Under the combined action of the atmospheric elements and the Yi elements, there is a phenomenon that cannot be clearly explained in the overall evolution of the earth's organisms, that is:

The lower the creature, the higher the degree of evolution.

While humans generally evolved twice and more than 2 thousandths, many invertebrates with simple body structures generally evolved eightfold, and the multifold evolution rate was significantly higher than that of humans. Therefore, after the natural disaster, the Blue Star is several times more dangerous to mankind than before.

While the Blue Star Evolution Organism brings danger to human life, it also brings a chance for survival: organisms that contain trace amounts of harmful radioactive elements, and the content of the elements is not higher than 5 parts per thousand, and can be directly eaten by humans.

The researchers named it: Safe Food.

At present, research has confirmed three points: first, the lower the content of the two types of elements, the more beneficial it is to the human body; Second, the higher the proportion of safe food in the food eaten, the stronger the ability of human beings to resist environmental pollution; The third is the effect of multi-fold evolution of safe food to enhance human resistance, which is significantly better than ordinary safe food.

Since safe food cannot meet the food needs of the people of the whole country, Huaguo classifies edible organisms containing trace amounts or no radioactive elements harmful to the human body, and the content of exterminating elements is between 5 and 15 parts per thousand, as optional foods.

Both safe food and optional food are shown with a green light when tested with a detector. The evolutionary catfish that Xia Qing shot to death, if it was taken to a safe area, could be exchanged for enough rations for her to eat for three months.

Xia Qing, who had eaten enough of the rough compound compressed rations, now only wants to eat meat.

She cleaned up the catfish, chopped it and threw it into the pot, added mountain spring water and boiled it.

Seasoning? Only salt and paprika.

A side dish? No.

No, she has an evolutionary potato seed, six catties.

However, Xia Qing was reluctant to eat it, because it was clearly written in the "Planting Encyclopedia" that this was a safe food with a content of only 2.5 parts per 1,000 harmful elements, and the germination rate was very low, between 30% and 35%.

Of the six catties of potatoes she got, it is unknown how many seedlings she can grow and how many catties of potatoes she can harvest, so she is reluctant to eat them.

Soon, the pan wafted out with an enticing aroma of meat. Xia Qing raised his nose and sniffed it, and determined that the catfish he stewed was more fragrant and less earthy than the stewed fish sold in the canteen in the safety zone.

This catfish, most likely, is safe food.

Although her appetite has doubled after evolution, Xia Qing is still full before she eats even half of this catfish that weighs more than ten catties. Luckily, it's February, so the fish won't spoil at noon until the evening.

In the future, she will have more and more food, and she will have to find a way to arrange the solar panels and refrigerator as soon as possible. But before that, she had to find glass to fill in the windows to fend off the attacks of evolutionary insects or snakes, insects, rats and ants.

Xia Qing put on his big canvas bag and tools, and decided to use the afternoon to inspect the deserted village.

There are three villages in the shape of an inverted zigzag in Lot 3, separated from each other by large tracts of cultivated land. Xia Qing lives in a deserted village near the mountain in the north, with a deserted village in front of the left and a deserted village in front of the right.

The deserted village has been swallowed up by plants, Xia Qing brushed away the wild grass, and Xia Qing saw a lot of human and animal bones that had been gnawed clean.

Xia Qing has seen too many such scenes, and she has long been numb.

After searching the three villages, Xia Qing moved the usable glass home, picked out the suitable tempered laminated glass, wiped it clean, cut it into a suitable size with a glass knife, sealed it with glass glue, and then firmly sealed it with a special sealing strip.

By the tenth year, the building materials produced before the natural disaster had long since passed their shelf life and were no longer usable, and the ones she was using now were brought out of the safe zone.

The natural disaster destroyed the original industrial production system of Bluestar, resulting in many of the materials that could be bought by pressing a mobile phone before the natural disaster became a shortage of goods that could not be found.

These glass glues and sealing strips were obtained by Xia Qing by relying on his identity as the leader of the construction team.

After his father's death, Xia Qing, who was helpless and beautiful, wanted to live comfortably and decently in the safety zone, either with super strength, or with a group of powerful teammates who could deliver his back, or by selling himself for daily life.

Xia Qing didn't have super strength, no one she could fully trust, and she didn't want to sell her body, so she chose to cut off her long hair and smear her face and blend into the construction team.

Earning points is a secondary purpose, and Xia Qing's main purpose is to hide herself, learn construction techniques, and accumulate materials that are not available in the market, so as to prepare for living alone after leaving the safe zone.

Of course, there were also people in the construction team who wanted to fight Xia Qing's idea, but after understanding her strong strength, they all stopped thinking.

After installing the bright glass, Xia Qing breathed a long sigh of relief, and the house was finally solid. Taking advantage of the fact that there was still some time before dark, Xia Qing carried a shovel to the yard next door and dug a pit and buried a large adult, a child and a dog who were covered with wild grass and only white bones.

Both of them and a dog were killed by the evolved plant mistletoe, and judging by their posture, the dog was trying to save its owner until death.

Evolutionary mistletoe seeds can be parasitic not only on tree trunks, but also on animals and humans, and if the host is not aware of it in time and completely remove, it will soon be sucked dry and killed. Xia Qing still remembers that when he first saw the bunches of bright red mistletoe parasitic fruits on the bodies of people killed by mistletoe, he felt that it was the most terrifying scene of natural disasters.

But over the years, the thrills again and again made her completely understand that there is no most terrifying, only more terrifying. Fortunately, humans now have some means of self-protection, as long as they do not venture into uncleared natural areas, they will not be attacked by evolutionary creatures on a large scale.

After burying the family of three, Xia Qing easily cleaned up the wild grass and houses in the yard. This house is under construction, and the two-story main structure of reinforced concrete pouring has just been completed, and it has encountered acid rain and biological evolution, and the secondary structure of the house, doors and windows have not been done. Fortunately, the roof is made of resin tiles, and the homeowner has done his best to protect the house, otherwise the strong acid rain for half a year will be laid, not to mention the concrete, even the steel bars have been poured.

Xia Qing decided to use this place as his warehouse, storing some large but not very important materials, such as farm tools, furniture, wood, building materials, etc.

After cleaning up and turning around, Xia Qing was full of accomplishment, and at the same time, he felt that he should raise an evolutionary animal that could take care of his home as soon as possible.

Both the Advanced Evolution Dog and the Big Goose are fine, preferably the Big Goose because it is vegetarian.

But this is just a thought, it is difficult to find an animal that can be tamed by humans after advanced evolution. Xia Qing didn't think that he had this luck, he could wait for a rabbit to meet one in the territory, and it was most important to plant the land first.
