As soon as he came to the underground laboratory, he saw a bottomless tunnel, and Lin Feng found that the road surface of the tunnel was a little different, paved with a layer of special materials, which looked like a layer of white cloth was laid on the ground, and the fine lines were clearly visible.

"What's going on on this pavement?"

"This kind of pavement is called high-speed magnetic pavement, which is a new material. "This is inspired by a kind of magnetic worm on the bottom of the sea. This kind of magnetic worm is also a newly discovered creature, and when Professor Qi gave me the information, I thought about whether I could use it, and it was really successful. ”

Lin Feng touched her hair appreciatively, regardless of whether this kind of technology exists in aliens or not, but this time at least he did not learn or learn from others, but developed it himself.

"What's the use of this pavement?"

"I'll show you an experiment first. ”

As he spoke, the two of them walked into the laboratory next to them, and there was also the same pavement material on a table, and two conductive shelves were sandwiched on either side of the table.

Sima Lili put a magnet in the middle of the table, then turned on the power, and as the current slowly increased, the magnet actually floated slowly.

Lin Feng knew that this was the principle of mutual repulsion of magnetic fields of the same level, but to make such a large area of the table produce such a strong magnetic field, it would take a huge amount of current.

But he saw from the ammeter that the current is not very large.

Sima Lili smiled and asked, "Do you think you have violated the laws of physics?"

"It's kind of weird. ”

"That's because you don't really understand the properties of this material," Sima Lili opened the schematic diagram on the computer, "The biggest feature of this material is that when there is an electric current passing through, it will generate a corresponding strong magnetic field near the strong magnetic field.

"For example, now, only a small area near the magnet has a large current passing through, but not elsewhere, it is selective, so we also call it a smart magnetic pavement. ”

Lin Feng felt that nature was too mysterious, and what human beings couldn't imagine before, had already been revealed through all things in heaven and earth, just waiting for a pair of eyes to discover.

Sima Lili continued: "We use this principle to connect the positive and negative poles of the battery to the front and rear wheels of the car, which is equivalent to adding voltage to the magnetic circuit, and once the road surface senses the magnetic field of our engine, it will generate a corresponding strong magnetic field to lift the body up. This is more energy-efficient than using geomagnetic fields, and it is more stable and reliable. ”

Knowing the principle of this special pavement, Lin Feng couldn't wait to try it.

There are still four people in the car, and after Lin Feng turns on the engine, the intelligent system begins to prompt: "Only magnetic road surface is detected, do you turn on the high-speed mode?"

"On. ”

"The high-speed mode is on, and the whole time is autonomous, please set the destination. ”

"It's for safety," explains Sima Lili, "after all, at super high speeds, a person's reflexes can't control the vehicle." ”

Lin Feng nodded, it was true, even the most experienced racers did not dare to guarantee that they would not make a mistake in driving.

Set the key points and cover the whole journey for 50 kilometers.

"Let's go. ”

Huh-

The car accelerates to 400 km/h in 10 seconds, but in high-speed mode, this is not the limit, and the speedometer hands are still deflecting upwards.

500...... 700...... 900......

In the end, the pointer was firmly fixed at 1,000 kilometers, and Lin Feng looked at the time, and it only took 30 seconds in total, and nearly a quarter of the 50 kilometers of tunnel had passed.

"Is this the fastest speed?" Lin Feng asked curiously, because he saw that the maximum scale of the speedometer was far more than 1000.

"The current theoretical maximum speed of the engine is 5,000 kilometers per hour, but it can only be maintained within 1,000 to achieve the highest safety factor. ”

With a speed of 5,000 kilometers per hour, isn't it 1.5 times faster than a high-speed train? In the future, as long as a magnetic highway is built, it will only take an hour to cross the whole of China.

And she is also talking about the current engine, which means that if the engine is enhanced, it is possible to achieve faster speeds.

It is also natural to think about it, Shenxiang can reach Mach 40 and can directly get rid of the earth's gravity and fly into space, relying on pure aerodynamic power.

The high-end civilizations in the universe have used the magnetic field force to the extreme, and from now on, the laboratory can be regarded as touching the threshold.

As long as they continue to study, Lin Feng believes that one day, they will be able to reach Mach 40.

As he spoke, the car had begun to slow down, and it only took 3 minutes and 30 seconds to accelerate and decelerate the 50-kilometer journey.

At the end of the tunnel, he had already left the ground and came to an open field, where Li Guangping and dozens of people were waiting.

"Boss, don't blame me for being rude this time," Li Guangping said with a grin, "This is the boss's order, this is the weight that can destroy a tank, and I definitely can't afford to pay for it if it is blown up." ”

Saying that, he had a few bombs installed on the car, and then everyone evacuated to a safe place and detonated.

Boom –

With the sound of violent explosions, the car was drowned in a thick black smoke, but the imaginary scene of the car flying did not appear, let alone any stump fragments flew out.

After the smoke cleared, the white car was still parked quietly, not even the glass was damaged.

Li Guangping's eyes were about to pop out, and he knew how much explosives they used, but this car even had a good reflector, which made him feel that he had been greatly hit.

Soon the vehicle was rigorously inspected, and the results were as expected, except for the dust sticking to the surface, there was not a trace of damage to the shell and internal structure.

"The sound insulation effect is good, the maximum noise in the car is 95 decibels, which is equivalent to a child screaming, which is within the tolerable range. ”

Sima Lili said to Li Guangping again: "You continue." ”

This time, Li Guangping asked people to bring out two flamethrowers and burn them violently at the car.

"The outside temperature is 1200 degrees, and the maximum temperature inside the car is 33 degrees, and it seems that the insulation effect is also good. ”

The data was quickly detected, and Lin Feng felt that even if the car's defense could not resist nuclear bombs, it was probably about the same. As an ordinary civilian vehicle, what else can it do with such performance?

Li Guangping was a little unconvinced, he had overturned a few tanks before, but now he couldn't take a small car.

"Hang me!"

The car was hoisted up 30 meters into the air and then thrown sideways.

Bang –

After landing, the car bounced on the solid cement floor, Li Guangping hurriedly went up to check, and found that the body was not deformed at all, and even the reflector was just taken back and attached to the body.

Li Guangping scratched his head: "Sister Ni, this thing can be used as a tank when it is loaded with a cannon!"
