"Everyone, this is the first batch of fire sickles, very convenient, very dexterous a kind of fire-making things, but relatively simple, if someone dislikes it is not good-looking, you can go back and let people make a bag to put it up, I will provide a small piece of magnet here, and a small piece of iron, so that you can use a magnet to seal, if someone will not, you can find Changle to ask, and this velvet, you all know what the road is made of, then you need to do it yourself, and, if you use the hemp pole to burn into charcoal to start the fire, The effect will be even better. ”

When Yang Heng was talking, some people couldn't wait to practice the fire, although it was the first practice, but it was also burning quickly, and a smile appeared on their faces, "It's not simple, it's not simple, it's very simple to get up at night and light the lights, the lights won't go out, and you have to walk in the dark." "This is what Li Gang said, maybe there are fewer people in his family, some things are not done so conscientiously, if the lamp is extinguished at night, the next person does not know the way, it will be very troublesome, that is, the next person knows the road, it is also very troublesome to find a fire at night, in the ministers' homes, the general lights are dimmed at night, but they dare not go out, when they get up, as long as the wick is picked, it will be lit up, and the fire source is also buried with something, generally not in the middle of the night to pick the fire source, most of them are picked up at dawn, Then what is cooking or what, if the fire source is extinguished, and the light is also extinguished, then you need to go to the neighbor's house to borrow the fire, especially in rainy days, it is even more difficult, sometimes there will be a lot of people on the street who come out to borrow the fire, this has a fire sickle, Lao Li Gang is naturally very happy. He's not happy for himself. It's about rejoicing in humanity as a whole. It's just such a small thing, so that people really have a convenient fire source.

This is the Great Confucian, the Great Confucianism must have the pride of the Great Confucian, and the Great Confucianism also has the mind of the Great Confucian, and they have the world in mind.

For Yuan Tiangang, what he gained was that he found that Yang Heng did not lie to him, and there was really a more convenient tool for watching the starry sky, with this kind of tool, it could allow him to observe the starry sky better. Judging some astrological signs may make his astrology go further, but maybe it will disappoint him, the so-called astrological phenomena are not what he thinks, everyone will have a star on their heads, even the emperor will not carry a star, maybe he will transform into a galactic naturalist from now on.

For Xiaoniang and the other three, there is actually not much gain, these things are still far away from them, that is, Changle. Now in Yang Heng's family, he is not in power as a housewife, and everything is still in the hands of the housekeeper. Naturally, she was happy.

And the most unharvested is Sun Daochang, he entered the mountains once in a few days, observed his medicine garden, and even picked some mature medicinal materials, this time he came in purely to accompany Li Gang and Yuan Tiangang, the fire sickle is just a small harvest, that is, there is no fire sickle, he also carries a bow for drilling wood when he goes out, and there are some items that ignite the fire, which are placed in a bamboo tube, in fact, Sun Daochang has long used a bamboo tube with a lid.

"Xuewen, what do you mean by you taking us to visit this valley?" When everyone came out, Li Gang sensitively felt that Yang Heng must have his intentions, not simply to take them to visit.

"Well, yes, I must have a good intention, Professor Li, you don't think that there is only Confucianism in learning now, everything is knowledge, such as farming, which is supported by a certain amount of knowledge and the experience of old farmers, if you let pure nerds farm, they will starve to death, but with these experienced old farmers, as well as accurate weather knowledge, soil knowledge, and even fertilizer knowledge, and breeding knowledge, you can increase the yield of food, and not let the world starve, Therefore, the peasant is also a great existence, and the first thing he can't do without is the farmer, what will happen if there is no farmer? ”

"What will happen, the scholars don't know how to plant, although there is farmland, and there is even a lot of it, but the tenant farmers who can cultivate it are all under their control, and if it were not for these tenant farmers, they might starve to death." Old Li Gang nodded and replied, although he also has a field at home, and there are not many households, but he has never gone to the ground in person, even if he goes to the ground, it is the same as Li Er, that is, to make a show for the next people, and even for the sake of sacrifice for God to see, in fact, what will he plant, it would be good to be able to scatter the seeds in the ground, not to mention that this kind of field is also a series of work, what kind of ploughing, fertilizing, fallow, autumn harvest and other things, he is able to say this procedure It is not bad, push others by himself, This is especially true in the families of other ministers, if they leave the tenant farmers, or even the farmers, they will starve to death, and for a country, if they leave the farmers, who to rely on to farm, who to use to guard the country, it can be said that these things have never been thought of by the old Li Gang before, only this time after visiting Yang Heng's research base, I have this understanding, it turns out that this farmer is in the second place, and they are a little aggrieved, but they do not put the farmer in the second place, and even put the farmer in the last place, In their eyes, they may be scholars, merchants, workers and peasants, you must know that the Taoist merchants are in an important position in the families of some ministers, and everything they do depends on money to buy, but they don't know the Tao of the Mountains, money is not full, if there is no agriculture, there is no food, without food, they have money and nowhere to buy.

"And what about fruit trees, why will there be more research than food?" "Fruit trees, naturally for eating, and for winemaking, you must know that Ludao winemaking will waste a lot of food, but with these fruit trees, you can use fruits to make wine, and you can even make a high degree of wine with color, which will not only have the fragrance of fruits, but also the intensity of liquor."

To say that Yang Heng is thinking very far, maybe in history, this period is not short of food, but Yang Heng came, although the output of food has increased, but people's life expectancy, and the birth rate has also increased a lot, in short, the increase in food, can not catch up with the increase in the number of people who eat food, if you don't consider the problem of food now, and wait for the food problem to appear, then consider, it will be too late, you must know that Yang Heng has no ability to double the output of food, it would be good to be able to increase a few percent, but the population, With the improvement of medical and health care, it will increase exponentially, especially Li Er, who still did not follow Yang Heng's advice, let the woman get pregnant after eighteen, or issued a holy decree to marry and give birth as soon as possible, he would not have thought that this child would also become an avalanche state increase, if Yang Heng watched some women die in childbirth, Yang Heng would not be able to bear it, so he would popularize medical and health care as soon as possible, even Sun Simiao would also do this, when Yang Heng's reputation for running a college spread, Maybe Sun Daochang's apprentices will also increase like an avalanche, and there are no good heirs in this place, but in terms of the whole Tang Dynasty, there are not many heirs.

"Professor Li, don't ask, I know that you want to care about the devil who is released, in this matter, there is naturally a good side and a bad side, but in the end, there are many good sides, few bad sides, and the bad side is for foreigners, you won't pity those foreigners, I don't treat them as people, you must know that when you are strong, they will not be cheeky to pat the horse, but once you are weak, they will tear off their hypocritical masks, Come and deal with us fiercely, so in my opinion, I would rather see them exterminated than have mercy on them. Yang Heng said cruel things directly, he hated outsiders quite a lot, and he couldn't wait to exterminate all the people except Datang now, and there would be no foreigners bullying the Chinese in the future.

"And that steel, don't you think that we need a lot of steel to make weapons, make tools, and even use it as a building material, so that our Datang will be more powerful?"

Yang Heng's words made Li Gang fall into deep contemplation, obviously feeling that Yang Heng might be some fallacy when he said this, but he couldn't refute him. (To be continued......)
