"There is a biological civilization!" Cao Xiaoke jumped up first: "We must report immediately!" ”

Song Zixiao was quite calm, he waved his hand: "Don't make a fuss, I've seen faces on other planets, but in the end it was just a false alarm." Pen? Interesting? Pavilion wWw. ｂiquge。 infoHave you all forgotten the first law of the expedition? It's not on Earth, don't use Earthly thinking to understand anything outside Earth. ”

Having said that, except for Song Zixiao and Gao Ji, the faces of the other three were still ugly.

Cao Xiaoke asked, "Then what should I do next?" Send another reconnaissance plane? ”

Song Zixiao shook his head: "The camera of the reconnaissance plane is too bad, send a Leopard scout to ......"

Wang Xiaoshi interjected: "Leopard? The snow outside is only half a meter deep, and the suspicious location is close to a hundred kilometers away from us, so it will take at least four or five hours to run through it in a leopard style. ”

Song Zixiao glanced at him: "Do you have a better way?" ”

Wang Xiaoshi smiled: "I think it's better to let the construction robot go, the crawler is more reliable than the limb forward, it is estimated that the time can be shortened by at least half, and in case of any accident, our already pitiful combat effectiveness will not suffer losses." ”

Song Zixiao pondered for a moment, and then looked through the window at the crawler robot outside that was reinforcing the door of space. The so-called reinforcement of the spatial door is to support the spatial cracks they pass through with an alloy frame made of nanographene to prevent the cracks from closing due to slight spatial fluctuations. After all, it takes a certain amount of resources to open a space channel each time, and the alloy frame of nanographene can be recycled.

Seeing that the installation of the alloy frame was nearing completion, Song Zixiao nodded and said, "It's okay, Xiao Shi controls a crawler robot to go to a suspicious location for urgent reconnaissance." In addition, the spare construction team was also released to carry out the construction of base defense; The rest of the combat teams in the storage bin are put on standby; Luo Wenjun turned on the base defense system, and the radar and protective shields, as well as the defensive weapons, were all put into a state of readiness. ”

Cao Xiaoke licked his somewhat dry lips: "Boss, do you think there is something wrong?" ”

Song Zixiao patted him on the shoulder: "Don't think about it, this is called being careful to sail a ship for ten thousand years." ”

Wang Xiaoshi put the combat helmet back on, which will help him gain an immersive view, and at the same time, the real-time monitoring screen on the electronic screen is not turned off for others to see.

A crawler robot outside the base broke away from the construction team, and under the control of Wang Xiaoshi, it ran through the thick snow and set off in the direction of the black quad.

Like the old combat robots, these tracked robots are older than they are, and don't even have an official name. Even in the 21st century, it is difficult for people to associate this robot with the general impression of high-tech robots, and it is more likely to associate it with the loading and unloading truck in a supermarket warehouse.

It's like a small, dilapidated excavator, except it doesn't have a cockpit, and above the tracks is a flat metal platform with metal tentacles that replace the excavator's boom. In the normal state, it is only 1.5 meters long, and even when extended, the maximum length and width are only 3 meters. This humble shape is obviously why it is easy to be looked down upon.

But in fact, as the **** old saying goes, the beauty of connotation is the real beauty.

First of all, as the first generation of ancient technology under the sea, its material, not to mention the excavator, even if the most advanced bulletproof vehicle in the 21st century collides with it, it may not be able to take much advantage. The tracks, pedestals, and metal platforms of the crawler robot are made of gold osmium, and the four metal tentacles at the top of the metal platform are made of alloy chromium, the longest of which can reach 15 meters, and the shortest one is also 5 meters long. The maximum power of the four tentacles can easily lift items weighing up to five tons.

Don't look small, but the weight of the whole vehicle reached 11 tons, which was enough to cause people to exclaim in the era when it was just born.

So, don't discriminate against it because it looks ordinary, although it is outdated now, but it was once a king.

Under the control of Wang Xiaoshi, the four tentacles of the crawler robot stretched together in front of the car body, like four sharp knives, easily crushing the snow on the ground in front of them. Without the interference of snow, the crawler robot quickly reached its optimal speed of 60 kilometers per hour.

