Please stop persecuting your students!

The place where Xia last appeared.

If we continue to move forward in this direction... we will reach the World Tree, or more precisely, the Great Void, an insurmountable chasm.

'Is it really there? Or...'

McPenny's fingertips continued to move across the map, and finally landed on a simple-looking alligator turtle to the east of the World Tree.

"Is this here?"

......

The Liberaritas Islands are one of the few fixed points in the Netherworld. The islands and reefs composed of medium and large arus that look like super-large alien jellyfish are connected in series at both ends of the wall of the sea of ​​clouds and stay there for many years to form an archipelago.

The resources here cannot be said to be abundant. The land seems to be large in area but in fact the farming area is limited. There are only two simple ports across the two seas and the salvage industry developed around the ports. However, after years of development, there is not much left in the sea area. We can only wait for the ocean currents or the activities of the animals in the sea of ​​clouds to bring the ancient creations from other seas to this sea area.

In general, it is an area with very limited development space. It is basically impossible to make a fortune, and you can only rely on self-sufficiency to get enough food and clothing. If you keep a calm mind, it does have a bit of idyllic meaning.

Because this archipelago does not belong to any country in the Netherworld, the people living here are also very complex. Liberaritas does not have a unique race. People living here are all people from various countries who have fled here for various reasons over the past thousand years. Five hundred years ago, the Ira people, Invidia people, Gulla people, Spebia people, Nopon people... basically all the mainstream races in the Netherworld can be found here... and they can intermarry with each other, which is the most amazing thing.

At this moment, the two of them, who had spent a night on the sea of ​​clouds and made a detour away from the territory of Arcadia to come here, were suspended in the air with their heads raised, looking up at the vast wall of sea of ​​clouds. The teacher and the student were dumbfounded and speechless for a long time.

It was an endless pure white wall, truly towering into the clouds. Even though the two of them were suspended a thousand meters in the air, they could only look up at the wall of clouds drooping like a waterfall.

The height is probably more than 5,000 meters, and the length is immeasurable, stretching horizontally to the end of the field of vision, just like the wall or cliff at the end of the world in the legend of the round sky and square earth. But this 'end of the world' only exists between these two seas, forming a giant natural barrier stretching for more than 100 miles. Even super-large Arus such as Gula and Spebia cannot easily cross it. The uncanny craftsmanship of the sea of ​​clouds in the Netherworld can be seen here.

Saki: “?”

No, wait, you call this 'nature's workmanship'?

......

It’s a little different from what I expected, but this is the new cover!

Volume 624 Return to the Netherworld, the Day the World is Saved: Chapter Chapter Nia: Too embarrassed to look at

"Think carefully... that cloud contains real water, right?"

"Where is Yunhai Sea~"

The teacher and the student looked at each other, puzzled.

They all understood why the sea of ​​clouds, which was similar to water in nature, would inexplicably bulge out in such a large area. If you were to say that there was some kind of mountain range from the old world that forcibly raised the sea of ​​clouds, then the entire sea of ​​clouds should have risen together. At the very least, it should have been a bulge similar to a mound of earth. How could it be a wall? This was liquid!

This doesn't seem to be a natural miracle that can be described simply as "magic work of God", right? This is a miracle of physics!

"So..."

After sighing, the two of them cast their gazes downward, at the strange floating islands and reefs connected in pairs by hardened tentacles, which looked like alien jellyfish. They could clearly see that the road was divided into two starting from a certain floating island. One of the winding roads led to the wall of sea of ​​clouds in front, and the other stretched greatly in height, but finally led to the wall of sea of ​​clouds. Two slightly larger jellyfish-shaped Arus, which looked like they were carved from the same mold, were looming in the wall of sea of ​​clouds, and both paths led into their bodies.

The Cloud Sea Tunnel is the only way for humans to pass through this high wall that cuts across the Cloud Sea, except for a few Arus that can dive. After passing through the bodies of these two medium to large Arus, they will enter a transparent tunnel that runs across the entire wall of the Cloud Sea - it is said that this tunnel is formed by the "force fields" of these jellyfish-like social Arus.

As for the purpose...I think it is also influenced by the design at the bottom of its genes to create an environment suitable for the survival of living things, especially humans.

I don't know whether I should say that it's pathetic - anyway, he is not a vested interest of the Blade system, and I think no one will object to him saying some empty words and casually expressing his feelings here.

After simply flipping through the information he remembered in his head and briefly introducing it, Saki lowered his head and asked:

"Which way do you want to go, Nia?"

"emmmm..."

Nia looked left and right, and finally raised her head to look at the wall of sea of ​​clouds. She, who was afraid of heights like Saki, suddenly wanted to commit suicide.

"How about...we fly over it?"

"Are you afraid of heights?"

"If I'm with the teacher, there won't be any problems~"

"...I hope you can be able to do it alone someday."

"What about the teacher?"

“Actually, my legs are shaking right now.”

