A mortar shell is actually not difficult to make, of course, as long as the material is passed. In ancient times, it was difficult to train good steel because of the temperature. This Liu Zhang can refine, so naturally he can also have high-quality steel. The second is that delicate things can be stronger, such as gears. The gears made of bronze seem to be strong, but they are very wear-resistant, and the durability effect is also very poor.

"The production of tricycles is already very large, but it still feels very insufficient." This point is also helpless, the chain gear does not have the help of machinery, but it needs to be made one by one, and finally it needs to be polished. These are very time-consuming, and if you have mechanical power later, you can save a lot of trouble.

Liu Zhang nodded and said: "This time I asked Wen He to come and study the steam engine with Huang Laozhang, just to solve this matter, and then our industrial reform can begin." In the future, when the steam engine is used to generate electricity, the era of electricity can begin. "After all, we still need electricity, which is the most convenient source of energy.

Fa Zheng was a little confused when he said this thing, no matter how much they learned to be rich and five cars, they couldn't understand this kind of thing. However, the steam engine is not complicated, but the utilization rate is very poor. However, it is still mechanical power, if it is possible, Liu Zhang also wants an internal combustion engine, but this is really to think about. Without the cumulative development of technology, this is almost impossible. When you die of old age, you may be able to see the internal combustion engine??

The car was moving, and by noon, it was almost there. At the foot of the hill there were many more houses, and they were lined up into the distance. It can be seen that this has become an experimental base, and the seat on the slope of the mountain is the residence of Huang Laozhang. There is also an ecological park not far away, and the water resources here are not polluted, which Liu Zhang has explained before, and they will pay attention to these themselves.

Huang Chengyan was already waiting outside, and he had already known about Liu Zhang's arrival in advance. It's not just Liu Zhang who is here today, but also a large group of Liu Zhang's ladies behind him. After getting out of the carriage, Huang Chengyan greeted him: "The lord ......" Looking at Liu Zhang, Fa Zheng and others, Huang Chengyan could see that Liu Zhang attached great importance to the steam engine.

Liu Zhang looked at Huang Chengyan, who was in good spirits, with a smile: "Uncle Huang has a good complexion, I have something important to do this time." Remember the steam engine you talked about last time? This time I've already brought the materials, and we just need to study it to make it, and then the car won't need to be started at all. "The bus made of the steam engine is estimated to be difficult to brake, and it is better to make a train. But there is no way now, if you can make a big car, you can make a big car first.

Huang Chengyan couldn't help but smile bitterly and said: "I've been waiting for the arrival of the lord for a long time, since the lord said it that day, I have been thinking about it day and night." "I used to think that the wooden ox and the horse were very powerful, but after all, I was limited by the material. The transportation capacity cannot compete with that of a tricycle, let alone be strong and long-lasting.

Liu Zhang pointed to Jia Xu on the side and said: "This one is not just a wise man, he is also a scientist. With his help, the steam engine should be easy to make. I've already drawn the construction diagram, and you can watch it work. "Liu Zhang's arrival is just an auxiliary guide, and he will definitely not participate in this kind of thing. With the construction diagram, there are theorists, and they should practice. In the future, when they have their own experience in making their own, they can pass it on to their apprentices or teach their students, which is a valuable asset. After all, there is no need for Liu Zhang to learn this thing, after all, he is a big man who has seen an internal combustion engine......

Liu Zhang, who was talking, took a look at the nearby workshop, where many craftsmen were discussing molds and how to make production more convenient. Liu Zhang thinks this atmosphere is not bad, and he should give money to encourage him. said to Fa Zheng on the side: "Filial piety must be encouraged in the future, as long as you make achievements, you can only reward them." "If you have money and willful rewards, Liu Zhang will definitely improve the status of scientific and technological personnel in his country in the future.

After looking at it for a while, Liu Zhang handed over the drawings to them, and the two of them immediately took them to study. Seeing that they were busy, Liu Zhang took a few people to the house on the mountain to have a look. It's actually quite well built, with a path winding up to the mountainside. In the winter, there is still a lot of snow here, and it is not at all like in later generations when it was a little southerly, and it was difficult to see such a thing as snow. The global greenhouse effect was basically not reflected in ancient times, after all, it is still the end of the Xiaoice River.

The breeze is gentle in the bamboo forest, and when you arrive here, you will feel the cool smell. I don't know if I have picked bamboo shoots this year, but Liu Zhang still likes wild ingredients. I don't think there are many mosquitoes here, probably because there are no pools nearby. It would be nice to get a hammock and take a nap here.

Liu Zhang, a craftsman from Chang'an, also brought a batch of them, who came to make mortar shells. Samples of this thing have been made in Chang'an before, and the experimental effect is not satisfactory. However, Liu Zhang felt that he could actually add a little more explosives to it, and it would be the most suitable one.

