As the sun gradually set, the lights suddenly turned on as the twilight drums sounded.

....

"Monster!!" Zhang Zhen was so frightened that he sat on the ground, he could guarantee that no one had gone up to light the light just now, why did the light come on? Thinking of some legends of Ma Qiang, Zhang Zhen can already be sure that it is a monster on it.

"I said, old master, look at it, where are there so many monsters..."Although Gan Shi was also dumbfounded, he was still calm, or he was a little ecstatic now.

As far as the eye can see, there are more than a dozen lights in this cafeteria, eight or nine of which are on, and in the distance, scattered lights can be seen.

It's so easy to distinguish, it's so different.

Yan Rou stepped forward to help Zhang Zhen up, pointed to the lamp and said, "Look, is this light similar to lightning?" ”

"Similar... Appearance... Wait, you mean you guys trapped lightning in this thing? ”

Zhang Zhen suddenly felt that he might not have woken up, how could the lightning be trapped.

Gan Shi stood on the stool and wanted to get closer to observe the spells that could trap lightning... This is the Immortal Law!

At this time, a group of people rushed in, led by Yang Chi, who was holding a small notebook, and when he saw Lin Huan, he hurriedly stepped forward and hugged his fists and saluted, "Uncle Lin, are you back?" ”

Lin Huan was still indulging in the shock of the electric light, and when he saw Yang Chi, he hurriedly asked, "You came just in time, I heard that you are studying with Ma Lang now?" Yan Rou said that this thing is called an electric light? Why can I turn on electricity? We didn't see anyone coming, did we? Come and explain it to us."

"Report to Senior Yang, eight of the twelve lights are on, and four are not on." A teenager dressed in Mr. Xuetang's clothes said to Yang Chi.

"Okay, make a note of the location, take it down tomorrow, and you go to the next area to record."

"No!"

After sending the group of people away, Yang Chi sat down and explained to Lin Huan.

"This lamp does use electricity, Mr. built a hydropower station in the valley, the hydropower station can generate electricity, and then connected to here through wires, now there are hundreds of bulbs up and down the Red Star Camp, but the quality of these bulbs is not very good, Senior Brother Yan Fa has been trying to solve this problem with people in the past few days."

？？？

There was a question mark on the head of Lin Huan and the three of them, what was he explaining? We understand every word of this passage, but we don't understand a single sentence when it is connected.

"You talk slowly, first of all, what are you doing with Ma Lang now, and who are those people just now? I know one of them, it seems to be a former outcast, why is he wearing Mr. Academy's clothes? Lin Huan decided to take his time.

"Mr. called us scientific research students, saying that it means science graduate students, for the time being, there are only five people, Qingcheng, Lime, Lu Yun, me and Yan Fa, and then we are now each with five people as assistants, by the way, I heard that Yue Yang seems to have been forced to enter the laboratory by Uncle Yue, I'm afraid he will be the sixth person soon, most of the five people we brought are the original homeless or our teenagers from Dasong Village, Mr. said that it is easy to remember things when he is young.

Now Yan Fa and I are in charge of the research of generators and light bulbs, and Qingcheng and they accompany my husband in the mine to do research on hydraulic hammers and batteries. ”

Yang Chi explained briefly, and then pointed to the bulb and said, "This bulb is glass on the outside, and carbonized bamboo wire on the inside, Mr. said that in fact, the best material is tungsten filament, but we have not been able to make it, this bulb can be lit for more than 20 hours at the longest now, the main problem is the air inside, the night before, because there is no bulb, the filament is exposed, and we have to change the filament after a while, Mr. changed it several times and wanted to sleep, but now it can be lit up for a night, However, there seems to be some problems with the air pump we made, of course, it may also be that there is a problem with our bamboo wire, we found that the degree of carbonization and thickness of the filament will affect the life of this bulb, and Mr. said that the bamboo on an island in the east is the most suitable for making a bulb...."

Speaking of light bulbs, Yang Chi began to gush, Lin Huan had already given up anyway, he was old, and he didn't want to be a scientific research student, if he didn't understand, he couldn't understand it, but Zhang Zhen and Gan Shi were not, the two of them came here for the legendary secret book, what kind of glass, electric light, and what kind of mud are obviously not things in the world, that is, on the secret book... I don't want to pull down a single word.

But I don't understand this, what should I do? The two of them were anxiously scratching their faces and cheeks, eager to split Yang Chi's head, what are they talking about.

Gan Shi felt that he had said that he had said less about watching a day...

In the end, Zhang Zhen and Gan Shi didn't understand why the lightning in the sky could be stored in glass, as for the glass, they had already understood that this thing was burned, but why it could become such a transparent thing, they still didn't quite understand...

The firing utensils they had seen were all pottery, and a few glasses, that is, ancient glass, were not so transparent.

Zhang Zhen and Gan Shi were arranged in a room and lay on the bed, both of them couldn't sleep.

This Red Star Camp seems to be weird and weird everywhere... It doesn't seem like a place in this world that should be.

What is written in the Secret Books?

Sleepless all night, the two used a toothbrush and toothpaste for the first time, they were reluctant to use this thing in Jizhou, and went to the canteen to eat, when eating, they were all dead looking at the light bulb to eat, the diners on the side were not surprised, when the light bulb was just hung up, thousands of people ate with their heads held high, that is called a spectacular.

"May I ask Mr. Jizhou Ziming?" A voice came from behind Zhang Zang, Zhang Zang looked back, I'll go, who is this?

In front of him was a beggar with messy hair, red eyes, and tung oil on his clothes... No, looking at this dress, it looks like a gentleman.

Zhang Zhen and the others already knew how to distinguish the identities of the people in the Red Star Camp through their clothes.

"I'm Zhang Ziming... You are? ”

"Ah, in Xia Anping Yanfa, I have heard Mr. Da's name for a long time, and I learned that Mr. is here, so I came to ask to see him."

"Yan Fa?" Zhang Zhen suddenly remembered, isn't this person one of the five scientific research students that Yang Chi said yesterday!

"Oh? Have you heard of the old man? Zhang Zhen glanced at Gan Shi with slanted eyes, Gan Shi snorted, and continued to drink soy milk with fritters, the food in this canteen tasted really good, and the food was fresh, all of which had not been added outside.

"Of course, sir's name, it's like thunder! I wonder what the gentleman is here for? ”

"I heard in Jizhou that there is a Mr. Ma in Youzhou, who has extraordinary knowledge, so I came to study abroad, by the way, why are you so... What does it look like to be so tired? ”

Zhang Zhen didn't know what to say, if he lived in the afterlife, he would know that there was a word specifically to describe Yan Zhuang's appearance.

Polytechnic male...
