Then everyone saw a seed machine. This seed machine was different from the previous one. Although it had a trench opener under it, there were two wheels next to the trench opener. This wheel obviously seemed to have a transmission device. Although there was a funnel on it, it was only put in by manpower. And this kind of trench was very poor in its "automation". Because once the seeds were put in, it had to be sown continuously. Once it stopped, the seeds would continue to fall and waste the seeds.

When human and animal power are tired, the speed will slow down when it is tired, and the seeds continue to fall, which may cause the density of seeds in local areas to increase greatly, which is not good for balanced planting. Therefore, this worm is not suitable for much worse than later seeds. As for this worm, there is no function of covering soil, so the effect is much worse than later leaf seeds. Therefore, Jing Wen invented the worm seeds, which is probably much better than this worm.

"You see, I found that the underside of this spider seeder is very similar to the inside of the trench opener. However, when you see this wheel, when we are moving, this wheel will drive the spring inside and then leak the seeds step by step. We will only leak seeds during the travel process, and once we stop, we will not continue to leak seeds. This seed pipe can be selected in thickness, and can choose seeds of different density. There are also things for covering soil behind, so this one can be used to cover soil. So, as long as we have this thing, sowing is no longer a problem." Jing Wen said.

Suddenly someone asked: "What is this spring made of? What is it made of? This thing seems good. If nothing unexpected happens, I'm afraid it can be used in many places. But what exactly is this made of?"

"Haha, after the spring is pressed down, he will recover himself after it is released. I made this with the steel of the soft sword. This is a good thing, I used it to produce springs. I didn't expect that it could actually produce springs. It is because of this spring that my seeder can achieve it." Jing Wen said.

Just now, when Jing Wen was making a seeder, he suddenly realized an important problem, that is, the problem of springs. In Jing Wen's understanding, there was no spring in ancient times because springs needed spring steel to make. However, when Jing Wen was in a headache, a technician who made swords took the initiative to take out a kind of steel, which made Jing Wen overjoyed. Because this steel is very soft, has strong flexibility and is very elastic. Jing Wen immediately asked what this was, and the technician immediately answered that this was the soft steel used to make soft swords.

When Jing Wen saw the so-called soft sword, he remembered the martial arts TV series in later TV. There were often some swordsmen holding soft swords that were as thin as paper and as flexible as springs. Jing Wen thought it was impossible at first, but later he heard the words of this sword craftsman. This soft sword actually existed as early as the Eastern Jin Dynasty, and a poet specially wrote a poem for the soft sword. Although this soft sword is more inclined to the side, it also exists after all. This is enough to show that mild steel actually existed in ancient times, and this mild steel is actually spring steel, which can be made into springs.

When Jing Wen saw this scene, he immediately used this mild steel to make a spring. Although the spring is relatively rough, it is actually enough to bear the needs of this primitive tool. If the spring problem is solved, the subsequent invention will be very easy. This kind of leaf seeder was actually invented by a Western musician, which has to be said to be a satirical sarcasm. However, since this thing is from a foreign devil, Jing Wen brought it and had no idea to take care of others' scientific innovation.

"Look at it. I can completely reduce the waste of seeds in this way. Usually, one acre of land requires at least two liters of seeds, and using this seed machine, we have completely achieved intensive cultivation. We can save seeds and make a mu of land use at most one liter of multiple seeds. So, you can see that this way we are equivalent to increasing the yield. As for the future, we can continue to improve the farm tools, so that we can continue to increase the yield." Jing Wen said.

Jingwen actually planted extensively in the previous farming level. Before the Tang Dynasty, even in the early Tang Dynasty, agricultural planting was very extensive and did not have much fine management. Now Jingwen hopes to change the thinking of the farmers in the Tang Dynasty and let them cultivate the land carefully. Because of the perfect farming tools and the Turks have been defeated, the cattle and horses on the grassland can also come to the Central Plains to help the people plant the land, so there is no shortage of plowing oxen for the time being. Next, when fiddling with these lands, they can cultivate carefully and increase grain output.

"Good things are really good things! Lord Jingwen is indeed a erudite and talented person. Lord Jingwen's seedling machine and curved plow are no less than Jia Sixi's Qimin skills back then. It seems that maybe in a short time, Lord Jingwen will be able to win the title of Agriculture Saint!" The official of Sinong Temple immediately praised it.

Obviously, anyone who praises this kind of flattery does not require money can speak up. Anyway, as long as Jing Wen is fooled, the Sinong Temple and the Ministry of Industry can work together to produce the seedling machine and the curved plow, which is very helpful to farmers.

"Mr. Jingwen, I will express my gratitude to you on behalf of the farmers in the world. And now there are still a few months before spring plowing. If we produce it now, maybe the people near Chang'an can use this kind of curved plow and seedling machine for this year's spring plowing. In this way, our Chang'an and Guanzhong area will soon have a bumper harvest. And then there will be more land to cultivate, so that my Tang Dynasty's grain can increase a lot of output. In this way, everyone in my Tang Dynasty can have a full meal, and Lord Jingwen is a hero of my Tang Dynasty!" said an official from the Sinong Temple.

Although Jing Wen was happy, he did not forget his thoughts, which was to charge a patent fee.

"By the way, the Ministry of Works and Sinong Temple are responsible for producing curved plows and seeders. I have no objection, but we should talk about the patent fee!" Jing Wen said.
