It should be around four o'clock, and the flow of people in urban universities is sparse, and many people choose to stay indoors. There is a new service station in the science and technology exhibition area, which can consult information and carry out financial services such as recharging, transfers, loans, etc., and charging all kinds of mobile phones and technology products is also a basic service item.

However, Linto's main purpose here was not to recharge, he used his account to log in to Google Maps, and then turned the tiled map into a three-dimensional format, and the search location was fixed in the southwest of Xianghua Town.

"That place is underground, how can Google find it?" Figley asked, standing aside and clasping his hands.

"How do you know if you don't try? Since there is such a large space underground, it is unlikely that there will be other large buildings on the ground, and it may be around the town. ”

In Linto's vague impression, the stone slab was facing the staircase and was facing up, and thanks to his own small mood at the time, he saw that there were indeed not many people walking on the staircase.

Maybe the black smile used in his ** dose was very small, and he woke up once in the middle of it because of a slight shaking. He had entered the staircase himself, he thought, but it seemed to be in the wrong direction.

What's going on with this sense of disobedience? Is there more than one entrance? Somewhere in Linto's brain began to ache when he thought about it.

Could it be ......

The first time I woke up in that place that looked like a detention room, didn't I find that the stone door behind me could be opened? At that time, I was still looking for a switch, and if it was the kind of person who pushed and pulled it and then turned it off automatically, it would make sense.

Lintor searched further up, only to feel pinprick-like stinging pain coming at him again and again, almost on the verge of giving up.

"It's five minutes, do you have eyebrows?" No matter how well he portrayed the scene, Figley only had a nonchalant expression.

Lintor slowly closed his eyes and took his fingers off the touchscreen.

A pair of warm hands gently hugged him from behind, and a surprised Linto turned around.

It's Lin Yin.

Really, Lintor didn't feel her approaching at all, and this seemingly warm gesture startled him.

"You, what's wrong?"

She let go of her hands so Linto could turn around. Because of the height difference, Lin Yin almost squatted down.

"No, I just want to hug you."

"Aren't I fine now? I haven't seen you for a few hours, right? Linto held up his hand in front of her.

Lin Yin couldn't cry or laugh, she said: "I don't know why, I feel like I feel a little close to you." ”

"It's definitely a delusion." He didn't know why, but he ignored that someone was real.

"Okay, don't sensationalize." Figley walked over to them, "You'd better figure out how to explain it to your dad,"

"What do you say? Daddy knows I'm missing? Lintor's eyes widened.

"Yes, he is suspected of being involved in the murder and is under investigation."

"Then why didn't you say it earlier?" When he heard this, he hurried out the door.

"Done." Figley turned to him and said, "You left when you first disappeared, and now it's time to come back." ”

"So you still think I'm brainwashed?"

"Lintor, ignore him, I'll show you something." Lin Yin walked out of the science and technology exhibition area with him, and the fresh air came to his nose.

She held Linto's hand tightly and walked on the sun-sparkled bend, and the students came out of the building in groups, all talking and laughing.

Lin Yin combed her hair into the shape of a doughnut and stuck it on the back of her head, because it was not allowed to leave it in the laboratory, and if she removed the white coat, she would be no different from the classmates around her.

Some familiar classmates will say "Hello senior sister" when they meet her, and she will stop and respond one by one, it can be seen that the classmates respect her very much, and everyone lives very well on campus. If someone asks him if he would like to be admitted to this university in the future, the answer is mostly yes, and Linto likes the learning atmosphere here, and of course the teaching environment.

Lin Yin will take him to the maintenance room next to the biological research room of the laboratory building, where the analysis and storage of data and information and the commissioning and employment of scientific and technological products are mainly carried out.

Before coming here, Linto had a hunch that the equipment he wanted had been successfully developed. Isn't it possible to see the souls floating around you at any time?

Lin Yin named the product they developed as a bio-based heat source fluoroscopy, which is actually a pair of goggles that can be worn on the head.

He couldn't wait to put it on, and it was indeed as she said he could see a white light, which was in the center of the body, and the more it looked blue towards the surface of the body. Everything around is still the same color, but the color is brighter, which is affected by the brightness of the ambient light. It's not just the camera that's working, because the dazzlingly white ceiling lights don't show the image.

It was a truly amazing feeling, and he found that his hands were a different orange-red color than usual, which illustrated his indescribable excitement at this time.

"I don't understand, what the hell is the principle of this?" Lintor couldn't help but ask.

"In fact, the principle is very simple, it first follows the special phenomenon of human self-luminescence."

"Self-luminous?"

"Uh-huh," Lin Yin explained, "Actually, there are many creatures in nature that can emit light. In addition to the well-known fireflies, there are also earthworms, shrimp, sand silkworms, and even certain seaweeds that can glow coldly. In particular, all kinds of bacteria, fungi, crustaceans, molluscs, fish, insects and some plants are emitting some light information to the outside world all the time; This kind of light is produced due to various chemical reactions in life activities, and it has nothing to do with body temperature, so it is called 'cold light'. ”

"Oh? Can people too? ”

Lin Yin nodded and continued, "Yes, the human body can also emit this kind of light. As early as 1911, a British doctor named Walder Keelner, when he used double cyan dye to paint the glass screen, he first found that there was a halo around the periphery of the human body, about 15 mm wide, and the color was magnificent, flickering and flickering, which was amazing. ”

"All human life activities emit a faint and different, invisible ultraviolet light. This ultraviolet light, called mitotic rays, promotes mitosis in cells. Blood is a strong source of this radiation, and the intensity of radiation varies with physiological conditions, such as disease. Scientists call it the 'glow of life'. ”

"If you've studied physics, you should know that light is particle-based. The basic unit of light is the photon, and the intensity of the light is directly proportional to the number of photons. The number of photons emitted by the human body and most light-emitting organisms is very small, so it is difficult to detect this luminescence with the naked eye alone. ”

"Dad seems to have said that."

"Different parts of the human body, different ages of people, different health conditions of people, and even with the change of people's emotions, the strength and color of the glow emitted by the human body are also different. Not only can it judge a person's health status but it can also be used to diagnose diseases. Therefore, the glow of the human body is actually a window to peek and diagnose physical and mental health. ”

That's why being different from the light she emits? In any case, the glow of the human body is a symbolic representation of the person, an information tool used to examine one's own state.
