Not only was the huge red lamp brightly shining, but there was also an extremely sharp sound. The next moment, several huge metal creatures rushed towards this side.

Vanessa wanted to move quickly in stealthy state with [sprint] and leave this weird thing. Who knew that a flashing [flare] shot out from Yao Yaoling's arm, illuminating everything within a few meters as if it were daytime.

It directly cracked Vanessa's invisible state.

"Ah!" Little Vanessa finally screamed in shock.

The metal creatures also came, but they all stepped on Aurelia's trap and turned into large chunks of ice.

At this time, Duke shot a [Ice Arrow] and frozen the demon spirit into a large piece of ice.

Suddenly the entire huge steel passage returned to peace again.

The astonishment on Vanessa's face had not subsided yet. It was obvious that she could not accept that her stealth had been cracked by such a strange thing.

Duke asked Aurelia with a smile: "How is Little Vanessa's sneaking level compared to that of a troll?"

"At least, better than 80% of the trolls."

“That’s enough.”

"Enough?"

"Enough!" Duke said with great certainty.

Sniffing in the air, Aurelia pointed directly at the end of the passage: "Where does it seem like there is a guy who can be called the boss."

Duke smiled: "No matter what. My goal is not this."

Duke walked over, relieved Yaoyaoling's freezing, and then pointed at Vanessa, who was skillful and skillful, to dismantle the mobile alarm robot.

A large string of data is on Duke's retina.

"You have obtained the preliminary structural drawings of the [Mobile Alert System]."

In fact, this is not completely correct. As a university student engaged in construction equipment, Duke has already made the structure of Yao Yaoling a lot.

In general... Dwarfs are really geniuses!

He actually used the technology of the Steam Age to use automatic control technology. The crazy enemy-seeking system was actually shock-induced heat-induced. This technique is like Tesla, Edison, and Einstein, who have transcended the limitations of the times.

Of course, it is not that Yaoyaoling's technological content is so high that it is explosive. It is because the dwarf used many simple, violent and miraculous devices when he designed this thing.

For example, this vibration sensing is actually similar to the ancient "seismometer" before Duke's time travel, but it is more exquisite. It is actually the gap between Yao Yaoling and his gears to start vibration sensing with his gears. In that short gap, no one would realize that it was actually sensing vibrations within a diameter of dozens of meters around it in a static state.

Once there is a vibration, it will enter the next stage.

Tested with a thermal sensing stone. When it passes again, a flare will be automatically fired in the direction of the heat source to further confirm whether the target is invisible or in a concealed state.

Three types of confirmation ensure that you will never be misjudged.

Finally, there is the crazy high-frequency speaker alarm.

In addition, it is an unscientific and magical power system.

A [Mobile Alert System] robot comes out.

Duke did not go to the Final Boss, and cleaning up Nomorigan was not an easy task. In addition to cleaning up the big traitor of the dwarf, he also had to block all the gaps between the rocks and clean up not too weak radiation. Duke did not have the spare time to do this.

So Duke took two women and entered the engineering laboratory directly.

One day later, Duke returned to his private army and brought back a large number of the latest models of Yaoyaoling.

"System Elf, are you sure this thing is fine?" Duke had deep dark circles and had a visible fatigue on his face. But in order for the 30,000 troops to be no longer constrained, everything was worth it.

"Dear host, I'm extremely sure. All gravity sensing settings have been set to 150 kilograms, and only humanoid creatures that exceed this number will trigger the alarm. And according to the host's habits, I set the most eye-catching warning sound for Yaoyaoling."

"That's good."

Duke almost emptied the entire Nomoregan engineering laboratory. It is estimated that McNeil, the traitor who betrayed the great craftsmen and all the dwarfs, might go crazy on the spot when he discovered it.

So, after Duke gave a little explanation, the army drove again.

Few people know that there is actually an engineering laboratory on the fourth floor of Normoregan. No one knows that Duke has made something in that laboratory and moved the lab to Carrazan.

The soldiers of the Storm Kingdom looked curiously at a large number of strange mechanical things with tree bark on their heads and ran around the army.

"Dieda" makes a strange noise.

Then there was no effect until that night.

Windersol was puzzled by Duke's arrangement, leaving only a minimum sentinel, but instead arranged a "rapid response force" of at least 200 people. It was a cavalry that was prohibited from sleeping all night, equipped with a lasso that was strangely involved in the wire? A long-handled battle axe that was rarely used by cavalry?

What the hell is that?

"Well, I've been in the army for so many years. It's been almost two years since I heard such a strange order that made us 'chasing' the trolls after hearing the alarm in the middle of the night. Is it better to live?"

"I heard that the trolls don't cut off their heads or penetrate their hearts directly, and they will basically heal their injuries after a while?"

"Yes, there are basically no trolls near the Elvin Forest, only a few occasionally near the Night Forest. But in the Lordaeron Continent, trolls are the norm, right?"

"What is the alarm?"

None of the cavalry knew about it.

At night, they soon knew what the alarm was.

Suddenly, in the dark night, they heard a shrill cry for help.

"Help, kill people, why do you want to dismember me?"

Every cavalryman has a capital letter "囧" on his face. If he is calling this, he will certainly have no problem. The problem is that the call is obviously an electronic sound full of mechanical smell.

Since this was the order from the superiors, the cavalry quickly moved out. When they arrived, they found a strange "Yao Yao Ling" with a red alarm light flashing, which was being chased by two trolls.

"Come and save the car! Someone here is showing off! The scene can't be held."

As he shouted the so-called words, the robot tried hard to run with his short legs. Originally, it could not run away from the troll, but when the troll saw the cavalry reaching, he immediately ran back.

Chasing the trolls who are hidden masters in the dark is a terrible thing, and they will be killed in minutes.

At this moment, the cavalry laughed.

I don’t know what special paint was sprayed on the troll, but even in the dark night, there was still extremely eye-catching fluorescent light. The troll seemed to want to wipe it off, but the more I made it, the bigger the lump.

After losing the hiding, two ordinary troll scouts were suspense when facing the fierce cavalry of a squadron?

The next morning, the entire army saw the spoils of the Rapid Reaction Force. (To be continued.)
