Chapter 977: For the sake of future generations, we must continue to work hard.

After Luo Chong handed over the development task, Lin Fei began to prepare the R&D team. It took a day to assign all the research groups arranged by Luo Chong to responsible persons, and to clarify who was in charge of each group and how many members there were.

After everyone gathered, Luo Chong gave them another big class, explaining the relationship between pressure and pressure, as well as the theoretical knowledge of liquid transmission force amplification that he had previously taught, which also opened their eyes. Two

days later, Luo Chong's personal guards also sent his mechanical models and drawings from home, and then explained them in more detail. It took a full week to teach these people.

However, the content of this class was more detailed, and it was conducted in groups, such as the working principle of the plunger pump, the conversion of force, etc. How big a plunger pump can meet the weight of a machine.

As for the team responsible for the body and mechanical manufacturing, Luo Chong mainly talked to them about levers, counterweights, center of gravity and other issues. For example, a machine like an excavator has a large mechanical arm installed on the side, and the bucket at the top of the mechanical arm also has to carry heavy objects. If the other side of the body is not counterweighted, the car will definitely be overturned. Therefore, knowledge of counterweights, center of gravity, levers, etc. has become a top priority for the design of the body.

The same is true for loaders, which are also vehicles with a serious center of gravity offset. It is definitely not possible without counterweights.

Fortunately, Luo Chong made the style models of these machines based on his memories of his previous life, which can give everyone a clear reference and save everyone from many detours.

Their work is tedious, but fortunately, the purpose is clear. Luo Chong has already put forward all the indicators and requirements. They only need to complete the requirements within their scope of work.

After spending half a month in Xingang County, Luo Chong turned to the comprehensive research institute on the island in the center of the lake, and then handed over the development tasks of hydraulic oil and rubber tires.

These two are not a big problem. According to Luo Chong, if we collect all the existing vegetable oil samples in the Han tribe and then conduct experiments on the proportion of the hydraulic oil, we can always make a similar hydraulic oil. This is not bragging. Even modern hydraulic oil is mainly formulated with vegetable oil. Luo Chong does not require it to be advanced. It can be used anyway.

As for rubber tires, the Comprehensive Research Institute has already had experience. They have made hollow tires for bicycles before, but they used Eucommia gum at that time, and this time they replaced it with rubber. Since the Han tribe began to vigorously support the Tang tribe, they also purchased a lot of rubber from there.

Rubber is currently only purchased by the Han tribe. It is useless for others to take it, so the price can be set by the Han tribe, so the price is not very high. This is the advantage of the buyer's market. In other words, no matter how low the Han tribe offers, they have to sell it. If they don't sell it, no one else will buy it.

However, the consumption this time is still very large, especially for loaders and tractors, the wheels are very large, and the diameter is taller than a person, but the power research institute has not yet given specific data, so they can't make molds.

The last item is about the production of hydraulic hoses. This thing is very important. Otherwise, if the quality is not up to standard, there is a high possibility of pipe bursting.

"Leader, my idea is to add a non-elastic wrapping layer on the outside of the rubber hose, just like the air pipe of the air compressor, like the canvas on the outside of the air pipe, to limit the expansion of the rubber hose. Do you think this will work?" A member of the rubber team told Luo Chong about his research ideas.

"Adding expansion restrictions is certain, but canvas is not good. Canvas is not strong enough. That is a hydraulic hose of engineering machinery. It has to bear a force unit based on tons. Several tons of force are transmitted by the hydraulic oil inside. If canvas is used, it will definitely burst." Luo Chong immediately shook his head and rejected it.

"Then, what should we use? We can't wrap it with iron wire, that will only make the tube into a sausage." The person in charge of the rubber team said in embarrassment.

"Well, iron wire cannot be used, but if the iron wire is denser, it can be replaced with iron cloth. This should be about the same. Yes, let's do it this way.

