Chapter 308 Liu Qi is born
Of course, it is only the year 2050, and the Blue Star's rotation has not stopped yet, so the Blue Star at this time is not in a global frozen state like the Wandering Blue Star.

The surface of Blue Star is still full of lush plants and laughter, and it is even more prosperous than before.

Because as the intensity of sunlight increases and sea levels rise, some plants grow more happily.

But this is just the final prosperity!

So the year 2050 passed. Of course, Liu Xiu's sixth generation, Liu Peiqiang's son Liu Qi, was also born safely in this year.

Naturally, according to the hierarchy, Liu Qize had to call Liu Xiu his grandfather, and Liu Qize was also Liu Xiu's great grandson.

However, the time of happiness is always short-lived. Eight years have gone smoothly. For Liu Xiu, almost sixteen or eight years have passed in his life. But for Liu Peiqiang, these eight years are not only his happiness but also his life. It made him miserable.

Because once you have gained something, you naturally don’t want to lose it again, and it is naturally very painful when you lose it, because his dear wife Han Duoduo eventually got cancer because of her long-term work in space.

Of course, getting cancer from working in space is only one aspect. The other aspect is that the sun is approaching helium flash, so it is naturally becoming more and more unstable.

Solar storms and increased radiation are the real causes of Han Duoduo's cancer. In fact, not only Han Duoduo, but more people who live and work under the surface sun for a long time have a much higher cancer incidence rate than before.

It was during the eight years that the Blue Star's rotation slowly slowed down that more than 90% of the plants on the Blue Star were tortured to death.

In the eyes of many people, as the Blue Star's rotation speed decreases, it may just be longer days or longer nights, and it is not something that cannot be defeated.

Instead, it dropped directly to more than ten degrees below zero, or even dozens of degrees. In addition to the colder and longer nights, what is even worse is the ecological environment. Fortunately for humans, electric heating can be used during the long nights, because with the development of planetary engines, In construction and use, electricity has reached the point where it can be used almost free of charge.

For example, when the originally twelve-hour night becomes twenty-four, or even forty-eight or even longer, the temperature at night will not drop by just a few degrees or more.

A little bit of heat leakage from planetary engines and fusion is enough to drive many generator sets, so energy is not an obstacle to human development.

And not only that, as the planetary engine on the equator continues to exert force, the spin speed of the Blue Star is naturally getting lower and lower.

But in fact this is not the case, because as the days and nights get longer, it naturally brings a series of problems.

Of course, the same is true during the day when the sun is shining on it. On the contrary, long-term sunlight makes trees, flowers, and other plants begin to evaporate a lot of water and wither.

However, humans can use electric heaters to keep warm, but plants cannot. Although many plants have the ability to withstand cold, it is based on the gradual cooling over a long period of time, and the sudden cooling of more than ten or dozens of hours is much greater. Basically all plants cannot adapt.

With the death of a large number of plants, the original oxygen content of Blue Star naturally began to decrease rapidly. After all, although wild animals in the wild also died along with the plants.

But the eight billion Blue Star humans in the world are still living well by relying on unlimited power heating!

As long as a human being is alive and does not enter a special state, such as hibernation, he will consume 0.75 kilograms of oxygen and exhale 0.9 kilograms of carbon dioxide every day. In this way, eight billion people have to absorb 6 billion kilograms of oxygen and exhale 72 kilograms of carbon dioxide every day.

The total mass of the blue star's atmosphere is about one millionth of the total mass of the blue star, which is about 60 billion tons. Calculated based on the atmospheric oxygen content of 21%, it is 1,260 trillion tons. The oxygen seems to be enough for humans to live on Blue Star for a long, long time.

But in reality, this is not how it is calculated. Blue Star humans are very delicate about the oxygen content. When the oxygen content is lower than 19.5%, or higher than 23.5%, it will make people feel uncomfortable. Not adaptable, and a number higher than this will also make people feel uncomfortable. Therefore, the oxygen inhaled in the hospital is not pure oxygen at all, because if pure oxygen is breathed, it will kill someone in six minutes.

However, this is only oxygen. The content of carbon dioxide in the air is about 0.03%, and about 0.04%. If the carbon dioxide in the air reaches 0.04%, dizziness and shortness of breath will occur.

When it reaches 5%, dizziness will occur. Once it reaches 10%, it will kill people. It is precisely because of this that lighting a stove to keep warm in a closed room in winter is naturally an act of seeking death.

Of course, the stove with a chimney is excepted, because the stove with a chimney sends the burned carbon dioxide outside the house, and of course the same is true for the perylene kang.

Of course, the death of plants will naturally mean a large reduction in grain production, but fortunately, Liu Xiu had already established a large number of artificial powder processing plants as early as four years ago, and under the situation of almost unlimited supply of electric energy , which relies on artificial powdering to produce synthetic nutritional pastes that can be supplied in basically unlimited quantities.

But to be honest, the taste of this thing is really not that good. Although it can ensure that people will not starve to death, no matter how it is made, it does not taste as good as food made from natural ingredients.

Fortunately, although people are picky eaters and hate artificial baking powder, pigs and some farmed animals are not so picky about artificial baking powder and other artificial organic substances.

Therefore, after the establishment of the artificial fixing powder factory, the Blue Star humans at this time are much better than the original Blue Star humans.

At least Liu Xiu preserved the survival of all Blue Star humans and prevented Blue Star humans from falling into the tragedy of being directly reduced by half.

"A big watermelon, cut in half with one knife, half for you and half for mom!"

It was Liu Peiqiang who spoke. During his vacation, he took his son and Han Duoduo, who had terminal cancer and had only a few days to live, to play with his son Liu Qi in a park full of snow.

After Liu Peiqiang made his son laugh, he called Liu Qi to his side and took a group photo of the three of them with a camera that could print instant photos.

However, Han Duoduo felt that the photos taken with the camera were not good-looking, so she took them with her mobile phone and then retouched them after taking them.

However, Liu Qi was naturally very curious about photo editing on mobile phones, but while playing around with Han Duoduo, he accidentally knocked off the hat and wig on Han Duoduo's head.

However, eight-year-old Liu Qi immediately started crying when he looked at Han Duoduo's bald head. Seeing this, Han Duoduo immediately comforted Liu Qi.

Although Liu Qi was only eight years old at this time, he already understood the meaning of life and death, so he naturally understood that his mother Han Duoduo would not live long and would leave him, so he naturally cried sadly.

When Liu Peiqiang saw this, he quickly got up and put on Han Duoduo's wig and hat, and then comforted him. Of course, at this time, Liu Peiqiang's heart was moved by Liu Xiu's proposal.
