If you want to start spring ploughing again, the first thing you need to do is, of course, to put the broken cylinder back on. In view of the precedent of the broken support column, Lin Sen made some simple improvements to the entire cylinder car this time.

The reason why the column will be broken is mostly caused by the continuous friction with the support shaft in the middle, and the position of the support point contact must not be as smooth as both sides, and the friction generated is naturally not the same, and the wear and tear will naturally be different, and it is inevitable to tilt to one side in the long run.

Although Lin Sen can't make the force on both sides completely consistent, there is a way to reduce this friction a lot, at least the smallest under the current technical conditions, and the things used are also very simple, just put a bearing on each side.

Datang's smelting level at this time, I am afraid that it is difficult to make a completely smooth iron ball, and it is not easy to create a bearing sleeve that can be set up, and the iron ball rolls for a long time under such a large force, and it is also difficult to say how long it can be supported, and the hardness alone is afraid that it is much worse.

But these will naturally not be a problem for Lin Sen, because he can use those birch woods to grow iron birch beads, and the size and shape of the bearing sleeve can also be accurately controlled.

As for the hardness of these wooden balls, there is no need to worry at all, later generations of old Maozi have also used this iron birch wood to make bearings on large ships, the working conditions of that thing are much worse than this simple cylinder car, put it on this cylinder to use, naturally it is easy and pleasant to be competent for this job.

The cylinder car with bearings was quickly installed again, and there was a lot of strength. Then all the dealers looked at Lin Sen with more reverence in their eyes, because after Lin Sen's improvement, the cart rotated much more briskly, and it could be seen just by looking at the much more water speed in the sink.

Lin Sen, who once again leaked his face in front of the villagers, of course he was not complacent, and he was not idle when the farmers were busy continuing to plough and level the land.

He has not forgotten the promise he made to the farmers and to himself, and he must let these farmers who follow him have enough to eat, so now is the time for him to fulfill this promise.

Since the last system upgrade and the ability to control the growth of plants, Lin Sen has been working hard to make crops more abundant, but the system is too strict.

He can manipulate those plants to grow into the way he wants, but the seeds of these crops are planted in the ground, and without his deliberate control, they still grow exactly the same as they were at the beginning, not to mention that the height has not changed, and the yield has not increased at all. This plan to cultivate good seeds could only end in failure in the end.

But now the system has been upgraded again, and this time I picked up the plan again, and the result was naturally very different.

As long as Lin Sen wanted to, not only could the crops he had modified change the way he envisioned, but their seeds would still be able to retain those changes under natural growing conditions. Of course, compared to those plants that are directly transformed, the effect will decay from generation to generation.

This is the practical conclusion that Lin Sen has come to after many experiments and manipulating the rapid growth of generations of seeds.

Of course, after such seeds are planted by the farmers, because of the field management, the fertility of the land and other problems, the yield per mu will definitely not be able to reach the ideal yield when Lin Sen controls the growth, but compared with the existing grain varieties, the improvement is definitely not a little bit.

In short, Lin Sen can finally fulfill one of his long-standing wishes and become a generation of Demon Rice Grandmasters of the Tang Dynasty.

Well, it should be said that there is more than that, because there is not only one type of grain he has transformed, he has taken out several good varieties at once.

These made a group of scientists in later generations spend a lifetime, or even several generations, to come up with a peerless good thing, and they have completed a lot in the wave of Lin Sen's hand, if this is known to the group of sub-scientists in later generations, I don't know if they will vomit blood.

It's just that the farmers who planted these good seeds that will surely set off a big storm in the entire Tang Dynasty in the future don't know what kind of miracles they have sown with their own hands, and it is even a little strange for Lin Sen to ask them to take grain seeds from him.

If it weren't for their consistent trust in Lin Sen, or their near-admiration and blind trust, they were afraid that they would have complained about Lin Sen in their hearts, and this move would be suspected of exploitation and accumulation.

But after Lin Sen announced another news, the little strangeness in their hearts disappeared, and all that was left was full of gratitude, and by the way, Lin Sen really rose to the level of a Buddha in ten thousand families.

Although they have temporarily overcome the current difficulties, and the matter of dealing with Wang Junkuo over there has also been arranged, naturally Li Mu will risk their lives to complete it, but Lin Sen has definitely not forgotten that it is actually those behemoths of the family that caused all this, and these guys are afraid that they are still peeking at the Lin family Zhuangzi and getting rid of him, a figure who may destroy their foundation.

In this case, he must have to spread more seeds, and the more the enemy does not want him to do, the more he must do a good job.

What is the source of the family's hatred for him? Didn't it start with him starting to teach Xi Junmai the knowledge of the brothers.

The Maison feared that when the people became wise, or if they had more ways to learn cultural knowledge, the prestige on which they had relied to grow stronger, and the monopoly on knowledge, would become a thing of the past.

And the imperial examination that was originally used to deal with them is afraid that it will no longer be a simple decoration, and when there are really many poor students in the court, they really have no hope of turning over.

So, after the farmers were busy sowing, Lin Sen gathered everyone together and announced that he would give lectures and teach cultural knowledge to all the school-age children in the Zhuangzi.

This decision can be said to be the result of his careful consideration, after going through so many things, he does not despise the knowledge he has mastered as much as before, this will not only be his most powerful weapon, is the most effective means to fight back against those families, but also the most ardent expectation for his subordinates, representing a brighter and broader future.

By accepting these children from the Zhuangzi, he will not only have more seeds to spread his knowledge, but will also turn the villagers into his most unwavering supporters, which can also be regarded as a reward for the loyalty they have realized before.

And the performance of the bankers also proves that he has achieved these goals. Because after hearing the news that he announced the acceptance of students, these farmers, who had never bent their backs even in the face of the most difficult life difficulties and the most vicious enemies, did not hesitate to kneel down and express their most sincere gratitude with the most solemn etiquette.

And such a heavy scene also stirred Lin Sen's heart, and also made him secretly determined that he must teach these children well, so as not to disappoint the villagers, and to be worthy of his conscience.
