One after another, everyone gathered in the warehouse. Each of them is looking for what they need, there is no sadness of parting, no pre-war mobilization, and no grandiose rhetoric. Everyone chose to leave this base camp for a better survival and for the hope of mankind.

"Zhong, you stay and guard our base camp and guard our two unborn children."

"I won't stay, Ray, Joan stay, they're better able to protect this place than I do. Rose, Jie stays here to wait for the birth of the child, and also to guard our base camp. In groups of three, the rest of the people followed me around to have a look. ”

"Okay, robots one and two stay in Lava Village, and you can take them with you three and four. It's not selfishness, it's that the place you go to is not a lava vent, and the robots are two rays of light that cooperate with each other, and if they are separated, they lose their greatest role. Rose said.

"Don't worry, Rose, we're not going to the lava eruption. Finding supply points is the goal of our group. The telegram said.

"We couldn't see the lava at all, so the three of us went looking for soil and conditions to plant. But we're going to bring a road-building robot with us. ”

"Water, clouds, fog, it's a must, each team brings a road-building robot and excavates lava to make a way when necessary."

"There are also medical robots, which have also been repaired, and the energy gems have also been divided equally, so they all have an extra security guarantee."

"I bring enough food for a week, and I try to return to the base camp to replenish it at any time."

"We will return seven days. In the past, we were the appreciators and pleasure people of the earth, and now we are the pioneers and strugglers of the earth. Have lunch and go! ”

In the afternoon, the nineteen people were divided into five groups, Ray, Joan, and two pregnant women, Rose and Jie, who stayed at the base camp. The three-person team of electricity went to the supply point, the three-person team of water went to find a place to plant, and the three-person team of trees did not have a clear goal, but also went out to find hope. Zhong and the others probed around the lava village. The road-building robots also followed each team with heavy loads, two robots that emitted white light stayed in Lava Village, and two robots that emitted orange and yellow light and red light followed Zhong's group. The three groups of electricity, water, and trees all walked on the metallic path at the entrance of the village, and then separated on the main road of the ring and went in different directions. Zhong and the rest of the group began to climb the lava hills. Fortunately, the time on the robot is set by the clock, and the other three groups can only rely on sunrise and sunset to calculate the time.

The hill around the lava village was the most metallized, and they climbed a small hill with difficulty, and looked into the distance, which was no longer flat, and the metal bugs that emerged looked like things planted on the lava, with black and shiny bulges and large round bumps, let's call them heads. The raised metal skull was stiff, and the liquid inside was petrified. The road gradually got better, and everyone jumped and walked among the metal objects as if they were crossing obstacles.

"Zhong, why is it that the farther away from Lava Village, the fewer these metal bugs will come out."

"It's the oscillation of the sound waves, and the lava village is an amplified body, where the most metal bugs come out. The shock and bugs here have just reached saturation, and all the drills have been hardened, and I think the general sound waves can't reach the ground, otherwise it will be a failure of the ring height. ”

"Zhong, what you said makes sense, hey, it seems that there is all lava in front of you, and there are fewer metal bugs." A few more people climbed over a lava hill and looked down. There were almost no bumps visible underneath, and the feet gradually softened, leaving footprints and two traces of the robot when I walked over. The speed of the jump is naturally slow.

At night, several people chose a flat place to set up a tent, and in order to safely start the orange-yellow No. 3 robot, the entire temporary camp was instantly shrouded in a hazy yellow halo.

"Bell, we don't know the role of this light yet, so it's supposed to be used for lighting."

"It's a waste of resources, so let's test the effect of this light alone."

"I didn't feel the lava erupting all day, and I couldn't hear the noise. I don't think there will be any metal bugs coming out of the ground. ”

"We traveled ten kilometers away, and even if it was a lava eruption, it weakened when it came here, and not feeling it doesn't mean that the lava didn't erupt. I remember a while ago, the howling and jumping of trees could summon bugs. ”

"The metal bugs in the shallow layer of lava shouldn't be summoned by us, I'm not used to walking now, jumping is the way to walk."

"Don't be a crow's mouth, it's not fun for the worms to come out."

"Even if there are metal bugs, it won't be more, after all, the sound waves underground are the most effective way to repel bugs."

"Yes, the lava village is the center of the sound waves, you say, when our ancestors built the lava village, they must not have thought of this, otherwise, there would not be a hundred years later."

"Isn't science and technology all demonstrated in practice again and again?"

