Coming to the vicinity of the ruin portal at a depth of several hundred meters underground, Shadow sensed that the location of the giant structure that could be activated was still a certain distance away.

It's about a kilometer or so below the portal.

If it weren't for the snail, Syst would not have found a structure like this diagonally beneath the portal.

With an excavator that swims in the dirt, it won't take much time for Sistham to reach the location of the underground structure.

After more than ten hours, Heatham and a few other bugs managed to reach a thousand meters deep underground.

As the magic crystal used by the shadow activated a blue crystal several meters in size, the earth shook violently as if it were an earthquake......

The large blue crystal emitted a faint blue fluorescence, and a blue mask appeared to block the outside world, completely isolating the earth from the building.

Heatham faintly saw the gray tiles on the ground after the dirt had been isolated, as well as the strange lines on some of the stone tiles.

In the midst of the tremors, Systran felt the earth slowly rising, and Heatham gradually realized what the huge structure of the Shadow House was really about.

"Is it a floating island-like building!?"

A hoarse voice came out of Sisttm's mouth, but as soon as his words passed, the giant blue crystal suddenly extinguished as if the energy was unstable, and the blue light shield that protected and isolated several insects also disappeared, and at the same time, the tremor of the earth stopped, and Sistm and several other insects were buried by the falling soil.

Perhaps due to the lack of energy remaining in the floating island, or perhaps for some other reason, the floating structure only rose a few dozen centimeters before stopping, and did not rise from the ground into the sky.

However, the failure to activate the floating island is in line with the direction of Systm's usual low-key development.

If the floating island did fly, Heatham didn't know what to do with the floating island-like structure.

After all, the floating island is too high-profile, and it is easy to cause unnecessary trouble.

A few hours later.

After the excavator dug hard, Heatham and a few other bugs eventually returned to the surface.

Because the soil near the swamp was generally wet and loose, the tremor of the floating island a few hours ago hadn't changed the ground much.

Some of the cracks and irregular bulges in the ground are not noticeable, and in the large swampy areas, no changes can be observed.

By observing the cracks and bulges in the ground around him, Systm learned that the structure rising from the ground was probably a quasi-circular structure with a diameter of about a kilometer.

And this brief "earthquake" did not attract the attention of any abyssal creatures.

Several magical rank creatures from other territories within more than a thousand meters of the surrounding area were still acting as usual in their territories.

A few giant snakes and large toads either patrol the territory or rest without change.

In order to prevent the abyssal creatures from competing for territory and causing possible trouble, after discovering that the magical creatures in the abyss have territorial awareness, Systm did not kill all the nearby magical creatures, but only asked Shadow to observe these surrounding magical creatures from time to time.

However, after hearing the snail's description of Monet's swamp, Heatham felt that it would be okay to clean up the illusions properly.

Of course, all this is premised on the fact that the snail did not deceive him, and the truth of what the snail said will be investigated for a while.

……

Although this floating island-like structure buried deep underground lacks energy and cannot fly, there must be something hidden in the floating island's building, and perhaps some buildings, as well as some other things.

After a quick thought and planning, Systm paused the construction of the underground lair by the excavator and let the excavator dig the floating islands underground.

If this underground floating island has a lot of valuable buildings, Sistemm doesn't mind using this underground floating island as the center and transforming it into his dungeon in the abyss.

……

……

The excavator's excavation of the underground floating islands began as soon as Systm gave the order.

In his spare time cultivating the nest of demon insects, Systm also keeps an eye on the excavator's exploration underground.

After more than ten days of excavation, the excavator did not disappoint Systm, and it found a cloister of buildings buried in gray stone bricks, and also found two strange spherical halls in the cloister.

Unfortunately, there was nothing in the two halls other than gray stone bricks.

In addition to Systm, the one who pays the most attention to underground buildings is Butterfly Ola.

In recent days, in addition to staring at the large crystal several meters high underground, this lazy butterfly is unusual, and will often urge the excavator when it is digging.

The reason for this is not that Ola has any ambitions for himself to take possession of the floating island, but that Ola feels that there must be a treasure trove in this underground structure.

In Ora's words, she felt the call from the treasure.

Dragons are born with an extraordinary passion for treasures, and perhaps Aura has some sense of treasures, and Systm doesn't care about it.

In addition to studying the nest of demon insects from time to time, and occasionally receiving abyssal summons from different planes, Systm waited for the ant people to return from the half-plane, and listened to the flattery of Snail Jace while waiting.

Heatham does like to listen to the snail's flattery, and although most of the snail's words are a bit exaggerated, Heatham sounds very comfortable.

However, Systham did not always carry the snail to flatter him, but by asking some questions that had been asked to the snail before, and comparing it with the video data in the [Tools Menu] to see if the snail was lying.

Even though more than ten days had passed, Heatham still couldn't fully believe the snail.

He would love to kill the snail and solve this instability.

But the lizardman tribe controlled by this snail still has a lot of use value, and if this snail is killed like this, it will undoubtedly lose control over those lizardman tribes.

After these ten days, Syst has come into contact with a lizardman, and confirmed the authenticity of the snail's words from the lizardman's performance, and Snail Jace has indeed used its hallucinatory ability to brainwash a tribe of lizardmen with low intelligence.

In addition to the remaining two magical rank lizardmen, most of the lizardmen in this lizardman tribe also have the bloodline of thunder and lightning and have the ability to generate electricity.

……

After some consideration, Systm finally decided to keep the snail by his side and continue to observe it for a while.

Time passed little by little, and more than ten days passed, and the many ant people of Sistemm were finally able to come to the abyss from the half-plane......
