Chapter 374: The Demon Beast of the Future

At the top of the faculty building at Caihai Academy, there was a massive office. This office was even more luxurious than the principal's office; it was none other than the four-person office of Nangong Nayue. Although this might seem unreasonable, considering Nangong Nayue's secret identity, it was not strange at all for her to possess such an office.

"Lingyun, there is one thing you must answer me properly!" Nangong Nayue sat in her exclusive seat, staring at Lingyun with a serious expression.

"Hmm? What kind of matter could make you, Yuejiang, so serious?" Lingyun raised an eyebrow slightly.

"Don't try to be funny in front of me. From the words of that little girl just now, you should have realized it too: in the era she comes from, the two of us are legendary existences. In other words, we aren't even on Itogami Island at that time!" Nangong Nayue said in a deep voice.

"To me, isn't that a normal thing? I am a traveler of time and space, wandering through different eras. Leaving Itogami Island is not something worth being surprised about!" Lingyun said with a calm expression.

"Leaving... Itogami Island?" Nangong Nayue suddenly gripped the fan in her hand tightly.

Looking at Nangong Nayue's expression, Lingyun suddenly smiled: "Yuejiang, are you reluctant to see me go?"

Nangong Nayue bit her lip and said nothing.

"Also, don't forget, that girl said that you weren't on Itogami Island either!" Lingyun suddenly reminded her.

"You mean..." Nangong Nayue's pupils constricted.

"Perhaps it is just as you imagine!" Lingyun nodded.

"When are you leaving?" Nangong Nayue pondered for a moment before speaking slowly.

"The time hasn't been set yet. After all, in this world, I still have a big problem to solve."

"What big problem?" Nangong Nayue raised an eyebrow.

Anything that Lingyun would call a "big problem" was definitely not a simple matter. After all, neither the previous Black Death Emperor Faction incident, the Artificial Angel incident, nor even the later Sage had been called a problem by Lingyun. Now that Lingyun said Itogami Island would face a big problem, Nangong Nayue could not help but tense her nerves. One had to know that after suffering so many calamities, the current Itogami Island could not withstand any more turmoil.

"As for that, it's not yet clear. I only have a vague intuition about it." Lingyun looked up at the sky. In his perception, the extremely faint, ominous aura on Itogami Island was gradually increasing in intensity.

"Is this the reason why Luo Yexi and Liuli have been running around Itogami Island all this time?" Nangong Nayue asked.

"Regardless, being well-prepared is the best approach," Lingyun said. In front of him, a light screen slowly unfolded; it was the map of Itogami Island, and on this map were countless dots of light.

"Are you trying to turn the entire Itogami Island into a war fortress?" Nangong Nayue's expression changed slightly as she looked at the map.

"A war fortress? Perhaps!" Lingyun waved his hand and put away the light screen. "But more importantly, it should be to ensure that Itogami Island doesn't sink in the future!"

Just as both of them fell silent, a strange screech suddenly echoed from the sky.

"Is this... a fluctuation of time and space?"

Lingyun and Nangong Nayue exchanged a glance, then simultaneously vanished from the office.

Above Itogami Island, a giant black dragon suddenly appeared, emitting violent roars. Below, Xiao Gucheng, Himeragi Yukina, and the girl from the future who looked extremely similar to Himeragi Yukina were confronting it.

In just an instant, Nangong Nayue deployed an Array to strip away space, isolating this battlefield from the surroundings. If they were allowed to fight in this place, there was no telling how many casualties it would cause. However, because of this, Nangong Nayue, bearing the massive consumption, was unable to join the battle.

"Teacher Lingyun, Teacher Nayue?" Seeing Lingyun and Nangong Nayue appear, Xiao Gucheng let out a sigh of relief. He didn't know when it started, but he had developed the thought that as long as the two of them were present, any incident could be handled properly.

"Yo, Xiao Gucheng, relying on others too much is not a good idea!" Seeming to see through Xiao Gucheng's thoughts, Lingyun reminded him indifferently. "You must know, you are the Fourth Progenitor, the future ruler of the Night Empire. This kind of mentality is unacceptable!"

"As for that, Teacher, I'm still a student right now!" Xiao Gucheng retorted. "As a student, relying on a teacher doesn't seem like such a big deal, right?"

"Nothing in the world is absolute. If one day we leave, what will you do?" Lingyun said.

"Teacher, you're leaving?" Xiao Gucheng was startled.

"Now is not the time to discuss such things. That guy is about to attack!" Lingyun did not answer Xiao Gucheng's question but pointed at the black giant dragon in the sky.

"Gucheng-kun, if you release your familiar, you must be careful. This guy's tail can absorb the magic power of familiars, and it itself can use that magic power to resurrect infinitely!" Xiao Lingcai reminded him from the side.

