Zhang Xiaoxia was busy making lunch, Fang Jing was busy lighting the fire, and she didn't pay attention to the little train in the open space.

"Wow, is this what my brother did? What is this? Fang Yuan ran directly to the little train, looked here, touched there, and didn't know what the thing in front of him was.

"I think this is what Brother Jing did, I said that Brother Jing has been mysterious these days, it turns out that he created this thing? But I don't know what this thing is? Qingque approached and looked around the little train, muttering in her heart, she couldn't see what this little train was used for.

"What Brother Jing does must be a good thing, Brother Qingque, don't touch it." Lizhi stood on the side and watched, her eyes full of curiosity, but she was a little worried about whether the blue finch would be damaged.

"Let's go home for dinner first, and ask my cousin what this thing is." The leader of the junior college shouted to everyone, there are still classes in the afternoon, and you can't afford to miss the time.

"Oh, oh, oh, go home for dinner, go home for dinner." Fang Yuan's curiosity was shouted by Da Chu to go home for dinner, and his heart was even happier to eat, eating the most, which was also what Fang Jing had told Fang Yuan before.

Qingque was curious, staring at the little train, he didn't have much interest in going to school, and besides, when he was in Chang'an City, he had already learned, and the basic teachings in the family school were some Mongolian learning, so he naturally didn't care much.

"Brother Qingque, it's time to eat, don't look at it anymore." Lizhi took the other two sisters and shouted at Qingque, Lizhi was just curious about the little train, and she didn't have too many ideas, and eating was the biggest for her.

The four brothers and sisters of Lizhi only had breakfast at the row house, and they usually ate at Fang Jing's house, and a few of the entourages who stayed behind couldn't make delicious meals, and after eating once or twice, they cheekily ran to Fang Jing's house to start eating, Fang Jing didn't say anything, and Chen Erlin and his wife didn't say anything, these little babies are the sons and daughters of today's saints, but they don't dare to say anything, of course, Zhang Xiaoxia is even more distressed about a few little babies, and she changes her way to make something delicious.

Qingque turned back step by step, looking at the little train on the field, she had always been curious about what this thing Fang Jing had created, and she had all kinds of ideas in her heart, guessing the role of the little train, but she couldn't think of a reason.

Zhang Xiaoxia was cooking, Fang Jing had been burning the fire in front of the earthen stove, and when the little babies came home from school, they didn't notice until Fang Yuan came over and held Fang Jing's hand, only to find that the little babies had come home from school and were ready to eat lunch.

"Brother, we saw something in the open space of our house just now, was that made by my brother? What are you doing? Fang Yuan held Fang Jing's hand and asked with a shake.

"Well, this is a thing that my brother has worked so hard to create, but when you come back from school in the afternoon, I'll tell you that you'll have lunch in a while, aren't you hungry?" Fang Jing raised her eyes and looked at her little girl, followed by a large group of little babies, fortunately, this stove room is a bit big, if it was the small stove room before, it would not be able to fit so many people.

"Why are you all here in this stove? Let's all go out, it's going to be dinner in a while, don't you see your aunt stir-frying? They all went to the hall and waited. Fang Jing blasted away the little babies in the stove room, there are more than a dozen little babies here, if you say a word, I say a word, no one can stand so many little baby questions.

Fang Jing didn't want to tell them at noon what this little train was for, let alone turn it on, Fang Jing just thought about waiting for the little babies to go to school for a while, and then actually operate it herself, to see where there was a problem, and if there was a problem, it would be good to have time to repair it.

"The dishes are coming, smoked bamboo shoots and bacon, fragrant dried pork slices, potato pork ribs, stir-fried wild vegetables, fried poached eggs, egg drop soup, how about it? How is my aunt's cooking? Fang Jing brought a plate of dishes to the table and introduced it to the little babies.

"Brother Jing, my aunt's cooking is the best." Lizhi opened a pair of big eyes, staring at the dishes on the large plate on the square table, but her mouth kept swallowing saliva.

"Brother Jing's cooking is delicious, and my aunt's cooking is delicious." Li Mengjiang, as the royal county lord, has always been a fine food and jade, but once he arrived in Fangjia Village, after eating a few meals at Fang Jing's house, he no longer wanted to be in Chang'an, let alone his father and mother, as long as he arrived after school, he would be the first to run to Lizhi's side, waiting to go to Fang Jing's house for dinner together.

"It's still Meng Jiang's sweet mouth, not like Lizhi, with my aunt, I have long forgotten my brother Jing outside the clouds." Fang Jing took the dishes and chopsticks and gave each baby a good meal.

"Brother Jing's cooking is also the best." Li Zhen hurriedly explained to Fang Jing.

"Okay, let's eat, after eating, go back to the back room to take a nap, there is still class to go in the afternoon." Zhang Xiaoxia shouted to a large group of little babies, in this house, Fang Jing felt that Zhang Xiaoxia was becoming more and more like a family.

Fang Jing's potatoes are still the small potatoes left over from last year, of course, the big ones are basically used as seeds, ready to be planted in a few days, and the small ones can basically only be eaten as vegetables, which makes this potato ribs today.

At present, the yield of potatoes is not high, nor is it low, the yield per mu is about 11,200 catties, there is no good enough good seeds, it is impossible to grow potatoes with a yield of three or four thousand catties per mu, which has to be cultivated from generation to generation, this is what Fang Jing needs to do slowly, not to mention that good varieties are rare.

