In the command hall of the Shadow Fortress, the Cambrian Mastermind, which had been behind for more than a century, was finally activated. Many small holes are opened in the metal shell of the main brain, and multiple laser beams are shot out from the inside, which together build a spherical virtual screen.

The screen is blurry and distorted at first, but gradually begins to stabilize, and the main brain behind the screen gradually disappears, and finally a spherical virtual screen is left like a space-time portal.

A top-down view of the Shadow Fortress appears on the screen, and the sharpness has improved little by little over time. Professor Herman breathed a sigh of relief, turned on his personal terminal, and began to put the finishing touches on the main brain.

Although Cambrian is backward, it is a qualitative leap for the Shadow Fortress, which previously could only rely on the miniature mastermind to handle all affairs. Even if the construction of the fortress and the dispatch of materials are counted, multiple miniature masterminds plus the commander's personal chip can barely handle it. The real role of the Cambrian is early warning and command.

In battle, Cambrian will assess the enemy's dynamics and battlefield situation in real time, make predictions, and assign combat missions to each unit accordingly. With the current scale of the Shadow Fortress of less than 10,000 people, Cambrian can completely accurately operate the war to the people. At this level of command, even Joseph and William are no match for a mastermind.

Of course, the mastermind also has its own limitations, that is, the opponent will reverse crack the inherent algorithm model of a masterbrain and develop a targeted combat model. So in general, there will be a high-ranking general next to the mastermind on the battlefield, and when necessary, the general's authority will be higher than that of the mastermind.

Of course, there is no such problem on Planet Four. The herd doesn't even know what a masterbrain is, let alone crack the masterbrain model in a targeted manner.

After about half an hour, Herman let out a sigh of relief and said, "The commissioning is all done, and it was a great success." Cambrian is now available. ”

Joseph and William glanced at each other and ordered: "Toggle the panorama mode, the range is 100 km." ”

The bird's-eye view of the Shadow Fortress appears again on the virtual screen, but this time there are two smaller screens next to it, one horizontal and one vertical, both extending underground.

As orders are given, the screen expands and the Shadow Fortress gets smaller and smaller. In the two sections, the underground part was originally completely black, but now it is gradually colored, showing the stratigraphic structure, slowly penetrating deep into the ground.

Cambrian constantly emits seismic waves into the surroundings and retrieves the signals through sensors underground. As data accumulates, panoramas grow in scope and detail becomes clearer.

William casually walked a little in front of him, and another screen appeared. The data on the screen rolled by, all of which were related to the underground structure and component distribution of the Shadow Fortress. On the side of the screen is the formation data previously obtained by manual drilling. The results of the comparison analysis of the two data are highly overlapping.

William was so satisfied that he turned off the small screen. The scope and accuracy of Cambrian detection exceeded expectations, so that it could provide sufficient warning time in the event of a beast tide, which was of self-evident significance for the defense of the base.

"Then came the limit test. The range of the first tests was 300 km. Professor Herman said.

As the command was given, the Cambrian ran at a noticeable speed and began to emit a muffled beep.

The virtual screen quickly expands in scope, and the Shadow Fortress quickly becomes a tiny dot that is almost invisible. The enlarged screen was littered with large patches of meaningless stains and patches of color, but it soon began to become clear, and the completeness of the data was rapidly improving.

After about 40 minutes, the panorama finally stabilized, and you can choose any part of it for analysis or zooming. The depth of underground structure detection has also exceeded 100 meters, and it is still extending.

Joseph switched between a few different modes at random, and after looking at it, he nodded.

Professor Herman said: "The first limit test was successful! Now the second limit test will begin, with a range of 500 kilometers. ”

The panorama expands again, and the previously clear picture gradually becomes a circle on the inside, and darkness on the outer edge.

After a few moments, the outer edge of the panorama finally reacted and patterns began to appear.

Professor Herman, who had been staring nervously at the panorama, breathed a sigh of relief and wiped the sweat that had come out of nowhere.

This time, the process of clarifying the panorama was very slow, almost jumping and refreshing frame by frame. Eventually, the outer area was mostly filled with patches of color, but there were still small black dots, which were undetected.

At this moment, the outer area is like wearing a thin veil, which is faintly unclear.

But Joseph, William, and Herman were in no hurry. As long as there is a color spot on the outermost edge, it means that the Cambrian detection range has been there, and all that remains is to continuously supplement and improve the data. That's just a matter of time.

Joseph was just about to tell a joke, when suddenly his whole body shook and he froze in place!

William was likewise turned into a statue.

They saw that at the outer edge of the panorama, a huge shadow was slowly passing by!

In an instant, their consciousness went blank as if they had been hit by something heavy. By the time he came to his senses, the shadow had moved out of Cambrian's range.

The outer edge area had been mostly probed, but after the shadow appeared, the area it passed through turned black again, as if erased by an eraser.

After a long time, there were spots of light in the black.

"What was that?" said Joseph, who first woke up from the shock.

William came to his senses after a while and said, "Do you think that thing is alive?"

Joseph smiled wryly, "I hope it isn't, but my gut tells me it should be alive." ”

Professor Herman was shocked, "If it is a living body, wouldn't its body be more than three hundred kilometers?"

Joseph froze and said, "Don't forget, that's only part of its body." ”

Professor Herman exclaimed, "How is that possible? This is the surface of the planet, and the gravity is 1.4 times that of the parent star. How could there be such a huge creature? This creature should only exist in space. ”

William sighed and said, "There are many things on this planet that can't be explained, and not this one. ”

Professor Herman suddenly remembered something, and asked tentatively, "Is this 'that thing'?"

William shook his head and said, "Actually, we don't know what 'that thing' is. Didn't they tell you anything when you came?"

Herman shook his head, his voice turned low, and said, "Who will tell him the true secret of a man who has been sent to his death?"

At this time, Joseph said: "Maybe the pace of our external exploration should be slowed down a little. Do you want to report that discovery just now?"

William pondered for a long time before he said, "Report it, it's beyond what we can handle." ”
