The night is very quiet.

Under the dim kerosene lamp, Liu Yu and the old man hid in Liu Yu's bedroom, and Ding Erfat's mother had a surprised look on her face since she had eaten.

She didn't know why the two of them were mysteriously hiding in the room, but after thinking about it, she felt that she shouldn't disturb the two of them.

Maybe they're working on something secret.

Because Ding Erfat's mother is not stupid, since Liu Yu and the old man came to her house, the village has indeed undergone earth-shaking changes, so she feels that as long as those two people want to study, she must give them relaxed conditions.

After a while, the second fat mother returned to her room to rest, while Liu Yu and the old man sat on the edge of the bed at this time.

Liu Yu showed an excited look on his face, and said to the old man, "Take out all your treasures, let me see how many of them are in our organization, how can I say that I am also a member of the organization now, you should let me know." ”

After Liu Yu finished speaking, his face showed a happier look, but the old man smiled and said to him at this time.

"Don't worry, right away."

Then he turned around and began to fumble through the bag he had just brought over.

After a while, the old man threw a black flashlight on the bed, which looked no different from the usual, but actually had an old appearance.

Liu Yu couldn't help pursing his lips, and at this time he said teasingly to the old man, "Aren't you fooling me?" You're definitely not from our organization, maybe you bought it from those stalls in the city, right? Hurry up and show your sincerity, let me take a good look at other good things? ”

After finishing speaking, Liu Yu stretched his neck and glanced at the old man's big black pocket, but the old man tied the bag tightly in an instant.

He pouted at this Liu Yu and said, "Liu Yu, if you don't let you watch it, you should keep some curiosity first, because some things are not seen now, I will choose a certain time for you to watch, but don't worry, I won't hide anything from you." ”

When Liu Yu heard the old man say this, he could only pout.

There was no way, he could only endure that curiosity, and at this time he sat next to him, the old man smiled, took out the flashlight just now, and said to Liu Yu.

"Liu Yu, it's a pity that you are so smart, you don't know anything about the goods, do you see if this is a flashlight?"

Then he gently pressed the button, and suddenly the flashlight emitted a dazzling red light, which lit up the whole room in an instant.

Liu Yu couldn't help but have an extremely surprised look in his eyes at this time, and he asked the old man.

"Aren't you fooling me? It's just a flashlight that glows red. ”

Liu Yu said disdainfully to the old man at this time, but the old man patted him on the shoulder and said to Liu Yu, "If you look at what is on the wall, you will know the magic of this flashlight." ”

Hearing him say this, Liu Yu hurriedly turned his head at this time, and his eyes widened in surprise for a moment.

At this time, he suddenly made an astonishing discovery, and his heart also jumped with joy.

Because there are some spots like little stars on the walls.

Those spots were actually moving, but the speed was really very slow, Liu Yu turned his head at this time with a surprised look, and wanted to ask the old man a question.

But the old man smiled, pointed to the wall and said to him, "Go up and have a look, you will know when you see it." ”

Liu Yu directly threw off his shoes and jumped on the bed, stretched out his head to look, and was surprised for a moment, because the wall was actually full of insects, and those dots were actually insects, and they could still move.

Turning his head, he saw that there were no insects in the room, except for the entire wall.

In other words, the light actually trapped the insects on the wall, and now the red light moved to the other side, and the star-like spots actually moved towards the red light.

Liu Yu felt surprised for a moment, and he couldn't help but smile happily.

"It turns out that this flashlight has such a wonderful effect and can attract these insects."

But after thinking about it, he still doesn't think that this flashlight can be of any great use, this can catch mosquitoes, Liu Yu smiled bitterly.

However, the old man twisted the tip of the flashlight again at this time, and gradually a circle of light appeared, and in an instant, all those insects fell on the bed and the ground, and it was like a piece of rain.

The whole situation was very fast, and even Liu Yu didn't expect it.

Then the old man twisted the flashlight again, and the red circle turned red again, and then he turned off the flashlight, and then said to Liu Yu with a smug look, "Did you see it clearly just now?" ”

Of course, Liu Yu saw it clearly, not only did he see it clearly, but he also saw it with wide eyes, but now countless questions surfaced in his heart.

He first searched the ground carefully, picked up the corpses of those insects, and the insects actually died without any wounds, and then he was amazed, and turned his head to the old man and said.

"This flashlight is actually a big killer, isn't it? It's amazing to be able to get rid of these insects.

As long as you turn it slightly, the aperture can kill these insects, which is too good. ”

Liu Yu said with an extremely surprised look on his face, but the old man smiled and said to Liu Yu, "Brother Liu Yu, you are a little narrow-minded. ”

Then he slapped the flashlight with his hand, and then said to Liu Yu, "Not only insects, but anything with living organisms can directly lose its subjectivity, and then be attracted by this red light, and then I will expand and shrink the aperture like this, and it will die without leaving any traces in the process." ”

Saying that, the old man picked up the flashlight in a mocking manner, and pointed the unturned flashlight at Liu Yu, and suddenly Liu Yu couldn't help pouting and said to the old man.

"I believe it, I believe it."

Looking at Liu Yu's sincere appearance, the old man showed a satisfied smile on the corner of his mouth at this moment, and then he threw the flashlight between the mattresses and said to Liu Yu, "Then you know that I'm not fooling you, right, look at the next one?" ”

Liu Yu smiled, and at this moment, he had a strong interest in the old man's big black cloth bag, and he couldn't put it down and played with the flashlight.

At this time, he finally believed that 100% of these things that the old man took were very precious black technology.
