety of dark creatures living there.

Sean, who has done some in-depth research on the knowledge related to the underground world, knows that the creature that occupies the top of the food chain in the underground of the wizard world is a special individual called the Abyss Dragon.

The other party seems to be a dragon creature that is more powerful than an ordinary dragon and lives at the bottom of the underground of the wizard world.

Similarly, the number of Abyss Dragons is relatively rare and not everyone can tame them.

The Beren Empire has formed a dragon rider corps that is feared by the wizard world, but no force has been heard of that can tame the Abyss Dragon in large quantities.

In the Summoning Alliance, Sean recently learned that some powerful third-level summoners have Abyss Dragons as summoned beasts.

According to rumors, the tower masters of some holy towers in the Summoning Alliance have the ability to summon dragon kings above level 4.

In Sean's opinion, these rumors are very much like the means by which those holy towers promote themselves.

The Azure Source Holy Tower is too lacking in publicity. So far, the only publicity advertisement that can be shown is the poisonous green flame world that was captured not long ago.

Of course, Sean's earlier first place in the regional Holy Tower Academy War was also a point of publicity for the Azure Source Holy Tower.

That will help the Holy Tower attract more outstanding talents and magic families in the recruitment of apprentices.

...

"Let's start the 213th construction of the void summoning channel." Sean pinched his eyebrows tiredly and said to Yuli in front of him.

At this time, Sean was in a magic tower he rented from the Summoning Alliance.

As expected, money makes things easier.

With the large amount of magic coins Sean paid, the nearby Deep Blue Summoning Holy Tower not only rented a magic tower to Sean in the Holy Tower, but also provided Sean with all the summoning books he needed.

The configurations in all aspects were top-notch.

The experimental equipment Sean used in this luxurious magic tower was second only to those he used on the top floor of the Azure Source Holy Tower.

It is said that this magic tower is specially prepared for third-level great magicians.

The cost of Sean's temporary rental of this magic tower was not low.

The lease period was only two years, and the Deep Blue Summoning Holy Tower asked him for a sky-high price of 400 magic coins, not to mention the cost of the magic books he borrowed from the Deep Blue Summoning Holy Tower.

If everything is counted, Sean has spent more than a thousand magic coins in less than two years since he came to the Deep Blue Summoning Holy Tower.

This is indeed not something that ordinary first-level magicians can enjoy. The second-level magician who was responsible for receiving Sean in the Deep Blue Holy Tower suspected that Sean was the illegitimate son of a demigod-level spellcaster.

With strong mental power, Yuli, a constructor from the Nesser civilization, has been able to help Sean complete some experiments within his ability.

The main reason is that Yuli has a strong learning ability. She helped her a lot in Sean's previous body refining experiment.

Yuli used her strong mental power to help Sean maintain the smooth operation of the magic circle on the experimental table. Sean himself regained his mind and carefully observed the gray vortex channel that was forming in front of him.

A bone finger emitting bursts of death power serves as the core hub of Sean's magic circle.

In fact, although Sean's current void summoning channel is complicated, putting aside those appearances and going directly into the inside, it is essentially relying on the two bone fingers left by the bone dragon Sanchez to find a way to build a space-time channel with the undead world.

The large amount of summoning knowledge and space books obtained in the Summoning Alliance have made up for Sean's shortcomings in this regard.

This prompted him to spend a lot of time and energy to conduct summoning experiments here.

After more than two hundred failures, this time, Sean seemed to finally succeed.

The summoning channel, which was originally filled with gray death power, suddenly changed into a dark and oppressive dark color after the energy element resonance reached a certain frequency.

A rhythmic sound of "clicking" suddenly came from the summoning channel.

The first feeling it gave people was very much like the sound of bones colliding.

"Oh, did it succeed?" Sean's originally tired mind was refreshed, and he hurriedly released his mental power and explored deep into the summoning channel.

However, unfortunately, what finally came out of the summoning channel was not the bone dragon Sanchez, but a skeleton soldier with a life level of about one level.

This skeleton soldier should be a subordinate of the bone dragon Sanchez, otherwise he would not react to Sanchez's bone fingers.

When Sanchez left the subspace secret realm, the first-level undead he took away did not have the skeleton soldier in front of him.

There are only two explanations for this situation: one is that after returning to the Undead World, the Bone Dragon Sanchez recruited a group of followers.

Another explanation is that among the 20,000 undead creatures that followed it to the Undead World, there was another one that broke through to the first level.

But no matter which explanation it is, it indicates that the power of the Bone Dragon Sanchez must have expanded greatly in recent years.

This is good news for both Sean and Lina.

The skeleton soldiers that appeared in front of him quickly cooled Sean's excitement.

However, this summoning experiment was also a success.

Because the undead creatures summoned by Sean are at the first-level level, he can now barely call himself an undead summoner.

Just as Sean waved his hand and was about to end the extremely energy-consuming summoning magic circle in front of him, a strange red light suddenly came out from the eye sockets of the skeleton soldiers in front of him.

"Huh" Sean just made a puzzled sound.

The familiar mental power transmission came out from the eye sockets of the skeleton soldiers in front of him.

"Is it Sean?"

"Lina!" Sean's originally tired and slightly disappointed expression was immediately replaced by surprise.

The skeleton soldier in front of him was not Lina, it was just a medium for Lina to place a ray of mind.

Lina's knowledge of the dead spirit system and space science far exceeded Sean.

It was only after arriving at the Summoning Alliance that Sion made up for his knowledge of summoning and space science, and was able to barely communicate with the world of the dead with the help of his bone finger.

Lina has gone further than Sion in this field.

Perhaps Lina had reached Sion's current research progress a few years ago.

In particular, Lina has the Dark Crystal Magic Wand, which makes it easier for her to communicate with the world of the dead than Sion.

Now Sion and Lina cannot meet again in the world of the dead for the time being, but according to the current situation, they seem to be able to use the channel of the world of the dead as a medium for long-distance communication in advance.
