In recent years, serious land pollution problems have occurred frequently, among which heavy metal pollution in farmland is particularly serious.

Excessive heavy metals may cause plant physiological dysfunction, but even if they exceed food hygiene standards, they will not affect the growth and yield of crops.

As the main producing area of ​​heavy metals, these heavy metal pollutants cannot be degraded by microorganisms and enter the human body through the food chain, posing great potential hazards.

This is also the reason why Xu Qingzhi found that not only was the spiritual energy in this world thin, but even many foods were inedible after she came back from the world of cultivating immortals. In the world of cultivating immortals, everything she breathed in the wind and drank in the dew was full of spiritual energy, but when she came back, she felt that some foods tasted like chewing wax.

Moreover, she lived in the countryside and had seen a lot of things.

Most people have a good conscience and eat what they grow themselves, and sell out what they have. But some people make their own food and sell it out, and they don’t even dare to eat it themselves.

The raw materials for making sauerkraut are collected from the fields, wrapped in salt without washing, and then stepped on in black boots while smoking.

Xu Qingzhi saw it once, and from then on he never ate sauerkraut bought outside, and his family never bought sauerkraut outside either.

Meicheng people have a taste for sauerkraut and prefer another way of cooking. The leafy vegetables are boiled in boiling water and then soaked in a basin for a while. The green leaves turn brown. The vegetables cooked in this way are stir-fried with meat and served with chili peppers. They have a dry vegetable aroma, which is better suited to the taste of Meicheng people than sauerkraut.

There are also people selling bacon, which has been gnawed by rats several times and has been torn into pieces. They use knives to cut off the bad meat and sell it outside.

If you buy imported food outside, you'd better pretend to be blind and deaf. Otherwise, if you knew what the front of this thing looks like, you probably wouldn't be able to eat it at all.

Not to mention the common people who rely on the rice harvest all year round. They have no choice but to plant the land contaminated by heavy metals. In the past, the rules set by the top leaders in this regard were loose, and there were many loopholes in the implementation. In previous years, only the moisture content of rice was checked.

The rice needs to be dry before it can be harvested, so everyone has to dry it before sending it to sell.

But there are ways to deal with this. Second-hand rice dealers will mix the very dried rice with the semi-dried rice, or the fuller rice with the empty-husk rice collected from other households.

That big pinhole-like thing can be inserted into a bag of rice to extract a portion of the rice, and no major problems can be found during the inspection.

If the higher-ups don’t accept it, we’ll send it to the Xiaomi factory.

The Xiaomi factory offers a lower price and sells the inspected rice.

This year they actually started testing for heavy metals, it seems that they are taking this issue seriously.

When Xu Qingzhi thought about the rice that might flow into the market, he felt his heart swell up and was distracted for a moment, and his hand was pricked by a chestnut ball.

The pain in her fingers brought her back to reality. - She was busy until the evening, when Wang Yanmei called to call for dinner, and that was when she finished peeling chestnut balls for the day.

Grandpa saw people and asked, "Zijun, is the school closed for the Mid-Autumn Festival?"

"Grandpa, Dad." Xu Zijun called out to them and nodded, "Yes, the school is closed for three days."

Xu Qingzhi walked in last. As soon as she came in, she heard someone calling her, "Sister."

It's only been a month and she can hardly recognize her brother.

A seventeen-year-old boy changes so fast. The acne on his face has completely disappeared with the care of the spiritual vegetables.

A weirdo looking like a dog.

"Grown taller?" she asked.

Xu Zijun scratched his head and said, "I don't know either. I don't know how much."

Xu Fuqiang stood over and compared them. "Zijun has really grown taller. Last semester, she was only one thumb taller than me, but now she seems to be twice as tall."

"You've grown taller and thinner." Grandpa walked over and pinched Xu Zijun's arm. "Look at how skinny you are. Eat more."

Xu Zijun nodded, "Okay."

Xu Fuqiang went to fetch some medicinal wine and asked a few people who were working to drink it.

Xu Zijun is still the same as when he was a child. Whenever there are elders or outsiders at home, he hides behind Xu Qingzhi like a follower.

Xu Qingzhi went to get some water to drink, and he went too.

He turned the cup around in his hand and whispered, "Sister, I just ate the mooncakes at home. They are delicious. Can I bring some back to my classmates when I go back to school the day after tomorrow?"

"If you want to bring it, just bring it. There are dozens more." Xu Qingzhi said disapprovingly. She drank a sip of water, tilted her head to see her brother's face was inexplicably red, and teased: "Why are you blushing? Do you have a girlfriend? Did you bring her food?"