After all, this time he hit Sun Ce, and Liu Zhang felt that it was definitely better to use mortars than earth artillery. Don't they like moats, don't they like to defend? This time, Liu Zhang saw how they defended, what else did the two counties want? This time, I will kill them directly, what Jiangdong generations belong to the Sun family?

When I came to my own accommodation, it was well built, especially since the floor was separated from the ground. Taking off their shoes and stepping on the wooden plank, looking at the bamboo forest in the distance, these people enjoyed much more than they would have enjoyed. Let Zhang Ren and the others go hunting, Liu Zhang is here waiting for Wang Yi and their arrival.

I built a small courtyard on the mountain, leaning against the small door of the house, where there are comfortable tatami mats. Obviously, tatami mats are things from the Han Dynasty, but later with more comfortable beds, the Chinese people didn't need this thing. I don't know why I'm happy when a small island nation gets this kind of thing......

Thinking about it, Liu Zhang fell asleep, there didn't seem to be any Japanese robbers here in the Three Kingdoms era, right? Of course, Liu Zhang was not in Qingzhou, and even if he came, Liu Zhang was not clear. But I heard that they will often rob near Qingzhou? During the reign of Emperor Guangwu, they were recognized as the Great Han State, and they were also awarded the Golden Seal and Purple Ribbon.

Wait until later...... Thinking about Liu Zhang, he fell asleep, and when he woke up, Liu Zhang was covered with a quilt. glanced at Zhen Mi sitting not far away, she was making tea in front of her, it seemed that she was painting? When Liu Zhang got up, she heard a voice: "The general is awake?" As he spoke, he got up and came over.

Liu Zhang said casually: "Are you painting? She got up and ran over, and sure enough, she was painting. The content seems to be the way he sleeps: "What about them? Why don't you go shopping with them? Liu Zhang can't see the reason for this kind of ink painting, and he can't do this kind of thing himself, but there should be no problem teaching her?

"The concubine is weak, and she is a little tired when she goes up to the mountain, so she will follow her sister and them to play tomorrow." She has just arrived here, and her body is not as good as Cao Hua. In the past, I was basically at home, and I didn't have to walk. After exercising for a while, I felt that my body was no longer good.

Liu Zhang glanced at the painting and said, "You can't do this, you have to exercise more." I'll teach you a new level of drawing, and you'll see if you can learn it, it's definitely more fun than this. "Sketching is actually realistic, although Liu Zhang can't draw so well, it's okay to simply draw an anime avatar.

Take out your pen and spread the paper casually: "This method is called sketching, and its function is to be realistic." Saying that, Liu Zhang asked her to sit beside him, and glanced at Zhen Mi beside him in the distance, and Liu Zhang began to paint. This beautiful cheek is easy to remember, and you can sketch it out almost without looking at it.

Zhen Mi was really surprised, she could see that Liu Zhang was not a master, but she still had a good sense of painting. At least this cheek and appearance are very similar, with the outline of the eyes, although a little out of shape, but in general it is still very similar. It can be seen that Liu Zhang doesn't know a lot, but the things he draws like this are still very beautiful.

"Can you learn it?" Liu Zhang is really not proficient in this, but Zhen Mi feels that it is not bad and barely has a human appearance.

Zhen Mi smiled lightly: "The general knows a lot of things, not only can cook, but also paint?" I heard Sister Cai Yan say that the general will also chant poems against him. From Cai Yan, she listened to a lot of poems made by Liu Zhang, and each one sounded beautiful. But is that really what the general did? Cai Yan and the others were very sure, which made Zhen Mi feel that this general was very different.

Liu Zhang is quite embarrassed, he doesn't really know so much, a lot of life has taught him: "I told you to paint in this way in the future, so that you can look very beautiful." The way I used to draw was very bad, and I felt so ugly when I passed it on. ”

Liu Zhang only remembers to start from one point and slowly construct the entire outline. After teaching her for a while, Liu Zhang was ready to go out to see what the girls were doing. When he went out, Liu Zhang found that the group of people were picking fruits on the edge of the pond not far away, Ma Yunlu, Lu Lingqi and Zhu Rong, three people holding harpoons made of bamboo, as if they were ready to spear fish......

When Liu Zhang came down, Wang Yi and others also saw it, Wu Yi took out the freshly washed fruit and handed it to Liu Zhang: "You can go around casually, I'll go to the ...... of spearfishing" Liu Zhang also likes the process of catching things, but he can't shoot arrows anymore.

Ma Yunlu and the three of them had a lot of fun, and after such a while, four or five fish had already been inserted. There are a lot of people at night, and those gang of martial artists can eat thieves, so it doesn't matter if you catch a little more. Obviously, Liu Zhang is not as powerful as these girls, but he enjoys it.

Farther away, Ma Chao and Zhang Ren had already drunk, and there was a large army around them, so they didn't have to worry about anything at all. This is also a rare leisure for them who have been fighting all year round. There is no restriction on drinking, and there is no war.
