The Black Domain is a planet that is almost forever immersed in darkness, and due to the special convergence of tides, this place has gradually prospered and gradually developed into a "star of wealth" based on trade.

That's right, "Black Domain" is not the planet's original name. At one time, it was called the "Black Venus".

With the accumulation of wealth, the star thieves gradually became active on the star path around Black Venus, and gradually formed several groups of thieves who were quite successful.

Then the war between Black Venus and the Star Thieves broke out, and the result was ...... The Black Venus Alliance returned with a great victory without any suspense, sweeping away the large number of star thieves around them!

However, the good times did not last long, and another wave of star thieves appeared around Black Venus.

At first, this group of star thieves was just a group of last thieves who gathered a few lost dogs, but for some reason, this group of star thieves turned into a behemoth in a short period of time!

Black Venus naturally would not let it go, and sent troops again to try to exterminate this group of star thieves.

Just when everyone thought that this group of star thieves would be easily wiped out, the appearance of a high-ranking war spirit changed everything.

The high-level battle spirit swept the high-end combat power of Black Venus, and single-handedly occupied the "Drain Zone" of Black Venus, and then ...... Countless warbands that were more elite than the regular troops of Black Venus appeared.

No one knows where these elites came from, only that they easily wiped out the Black Gold Star Alliance.

The name of this group of star thieves is Black Sail.

Before Black Sail became the master here, the underground world of Black Venus was already quite large.

The so-called underground world is composed of hydrothermal pipes, power pipes, and water and sewer pipes. Among them, the hydrothermal pipeline is the deepest, followed by the upper and lower water pipelines, and the power pipeline is the shallower.

After Black Sail became the owner of Black Venus, there were several more underground pipes, coupled with the continuous growth of buildings of various forces, abandoned basements, underground corridors, construction leftover spaces, etc., which made the underground world more complicated.

At this time, in this dark world of pipelines, a figure walked through it quickly, tossing and turning in this place where he couldn't see his fingers, and his speed did not decrease at all.

"Turn left at the front mark...... Turn left and go straight...... Jump over ...... ahead."

In the shadow's headphones, an electronic synthesized voice kept prompting.

It was precisely by virtue of its guidance that the figure could move so smoothly through this complex pipeline.

“…… The second pipeline is ...... Walk through and you'll be in the shielded area...... Beware of 'patrol eyes'. ”

"Okay, BT. Wait for me. The shadow whispered, a thin voice that seemed to be a woman.

"Good luck."

Communication was lost.

The shadow followed the last hint.

The passage ahead was getting narrower and narrower, and sometimes it was even necessary to drill to get through, but it didn't bother her, and she walked through the vast labyrinth like a ghost, heading towards her goal.

After dodging a few 'patrol eyes' peeking into the pipe, the shadow finally stopped, carefully pasted a palm-sized instrument to the wall next to it, and quietly listened to the sound coming from the headphones with bated breath.

“……”

After a few minutes, the shadow didn't seem to notice anything wrong, pulled out a ballpoint pen-like thing, and pressed the tip of the pen against the wall.

"......"

Bursts of blue light peeked through the ballpoint pen and sank into the metal walls. The seemingly solid metal wall slowly turned red, softened, and finally fused.

In this way, the ballpoint pen walked around the wall and drew a "window" that could accommodate people.

Shadow put away the "ballpoint pen", took out a handle from his waist and pressed it against the wall, and then pulled it back, and the thick iron wall was dragged down.

The slender shadow first looked inside, reached out and stuck something on the hole, and then the whole person slipped into it like a snake.

"Is it here......

The shadow whispered to herself.

The inside of the wall is clearly a vault.

Countless locked drawers and huge, heavy safe doors fill the space.

The figure reached for a row of cabinets and counted the numbers in the small drawer above.

“1023…… 1024…… Got it. ”

I didn't see her make any moves, but I saw Safe No. 1024 open with a "click".

"Well done...... BT。 The figure exclaimed, reached into the safe, and pulled out the contents one by one.

“1、2…… 5、6…… Hey? Gone? …… Why is one piece missing? "There's something strange about the shadows.

"Forget it, whatever." Shadow casually placed something in Safe 1024, and the safe clicked and locked again.

Suddenly, a piercing siren sounded!

"Discovered?" The shadow frowned, and a few jumps came to the entrance of the hole, and the figure was short.

As the shadow came out, something she had previously attached to the entrance of the cave lit up, and then dimmed again.

The shadow ignored that, and ran out of the pipe as fast as he could.

"Boom ......"

A muffled sound came from afar, and although the sound was a little strange due to multiple reflections, it was still audible that it was an explosion.

"It's pretty fast."

The dark shadow muttered to herself, and suddenly, there was a "swish" electric sound in her headphones.

“…… BT？ Are you at war?! ”

"Yes, I'm 120 meters above you." The electronic voice replied.

"Fighting spirit?"

"Yes."

At the same time, a raging warrior figure passed through the data link.

"Imperial Standard Battle Spirit Armor...... Hehe, you dare to wear it openly......" The shadow shook his head and ordered: "BT, the virtual light cannon, aim 20 meters in front of me." ”

"Yes."

With the answer of the electronic sound, a dazzling pillar of light suddenly lit up in the dark cave!!

A sun-like pillar of light flashed and then vanished, leaving behind a cylindrical crater with a diameter of more than 5 meters!

The shadow accelerated in a few steps, and suddenly jumped into the huge pit in front of him, two points of light flashed under his feet, and then the shadow swayed upwards and rushed out of the pit in an instant!

"I'm coming, catch me."

In mid-air, the shadow's body stretched out, revealing her perfect figure, with a furious peak, a slender waist, and slender legs...... Although it is just a silhouette, it is enough to make people's hearts ripple.

In the next moment, a behemoth opened the lid and swallowed the beautiful shadow, and the surrounding area of the shadow was suddenly dark.

"Command transfer **** back, sir."

As the electronic sound sounds, the triangular screens in the dark space light up, forming an outside scene, making people feel as if they are in a transparent glass ball.

Outside the "glass ball", the humanoid machine that swallowed the black shadow suddenly became nimble, and a skilful parry counterattack knocked the giant of its size to the ground.

……

At the same time, on the square.

The technician who was debugging the directional tidal gate suddenly shouted: "What's going on!?" I didn't move! How did you start it yourself?? ”

As soon as he finished speaking, the armillary sphere-like metal circles began to glow, and then a deep vortex appeared in the middle of the tide gate!

At the moment when the whirlpool lit up, a huge robot flew over from the other end of the square! Dive headlong into the maelstrom!

Before the robot could disappear, three jars more than one person tall fell from its waist.

"Bell Bell Bell ......"

"Not good...... That's ......"

"Boom ——————"
