Lu Xuan's backyard was closed a few months ago. Because Lu Xuan gradually stuffed a lot of messy things in it.

The first thing that caught his eye was a plow. Lu Xuan was born in a rural area and experienced all kinds of manual farming work as a child. Although those things were quickly eliminated on a large scale and the countryside entered a new era of mechanization. But the initial

For several years, that kind of hard work that made life hopeless was still engraved in his soul. Only after experiencing those lives can you understand the true meaning of facing the loess and turning your back to the sky.

The Tang Dynasty in this era still used the long straight shaft plow originated from the Han Dynasty. It would not be until decades later that the Jiangdong plow would gradually appear in the Jiangdong generation, which is what we often call the curved shaft plow.

Naturally, Lu Xuan would not know the design of the Quyuan plow. But he was still able to improve the plows of this era based on his experience in his previous life. In other words, although his official position was not high, compared to his previous life, he was already vastly different.

Don't.

He doesn't need to make it himself. As long as he puts forward an idea and a rough shape, he will naturally be able to motivate enough people to realize these ideas for him. As long as he pays a small amount of money, he can modify his ideas unscrupulously.

, and then let his subordinates experiment over and over again until they find the best choice.

Although the straight-shaft plow can meet basic needs, it is not flexible enough to turn back, and it is too laborious to lift the soil. Most importantly, it requires two oxen to pull in a lifting method. It is a huge waste of human and animal power.

.

After Lu Xuan's transformation, Liping and plow arrows were added. This can adjust the depth of the plowshare (that is, the bottom triangular iron cone), so that the plow can adapt to both deep and shallow plowing. At the same time, the entire upper part of the plow is made of wood.

, the lower half of the plowshare is made of iron. A certain amount of weight is added to the plow wall and the bottom of the plow to move the center of gravity downward and make the entire plow more stable. In this way, the original two oxen lift can now be done by only one oxen.

It has been operated. This is a huge improvement in saving animal power. Even some soft land can be pulled using human power.

After Lu Xuan introduced this improved version of the agricultural plow, without waiting for the prince and Li Mi to ask questions, he directly led them to the next thing. It was a knife, the standard horizontal knife of the Tang Dynasty. The prince took it and simply

I tested it. It was a good steel sword. Although it was not as good as the horizontal sword he gave to Lu Xuan, which was forged from the precious iron from the Western Regions (the prototype of Damascus steel), it was still far beyond the current standard equipment of the Tang Army.

"Sir, do you still know how to forge?"

Lu Xuan did not answer directly, but turned around and pulled open the raincloth on the shelf. Dozens of identical horizontal knives were neatly placed underneath.

In ancient times, it would take several months, or even three to five years, to forge and forge weapons if it was a handed down sword or a famous sword. If it was an ordinary standard weapon, it would be calculated in days. There is a saying that it takes one day to make three weapons.

A good teacher. In other words, an excellent craftsman can only make three ordinary weapons every day.

"I have a skill. If I follow the skill, I can get hundreds or even thousands of these swords every day." After Lu Xuan finished speaking, he walked towards the next target.

It was a shed. As soon as you got closer, you could feel the obvious heat. When you opened the door, you saw that there were a lot of fruits and vegetables growing inside. In the middle of the shed, there was a fire pit. On top of the fire pit, there was a basin of hot water.

, the whole shed was filled with a feeling of dampness and heat.

Lu Xuan didn't know anything about professional greenhouses. This era didn't have modern equipment. He built the most primitive greenhouse heated by a heated kang from the Ming and Qing dynasties. Heating by burning a fire was simple and direct. However, Lu Xuan tried again.

Add water on top to allow the heat to continuously evaporate and increase the humidity inside the greenhouse. This will create a more suitable environment for vegetable growth.

Note that modern greenhouses are all light-transmissive, and the living environment of vegetables is no different from that in normal seasons. Therefore, the vegetables produced are also in perfect shape. But in ancient times, it was not possible to be so perfect, and we could only settle for the second best.

.And Lu Xuan designed the top of the shed to be open. Every day at noon, it is opened for a period of time to add some sunlight, so that vegetables can grow healthier.

Li Mi and the prince felt that they were numb. Everything in the Lu County Lieutenant's house was either worth a thousand pieces of gold, a blessing to the people, or both. But when these things were gathered in the same place

, when in the hands of the same person, apart from numbness, they can only feel a slight fear. No one can understand so many things at the same time that should not exist.

Of course, if Lu Xuan knew what they were thinking, he would sneer at it. In fact, many things have been figured out by some highly intelligent people in the longer past. It is just limited to politics, economy, productivity, and even culture.

Influence. Those things cannot be spread, and in the end they can only be preserved in some rare documents like secret techniques.

There is always a saying in ancient times that the swords passed down from ancient times are sharper and stronger. According to modern theory, this is impossible. Because technology should continue to advance. The later ones are always better than the previous ones. But

In the feudal dynasty, this was a fact. After the Tang Dynasty, the Central Plains began to use a large amount of coal to make iron and steel. Because the temperature of coal could not reach the level of charcoal, and there were impurities such as sulfur in it, the quality of the steel declined.

.This is how the previous statement came about.

It wasn't until the Ming Dynasty, with the emergence of the steel-frying method, that China's forging technology returned to its peak again. Then it all disappeared in the Qing Dynasty...

There was a long silence in the backyard. Li Mi, the prince, and Lu Xuan all fell into a state of silence. After a long time, Li Mi finally spoke.

"Mr.'s talent can be said to be the bridge between seas and golden beams. I hope that Mr. Li will come out of the mountain to assist the prince and bring prosperity together." After Li Mi finished speaking, he bent down heavily. Most of them would not straighten up if Lu Xuan did not agree.

mean.

Hearing Li Bi's words, Li Heng also came to his senses. Now he doesn't dare to regard Lu Xuan as a small county captain. He is obviously a great talent, the kind who is worthy of a big responsibility. Just for this small

There are so many "novel things" in the yard, and I don't know how many more novel things there are in this man's mind.

"Please help me, sir." Li Heng also bowed, which can be said to be a great gift for his status.

Lu Xuan watched the two people salute quietly, and then said.
