Reborn as the Candle Dragon, I became the strongest academy guardian beast.

Demon City.

Beneath the black robe, the Night Demon King's crimson eyes trembled violently.

Just a moment ago, he clearly sensed that the Frost Troll, the Thorn Vine Demon, and the Poisonous Flame Spider Queen had been killed one after another.

Not only that, but a million-strong undead army also turned to ashes in that loud bang.

"What a bunch of useless trash!" The Night Demon King was furious.

He never imagined that three demon cadres, plus a million-strong army of undead, would be unable to stop a mere few students!

"Why are you suddenly so angry? Did you lose to my brother?"

"Hmph, I knew my brother would win!" Seeing this, Chu Lingxi smiled gently and proudly raised her little face.

"You reckless little brat, you're asking for it!"

The Night Demon King was utterly enraged.

Since his subordinates were all idiots and useless, he had no choice but to deal with the four of them himself.

But before that, he must kill this little girl first.

As for the promise to let Chu Lingxi go if he wins?

Haha, from the very beginning, he never intended to keep his promise.

"Go to hell!"

The Eternal Night Demon King let out a low roar, and a palm formed from black mist, carrying surging demonic energy, slammed down towards Chu Lingxi's head.

"[Spatial Manipulation]"

However, just as his palm was about to touch Chu Lingxi's head, the blood-red demonic cloud that had lingered for a thousand years above the Demon King's City suddenly tore open to both sides without warning.

A colossal black serpent, obscuring the sky, appeared above the Demon King's castle, its jet-black tail slamming down heavily.

Under this devastating blow, the Demon King's castle collapsed with a roar; the walls crumbled and the stone pillars crumbled...

The Night Demon King was violently swept away by the enormous impact, crashing through several thick walls before finally regaining his footing.

He raised his head, and his bloodshot eyes trembled violently.

Beneath the blood-red sky, an eighty-meter-long black snake-like body stretched across the ruins like a mountain range, its golden vertical pupils looking down at him with calm, indifferent eyes, exuding a suffocating sense of oppression.

"The Azure Dragon Academy's...guardian beast!"

The Eternal Night Demon King sensed a calamity-level aura emanating from Su Chen.

Despite being at the same level of Calamity, he felt a chilling pressure emanating from Su Chen.

The instance is locked, so how did this guardian beast get in?

The Night Demon King suppressed his unease, his scarlet eyes fixed on Su Chen, his voice laced with seduction: "You are not human, why protect these weak ants? Why not join forces with me and divide up the resources of Blue Star? I promise you won't be treated unfairly!"

Su Chen narrowed his golden vertical pupils and sneered, "Who do you think you are, daring to talk to me about cooperation?"

Relying on the Eye of the Demon God, Su Chen had already seen everything that happened inside the dungeon, even though he hadn't entered it.

As the final boss of the [Demon King's Castle] dungeon, the Eternal Night Demon King, possessing calamity-level strength, is clearly not an opponent that Lin Fan and his companions can currently handle.

Since that's the case, he'll have no choice but to have an extra meal.

"If you won't listen to reason, you'll have to suffer the consequences!" Upon hearing this, the Night Demon King's smile froze, and his voice instantly turned icy cold.

His black robe suddenly ripped open, and the billowing black mist beneath it, as if breaking free of its cage, swept wildly in all directions.

The Night Demon King revealed his true form!

Calling it "body" is not quite accurate.

To be precise, the Night Demon King has no physical form.

His true form is a mixture of countless negative emotions such as greed, hatred, resentment, and fear.

That is why the word "fear" has never existed in the dictionary of the Eternal Night Demon King.

Because it's simply impossible for anyone to kill him, who has no physical form!

"Since that's the case, then you might as well die with me!"

As the voice faded, a gigantic black claw materialized from the surging black mist, swirling with demonic energy as it viciously lunged at Su Chen.

"Sizzle!"

The giant claws scraped across Su Chen's dark scales, producing a screeching sound, but couldn't even leave a white mark.

Su Chenyi opened the snake's mouth, and a purple lightning ball condensed and shot out instantly, piercing through the body of the Eternal Night Demon King and blasting a huge hole in the surging black mist.

But in less than a second, the scattered black mist gathered again, completely intact.

Su Chen narrowed his snake-like eyes, as if he understood something.

The Night Demon King's laughter grew increasingly smug: "You can't kill me! No matter how many times you attack, the result will be the same!"

"Really? How about this then?"

A hint of a smile flashed in Su Chen's snake eyes as he dissipated the lightning ball in his mouth and murmured softly:

"【Devour】".

In an instant, a powerful suction force suddenly erupted.

A wisp of black mist was torn apart, detached from the Eternal Night Demon King's body, and dragged into Su Chen's mouth.

[Absorbed a portion of the Eternal Night Demon King's body, gaining 1000 evolution points!]

The Night Demon King's voice abruptly stopped.

He was astonished to discover that after being swallowed, the wisp of black mist had completely lost its connection with him!

This black python was actually able to devour his invisible body!

How is that possible?

What kind of bizarre skill is this?!

The Night Demon King suddenly had a bad feeling.

This was the first time in his life that he had ever felt the fear of death!

The Night Demon King suddenly took a step back, hastily trying to escape from the place.

However, it was too late.

A terrifying suction force surged from Su Chen's snake mouth once more, binding his body like invisible chains.

This incorporeal body of evil began to be torn into pieces, turning into wisps of black smoke, which were then swallowed by that abyss-like maw.

"No...no!"

"Spare me, and I'll retreat back to the Demon Realm, promising never to set foot on Earth again! Whatever you want, I'll give you!"

The Night Demon King let out a hysterical wail.

Su Chen did not answer; his golden vertical pupils were like an abyss, unfathomable.

The terrifying suction force mercilessly tore apart the body of the Eternal Night Demon King, swallowing it all into Su Chen's belly.

[Devouring the Calamity-Level Boss - Eternal Night Demon King]

[Congratulations, host, you have gained 10000 evolution points!]

"It tastes a bit bad."

Su Chen let out a burp and silently complained.

He slowly turned the snake's head, and saw several figures arrive at the Demon King's city.

Lin Fan helped Chu Yunfeng up. Although the latter was covered in blood, his injuries had almost healed.

Xu Liyue and Kong Bowen followed closely behind.

"Teacher? What are you doing here?"

They all noticed the torn sky above them and the fragments of a black robe on the ground that still exuded a calamity-level aura.

It seems the teacher has already taken care of the dungeon boss.

Very competitive.

He truly lives up to his reputation as a teacher...

"Lingxi!" Chu Yunfeng staggered to Chu Lingxi and hugged his little sister's small body tightly.

"I'm sorry for making you worry..."

"I'm not afraid!" Chu Lingxi gently shook her head, raised her small face, and revealed a confident smile:

"Because I know that my brother and the guardian beast will come to save me!"
