"All right, this is too troublesome! Why do I need to get out from the entrance when I can make my own way out from here?!" Instructor Mei Lan said as she started to crouch.

Instructor Mei Lan put most of her strength on her feet and jumped straight upwards!

Her slender body flew upwards with an amazing speed just like a cannon shell launched from below.

Just when Instructor Mei Lan's face almost crashed onto the stone ceiling filled with deep cracks, she struck out her fist forward toward the stone ceiling!

[Demonic Tune] variation move: [Grinding Strike]!

BBBOOOOOOOOOOOOOMMM~!!!

When Instructor Mei Lan's slender fist almost touched the stone ceiling, the intense air vibration around her fist already ground the stone ceiling into dust.

Instructor Mei Lan did not just stop until there. 

Her slender body kept shooting upwards while the intense air vibration around her fist burrowed a hole in the stone ceiling for her to go through.

The underground dungeon was located hundreds of meters under the ground, but Instructor Mei Lan planned to burrow a hole with her [Grinding Strike] until she went back out.

Of course, she could not jump that high. Instructor Mei Lan immediately lost her momentum and almost fall back down, but she swiftly took out a flying disc from her space pouch and used it as her foothold.

Instructor Mei Lan controlled the flying disc under her feet and flew upwards again while kept using her [Grinding Strike] to continue burrowing a hole upwards.

It did not take long for her to see a glimpse of light in front of her.

BBBOOOOOOOOOOOOOMMM~!!!

Instructor Mei Lan jumped out from the hole she made as she reached the surface.

She took a deep breath in relief when she finally saw the blue sky above her again.

"Eh? I wonder where are Bingbing and Silly Fox right now? I hope they manage to go out by now. I will be a huge pain if I must go back to save them." Instructor Mei Lan murmured as she put her finger on her chin.

[Heavenly Sound] detection move: [Sonar]!

Instructor Mei Lan immediately detected the location of Bing Yi and Hei Yinghao with her [Sonar].

Both of them were still inside the underground dungeon, and they were currently still climbing the long spiral staircase. 

It took them several minutes for them to descend from that long spiral staircase before, but it was because Instructor Mei Lan intentionally slowed down her step just so Bing Yi and Hei Yinghao could easily follow her from behind.

If Instructor Mei Lan was alone, she could go through this long spiral staircase easily in a few seconds.

Right now, Bing Yi and Hei Yinghao still faced a lot of difficulties because of the dangerous traps placed on this long spiral staircase, while the underground dungeon already started to collapse behind them!

"Ice Girl, we are running out of time! Can you lead the way faster?!" Hei Yinghao complained to Bing Yi with an irritated tone.

"Shut up! Why don't you just be the one who leads the way if you want to do it faster than me?!" Bing Yi angrily shouted at Hei Yinghao.

Hei Yinghao could not remember the correct sequence section in every rung like Bing Yi. That was the reason why Bing Yi was the one who led the way right now.

But no matter how good Bing Yi's ability to remember, she only saw Instructor Mei Lan going through this long spiral staircase once. Moreover, she needs to recall the section sequence in reverse because they were not descending the staircase like before, but they were currently ascending the staircase right now.

Bing Yi's mind already pushed to the limit right now, but she still needs more time. 

Meanwhile, the earthquake got more and more violent. The speed of the underground dungeon collapsing also became faster and faster.

The deep cracks were already spreading everywhere.

Huge debris kept falling from the collapsed ceiling.

Many stone walls already began to crumble apart.

All of those got closer and closer to Bing Yi and Hei Yinghao's location.

Just when the deep cracks started to spread on the spiral staircase below their feet, Hei Yinghao finally decided to make his move.

Hei Yinghao held Bing Yi's smooth hand and pulled her closer toward him.

"What are you…" Bing Yi shouted angrily at Hei Yinghao, but before she could finish her words, Hei Yinghao already carried Bing Yi away in the princess carry style.

"We are running out of time! Hold on tight and grit your teeth! I will not take any responsibility if you bite your own tongue!" Hei Yinghao warned Bing Yi with a stern tone.

[Blood Burst] active!

[Blood Ignition] – Twelve Amplification active!

Hei Yinghao activated both of his [Blood Burst] and [Blood Ignition] at his utmost limit in that instant!

Hei Yinghao's figure turned into a black flash as he ascending the spiral staircase with lightning speed!

He did not bother to care anymore about the dangerous traps placed on the spiral staircase.

Every time Hei Yinghao stepped onto the next rung the dangerous traps were triggered.

Hundreds of poisonous arrows shot out from the wall, flame wall, sharp spikes appeared on the ground, trap holes, landmines made from exploding talismans, and many other types of traps more...

