A pile of parts gradually took shape under Su Zhe's dexterous hands, and when his work was almost finished, Jamie and Tom could see its shape. It is shaped like a ball, about the size of a football ball, and the quantum battery and core device are located in the center of the ball, which should be designed for better protection. Its surface is covered by a layer of graphite thin, which has excellent ductility and hardness, which allows it to withstand heavy blows without damage.

In addition, the ball is not completely smooth, and there are some very small holes in its surface, that is, in the graphite-covered area, and it is not known what these holes are used for. Su Zhe completed the last step, then held the ball in his hand and looked at it carefully, and then smiled with satisfaction.

"What is this? Why does it look weird? Su Zhe, you're not going to be bored enough to make a mechanical ball, are you? Tom tilted his head and looked at the ball in Su Zhe's hand and couldn't help but ask, in fact, this is also what Jamie wants to ask, they can't imagine what this thing is for.

"You'll find out later." Su Zhe smiled but didn't reveal the mystery, stood up and greeted his friends: "Go!" ”

"Where are you going?"

"Just come with me."

Holding the ball that had just been completed, Su Zhe took his friends out of the house, and then pushed out a small flying car from the backyard. With the development of the earth's civilization, such a means of transportation has become very common, although Su Zhe's small flying car is not as good as the performance of those luxury flying cars, and it is lacking in speed and sustainability, but it is the most convenient for students, and all ordinary families who have some ability will buy one for their children.

got into the flying car, Su Zhe sat in the driver's seat, he didn't use the automatic driving function of the flying car, and directly opened the navigation and checked the location. Then he drove the flying car to the southwest.

Although it is a small flying car, its speed is not slow, and the speed of 500 kilometers per hour is enough to move in a considerable range. Just over ten minutes later, Su Zhe and the others came to a beach, parked the flying car, and got out of the car. Su Zhe led Jamie and Tom to the beach.

Walking forward a few dozen meters away, it was sea water in the past, and only then did Su Zhe stop.

"Su Zhe......?"

"Don't worry, it'll be right away." Su Zhe turned around and smiled at his friends, and then put the ball in his hand on the soft sand, and then he didn't know what he pressed, the ball actually floated, but its float was a little strange, not floating straight in the air like a flying car. Instead, it floats up against the sand in a small range, and if you don't have a good eye, you can't see clearly.

"Huh!" Tom approached and took a closer look, and there was a look of surprise in his eyes, and then Jamie stared at the floating ball, and he also sighed softly.

Up close, they could see that this float was not really floating, but the surface of the sphere, and the tiny holes near the beach somehow appeared like tiny tentacles. These tentacles are thinner than a human hair and possess great softness and toughness. What's even more surprising is that these tentacles flutter slightly as if they were alive.

"What's the use of that?" Jamie and Tom were surprised, but they were also surprised by the role of these tentacles. In their opinion, Su Zhe's use of these strange tentacles to make the ball float like this has no practical effect at all, and it is better to make a magnetic gravitational controller similar to a speeding car.

Just when they were puzzled about the purpose of this thing, Su Zhe had already opened the portable brain on his wrist and clicked it a few times. Immediately after that, the ball began to move, moving back and forth, left and right, rolling flexibly on the beach according to Su Zhe's manipulation, and the tentacles sticking out of the thin holes covering the surface were like living creatures, moving with the ball without dead ends.

And it moves at a speed though not very fast. But it's perfect, no matter how high or low the beach is, it can cross without obstacles.

"Not bad." Seeing this effect, Su Zhe was a little proud, and then manipulated the ball to move in the direction of the sea, and when the ball moved to the junction of the sea and the beach, a wave just happened, and in the blink of an eye, the ball disappeared in front of their eyes.

Jamie and Tom exclaimed at the same time, but seeing Su Zhe's calm appearance, they couldn't help but ask.

