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

Zheng Sisi took action as soon as she said it. She ran to the small kitchen, added water to the pot and started to light the fire.

It just so happens that you will need to soak the seeds in warm water for an hour.

When Dongzhi saw this, he quickly came to take over the task of making fire.

Zheng Sisi ran back to clean the sweet potatoes and potatoes, picking out the ones with holes and damage. As long as they were not rotten, they were all edible.

After counting, he directed three people to carry the sweet potatoes and potatoes to the side room and germinate them in the dark room. When the sun was bright, he took out the winnowing basket to dry the rice and corn.

The water in the kitchen was boiling, and Zheng Sisi ran to the kitchen to get all the water out in basins and buckets. Zheng Sisi herself was impressed, how busy she was!

Seeing that there was a lot of residue in the kitchen after the fire, he shouted to someone to bring in some sweet potatoes.

The three of them moved quickly and brought in eight or nine selected sweet potatoes.

Zheng Sisi looked at them blankly for a while without saying anything. She took the sweet potatoes and dug a hole in the kitchen. Then she put all the sweet potatoes in, arranged them neatly, and covered the sweet potatoes with fire residue, covering them tightly.

Zheng Sisi stood up and said, "It will take a while to bake the sweet potatoes. I have prepared gifts for you. Do you want to go and have a look first?"

Zhong Ruiyu asked: "Is it sent by your master? What gift is there? Is there a mirror?"

Zheng Sisi: "You'll know in a moment."

The three of them went to the reception room, and Zheng Sisi went back to her room to get a gift.

After a while, Zheng Sisi came to the reception room with a small wooden box. After sitting down, she opened the lid and took out three exquisite watches. These were the old quartz watches that her grandfather used to wear.

Each person handed over one, and the three of them received the gifts. They had no idea what they were, so they turned them over and over in their hands, looking at them.

Zheng Zhiyuan had experience and knew that the gift from his cousin must have a purpose, so he asked, "Cousin, what is this gift and what is its purpose?"

As soon as he asked, the other two also looked at Zheng Sisi with a thirst for knowledge.

Zheng Sisi cleared her throat and said mysteriously, "This thing is magical. It's called a watch. It's a magical device that records time."

The three of them looked at Zheng Sisi as if she were a fool.

Zhong Ruiyu said quickly: "Miss Zheng, don't treat us as fools. Time is so illusory! This little thing can record it."

Zheng Sisi was angry: "If you don't believe it, just give it back to me."

The three of them put their hands behind their backs while holding the gifts. How could they take the gifts back after getting them? They just didn't want to listen to her nonsense.

Zheng Sisi: "Really? My master told me that. Now, let me ask you, is a day made up of twelve hours?"

Zhong Ruiyu: "Yeah, but it's not written on this thing!"

Zheng Sisi: "Just listen to me first. This thing is used to record time. I'll tell you how to read it."

The third prince saw that Zheng Sisi was serious, and when he saw her stretch out her hand, he handed the watch to her.

Zheng Sisi took the watch, put it on her wrist, and said, "The watch is worn on the left hand, with the protruding part facing outwards. This protruding mechanism is used to adjust the time, so you don't need to touch it."

Then her slender fingers gently pointed at the constantly rotating pointer inside the dial.

She said softly, "Look, the longest and thinnest hand on this watch is the second hand that records time! Every time it moves one small grid, it means one second has passed. And we have to start counting from the small dot at the top. When the second hand makes a complete rotation around the dial, it means that sixty seconds have passed."

The three of them stared at the moving second hand, and their eyes followed it around.
