I fought back after reselling my engagement

On that day, the second prince stayed at Baixian Manor and was accompanied by Su Jingzhai. They first visited the farm in Baixian Manor and ate a farm meal. There were sweet potatoes, corn, and cotton here. Today was the cotton harvest, and there were many quilts, winter clothes, and cotton cloth. Some of them were sent to the palace, and some of them were obtained by Su Jingzhai.

Because Baixianzhuang grows sweet potatoes, people in many surrounding villages have planted sweet potatoes and corn this year. Cotton seeds are limited, so cotton will only be promoted next year.

Sweet potatoes can also be harvested if planted in June, which is why there is a bumper harvest of sweet potatoes this year.

Corn seeds were originally the most abundant, and every village planted corn. They were made into corn and sweet potato porridge together with sweet potatoes, which was very effective in resisting hunger.

The former paper mill and printing workshop were rebuilt into a wheel workshop, which was divided into a carpentry workshop and an iron workshop.

Su Zhen took out the design drawings of the bicycle, and then the design drawings of the rickshaw and the unicycle. Finally, he discussed with the craftsmen how to improve the carriage, mainly focusing on producing elastic wheels and increasing shock resistance.

With his guidance, the woodworking workshop was divided into bicycle group, rickshaw group, unicycle group and horse-drawn carriage group. Sometimes they made their own cars, and sometimes they discussed improvements together. Everyone moved into the car-making workshop and their treatment was improved.

Each group has its own ironwork master who can discuss with the carpenter master.

A month later, the imperial court sent a batch of materials, including unknown animal skins, famous colored stones, and some black iron stones.

Su Zhen went to the loom group earlier and took two sewing machine design drawings. It was impossible to succeed in one go. She was just playing a guiding role. Some unreasonable details needed to be improved by the master chef.

To build the Yueyang Weaving Factory, Su Zhen paid one million taels of silver out of his own pocket. As he had no money on hand, he took out his earlier glass and coral jewelry and sent them to auction houses in Jiangnan and Beijing. After a month, he earned 2.63 million taels of silver. With the money, he first allocated 30,000 taels to the sewing machine group and then 60,000 taels to the car workshop. Each group received 15,000 taels of silver.

Su Zhen learned carpentry from a carpenter and iron smelting from a blacksmith. Every night he took out the book "Dongyuan Continent Weaponry" to study. He picked out some monster skins, bones and stones from the materials sent by the court and collected them. Those colorful stones are one of the raw materials for refining magical tools and spiritual tools, and can also be called "ores". The green ones are wood-attributed ore, a kind of refining material with wood spiritual power. When refining the magic weapon of a cultivator with wood spiritual roots, this thing is most indispensable.

Wind is a mutated spiritual root of the dual spiritual roots of fire and wood. Both fire crystals and wood crystals are of great use to her.

Su Zhen studied "The Art of Weapons" at night and spent the day in the iron workshop learning ironmaking techniques. She used the cultivators' weapon-making techniques to forge iron and smelt iron. The black iron delivered to her was only a dozen pounds, which she stored in her space for future use.

The master from the sewing machine group came over to customize several special shapes of ironware, drew the blueprints, and marked the dimensions. Su Zhen and the master from the iron workshop repeatedly refined them and finally met the other party's requirements.

After the first sewing machine was built, it was a bit heavy. You sat on it and stepped on it to make it turn. After a creaking sound, it sewed a belt. However, because it had to be pulled manually, the stitches were not uniform.

Su Zhen proposed the theory of adding cloth to determine uniformity.

She only made suggestions and they were responsible for perfecting the thinking.

This winter, Su Zhen did not get time to retreat. He was busy during the day and had more opportunities to practice in space at night. As a result, his spiritual cultivation did not improve, but his martial arts cultivation became more solid, and he was promoted to a sixth-rank great swordsman.

From September to December, Su Zhen's woodworking skills improved, and even her blacksmithing and iron-smelting skills were not inferior to those of a senior iron-smelter. She could make hatchets, kitchen knives, hoes, wheels, and iron accessories for sewing machines.

Based on modern iron smelting techniques, she created pig iron technology by making coil steel, wrought iron and pig iron. The term "steel made by tempering a hundred times" came from this. With the efforts of her and the iron workshop, they forged the first sword made of tempered steel, which was indestructible and named "Zixiao Sword". After its completion, Chunfeng presented the sword to the emperor.

Bicycles, wheelbarrows for transporting food, and rickshaws for carrying passengers in Yueyang city, three types of vehicles came into being. Even many small families gave up raising horse-drawn carriages, as the cost was too high. Raising horses required a driver. Now that they had rickshaws, they could save on horses and just use rickshaws directly.

The Grand Commander bought five rickshaws at once. Each rickshaw only cost five taels of silver, which was both convenient and affordable.

Although the quality of the rickshaws produced by Baixianzhuang is guaranteed, they were soon imitated after they appeared on the streets of Yueyang City. Not only rickshaws, but also bicycles loved by young people were imitated.

On the sixth day of the twelfth lunar month, the second prince returned from Jiangnan. When he saw the various strange cars in Yueyang City, a smile flashed across his lips. It turned out that he was able to achieve results without taking her with him.

The second prince stayed in Yueyang Prefecture for three days and took away a batch of cars and sewing machines. Yunyifang has purchased six sewing machines. The sewing speed is nine times faster than before. The stitches of the sewn clothes are even and the speed is fast.

Through observation, Su Zhen discovered that with each successful improvement of a generation of looms, the first loom possessed special spiritual power. In the water-powered weaving workshop on the Baixianzhuang River, there were the first loom of the first generation, the first loom of the second generation, and the first loom of the third generation. Later, as the technology of the third generation matured, the first and second generations were eliminated and replaced by the third generation looms.

She put the first loom of the third generation into the space, and the first sewing machine of the third generation into the space, as if she was used to some kind of collection.

After the study in the space was tidied up, it almost became her storage room.

Su Zhen took low-level monster skins from the workshop's warehouse, and used refining techniques to boil them into glue. After several attempts, she finally succeeded and injected air into the rubber wheel. She made a simple air gun based on a modern bicycle air gun and filled it with air. She changed the bicycle wheel from a mixture of wood and iron to a rubber wheel. When riding, the vibration was almost non-existent.

She taught the iron workshop masters how to process monster skins, and then successfully made elastic animal rubber wheels from monster skins, cattle, sheep and goatskins. When used on the carriage, it was more balanced and the vibration was halved.

After Su Zhen refined the animal hide rubber wheel, the craftsmen had become accustomed to her refining the wheels, which gave her great convenience. She began to try to refine storage bags, storage rings, and storage bracelets. She actually wanted to restore the function of the Phoenix Ring. If she guessed correctly, when the country was founded, Emperor Gaozu invited the so-called Mohist giant, who was most likely an instrument cultivator and refiner of low rank. But why would he refine a mermaid golden bead on the Phoenix Ring? According to her guess, it was most likely because he could not open the mermaid golden bead, and could only use it as a small storage cabinet at most. For a cultivator, this golden bead with only a small space seemed very useless.

Strictly following the instructions in the storage bag, the first one failed, the second one failed...