"There's such a troublesome enemy!" Xiao Gucheng couldn't help but grit his teeth. Under such constraints, his strength would be severely limited.

Seemingly because it felt ignored, the black giant dragon let out a roar of anger, and its long tail instantly transformed into a sharp Spear, stabbing toward Xiao Gucheng's direction.

Seeing this, Xiao Lingcai's expression changed drastically, and she lunged toward Xiao Gucheng: "Watch out, Gucheng-kun!"

Xiao Gucheng was pushed to the ground, staring in astonishment as the tail suddenly pierced out from the Void. The tail was approaching Xiao Lingcai at an extremely high speed, and Xiao Lingcai, who had her back to it and had lost her balance, had already lost the chance to dodge it.

With a "bang," the expected scene of blood splattering did not occur. Lingyun had appeared in front of Xiao Lingcai at some point, an ice shield unfolding before him to block the Demon Beast's tail.

"Being inside Yuejiang's Space Domain and daring to play with space power in front of me—you really are overestimating yourself!" Lingyun said indifferently.

"Teacher Lingyun?" Xiao Lingcai looked at Lingyun, who had suddenly appeared behind her, in astonishment.

Having missed its strike, the black giant dragon let out an angry roar, and a mass of blue light suddenly appeared in its mouth, which it sprayed toward Lingyun.

"Wind Blade!"

Lingyun swept his hand casually, and a sharp Wind Blade shot out from his hand, instantly slicing the blue light in two and then carving a massive wound into the dragon's body. The dragon let out a screech, its magic power surging wildly, and the wound healed in an incredibly short time, disappearing without a trace.

"This kind of recovery power is almost on par with a Vampire!" Himeragi Yukina, gripping Sekkarou, frowned slightly.

With a "hum," the Void distorted, and Lingyun's figure suddenly appeared in front of the Demon Beast. Terrifying power condensed on his fists as he slammed them into the Demon Beast before him.

"Void Shock!"

The entire space where the Demon Beast was located twisted instantly under Lingyun's punch. The Demon Beast let out a shrill roar before being completely torn into fragments by the distorted space, turning into magic power and slowly dissipating into the Void.

"So, so amazing! Is this... Teacher Lingyun's strength?"

Xiao Lingcai stared in astonishment at the Demon Beast dissipating in the sky. To eliminate this Demon Beast, she and Xiao Gucheng's other daughter, Xiao Mengcong, had spent a great deal of effort; she had even chased it through time and space to this place. Yet, such a powerful Demon Beast was something that could be dealt with in a single punch by Lingyun.

"Don't be happy too soon. This guy is just a clone. The real body is still hiding somewhere, and we don't know where!" Lingyun reminded them.

"This guy is a clone?" Nangong Nayue, having dispelled the Space Domain, appeared before Lingyun. "A Demon Beast capable of absorbing magic power is definitely a huge threat to Itogami Island. We must find its location as soon as possible; otherwise, Itogami Island will once again face the crisis of sinking."

Lingyun nodded, and then a Space Array unfolded beside him.

"Transfer student, there is one thing I must remind you of!" Lingyun suddenly said to Himeragi Yukina.

"Teacher Lingyun?" Himeragi Yukina looked at Lingyun with some confusion.

"I heard the Sekkarou in your hand wailing. Your strength is increasing too quickly, and it can no longer keep up with your pace. If it cannot be upgraded, one day it will shatter because it cannot withstand your power!" Lingyun said indifferently.

"This... I understand, I will be careful." Himeragi Yukina nodded, looking a bit dazed.

Seeing Himeragi Yukina nod, Lingyun took Nangong Nayue and left.

Upgrading Sekkarou was no easy task. In the original World Line, Himeragi Yukina's brand-new Sekkarou was brought over by Xiao Lingcai from twenty years in the future—a new Sekkarou that Himeragi Yukina had spent twenty years crafting in cooperation with the Lion King Organization. But now, the time for that Sekkarou to appear had not yet arrived, as Himeragi Yukina's current Sekkarou had not yet shattered. And to upgrade a top-tier weapon like Sekkarou, even the Lion King Organization would have to expend immense effort. It just so happened that they had been doing quite a few small things in the shadows because they were too idle lately; giving them something to do was the best approach. At worst, he could just expend some effort to fuse the two Sekkarous together in the end.

Behind them, Xiao Lingcai couldn't help but frown. She had indeed brought back a Sekkarou from twenty years in the future; it was something her mother had entrusted her to bring. But it was truly difficult to take it out now. Thinking of the Sekkarou in her mother's hand—a weapon with power so heaven-defying that even her father sometimes had to give it a wide berth—her intuition told her that there were definitely some things hidden within this that she did not know about.