However, Hei Yinghao was moving way too fast, so when those dangerous traps triggered, he already went more than ten steps away from it.

"GGGUUUUUUOOOOAAAAAHHHH~!!!" Hei Yinghao shouted out loud as he pushed himself to past his limit.

His main problem was not those dangerous traps anymore, but the collapsing underground dungeon!

No matter how fast he sprinted, he could no longer keep up with the speed of the underground dungeon collapsing!

The spiral staircase, the stone wall, and even the ceiling already started to fall apart!

Hei Yinghao threw Bing Yi onto his left shoulder and carried her like a sack now. He used his left hand to hold Bing Yi's buttock, while started to accumulate the black destructive energy on his right palm.

[Destruction Force]!

"Bast*rd! Pervert! Where do you think you are touching me?!" Bing Yi gritted her teeth in anger and embarrassment as she cursed Hei Yinghao out loud.

Hei Yinghao did not have any time to think about Bing Yi's shout, he kept accumulating the black destructive energy with his [Destruction Force] divine ability while kept sprinting at his full speed.

RUUUMMBLEE~!!! RUUUMMBLEE~!!! RUUUMMBLEE~!!!

The earthquake got much more intense as everything around them crumbled apart!

Hei Yinghao swiftly jumped when he reached the top of the long spiral staircase!

Right when he managed to go through it, the long spiral staircase finally could not hold on anymore and fell apart, shattered into pieces, then fell onto the bottom of the underground dungeon.

Hei Yinghao did not stop and kept on running. There was still the long dark corridor filled with dangerous traps in front of him.

But it seems their time was up as the ceiling above them had finally collapsed!

There was nowhere for them to run anymore!

Everything around them already collapsed at the same time!

If they did not do something right now, Bing Yi and Hei Yinghao would certainly be buried alive in here!

At this critical moment, Hei Yinghao chose to inject his vitality energy into his black cloak.

There was a pair of black wings appeared on his back, and he hastily used it to fly upwards in that instant.

Just when the huge rubbles from the collapsed ceiling almost squashed him and Bing Yi, Hei Yinghao waved his right palm and unleashed the [Destruction Force] accumulated on his palm.

The black destructive lightning flashed on the top of his palm as Hei Yinghao converted the accumulated black [Destruction Force] into even more violent and powerful [Lightning of Destruction]!

BBBOOOOOOOOOOOOOOOMMM~!!!

The extremely powerful and destructive black lightning destroyed everything on its path.

The huge rubbles and the cracked ceiling had turned into dust the moment it touched the destructive black lightning.

Unfortunately, the strength of Hei Yinghao's [Lightning of Destruction] lied in its lethality, unlike Instructor Mei Lan's [Grinding Strike] which had a high penetrating effect.

The good news was Hei Yinghao already so close to the surface when he already climbed up the long spiral staircase, so his [Lightning of Destruction] still had enough power to bring him and Bing Yi to break onto the surface.

BBBAAAAAANG~!!!

Hei Yinghao took a deep breath when he finally broke out to the surface and saw the blue night sky above him!

But the extreme exhaustion started to assault his body when he relaxed for a bit.

Hei Yinghao's consciousness began to fade away, and he fell into a deep slumber.

"Wa… Idiotic Silly Fox! Why do you sleep now?! We still need to fly right now!" Bing Yi already separated from Hie Yinghao, and she activated her black cloak too and flew above the collapsing ground, but Hei Yinghao plunged down instead right now.

Bing Yi gritted her teeth and reluctantly caught the falling Hei Yinghao before he dived back down onto the collapsing ground.

Since the underground dungeon already collapsed, the ground around here had lost its support and already started to cave in, then sank deeper down.

The old-looking temple near them had already long fell apart because of an intense earthquake.

Even the guards there already dispersed, and they might already notify their higher-ups about this.

Bing Yi held the unconscious Hei Yinghao by his collar while kept staring at the collapsed ground with a worried expression.

"I hope Instructor Lan already went out from there…" Bing Yi murmured, but before she could finish her words…

"Oh, sure! I already went out from there long ago! How can you two be so slow?!" Instructor Mei Lan complained from behind Bing Yi.

Bing Yi turned around in surprise to see Instructor Mei Lan.

Instructor Mei Lan already sat leisurely on the top of her flying disc while staring at Bing Yi and Hei Yinghao with a gentle smile on her face and said: "It seems I need to increase your training a lot more later. Ah, well… this is not the right time for us to discuss this."

Instructor Mei Lan ended her speech as she glanced around.

There were 70-100 people or maybe more already surrounded them from all directions with angry expressions.

All of them stood on their flying swords, while Instructor Mei Lan sat on her flying disc. Bing Yi still carried the unconscious Hei Yinghao and hovering with the pair of wings from her black cloak.
