I traveled through the plane space with the trading system

This time, Meng Kexin asked Meng Fan to drive the helicopter, and it took half a day to return to Glory City.

It was summer when Meng Kexin went out, and it was already autumn when she came back.

It was the harvest season, and this year the Glory Dynasty had a bumper harvest of wheat, rice, soybeans, potatoes, and sweet potatoes thanks to the high-yield grain seeds provided by Meng Kexin.

Meng Kexin looked at the bountiful harvest scene and generously bought a harvester from the mall.

Ye Muyuan looked at the big thing, not knowing what it was, and asked in confusion: "Xin'er, what is this?"

Meng Kexin stroked the harvester, her eyes gleaming with excitement. "This is a harvester. It can harvest crops quickly, much faster than manual labor."

Ye Muyuan opened his mouth in surprise after hearing this, "So powerful?"

Meng Kexin smiled and said, "Of course, with it, we can save a lot of time and manpower. But this machine is from the future, so we have to find a source for it."

Ye Muyuan thought for a moment and said, "It's okay. I'll just say that I had someone assemble it secretly."

Meng Kexin nodded. In the current Glory Dynasty, Ye Muyuan has the final say. If he said so, no one would dare to express a different opinion.

"In that case, let's drive this machine into the fields."

As she spoke, she started the harvester. The machine made a huge roar and began to shuttle through the fields. Wherever it passed, the crops were neatly cut.

Ye Muyuan watched this scene with deep emotion, "Xin'er, you brought not only high-yield seeds, but also these advanced tools. The future of Glory City will surely be even brighter."

Meng Kexin smiled and nodded. She looked forward to seeing Glory City become more and more prosperous with her efforts.

The honored officials and people watched this big guy shuttle through the fields, harvesting all the crops wherever it went.

The most incredible thing is that this machine can actually separate wheat into grains directly, which made people exclaim in admiration and talk about it.

"This machine is so powerful! It doesn't even require people to harvest." An official exclaimed.

The Minister of Revenue was overjoyed. "That's right! With this giant, our Glory Dynasty can reclaim a lot of arable land. Why should we worry about the people having nothing to eat?"

Seeing his daughter driving the harvester, Meng Weiyuan waved at her and said, "Xin'er, come down and let Daddy try."

Meng Kexin jumped down with a smile, and Meng Weiyuan flew up and sat steadily in the driver's seat.

Meng Weiyuan excitedly operated the harvester and galloped across the fields.

Wherever it passed, wheat fell down and the grains poured into the carriage like a golden waterfall.

Everyone was amazed, and Meng Kexin smiled proudly.

However, at this moment, the harvester suddenly stalled.

Meng Weiyuan jumped out of the cab, checked it over and shook his head helplessly.

Meng Kexin stepped forward and comforted him, "Dad, don't worry, I'll see if I can fix it."

She looked at the machine carefully and found that a part was broken.

But in this day and age, finding the right parts is not easy.

Meng Kexin decided to use her knowledge to try to make a substitute.

After several days of hard work, she succeeded.

The harvester roared again, and Meng Weiyuan was so excited that tears filled his eyes.

This time, the father and daughter drove the harvester together, and the joy of the harvest was beyond words.

As the crops were stored in the granary, Meng Kexin began to invent new things.

She thought of modern flour mills. If a flour processing machine could be created in this world, it would save a lot of manpower.

So, she locked herself in the room and started to draw. One day, Ye Muyuan came in and Meng Kexin handed him the drawing she had designed, but Ye Muyuan couldn't understand it.

"Xin'er, what is this?"

Meng Kexin explained, "This is a machine that can process wheat into flour. Here's the blueprint. I'll show it to you once the skilled craftsmen from the Ministry of Industry have built it."

Ye Muyuan's eyes widened in shock. "Xin'er, you're so smart! I almost feel like I'm not worthy of you."

Meng Kexin said proudly, "This is just the beginning. I'm also planning to design an oil press."

"What is an oil press?" Ye Muyuan asked.

Meng Kexin smiled and said… "It's a machine that fries soybeans into vegetable oil. Nowadays, people eat lard, and cooking with this kind of oil is not tasty. In fact, many things can be fried into oil, such as soybeans, rapeseed, corn, peanuts…"

Ye Muyuan took the flour processing blueprint and said happily, "Xin'er, you continue with the design. I'll hand it over to the Ministry of Industry and have them manufacture it according to the blueprint as soon as possible."

Ye Muyuan immediately took the blueprints to the Ministry of Industry and handed them over to the craftsmen. After studying the blueprints, the craftsmen began to manufacture the flour processing machine.

While waiting, Meng Kexin devoted herself to the design of the oil press, constantly revising the sketch and carefully calculating various data.

Soon after, the flour processing machine was finally completed. Ye Muyuan couldn't wait to drag Meng Kexin to watch the trial run. When he saw the white and delicate flour being produced continuously, he was excited.

"Xin'er, we succeeded! We succeeded!"

Meng Kexin was also very excited. She said, "Ayuan, my oil press design is almost finished. Actually, I believe that there are experts among the people. You can also give them rewards to encourage them to invent. With rewards, people will be more motivated. With all kinds of machines invented, the whole country will become more and more prosperous. Don't you agree?"

Ye Muyuan nodded, "Yes, you are right. Maybe in the future we won't need people to fight in wars anymore. Machines may also be able to go to the battlefield."

Meng Kexin thought about the wars in the future, and saw that they were all high-tech!

"Indeed," Meng Kexin agreed. "Future wars will likely rely more on technology and machinery. If we can develop more advanced weapons and tactics, we can reduce casualties."

Ye Muyuan nodded and said thoughtfully, "Not only that, if we can cultivate more scientists and engineers and develop our country's scientific and technological strength, we may be able to create more powerful combat robots in the future."

Meng Kexin's eyes flashed with excitement. "Yes, combat robots! They are free from emotional and physical limitations, can carry out dangerous missions, and protect the lives of soldiers."

The two of them got more and more interested as they talked, as if they had seen what future wars would look like.

Ye Muyuan decided to set up a special scientific research institution in the country to encourage people to actively participate in scientific and technological innovation.

Meng Kexin was lost in thought: "Perhaps their family traveled through time to improve the technological level of this world and allow the Glory Dynasty to complete its entire industrial advancement."
