High-level martial arts: Contract cashback, invincible starting from the Zerg.

The once pristine white planet now radiated a cold light, as if a mysterious creature were gazing down upon the world below.

Not far from the Battle Academy, a group of shadowy figures, like phantoms of the night, swiftly swept across the cluster of buildings, leaping across rooftops and flying low overhead. Soon, these mysterious figures gathered around the perimeter of the Battle Academy, as if drawn by some kind of magnetic field.

At this moment, on the third floor of the main building of the academy, two guards were chatting in the control room, occasionally glancing at the monitor screen in front of them.

"Qu Lu and his squad have gone to Yaemon again," a member of the male guard said.

The young female guard smiled, but her gaze shifted from the demon cage to her companion.

"so what?"

"So you should really suggest to your squad leader that you allow team members to date as soon as possible, otherwise, with our schedules, we'll only have two or three opportunities to be intimate a year..."

"Oh~ I really need to think about it, after all, the guys in our team are pretty good."

"Hey! If that's what you say, then I won't hold back now..."

After the male guard finished speaking, he immediately walked towards the woman with ill intentions. The woman turned off the monitoring system in the monitoring room, stood up with a tender look in her eyes, and walked towards the man.

While the two were deeply in love in the monitoring room, they were completely unaware that the gluttonous demon had turned its gaze toward the security camera. Its dark eyes seemed to be able to see the scene of their intimacy through the camera.

The Gluttonous Demon slowly stood up and walked forward.

Soon, it disappeared from the surveillance camera's monitoring range.

After the two finished their lovemaking, the woman put on her uniform and prepared to go to the living area on the third floor to change her clothes.

"Keep an eye on this spot, I'll be back later~" the female team member said quietly, while giving the male team member a suggestive look.

"Waiting for you!" The male team member smiled, lit a cigarette, put his feet on the table, and glanced aimlessly at the screen in front of him.

Just then, the phone in the monitoring room rang.

The man glanced at it, then pondered for a moment with some doubt.

"Wait a minute? It's not their turn in the schedule, so what do they want from me?" the male team member muttered nervously.

In the end, however, he still picked up the landline phone.

Teammate: "Team Leader Qu? Are you looking for me?"

Qu Lu: "Xiao Lu, was anything unusual at the Demon Cage tonight?"

Teammate: "No, everything's normal...uh...no!!"

Qu Lu: "What's wrong?"

Team member: "Let me check first. It seems that the Gluttony Demon that Chen Feng requested to be investigated is not within the scope of the surveillance."

Qu Lu: "This is unusual. When did this happen?"

Team member: "Yes, Captain Qu, I'll retrieve the surveillance footage right away and call you back soon..."

Qu Lu: "Okay!!"

After hanging up the landline, the male team member immediately began to manipulate the camera angle inside the cage, trying to find the imprisoned gluttonous demon.

However, the camera seemed to be stuck on the guide rail and couldn't move.

The male team member sensed something was wrong, so he immediately picked up an automatic rifle from the weapon rack in the monitoring room and started walking out of the monitoring room.

......

The woman was strolling leisurely down the corridor leading to the elevator, humming a pleasant melody as she went.

The sparring session between the two in the monitoring room had clearly released the pressure she had been under from the envoy for days, making her complexion rosy and her spirits look extremely high.

Squeak!

Suddenly! A strange sound came from behind the woman, as if an ancient door that had been sealed for many years had suddenly been opened, and a strange aura rushed out from it.

Ta-da!! Ta-da!!

The lights in the entire corridor began to flicker, which looked extremely eerie.

"Damn it! Who's trying to mess with me again?!" the woman said angrily, turning around to look behind her.

All that could be seen was a gap in the alloy door!

"Isn't this alloy door the emergency exit leading to the express lane?"

The woman was stunned, because she had been here for two years and did not seem to have seen this door open before. If it was just a prank, then this was indeed too much.

The corridor lights quickly returned to normal, but the alloy door still emitted a chilling, eerie aura...

Without thinking twice, the woman immediately turned around and walked towards the alloy door behind her, intending to close it again.

However, although the alloy door was only opened a crack, it seemed to be stuck by something, and no matter how hard the woman tried, she could not close it.

The woman then went around to the side and cautiously looked at the gap in the safety door.

However, thanks to the woman's heightened senses, she discovered that the emergency lights that should have illuminated the rapid transit corridor were not only off, but the area also seemed to be completely dark, with no power supply whatsoever!

The woman felt a little scared because she suddenly remembered that this alloy door could also lead to the Demon Cage on the second basement level.

She immediately turned on the walkie-talkie.

"Brother Lu, this is Xiaoya. I noticed that the evacuation tunnel door is open, but the defense system inside seems to be turned off. Have you noticed anything unusual?" the woman said.

A hissing sound came from the walkie-talkie, and the woman could faintly hear a voice that sounded like a man's.

However, the voice was extremely cold, sounding like someone had been pulled out of an ice cellar.

"Please... Xiaoya go to... for an examination... Please... Xiaoya go to... for an examination."

"That damn man, he actually made me get checked!"

A hint of anger flashed across the woman's face, but she quickly sighed.

The woman began checking the equipment on her combat suit and activated her protective force field. She then drew the pistol tucked into her waistband and entered the access code onto the keypad next to the alloy door.

Soon the words "Safely Open" appeared on the keyboard screen, but the screen still seemed to be affected by electromagnetic interference, with streaks of white silk appearing on it from time to time.

It was as if the entire space was being controlled by some mysterious force...

Boom! Boom! Boom!

As the alloy door slowly opened forward with the mechanical rotation, the entire view inside the safety passage gradually appeared before the woman.

Only then did the woman finally see the secret hidden in the darkness—it was a darkness that seemed to have a physical form, yet it appeared to conceal several evil spirits.

Just then, a cold wind seemed to sweep through the corridor, instantly turning off all the lights and burying the woman in darkness.
