When this calms down, all the anguish of a person comes out. In this world, no one really understands himself, even Yao Qisheng Li Guangdi and other top elites of this era, he is still not with his ideological level, and he slept in this beautiful villa by the sea for a night, still did not get rid of the discomfort in his heart, so he boarded the carriage early in the morning and returned to Fujian, and entered the scientific research base set up for two and a half years, that is, those few real yàn rooms to fiddle with new objects. Only when facing some common items in later generations and machinery close to later generations will Geng Jingzhong be truly comfortable. In this R&D base, in fact, there are many things in it that Geng Jingzhong put forward ideas for these researchers to do practical research, such as the rickshaw that just emerged in the New Year in Houyu Port is a typical example.

Although the carriage runs smoothly on this concrete road, it produces a considerable amount of horse manure from time to time on the street, especially in the commercial area of this port, and none of the merchants who come here are short of money, so it is normal to go out and take a carriage. If you want to kill those officials, you would prefer to sit in a sedan chair, but the sedan chair has been banned by Geng Jingzhong, and officials in Fujian, no matter who they are, are not allowed to sit in a sedan chair. As a result, horse-drawn carriages became more popular, and with it, horse manure appeared on the streets of the city, causing headaches for the city's sanitation workers.

Rickshaw, of course, this is Geng Jingzhong's own name. Nowadays, people call this kind of car a rickshaw. The latest invention in the scientific research base can be regarded as the invention of pneumatic tires. One of the things that has to be said is the use of rubber. Geng Jingzhong, who had been thinking about the improvement of the gun truck for a long time, could not have considered the problem of tires. And the production of zuò tires is inseparable from rubber. Although the wheels of horse-drawn carriages are still wooden, and rubber tires have not yet become popular, as rubber trees are introduced and begin to slowly expand their planting, the convenience of wheels will usher in a huge change in the future.

Regarding rubber trees, at the end of the previous year, Spanish merchants came to Fujian from the Americas, and that was Geng Jingzhong when he asked his subordinates to buy saltpeter from the Spaniards, and Geng Jingzhong paid a lot of money to ask the Spanish merchants to buy it, and sure enough. Driven by huge profits, it took half a year for Spanish merchants to finally transport the rubber trees. Twelve merchant ships brought in a total of 600 rubber trees, but only 450 survived, but fortunately, the climate in Fujian was more suitable for the growth of rubber trees, so a new species officially took root in China. In addition to these hundreds of rubber trees, Spanish businessmen also brought in a large number of rubber tree seeds, all of which were planted, and no less than 100,000 rubber tree seedlings have been obtained since last year. In the future, after these saplings are transplanted. There is not much place to plant in Fujian, so it will be put on the Luzon Island, where there is still more land, and the climate there is more suitable for the growth of rubber trees.

In the prehistoric period of rubber, it was simply mined and exploited only by the Indians of South America. In the beginning, rubber may have been used as a treasure or an extremely valuable item. South American Indians call the rubber tree "the weeping tree", and if you carefully cut the bark, the milky white gum sap will slowly flow out. However, Geng Jingzhong knows very well that the main raw material for making zuò rubber is natural rubber, which is made by solidifying and drying the latex that flows out of rubber trees when they tap rubber. Natural rubber because of its strong elasticity and good insulation, plasticity, water and air insulation, tensile resistance

and wear-resistant, it has been widely used in industry, national defense, transportation, medicine and health fields and daily life in later generations, and has a wide range of uses.

Oil from rubber tree seeds is also used as a raw material for paint and soap. At the same time, rubber husks can be used to make high-quality fibers, as well as activated carbon, furfural, etc. Of course, it doesn't have that level now, and it can't be used, but as for the seeds, Geng Jingzhong is reluctant to take them to extract oil, and he can still count on these rubber tree seeds to expand the rubber plantation. The more than 100 dead rubber tree trunks, Geng Jingzhong did not waste, after all, it is a wood that has never appeared in China, this kind of wood also has some advantages, such as light wood quality, beautiful patterns, good processing performance or something, the production of zuò furniture is quite beautiful, not much worse than those precious wood.

