In March 2016, Alpha Go (Alpha Dog) went to a man-machine battle with South Korean Go world champion Lee Sedol, and Alpha Go defeated the human player with a score of 4:1, marking that human society officially entered the era of "weak" artificial intelligence.

In December 2018, the American Voyager 2 planetary probe officially entered interstellar space, starting a scientific journey for mankind to explore other star systems beyond the solar system.

In early 2019, the United States announced its plan to "go to the moon again", and it will complete another moon landing in 2033.

In November 2035, the United States announced the "Mars landing" plan, followed by superpowers such as Russia and China, setting off a global space race boom.

In January 2051, the high-density superchip Super-Core jointly launched by Intel and Huawei of China was released globally, and the density of human computer chips reached nearly the nanometer level, Moore's Law completely failed, and classical computers developed to the extreme.

In the 22nd century, with the rapid development of human science and technology, the era of "weak" artificial intelligence has matured, and human beings have entered the era of "intelligent robots", and intelligent robots have replaced traditional artificial productivity.

In March 2153, the world's first quantum computer came out, marking the beginning of mankind's march into the field of "strong" artificial intelligence, and also triggered a great crisis of "robots replacing humans".

In September of the same year, in the field of astronomy, scientists confirmed the discovery of the planet "Polban" 5 light-years away, which is suspected to have signs of life like Earth.

In September 2193, humanity suffered the greatest catastrophe since the creation of the century, and the Polban planetarians launched an invasion war against the earthlings, and the earth was in danger and humanity was in danger.

In the face of the invasion and slaughter of species in outer space, mankind has shown unprecedented unity, and the people of the world have united and fought bravely, but they still have not been able to stop the attack of the Polban stars.

In the midst of successive defeats, the nuclear-weapon states led by China, the United States, and Russia had to launch a "nuclear war" on the homeland of mankind, and thousands of nuclear bombs carried out nuclear strikes on aliens around the world, and at the same time killed and injured mankind itself in a large area.

After paying an extremely heavy price, humanity finally defeated the Polbans, driving the aliens out of Earth in 2196.

The post-war earth was devastated and chaotic, and the "nuclear winter" caused by nuclear war caused mankind to suffer a lot, and human economy, science and technology, and culture regressed for nearly a hundred years!

A new order was re-established after the war!

In Asia, the Chinese Communist Federation (China) became a major power; the formation of the Republic of Russia in northern Asia and Europe; Formation of the Commonwealth of America in North America; And in Africa, the African Union was formed.

After analyzing the post-war situation, many scientists and military strategists felt that this "invasion of outer space" was more like a tentative invasion by the Polbans, and that a larger-scale colonial war of aggression might be yet to come.

In order to defend the independence and freedom of the earth and the inheritance and continuation of mankind, under the strong advocacy of China and Russia, and on the basis of preserving the existing national system and national borders, a closer, mutually helpful and united global organization has been formed to share global resources and jointly fight against the Polbans.

In 2201, at the beginning of the new century, the Earth Defense Alliance (EDA) was officially established to share the earth's resources and defend the earth's peace.

In the same year, the Earth Defense Coalition (EDC) was also officially formed, aiming to build a powerful army against alien creatures.

What the outside world doesn't know is that in a hidden forest in the Federation of America, China, the United States and Russia have also established a research institute dedicated to aliens - the Alpha Special Biology Research Institute.

After a century of intensive development, the earthlings did not wait for the Polban people to invade again, but pushed the development of science and technology to a new height.

The Alpha Special Biology Research Institute has also transformed into a very mysterious special academy - Alpha Academy, which the Chinese prefer to call "Assault Academy"!

In the summer of 2319, Su Jianqing, who was extremely biased, almost failed the college entrance examination, and his aunt was ready to spend money to let him mix with pheasant university, which could be regarded as an explanation to his underground parents.

Just when Su Jianqing was about to choose which pheasant university to go to, he unexpectedly received a special invitation letter from the Raid Academy, and he didn't care about this "waste paper" at all, because he felt that no matter how tall his name was, it was just a pheasant, not to cheat the money in his pocket!

But Su Jianqing never expected that this assault academy also sent a guide student Tang Bora senior sister to inspect herself, the key is that this guide student is a charming goddess, under the temptation of the senior sister, Su Jianqing became interested in this academy, or interested in this senior sister.

Su Jianqing went home to "Dianniang", and searched for information about the Assault Academy in the Dianniang search, but there was very little useful information that could be found, which made Su Jianqing suspicious of the senior sister's words, but Su Jianqing vaguely remembered that in the confidential information of the EDA headquarters, he had seen this "Assault Academy" a few times.

After Su Jianqing and his aunt introduced the situation of the Raid Academy, his aunt agreed to him to go to the Raid Academy without hesitation, the reason is very simple, after graduating from the Raid Academy, the package will be distributed! Although the tuition fee of tens of thousands of alliance coins is a bit expensive, my aunt can still afford it! By the way, my aunt also wants Su Jianqing to go abroad to have a look!

Su Jianqing also accepted his fate, anyway, they are all pheasant universities, and the pheasants in China are also on it, and the pheasants in foreign countries are also on it, maybe the foreign pheasants have a different flavor!

After traveling across the ocean and thousands of miles, Su Jianqing followed his senior sister to the Federation of America, and entered this "Assault Academy" inexplicably and confusedly.

When Su Jianqing entered this academy, he discovered the perversion here, where is this bastard to get the pheasant university, this is clearly the devil training camp where the super elite gathers!

Where is this suitable for a bastard like himself? Su Jianqing felt that he had fallen for the senior sister!
