No matter if you are a human or an immortal, you can still farm for me after traveling through time!

The next night, Li Erlang came to deliver food and asked Ji Qingyue for a list. Ji Qingyue gave Li Erlang the list along with the carrots.

Li Erlang weighed his hands and found a fat white radish in his hand.

This carrot is the most beautiful one specially chosen by Ji Qingyue. After all, this thing represents his face and...

dignity.

"Why did the immortal give me carrots?"

Ji Qingyue put his hands on his hips and said proudly: "I have grown this in the past few days. The others are old. Only the radish looks edible. It is a little thought of mine to give it to you."

Li Erlang couldn't help laughing, but he felt that the tone of Ji Qingyue's words seemed familiar, exactly the same as the tone of praise that Silang would use after completing a task. He was not making fun of Ji Qingyue, he just thought Ji Qingyue was really funny. No matter how hard he tried to hold back his words, he still smiled: "Okay."

"Buy the items at the front of the list if you can afford them. The items at the end of the list are not so necessary. If you don't have enough money, don't buy them."

Li Erlang opened the paper. It was written by Ji Qingyue with charcoal pen. It looked much better than the writing with a brush, but he didn't dare to say it out.

The first ones are all seeds, and several types are specially marked: cotton, potato, corn, sweet potato?

"What are these?" Li Erlang had never heard of any of them.

Ji Qingyue was a little confused. He didn't know whether these things didn't exist in this world or had different names, so he could only describe them one by one.

Finally, Li Erlang reacted to one of them: "Ah, the cotton you mentioned, Immortal, we call it 'Baidiezi'. Brother, I have seen it in the gardens of some adults' houses before. It is a very precious flower. It's not as gorgeous as ordinary flowers, but it's like clean snowballs, so it's called 'Bai Diazi'. But I've never seen or heard of the other things you mentioned."

Ji Qingyue was pleasantly surprised to find one that already met his expectations.

He was overjoyed: "Can I buy the seeds of Bai Diazi?"

Li Erlang was not sure. After all, Baidiezi was an ornamental flower in wealthy people's homes, and he might not be able to buy it, so he did not agree immediately: "I'm not sure, but I heard that it is only found in Tuyuhun and some places west of Shazhou." Bai Diezi, I also heard that Bai Diezi is very fragile, and no matter how carefully you take care of it, it will still fail to harvest for some reason."

Ji Qingyue didn't know how to grow cotton, so he certainly didn't dare to exaggerate blindly. After all, he could only grow the land because of the magical land. So he could only ask around first to see if he could find out how to grow it. "What kind of fragile method?"

"I heard from the caravans going down to the west that Baidiezi is extremely difficult to take care of from seedling emergence to flowering. It is more delicate than wheat and millet. The seeds may die before they are planted in the ground. Now, farmers who grow Baidiezi often have to go to the fields to check for budding seeds. It is difficult to wait until the buds sprout. The buds are very easy to get bugs and blight. Only a few of them bloom successfully in the end. It is a waste of energy and time. It's better to cook corn and wheat. Over time, no one will dare to plant white seeds. Occasionally, if someone does, it's just for rich people to watch."

Ji Qingyue probably knew that this cotton might be really difficult to grow, but compared with its effects, he would have to overcome no matter how big the difficulty was.

He continued to request: "I don't need anything else, I just want Bai Diazi's seed, even just one."

"Okay, if it's not in the store, I'll send someone to look for it."

No matter how embarrassed Ji Qingyue felt, he still wanted Li Erlang to get the cotton seeds. Cotton is really important to people in cold places.

In addition to seeds, Ji Qingyue also wanted fish fry. It would be such a waste not to use such a long stream to raise fish. It would be as uncomfortable as seeing an empty space unused for growing vegetables.

"If the immortal wants to eat fish, I will go to the river to catch them when the weather gets warm."

The more Ji Qing thought about it, he still had no explanation. Forget it, he had to eat in the end anyway.

Finally he asked for some tools.

