Song Ziyu said it was an understatement, but how did he know the turbulent waves in Ma Senming's heart!

In the world behind this alloy door, the four generations of the Ma family have exhausted their energy to explore for hundreds of years, but they still found nothing, but Song Ziyu easily opened this door.

What is this?

Creation makes people!

Ma Senming had mixed feelings in his heart, and at the same time, he was sure of one thing in his heart. To say that Song Ziyu has nothing to do with this secret space of Longshan, he doesn't believe it when he kills Ma Senming.

……

The group entered the secret base without incident, and then began to look at this strange place.

All the spaces are wrapped in superalloy materials, both floors and ceilings.

The secret base is neatly planned, with a wide metal pavement dividing rooms from room to room, revealing many different work areas.

In Song Ziyu's view, this is clearly an ultra-modern office space, with all the characteristics of a high-end office building.

Moreover, the space here is so large that people can't help but wonder if Longshan has been hollowed out......

The lights in the hallway are all super sensitive, and they turn on one after another with the sound of footsteps.

Song Ziyu casually pushed open a door beside him and saw an empty office.

The same goes for opening the second room!

The third room is also ......

The crowd searched cautiously and found that the dozens of cubicles in the secret base were empty, except for some tables and chairs of polymeric materials that could not be taken away.

"This place should have undergone a massive evacuation." Song Ziyu expressed his judgment.

"How so?" Ma Senming asked.

"There's nothing left here, not even a piece of toilet paper, and the floor is too clean!" Song Ziyu analyzed.

"It makes sense, the environment in which normal people live is important, leaving some signs of man-made." Ma Senming also nodded.

Everyone nodded their heads, agreeing with this view.

While everyone was discussing, a slight noise came from the hallway in the distance.

The sound was almost inaudible, but the ears were sharp, and they immediately caught the sound.

There is a case!

Immediately, Xu Yingnan gestured to Tang Jian and Chen Tianxing, and the three of them started with knives and guns, and then slowly searched and moved forward in a queue of alternate cover.

After the three, Song Ziyu followed with a standard rifle.

By Song Ziyu's side, Qi Dachun and Ma Senming were also on their own alert, and finally, it was Ma Senming's grandsons Ma Xiaolong and Little Lori Antong.

As if they were facing a great enemy, they searched for the past step by step in the direction from which the sound came from.

The further you go, the louder the squirming sounds, and the more nervous everyone becomes!

Finally!

Around the corner of the hallway, you have to come into contact with something that makes a noise!

Tang Jian's bone blade was in his hand, and he rushed out in an instant, and then stood frozen on the spot.

And then there's Seo Young-nan!

Xu Yingnan's newly bought stainless steel watermelon knife stopped as soon as it was raised above his head, and this cut is not, and it is not cut if it is not.

Song Ziyu leaned over to take a look, and was stunned on the spot.

I saw that in the corridor on the other side, an oval white robot was cleaning with a broom and a mop......

"Sweep, robot vacuum?" Song Ziyu was stunned when he saw this thing in front of him!

"You know this thing?" Ma Senming asked.

Song Ziyu said: "Don't care about this thing, it's not harmful......"

Before Song Ziyu could finish speaking, the round sweeping robot suddenly looked over, and the smiling face on its belly suddenly changed from green light to red light.

"Spot the intruder and activate the sweep mode!" The voice of the robot vacuum cleaner is extremely high-pitched, like a banshee of the deep sea.

Forthwith!

Something unexpected happened!

The robot vacuum cleaner retracted his broom and pulled out a miniature submachine gun from his round belly!

Seeing this scene, Song Ziyu was taken aback and hurriedly shouted, "Run." ”

Hearing Song Ziyu's reminder, Tang Jian flew away from the spot like a spring.

Almost at the same time, crackling bullets hit Tang Jian's original position.

The bullets ricocheted and scattered on the metal walls and floors, and there was a clanging sound everywhere, and then a stray bullet hit Chen Tianxing, who was watching the excitement.

Not long after poor Chen Tianxing pulled out the bullets on his body, he was hit by a stray bullet again and was lying on the ground wailing.

The five-star hunters of the dignified hunter association, in the past two days, all the feng shui characters have gone unlucky, and they will be as unlucky as they are.

"That's enough, stop!" Song Ziyu shouted.

The red light of the sweeping robot swept over and looked at Song Ziyu suspiciously.

"Second-level administrators were discovered...... The crisis is over. ”

The red face on the robot vacuum's belly quickly turned into a green smile, then put away the miniature submachine gun, hummed a song, and went to clean up with a broomstick.

"What the hell is this...... Yes! Chen Tianxing lay on the ground and screamed.

Although the power of the stray bullet was not large, Chen Tianxing was still screaming.

Song Ziyu was also taken aback!

The dog said, equipping the sweeping robot with a submachine gun, which clever idea came up with it?

Is this a normal person's idea?

Song Ziyu settled down, but fortunately, the sweeping robot turned around and left after confirming his identity and authority, which lifted the crisis.

"Don't walk around, follow me, keep your eyes sharp." Song Ziyu reminded.

Subtly, Song Ziyu faintly had the meaning of a leader in this small escape team.

Under Song Ziyu's scheduling, everyone checked the entire space in horror.

There is nothing of value in this space except for this robot vacuum.

"Hell, it's cleaner than in a coffin." Chen Tianxing snorted in pain with another scar on his body.

The crowd fell silent again.

This space is empty, where is the way out?

Just when everyone was upset, Song Ziyu suddenly had an idea: "Follow the sweeping robot." ”

Everyone didn't know why, but they also followed Song Ziyu.

Song Ziyu hid behind the sweeping robot and followed the thing around in a labyrinthine environment.

According to Song Ziyu's understanding of sweeping robots, this guy will inevitably return to the initial position to charge after working for a period of time.

If you guessed correctly...... That initial position must be related to the exit.

Really!

After a period of "crazy tailgating", the robot vacuum cleaner suddenly burrowed into a metal wall and disappeared!

Everyone hurriedly followed, and when they got closer, they realized that the metal wall was actually ...... Lift!

That's right!

A very hidden elevator.

"Interesting." Song Ziyu pressed the elevator switch.

The elevator door opened, but everyone was stunned!

I saw a dried corpse lying in the center of the elevator.

"Don't be afraid, he's suicidal."

Tang Jian's eyes were sharp, and he saw the gun hole on the head of the dried corpse at a glance, as well as the discarded pistol on the ground.

Song Ziyu bent down and picked up the firearm on the ground, and found that it was a type that he had never seen before.

Several people enter the elevator and press the control button.

The button starts with the negative floor, and the negative floor is already the topmost floor, so the elevator runs down.

At the moment when the elevator closed, Song Ziyu saw a few big words with blood stained writing on the wall of the elevator door: Don't go down!

Don't go down?

The blood has dried up and takes on an eerie black color, which looks creepy.
