"Gollum ......"

On the "chessboard" of the main body of the instrument, the marquee-like streamer is still disordered and twitching.

The small metal ball was rolling around, and the entire instrument seemed to be in a huge, chaotic energy field.

When Lin Tuo started to probe further, a misty glow was released around the instrument, and an illusory grid covered the entire sandbox, and different areas showed different colors.

Mostly white...... This means that the concentration of aether is extremely low and stable, while the sky above the southern continent, the human sanctuary, is chaotic.

"Is there really something wrong with the shelter?" Lin Tuo's expression was solemn, and his heart was a little absurd.

What is this?

Just make the instrument, and there is a problem? Isn't that a coincidence?

"No...... Not a coincidence, the shelter was already in sync with reality a few days ago.

This suggests that the energy disturbance has probably been going on for a long time, but it has never erupted until it is monitored with precision instruments. ”

This information is critical.

If there is a threat, it is likely to have lurked in the shelter for a long time, slowly unleashing its power and spreading its influence.

This "influence" is far less intense than that of the "Prayer Candle", and is more akin to the "Secret Seal...... Of course, there is no certainty.

After all, Lin Tuo's monitoring with the instrument was only an experiment, and he wasn't sure if this thing was accurate.

Also, in case the cause of the disturbance is not a "spiritual invasion...... But something else?

You must know that after hundreds of years of development, the shelter has already applied "ether" energy to all directions of life.

For the human civilization of World 2, the ether, or "magic", is something similar to electricity.

Therefore, it is not clear whether this interference is caused by energy use.

"But I still can't rest assured...... You'll have to figure it out. Lin Tuo didn't dare to take it lightly, if it was a detection error, it was fine.

What if there is a real problem?

Similar to the Secret Seal...... Quietly in the early stage...... I can't see the signs, but I suddenly give you a big one, and that's exciting.

How to investigate?

Take advantage of the phantom space and pull in the leader to ask? No...... No way.

Assuming that danger lurks, the shelter has so far failed to respond, suggesting that they may not have noticed it themselves...... It's also vain to ask.

And it's easy to startle snakes.

In case the other party just wants to develop quietly, Lin Tuo's fierce medicine will blow up the crisis point, and it will be worth the loss.

"And...... I'm not sure if it's dangerous, and it would be embarrassing if I guessed wrong......"

After thinking about it for a while, Lin Tuo decided that it would be better to go in and investigate in person.

At the very least, find out the social environment in the shelter.

However, the shelter was hidden deep underground and heavily guarded, and Lin Tuo still needed to make some preparations if he wanted to enter quietly, and in thought, he raised his hand and pulled out a magic book from the shelf.

Turn to a page and look at the title:

Invisibility [Intermediate]

……

……

An hour later.

A palm-sized silver piece in Lin Tuo's palm erupted with a brilliant, mysterious aura, and the fine runes flew for about three seconds, and shrank back violently.

Raising his hand to pick up the other two on the table, Lin Tuo let out a breath with a smile on his face.

"Stealth Technique" is an intermediate-level spell, which can be cast with Lin Tuo's current spiritual power, but he is not proficient, so he simply sealed it into the silver plate.

Use a similar method to make a "magic scroll".

However, the material is not a special animal skin, but a silver plate, which should be more appropriately called a "magic charm".

"Three charms, even if the technique is rough and the quality is poor, but it is more than enough to support me in one action."

Lin Tuo secretly calculated, and at the same time used the system to query the ether points in his lower body, and found that the production of just three "invisibility charms" consumed him a full hundred and twenty points.

The production of the previous "Armillary Earth Motion Instrument" consumes more, a full 500 points.

It can be said that in just half a day's effort, Lin Tuo consumed half a province's ether points, what a luxury.

It's all a little distressing......

You know, he hasn't been collecting aether for a while, after all, there is not enough in both worlds...... This one can't get in and out, and the big dog can't hold it for a long time.

Thinking about danger for a while, Lin Tuo looked at the time, it was just half past seven in the evening, and he had eaten at noon, and Huaxi hadn't woken up yet, so he didn't have to worry about dinner.

Handing the charm to the clone through the sand table, Lin Tuo pulled the rattan chair and sat outside the sand table, and then raised his fingers lightly and threw the clone into the Southern Continent.

……

……

Over the southern continent, it was another cold night, and the clear sky was incomparably clear.

When Lin Tuo stepped down into the air, what he saw was the lights scattered on the huge snowfield in the darkness.

To the north, the "Wall of Miracles" and the mountains of the south protect this thriving continent.

The open sea beyond the mountains exudes a unique bright color, while on land, every point of light refers to a "vent".

Lin Tuo thought about it, chose a place to fall at random, and activated an "invisibility charm" at a height of 100 meters from the ground.