From a distance, the crawler robot running wildly in the snow looks like a snow-spraying glider, raising snow waves several meters high behind it.

More than an hour later, the crawler robot approached the black quadrant. The 3D camera allows several people in the command room to clearly see everything in front of the crawler robot.

It wasn't a black quadrang, it was a huge square opening. There seems to be some kind of magical power inside the entrance of the cave, as there is no snow inside. And this is obviously not the cause of geothermal snowmelt, because if the temperature inside the cave is enough to melt the snow, then the strong temperature difference at the cave entrance will cloud the camera with a layer of moisture.

The previous unmanned reconnaissance aircraft did not see a horizontal line, but a huge step. Although the staircase is so huge from a human point of view that it really doesn't look like a staircase, the nature of the sequential downward extension cannot be explained.

Wang Xiaoshi compared the height of the crawler robot: "This is the giant's cave?" Almost a meter high steps, what kind of creature is this for? ”

Song Zixiao had already returned to his seat and put on his combat helmet, his tone faintly revealed a hint of nervousness, obviously this strange staircase no matter what it was, it could no longer be explained by the magic of nature: "To control the robot to move downward, we need more details to report this discovery to the headquarters." ”

"Roger, I've taken over manually and started entering the hole." Maybe the entrance to the cave in front of him was a little weird, or maybe it was infected by Song Zixiao's tone, Wang Xiaoshi couldn't help but sit up straight and became nervous.

Crawler robots are highly adaptable to complex terrain, and it is somewhat difficult to travel on steps close to one meter high, but it is not impossible to achieve.

Soon the footage began to shake up and down dramatically, proving that the crawler robot was moving forward. The light in the square cave is also extremely unscientific, according to the reason, with the downward angle of the slope inside the cave, even if it is a strong snowstorm outside, such a huge cave entrance can be seen at least tens of meters. However, the crawler robot's camera only floated up and down a few times, and it didn't climb a few steps down before it fell into darkness, and the infrared function was automatically turned on again.

Wang Xiaoshi's lips moved, but remembering what Song Zixiao said about the first law of the interstellar world, he finally did not speak, and silently continued to control the crawler robot forward.

"Stop!" Gao Ji suddenly said loudly.

"What's wrong?" Song Zixiao asked.

"Don't you think this image is a little weird?" Gao Ji replied.

The five of them had already put on VR battle helmets, observing the 3D images transmitted back by the crawler robot. Hearing Gao Ji's reminder, they carefully analyzed the picture in front of them at this moment.

Wang Xiaoshi adjusted the crawler robot to a relatively stable posture and stopped moving forward. There didn't seem to be anything special about the picture in front of me, it was gray except for the huge steps that went down in front of me......

Wait, only what order? Wang Xiaoshi suddenly gasped, he had been focusing his attention on the front just now, but at this time, when he looked into the distance, it was a mass of nothingness......

"It's ...... Illusion? Cao Xiaoke stammered.

"No, the illusion is the result of a disturbed brain, and what we see now is the real image transmitted back by the machine." Gao Ji said.

"It would be nice to have a sonar system for advanced robots......" Luo Wenjun muttered.

"Boss, what now? A few more steps forward? Wang Xiaoshi asked.

"Well, stop one step at a time, be careful." Song Zixiao replied.

The subsequent progress of the crawler robot did not allow them to discover more, and it was always the steps that lay in front of them, and the void remained not far away. And when they turned their heads to look, the distance they had climbed down was real.

"Luckily, it's not a ghost hitting the wall." Wang Xiaoshi exhaled lightly.

However, before this breath was finished, the crawler robot had already climbed to the next step, and the picture in front of him suddenly changed, and his pupils suddenly shrank to the size of a pintip......

Cao Xiaoke couldn't help but let out a sharp exclamation: "What is the situation!" ”

The alarm of the system sounded immediately.

"Signal Interrupted...... The No. 4 construction robot lost control ......"

"Try to relink...... No signal source ...... found"