"Hoe, axe, knife, sickle, plane, chisel?"

Ji Qingyue thought that with these tools, he could slowly specialize in carpentry and make tables, chairs, benches and beds.

In fact, he also wanted an iron pot, but he was not sure whether iron was a controlled metal, how widely it was circulated among the people, and whether it was expensive. After some consideration, he decided to put the iron pot back. Now he can also cook in clay pots. He also thought about raising poultry such as chickens and ducks, but he thought that now he had to rely on Li Erlang for food. If the poultry followed him, he might have to eat one meal and starve for three times. This would put more pressure on Li Erlang, so he didn't have the ability to do so. It’s better to put off raising poultry until you can fill your stomach.

If he wanted to raise chickens and ducks in the future, cages and fences would also have to be put on the agenda. The more Ji Qing thought about it, he felt that he would be very busy in the future.

Li Erlang read the first half of the list, and then continued to look at the back. At the back were items that Ji Qing felt were less important: clothes, oil, salt, sauce, vinegar, and flint. On the contrary, these things were easy to buy.

After reading a piece of paper, there were still a few things on it that exceeded his expectations. Baidianzi seeds were more difficult to handle, and there were iron products. In addition to being expensive, you had to wait for a while to get the goods after ordering. He put away the list: "I will buy as much as possible. Have you thought about everything, Immortal?"

Ji Qingyue felt that he should have thought everything through. With the tools, he could make many things without asking Li Erlang to spend a lot of money to buy them, because transporting them in was also a problem.

Now is the off-season, so no one needs to go to bed early and get up early. In the main room, the women in the family are chatting and making clothes. Li Erlang is not in a hurry to go back to sleep, but continues to stay in the study and chat with Ji Qingyue. He I have been interested in Ji Qingyue’s origins for a long time.

When Li Erlang asked, Ji Qingyue was stunned for a moment, not knowing how to answer.

What does it look like in heaven?

When you look down at the earth from the sky, the view is really good.

Ji Qingyue picked up what he could say and gave full play to the art of speaking: "You and I are just different in the place where we live. Everything else is the same. We also need to eat and sleep. We must respect the old and love the young and act bravely. We cannot get something for nothing."

"So, the immortals know when the sun is closer to us?"

Ji Qingyue didn't expect that Li Erlang would turn the topic to academic research. He thought that he had indeed heard what Li Silang said that night. Maybe he would catch Li Silang and ask him about the cause and effect after he went back, but he couldn't figure out this question in the end. He tossed and turned for a long time. Finally came to him for answers.

He felt funny when he thought about that scene: "What do you think?"

When Li Erlang saw that Ji Qingyue threw the question back and did not give him the answer directly, he felt a little frustrated, scratched his cheek and tried to answer: "Then I will tell you what I think. If it's not right, Immortal Don’t laugh at me.”

Ji Qingyue promised: "I will never laugh at you!"

"When I heard this story, I thought it was all right, but after thinking about it for a long time, I felt that none of it was right." Being able to think like this was beyond Ji Qingyue's expectation. Li Erlang continued: "When the weather is fine, early morning is indeed better than noon." It’s cool. It seems that the sun is closer at noon, but the sun at noon also looks smaller than that at dusk in the morning. It also seems that the sun is far away at noon. Since these two answers are contradictory, I will put them aside for now. I have been thinking these days that it snows. It has been cloudy in the past few days, and it has been very cold both in the early morning and at noon. If the sun is close at any time, why can't it dry out the clouds in the sky? It can be seen that we should not use "the one who is near is hot" and "the one who is big". "Heat" is used to demonstrate the distance of the sun, but I really can't figure out how to demonstrate it."

Ji Qing frowned and squinted as he listened. After listening, he felt very relieved. Should he praise him or not...

Although what Li Erlang said is unscientific, he can still refute two points of view based on his own observations, which is indeed worthy of praise.

"After telling Shiro about this article before, I said that I would only tell him the answer when he felt that both points in the article were wrong. I didn't expect to tell you first."