"Come and see." Greeting their friends, Jamie and Tom came to Su Zhe's side left and right, and at this time they saw a three-dimensional image displayed on Su Zhe's portable brain, which was the scenery of the sea, and these scenery were constantly changing.

"This is the ball...... In the sea? Tom asked, stunned.

"Answer correctly, unfortunately there is no reward." Su Zhele joked happily, and continued to manipulate the ball that had entered the sea towards the depths of the ocean. Jamie watched curiously as the images shifted, and asked, "Are you here to explore the ocean?" ”

"Yes and no, it's just one use for it." Su Zhe explained with a smile, at this time, the picture in the image has changed a lot, don't look at the speed of the ball on the beach is not fast, but its speed in the ocean is a little amazing, and from Su Zhe's explanation, those tentacles will be withdrawn once they enter the ocean, in the ocean the ball is relying on the fine pores covered with the surface to move with the principle of water flow and jetting, of course, in the depths of the seabed, in the case of complex terrain, you can also continue to use those tentacles to manipulate the ball.

These are only the motions of the ball, but not the real function of the ball. According to Su Zhe's explanation, this thing is called an all-terrain detector, which can replace humans or even robots for detailed detection in any different environment.

The earth's civilization has developed to the point where the technology for exploration has matured. Even in the universe, relying on the large intelligent brain and professional detection equipment of a spaceship, it is easy to carry out a comprehensive exploration and scanning of a small terrestrial planet. However, it is important to know that this kind of detection and scanning also has a flaw, that is, there is no problem with large-scale detection and scanning, but it is necessary to do detailed detection work, for example, the detection and search in a very small area must rely on robots or human control instruments to carry out.

Su Zhe's all-terrain probe was used to do these things, although the Earth civilization already had something similar, even better than the one he made. But the size of the device, the agility of its movement, and the simplicity of its manipulation make this small ball even better. Jamie and Tom couldn't help but marvel at the constant changes in the three-dimensional image, and as Su Zhe manipulated the small ball even to a depth of thousands of meters under the sea, it was still able to move freely. What's more, Su Zhe was amazed that he could rely on his personal strength to make such a thing.

Unfortunately, due to material and some technical limitations, Su Zhe's all-terrain detector still has a big shortcoming, that is, its control distance is too short. When the ball exceeds the design distance, or is shielded due to the depth of the seawater, it can no longer be detected. But these problems have nothing to do with design, and if Su Zhe had a spaceship-level supply of materials and components, he could have made a finished product that would have carried out a comprehensive and detailed exploration of the ground in low-Earth orbit. If the smart chip is improved, it can even be made to perform detailed detection automatically. Synchronous data transfer to greatly reduce workload.

These are not counted, Su Zhe even has another consideration, that is, to produce such small all-terrain detectors in batches, to detect and deliver them in batches, and then speed up the detection speed through the brain and program settings. In the future, it may even be possible to upgrade it even better, such as adding mining and gathering capabilities. This is not only widely used in detection, but also in exploration and rare material collection.

"You kid. He's a science maniac. Two hours later, when the ball had successfully returned to land from the ocean and down the beach, Tom couldn't help but say something when he saw Su Zhe crouching down and putting it away.

"That's right, science maniac!" Jamie nodded in agreement, and then asked, "That's right, Su Zhe." I'm graduating in half a year, have you thought about what university to go to? ”

"I want to go to the Federal University of Science and Technology." Su Zhe stuffed the ball into his bag and replied.

"I remember the Federal University of Science and Technology in Asia, right? It's a long way off. Jamie wondered: "Union University is also the best university in the Federation, why don't you go to Union University?" ”

"Yes! Why did you go to Asia to go to the Federal University of Science and Technology? Tom asked, too, a little puzzled.

