On the other side, Proxima b surface, a closed nursing home.

When he first arrived on the ground, Proxima Centauri's powerful gravity almost crushed the old chairman of the parliament.

Life in a long-term zero-gravity environment is the most unfriendly for the elderly.

After a day of adaptation, the old councillor recovered a little ability to move.

Of course, most of the time, they still move with electric wheelchairs and several robotic arms.

Although there is some mobility difficulties, the old president of the council is not disgusted with his current life.

In the enclosed nursing home, he was basking in a faint sunbath from Proxima Centauri through the glass curtain wall, feeling the gravity pulling himself to the ground...

He seemed to have regained the feeling on earth.

Outside the glass curtain wall are some small shrub-like plants with purple-black leaves.

Even occasionally, he could see some strange-shaped insects crawling around the glass curtain wall.

These alien creatures seem to be curious about this strange building.

In the distance, several tall electromagnetic cannons stand.

That is the protective device responsible for protecting the nursing home.

Zero's holographic image stood beside the curtain wall, staring at the old man silently, waiting for his next order.

The old president of parliament sat in a wheelchair and narrowed his eyes slightly to look at the sky.

Five long flight trajectories appeared in the orange-yellow sky.

A little clear in his eyes.

It seems that the surface laboratory has been completed.

I guess Professor Lu is going to start busy again?

He slowly closed his eyes, felt the warmth from Proxima Centre, and sighed silently in his heart.

Hopefully, everything goes well.

Hope that human civilization will prosper forever.

...

The next day.

Photon Computer Laboratory.

After a night of rest, most researchers adapted to the gravity environment of Proxima b.

Although some intense physical exercises cannot be performed, normal movements are no longer hindered.

then.

The photonic computer research and development project has officially started.

...

In the laboratory, several researchers stood in front of a huge holographic projection.

"Professor, the new material has been successfully synthesized!"

"There is no error in the information about Proxima Centar civilization!"

A voice full of surprise rang out in the quiet laboratory.

Lu Yongchang's expression moved slightly, and he immediately stepped apart and rushed towards the direction where the sound came.

Mo Zeyang, who was standing beside him, was stunned for half a second, and immediately followed Lu Yongchang's footsteps.

"Have the nature test passed?"

While walking, he asked his own question.

"Not yet." The researcher shook his head.

Lu Yongchang did not continue to ask, speeding up his pace.

The distance between the laboratory bench is not far.

If it were on [Earth], Lu Yongchang believed that he could reach his destination within ten seconds.

But now...

More than twenty seconds later, he successfully dragged his heavy body to the experimental bench.

A piece of black substance lies quietly on the laboratory bench.

The object is rectangular.

"Yongchang."

Mo Zeyang, who was following him, came to the experimental bench with a heavy breath.

He glanced at the inconspicuous rectangular substance on the experimental bench, and a little puzzled appeared in his eyes.

"Is this the key material for photon computers?"

Lu Yongchang stared at the black square in front of him and nodded silently.

"good."

"In the data, this new material has a magical feature."

"In Proxima Centauri civilization, this material is called Stree."

“I prefer to call it semi-transparent.”

"As for the reason...it's very similar properties to semiconductors."

"It's just that the object of action is not electrons, but photons."

Mo Zeyang looked at Lu Yongchang with a puzzled look on his face.

The deciphering and interpreting Proxima Centar civilization materials has always been carried out by Lu Yongchang.

That's why, at present, he is the only one in the laboratory to know the properties of this so-called semi-transparent body.

The corners of Lu Yongchang's mouth gradually rose.

A mysterious smile appeared on his face.

"Come on, look at it in the light."

While speaking, Lu Yongchang reached out to pick up the black cuboid on the laboratory bench and handed it to Mo Zeyang.

Mo Zeyang hesitated for a moment and carefully reached out to take the rectangle.

He then raised it over his head and observed it towards the lights on the ceiling.

It was pitch black.

In his sight, this cuboid is like a small black hole, allowing no light to pass through it.

"This..." Mo Zeyang turned his head and turned his puzzled eyes to Lu Yongchang.

Lu Yongchang leaned over and glanced at the black rectangle from Mo Zeyang's angle.

"Look in a different direction."

His smile became more and more obvious, and he said softly.

Mo Zeyang: "???"

Although he was full of doubts, he turned the black cuboid in his hand in a direction according to Lu Yongchang's statement.

This time, when he looked up at the so-called black cuboid, a magical phenomenon happened!

The light shone through the black rectangle and shone on Mo Zeyang's face.

Perhaps because of the low light transmission, the originally bright light seemed a little dim in Mo Zeyang's eyes.

"this!!"

He narrowed his eyes slightly and adjusted the direction of the rectangle back and forth towards the light.

After several tests, he swallowed hard and looked at Lu Yongchang, who was smiling beside him incredibly.

"This is a one-way light transmitting body?"

Lu Yongchang nodded with satisfaction.

"Remember what I just said? It's similar to a semiconductor."

"The rectification effect of semiconductors is also reflected in it."

"We all know that the conductivity of a semiconductor is related to the direction of the applied electric field. If a forward voltage is applied at both ends, the current can pass smoothly, but if a reverse voltage is applied, it is not conductive."

"This semi-transparent material is similar to it, except that the voltage becomes photovoltaic and the electrons are replaced with photons."

Mo Zeyang's breathing gradually became rapid.

"This is the perfect electronic switch!"
