"Everyone, this is the first batch of fire sickles. It is very convenient and clever fire-making object. But it is relatively simple. If someone thinks it is not good-looking, you can go back and have someone make a bag to put it in. I will provide a small piece of magnet and a small piece of iron, so that it can be sealed with a magnet. If someone doesn't know how to do it, you can ask Changle. You all know what this turquoise is made of, so you need to make it yourself. Also, if you use charcoal to burn the fire with a charcoal, the effect will be better."

When Yang Heng was talking, someone couldn't wait to practice the fire. Although it was just a first practice, it was lit very quickly, and smiles appeared on his face, "It's not simple, not simple, this is great. It's very easy to light the light at night. It won't be out of the light, and you have to wear clothes and walk in the dark." This is what Li Gang said. Maybe there are fewer servants in his family, and some things are not done so conscientiously. If the light is turned off at night and the servants don't know it, it will be very troublesome. Even if the servants know it, it will be very troublesome. It is also very troublesome to find fire at night. In the family of ministers, the lights are usually dim at night.

I dare not put it off. After I get it up, I just need to lift the wick and it will light up. The fire source is also buried with things. Generally, I don’t pick up the fire source in the middle of the night. Most of them are picked up at dawn, and then I cook or something. If the fire source is turned off and the light is turned off, I need to borrow the fire from my neighbor’s house, especially on rainy days, which is even more difficult. Sometimes there are many servants on the street who come out to borrow the fire. With the fire sickle, Lao Li Gang is naturally very happy. He is not happy for himself, but for the entire human being. Just such a small thing allows people to truly have a convenient fire source.

This is a great Confucianism. A great Confucianism must have the pride of a great Confucianism, and a great Confucianism also has the mind of a great Confucianism. They have a broad mind.

For Yuan Tiangang, his gain was that Yang Heng did not lie to him. There was really a tool that was more convenient to watch the starry sky. With this tool, he could better observe the starry sky. Judging some astrological signs may make his astrology further, but it may disappoint him. The so-called astrological signs are not what he thought. Everyone will have a star on their heads, and even the emperor will not hold a star. Perhaps he will become a galaxy naturalist from then on.

In fact, there was not much gain for Xiao Niang and the other three. These things were still far from them, just Changle. Now they are not in power as a housewife in Yang Heng's family, and everything is still in the hands of the housekeeper. Naturally, she was so happy that she was relaxed.

The one who gained the most was Master Sun. He entered the mountains once a few days ago, observed his medicine garden, and even picked some mature medicinal materials. This time he came in purely with Li Gang and Yuan Tiangang. The fire sickle was just a small harvest, but there was no fire sickle. When he went out, he also carried a wooden bow and some fire-induced items, which were placed in a bamboo tube. In fact, Master Sun had long used a bamboo tube with a lid.

"Xuewen, what does it mean to take us to visit this valley?" After everyone came out, Li Gang felt sensitively that Yang Heng must have his intention, rather than simply taking them to visit.

"Well, yes, I must have intentions. Professor Li, you don't think that there is only Confucianism in the knowledge, right? Everything is knowledgeable, such as farming, which is supported by certain knowledge and the experience of old farmers. If pure nerds are allowed to farm, they will starve to death. But with these experienced old farmers, as well as precise weather knowledge, soil knowledge, even fertilizer knowledge, and breeding knowledge, you can increase the yield of grain without starving the world. Therefore, farmers are also a great existence. If the scholars are the first to be inseparable from, what will happen if they are not farmers?"

"What will happen? The scholars don't know how to plant. Although there are farmlands, there are even many. The farmlands that can be cultivated are their tenants. If they don't have these tenants, they might starve to death." Old Li Gang nodded and responded. Although he also has fields at home and there are not many farmers, he has never personally been to the land. He is the same as Li Er, just to show his servants, or even to show God for sacrifices. In fact, what he would plant? It would be good to be able to scatter seeds in the field. Not to mention that this kind of field is also a series of work, such as plowing fields, fat fields, fallow farming, autumn harvest, etc., it would be good if he could tell this procedure. He would be able to push others by himself. This is even more so in other ministers' families. If he leaves the tenants, even

Farmers will also starve to death. For a country, if they leave farmers, who will rely on to farm and who will use to guard the country, it can be said that these things have never been thought of before. Only after visiting Yang Heng's research base did they get this understanding. It turns out that this farmer is a little wronged, but they did not put the farmer second, and even put the farmer last. In their eyes, scholars, farmers, industry and commerce may be scholars, merchants, industry and commerce. You must know that merchants are in an important position in the family of some ministers. Everything they buy is based on money, but they don't know that money is full. If there is no farmers, there will be no food. Without food, they have money and have nowhere to buy it.

"Why is there more fruit wood than grain research?" "Fruit wood, of course, is for eating, and for making wine. You should know that brewing wine will waste a lot of grain. But with these fruit wood, you can use fruits to make wine, and even produce high-colored wines. It not only has the aroma of fruits, but also the strong white wine."

Yang Heng had considered it very long. Perhaps in history, there was no shortage of food during this period, but Yang Heng came. Although the output of grain has increased, people's lifespan and birth rate have also increased a lot. In short, the increase in grain cannot keep up with the increase in food eaters. If you don't consider the problem of food now, and wait until the problem of food appears, it will be too late. You must know that Yang Heng does not have the ability to increase the output of grain exponentially, which is good, but the population will increase exponentially with the increase of medical and health care, especially Li

Second, he still did not follow Yang Heng's advice and let the woman get pregnant after the 18th. He still issued an imperial edict to get married and have children as soon as possible. He would not have thought that the child would also become an avalanche. If Yang Heng saw some women die of dying from childbirth, Yang Heng would not bear it. Therefore, he would popularize medical and health as soon as possible. Even Sun Simiao would do this. Once Yang Heng's reputation as running academy spreads, perhaps Master Sun's apprentice would increase like an avalanche. There would be no good successors in this place, but for the whole Tang Dynasty, there should be no more successors.

"Professor Li, don't ask. I know you want to care about the devil released. In this matter, there are good sides and bad sides, but in short, there are many good sides, and the bad side is targeting foreigners. You won't feel sorry for those foreigners, right? I don't treat them as humans. You should know that when you are strong, they will not be ashamed of them. But once you become weak, they will tear off their hypocritical masks and deal with us fiercely. So for me, I would rather see them extinct than pity them." Yang Heng said ruthlessly. He hated outsiders quite a lot, and he wanted to exterminate all people outside the Tang Dynasty now, and there would be no foreigners bullying the Chinese in the future.

"And that steel, don't you think we need a lot of steel to make weapons, manufacturing tools, and even use them as building materials. Will our Tang Dynasty become stronger in this way?"
