Looking at the handful of "grass" in Ji You's hand, Guan Ning is very doubtful whether it can eat. No wonder she has such doubts now, because the current environment can't be compared with the ancient earth period. Most plants will suffer from strong radiation, which is harmful to the body.

In today's society, there are two kinds of food supplied to residents, one is synthetic food, the other is natural food. Synthetic food refers to several or more kinds of human edible materials. A large part of these materials are taken from those irradiated animals, plants or minerals, which are processed into various foods after continuous filtration and purification to ensure that they are harmless to human body.

Because these synthetic food materials have undergone deep harmless treatment, they all become colorless and tasteless, and their nutritional value has been lost. With these raw materials, food factories will add essential nutrients to the human body, and then make the most widely circulated nutrients on the market. The better the added materials, the more nutrients, and the higher the price of nutrients.

Nutrients are the basic food, which can ensure the minimum food, clothing and nutritional intake of interstellar citizens. Moreover, the processed raw materials can also be processed. According to different processes and categories, they can also produce synthetic fruits, synthetic meat and synthetic drinks

Because the raw materials of synthetic food are not difficult to obtain, the price of synthetic food is generally not high, which can be affordable by most families who are not rich, which also fully ensures the basic right to survival of every family.

But!

Synthetic food also has a very big disadvantage. It is not helpful to the growth of human mental strength.

That's why natural food is so popular.

However, although the fields covered by human beings now involve eight galaxies, natural food is extremely scarce, because cosmic radiation and various harmful substances in the universe cover almost every inch of the land that human beings set foot on. Even every planet on which human beings live must have an artificial protective cover before human beings can move freely on the planet they live, From radiation and other hazards. Only a few planets survived. These lucky planets provide mankind with most of the natural food sources.

Of course, it is not enough to rely solely on several planets to supply natural food to humans in several galaxies. Therefore, countless agronomists and scientific researchers have invented and created various methods to improve cultivation, grow natural food and raise natural animals, but the cost of these technologies is very high, which is also the reason why the price of natural food has been high.

These are omitted.

Guan Ning took the "grass" in Ji You's hand and observed it carefully. He found that it was ordinary grass, nothing special. Guan Ning thought for a moment and said, "Ji pomelo, is this grass really edible? Does it contain radiation?"

Plants containing radiation are harmful not only to the body, but also to the mental power. Guan Ning is very vigilant about this. It is not easy to improve the mental power. Everyone present knows and feels the difficulty of improving the mental power

It was said that Ji pomelo asked everyone to dig grass that might have radiation for everyone to eat. For a time, many people hesitated.

Ji grapefruit said, "do you usually only focus on training? Don't watch popular science such as nature and plants? This is a unique wild onion on your planet, and its radiation content is less than 0.1%." the federal food safety administration stipulates that food with radiation content less than 0.1% can be eaten directly. However, edible plants with radiation content less than 0.01% can be judged as natural food.

Guan Ning: "!"

The head of the next regiment also stared: "is there such a thing?"

Ji grapefruit suddenly grabbed the wild onion and stuffed it into his mouth. He smashed it and chewed it. He ate it twice and said, "this food has pungent taste and warm nature. It also has the effects of sweating, expelling cold and detumescence."

Guan Ning and the head of the 1st Regiment: "!"

At the same time——

The students watching the war outside the screen also stared one by one. There were many action groups among these students. They immediately began to query according to the wild onions in Ji Grapefruit's hand. After this query, they found that it was true!

"My God!"

"I'm ignorant!"

"I've lived in Nami for so long that I didn't know that Nami still has such a magical wild onion?"

"Me too. I didn't know before."

"Cough... Sorry, I don't pass the natural science of Nami star, because I haven't heard of it before."

"I've heard of it, but I only know that this plant grows on a beach in the rear of the First Military Academy of the League! It's said to be wild onion. In fact, its shape is no different from wild grass, so many people can't tell which is wild grass and which is wild onion... This also ensures its survival and reproduction..."

....

Facing the surprised expression of Guan Ning and the head of the 1st regiment, Ji grapefruit said with a smile: "it's no wonder you are ignorant, because all you think about every day is fighting and all kinds of fierce star beasts, and you don't care about this kind of grass that is not dangerous and conspicuous."

After listening, they were a little ashamed.

Guan Ning was very careful. She thought of a question, "since it is a direct edible plant, is it a protective plant? Is it a kind of grass at the bottom of the prison? What if we eat it or collect a lot... What if we violate the union law?"

"Yes, I have a sense of hardship." Ji pomelo praised and explained with a smile: "The radiation content of wild grass is less than 0.1%, but it is not up to the standard of natural food. Extensive use has no gain and auxiliary effect on the mental power of human body. Moreover, it has strong reproductive ability. A large area grows along the beach. In addition, it is also easy to transplant. Agronomists take it to other planets for planting, which is basically easy to survive. One problem with wild onions transplanted to other planets is Its radiation content is higher than that of namicin, basically between 0.5% - 5%, which is still not up to the edible standard. "

"Therefore, it is not in the list of cherished animals and plants." Ji pomelo looked at Guan Ning and others and said with a smile: "rest assured and eat boldly."

Guan Ning and others brightened their eyes. The head of the 1st regiment patted his chest and said loudly, "I'll send someone to dig right away."

After thinking about it, the head of the 1st regiment asked, "how much do you want to dig?"

Ji pomelo pondered and said, "dig up the weight you think is enough for your group to eat."

As soon as he said this, the head of the 1st regiment understood. He immediately said in a loud voice, "I'll send someone now."

Ji grapefruit said: "pay attention to the momentum when digging. It's better to let the opposite side vaguely notice that we're moving."

Eh?

A light suddenly lit up in the eyes of the regiment leader: "what are we going to do?"

Ji pomelo looked at him with a smile and said, "it's common to dig wild vegetables."