He has a fear of heights, an old problem. When he was playing games, he accidentally slipped and fell into the sea of ​​clouds and his heart almost stopped. What about coming here in person?

This leg has been soft since it took off... It's only during combat that I can ignore this problem and move freely.

Nia: “…”

My teacher...sometimes loses his temper unexpectedly...is he like an ordinary person?

"I'm just an ordinary person!"

"? Ordinary people flying in the sky? Attacking transport ships, blowing up pyramids, and assassinating the Pope?"

Nia pursed her lips and casually listed a few incidents that she and Saki had been involved in. She looked up at Saki, who was speechless for a moment, with dead fish eyes, as if to say, "How dare you call me an ordinary person?"

Saki didn't respond and silently approached the sea of ​​clouds passage on their left.

There are certain differences between the two routes in Liberaritas. The one they are taking now leads directly to Mixian Village, and there are relatively fewer monsters along the way. The other route leads directly to another port behind the Wall of Cloud Sea, and there are more monsters along the way - after all, it is a lawless area, and naturally there is no special army to clean up these monsters regularly.

But after all, this is the real world, not a game with fixed numbers and mechanisms. Even if it is that "more dangerous" road, let alone Saki and Nia now, even if Rex and Guangyan are sent there alone, they can easily kill them.

To put it another way, any adult Blade Master can kill them alone. Blade Masters have an overwhelming power advantage when facing non-humans of similar size. Otherwise, why would those core Crystal Hunters and Blade Hunters go into the mountains without saying a word?

However, despite the overwhelming power...

“Don’t come over here, ahh ...

The girl held her long braids that were blown by the wind, squinting her eyes. The surging green spiritual mist in front of her was raging like waves, and accompanied by someone's roar, it filled the space inside the jellyfish-shaped Arus, and then collapsed and compressed towards a certain area! Also existing in this space, several Arus parasites that were living here like free-range chickens and covered with chitinous shells disguised as feathers suddenly let out a series of shrill wails, and then...

Amid Saki's even more terrified roars, the spiritual power that was about to turn into liquid suddenly gathered, and the wailing of the leading parasite stopped abruptly. Its body, which was a circle larger than a tiger, was instantly compressed into a ball the size of a football. The spiritual power that surrounded it from all sides quietly released several tiny holes at specific angles, and the shells, bone fragments and high-pressure green blood flow shot out with a scream, piercing through the remaining parasites and the scattered eggs on both sides. The space inside Arus's abdomen, which had been quite acceptable, suddenly became a mess.

As for those parasites that were occasionally cleaned up by passing travelers and blade masters, they were completely wiped out this time.

Nia(?_?): "...Teacher, aren't you only afraid of spiders?"

"Now it seems...it might be an arthropod, a myriapod, or one with compound eyes. We can't handle it!"

Saki was panting heavily, looking like he was almost covered in a face by an unknown bug the size of a human. Nia silently turned her head and looked at the body parts scattered on the ground in front of her.

You can't handle it, but these harmless insects passing by really can't handle it. Although she can understand this fear, isn't your stress reaction a bit too much?

The brief interlude did not stop the two of them. They walked straight through the jellyfish-shaped Arus that had been killed by a wave of map cannons from Saki, and then a whole new world came into view.

The transparent corridor is like a so-called underwater tunnel, with the unique sand of Liberarita underfoot. The transparent corridor extends all the way forward in the body of Arus behind it. Looking up, in the deep sea of ​​clouds, countless cloud creatures are swimming freely in the light of ether stone, like a dream.

"so beautiful..."

Nia murmured softly, and subconsciously reached out to grab Saki, but was pulled by Saki who was walking forward with his head down, and staggered. However, she was not angry. Nia stared at Saki in a daze, and the corner of her mouth twitched slightly.

"No way?"

"Um..."

Saki looked up, somewhat speechless.

"I also have a fear of the deep sea."

Nia raised her hands to cover her face, too embarrassed to look.

Volume 625: Return to the Netherworld, the Day the World is Saved: Chapter Chapter Did you also pick up a Zohar?

The next day, in front of Misen Island...

"So the tragic scenes along the way were caused by you, the teachers?"

"Ashamed to say that."

This is not the teacher's fault, there is no need to feel ashamed - although a group of students wanted to comfort the teacher in this way, but when they turned around and saw the jellyfish floating island dyed red by colorful blood, they all fell silent.

This is an archipelago on the sea of ​​clouds, in other words, an alternative island. As a result, there are a lot of cloud sea creatures that can be completely classified as "insects" from someone's perspective. Some of the more vicious creatures especially like to ambush under the floating island connecting bridge that is only two people wide. When someone approaches, they will move their pairs of thin legs to climb up and scare people.

They were lucky, as they did scare people. Saki shouted so loudly that his tenor voice pierced their ears over and over again. Nia, who had been staying close to Saki the whole time, still had a buzzing head after a whole day. She held Mel and stayed as far away from Saki as possible, refusing to get close.