After the rubber has it, Geng Jingzhong also participated in the development of a period of time, although he has not studied the rubber such a physical object, but the victory is rich in theory, to the later development of the workers put forward the accurate research and development direction. This pneumatic tire is the most direct target, and now the tires on the rickshaw are the finished products that have been successfully developed, but now the tires made every month can be supplied to the 20 rickshaws in Houyu Port in addition to the artillery division's artillery trucks, and no more, there will be no more, after all, there are only more than 400 trees here. Originally, the direct use of rubber to make zuò tires, the wear is quite strict, but Geng Jingzhong's chemistry over the years is not in vain, after adding a certain proportion of carbon black to the rubber, the performance of the tire has been greatly improved, and it has become very wear-resistant. However, although the tires used today are pneumatic tires, they are still incomparable with the tires of later generations. It can be said that it is not a level at all, and now this tire can only be regarded as a relatively rudimentary tire.

Anyway, the tire thing is solved, and this is the hardest part. Other frames and so on can be done by themselves, anyway, the overall structure is so simple. The most important thing is that the tires are the pair of wheels, which are also made by Geng Jingzhong with reference to the experience of later generations, which is much easier than the development of chemical products - tires. In this way, two wheels, tires, and a team of bearings in the middle, then the main structure is complete. Finally, add a seat frame on top and you're done.

With these 20 rickshaws running inside and outside the Monkey Island Port, it has reduced the number of carriages in and out. When the rickshaw came out, it caused a sensation in the port of Houyu, in this golden port business district, there is no shortage of rich people, everyone is vying to experience, so that the drivers feel unbearable. From morning to night, it took a whole day for more than 1,000 people here to experience it. It was tiring, but it was very rewarding, because in that single day, they had earned what they had been paid for a month. However, this is also the first day, and although I made a lot of money in the following days, after the people slowly got acquainted with it, it was no longer as crazy as at the beginning.

There are rickshaws, but after all, they can't be seen in the 21st century, and what Geng Jingzhong wants is the most common means of transportation in later generations - bicycles. The technical content of the bicycle is only a part more than that of the rickshaw, and with the drawings drawn by Geng Jingzhong, it is not difficult for the craftsmen to make the frame of the bicycle by hand, but it cannot be made on a large scale like later generations.

Historically, bicycles were still a thing of the past until the end of the eighteenth century, in 1790, when a Frenchman named Sifrac felt that the road was narrow and there were so many pedestrians, so he thought that he could change the structure of the carriage. So he conceived the idea of cutting the carriage in half, turning the four wheels into two wheels at the front and rear, and after a year of practice, he really made the world's first bicycle. Although the earliest bicycle was made of wood, it had a relatively simple structure, with neither a drive nor a steering device, and the rider had to push his feet and move the bike when changing direction. Even so, when Sifrak rode the bike for a ride around the park, those present were amazed and amazed.

Later, in Germany, there was a forester named Dres, who walked every day from one grove in the east of the village to another in the west of the village, year after year. He thought: Isn't it chic if people sit in a car, stop and go, and do whatever they want? Dresses began to make zuò wood-wheeled cars, which looked similar to those made by Sifrak. However, a handlebar was added to the front wheel to change the direction of travel. However, when riding, you still need to use both feet to step on the ground one at a time to push the bike forward. When Dresse rode out for a test, he was ridiculed by many people along the way. Still, he loves his "cute pony bike". Once, when Dresse was riding a cart, the coachman laughed at him and said that his car was slow, so he said to the coachman, "Believe it or not, my cart is faster than yours," and the two of them made a bet. The journey was a round trip from the east of the village to the west of the village, and as a result, Dresses was more than an hour faster than the coachman.

A few decades later, Macmillan, a blacksmith in England, got a worn-out "cute little pony". He attached a crank to the axle of the rear wheel, and then connected the crank with the front pedal with a connecting rod, and the front and rear wheels were made of iron, the front wheel was large, and the rear wheel was small. When the cyclist presses the pedals, the bike moves itself and runs forward. He was caught by the police and fined for this. He was charged with "savage cycling". Later, the French father and son Michaud, who were originally employed as carriage repairmen, installed rotating pedal plates on the front wheels; The saddle of the bike rests on the front wheel, so unless you are particularly skilled at riding, you will not be able to hold the handlebars and fall off the bike. They gave the two-wheeler the nickname "bicycle" and it was exhibited at the Paris Exposition in 1867 to an eye-opener for the audience.

The bicycle that Geng Jingzhong wanted to imitate in the scientific research base is a common version in later generations, which is the final result of hundreds of years of development. Geng Jingzhong wanted to create this thing into this world in advance, which can be regarded as another precedent.