"I'll ask Xingang County to try to make some iron cloth, and then you will try to make a three-layer rubber tube, with three layers inside and outside, two layers of rubber and one layer of iron cloth, and finally a layer of canvas on the outside, so that the liquid pressure inside can be restrained.

"You, you should prepare the hydraulic oil first, and wait for the specific plan and materials to come, and then you can do the rest."

Luo Chong left directly after speaking, and then began to run back and forth between his home in Xingang County and Hanyang County. Construction machinery is definitely a big project, and Luo Chong is very concerned about it. Although he doesn't do much work when he goes there, some ideas he provides can often help people avoid many detours.

In this way, fifty days passed in a flash. In the middle of October of the first year of Da Ming, the season had reached the end of autumn and the beginning of winter. After finishing the important matters such as autumn harvest and winter storage in various places, it was finally the 100th birthday of the third and fourth sons of Luo Chong's family, and he, as a father, began to prepare a banquet.

When the child was born, he had promised those who gave gifts that he would have a banquet to entertain them when the child was 100 days old. It happened to be the beginning of the slack season after the autumn harvest and winter storage. He was also going to gather the county governors under his command to keep in touch with each other and summarize this year's work and the outlook for next year, which could be regarded as a summary of the three quarters of production.

Many people came to drink this time, and they did not come empty-handed, but the things they brought were not expensive, mostly local specialties and some food from various places. It was the end of autumn and the beginning of winter, so it was naturally the season for nourishing the body. Luo Chong specially prepared several tables of hot pot to entertain them. Everyone liked to eat this, mainly because they had joined the Han tribe for a long time in recent years, and everyone had become addicted to chili peppers and were not used to something without spicy.

At the table, Luo Chong raised his glass and said to everyone, "Everyone has done a good job this year. I have read the memorials sent from various places. A lot of grain has been stored, the granaries have been built very solidly, and some infrastructure has been implemented relatively well. However, this is not enough. Everyone must continue to work hard, not for us, but for our descendants."

Luo Chong talked about the construction of various places in the Han tribe, and suddenly turned the topic back to the children. Originally, this banquet was ostensibly to celebrate the addition of a new member to the leader's family, so he continued to talk.

"Since the establishment and growth of the Han tribe, it has accepted many tribal clans and recruited wild people for education. The population has increased day by day. Fortunately, all the wise ministers have worked together to make the people have their own houses, the farmers have their own fields, and the livestock and poultry are fighting in front of and behind the houses.

"Now that life is stable, the family is not lacking in food and clothing. In addition, with the guidance of policies, the people will naturally reproduce a large number of offspring. Everyone present here has added a lot of new members to their families, right?"

Hearing this, everyone smiled and nodded. Having children is a good thing, and it is supported by the policy. There is nothing to be ashamed of.

Luo Chong has had four children over the years, and this is because he currently has only two women. However, the clans below are different, especially those with official positions. In the past clan tribal era, they were more powerful than ordinary tribal leaders. In short, they are the small group of people with priority mating rights. How could they have fewer children?

"Hehe, we have indeed added a lot of offspring in these years. The fewest are six or seven, and the most are more than ten. In this regard, we have caught up with the leader. Leader, you can't do this. You are younger than us. You need to work harder."

Dali and Luo Chong, who came from Xingang County, are considered relatives. They are the earliest group of people in the Han tribe and speak more boldly. When they heard Luo Chong talking about the descendants, they immediately took over the conversation.

"Oh, of course I know you have had many children. You have so many that you can't even remember them all, right?" Luo Chong didn't respond to Dali's words, but continued to point at them.

After hearing this, everyone laughed again. The Han tribe now is not just about having many children. The key is that the survival rate of children born now is high. People's lives have stabilized and they have started to settle down and farm, so many things can develop normally.

For example, the Maternal and Child Health Hospital, which specializes in childbirth, has reduced the risk of childbirth. In addition, the Han tribe now has guaranteed clothing and food. Men don't need to go hunting anymore, and women don't need to go out to gather. They won't encounter any dangers. They can raise their children well by managing the family business, so the survival rate of children is also high.

