Although it was a little embarrassing, Gu Fan was still very interested in the Fat Fish Robot.
Lu Ya explained to her the structure of the Fat Fish robot in a calm tone.
Before the Great Radiation, humans had already invented various exploration robots. The one in Lu Ya's hand was the latest from the base, specifically designed for the military to explore unknown and dangerous waters. The robot's body was constructed from a Class-A alloy, making it difficult to physically destroy. It also had a coating of pigment that changed with the environment, making it invisible.
"It sounds impressive, but the lake is so vast, how long would it take a robot to complete the survey?"
After Lu Ya finished his introduction, Gu Fan raised some questions.
Lu Ya seemed to smile, but the smile was so fleeting that Gu Fan couldn't catch it in time.
Then, Lu Ya released fourteen more "fat fish" in one breath: "Each robot has a detection diameter of two kilometers. This lake covers an area of approximately six hundred square kilometers. If fifteen robots are launched simultaneously, they will be able to detect the entire water area in two hours without any problems."
Gu Fan: ...
The people on Earth are amazing! Without the divine consciousness of a powerful being, they have invented similar technology!
Lu Ya set up the signal connection between each robot and the large-screen tablet, and asked Gu Fan to wait there. He flew half a circle along the shore and put the fat fish robots into the water one after another according to the detection distance. The fat fish, which were black and white on the outside, changed color rapidly once they entered the water, almost blending into the water.
Gu Fan was even more surprised.
Lu Ya returned to the chair under the shade of the tree, and Gu Fan automatically gave the chair to him.
Lu Ya pressed a button on the screen, and the next moment, fifteen small video frames appeared on the screen, playing the panoramic detection images transmitted by Fat Fish.
Gu Fan bent over and stood behind him, selecting a video frame to watch. The fat fish moved almost flat on the lakebed, detecting the aquatic plants and strange fish swimming around. If the strange fish appeared, the corresponding species name and rank would appear above its head. If it wasn't already recorded, a question mark would appear above it.
This is amazing. A dead piece of technology can actually make such a precise, complex and comprehensive analysis.
"Why didn't you mark the plants?" Gu Fan quickly discovered a problem.
Lu Ya: "Most plants are not aggressive. The base's current research is mainly focused on eliminating monsters. In the future, when monsters no longer pose a threat to humans, we can begin systematic research on new plants."
Gu Fan frowned: "How can you make medicine without understanding plants?"
Lu Ya: "Biopharmaceuticals cannot be explained in a few words. When we get back to the base, I'll take you to visit the research lab where there are professional professors."
Biopharmaceuticals? Gu Fan didn’t know much about it, but that didn’t matter. She just knew how valuable these plants were.
The flesh-growing and blood-replenishing pill is a good thing. If she can get the Qinglin grass on this trip and cultivate it in batches after returning to the base, she will be more confident of surviving on Earth.
Ignoring the low-level monsters that kept popping up, Gu Fan concentrated on observing the plants at the bottom of the lake, fearing that he would miss a single green lin grass.
She stared intently and didn't realize that her face was too close to Lu Ya.
The faint fishy smell of the water could not completely cover up the fragrance on her body.
Lu Ya glanced at her, put out a set of tables and chairs, and placed the tablet on the table.
Gu Fan immediately pulled a chair and sat at the table, and of course did not forget to leave a seat for Lu Ya.
Lu Ya did not go over, but looked at the vast lake, while being alert to his surroundings.
The fat fish were moving at a decent speed. After nearly an hour, they had already completed their exploration of the waters around the east bank of the lake and were gradually approaching the center of the lake.
Lu Ya finally sat down next to Gu Fan and enlarged the four images in the middle. The detection range of these four robots covered the waters within a radius of four kilometers with the center of the lake as the midpoint.
Two people divided the work and each observed two.
There were fewer and fewer low-level fish monsters in the picture, Gu Fan's heart beat faster, and he had a bad premonition.
"Qinglin Grass." Lu Ya suddenly said, pointing his finger at a place.
Gu Fan immediately looked over and saw a cluster of green lin grass with leaves floating gently in the water.
Just as a look of joy crossed her face, a dark shadow suddenly swept across the camera lens, causing the water to tremble. With the sound of metal being smashed, the transmitted image instantly went black! The undercurrent's impact caused the images of the other three robots to shake violently. However, when the lake bottom returned to calm, the three robots returned to their original trajectory and continued their exploration steadily forward.
Only the black one never got through again.
That one is also the one closest to the center of the lake.
"Did you see clearly what that was?" Gu Fan looked at the lake worriedly.
Lu Ya enlarged the black video to fill the entire screen and clicked on the replay. When a black shadow appeared from a distance, Lu Ya paused the playback, switched to slow motion mode and continued.
The black shadow came closer and closer, and the picture became clearer and clearer. It seemed that a snake's tail suddenly emerged from a lake stone cave. The snake body, which was more than one meter in diameter, gradually became thinner. The snake's body was covered with metal scales, and the tip of the tail was completely metalized. It was like an iron whip, hitting the fat fish robot accurately. At this point, the picture turned black.
Poor fat fish robot, before being destroyed, it dutifully marked the snake's body: ?, S-rank.
The only monster that can destroy an A-level defense robot with pure physical attacks is an S-level monster or even higher.
An S-level monster whose entire appearance is not visible except for its tail.
