Female-to-male: I live on farming

After Qin Ke returned, he placed it in their old house, which happened to be next door, so it was convenient.

But the most important thing right now is to let him take a shower and change clothes, otherwise Qin Ke really can't stand the smell on his body.

It was already June and the weather was getting hotter. Qin Ke gave him a set of old clothes and after thinking for a while, asked Li Nanqiao to take him to the river to take a bath.

"Here, this is Han Qi's indenture contract, please keep it, madam."

Generally, the family’s money and important things like land deeds are kept in the study, and Lu Youqing is usually in charge of their management.

After Han Qi washed and changed into clean clothes, his original face was revealed. He looked handsome, but too thin. When he stood up, he was a head shorter than Li Nanqiao.

"Okay, let's eat first. You haven't eaten well for many days. Be careful not to eat too much, otherwise your appetite will be ruined." Qin Ke sat down first and said to Han Qi who was standing stiffly beside him.

"Oh, just sit down if I tell you to. The boss and my wife are both very good people. You will get to know them slowly in the future." Li Nanqiao slapped him on the shoulder, forced him to sit down, and sat next to him.

He was a little embarrassed when he started eating and only dared to take the dishes in front of him. Later, probably because he was very hungry, he ate faster and faster, and he wanted to bury his head in the bowl.

Lu Youqing's appetite has not been very good since the weather started to get hot. He put down his chopsticks after eating a few bites.

Qin Ke thought about it and realized that in ancient times there were no air conditioners or electric fans. Rich people used ice to get rid of the heat, but ordinary people did not have such conditions.

The ancients would chisel ice and store it during the cold winter months, and then take it out and use it in the summer of the following year. Storing ice was not an easy task, and the storage capacity was limited, which led to the high price of ice in the summer.

He knew how to make ice from saltpeter. Saltpeter was sometimes used as a medicine and was cheap and not difficult to buy.

Qin Ke was inspired. Isn't this another way to make money? He immediately gave Li Nanqiao some money and asked her to buy some saltpeter to try.

Lu Youqing looked at him in confusion. Qin Ke smiled and raised his eyebrows at her, pretending to be mysterious and said, "Give my wife a surprise then."

When Lu Youqing heard this, she knew he was going to do something weird again, so she just let him do it.

Although saltpeter was available for purchase, the output was small. Li Nanqiao drove a donkey cart all over the town before he bought a basket of saltpeter. Qin Ke took a part of it and asked Li Nanqiao to put the rest in the warehouse.

He locked himself in the study and did not let anyone in.

"Madam Lu, what is the boss going to do?" Li Nanqiao was also confused.

Lu Youqing was as calm as ever: "You'll know later."

Qin Ke found two copper basins of different sizes, filled the large copper basin with water, and then placed the smaller copper basin in the large copper basin. Seeing that the water in the large copper basin submerged the small basin, Qin Ke took out saltpeter and poured it into the large basin, shaking it continuously. The saltpeter continuously absorbed the heat of the water in the basin, and slowly, the water in the small copper basin turned into ice.

Seeing that the experiment was successful, Qin Ke pushed the door open with a smile, eager to give Lu Youqing a surprise.

"Madam, come quickly." Qin Ke went straight to Lu Youqing who was sitting under the pavilion, took his wrist and pulled him towards the study.

Lu Youqing reluctantly followed his force and stood up, following him obediently to see what he was doing next. Her expression was full of joy and excitement.

As soon as Lu Youqing entered the study, he felt a cool breeze blowing towards him, which formed a sharp contrast with the hot weather outside.

"Is it ice?" Lu Youqing saw the basin of ice placed in the middle of the study. If he wanted to use ice in summer, he had to store ice in winter. However, their family had no conditions to store ice. Thinking of the saltpeter that Qin Ke had just asked Li Nanqiao to buy, he had a guess in his mind.

"Is it saltpeter?"

"My lady is smart. It is saltpeter," Qin Ke led her to a basin full of ice and explained, "When saltpeter is dissolved in water, it absorbs heat, so the water cools down and turns into ice."

Although Lu Youqing didn't quite understand the chemical principles involved, she smelled a business opportunity. The price of saltpeter was very low, and during the summer vacation, ice became a hot commodity, and the profit could not be underestimated.

Looking at Lu Youqing who was deep in thought, Qin Ke smiled and squeezed her hand: "What are you thinking about, madam?"

Lu Youqing came back to her senses, glared at him, and said, "Selling ice in summer is a feasible business, but this method needs to be kept secret."

"But the production of saltpeter is low. Li Nanqiao said that she has bought back all the saltpeter in the town. If we want to use saltpeter to make ice, then we need a lot of saltpeter."

"Then let's go to Jincheng to buy it. Jincheng is one of the most prosperous places. There must be enough saltpeter there. Let Nan Qiao take Han Qi with him and buy as much as they can." Lu Youqing made a prompt decision and arranged the next things.

Although Li Nanqiao was still confused, she knew what to ask and what not to ask. The next day, she packed her luggage and drove to Jincheng with Han Qi.

The house suddenly became empty. After Qin Ke had dinner in the evening, he took Lu Youqing for a walk in the village to help digest the food. The villagers of Qinghe Village could often see the two of them walking hand in hand in the village.

After realizing his feelings, Qin Ke began to look for various opportunities to get close to her, whether it was taking a walk or sticking to her to teach him how to write. As long as he had free time, he would want to stick to her.

And since the last incident of dysmenorrhea, Qin Ke clearly found that Lu Youqing no longer resisted his approach and some intimate actions, and sometimes she would even take the initiative to get close to him.

Walking has almost become their regular activity now. The atmosphere in the countryside is quiet and peaceful. Qin Ke likes this kind of life very much. Occasionally, when they are walking, they will stop by the fields to inspect the fields. Watching the seeds that they have planted with great effort sprout, grow and bear fruit gives him an indescribable sense of satisfaction.

"Is it almost ripe?" Lu Youqing squatted down holding her dress and looked at the green watermelon. When Qin Ke described it to her at the beginning, she found it difficult to imagine, but now those descriptions were presented in a concrete way before her.

Qin Ke squatted beside her and tapped the watermelon rind with his fingers, making a crisp sound.

"It's almost ready. It will be ready to eat in about seven days. Put the watermelon in an ice container and it will be cool and refreshing." According to the watermelon planting guide given by the system, it will be mature in about a week.

Qin Ke held Lu Youqing's hand tightly, stood up slowly, and then looked at the vast expanse of green watermelon vine fields in front of them. The breeze blew past, bringing a hint of coolness, and the green leaves on the vines swayed gently with the wind.

This field of watermelon vines is like a green ocean, full of vitality and vigor. As the wind blows, the watermelon vines make a slight rustling sound.

Lu Youqing turned her head to look at Qin Ke, and saw that he was staring at her with gentle and focused eyes. She smiled slightly, and her eyebrows curved.