As for the ending of those sea of ​​clouds creatures, there is no need to elaborate. It was a cruel and bloody scene that added a layer of brutality and blood to the beautiful and shocking impression of the islands that the group of Tenjin Elementary School students had built in their minds after arriving at Liberalitas and joining Saki and the others after a day. So much so that now they couldn't even persuade them against their conscience.

Everyone was speechless, but Saki had something he wanted to ask Lex—

"Land on the mountain top?"

"You call that a mountain top?"

Saki turned his head to look at the endless wall of sea of ​​clouds, his doubts still lingering in his heart.

This is what he discovered yesterday when he was walking in the Cloud Sea Tunnel. He thought that the tunnel inside should be suspended in the air, but it was actually built on a foundation with no visible border. He thought that there was only cloud water in the wall of the sea of ​​clouds, but there was actually a piece of land?

“There are things the teacher doesn’t know…”

Lex first sighed in a low voice, then looked at the ridge formed by white clouds and explained:

"There are actually super-large Arus here in Liberaritas, but it only lives in the sea of ​​clouds... Well, the Liberaritas island group should be read as 'super-large Arus Liberaritas and a group of floating island Arus', isn't that more appropriate?"

"I see."

Saki nodded. This solved his two puzzles. With such a big creature lurking in the sea of ​​clouds, it could also explain the origin of such a large underground space in Lingdong.

After his little doubt was answered, Saki's eyes swept over the faces that had not changed much from when he left, and finally fell on the tiger who looked like he couldn't wait to show off his new toy, and the girl beside him.

The pair of short braids that once had a mechanical feel turned into two 'long braids' that still retained a mechanical texture, and the childish face with some baby fat was replaced by a more mature and delicate oval face. The standard black and white maid group and maid crown covered the original mechanical body, and the figure became taller and more curvy, instead of being as plain as a steel plate.

"Long time no see, teacher~"

Even the voice has become more lively than before, and it feels like there is something called "humanity" in it... and it is no longer venomous.

Saki stroked his chin and looked at the changed Hana with interest. But then he heard Tiger put his ears on his hips and said proudly:

"How is it?! I'm shocked! This is the new look of Hana - Hana JK!"

Kanat and the others beside him twitched their lips upon hearing this, not knowing where to start to complain about this abbreviation that was full of the dregs of modern civilization, while Saki clapped his hands and said perfunctorily:

"This is really an unexpected change! (Great reading)"

Yan: "Teacher, you wouldn't have already..."

"No kidding, I'm serious."

There was a faint light in Saki's eyes, as if he had noticed something. Hua also raised her head, and there was also a faint light in her golden eyes.

Spiritual power!

There was a spiritual reaction in Hua's body! Moreover, the 'soul' that originally looked much thinner than that of an ordinary person was now very solid and obvious.

"Sure enough, the training method in the Book of Shadows is bound to the soul."

Saki stroked his chin, then looked down at Tiger and asked:

"JK is an abbreviation, right? What's the full name?"

"Oh, teacher, don't be scared. The full name of JK is——"

Kanat, Luka and the others began to roll up their sleeves, ready to suppress the furry boy the moment he blurted out the first letter of the word "female high school student", but they heard Tiger say with a mysterious pride:

"Justice Knight, that is, Justice Knight! It's a word Tiger found in the super ancient language!"

"How cool! A mere tiger can actually have such a cool name!"

A group of modern people looked at Sieg who was shouting and screaming, then looked at Saki, and saw that Saki shook his head imperceptibly, so they suppressed their doubts.

They never expected that a common language/English would suddenly pop out from their mouths, and it was called a 'super ancient language'...

Has this world ever had a civilization similar to Astra/Earth?

Saki looked at the two groups of modern people from different worlds but speaking similar languages ​​standing there in deep thought. He looked up at the sky and didn't want to speak.

Perhaps they gradually began to feel that the history of the underworld was very problematic and worth digging deeper into, but in Saki's opinion... Astra's side was more problematic.

During this period, he had more or less communicated with these students on some topics in their world, and the focus in this regard was on this group of students from Astra.

After all, when he sneaked onto the Astra, he heard something like "World War III" with his own ears, and after some inquiries, he did find out some things that were quite concerning.

A strange unified world that does not attach importance to history, has almost no verifiable history, and can only locate a few major historical events through word of mouth from elders.

In this already weird background, the "little history" known by students seems even weirder.

First of all, it is certain that the world they live in is definitely inextricably linked to the Earth. Familiar country names popped out one by one from the mouth of Alies, who is quite interested in history, and among them were some country names that she had never heard of at all.

Although the world map they drew didn't match, the countries did match...but what came next was the most sensational.

The 'Cuban Missile Crisis', which was once judged to have 'almost destroyed humanity' and almost led to a thermonuclear war, but ultimately the trigger was not pulled...started in their history.
