Time passed slowly under such circumstances. It takes time for new robots to grow, and it takes time to verify whether the evolutionary trap is effective, and the work of the Science Affairs Committee is still busy, especially Xiao Yun, the person in charge, needs to participate in and plan even more.

In addition to Pluto, Xiao Yun also applied to open a second robot experimental base. Because the Pluto base will be used exclusively for evolutionary trap experiments in the future, and conducting both evolutionary trap and smallpox virus experiments on robots of the same group at the same time may cause inaccurate data, Xiao Yun needs a second robotic experimental base dedicated to smallpox virus matters.

The new robot experiment base was finally selected on the planet Eris. Eris is a slightly smaller and more distant star than Pluto, and it and Pluto belong to the vast and inhospitable Kuiper Belt, which is sparsely populated and rarely passed by cargo or commercial or tourist spacecraft, making it an excellent place for robotics experiments, and designating it as a military exclusion zone will not have any impact on humans in the solar system.

Like the Pluto base, the first dozens of robots were placed on Eare, and they began to grow and reproduce. Dink's team is developing a new smallpox virus that is more lethal and infectious, and when the new virus is properly developed and the robots at the Eristar base grow and multiply to a certain point, a new round of virus testing will officially begin.

The focus of the Science Committee is divided into these two points, and millions of scientists throughout human civilization are busy working day and night to perfect the plan for destroying robots. And at the same time. The rest of the institutions that were formed to combat the robot crisis have not been idle.

Thirty years after Xiao Yun returned to the solar system, he attended the highest-level meeting. Under the coordination of the Retreat Committee, the first star system to be relocated, the people who originally lived in the four galaxies of Tianyuan finally returned to the solar system after a long journey.

The Tianyuan Four Galaxy is a habitable galaxy with a considerable size, and the number of long-term human beings living there is as high as 100 billion. It has long been developed and perfected into an important node in the interstellar map of human civilization, whether it is commerce, tourism, science and technology, or culture. But until the threat of war, all this is useless.

In this way, more than 100 billion human beings have traveled from the four galaxies of the Celestial Yuan to the solar system in various spaceships. These ships are either modified domestic intragalactic ships or tourist ships. The slowest spacecraft can only travel at twice the speed of light, but there is no way, there are too many people who need to retreat, and it is far from enough to rely on the spacecraft collected by the Retreat Affairs Committee, and it is enough to complete this task by launching all the available spaceships in the whole society.

This is a huge fleet of more than a million ships, and even with such a large number of ships, the living conditions within this fleet are extremely harsh. The spacecraft, which was supposed to carry no more than 10,000 passengers, was crammed into more than 100,000 people. Dedicated large base-based manned spacecraft carry more than 10 million people.

People don't even have their own resting room, let alone hibernation equipment. People can only take a short rest on the crowded bunks, and when they are awake, they can only spend this difficult time in the crowded corridors or halls. And such a time...... It lasted for ten years.

Limited hibernation equipment was allocated to the seriously ill and extremely mentally unstable, while the rest of the population was closely monitored by the military, and anyone who tried to challenge the order was quickly and severely punished by the military. Under such circumstances, from the moment the order to retreat was received, plus the time spent on preparations, the entire retreat took nearly 25 years before the more than 100 billion people finally managed to reach the solar system.

During these twenty-five years, the retreating fleet lost thousands of ships for various reasons, and tens of millions of people lost their lives as a result. In fact, excluding the new population and the number of people who died of natural causes, the number of people who died due to various accidents, such as disease, such as suicide, such as conflict, such as spaceship accidents, etc., is as high as 37.5 million.

Most of the population came to the solar system after this long voyage like hell, and the population of 37.5 million people ...... It will remain forever in the vast void of space, and will never have a home.

And this ...... It's just a retreat from one of the closest star systems to the solar system. In the entire interstellar map of human civilization, the number of star systems that need to be retreated is as high as dozens, and among them, any one star system is farther away than Tianyuan IV.

Although the losses were heavy, but ...... Whoever knows it is clear that this is the least costly option. In the face of the threat of the robot empire, it is imperative to retreat.

At the same time, during this total of 30 years, the Retreat Affairs Committee and the Fugitive Affairs Committee were united, coupled with the scientific research and development forces of the Academy of Sciences, led by these three important departments, and the engineering forces of human civilization were fully mobilized, and more than 1,000 "space islands" were built in the solar system.

The habitable planets in the solar system can only support the original population of the solar system, which the more than 100 billion people who have retreated from the four galaxies of Tianyuan cannot carry it in any way. In this case, it is inevitable to build space islands that can carry a large number of people.

These space islands are ten times larger than Earth-class warships, and the maximum carrying capacity of one space island is as high as 150 million people. Of course, in this case, comfort cannot be guaranteed. However, now that the clouds of war are shrouded, it is not easy to survive, and who will go for comfort?

These space islands are all placed between the orbits of Mars and Jupiter, and they will orbit the Sun in a two-year cycle. And if one day, the war situation is irreversible and the robot empire invades the solar system, these space islands can also break free from the solar gravitational pull and escape from the solar system under the impetus of their own power. They can also travel faster than light at twice the speed of light, and as long as they can function, they can carry people into the middle of space.

After the residents from Tianyuan 4 were placed on the space island, under the organization of the civil and industrial departments, the people who had just taken a breath immediately followed the aborigines of the solar system into the busy construction of the project. In the next few decades, more than a dozen star systems will be relocated to the solar system, and although those star systems are not as prosperous as Tianyuan IV, and the population of a single star system is not as large as that of Tianyuan IV, the sum of a dozen star systems will be different - their population will far exceed the population of Tianyuan IV.

It is not enough to have more than a thousand space islands, and human civilization needs more and larger space islands to support its population.

The solar system has become more lively and busy than ever. All the passages are occupied by ships shuttling back and forth, countless materials and people are circulating in the inner solar system, and under the pressure of the clouds of war, human civilization has exploded with unprecedented vitality.

Outside of the retreat, human civilization has not stopped advancing on other fronts. When the potential of a civilization is forced to come out, the explosion of technology will naturally appear. The achievements of basic science and technology and applied science and technology in these decades have exceeded the sum of the past few hundred years, and even the spacecraft that can travel ten times the speed of light has appeared on the design drawings, as long as some key materials science and dynamics problems are solved, this kind of spacecraft will truly appear in human civilization. Technologies that communicate at 100 times the speed of light are also emerging in laboratories and are expected to be used on a large scale in a few decades or less.

In other areas, great progress has also been made in engineering science, materials science, structural science, computing science, life science, military science and technology, etc.

The explosion of technology is a welcome thing, but no one is relaxed for this reason. Because no matter who you are, as long as there is no qualitative change in technology, then the technology of fifty years ago or the technology of fifty years later will be used to deal with the robot empire...... The ending will all be the same.

What should be stolen by robots will still be stolen by robots, and what should be destroyed by robots will still be destroyed by robots.

All of these breakthrough technologies can be used for escape and retreat at best, and they are useless against the Robot Empire. This is hard to accept, but it's true.

The hope of human civilization has always been maintained on the scientific affairs committee headed by Xiao Yun, and this has never changed.

At this time, Xiao Yun was guarding next to the base of the god star, swimming in the ocean of data. Not far from the base, the planet is already filled with robots, just like Pluto decades ago.

"Conduct an evolutionary trap experiment and let the robots start evolving according to the tech tree we have set." Xiao Yun said.

"Okay." A staff member agreed, and then conveyed Xiao Yun's order. Moments later, an abandoned spaceship with special technology was thrown onto Eris and disappeared into the sea of robots...... (To be continued.) )