Indeed, as they say, Union University is also one of the best universities in the entire Earth Federation, and its reputation is no less than that of the Federal University of Science and Technology. Even from the perspective of historical depth, the United University, which was formed by the predecessors of Oxford, Cambridge, and Paris before the New Era, has a greater sense of history and connotation. And they have been living in the European region, although now the technology is developed, in terms of transportation, it only takes a short time from Europe to Asia, but after all, in terms of geographical location, the United University is much closer to home, and it is more convenient.

"My mom suggested that I go to the Federal University of Technology, and I myself felt that it would be more appropriate to go to the Federal University of Technology in the direction of my passion." Su Zhe replied like this, hearing him say this, Jamie and Tom immediately closed their mouths, Su Zhe's mother they have all met, and they are not even strangers, because his mother is not only a professor at Union University, but also the principal of the community high school, and whether it is Su Zhe or Jamie or even Tom, the three of them are all her students.

"By the way, Jamie, what about you? What are your plans? ”

Jamie smiled, his chubby face narrowed into slits with a smile: "What else can I do, go to business school, my father is still looking forward to me taking over his class after graduation." ”

"Hehe......." Hearing this answer, Su Zhe and Tom were all happy, of course they knew the situation of Jamie's family, and they also knew that his father had always wanted Jamie to be a successful businessman like him. Especially in recent years, with the gradual expansion of the power of the earth civilization and the acceleration of the exploration and development of the area outside the Oort Nebula, the company of the Jamie family can be said to be thriving, and it is natural for a father who is a businessman to have such thoughts about his son.

"What about you, Tom? Planning to go to military school? ”

"Yes!" Tom nodded seriously, his friends all knew his ideals, to become a soldier, and even to become a member of the space fleet, this was Tom's dream since childhood. But compared with Su Zhe, a science madman, and Jamie, who has a good family background, Tom's grades are just ordinary, and the only thing he can do is good physical fitness and the pursuit of his dreams.

However, the current era is different, and soldiers no longer rely on individual force to fight, and with the development and constant changes of science and technology, except for some special branches of the military, wars in the universe rely more on tactical capabilities and the power of science and technology. Although Tom has always had the idea of going to a military school, and has never given up his ideals and pursuits, he also knows in his heart that it is still unknown whether he can be admitted to the military school, and if he fails to apply for the exam, he really doesn't know how to face ......the cruel reality.

Thinking of this, Tom's expression was a little gloomy, and seeing his expression, both Su Zhe and Jamie comforted at the same time: "You must do it, Tom!" It's just a military school, and a natural soldier like you will definitely be able to get in! Maybe one day you will become the general of the space fleet, and we will still be able to brag with others, look! Does this Admiral Tom know? He's a good friend of ours, and we've grown up together....... ”

Listening to the words of his friends, Tom couldn't help but be happy, the few shadows in his heart just now disappeared in an instant, and the three of them sat side by side on the beach and chatted about their future, looking forward to the upcoming life, in their eyes, the future is beautiful and desirable.

Until the afternoon, the sun was gradually setting in the west, and a red sun had already taken over the water, illuminating the whole ocean beautifully. The three reluctant friends looked at the beautiful scenery of the sunset, got on the flying car, and headed in the direction of home.

After sending Tom and Jamie home first, Su Zhe drove back to his home in a flying car. When the flying car entered the yard and came to a steady stop, he suddenly noticed that there was an inconspicuous-looking flying car in the parking space, but it had a somewhat unique shape.

"...... this?" Su Zhe was stunned, and soon he recognized the origin of this flying car, isn't this a special military flying car? This kind of flying car is only owned by the army, and it cannot be purchased in the outside world at all, and it is not something that ordinary soldiers can drive, you must know that such a special flying car is only used by some high-level officers as a special car, don't look at it as inconspicuous, but Su Zhe, who is familiar with flying cars, knows that its performance is outstanding, and even has an attack ability that ordinary flying cars do not have.

"How can this car be here?" Su Zhe was very curious, in his memory, his family had never had relatives in the military world, and he had never seen his parents have friends in the army, and their family was just ordinary people. (To be continued......)