An invisible aetheric ripple rippled open, and his body instantly merged with his surroundings.

……

"Pass, go!"

The nights at the camp are always lonely, and only the occasional sound of a password indicates that there is a group of people living here.

When another huge transport truck drove out of the base, the transcendents standing guard lowered the railing with a shudder, ready to hide back in the house, but suddenly a strange feeling of being watched arose: "Who? ”

He suddenly turned his head and instinctively pressed the weapon on his waist, but where was there a half figure in front of him?

After staring around for a long time, the transcendent man rubbed his cheeks, which were flushed with cold, and smiled bitterly:

"Are you nervous?"

With that, he turned his head and entered the guard room.

"Is it the Ground Transcendent Guard? You can vaguely sense my gaze...... Well, it seems that you should be careful. ”

Ten meters away, Lin Tuo stood in place with interest, secretly alert, and then turned around to avoid the barracks area and walked towards the mountain peak not far away.

His feet were more than ten centimeters high from the ground, and he walked without leaving any footprints.

A moment later, when Lin Tuo stepped through the closed protective fence of the gate, he finally came to the "vent".

In the quiet of the night, in the huge passage like a volcanic crater, a huge turbine fan rumbles loudly, and the violent air flow is inhaled and blown out, disturbing the night sky.

Hundreds of years ago, they were called "altars".

Hundreds of years later, they were called "entrances".

No one is small in front of this magnificent industrial creation.

In the eyes of the people inside the shelter, this is the "frontier" that exists only in books, videos, and discussions, and the "frontier troops" stationed on the surface are accustomed to calling it "nostrils".

The nostrils throughout the continent support the breathing consumption of nearly 100 million people in the entire dungeon, and also assume the function of transporting materials inside and outside.

The resources collected from the outside are imported, and the garbage and waste from the city are also transported out.

It's just that at this moment, there seems to be no "echelon".

The massiveness of bare steel stood silently, bright in the searchlight above, and dark in the depths, like an entrance to the abyss.

Lin Tuo stood silently for a while, and then floated down, and with the help of his ability to step into the air, he fell towards the magnificent elevator shaft like the "abyss".

And the extraordinary eyesight after the promotion helped him to see the outline faintly in such a dark place.

Fall......

Fall......

Fall......

In the silence, the roar of the wind turbine from above faded away, and the surroundings fell silent, and after a long time, there was a light and a whistling sound under the dark feet again.

Lin Tuo listened and judged that part of it was due to the sound of the wind and part of it was from the train.

Sure enough, when he finally stepped out of the elevator shaft, he saw a huge and empty "square" scattered with some factories and containers.

Further out, there are platforms, with street lamps illuminating large sections of the tracks, and more sections drowning in darkness.

Now.

A black train slowly stopped, and then someone operated a crane and other equipment to carry the goods.

And the people in the square and on the train, the people in different uniforms of the boats, talked familiarly:

"It's late today."

"The road section in the third district of the east collapsed and was blocked for a while." The train driver replied with some unhappiness.

"Tsk, this is the third one this month."

"No, the government grants a lot of money every year, and other surrounding districts are doing well...... If it collapses again, I think sooner or later I will have to change the leader. ”

Several people around laughed tacitly when they heard this, and one of them said with emotion:

"The more you go out, the more chaotic it is, what can you do, the whip of the Central Committee can't reach it, if it's in the inner ring...... Even in Central, they don't dare to be so greedy. ”

"Who says it's not. However, it may be better to wait for a new round of public elections and a new party to come to power, doesn't it mean to improve the people's livelihood in the outer ring? ”

"Lip service, which party comes to power is not the same?"

After all, there are still few transcendents in this world, and most of them are guarding the ground.

Several people were ordinary people, so naturally they didn't notice that a transparent figure was standing curiously next to them and listening to everyone's conversation.

After a while, one person looked at his watch and said, "Even if it's late, the shuttle bus should come." ”

As soon as the words fell, a whistle suddenly sounded in the distance.

"Here, I'll get back first after work." The man smiled, said hello to a few people, and walked straight to the corresponding platform, pulling out a boarding card on the way.

Lin Tuo blinked, his footsteps moved slightly, and he followed like a transparent ghost.

After a while, an underground train carrying people came from the dark tunnel, and stopped for a short time, and two people in uniform walked down and greeted each other, who should be "workers".

Lin Tuo took advantage of the gap in the door to enter the empty subway without "swiping the card".

……

Probably because of the last section, there were very few people in the carriage, and there were only two people in this section.

As the doors close automatically, an announcement sounded in the car:

"The terminal station of this train: Xishan Road"

"Next stop: East and West Exit, open the door on the left...... Interchangeable ......"

……

"The train is running, please stand firm...... Pay attention to the safety of your feet. ”

"Vent 113 station of this station, salute the ground defenders!"
