Wenwen gave her fourth brother a thumbs up. She didn't expect that the silly fourth brother was so smart.

Wenwen looked at the net and thought that it could also catch pheasants. That was a good idea.

"Fourth brother, where did you get this net? It's a little small. If you had a bigger one, wouldn't you be able to cast a net to catch fish?" In this era of material scarcity, everyone's mind was filled with how to get food.

"Don't think too much. This small net can't catch any fish." Yu Xunting said.

"Don't even think about the big net. I snatched this small net from my classmate." Of course, I paid for it.

"Let's go down the mountain and go back to stew some chicken." Without thinking too much, Wenwen took the lead and walked in front.

A few people first went to the captain's house to return the hatchet.

Only the village chief, Old Li, was at the Li family. He said, "Return one first. You still have to collect the firewood when you get home, so take that back and use it. Take this one with you when you go up the mountain tomorrow."

"Thank you, village chief. Is the team leader not at home? We would like to ask if we can lend some food to the village." Yu Xunting asked.

"Jianguo went to town early this morning. It's going to snow soon, and they're worried the cowshed won't be able to withstand it, so they need to report it to the commune," the old village chief said with a smile. Yesterday, Jianguo told him the whole story.

"There's definitely no way we can borrow a lot of grain," the old village chief sighed. "Lijiawan has many mountains and little land. Even in a good year, there's barely enough to eat. There won't be much left over."

"Let's borrow some first. Once we have stockpiled all the firewood, we'll go to the town to buy some," said Yu Xunting.

The old village chief shook his head. "We can't buy much food in town either. There are purchase limits now. Food is too scarce."

Several people felt bad after hearing this, and they were also given a purchase limit. They couldn't do without food, as there were so many of them.

"Does the county also have purchase restrictions?" Yu Xunting asked

"That's not very clear, it should be better than the town."

At this time, Wenwen saw a little girl coming out of the house. When she saw that they were strangers, she went back into the house.

Wenwen poured out half of the kiwi fruit from the basket and said, "Village chief, these are the kiwi fruit we picked on the mountain. We're giving them to the children as snacks."

"There are still lantern fruit at this time. I thought the children in the village had picked them all."

Children nowadays don’t have snacks, and these small wild fruits are their favorites.

"Village chief, I want to exchange some potatoes with you. Also, I want to exchange some with anyone who has more pickles." Wenwen asked.

"I can exchange potatoes for about a hundred pounds, but I don't know about pickles. I'll ask you when the time comes." Pickles are the business of the women in the family, and the old wife should know about it.

"Village chief, I'll come back to get the potatoes." Yu Xunting said.

When Wenwen was about to walk out of the yard, she caught a glimpse of several tree roots as thick as sticks placed at the base of the wall.

Wenwen couldn't help but look at it a few more times. The more she looked at it, the more it looked like cassava. But isn't cassava a plant that only grows in the south?

"Village chief, what is that?" Wenwen asked.

Seeing that Wenwen was interested in the tree root knot, the village chief decided to tell these city kids about it as well.

"I don't know what it is. It's dug up from the mountains. You can't eat it, it's poisonous. Several people died from it during the famine that year, and no one dared to dig it up anymore."

Wenwen was delighted when she heard that there was one on the mountain.

She motioned to Yu Xunting to give her the hatchet. She chopped it off with the hatchet, looked at it carefully, and then scraped off the skin to see. Now she could be sure that it was cassava.

"Village chief, you said there are some on the mountain. Are there many?"

"There are so many of them. You can't eat them, but they grow very fast. A whole hill is almost covered with them." The village chief said, "Girl, you can't eat them. They can kill people.

I'm just showing you this, so you can't eat it if you dig it up in the mountains in the future," the village chief said solemnly.

Wenwen smiled and said, "As long as there are more, it's good. Now we don't have to worry about food."

"Village chief, this is called cassava. It is poisonous if eaten directly, and excessive consumption can be fatal, but the toxins in this cassava can be removed," Wenwen explained.

"Village chief, can you give me this cassava?" Wenwen asked.

The village chief quickly waved his hands: "No, I can't give you this poisonous thing. What if something happens?"

"Village chief, I know how to remove the toxins. It'll be fine." Wenwen held up a lump of earth that looked different from the cassava. "Does this wild yam also grow on a hill?"

This is wild yam. When you first cut it, you can smell the scent of yam. The skin is thinner than cassava, and there are no lines in the middle when you cut it. Cassava has a thick skin, and there are lines in the middle when you cut it.

"You recognize this one too? It's not in the same piece. Although it has a different shape, we dare not eat it for fear of something bad happening."

"Not only are the two different in shape, but the leaves they grow are also different. Cassava grows like a sapling, and its leaves open like palms. Wild yam is a climbing plant, with smooth leaves that look like closed palms, and the flowers on the vines look like short beans.

Wenwen talked about the differences between the two plants. Why did she know so clearly? In her previous life, she had visited a farm and knew the difference between cassava and yam, and the difference between yam and wild yam.

In later generations, cassava is a very common food. Many fried potato chips are actually cassava chips, and the pearls in pearl milk tea are also made of cassava flour.

The old village chief was stunned. This girl from the city really knew this tree root knot.

"Yes, that's what he looks like."

"Village chief, I'll take this with me. Tomorrow you take me to the mountain where cassava grows."

"Girl, can this really be eaten?" Isn't it poisonous? Can this poison be removed?

"Village chief, please believe me." Wenwen put the cassava and wild yam in a basket and took it away.

"Little sister, do you really know how to detoxify this?" Wen Xiao pointed at cassava.

“I know!”

"How do you know?"

Wenwen winked at her fourth brother: "You read it in a book. Haven't I been reading a medical book recently?"

Wen Xiao understood immediately. He had forgotten the mystery in his sister's dream. "So, how are your medical books going?"

"Traditional Chinese Medicine is so extensive and profound that it cannot be learned overnight. Besides, Chinese Medicine requires a master to teach it. I am just laying the foundation now, and I will learn it quickly when the time comes."

Yu Xunting looked at the sharp expressions on the brother and sister's faces and pretended not to see them.

They returned to the educated youth site, put down their things and got busy.

Yu Xunting went to the village chief's house to get potatoes. Although they wanted to exchange them, they were short of everything and could only buy them with banknotes.

Wenwen asked her fourth brother to boil water and kill a chicken. She peeled the cassava and soaked it in water. To remove the toxins in the cassava, it had to be soaked for six or seven days and then boiled several times so that the hydrogen cyanide in it would evaporate and the toxins would be gone.

Lanlan wanted to pick up cassava peels to play with, but Wenwen quickly stopped her: "If you get them on yourself, you'll be so itchy that you'll cry."

"Your brother is chopping wood. Can you go and pile the firewood for him? Once you're done, I'll give you a chicken leg." Wenwen coaxed her away, saying that she must not let her see them slaughtering the chicken.

Wenwen saw that Wenxiao had finished boiling the water and said, "Fourth brother, you kill the chicken and I'll cook it."

"Okay, bring a bowl. The chicken blood can't be wasted." Wen Xiao went out with a knife.

Wenwen took the bowl, thought for a while, put a little salt in the bowl, and then added some hot water to let the salt melt.
