"It's ......"

Lin Sha's voice trembled a little, and he was shocked by the amazing scene he saw.

In the dark and dim environment, I saw a huge metal gate with a height of five meters and a width of three meters, hidden in the surrounding solid rock wall, with a clattered surface and a gray color, almost completely inseparable from the surrounding environment.

If it weren't for the dimly lit environment, the metal door was particularly conspicuous with a little bit of light, and it would have been really difficult to spot it at the first time.

It took a lot of effort to open the metal door that looked like a rock wall, and a long metal tunnel came into view.

......

At this time, he was already dozens of miles underground, going down the crater that had already solidified, but he did not expect to find a man-made wide passage under the volcano.

With the technological level of the Berserk Empire, it is not difficult to build a passage more than ten miles underground, but it is rare to build a secret passage under an active volcano, and a single protection problem is not so easy to solve.

A few days ago, the volcano erupted, and the magma gushing out of the crater rushed into the air for nearly 100 meters, which shows the strong internal power of the volcano. There is also a golden red magma with a high temperature of thousands of degrees and a long time, and Lin Sha estimates that even if the energy protection of the small spaceship he is riding on is fully turned on, it will not last long.

But the underground passage under him not only carried it, but also the surging magma river not far away, emitting a blazing heat that destroyed everything, kept washing the thick rock wall on one side of the passage.

I don't know how this spacious underground passage was built, and the all-metal result must have been done by the forces of high civilization, but I don't know which one has such a big deal?

It is indeed a big deal, and it is necessary for Nima, such a barren and abandoned planet, to waste material and financial resources so vigorously to build an underground passage at the bottom of an active volcano?

That's not how money is spent!

Looking at the flickering light, the dust has not yet shone, and people don't know how many metal passages there are, Lin Sha hesitated for a moment and didn't know whether to step inside.

Constantly pressing the one-man energy detector in his ear, together with the spaceship's main control optical brain, scanned the metal channel in front of him back and forth, but found no abnormality.

But for some reason, Lin Sha felt a wave of uneasiness in his heart, feeling that the metal passage in front of him that stretched out somewhere was very dangerous, and he might risk his life if he dared to step in!

Since his combat strength exceeded five hundred, he found that there were many inexplicable changes in himself, such as his five senses were much sharper than before, and he could vaguely sense danger in advance, in short, with the improvement of his own strength, many gratifying small changes have occurred in him.

As a fighter, whether he follows the principles of the Dragon Ball manga or not, he is convinced of his peculiar senses, and sometimes he doesn't even believe in high-tech equipment that doesn't lie, he hasn't been so crazy, but as his combat effectiveness continues to improve, many of the facts confirmed by his keen perception have to make him think a little more, and weigh the price he needs to pay for the adventure.

There have been so many things like this, so he can't help but be careless, if he loses his life because of his own carelessness, he won't be able to do it.

He is not a fool, it is very strange to be in this star field, and the barren planet he is on at this time is also a bit mysterious, and he doesn't want to risk his own life until he knows the general situation.

To go in? or not to go in?

To be honest, it was a surprise to be able to suddenly see the unique means of high-tech civilization on this barren planet where birds don't.

Nima's, he took great risks to go deep into the interior of the active volcano that had just erupted, but he was always worried that the active volcano would suddenly erupt without giving face, and he would not even have time to run at that time.

He didn't practice any Vajra Immortal Skills, and when he encountered a volcanic eruption, he was blazing at a temperature of more than 1,000 degrees, and he didn't have any resistance at all, and he would be turned to ashes in an instant!

Of course, it is undeniable that he is very curious about the mysterious metal passage that appears in front of him.

I don't know what secrets are inside, the technological level of the metal channel maker is not weak at all, at least after the analysis of the Feiyun master control optical brain, in some aspects, it is not even weaker than the imperial technology, which is very remarkable.

Although the Berserk Empire is respected for its strength and is not a pure technological civilization, it has done a very good job in absorbing and embracing the advantages of technological civilization.

According to the Empire's public information, among the hundreds of nearby civilization systems, the Empire's technological level in life is at least at the forefront of the interstellar, of course, military technology is definitely inferior to those pure technological civilizations, this is a certain thing, the Empire is also very calm about this.

Anyway, the most important thing for the Berserk Empire is individual strength, although it can't build that kind of interplanetary super star battleship, but the strength of a single body will not be afraid of these side giants at all.

To be able to build such a huge metal passage at the bottom of an active volcano on such a barren planet, the strength behind the builders can be imagined.

You know, this is not an area of direct radiation from the interstellar passageway, and most of the materials needed to build an underground passage of this scale have to be transported through interstellar transport ships, which is staggeringly expensive.

