The winter sunlight filters through the frosted glass from outside, illuminating the wooden desk in the room.

Kane is at the desk, flipping through a thick book, "Self-Detonation: The Choice of Mechanical Art".

To be honest, they had been resting for almost a week.

It's not that they wanted to rest, but the mechanism of the [Eternal Victory Battlefield] is there.

Only after one wave finishes does the next one open.

When Kane and the team returned, the last exploration had just been underway for less than ten days.

According to average estimates, each wave of the [Eternal Victory Battlefield] generally takes about 30 days to complete.

The longest can be a month and a half, as the entire dungeon collapses just at this time.

The shortest is 20 days, though this is rare, there have been only a few occurrences over the years.

Recently, many battlefield guilds and two world-class forces have settled into Furnace Castle.

This led to an increase in teams coming to explore, initially the condition was that the previous wave's exploration had already ended, but the next wave hadn't yet gathered 200 people.

Recently, it has become seamless; one ends and the number for the next is barely enough.

Now it has become, one hasn't finished yet and those waiting almost fill enough for two waves.

This forced the Mist Council to set up a specific store to register these exploration teams for scheduling.

And during this time, many renowned teams and teams with Silver Bottleneck strength have arrived at Furnace Castle.

What are their goals? That hardly needs to be stated.

This led to many explorers directly canceling their registration.

Because the next exploration has become a battle of the strong, these ordinary explorers would only get trampled like ants.

It's expected that on the official opening day, there won't be teams with strength below Silver Peak.

Moreover, teams keep arriving.

This battle has completely turned into a clash between Bottleneck and Peak tiers.

Just the day before yesterday, betting had already begun.

All teams scheduled to participate were listed.

If you claim the Mist Council didn't have a hand in obtaining these registration details, Kane wouldn't believe it.

Just then, a voice came from Kane's Ruby Lapel Pin.

"Kane, are you interested in sparring a bit?"

Upon hearing Kreya's voice, Kane smiled and then closed the book in hand, responding, "Alright, I'm on my way."

Through the back door of the room, Kane arrived at a large open area carved into a cliff.

The top and surroundings of the area were covered with glowing moss, lighting everything like daytime.

Not only Kreya, but also Longbei and Burton were there, though Longbei was sparring with a shadow that Aikron had entrusted him with.

Kane switched his skills in the Skill Grid to those that enhance training effects.

Sparring with Kreya made Kane realize that ever since she completed her inheritance, both her strength and skills completely overpowered Kane in his ordinary state.

Especially Kreya's combat intuition, compared to Kane's Martial Intuition, is at least one level higher.

Her speed in attacking not only avoids Kane's intuition but impacts him directly.

Conversely, Kane's moves in front of Kreya have almost no advantage; she could dodge them with her eyes closed.

These changes occurred after she received her inheritance.

Especially Kreya's strength, nearly doubling compared to before inheriting.

"Bang!"

The second floor of Longbei Family's wall facing the training yard suddenly blew open a large hole, a figure flew out from inside.

Tracing a curved arc, it crashed in the midst of Kane and others.

Everyone surrounded it, seeing Meizike covered in soot, waving off smoke and standing up, looking quite composed.

"Cough, the experiment had a slight mishap."

"What happened? What happened?" Lilu appeared in several flashes before Kane and others, spotting the soot-covered Meizike.

"Dirty go away," she muttered some... spell?

Then pointed the magic wand at Meizike, instantly clearing away the soot, restoring his original look.

Then looked up at the big hole on Longbei Family's second floor: "Oh dear, what a big hole!"

Everyone's eyes returned to Meizike.

Even the usually impassive Meizike showed a hint of embarrassment, scratching his cheek with one hand.

Lilu blinked onto Longbei's shoulder: "Watch Lilu, I'll fix it in a jiffy."

"You better not be lying," Longbei looked disbelief.

Seeing Longbei's doubt, Lilu blinked outside the broken hole and waved her magic staff, causing the stones to return and seamlessly fit together with no visible seams.

Having done all that, Lilu showed off proudly before disappearing in a flash.

"She's been learning from the Magic Book Aiklonen gave her lately," Kreya explained to the others.

Oh, no wonder, a true genius is working hard now?

Suddenly, a sound appeared nearby, a red teleportation gate opened before them.

What's going on today?

An entity resembling a demon but slimmer than most demons emerged from the teleportation gate.

It had a slender tail and a pair of short horns protruding from two holes in its hat.

Although its outfit seemed unusual, akin to some kind of employee uniform, with a teleportation gate emblem in the middle.

Kane initially thought it was an enemy, but seeing the other's calm expressions,

he realized he was out of his depth again.

The demon came before Kreya, bowed slightly as a salute.

Then took out a large package from its space equipment, placing it before Kreya.

"Miss Kreya, your delivery has arrived. If everything is in order, please mark it as received on this form."

Upon checking the package, Kreya signed as received on the form.

"Thank you for choosing Purgatory Dispatch. We hope to serve you again; have a pleasant day." The demon bowed again, then disappeared through a teleportation gate behind it.

Burton explained seeing Kane's puzzled expression.

"This is Purgatory Dispatch, where Purgatory Demons skilled in teleportation gates serve as couriers. They're fast but quite pricey."

After hearing Burton's explanation, Kane nodded.

This world constantly presents new surprises just when you think you've understood it.
