Technological Empire of the City

In the laboratory, Zhang Yu and Shi Xi, Xu Bomeixue and three people are processing the outer shell of the love ring. The gems of different prices, shapes and colors have been laser cut into rings of different specifications, made of gems. The ring, because of its small size and fragility, should be covered with a layer of coating.

The coating is a transparent liquid synthesized with composite materials. As long as it is wrapped on the gemstone and the coating hardens, even if it is a shallow layer, the gemstone ring will not break anyhow without affecting the viewing. Unless hit hard with a hammer.

"Okay teacher". After coating the gemstone ring, Shi Xi took the love ring to the test bench and said.

Zhang Yu picked up the ring and observed it carefully, and found that the small circular tray on which the instrument was placed was too small to place a large battery on the top of the ring. After all, there were several new functions added to the ring. All functions must have enough power to run.

Seeing Zhang Yu staring at Ji Mian silently, Shi Xi asked aloud: "Teacher, what's the matter?"

Zhang Yu, who was awakened by the words, replied: "The noodles are too small, the big battery can no longer fit, and the small battery is not enough. I am thinking of using something or substance to replace it."

"---". When Xu Bomeixue and Shi Xi heard the words, they were very troubled and meditated.

The laboratory became silent, and the four of them were analyzing feasible solutions. Zhang Yu recalled all the experiments he had done, and found that there was no technology that could replace batteries, even solar energy, from time to time. In the face of receiving sunlight, this wife reduces the practicability of sentiment.

After all, not everyone can let the love ring receive the sunlight from time to time. If it is night or cloudy, doesn't the love ring become an ornament? This kind of unreasonable love ring is not what Zhang Yu wants. Personality determines that Zhang Yu will either not do it or do his best.

"Go back and rest first, and think of a solution tomorrow." After thinking for a long time, and seeing that it was late, Zhang Yu said to the three students.

"Okay, goodbye teacher." Xu Bo, Shixi, Meixue waved their hands and said to Zhang Yu.

"see you tomorrow". Zhang Yu nodded in response.

After packing up his personal belongings, Zhang Yu left the laboratory. Outside the headquarters, in the night, the cloudy wind blew his face, making people involuntarily shrink their heads. In the cold winter of the Star and Moon Country, the night came earlier, only six o'clock. It was dark, and Zhang Yu, who was walking in the cold light, speeded up the pace of going home.

"I am back". Opening the door, Zhang Yu shouted.

Nanny Agnes ran over to help Zhang Yu take off his coat and put it away and said: "The food is ready, by the way, Tang Yan is also here, waiting for you in the hall."

"I know". Zhang Yu nodded in response.

When he came to the hall, Zhang Yu saw Tang Yanzheng talking and laughing with his parents, he immediately walked up to him curiously and asked, "What are you talking about? I heard you all laughing outside."

On the sofa, Tang Yan heard Zhang Yu's voice behind him, turned around, jumped directly into Zhang Yu's arms, hugged Zhang Yu and shouted, "You come back and pull."

"Papa". At the moment when Zhang Yu and Tang Yan were in contact, an electric current was generated on the two of them. A tingling sensation made Zhang Yu's spirit flash. The static electricity of the human body is also an energy source. Why can't you invent one by yourself? , A device that converts static electricity into electricity.

"Damn". Tang Yan exclaimed after being stung.

The shout interrupted Zhang Yu's follow-up thinking, and asked caringly: "What's wrong?"

"Static hurts me." Tang Yan frowned and replied.

"It's okay, I'll rub it for you." After speaking, Zhang Yu stretched out his hand to Tang Yan.

Tang Yan, who thought that there were still people in the room, suddenly blushed and pushed away Zhang Yu's hand, and whispered: "No need, parents are still there."

On the sofa by the side, Zhao Yan said with a smile on her face: "Go ahead and leave us alone."

Zhang Qiang also said: "Yes, it's fine when we don't exist".

"---". Zhang Yu was speechless, you all said that, if Tang Yan really didn't consider you to exist, that would be a strange thing.

Sure enough, Tang Yan hurriedly pushed Zhang Yu away, and stood aside with embarrassed expression on his face. The whole face turned red, and he rolled his eyes to Zhang Yu, which made Zhang Yu very helpless and thought it was not me. He had to change the subject and said: "I'm hungry, let's eat".

At the dinner table, five people were talking warmly. Little Diao Beibei sat on Tang Yan’s lap, raised her head, and kept licking her lips while watching Tang Yanlai. The cute expression made Tang Yan want to rub Beibei in. In his arms, he immediately clamped a chicken leg to Beibei. The bright eyes of Beibei bit the chicken leg and ran away.

"Eh, too ungrateful, right". Seeing Beibei's departure, Tang Yan said depressedly.

Upon seeing this, Zhang Yu persuaded: "Don't worry about that foodie, I'll be back soon."

Since being taken away from Ningxi Village by Zhang Yu, Xiao Mink has been living with humans. After the evolution of evolutionary medicines, it can understand most of human expressions and voices. It also knows that food is not a good word, so it puts it down. After the chicken legs, he stood up and shouted at Zhang Yu with an angry face.