Li Erlang sat on the chair: "Young man, listen to the teachings of the immortal."

Ji Qingyue waved his hand: "Teaching is not considered teaching, it can only be said to be an explanation, because I also learned it from the research results of my predecessors. Before that, I only ask you one thing. Don't say that I am talking nonsense. My country has a position The great comrade said that we seek common ground while reserving differences, and it’s up to you whether you believe it or not.”

"I understand."

"Let me start with a story. Many, many years ago, there was an explorer. He and his other people organized a fleet and followed the compass... er, it was Sinan, from the local coast. Set off and explored westward for more than two years, they actually returned to the place of departure. At this point, the adventure of the explorer and his team proved a controversial point at the time - is the world we live in a circle? ?"

After hearing Ji Qingyue's story, Li Erlang found it incredible but not so shocked. Ji Qingyue's solemn behavior before the story had made him mentally prepared in advance. After hearing the story, he actually found that he could accept it. story!

"Then what……?"

"Then everyone gradually accepted the idea that the earth is round."

Li Erlang didn't quite understand. What does this have to do with the distance of the sun?

"Because our world is round, the sun is also round, and the sun is shining. When our world spins on its own, there is day and night. When our world spins on its own and around the sun, there is spring and summer. Autumn and winter. If you can't imagine it, find two balls and put them out for a spin."

Li Erlang was confused, and he began to regret his persistence in seeking the truth, because sometimes the truth was too obscure, and not knowing it seemed to be only a kind of happiness. "Tai, doesn't the sun move?"

"Theoretically, we can hold off for the time being." Ji Qingyue knew he couldn't go into more details. "Our world is moving in such a complex way. In the early morning and noon, the sun is actually as far away from us. The reason why it is cooler in the early morning than at noon is because there is a sky above us, which not only protects us but also causes the temperature to rise. difference."

Li Erlang shook his head to wake himself up: "Are you immortals protecting us?"

Ji Qingyue's head was full of questions, what should I say?

"No, like you, I am also protected by this sky. Without this sky, the sun would be stronger than in summer, and we would all be scorched to death."

Li Erlang was so frightened that he shouted "God bless you".

After finishing speaking, Ji Qingyue couldn't help but breathed a sigh of relief, "That's it for tonight. It's too cold. I'll go back to warm up by the fire."

Speaking of fire, Ji Qingyue never knew that the light in the painting could shine through, so he never blocked it. When the weather was still hot, the bonfire burned smaller, but not much light came out, but now, a little behind the thatched cottage The light from the bonfire reflected on Li Erlang's face, just like he was sitting far away facing the firelight, and the entire study was enveloped in a warm light.

When Li Erlang mentioned it to him, he still found it unbelievable. Could it be that this dilemma just means that people cannot come and go freely...

Ji Qing was more thoughtful and planned to use the remaining weeds to weave a straw curtain tomorrow. The weeds that were cut last time were still piled there and had long been dried.

Li Erlang just thought he had heard a bizarre story. He went back and lay in bed, still feeling miraculous about the advanced knowledge he had just come into contact with. The more he thought about it, the more impossible it became. When he finally convinced himself not to believe it, the other side was silently talking again. Accept it, constantly choose between belief and disbelief, push and build your own knowledge and concepts again and again, and the most profound feeling in the end is regret.

If Ji Qingyue knew that Li Erlang would be so uncomfortable when he returned, he would only think: Curiosity killed the dog, but that is the fact, he can't make up a fairy tale to excuse it...

Li Erlang had insomnia. He got up and went to the yard to make two snowballs. He squatted on the ground and turned the snowballs while blowing the cold wind. His hands were red from the cold in the middle of the night.

What the immortal said seems to make sense, but it doesn't seem to be the case...

Finally, his eyelids could no longer hold any longer, and Li Erlang went back to his room in a daze. What he was thinking about in his dream was whether he believed Ji Qingyue's words.
