From space, the Earth's surface is still covered in snow and ice north of 20 degrees north latitude and south of 20 degrees south latitude. Only the middle equatorial region is exposed to the sea and land. Sea levels drop as ice sheets trap freshwater on land. The Malay Archipelago, which was originally an island, is joined by a single landmass, and Singapore is landlocked. In the South China Sea, only the exit of the Bass Strait in southern Taiwan remains, turning from a marginal sea into a bay.

In the southern part of the South Bay, there is a coastal human city - New Fuzhou City. The city consists of a number of buildings of the same height forming a circle with a radius of 40 kilometers and an average height of 120 meters. The building is closed with fiberglass between the top of the building. Four triangular fiberglass fibers form a pyramid shape that directs radiant rainwater into the building's radiation-proof stormwater pipes. From here, rainwater leads directly to underground waterways and discharges into the sea.

The fiberglass is coated with a coating that filters out harmful wavelength solar radiation, and the glass has a lilac appearance.

The city circle is surrounded by a continuous building that surrounds the entire city, equivalent to the ancient city wall.

Outside the city is a tundra with the occasional few trees. The temperature varies between 0 °C ~ 12 °C, and the temperature in the city is maintained at 25 °C all year round by the adjustment of the city's central air conditioning. The energy of the entire city comes from the combustible ice at the bottom of the South Bay Bay, and platforms in the South China Sea convert the combustible ice into liquid natural gas, which is transported by LNG ships to the port of New Fuzhou.

The energy company in New Fuzhou City turns the natural gas and water vapor into hydrogen, which is delivered to a hydrogen fuel cell power station. Hydrogen fuel cells have a conversion efficiency of 80%, which is more efficient than gas turbine power plants 300 years ago, and the product is only water. Ideal for closed cities, where fuel cell power stations become the only option in a situation where humans fear nuclear energy.

There is a dedicated fuel cell power plant to supply the tram system. Unlike the crossed tracks of 300 years ago, the trams of this era operated completely independently. The circle of tram tracks that stretch outward from the city center is called "ring track", and each track runs independently, completely unmanned and 24 hours a day. In addition to the circumferential orbit, there is also a "radial orbit" that radiates outward from the center. Viewed from above the city, the tram track network resembles a spider's web.

The sliding friction coefficient of the rail and steel wheel is an order of magnitude smaller than that of the rubber tire and the ground. The tram does not jam traffic and can travel at a constant speed. Trams can operate 24 hours a day, while private cars may be idle. As a result, the energy consumption and price of trams are much lower than those of private cars.

Coupled with the fact that the city is closed, parking spaces are not only tight but also extremely expensive. Therefore, from the bottom to the wealthy in New Fuzhou City, they gradually gave up their private cars and used balance cars and trams to travel.

This balance bike is a little different from 300 years ago, with a box between the handles that allows the tablet to be embedded. The balance bike itself is a large mobile battery, and the tablet can be charged wirelessly. Under the pedals, in addition to the two large wheels, there are two auxiliary small wheels that allow braking in an emergency.

In addition to balance bikes, people commonly use AR glasses, where the appearance of AR glasses is no different from ordinary glasses, but the lenses can display additional information that is not available in reality. The AR glasses are extremely lightweight, and the electronic bag is linked by a line, the glasses are equivalent to the display screen, and the electronic bag is equivalent to the main unit. People can access the Internet in real time through AR glasses, and the online ID itself is also a real identity. When the online blacked ID appears in the AR glasses, the glasses will be automatically covered with a black shadow. Online life and real life become one.

In front of the tram stop, Li Xu stepped on a balance bike, carrying a white electronic backpack and wearing white AR glasses. 15-year-old Li Xu is 175 cm tall, with long white hair hanging down to the waist, a small face with goose eggs, curved willow eyebrows, long eyelashes trembling slightly, apricot eyes like a clear spring, pink cherry mouth slightly open, a white fairy skirt outlines a budding figure, and snow-white long legs looming.

