In order to protect the lungs of the earth, Zhu Youxiao issued a decree requiring Zhu Cijiong's development of the Americas to only extend to the Panama Canal.

The whole of South America was divided into areas that could never be mined, and the indigenous people who still lived in the area were also driven out of the country, and this area was directly classified as a forbidden area.

Not only South America, but also places such as Antarctica and the Arctic Ocean have been designated as forbidden areas, and human activities other than scientific research activities are prohibited.

Anyway, now that the Ming Dynasty enjoys the resources of the entire empire, there is no need to develop at the cost of destroying the earth's ecology.

In the second year after the construction of the Americas, Zhu Youxiao visited the Americas once, and also had a secret conversation with his eldest son Zhu Cijiong in the Great Lakes Scenic Area for a long time, and since that secret talk, Zhu Cijiong has never participated in the election of the first assistant of the cabinet in his life.

In the blink of an eye, it has been the fifty-first year of the Great Apocalypse, and the Ming Empire at this time has gone through three hundred years, and its territory has expanded to the limit of human activities.

However, the Ming Empire's exploration of new worlds has not stopped, and it is even getting faster and faster.

There are more than 10,000 academicians of the Royal Academy of Sciences, the Royal Academy of Engineering, and the Hanlin Academy, and even thousands of branches have been established in all corners of the world, thousands of national scientific research achievements in natural sciences and social sciences have been awarded, millions of people have been engaged in research on a full-time basis, and there are tens of millions of gardeners working in the field of education.

It is precisely because of the increasing power and speed of the exploitation of knowledge and truth that the economy of the entire empire has developed rapidly, the gross national product has already exceeded five trillion silver dollars, and the annual income of the national treasury is also measured in trillions of silver dollars.

The railway mileage has exceeded 10,000 miles, the road network has almost covered Europe and Asia, several bridges have been built over the Yangtze River and the Yellow River, and the first hydropower station has been successfully built in the Yichang area of the Yangtze River.

This has meant that Daming's electric energy production method has changed from thermal power to water power.

Automotive technology has been improved again, the penetration rate has been further improved, and even various brands have appeared, and sedan cars have begun to be phased out.

Large cruise ships also began to appear, and citizens of the Ming Dynasty could even buy tickets to go directly to the Americas or to Europa.

With the improvement of photographic technology, movies also began to appear on the market, and because of the development of acoustics and optical electromagnetic waves, sound films also came into being.

In the military aspect, smokeless gunpowder has long replaced black powder, body anthracene high explosives have also been successfully manufactured, and various artillery pieces and firearms have emerged in an endless stream.

In addition, with the development of polymer materials, various materials that can withstand high temperatures have begun to be born, which means that in the future, it will not be a problem to manufacture airplanes and even spaceships.

However, Zhu Youxiao has banned the invention and promotion of plastics, as well as nuclear weapons experiments on Earth.

Therefore, many military weapons experts and chemical experts in the Ming Dynasty can only focus on pharmaceutical preparations and chemical textile industries and other civilian equipment, such as washing machines, refrigerators, etc., and begin to facilitate human life as the main research direction, while research to meet the struggle of human interests has begun to become unpopular.

But this does not mean that there is no research, Huaxia has been very interested in understanding outer space since ancient times, and now the Ming Dynasty can only regard aliens as imaginary enemies in military research, after all, there is no opponent on the earth, so it can only increase the research on outer space.

Zhu Youxiao didn't understand why his concubines were so interested in movies with only black and white, so he watched it for a while and then left the palace cinema and walked to the imperial garden.

However, at this time, the eunuch Chen Tingjing hurriedly found Zhu Youxiao: "Your Majesty, the people from Dongchang have come to report, and Li Ge is dying." ”

Zhu Youxiao couldn't help but be stunned for a moment when he heard this, and then ordered someone to immediately send a telegram to the person in charge of the railway, and he wanted to rush to Suzhou immediately.

It turned out that Zhu Youxiao considered that in order to let himself and a group of old ministers who had worked hard for the Ming Dynasty with him better recuperate, he set up two sanatoriums in Suzhou and Hangzhou, Suzhou is dominated by the Humble Administrator's Garden and Canglang Pavilion, while Hangzhou is dominated by the West Lake, and now Li Mingrui is living in the Humble Administrator's Garden.

Zhu Youxiao, who was sitting in the luxurious emperor's box, looked at the prosperity along the way and sighed a lot, and then he couldn't help but feel nostalgic when he thought of Li Mingrui, since he crossed over to be the emperor, more than half of the capable officials around him have gone, such as Wei Zhongxian, Xu Guangqi, Lu Xiangsheng, Yang Sichang and others, and this Li Mingrui is the old minister who has worked with him for the longest time and has contributed the most, and now he is going to die for a long time, Zhu Youxiao can't help but sigh that life is short.

By the time the Humble Administrator's Garden saw Li Mingrui, Li Mingrui was already half dead, and looking at Zhu Youxiao, he could only shout the word "Your Majesty" with his mouth.

Zhu Youxiao saw him looking at him with tears in his eyes, and he choked up quite sourly for a while: "Old Li, I still owe you a first assistant, don't just go like this, I promise you, as long as you can get up now, I will make an exception, and directly use the emperor's order to let you be the first assistant, and let that Xiao Yang stand aside." ”

Li Mingrui shook his head, said two words of "no" and closed his eyes.

And Zhu Youxiao had to sigh when he saw this, and ordered Li Mingrui to be buried thickly.

However, Li Mingrui can be regarded as the end of his life, after all, he also lived for 86 years.

After Zhu Youxiao visited Li Mingrui, he also lived in Suzhou for a long time, and lived here for ten years.

And in this decade, Daming has begun to build the first airplane, and in a short time it has flown over the Pacific Ocean.

Not only that, but significant progress has also begun to be made in the study of outer space, especially computer systems, which have begun to enter the research stage, hundreds of years ahead of their original history.

During this period, the political competition in the empire also remained hot, and Yang Tinglin was resigned in the 55th year of the Apocalypse after serving a second term.

Zhu Youxiao gave Yang Tinglin the title of Earl of Xindu, which can be regarded as a compliment to the development of the Americas during his reign.

Zhang Dai continued to participate in the fourth general election of the first assistant to the cabinet, but in the end it was Gu Meisheng who suddenly won the big victory.

Gu Meisheng is the first female first assistant of the Ming Dynasty, which has caused a lot of public opinion in the society, but because of Zhu Youxiao as a backer, this Gu Meisheng still sits firmly in the position of the first assistant of the cabinet.

Gu Meisheng was also re-elected, but just before the start of the 63rd year of the Apocalypse, the Ming Emperor Zhu Youxiao suddenly issued an edict of abdication, which caused an uproar for a while.

No one thought that the Ming Emperor Zhu Youxiao, who was still in good health, suddenly abdicated, but the emperor's order could not be violated, and people were more concerned about whether His Majesty really wanted to abdicate to the crown prince Zhu Cirong, and who the new Shoufu would be, and when the emperor and Shoufu at the top of the Ming Dynasty ruled were all newcomers, what new look would the empire have.

There is no suspense that Zhu Youxiao did abdicate to Zhu Cirong, and also set up an advisory committee, and Yang Tinglin became the chairman of the Standing Committee, whose members are a group of old ministers, including Shi Kefa, who is over 80 years old.

Unexpectedly, this time the first assistant was not Zhang Dai but Li Dingguo.

Zhu Cirong and the 64th year of the Apocalypse ascended the throne and changed the Yuan, and the empire officially entered the era of Zhu Cirong and Li Dingguo.
