All the search finally paid off.

Li Ruina looked at the two machines and said approvingly, "Your method seems to be probably right. These two are the latest research developed by AEF, the light wave sensor and the light wave splitter. ”

"Lightwave sensors and lightwave splitters? What's the use of that? Can you take us out of this labyrinth? Cui Li pushed the square instrument with his hand and asked suspiciously.

The circle around the instrument seemed to be close to the solar panel, and Li Ruina stepped forward and turned on the switch on the instrument, and suddenly the instrument began to unfold outward, and then a display screen was folded in the middle.

"This is a light wave sensor, and this machine can receive light waves from all directions, and then display the results of the light waves on this display through precise analysis." Li Ruina said, shining the flashlight at the machine. I saw a few words suddenly appear on the monitor: "Calculation, please wait." ”

"Wow~ This machine looks very powerful!" Cui Li lifted his glasses, looked at the instrument excitedly, and couldn't help but sigh.

Suddenly, the words on the machine's display disappeared, and then a number "68" appeared.

"As said before. This flashlight is not an ordinary flashlight, and it is also the latest technology researched by AEF. To put it simply, the light waves emitted by this flashlight are very stable, and under normal circumstances, even the reflected light waves do not weaken. Li Ruina took the flashlight from my hand and continued: "For example, if I use this flashlight to shine on a mirror, and the mirror is reflected on this machine, the number on the display screen should still be 68. ”

"You're right, but didn't Lin Yun say it before? When the flashlight light is facing the T-junction, the light will not choose the left or the right by itself, all the light will only shine on the wall, and there is no way to return the light to the original point. Cui Li looked at Li Ruina and said.

"That's true, even if we have a light wave sensor, it's still far from enough, the light can't choose its own route, so the light can't go back to the original point, but have you forgotten the machine you just saw at the T-junction?" Li Ruina pointed to the machine at the T-junction and said.

"Could it be the other machine you just mentioned?" Cui Li suddenly remembered the machine he had just seen.

"That's right, it's the light wave splitter, this machine can divide the received light into several rays and reflect them at a set angle. Take our flashlight as an example, the light wave signal of this flashlight is 68, once it is divided into two light waves through the light wave splitter, the signal of each light wave is 34, and so on, as long as you encounter a light wave splitter, the light wave will be split into two rays. Li Ruina said that the flashlight shone on the light wave splitter at the T-junction, and suddenly the light was split into two and shone straight towards the mirrors at the corners of both sides.

"Looks like we've found a way out! Is there anything I can do to help now? I can't wait to get out. Cui Li was very happy on the side.

"First of all, we need to leave one person here to make sure that the number on the light sensor is close to 68. The rest of the people test all the selected intersections together. By the way, we also need to dim the lights so that it doesn't affect the light wave collection of the light sensor as much as possible. Li Ruina glanced at all of us as she spoke.

"But how do we inform you of the number of the light wave sensor?" Cui Li's question is also what I think.

"It's easy! We can use walkie-talkies, we need to confirm the channel of the line first. Li Ruina turned on the walkie-talkie and said, "Can you hear me?" Can you hear me? ”

"I can hear you. It can be heard. Cui Li's walkie-talkie came from Li Ruina's voice.

September 22, 2021 at 14:10 p.m.

"It seems that all the preparations are almost ready. Let's start with the first T-junction. "I shone the light of the flashlight on the light wave splitter.

Sure enough, as Li Ruina said, the light wave splitter split the received light in two and reflected it in two different directions. Cui Li had dimmed the lights in the maze a lot. At this time, sure enough, several different rays of light hit the light wave sensor, and the display screen on it appeared again, "Counting, please wait." "After a while, another number '66' appeared on the display.

"The surrounding environment, whether the mirror is smooth or not, and many other problems will affect the final number analyzed by the light wave sensor.

"Cui Li, you stay and observe the digital changes on the display screen above the light wave sensor. Then use the walkie-talkie in time to tell us, okay? I glanced at Cui Li and said.

"Of course, when you're all out, you'll tell me the exact route."

Cui Li looked at me and readily agreed.

We started our thoughts with the first right turn, and it didn't take long for us to come across the second light wave splitter, we shone our flashlight, and the walkie-talkie in our hand rang again. "Can you hear me? Can you hear me? ”

"What's wrong? Cui Li? What are the numbers on the display now? I said into the intercom.

"The number on the display is 59! 59！ 59！ Cui Li shouted loudly on the other end of the walkie-talkie.

It seems that we have found part of the right answer. The light waves of the flashlight did not quite return to square one. So, there must be a part of the light waves that have left this labyrinth.

"We've found a fraction of the right route!" Li Ruina concluded.

September 22, 2021 at 15:11 p.m.

We've walked through more than 20 T-junctions, and we feel like we're getting closer to success.

"We should be almost at the exit of the maze, and when the number on the display is 34, it is our last choice in this maze," Li Ruina said earnestly.

September 22, 2021 at 15:51 pm.

"Cui Li, what is the number on the display?" I asked.

“34！ 34!34！ Cui Li's voice was full of indescribable joy.

"In other words, if I choose the other side, it will be the exit of this labyrinth!" My mood at this time is the same as Cui Li's.

We turned a corner along the aisle, and suddenly we saw that the exit was right in front of us, and all the effort was worth it in this moment. Our mood at this time is also indescribably happy.

Seeing that the exit was now in front of us, I had a feeling that all the answers were about to be unfolded in front of us. It's time to wrap up this test!