"Don't giggle here. I know you have given birth to many children, but the people under your rule have also given birth to many children in recent years. You should see the trend. When this generation grows up, the population of the Han tribe will explode. At that time, there will be higher requirements for farmland, housing, and other aspects."

Everyone nodded seriously after hearing this. The leader was right. The population of the Han tribe has indeed exploded in recent years, but these people have not yet become a demographic dividend. It will take at least fifteen years for these people to show their value.

When these children grow up and join the society, set up their own families, and start to have children, the Han tribe can really enjoy the dividends brought by this huge population.

"What the leader said is right. In recent years, many children have indeed been born in the families of the people. Some of the older counties have even more. For example, the earliest established counties in Hanyang County, Fumaguan County, Danshan County, and Matan County, even if there is only one woman in the family, there are an average of more than five children per household over the years.

"Further east, there are also many children born in Liuyang County. Our Dongxin County and Weishan County were built in the same batch, and now it is almost the same. There are also many county towns in Ruyang County. The two newly established counties have fewer children, and the newly established Nanzhang County and Muye County have even fewer. But it's just a matter of time,"

Jing Yan of Dongxin County said while eating mutton at the dinner table.

Luo Chong nodded. He knew about this situation, so he listened to him continue.

"So for the sake of these children who are about to grow up, we have to continue working hard. When they grow up, want to be independent, get married and have children, our land and housing will have to increase significantly. It will be a bit late to open up wasteland at that time. It is better for us to work hard now so that when they take over in the future, it will be cultivated land.

"Also, we have to store more food. These children will be the main source of food in the future, but they don't produce much, so we have to raise them in this generation."

When She Xin of Liuyang County heard Luo Chong talking about food, he immediately had something to say.

"Chief, speaking of food, I think you mobilized too much food for this expedition to the cannibal tribe in the north. It's the annual rations for 30,000 people, but the troops you sent out are only about 2,000 people. They can't eat that much. How can a garrison have more food than what was needed when the troops were sent to Qiongzhou?"

"Yes, yes, I'm also wondering about this question. Once the food was transported away, I felt empty all of a sudden. Originally, we were going to implement the storage plan for the big life year this year. Seeing so much food in the granary, I felt at ease. As a result, most of it was transported away, and the warehouse was almost empty." Lu Guangzhu of Weishan County also said.

They were in charge of the two largest water transport docks in the inland area of ​​the Han tribe, one in Liuyang County and the other in Weishan County. The fleet that went out to the expedition went from there, so they naturally knew very well how much food was transported away.

"There are reasons for transporting food. How can conquering Zhudao be the same as conquering cannibals? Zhudao has 100,000 people, and they can farm by themselves, so they have a stable source of food.

"You see, I have six garrisons stationed in Qiongzhou. In fact, the food needed every year does not need to be transported from us. The taxes collected from the local area can support these soldiers.

"Besides, the political environment of Zhudao is different. By conquering Zhudao, we can obtain a large number of citizens, people who are good at production, and the resources on the land of Qiongzhou Island. We can even occupy an important place overseas, especially the Qiongzhou Strait, which is a strategic place that is most suitable for use as a military port.

"But the situation is different with the cannibals in the north. As the saying goes, those who are not of my kind must have different hearts. No matter what the Xin tribe and Zhudao were like in the past, they were human beings like us, clan tribes, but the cannibals in the north were different. Not to mention that those huge red-haired giant apes were basically monsters, even those totem warriors who fed on humans could not be regarded as the same species as us, so why did the Han tribe conquer them?

"Of course, it is to completely resolve the threat from the north, clear the obstacles for our Han tribe to continue to expand its territory, and completely exterminate the giant monsters coming from the snowy mountains. What benefits can our Han tribe gain from this war? That is a large number of cannibal slaves and the people rescued from there. The food I want is used to feed these slaves." Luo Chong couldn't help but explain to everyone.
