"Time is scattered in the flowing water, heading westward without stopping."

“Life is like a small boat, drifting involuntarily in the river of time and space.”

“The greatest gift in the world is that we will meet again.”

Spann stood on the bridge, looking at the dark and mysterious universe through the observation glass, and softly sang the ancient songs of Mayan civilization.

The Tianjue sailed in the deep space, passing through one wormhole after another.

Brother Liu said nothing, his face flickering with light from unknown stars.

Spahn's song celebrates reunion.

But Brother Liu knew that the real world was not so beautiful. After many separations, there was no reunion.

Just like the hundreds of people you pass by every day.

There was an inexplicable gloom in Liu Di's heart.

He slowly raised his head and looked towards the ceiling of the bridge. His sight penetrated through layers of space and he 'saw' a planet tens of millions of kilometers away.

There seemed to be a huge straw inserted on the gray planet, like a coffee ice cream ball with a spoon stuck in it.

"Go out for a walk."

Brother Liu's body dissipated into an electromagnetic wave state and left the Tianjue.

The people on the Tianjue did not notice and headed straight to the west. Even if Brother Liu relied on his mortal body, it would be extremely easy for him to catch up with them.

Liu Di floats in the universe in an invisible form, seemingly above everything.

"The electromagnetic wave state is one of the 12 forms of matter."

"Theoretically, it can reach the speed of light."

"I haven't tried yet. What is it like to reach the speed limit of human cognition?"

Liu Di suddenly accelerated towards the direction of the ice cream ball.

"10% the speed of light."

"30% the speed of light."

“50%.”

“80%.”

"90% the speed of light."

From Liu Di's perspective, no matter how far away an object is, it will be level with his perspective in the next moment, and then be left behind, becoming so tiny that it cannot be detected.

The feeling of 'speed' is becoming increasingly indescribable.

Quick, quick! Everything is fleeting.

Why? Brother Liu asked himself, now is a vacuum state, I am in the form of electromagnetic waves.

Electromagnetic waves and light waves.

Although these two concepts are strictly distinguished by modern science, to some extent, they are both "vibrations of the medium."

Because the distance between air molecules is greater than the molecular diameter, the diffraction distance caused by electromagnetic waves can be ignored, making the speed of electromagnetic waves in the air basically equal to the speed of light.

What's more, it's a vacuum now.

Why can't I reach 100% of the speed of light? "The limit is 90% of the speed of light."

"It's like something is holding us back."

The voice of the demon boy came.

Brother Liu was also thinking to no avail, but it only took a moment.

The 'ice cream ball' appeared in front of Liu Di.

It is a celestial body about five times the size of the Earth, covered by a cream-colored atmosphere.

The 'straw' inserted into the planet is a huge glass tube with a diameter of nearly 100 kilometers and a length of tens of thousands of kilometers, pointing into the universe like Optimus Prime.

Liu Di entered the atmosphere of the planet and his body condensed into a human form.

But the creatures they saw here looked similar to the Kaban scientists. They were short, had gray hair, wore exquisite clothes, and looked like goblins.

At first glance, they appear to be craftsmen with extremely high skills.

"Who are you?"

"Is it an intruder?"

A gray goblin looked at Liu Di in horror, his eyes wide open.

"That's not important."

Brother Liu said lightly.

Then, nearly 100 million gray goblins on the entire planet entered another timeline. Countless Liu brothers appeared in front of them at the same time and explained to each of them.

——"I'm just a traveler passing through with good intentions."

These words were deeply imprinted in the minds of every gray goblin, and in an instant, they let down all their guard.

"Who are you and what are you doing?"

Liu Di asked the goblin in front of him.

"We are the Gear Civilization. My name is Roy."

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

Gray Goblin Roy said modestly: "What we are best at is carving. Our hands can carve the most precise parts in the universe. Even the most powerful computer in the world cannot match our carving accuracy."

Speaking of.

Roy took out a model that was made of aluminum and shaped like an airplane, held it gently in his hand, squinted his eyes to measure the distance, and then threw it into the air.

But I saw the model of the airplane floating in the air, flying farther and farther, flying over the cities on this planet. All the buildings in the city were inlaid with precise gears, and some buildings were even huge gears themselves.

The plane flew farther and farther away until it disappeared without falling.

During the process, Mo Tong analyzed the data of the model.

Precision carving and polishing reduce its air resistance infinitely.

The perfect design allows it to continuously rely on rising air, and it seems to have unlimited power. Assuming there is no physical obstacle, it can fly forever.

“Purely hand-polished, it’s amazing that this level of polishing can be achieved.”

Brother Liu sighed inwardly, the universe is so vast and full of wonders.

Liu Di turned around and looked at the huge straw on the planet, "What is that?"

Roy nodded and said, "That is the super gear accelerator created by hundreds of generations of residents in our gear civilization over a period of 1,200 years."

Liu Di squinted his eyes and saw that the huge glass tube was reflecting dazzling light under the light of the stars.

Inside the glass tube are smart gears one after another, starting from the ground, with the teeth of each adjacent gear meshing perfectly, extending all the way into the universe.

"Gear Speed ​​​​Up Super?"

Brother Liu whispered softly.

This kind of mechanical equipment is very common, such as the gearbox of a car.

When the engine speed remains unchanged, the rotation of the tire can be accelerated or decelerated through the gear set.

The most common one is the reducer.

The high speed of the motor in winches, crane pulleys, etc. is slowed down by gears one by one, generating huge torque.

This is the principle of gear ratio.

The acceleration effect is also easy to understand. A huge gear drives a small gear. When the big gear rotates one circle, the small gear will rotate two, three, or ten circles.

If the diameter of subsequent gears gradually decreases, the speed will increase infinitely.

Liu Di looked at the huge glass pipe.

At the bottom of the pipeline is a huge gear with a diameter of at least 5 kilometers, like a super-large Ferris wheel standing on the ground.

This gear is connected to another gear with a slightly smaller diameter.

One after another, they are located in glass tubes that stretch to the sky.

Just as Liu Di guessed, the gears gradually became smaller.

As Roy said, this is really a super accelerator.

But this obviously does not have the production capacity. What is the purpose of the gear civilization making this thing? But Roy said respectfully: "As you can see, we are determined to break through the law that is listed as a ban in this universe."

"We're going to go through the gear accelerator."

“Breaking the speed of light.”