Let's just say that the crops such as corn and peppers that Fang Jing planted last year, compared to Fang Jing's previous life, the yield could not even reach one-third, let alone a few thousand catties, Fang Jing just wanted to breed seeds once a year, choose large ones with full grains as seeds, once a year, and after a few years, they could always improve some.

"Brother Jing, this potato ribs taste so delicious, and this smoked bamboo shoot bacon, which tastes better than fried bacon with bamboo shoots." Lizhi sandwiched the vegetables and sent them to his mouth, this potato was the first time for their little babies to eat it, unlike the little babies of Fang Jing's family, every winter, they were basically roasted and eaten in a charcoal fire.

"It's delicious, you can eat more." Zhang Xiaoxia will sometimes help the two younger girls pick up vegetables, of course, Fang Jing will not pick up vegetables for anyone, including Fang Yuan, who is so adult, and she has to come by herself to eat and pick up vegetables.

Fang Jing took the food and sent it to his mouth, his ears couldn't hear, he couldn't hear, as long as it was time to eat, Fang Jing basically didn't want to speak, as long as he opened his mouth, he would inevitably be questioned by this group of little girls, it was better to eat honestly, but he didn't want this group of little girls to croak around him like hundreds or thousands of ducklings.

After the meal, Zhang Xiaoxia was cleaning up the dishes and chopsticks, and the little babies went back to the back room for a lunch break, and Lizhi naturally followed, but they would not go back to the townhouse where they lived, but only Qingque was sitting on a chair, drinking a bowl of water, thinking about something.

"Qingque, you can also go back to the house and take a nap." Fang Jing opened his mouth and said to Qingque.

"Brother Jing, I'm not going, I want to ask Brother Jing, what is that thing outside? Brother Jing, tell me about it. Qingque tilted his head and looked at Fang Jing with an expectant look on his face.

"Okay, you come with me, I'll show you my great invention, let you see the little train I built, what is the power of knowledge." Fang Jing had a thick face, and directly regarded the steam train in his previous life as his own invention, and this skin was thicker than the city walls of Chang'an.

Fang Jing returned to the stove room, picked up a clay pot, got some charcoal that burned red, and walked towards the small train, after entering the small train, Fang Jing held the clay pot in one hand, opened an inverted alloy door with the other, and stuffed the hole with bamboo sandwich charcoal, after stuffing all the charcoal, closed the door, closed the inverted button, put the clay pot back to the stove room, turned back, and waited for the boiler of the small train to boil.

"Brother Jing, what the hell is this? What are you doing with the wooden sticks on the floor? Qingque has been watching Fang Jing's operation, and still hasn't figured out the situation.

"Qingque, this is called a small train, and you will be able to see why it is called a small train in a while." Fang Jing didn't tell Qingque directly, she kept paying attention to a thermometer tube inside and outside the boiler.

The hardwood laying track, around the entire open space, to say the least there are thirty or forty meters, this is Fang Jing took a long time to make, this laying is simple, each section of the wooden track has a groove, as long as it is aligned, knock it hard, you can dock it completely, plus the weight of the small train is less than a hundred kilograms, and it can't crush the hardwood track, which includes the weight of the two carriages held behind.

At the junction between the carriage and the front of the carriage, Fang Jing still uses hardwood, concave and convex inlays, and a stick is inserted in the middle, which can be rotated completely, and the experimental small train does not need to be perfect.

As the water in the boiler boiled, the temperature continued to rise, and the steam began to fill the entire gas chamber, as long as Fang Jing pulled down the handle of the door valve at this time, the small train could naturally move forward, but Fang Jing was checking whether there was any gas and water leakage at each interface, and he was not in a hurry.

Chen Erlin and his wife finished their work at home, and they also came over, looking at the small train on the ground, weird, this is the only thought in the hearts of the two of them, at most, it can only be like some wooden hand-carved products at home, not much idea.

After Fang Jing finished the inspection, no serious loopholes were found, there were still some small problems, air leakage is the biggest problem with this small train, it is estimated that the seal is not in place, and it can only wait for the experiment to be completed, and then seal it again after disassembly.

Fang Jing stretched out his hand and pulled the door valve of the air chamber, the '......' steam was directed to the air chamber, and only a small part of the steam was discharged out of the car with the guide pipe, making this sound, making Chen Erlin and his wife, and Qingque hurriedly go back, and they were really shocked that this little train could make this kind of sound and spray.

"Jing Wazi, be careful." Chen Erlin and his wife shouted loudly at Fang Jing.

"It's okay, little uncle and aunt don't have to worry." Fang Jing turned around and said, and continued to pull down the door valve.

Although Qingque was taken aback, it was only startled, but at this time, it approached Fang Jing to see how Fang Jing did it just now.

"Nourish...... Click...... Woo...... The sound of "clang......" began to come out continuously, and the little train began to crawl slowly along the hardwood track, Fang Jing stared at the little train that could finally move, thinking in his heart, this hand-built miniature version of the little train was a complete success.

Qingque was taken aback again, this thing in front of him could actually move, and seeing that Fang Jing's hand had left this thing, could this thing move on its own, in addition to curiosity, it was surprise.

"Brother Jing, this ......" Qingque watched the small train in front of him begin to speed up, and began to move at a walking speed along the hardwood track, and felt very strange in his heart.

"Jing Wazi, this ......" Chen Erlin and his wife were even more stunned by the little train in front of them, and they didn't know how to describe it, could this be the monster that Fang Jing had created over time?
