The shadow of war and the threat of hunger led to a large-scale recession of the Blue Star economy, and the total GDP of the entire Blue Star in 2160 fell by more than 10% compared with 2150. Therefore, the 50s of the 22nd century are also called the "lost decade".

The four superpowers also knew that if the confrontation continued, it was likely that a war would break out to destroy the entire Blue Star, but the ten years of confrontation had made all parties want to stop.

However, the turnaround soon appeared, and in 2159, the famous Chinese physicist Li Chang invented a new type of high-energy battery, which stores dozens of times more electrical energy than lithium batteries. A year later, another physicist in China, Huang Guolong, made a major breakthrough in the miniaturization of nuclear fusion technology.

With the acquiescence of the Chinese government, two physicists, Huang Guolong and Li Chang, disclosed the two new technologies to Lanxing.

New technologies have completely changed the way human society uses energy, alleviating the competition for fossil energy such as oil. At the same time, the emergence of new energy has also provided significant help to Bluestar's agricultural production methods. Humans are able to use light such as ultraviolet spotlights to help crops photosynthesize in high-rise buildings in cities, and sufficient energy can increase the growth rate of plants by two to three times, and the food crisis in Blue Star has been solved.

At the initiative of two physicists, Huang Guolong and Li Chang, hundreds of famous scientists from Bluestar launched a peace initiative, asking Bluestar countries to abandon the arms race, end the armed confrontation, and restore peace to Bluestar.

The Blue Star parties, led by the four major forces, finally responded to this initiative, and after several years of arduous negotiations, the "Yenching Declaration" was signed in Yanjing, China, on October 10, 2164.

In addition to announcing the restoration of peace in the Blue Star, the most important content of the "Yenching Declaration" is the establishment of the Blue Star Alliance. Since then, the Blue Star Alliance has replaced the United Nations as the largest international organization of the Blue Star.

The most important body of the Blue Star Alliance is the Blue Star Council, which is a member of the Council, which has four members and ten vice-members. The four members of the Council are non-re-electable for life, and have one veto power, with one veto each held by the United States, China, and Mao Xiong, and one veto by France and Germany (the veto is only valid if France and Germany are in agreement). The 10 vice-members are elected every six years, and one-half is re-elected every three years. The location of the Blue Star Alliance is located in Huaxia Yanjing, which is also a condition for Huaxia to agree to announce the two new technologies.

The promulgation of the "Yenching Declaration" marked that Bluestar had lifted the threat of war and entered a period of rapid development. Li Chang and Huang Guolong, two physicists, won the 2165 Nobel Prize in Physics and the Nobel Peace Prize together, becoming the only two people in history to win two Nobel Prizes in the same session.

If there is no cataclysm, the blue star that has lifted the energy bottleneck is likely to be a huge development, and the sea of stars may no longer be a dream.

Unfortunately, the sudden solar storm interrupted the ascent of the Blue Star, and the human society that was caught off guard was completely defenseless in the face of the cataclysm, and the Blue Star government collapsed after less than a month. What followed was the complete collapse of the human social order.

This information was all known to Ye Hao from the data stored by Andy. Since Andy was "born", he has been collecting all kinds of information about Blue Star, he is the existence of God in the online world, he is like going in and out of his own backyard, entering various websites of Blue Star, reading and storing all kinds of information. If it weren't for the limited capacity of his storage device, he would probably have stored all the data he could find. Even if he selectively picks some important information to store, the data he stores is terrifying. Andy divides all kinds of data into five levels: general, important, confidential, top secret, and 3S.

The invisible paint provided by Ye Hao to Huaxia is only an important data in the Andy database, on top of the general data. Not even classified data, let alone top-secret data above the classified level.

After all, this invisible paint is only a product of the 30s of the 21st century, and after the military confrontation of the four major forces in the 40s and the great development in the 50s and 60s, Bluestar has made great progress in science and technology. Ye Hao found a space carrier for interstellar navigation in Andy's database, and its level is 3S-class. Of course, as of 2167, the space carrier was still in the design stage, and it could not be built with the technology of the Blue Star at that time.

Ye Hao estimated that with Huaxia's current technical capabilities, as long as the information is complete, the technologies below the confidential level in Andy's database can be thoroughly understood within 3 to 5 years; the confidential level technology will take 10 to 20 years; the top secret level is not to mention Huaxia, and the entire Blue Star cannot solve it in a short period of time, and some technologies are not even conceived.

