Now the situation is a bit tense, and on January 5, the rebels began to seize power throughout the country, and the People's Liberation Army intervened in the local revolution according to the decision of the central government, carrying out "three branches and two armies". By May, the revolution had spread to Hong Kong. The leftist trade unions took advantage of the Xinpogang factory incident to launch a riot, and martial law was imposed in the East Kowloon area. Hong Kong is full of real and fake grenades, and the people are panicking.

Liu Yimiao felt the tension of the form, but did not stagnate, because she knew that the domestic form did not stop moving forward despite the grimness. On June 14, China tested its first hydrogen bomb; On September 29, China's first-generation self-developed shore-to-ship missile was successfully ignited for the first time, followed by the second and third twin salvos. On October 5, China's first transistor large-scale digital computer 109C was successfully developed; On November 29, China's largest radio telescope was successfully installed and modulated...... and a series of remarkable achievements

Kelp farming in coastal cities is also very successful, and Liu Yimiao arranged his family to develop an engine. The dragon and phoenix fetuses can already walk and call people, Liu Yimiao cried a lot when he left, but the triplets were sensible and said that they would be obedient at home.

An engine is a machine that converts other forms of energy into mechanical energy. The engine has gone through three stages of development: steam engine, external combustion engine and internal combustion engine. Watt's improved steam engine is a typical external combustion engine, when a large amount of coal combustion produces heat energy to heat water into a large amount of water vapor, high pressure is generated, and then high pressure pushes machinery to do work, completing the conversion of heat energy to kinetic energy. And Liu Yimiao is now going to make an internal combustion engine engine, and the engine is the core part of the engine. The main component of the engine is the cylinder.

One of the fatal drawbacks of the steam engine of the external combustion engine is the stiffness of the turbocharger, which will cause the turbocharger to explode, causing many injuries or deaths, so it is extremely unsafe. Therefore, Liu Yimiao's internal combustion engine will also reduce engine explosion accidents.

After Liu Yimiao researched the new engine, he reported it to the above. The new engine was found to be suitable for use in aviation and road vehicles, and the benefits of safety, low fuel consumption, speed and efficiency were all characteristics of the new engine.

The state immediately granted Liu Yimiao's file as a top-secret archive, and also called many experts to continue research. With new ideas and samples, we quickly perfected other aspects of the new engine, which greatly improved China's military and people's lives, and did not rely on the monopoly of other countries on the engine.

Liu Yimiao went home after successfully developing the engine.

"Xiao Miao has good news for you, kelp in the nearby sea entangled an enemy submarine, and our troops quickly surrounded it and captured it. This method of growing kelp is very good," Lei Dajun sighed.

"It's okay if it works, Dajun, my mother is going back, and now I won't go to the hospital, just take them at home" Liu Yimiao saw that her mother always came to take care of her, and she didn't want to go, and the children in her hometown didn't take them, and the children missed their grandmothers after a long time.

"It's not easy for my mother to buy something delicious to take back, but Xiao Miao, you will have to work hard at home in the future" Lei Dajun is also very busy, and he usually does all the heavy work as soon as he gets home, chopping wood and washing clothes at home.

"It would be nice if you spoil Miao Miao a little less, that tin frog is useless, she wants you to buy it," Liu Yimiao said angrily.

"My daughter doesn't hurt herself, who hurts, it's not very expensive, just buy it" Lei Dajun said that his daughter should be pampered, and she won't take it away to the stinky boy in the future, it seems that it is not easy to be his son-in-law.

"The cabbage and radish in the field can be harvested, you can harvest it at home every day, help me make kimchi and hot and sour radish together" There are no greenhouse vegetables now, and the radishes and cabbage that are eaten in winter are radishes and cabbage.

"Okay, I'll help you get it at home every day, go to bed early," Lei Dajun said and put his hand into Liu Yimiao's clothes......

"Mom, it's going to be the New Year, you can go after the New Year" Liu Yimiao was reluctant to let Mrs. Liu go

"Hey, who made me more powerful, what kind of New Year's goods can those fools at home get without me, don't drip your cat pee, I'm leaving, come to Miao Miao, say goodbye to grandma"

"Grandma, goodbye" Liu Yimiao took Ming Ming with one hand and Miao Miao with the other hand and sent Mrs. Liu away

"Mom, today Liu Tiantian wants to kiss Miao Miao and was interrupted by me," Yuan Yuan complained to Liu Yimiao

"What, that stinky boy, the kid owes me a debt, next time let Liu Platoon run ten laps, Yuanyuan did the right thing, it is worthy of praise" Liu Yimiao hasn't said anything yet, Lei Dajun has already shouted, and he usually educates the triplets to pay attention not to let the little boy kiss Miao Miao.

"Miao Miao, listen to Dad, don't let the child kiss your face" Lei Dajun said that men and women should not kiss indiscriminately, and educate Miao Miao to remember.

"Dad, I know" Miao Miao blinked her eyes and nodded.

"Mom, we're going to first grade next year, and we're going to go a long way," Yuan Yuan protested. The primary school here is in the village, and it takes half an hour for adults to walk, and the triplets who have been there mean that their legs are tired and sore.

"You study hard, skip a grade in the future, and you don't have to go so far to finish elementary school early," Liu Yimiao said flickeringly, in fact, junior high school is farther away from the county......

"Ding, the host has completed the restricted-level task: partially solve the national security problem within one year and achieve effective results, reward: the mobile phone design has been sent to the system backpack, please check"

Liu Yimiao thinks it seems good to have a mobile phone next year......