Lin Sha had done his homework three days before he set off, and the new interstellar passage from the Imperial Main Star to the Colonial Mine Star had not been opened for more than a hundred years, and during this time, he had not found any signs of major moves in the nearby star fields.

You must know that every public interstellar channel and the surrounding star fields are closely monitored by various interstellar forces, and there is no chance for any force to secretly make big moves!

Since there has been no sign of any interstellar forces making big moves in the nearby star fields in the past hundred years, the huge underground passage of the active volcano on an inconspicuous and barren star in this strange star field is worth playing.

Is it any wonder that a hundred years ago, before the nearest public interstellar passage was opened, powerful interstellar forces secretly came to arrange it?

Why are they building on such a desolate planet?

What is their purpose, or is there a benefit to this inconspicuous and barren planet that is worth making a big deal about?

Although he didn't know much about the methods of the interstellar forces of all sides, Lin Sha understood one thing, the so-called unprofitable things cannot be done early, and the interstellar forces of all parties would not spend a lot of money to do things that were not beneficial!

The most bizarre thing is that there are interstellar forces who have spent a lot of money to build a huge passage at the bottom of the volcano on the barren planet where they are at this time, but the spaceship he took traveled all the way to the periphery of the planet, and sent more than a dozen reconnaissance robots to scout on a large scale, and then he personally went down to the surface of the planet to conduct direct exploration.

So many actions have not been hidden, if there are other interstellar forces on the planet, Lin Sha is estimated to have died more than ten times now, how can he still look at the huge passage at the bottom of the active volcano and wonder if he should go in?

Thinking of the terrible place, he couldn't help but shudder, afraid that something would happen to him and he couldn't get out of this place, so his body soared into the sky, planning to leave this dangerous and strange place as soon as possible.

......

After returning to the spaceship, Lin Sha immediately took off his tight-fitting biochemical combat suit and sent it to the spaceship's cleaning cabin for disinfection, before turning around and returning to the spaceship hall.

The small spaceship was still parked in the low earth orbit of the barren planet, and it did not land on the surface of the planet with him just now, and he also took a careful precaution.

"Light brain, have you found out the specific location of that life fluctuation?"

The sudden appearance of the situation caught him off guard, and he asked in a somewhat annoyed mood.

"Report to the captain, the source of the fluctuations in life during the previous eruption has been determined!" replied in a dull voice from the ship's light brain.

"Oh, isn't it in that underground metal passage?" Lin Sha asked urgently.

"Yes Captain!"

"Where does the metal passage lead, has the light brain detected it?" Lin Sha continued to ask.

"No!" the spaceship light brain replied still dullly: "That underground passage is covered by a special magnetic field, and the spaceship equipment cannot detect its existence!"

"Is there a way to investigate?" Lin Sha asked without giving up.

"The reconnaissance robot must be sent directly inside to collect the first information, otherwise the spacecraft has no way!"

"Then what are you waiting for, send the scout robot to it?"

......

"Report to the captain, report to the captain, all the dispatched reconnaissance robots have lost contact, and all the dispatched reconnaissance robots have lost contact!"

Lin Sha was forcibly pulled out of the virtual real world by the spaceship's main control optical brain, and what he heard was such bad news.

Is there any mistake?

His face darkened, and he asked angrily, "What's the matter, how did the reconnaissance robot lose contact?"

"Report to the Captain!"

The spaceship replied with a dull light-brained mechanic: "An hour ago, the spacecraft sent two groups of four reconnaissance robots to the bottom of the active volcano to investigate, and there was no problem from the crater to the bottom of the volcano, but as soon as the reconnaissance robot entered the underground metal passage, the signal was unstable!"

"Is it just that the signal is unstable?" Lin Sha was very skeptical.

"More than that!" the spacecraft's main controller, the optical brain, gave a negative answer: "Before the reconnaissance robot could advance a hundred meters, it was all destroyed by a sudden attack!"

Sure enough, that underground metal passage is in danger!

"Is there an image sent back, let me see the situation!" Lin Sha's face was calm, he had already been mentally prepared for this, but he was more curious about the situation in the underground metal passage.

After receiving the order, the spaceship's main control optical brain raised a large light screen without saying a word, and a series of clear images of reconnaissance robots descending on the surface and probing from the active crater to its interior appeared on the screen.

As the reconnaissance robot went further inside, the picture fluctuated more and more, and the portrait less than 100 meters away had been divided into disconnected fragments, and a posture that could collapse at any time.

And at this moment, a sudden change occurred, and four white lights flew out of nowhere, and then the picture went black and there was nothing......