Therefore, after screening, Ye Hao decided to select some technologies that Huaxia can currently understand in a short period of time and urgently need, and provide them to Huaxia in the near future. Invisible paint was his first gift to the Chinese government.

Ye Hao is ready to return to China for development, after all, he can find a sense of belonging in his own country, with the existence of the bug of the system, and his entire apocalypse as the backing, Ye Hao has a reason to replan his life, and at the same time make some contributions to his own nation.

However, the system and the end times are Ye Hao's biggest hole cards, and it is impossible for him to tell anyone. Therefore, Ye Hao must think of a safe way to cooperate with the Huaxia government.

Ye Hao doesn't want to return to the end of the world for the time being, although the end of the world is not bound by rules and can act recklessly, but facing the threat of death at any time is not something that a normal person can endure after all.

His goal is to set a career plan and find a starting point. In Ye Hao's planning, his career is very ambitious, and some aspects must be supported by the government, which is also one of the reasons why he gave Huaxia technology, why not be happy to be able to win with the Huaxia government?

However, at present, Ye Hao's priority is to get a master's degree. Although with the resources he has now, whether or not he has this degree has little impact on him, but as a person who has a good start and finish, this degree is a summary of his several years of study career. What's more, for him, the current graduation thesis is not the slightest difficulty, just a smooth one.

Ye Hao's graduation thesis is about the manufacture of a new type of material for computer storage equipment, the current civilian computer hard disk size is generally in a few hundred GB to 1TB (1TB = 1000GB), this new material made of computer hard disk in the same size can make the stored data reach PB (1PB = 1000TB) level, which is also the product of the 21st century of the 30s of the 21st century.

In his graduation thesis, Ye Hao made a detailed elaboration on this new material and published some experimental data. These data are only an experimental basis for the new material to be used to make computer storage devices. Ye Hao did not announce the details of the follow-up from the laboratory to large-scale production. This new type of storage device is the starting point of his career, and Ye Hao plans to return to Huaxia for reproduction.

Ye Hao returned to MIT at the end of May and handed over his thesis to his supervisor Keynes, who was very pleasantly surprised after reading it.

The development of computer hardware to this day is actually in a bottleneck period, and the development of hardware materials has not caught up with the development schedule of software. Hardware such as CPUs, memory, and storage devices can no longer be replaced as rapidly as computers did when they first emerged, and the demand for new hardware devices is imminent.

New materials are crucial to the development of the manufacturing industry, and Ye Hao's "discovery" has increased the stored data by orders of magnitude. Although storage devices are not as important as hardware such as chips, as an important part of computers, the improvement of storage device performance has a role that cannot be ignored in improving the overall performance of computers.

After discussing with his supervisor John Maynard Keynes, Ye Hao agreed to publish the paper as soon as possible. At the same time, the supervisor asked Ye Hao to publish the paper in the Massachusetts school magazine, and the supervisor Keynes believed that the paper would cause a sensation, and the publication in the school magazine was also a great opportunity to increase the popularity of the Massachusetts Institute. Although Massachusetts College is already a top university in Bluestar, this kind of opportunity that is bound to attract large-scale attention is not often encountered.

The tutor Keynes was a strict Christian, and he did not ask for his name to be signed in the paper, of course, Ye Hao, as his student, had an obvious increase in his reputation after the publication of the paper.

After obtaining Ye Hao's consent, his supervisor Keynes asked Ye Hao to seize the time to revise and improve the thesis. He himself quickly approached the president of the Massachusetts Institute, and the May issue of the Massachusetts College journal was delayed until June 2.

As one of the top universities in Bluestar, Massachusetts College's school magazine often publishes some important scientific research information, so the school magazine has a wide audience, including elites such as technology, finance, and government.

The fact that the May issue of the Massachusetts College was not released at the end of May as usual quickly caught the attention of some who were curious about the reason for the postponement of the magazine. There are similar precedents before, and they all represent a lot of technological innovation.

It wasn't until June 2 that the four-day postponement of the school magazine came out belatedly.

There are a lot of smart people in this world, and the IT industry is originally a place where elites are concentrated, and since the invention of computers in the 20th century, the IT industry has given birth to countless myths of technology tycoons and wealth. Therefore, all kinds of venture capital and financial giants are always paying attention to every move of the IT industry.

The postponement of the release of the Massachusetts College school magazine immediately attracted the attention of well-intentioned people, which was equivalent to advertising for Ye Hao in disguise.

The paper published on the front page quickly attracted widespread attention. Although the paper only published some simple experimental data and the development prospects of new materials, Ye Hao took a key step: the discovery of new materials.
