In March and April every year, the warm air from the ocean lands and arrives in the southeast of our country to meet with the cold air here to form a front, forming clouds to rain, which is often called spring rain.

Today is the same, the sun was shining at noon, but at two o'clock in the afternoon, it suddenly started to rain lightly, and it couldn't stop.

Outside the community opposite Jiming Temple, a gray Kia Sportage was quietly parked in front of the convenience store, the rain clouded the windshield, and through the dark black side window glass, you could vaguely see two men sitting inside.

"How long have you been in?"

"It's been almost two hours!"

"Would you like to go in and have a look?"

“...... Let's wait. ”

After another 20 minutes or so, a black Audi drove out of the neighborhood.

"It's out. ”

After the Audi drove away, the man sitting in the passenger seat took out his mobile phone, dialed a number and said, "The target has left the community, what now?"

"Well... Good ......"

"What did the boss say?"

"Someone went to follow, and the boss asked us to go up and have a look. ”

The car started and slowly drove into the unguarded community.

After the car turned around the neighborhood a few times, it heard a place where there were no cameras, the door opened, and two ordinary-looking men in leather jackets got out of the car.

I entered the building with a familiar way, and then went upstairs through the safe passage.

Three minutes later, the fire door on the 7th floor was pulled open from the outside, and a sneaky man wearing a peaked cap stuck his head out from behind the door, listened quietly for a while, and then walked out without any movement.

"Which one?"

“709.”

"There is a camera ......" The man in the cap was just about to turn the corner, when he noticed the white light shining on the ground by the LED light cluster next to the high-definition camera, and shrank back in fright.

"The boss doesn't let the grass startle the snake, what can I do?"

The other thought about it, quickly noticed, took out a strong flashlight from his pocket, turned it on, adjusted the angle, and walked out.

The bright light of the flashlight interfered with the camera's capture, and the surveillance was white and there was no idea what was happening.

The two leather-clad men walked to the blind spot under the camera in such a blatant manner, and then tinkered with the gate for a while.

"Click~" The anti-theft door lock opened in response, and the two people immediately flashed into the room.

There was nothing in the room except a pile full of empty boxes, and the two men took out their phones to take a few pictures before leaving.

......

In addition to tracking like this, there are many things that can be done during the rainy season, such as sleeping soundly, listening to the rain, or thinking about certain things.

In Jinshi University, the senior students are busy with their work after graduation, and even if it rains, they are still busy submitting resumes and running the talent market;

At this time, in Building 4 of the women's dormitory, Song Yunxiang, who was wearing rimless glasses, suddenly got tired of it for no reason after completing a few reasoning questions.

He took off the rimless glasses on the bridge of his nose and put them on his textbook, reached out and rubbed the bridge of his nose, got up and walked to the back window.

Outside, the sound of rain is ticking, and the Four Seasons Garden in the distance is shrouded in smoke and rain, which looks picturesque. It was at this time that she felt as if she had forgotten something.

Song Yunxiang's memory has always been very good, so this feeling of "forgetting" made her very uncomfortable, and she thought about it, what did she forget?

I took out my mobile phone from my pocket and looked through it for a while, and there were some apps related to mathematics, Go, Chinese painting, classical music, etc., and I turned two pages and saw a number of unread messages that I hadn't logged in for a long time.

Click on it to see, most of them are push messages, and at the bottom there is a person with the note "weirdo" who sent a message, the time is February.

Seeing this name that was about to fade away, the memory suddenly emerged, and there was a look of sudden realization on his face.

"Ahem, cough, cough......" coughed a few times, and Song Yunxiang clicked on the message and read it carefully.

Inside are some explanations of photonics by the "weirdos".

With her knowledge reserves, of course, she can see that this explanation is purely fabricated, but the fabrication is also based on evidence, and ordinary people really can't tell whether it is true or false, and many of the ideas in it are quite novel, not complete nonsense.

Thinking of something, Song Yunxiang searched on the Internet, and when she saw the ATOLEDA technology released by Tianyi, Song Yunxiang couldn't hide the surprise in her eyes.

She was really amazed. Countless foreign scientists and researchers have been studying the current difference and brightness difference of AMOLED non-uniformity day and night, but she never thought that it would be the first to be made in China, and it was the weird company.

I don't know why, Song Yunxiang has an intuition that this technique must have come from the hands of that weirder.

Song Yunxiang held her mobile phone and edited: "How do you solve the problem of threshold voltage and mobility? How do you allocate the electricity of NOR compensation? Chinese standard substrate is in ......"

may have been accustomed to this way of questioning, Song Yunxiang didn't feel that there was anything wrong at all, threw the question over, and then stood there waiting with a mobile phone.

After about five minutes, the information came, Song Yunxiang looked at it, and then the corners of her mouth curled.

The message is just three words: I don't know!

After thinking about it, Song Yunxiang edited again: "I have recently been studying the photonic crystals of BandGap produced by light in the visible range, do you have any good suggestions?"

As soon as the message was sent, a call immediately came from there, and a hint of a smile appeared in Song Yunxiang's eyes that were beyond her age, which was a different kind of pride.

As soon as the phone was connected, Han Yi's laughter came from inside, "Are you really studying photonic crystals?"

"I don't know!" Song Yunxiang said succinctly.

"Tut-tut, I haven't seen Song Dacai for many days, you have learned badly, and you will actually take our army. ”

Song Yunxiang pursed her lips and snickered, and only said when she asked again on the other side: "At present, the main direction of attack is the light path. Light is forbidden to appear in the bandgap of the photonic crystal, based on this ......"

Han Yi on the other end of the phone listened quietly, and the shock in his heart jumped on his face.

If you want to realize the hologram, the optical path is the foundation, if this step is not compacted, the hologram is a castle in the air, and the huge amount of information processing is not at all what the current optical fiber can load.

Just like a cell phone base station, there is no signal for you to make a fart call.

Today, the optical path is just an idea, and it is unlikely that it will be industrialized in the next ten years, but he can't wait that long, and holograms must be on the agenda in five years.

But who will solve the problem of optical pathways? It is not very realistic to rely on him alone.

But the construction of optical channels is a long-term thing, and if you don't start working now, what an embarrassing thing it is to wait for the real holographic image to be developed but there is no network?

Today, Song Yunxiang's words woke up Han Yi at once.

Since Song Yunxiang focuses on the light path, why don't you give her a ride?
