City parks, for people 2,000 years from now, will certainly be the most common urban public foundation.

However, in the Qin Dynasty, Li Yang's proposal to build a city park was of great significance.

It is important to know that the city park is not only one of the main contents of urban construction, but also an important part of the urban ecosystem and urban landscape, and it is also a place to meet the leisure needs of urban residents, provide rest, sightseeing, exercise, communication, and hold various collective cultural activities.

In other words, the definition of a park is a place for people to play and relax in public activities.

Its greatest significance lies in the "gong" character of the park.

You must know that in ancient times, there was no garden for the public to rest and play, only the garden of the official family.

It can be said that in the Middle Ages and before that, there were no urban parks in cities all over the world, until the middle of the 19th century in Europe, at the beginning of capitalist society, some gardens that used to belong to the royal aristocracy were gradually opened to the public, and the first parks were formed, such as Hyde Park in London, England.

Therefore, the park not only represents the role of the urban ecosystem and urban landscape, but also represents the rights and interests of the people to have the opportunity to share resources equally, and at the same time creates a precedent for the state to provide public services for the people.

It is not an exaggeration to say that this move is a symbol of freedom, equality, and fraternity.

Throughout China's more than 2,000 years of feudal dynasties, the most unconvincing thing is actually the idea of "taking from the people and using it for the people".

Whether it is the Qin and Han dynasties, or the Tang and Song dynasties, or the later Ming and Qing dynasties, they all took from the people and used them for themselves, repairing the palace and the palace, but none of the emperors ever thought of public construction for the people.

Zhumen's wine and meat stink, there are frozen bones on the road, and the misery of the people cannot be smelled, let alone seek for the happiness of the people.

Now, the reason why Li Yang proposed to build a park in Qin is to plant the seed of "equality" and "sharing", which symbolizes "equality" and "sharing", which is "to give the people equal opportunities and share the rights and interests of national resources and welfare", for 2,000 years.

Although the current Fusu loves to build parks, its purpose is to change the old appearance of Xianyang City, in order to give his father a stunning effect, as a gesture of merit, not to give the people the opportunity to share the rights and interests of the country's public resources. However, the completion of the park will not change the original role of the park because of the face project of Fusu, that is, to provide the public with play and leisure services.

In other words, as long as the park is completed, no matter what Fusu's current purpose is, but this park, it will definitely have a far-reaching impact on Daqin in the future.

Perhaps, in the near future, for the sake of the city's landscape, the major cities of Daqin will build parks one after another.

Perhaps, in the near future, in addition to the survival and clothing of the people, for the sake of the happiness of the people, it will also be included in the scope of governance.

Li Yang can't do it in one step, what he can do is to plant some seeds for this nation, let this seed sprout on its own, and then influence everyone's thinking and change everyone's consciousness.

After all, some things can only be done step by step and cannot be achieved in one step.

The hot air balloon floated over Xianyang City, with the east wind, towards the west of the city.

The three people in the hanging basket looked at Xianyang City under their eyes, and their eyes were full of expectations for the future.

What Fusu is looking forward to is the completion of the park and the new transformation of Xianyang City. What Li Yang is looking forward to is a prosperous, powerful Great Qin Empire, where the people enjoy a certain degree of happiness and equal rights.

…………

This manned flight is also the world's first manned air flight, and it is also of great significance.

The hot air balloon flew for half an hour at an altitude of 100 meters in Xianyang City, flew over the entire Xianyang City from the east of the city and landed on the outskirts of the west of the city.

This flight advanced the history of manned hot air balloon flights by more than 2,000 years.

It can be said that Daqin's manned flight, although it is not an airship in the real sense, but a hot air balloon, but in the history of mankind, it is undoubtedly a precedent for manned flight, and it is also the origin of the human space dream and laid the foundation for space flight.

The invention of hot air balloons and the success of manned test flights are destined to be recorded in the annals of human history, which is a matter of pride for the Great Qin Empire.

This matter was naturally published and distributed throughout the country by the Daqin Gazette again, and for a while, the whole country knew about it and was amazed!

Of course, although the hot air balloon was successfully manned and landed safely, Li Yang was still not satisfied with this kind of aircraft.

Because what he wants to build is an airship that can be used in a large number of flying in the true sense.

And this kind of heater that relies on firewood to generate heat and lift into the air not only has a huge safety risk, but also rises into the air, but also cannot determine its flight direction, and completely flies with the wind.

Therefore, on the basis of hot air balloons, to invent a power airship has become the next task.

It's just that to invent a power airship is not realistic at the moment.

Because the power airship is powered by hydrogen or nitrogen to achieve lift, and the additional deflation valve on the airbag is a device to control the altitude and tail sailing direction.

Li Yang knows how to get hydrogen and nitrogen, so the gas is not the difficulty, but the difficulty is actually the air bag that can seal the hydrogen or nitrogen.

Obviously, it is impossible to make an airbag from paper-pasted cloth, because it must be breathable.

Li Yang pondered for a long time, in order to meet such conditions, only animal leather is suitable for making airbags.

It is precisely because of this that Li Yang feels more and more that the application of natural latex, and even the comprehensive development and application of rubber, have extremely urgent needs in the daily life of the society and the development of various fields of society.

As long as rubber can be fully developed and applied, there will be earth-shaking changes in all fields of Daqin.

For example, the wooden wheels and bronze wheels of the carriage can be replaced with rubber tires, and at the same time, the anti-shock device is developed, so the comfort of the carriage is dozens of times improved.

Of course, the application of rubber is not only for tires. Rubber soles, raincoats, raincloths, various hoses...... It can be said that rubber, as a raw material for the rubber industry, is used for unlimited purposes as long as it is developed in depth.

Happily, the origin of rubber, there is already a place in the Americas that is Daqin's overseas base. Next, as long as the sea ship is built as soon as possible, the latex from the Americas will be continuously transported back to Daqin, and at the same time, rubber trees can also be transplanted and widely planted in Daqin.

Thinking of this, Li Yang knew in his heart that the construction of sea ships seemed to be on the agenda.
