Rebirth of the Dead Second Female Lead Becomes the Female Lead Bai Yueguang

"Flashmatic" wireless remote control device, but this device cannot distinguish whether the light beam comes from the remote control, and it must be aligned to control; wireless remote control device uses ultrasound, and each button emits a different frequency, but this device may also be interfered by ordinary ultrasound; infrared remote control uses near-infrared light to transmit remote control commands, with a wavelength of 0.76um~1.5um. Near-infrared is used as the remote control light source because the peak wavelengths of light emission and light reception of infrared emitting devices (infrared light-emitting tubes) and infrared receiving devices (photosensitive diodes, triodes and photocells) are generally 0.8um~0.94um. In the near-infrared light band, the spectra of the two coincide exactly, and can be well matched, so that higher transmission efficiency and higher reliability can be obtained. The most important thing about this technology is the semiconductor device that sends and receives signals. This technology itself was only developed in the 80s in the previous life. As an actuary who only knows the history of scientific research development, Xue Yaya's brain capacity is not large enough to remember all the details. She only vaguely remembers the role of infrared and semiconductors. The person who really perfected it and developed it better than you is Lang Ziyan!

Although it was hard to believe, Xue Yaya had to admit that she was not a genius! If geniuses were also divided into different levels, then she was far from the first echelon! However, a joke about "the fiancé should help his fiancée relieve stress" did not occur to her blood pressure, but only advanced the entire Chinese technology by twenty years! The brief history of technological development, the history of human development, and even the evolution of clothing that she recited in her previous life out of curiosity and boredom were probably just to remind her how amazing her fiancé was!

In the following days, Zhang Zheming stayed at the equipment factory and refused to leave. When someone from the army came to urge him to leave, he just said, "You are just an idiot. If this is revealed, we will be many years ahead of others. Why are you urging us to leave?"

Thinking of the keyword of technological leadership, Chief Engineer Zhang suddenly remembered the enemy spy and said, "Report it quickly! Keep it confidential!"

Wu Youxun and Director Li also became anxious. Zhao Zhigang and Shen Yu looked at each other, one guarding the door while the other went to make a phone call. Soon the troops entered the venue and the people present were quickly isolated for protection. Xue Yaya and others were dumbfounded: "What do you mean? Can't talk to others? What about my grandparents? Will I never see them again?"

As he spoke, his eyes became red, and he looked like he would sit on the ground and cry as soon as they said it! Wu Youxun had a headache: "Don't forget, you are an engaged person, you are an adult!"

This sentence made Zhang Zheming and others curious: "Is this an arranged marriage?"

What era is this? There are still such feudal dregs of thought!

"What kind of marriage is this? It's a marriage between two people who are in love with each other. Alas, it's not! The two families are on good terms and they are both willing!"

Wu Youxun was so angry that he almost fainted. He was afraid that his little apprentice would not play by the rules. He didn't know what was wrong with this child recently. It seemed that she had entered the rebellious period of puberty early. She was extremely tense, but still working hard. He wanted to talk to her, but didn't know where to start!

Adults usually compromise when facing children, especially those who don't know what they will do next. Xue Shanhong, Xiao Meiniang and others who just returned to the village received another invitation from someone special. Lin Fubao's family also has someone. Lin Liyong also works in the auto repair factory. Wang Xiaocai was arranged to work in the textile factory, and the three brothers were arranged to go to school nearby. Xue Qianren's family didn't have anyone, but there was a letter.

The Xue family moved to the city as a group! In this era of famine and poverty, Xue Li Er was assigned to the auto repair shop, Bai Xiuying was assigned to the cafeteria, Xiao Meiniang and Xue Shanhong also went to the cafeteria to serve meals. The three sisters Xue Yunyun were transferred to the high school of the machinery factory. The previous cramming allowed them to pass the high school entrance examination. Xiao Yaya was both happy and a little melancholy: "So our education is too low!"

Xue Qianren felt a little lonely. He wrote a letter home and asked someone to ask Xiaowen privately if he was willing to go to Shanghai to accompany him, but Xiaowen refused. It's not that they don't want to, but they still have three children. The two elders are still alive. Besides, their biological father Xue Libai is there. According to the closeness of their relationship, it won't be their turn! But fortunately, the people below run around for a word from the top. Xue Lisong and Xue Libai were arranged to the slaughterhouse. The condition for Xue Libai to get the job was that his position must be inherited by Xue Qianchi when she came of age. Shi Xiaolan was indignant, but it didn't matter. These two were not her biological sons. She could only look at her son with expectation: "Our Xiaoming will have a great future, right?!"

The drought has not stopped, but the water here is not that dry. The river water level is low, but it is still flowing. Before, Xue Yaya saw her family members looking pale and thin, and privately asked Xiao Meiniang distressedly, "Has the family run out of water? ? Otherwise, with the fish in the small secret realm, they will never starve! Xiao Meiniang smiled slightly: "Then everyone is hungry, can you eat enough?"

Not only can they not eat enough, but they also have to be yellower and thinner than others! As for the fish in the small secret realm, since the drought worsened, Xueli Er and Xueshan Hong went in to check, and the water level inside did not drop at all, so they fished out. The villagers kept catching fish, and everyone's life was not difficult to survive. Compared with the outside world, they were already very satisfied!

It seemed that all the relevant people had been arranged, but Xue Yunyun's smile became more and more dull. Xue Yaya sighed in her heart: She is already a grown-up girl of sixteen or seventeen years old!

It's not that she has no connection with Xiao Hei. Ever since they conspired to cause the landslide, she has become more and more convinced that the fox can definitely cast spells! Under Xue Yaya's coercion and inducement, Xiao Hei had to "give" her a voice transmission talisman. It sounds magical, and it is indeed magical! Whenever Xiao Hei is within 5 kilometers of her, she can feel its presence. It's just that she can sense the other party's presence. If she wants to do something specific, sorry, Xiao Hei is not yet at the level of video calls and cross-race verbal communication. He must see it with his own eyes. Xue Yaya expresses it verbally, and Xiao Hei's body language confirms or denies it.

Xueshanmu was originally somewhat complacent: although his wife was not an educated person like Xiao Meiniang, she was sensible and knew her limits, his two sons were filial, and his daughter-in-law was capable. Even when the drought was spreading, the family did not lack food (in fact, the entire Linjiazhuang production team was not short of food to that extent). But now his troublemaker brother has stopped causing trouble, his two sons have become urban residents, and are eating public food and commercial grain. Looking back at his own family, it seems that they are not as good as the best and have fallen to the bottom.

After much thought, he asked his grandson to write a letter to his cousin, hoping that Xueli Er would also help his two cousins. After all, brothers are the closest to each other when fighting tigers! Xueshan Hong, who received the letter, was in a dilemma. They were now locked up in the machinery factory, so they could only chat with the old employees and had to guard against being tricked by people with ulterior motives. If it weren't for Yaya's insistence, he would have returned home with his wife long ago!

No matter how entangled he was, the first time his cousin spoke, he still shamelessly told Yaya about the letter. Yaya was about to nod, but Xiao Meiniang said, "Are you too bored to have a good life? You asked Yaya to help her cousin find a job? How dare you do that?"

"That doesn't mean that both Lisson and Lieber have jobs--"

"That's what they earned!"