"This monster doesn't seem to have noticed the other robots. Let's leave immediately after the other robots have finished their exploration."
Gu Fan tilted his head to discuss with Lu Ya, what is Qinglin grass? In front of life, Qinglin grass is worthless.
Lu Ya said nothing and called up other pictures.
An hour later, Lu Ya was going to retrieve the fourteen robots that had successfully completed their mission.
Gu Fan nervously grabbed his arm and said, "Let's walk around it. Don't disturb the snake. It might have been asleep when we first arrived and didn't hear the engine noise. Now it's awake. If we fly again, what if it attacks us?"
She was really scared, her face was pale and her hands were shaking.
Lu Ya: "Too slow."
After saying that, he suddenly put his arms around Gu Fan's waist and flew along the lake with her!
The engine noise of his S-class armor and boots was lower than that of his A-class ones. Despite this, Gu Fan was still extremely panicked and didn't even have the mood to care about Lu Ya's rash actions. He clung to him tightly with both hands and tilted his head to stare at the center of the lake.
Each Fat Fish robot automatically stopped on the shore. As long as Lu Ya flew close enough, he could just put the robot into space out of thin air without having to land.
Just like that, in just a few minutes, Lu Ya successfully recovered thirteen robots.
There was only one left, and Gu Fan whispered in his ear, "After you collect this one, just fly away."
However, it turned out that she could not command Lu Ya at all. Not only did Lu Ya not fly away, he also took her and landed in front of the fourteenth fat fish.
Gu Fan was both anxious and angry. If there weren't so many high-level monsters in the Fairy Peak area, she would definitely have left Lu Ya behind and left by herself.
"what you do?"
Seeing Lu Ya take out another robot and tablet and skillfully connect the signal, Gu Fan asked in disbelief.
Lu Ya placed the two robots into the water and whispered, "I'm responsible for your safety and won't engage it rashly. But since we're here, I have to know its full appearance."
Gu Fan was so anxious that he wanted to snatch the robot back, but was stopped by Lu Ya.
Gu Fan glared at him: "You keep disturbing it, what if it chases you out?"
The monster has a strong sense of territory. It doesn't take a fat fish robot seriously, but if another one comes, how can it not guess that there is an enemy outside?
Lu Ya looked at her, his eyes as clear and pure as a child's, anger and fear were clearly visible.
"If it chases you out, I'll take you away immediately. There's a distance difference, so escaping won't be a problem."
Gu Fan was almost getting angry, but the two fat fish robots had already been launched into the water, and Lu Ya was a dictatorial person. What was the point of her being anxious?
She could only stay by Lu Ya's side, ready to activate her combat boots and fly away at any time.
On the flatscreen, two Fat Fish robots advanced forward and backward, maintaining a distance. One served as bait, the other awaiting the capture of higher-level monsters. As the first Fat Fish approached the lakestone cavern where the snake's tail had appeared, Lu Ya pressed a button on the screen. A red beam suddenly emanated from the head of the invisible Fat Fish, which then repeatedly swung around the cavern.
Gu Fan: ...
This is a blatant provocation!
The lake water was shaking, blowing up the mud and sand at the bottom of the lake and blurring the camera. I could vaguely see a huge creature slowly emerging from the cave.
The Fat Fish Robot stopped its provocation.
This time the monster did not attack directly, as if it had developed some interest in the fat fish robot. When the mud and sand sank back to the bottom of the water and the vision became clear, the huge monster at the bottom of the lake finally revealed its full appearance.
It was a two-meter-thick black snake, its massive head like a small mountain, its dark green triangular eyes fixed on the Fat Fish robot. Most of its body was still coiled, stacked in circles around the cave's exit.
Lu Ya touched the screen.
The motionless Fat Fish Robot shot red light at the black snake again.
The black snake mistook the red light for an attack and quickly dodged it. At the same time, it opened its mouth and spit out an ice spike at the robot.
The Fat Fish robot was destroyed on the spot.
The black snake finally spread its body and swam around the robot wreckage at a speed that made Lu Ya frown.
The black snake's triangular eyes changed color as it suddenly attacked the second fat fish, which was still a kilometer away, and then jumped out of the water.
The sound of splashing water shocked Gu Fan so much that he turned around and ran away.
Lu Ya put away the tablet, caught up with her, grabbed her arm and flew back the way he came at the maximum speed his S-class combat boots could reach.
Only then did Gu Fan muster the courage to look back.
The black snake was chasing after us through the water. When it reached the shore, its entire body was finally exposed. It was over a hundred meters long!
The black snake moved forward rapidly, spitting out a piece of ice spike in the direction of the two people.
Lu Ya grabbed Gu Fan and lifted him up to avoid this wave of attacks.
If he were alone, he would go back and fight the black snake to test its defense, but he promised Gu Fan that he would ensure her safety first.
The black snake's speed in the water far exceeded the two men's flying speed, but it was slightly slower when it reached the shore. It chased them all the way to the outer mountainous area of this area. Only when Gu Fan silently prayed did the black snake stop, hissing angrily. Its red triangular eyes were like two huge lanterns hanging above the forest, and were deeply imprinted in Gu Fan's mind.
The author has something to say:
Black Snake: If you come again, I will eat you!
Fanfan: I dare not, I dare not, I will never dare to do that again.