"Squeaky".

Upon seeing this, Zhang Yu scared and said: "If you call again, you will eat mink meat."

"Squeaky". Little Diao Beibei was so scared that he hid in Zhao Yan's arms, and screamed tremblingly, as if he was making a small report.

Zhao Yan quickly stroked Xiao Diao Beibei's back and calmly said: "It's okay, I won't let him eat you."

Little Diao Beibei fawned and rubbed Zhao Yan's hand with her head. She was very proud that she had a backing. She stood up and pointed at Zhang Yu arrogantly, yelling, "Zhang Yu."

"Ok". Zhang Yu passed away with a serious face, and Xiao Diao Beibei was completely persuaded.

"Hahahaha". Everyone laughed when they saw the appearance of Diao Beibei.

In Villa No. 3, Song Bao’s family was also having dinner, but there was one more person on the table, that is, Sun Na, who was sitting next to Song Bao, desperately holding the material to him, there was no meat at all, this way. The suffering caused Song Bao's face to be tangled, and he looked at his parents bitterly.

"Parents, I want to eat meat."

Upon hearing this, Song Wei said bluntly: "If you want to eat it, just clip it, and ask me what I am doing, do you still want your dad to help you clip it".

"---". There was a smile on Zhao Yan's face, and she remained silent.

"I have lost a lot of pounds, I want to eat meat." Song Bao saw that his parents didn't help him, so he pleaded with Sun Na on the side.

Sun Na swallowed the food in her mouth and said to Song Bao: "No, a balanced diet is good for your health. You just eat more meat. Now eat more vegetarian dishes to adjust."

"what". Song Bao opened his mouth wide in disbelief, pondering when he would run away from home again.

The next day, the sun rose more slowly than before. On the streets, the crowd of Xingyue Kingdom began to slowly increase. The crowd repeated their previous behaviors. There were only a few people who went to work, went to school, and took exercise. On the bed, there was Zhang Yu. The warm bed quilt made Zhang Yu very tangled.

"Ah so painful." Zhang Yu said with emotion.

Under the quilt, Tang Yan stretched out his hands and hugged Zhang Yu persuaded, "I want to sleep again."

"No, I just vent it, you can go to sleep, I'm going to do research." Zhang Yu lifted the quilt, and the cold air immediately refreshed Zhang Yu, and his sleepiness completely faded away.

In the underground laboratory of the headquarters, Xu Bo, Shixi, Meixue waited idly for the three of them, waiting for the teacher who likes to sleep in bed when winter comes. This kind of speechless character makes Zhang Yu completely gone in front of the three. Dignity, you must know that those who like to sleep in bed are all children.

"You guys are so early." The alloy door of the laboratory was opened, and Zhang Yu walked in and said with a dry smile.

"Yes, teacher". Shi Ximeixue Xu Bo responded with contempt.

"Then let's start studying." Zhang Yu changed the subject without shame on Lai Bed.

Upon hearing this, Shi Xi asked in surprise: "Teacher, have you thought of a solution?"

Mei Xue asked curiously: "I thought about it for a long time yesterday, but I didn't think of something that could replace the graphene battery. Teacher, what is your method?"

"---". Xu Bo also looked at Zhang Yu curiously, waiting for the follow-up.

"I thought, since the graphene battery is too small and the power is not enough, then we don't want the battery." Zhang Yu explained.

"Oh no, how does the instrument work?" Shi Xi asked without understanding.

"Yes, teacher, you can quickly say, what do you think". Mei Xue asked impatiently.

"teacher". Xu Bo was also anxious.

"Don't worry, listen to me, OK?" Zhang Yu frowned.

"Okay, let's not talk, let's say it, teacher." The three responded.

"First of all, the human body generates a lot of static electricity, which is a kind of energy. If we can convert the static electricity of the human body within the safe range into the electricity required by the sentiment, then what do we need batteries to do, the human body is a continuous supply. The battery is up". Zhang Yu smiled.

"Yes." Shi Xi replied with admiration.

"---". Mei Xue looked at Zhang Yu in admiration.

"But the human body's static electricity is all negatively charged ions. Can it be used normally without positive ions?" Xu Bo asked inexplicably.

Hearing Xu Bo's words, Zhang Yu explained: "So there must be a brand new conversion device that allows negatively charged ions to be used together with positively charged ions. If we understand, let's start the experiment."

"Yes". When the three heard the words, they responded with great interest.

On the test bench, a simulation device began to be assembled. As long as the large simulation device succeeds, it can be scaled down and put into the sentimental circle. With the thoughts of last night, Zhang Yu assembled very quickly. Later, a weird-looking device was born.

"Start it". Zhang Yu ordered.

"Yes". Shi Xi pressed the start button, and the light on the device turned on.

"Whoever puts his hands up to try." Afterwards, Zhang Yu asked the three of them.

"Let me do it". After Xu Bo finished speaking, he directly put his hand on the metal contact plate. He believed that Teacher Zhang Yu would not harm himself, so he was not worried. ,, ..
