136: Chapter 136 Instant Kill

No more waiting.

"Xiao Lin." Qi Yun turned around and looked at Chen Xiaolin, who had just woken up and was stretching her muscles.

"Hmm? Qi Bao, what is it?" Chen Xiaolin perked up.

"Stay in the classroom and be responsible for keeping watch. If any teachers attack, notify me through the channel immediately," Qi Yun instructed quickly.

"Understood!" Chen Xiaolin nodded, a flash of excitement in her eyes.

She knew that Qi Yun was about to make a big move.

"Bai Yu, come with me."

"Yes," Bai Yu replied calmly.

The stairwell was empty, with only the sound of their footsteps echoing in the vast space.

Qi Yun counted the floors silently.

Five, six... ten... fifteen...

Along the way, they didn't encounter any obstacles, nor did they see any other figures shrouded in black mist.

Just as they stepped onto the final stair leading to the sixteenth floor—

A tall figure appeared at the corner of the stairs, blocking the entrance to the sixteenth-floor corridor.

"The path ahead is blocked. Please turn back."

Qi Yun stopped and looked at him calmly: "What if I insist on going?"

"Not allowed," the guard replied concisely.

The whistle was not loud, but it carried a special frequency.

He was calling for reinforcements!

The next second, hurried and heavy footsteps echoed from downstairs!

In the blink of an eye, over a dozen figures shrouded in black mist blocked Qi Yun and Bai Yu at the stairwell landing of the sixteenth floor!

The person leading them was none other than the female Dean of Students who had been humiliated by Qi Yun yesterday.

"This ends here, Qi Yun." The female Dean of Students' hoarse voice rang out, carrying an authority that attempted to control the situation.

"Take your people and retreat immediately. If you try to move forward again, it will be a fight to the death!"

The other teachers behind her also stepped forward one by one.

Qi Yun smiled.

"The black mist indeed grants you invincible attributes, but at the same time, it also forbids you from using your abilities, right?"

The female Dean of Students' scarlet pupils constricted sharply!

"If it weren't for this layer of black mist, relying only on your own abilities, I'm afraid you wouldn't even be able to suppress the students downstairs, would you?"

This was the conclusion he had drawn through observation.

These "teachers," aside from relying on the rules of the black mist for physical protection and attacks, had never displayed any other abilities.

The female Dean of Students' expression clearly turned extremely ugly.

"So what? We have sixteen people, and you only have two! As long as we dispel the black mist, we can use our abilities."

"Sixteen against two, the advantage is on my side. When that happens, the two of you will have no choice but to die! Retreat now, and there's still time!"

"Sure. Then let's give it a try."

Qi Yun nodded, his smile growing colder.

"Let's see who dies and who survives."

The female Dean of Students hesitated no longer, and the next instant, the black mist on the teachers dissipated.

At the very moment the black mist dissipated, a series of faint cutting sounds rang out.

Sensing danger, the female Dean of Students instinctively turned her head to dodge the strike.

Meanwhile, the fifteen black-mist "teachers" behind her, who were just moments ago aggressive and preparing to swarm them, were now all frozen in place.

The expressions on their faces were still fierce.

And then, fifteen heads slid off in unison.

"Thump, thump, thump, thump..." The heads hit the stair steps, making dull thudding sounds as they rolled.

Instant kill. A true, suspense-free, crushing instant kill.

The female Dean of Students stood frozen on the spot, her mind blank.

She hadn't even seen how Qi Yun attacked; in the blink of an eye, the fifteen teachers under her were all decapitated?

"Sole... Unique Class...?!!" She looked up abruptly, her eyes fixed on the man with the calm expression on the platform above.

"You are a Sole-Class professional...?!!"

She finally understood! Why this Qi Yun was so confident!

Qi Yun looked down at her, his eyes cold.

"You know too late."

Before the words faded, Qi Yun's figure vanished again!

The female Dean of Students panicked, her survival instinct driving her to desperately retreat, attempting to defend or dodge!

However— "Ssh!" A soft sound. Her movements froze abruptly.

She slowly lowered her head and saw a very thin line of blood appear on her neck.

The blood line rapidly expanded, and blood gushed out like a fountain.

"Thump." The female Dean of Students' body fell backward, crashing heavily into the pool of blood, splashing it everywhere.

Qi Yun ignored her and went to the large door.

The door to the sixteenth floor was an extremely eerie one. It was a dull bronze color throughout. Its surface was covered in dense, dark red runes!

This door felt completely out of place with the school environment, full of dissonance.

The strong premonition in Qi Yun's heart reached its peak. The key to clearing the level, or rather, the true core of this dungeon, was behind this door!

"Rumble—!!!" Beneath their feet, the entire teaching building began to shake violently!

"What's going on?!" Bai Yu frowned tightly.

Qi Yun also steadied himself, scanning his surroundings with a sharp gaze. He cast his gaze toward the bottom of the stairs.

A corpse actually moved! It was the female Dean of Students!

She wasn't dead yet?!

Her neck wound was still gushing blood, but her body was slowly, inch by inch, crawling up in a twisted posture!

"Heh... hehe..." While coughing up blood, she used her last bit of strength to say hoarsely.

"It's useless, Qi Yun. Even if you kill me, it's useless."

"I've already had people destroy the place where the 'key' is stored."

"We can't clear the level... and you will never be able to leave here either. Now, no one can clear this dungeon. Hahahaha."

While laughing crazily, she coughed up more blood, her aura rapidly fading; she was clearly at the end of her rope.

But the malice and gratification in her eyes were crystal clear.

Their mission was to guard the key and prevent anyone from accessing the sixteenth floor. But now that they had no possibility of clearing the level, they had no fear of punishment for destroying the key.

If I can't clear the level, you won't clear it either!

Destroy the location where the key is stored?

However, right in the midst of the female Dean of Students' crazy and venomous laughter and declaration, a mocking curve appeared on Qi Yun's face.

He flipped his hand. A silver-gray key, plain in design and even sporting some rust, lay quietly in his palm.

"Is this the key you're talking about?"

"!!!" The madness and gratification on the female Dean of Students' face receded like the tide, leaving only bewilderment.

She stared fixedly at the silver-gray key in Qi Yun's hand, her lips trembling. Due to the violent emotional fluctuation, blood gushed even more violently from the wound on her neck.

"No... impossible..."

"How could you have the... key... It was in the Core Room. How could you possibly have gotten it?"

Qi Yun toyed with the key in his hand, looking at her with cold eyes.

"Unfortunately. Your accomplices have wasted their efforts."

"And you can die in peace now."

"Pfft—!" The female Dean of Students spat out a large mouthful of blood, the light in her eyes fading completely. Her body "thumped" as it fell back into the pool of blood.