"Failure is the only way to succeed. Listen, what's the sound? A few people were resting while talking, and suddenly the night wind was mixed with the sound of the swaying rope, and if you didn't listen carefully, you really couldn't hear it.

"Don't scare yourself, it's just the sound of the night wind, or something that blocks the echo that comes out."

"What kind of obstruction, can you find any other shelter here besides the lava hills?"

"I can't really find it, but it's louder. Oops, it's the sound coming from underground. ”

A few people walked out of the tent, and they were immediately surrounded by the cold, and the cold wind cut like a blade, penetrating the cotton clothes and making people's flesh and skin hurt. It's cold! Outside, there was still a flat lava mass, high like a hill, small like a bag of dirt, and the pimples were like scabies on the earth.

"Zhong, why do you feel that those hills are so tall?"

"yes, it's bigger than when we got into the tent."

"It's strange that when we didn't set up our tents, we were in the wilderness, so why was it so cold. It's only been an hour since I entered the tent, and how did it become irresistibly cold outside? ”

A few people spoke, and the orange-yellow light of the robot kept scanning in the moonlight. The mound in the field of vision grew larger and larger, and the surface was undulating.

"It's metal bugs coming out, right?"

"We didn't make it by jumping, did we?"

"What I don't see is a metal bug, why hasn't a single one popped up after ringing for so long?"

"It's that the bugs aren't big enough to get out of the ground."

"The naïve inference is that even if the bugs are small and numerous, otherwise the lava surface will not fluctuate."

"Then there was something that held them back and couldn't get out, and that caused the undulating movement of the lava surface."

"Robot's orange ray!" Several people thought of the crux of the matter together.

Several people looked into the distance in the cold and reasoned in confusion. Suddenly, there was movement in the tent, and the sound of the rope was very loud and strange. Several people hurriedly lifted the cotton curtain of the tent, and were stunned at a glance. The inside of the tent was full of rolling metal bugs, the size of a man's finger, but there were too many. As soon as the cotton curtain of the tent was lifted, the robot's light scanned in, only to see the orange light shining on the surface of the metal bugs, which quickly froze. And there are insects coming out from below, and the entire surface of the insects is undulating like ripples on a horizontal plane.

"Remove the tent!" Zhong decisively decided.

"yes, it's almost a cradle of bugs."

It was easy to build, there was soft lava everywhere, but now it's hard to disassemble first. The ground was much harder, and it was still filled with metal bugs, and it took a lot of effort for everyone to lift the tent. Immediately, an orange-yellow glow covered the surface of the insect. Look at the metal bugs that have been given the shape of the round tent. It's very regular like a platform, and I can't see some irregularities.

"Oh my God, new archaeological discoveries, what's this for?" Knowing that the metal bugs couldn't get out, and the bugs in the tent were all fixed, everyone began to ridicule again with ease.

"Even if it is an archaeological discovery, it should be a few hundred years later. Now it's our tent that hasn't been scanned by the light, and the bugs are gathering together. ”

"Obediently, I originally thought that it would be useful for the four robots to fuse light, but I didn't expect it to be so popular when fighting alone."

"yes, our seniors are so good."

"There are no such robots anymore, and some are the type of nannies who serve humans."

"But it also makes people worry that in a few hundred years, humans will become dolls of robots. I only know to enjoy the waste which does not know the enterprising effort. ”

"Nothing to worry about! Don't forget that robots are also made by humans, not innate, and since humans can make them, can't they control them yet? ”

"It's not unfounded, once the robot has an autonomous consciousness, anything can happen."

"That's all impossible to happen, which family, which person doesn't have a robot service around now, it's not all the programs set by humans, and the execution is also human instructions."

"Oh, too, unless humans are too lazy to do anything."

"I'm too lazy to do anything now, but it's still intact." One man pointed to his head and said.

"Nonsense, if even the mind is lazy, this world and this earth will not belong to human beings."

A few people said and watched, the lava mound in the distance was still moving, and the round platform formed by the tent was also trembling slightly.

"It's not a way to go on like this, the robot's energy is limited, the intensity of light and the coverage area are limited, and once the metal bugs break through the equilibrium, it will not be easy. Turn on the release light of robot four. Zhong pondered.

Soon, the red light of robot No. 4 also began to scan, and the two rays merged into two distinct scans, yellow, orange, orange and red. The mound in the distance stopped moving, and even the circular platform slowly stood still.