All the memories of his previous life were awakened, and Li Xu remembered the oath he made in his previous life, and he would definitely eliminate the pain of a woman's childbirth. So from the age of 5, she took the initiative to learn various courses. She also remembered Yan Maolin, and she didn't know if he had also crossed over and where he was.

Unlike in previous lives, there are no schools and no government in the afterlife. Instead, there are various educational institutions and knowledge-sharing platforms where people sell their knowledge and those who need it can buy courses. There is no government and no taxes. People buy the services of the executive company directly. Administrative companies make profits by providing public services.

It has been said that interest is the best teacher.

As long as people learn voluntarily rather than forced to learn, they can maximize their learning efficiency, which is similar to the best teacher who is interested. This is exactly the educational philosophy of later generations, efficiency first. Those who are willing to learn and want to learn should study hard, and the society provides all resources, and will not restrict the flow of educational resources because of identity. On the contrary, the only way to acquire knowledge is money.

Relying on the consciousness and knowledge accumulation of his previous life, Li Xu relied on his mother's sponsorship to complete the relevant knowledge of biology in his previous life at the age of 15, and obtained biology degree certificates from famous educational institutions such as New South and Changkong.

In this life, she is closer to her dream, not only because she has a first-mover advantage, but also because the current human beings are all women, so she has more resources to invest in the research of artificial uterus and the topic of female reproduction. Li Xu believes that she can realize her dream of removing pain for women.

Today is her 15th birthday, and it is also the day when her mother stopped providing funds as agreed.

Children in later generations are more independent, and they will choose to be independent when they are between 12~18 years old. I live in a rented house and work on my own to support myself. In this way, you can gradually develop your ability to live independently, and you can also avoid the conflict between adolescent rebelliousness and your mother.

In later generations, it was not popular to raise daughters to prevent old age, but to provide for the elderly by themselves. The relationship between mother and daughter is an independent personality, not an accessory or a pet. If you want to have a child, you can give birth, and if you don't want to have a child, you choose not to have a child, it is completely a matter of personal choice. This kind of free choice allows people who are willing to have children and love children to have children at the right time. and not to be forced to give birth to a child when it is not like giving birth, causing a conflict between the mother and the daughter.

Making children independent is the trend of this era, and Li Mu understands this. At that time, she also left her mother at the age of 15 and became independent, and decided to raise a child by herself at the age of 17. But when I really became a mother, I understood my mother's mood back then.

Reluctantly!

Li Su has been very sensible since birth, taking the initiative to take on housework when Li Mu is busy with work, and taking the initiative to take care of Li Mu when she is sick. It can be said that Li Xu is her intimate little padded jacket. If you go out to rent a house to live, will you not be able to eat well? Bad rest? Will you be bullied? Wait a minute.

But this was the agreement between the two at the beginning, and by the age of 15, Li Xu would go out independently, and the mother and daughter would live their own lives. Children are ultimately weaned.

"I'm back!" Li Xu put the balance bike and shouted into the house.

"I'm back!"

Li Mu wore an apron and rushed out with a spoon.

"I'll prepare some sauce for you, it's your mother-in-law's family heirloom. Do you want to learn? ”

"Hmm~ Okay."

"Have you found a house?"

"A shared apartment building near the 15th ring track would be more suitable. Check it out after eating. ”

"When you go, pay attention to the property and don't be deceived." Li Mu patiently advised, "Are the things packed?" Don't leave anything behind. Do you want me to take a look for you? ”

"Got it." Li Xu looked at her nagging mother and said gently.

"Do you want to extend it for another year? Do you have enough savings to get a job? If you don't have enough money, tell me if you can't do it. ”

Li Xu looked at her helpless mother, inexplicably distressed, and hugged her mother with both hands.

"Pay attention to your body, rest when you need to rest, and don't get too tired."

"Do you still want to go......" Li Mu's tears rolled in his eyes.

“…… Well. Li Xu held back tears and nodded.

Li Xu's hand caressed her mother's back.

"Thank you for raising me, thank you."
