Traveling through time with a house, I teach people all over the country how to farm

Then Zheng Sisi cleared her throat and began to explain to everyone the most amazing circular food chain.

She said with a serious expression: "In this vast world, there is an amazing food chain. And standing at the top of this food chain is us humans. We eat grains, and we also consume various animals and plants as sources of nutrition. These foods will produce a series of chemical changes after passing through the human digestive system." Having said that, Zheng Sisi paused for a moment to give everyone time to think and understand.

Then, she continued, “These digested products do not disappear. Some of them become nutrients for our bodies, supporting our growth, development, and daily activities. However, the other part will be excreted through excretion and re-enter the cycle of nature.”

Zheng Sisi emphasized: "This is the wonderful thing about nature. Every organism plays an important role in this chain. The food we eat not only affects our own health, but is also closely related to the entire ecosystem.

That is to say, the food we eat turns into excrement, the excrement turns into nutrients, the nutrients grow plants, and the plants turn into food for humans.”

Zhong Ruiyu screamed: "I will only eat meat and no vegetables from now on."

Zheng Sisi smiled evilly: "Animals also grow up by eating food, it's just an extra process."

Zhong Ruiyu was a fool. He stood there blankly. He was questioning his life. He couldn't accept the fact that he grew up indirectly eating human excrement.

The third prince narrowed his beautiful dark eyes. He grasped a few words he had never heard of, "digestive system, chemical reaction," and chewed them slowly. He wondered where Zheng Sisi learned this. Was it also taught by her master? Where did her master learn this?

You will never find the answer.

Zheng Sisi looked at Zhong Ruiyu's silly look and wondered if she had gone too far. She was a little worried that he would not come back, so she comforted him kindly.

"Don't worry, nature is amazing. The fertilizer disappears on its own after being taken over by nature. The vegetables we eat are also exposed to wind and rain, and have been washed, so they are very clean."

Zhong Ruiyu asked weakly: "Really?"

Zheng Sisi: "Why would I lie to you? Everyone eats like this!"

Zhong Ruiyu then slowly accepted it: "I will ask the cook to wash the vegetables a few more times when I get home."

Zheng Sisi held her forehead with her hand and didn't want to pay any attention to this idiot.

I stopped chatting with him and looked at the sun. Without a watch, I had no idea what time it was.

He said to the servants and guards who were working, "It's time to finish your work. Go back and wash up and eat."

It seems that the circular food chain just now scared Zhong Ruiyu alone.

The sun is still quite strong at noon in February. I have been doing skin care for a few days, but I am getting tanned again and becoming a dark girl. I feel like crying.

Zheng Sisi said to the maid, "Rosewood, go back and remind Qiuxiang to make some bamboo hats or veils. The sun is too hot."

Rose: "Okay, girl!"

She and Lily practice martial arts, and sometimes when they go on missions, their appearance isn't very important.

A large group of people finished work and went to the front yard in a mighty procession.

Zheng Sisi returned to her yard. Xia He and Qiu Xiang smelled the scent on them and ran to the small kitchen to boil water without saying anything.

Zheng Sisi looked so innocent, she raised her sleeve and smelled it, it was indeed a bit embarrassing!

I have to have dinner with my grandmother later, and I don't want to make her feel choked.

Zheng Sisi asked Dongzhi and the two flowers to go back and clean up and take a shower, she could handle it here by herself.

A few of them knew the girl's rules, so they went back to their room to wait for hot water.
