"Well, I looked at it carefully, and there is no device similar to a weapon, so I guess this thing should be some control terminal...... If you're not mistaken, it's supposed to be the opening mechanism of this iron gate. ”

Raven said as he walked over to the console.

From this distance, he could see more clearly: there was a raised diamond-shaped hood with a protruding obtuse shape, and his hand had just been placed on top of it.

"Buzz! ——”

There was a small noise, like the faint sound of an electric current running on some device?

"Well, has something started?" Chen Liuwang looked around to see where the voice came from.

Suddenly, a violent vibration accompanied by a "rattling" sound of metal friction came from the raven's feet.

"Not good! Come down! Several people shouted almost at the same time.

But it was too late, and before the raven could walk away from the base disc, the thing began to rise! A puff of dust fell from the top of his head......

"Huh?"

Raven's frightened expression relaxed a little.

The disc-shaped base, along with the cylindrical machine, was slowly rising, and some light was projecting above its head—the lights of the men above. The rounded rectangular floor slowly moved downward, sliding to the side as it retreated just below the thickness of the floor.

There is no danger happening.

The sleek machine only slowly rose to the ground in the passage.

"Buzz!"

The disc base stopped moving.

Everyone looked at the dazed-looking raven standing stunned on the cylindrical console.

After about a dozen seconds......

"You're welcome back."

A female voice suddenly sounded in the empty passageway!

“……”

This unfamiliar voice was filled with the voice of a woman with a slightly jerky tone.

The sound was not loud, but in this quiet and dark space, it was as if something indescribable was striking hard in everyone's brains.

Raven was the first to react - he was the closest person to the cylinder, and he saw a screen of light in front of him flickering with a faint glow.

The figure of an amiable woman in a bizarre costume!

The blue, well-cut close-fitting uniform, somewhat resembling the outfit of the female guards in Sand City.

A wide, beautifully crafted white belt is tied over a short skirt that matches the uniform and bodice.

On his head, he wears a small round hat with a silver badge composed of eagles and shields, and his appearance is delicate and fresh......

Her face is typical of Oriental features, with her hands crossed in her lower abdomen, a gesture that is clearly some kind of formatted etiquette that has been specially trained.

"You...... Who is it? Raven asked cautiously.

“……”

“……”

The empty passage was silent at the moment.

"You're welcome back." The woman's voice rang out again!

"W-What the hell is this?"

Old Man Su said, and he had already walked out of the slope with Chen Liuwang and the others, and stood in front of the control device.

They were staring at the screen, too.

There was only a faint echo in the entire passage, and everyone gathered around, and everyone's footsteps could be heard clearly just now.

At this moment, the raven suddenly woke up!

The woman in the entire light screen in front of me actually does not exist, this is some kind of technology of the previous civilization.

This woman, every word she says is programmed in advance......

As with some of the mechanical properties of those excavated on the central continent. They don't react to your words, they just play sound and images as they were originally intended.

Sure enough, after he figured it out, the female voice sounded again!

Same tone, same content!

He took a step back and left the small platform, and the image of the woman was "whoosh!" "Disappeared in one fell swoop.

Chen Liuwang also saw very clearly that this thing was just a machine, although he had never seen this thing.

But based on his insight and reasonable speculation, he decided that this was a machine that controlled the gate.

"So, what are we going to do next?"

Old Man Su didn't dare to touch the machine, so he stood aside and asked.

Everyone was silent, standing next to the console and watching every detail with the lights.

In particular, the circular plane above the column has no extra buttons or the like, only 2 simple small screens and a strangely shaped hole.

This machine is obviously used to control the gate, and the cylinder is the control station.

But since it's to open the door, you definitely need a key or something.

So, what is the key? Also, how exactly can you start it? What kind of energy is it powered by?

Wang Hu also reached out to touch the smooth surface of the machine, and a ball of qi condensed on his hand to prepare for the unexpected.

However, nothing happened from the machine...... He fumbled around the circular plane for a while, but nothing happened.

But just as he put his finger into the hole to probe, the woman's voice rang out again.

At the same time, his fingers felt like they were being stung by something.

"Detect DNA mismatch, please try again ......"

"Huh?"

"What?"

Everyone in the silence suddenly heard the female voice, and they all stared at Wang Hu in unison!

"What did you do?" Old Man Su asked suspiciously.

"Well, I don't understand, my fingers just groped around the place."

Wang Hu watched a blood-red dot emerge from the tip of his index finger, and it was expanding into a small bead of blood!

“……”

In the quiet passage, even the sound of gasps could be heard.

"Huh? Is this thing...... Keys? ”

Raven pondered for a moment, finally as if he had figured something out.

Chen Liuwang watched the raven's long-locked brow stretch, and he also guessed a possibility from the raven's expression.

Dried blood on the ground.

Wang Hu's pricked fingers.

Quirky console, and that little hole.

Suggestive female voice.

What does DNA testing mean?

…… That's right, that's the key! The key to this console and this huge iron door.

Before everyone could figure out what was going on, the raven had already put his finger in the hole!

"The target detection match is 97%...... SNP matching degree 98.6%...... The total DNA match is 77%...... The key detection has passed, and the project authorization has been activated, may I ask Dr. Su, is it open? ”

"OMG! Authorization Initiated? ”

"Huh? Dr. Sue, open? ”

Old Man Su muttered, a hint of surprise on his face.

Except for Chen Liuwang.

The rest of the people stared, craned their necks, and listened to the quiet voice of the female voice without moving.

Only one word popped out of Raven's mind now, and he immediately shouted without hesitation: "Open!" ”

The cylindrical console light screen lit up, and a progress bar slowly extended from red to yellow to green, at the moment when the green was about to reach its brightest......

"The system has been tested...... Inadequate energy supply...... Start backup energy. The female voice calmed down.

There was a burst of "zizz! There was a sound, like electricity passing through some kind of device, and then "Bang!" Bang dang! ”

A regular sound came over the heads of the crowd.

Oh my!

The outermost layer of the huge iron door rose up with a "clang", and the letter "μ" was hidden at the top of the cave wall.

The second layer of iron wall is divided into several layers to the left and right, one layer to the back, and then the third layer. The two gears on the inside of the gate retreated about 2 meters to the rear, followed by a burst of "Bang! The sound was heard in the walls of the cave on both sides.

The massive floodgates were like the mouths of monsters, opening their teeth to reveal their dark throats.

……
