At 7 p.m. on August 23, 2084, the Rally Launcher successfully passed through the R-N black hole to complete the space transition and successfully arrived in the Brady Galaxy, which is 162 light-years away from the solar system.

In just four hours since Robin set off from the planet Wendini, they have crossed a distance of more than 100 light-years, setting foot in a completely unfamiliar land and a strange country, and the psychological transformation during this period makes Robin feel as if he has returned to that time three years ago, and he will face the same horror of walking on thin ice three years ago again.

Untying the safety belt that secured himself to his seat, Robin got up and took a deep breath and began to give orders to the officers and men at all levels in the bridge in the usual pattern. Things like activating the radar system for interstellar exploration and activating the communication system to receive navigation radio waves were also implemented under Robin's methodical arrangement.

"Have Martha do the crew medical check, Cecilia, find an open place to dock first and get out of the way."

In today's cosmic era, although people have long been accustomed to interstellar travel, traveling through the four-dimensional space may still have a certain impact on human beings in three-dimensional space.

After leaving the earth and stepping into the unknown huge space of the universe, human beings, as life beings on the earth, are undergoing a huge test after the change of the general environment almost every minute and every second. The prominence of various genetic diseases and the evolution of human beings seem to be in a trigger state at any time, and the transition is the most likely trigger event among various space behaviors. Therefore, in order to ensure the safety of the crew, the spaceship will often conduct a physical examination of all crew members after completing the jump, so as to find out in advance whether there are crew members who trigger genetic diseases and treat them in advance.

This may sound strange, but in fact, when human beings accept a new thing, it often takes a long process to fully adapt, and this process of adaptation is actually a kind of genetic evolution.

Just like radiation in the old days, when radioactive material was first discovered, humans who had never been exposed to it had poor immunity to radiation. Under normal circumstances, a dose of 150rad of radioactive radiation is enough to cause harm to ordinary people, and will continue to accumulate damage in the body, often forming physiological symptoms such as carcinogenesis after 20 years. Under the irradiation of 400 rad dose, the direct mortality rate will reach 5%. The direct mortality rate from radiation exposure above 650 rad is 100 per cent.

Since the fifties of the twentieth century, radiation has become an indispensable element of normal human life. Medical X-rays, computers, mobile phones and other radiation sources appear all the time in the normal life of human beings, which makes the radiation dose of human beings themselves continue to increase in this process.

Until now, in this cosmic age, radiation has long ceased to be a high-risk energy. The 650 rad dose of radioactive exposure, which used to have a direct mortality rate of 100 percent, is now an absolutely safe dose. Under normal circumstances, the radiation dose of humans in the new era is usually more than 4,000 rad, and special cases like Robin can even directly withstand a direct radiation dose of about 60,000 rad. This number is one hundred and fifty times that of humans in the old era, and it is almost close to the radiation resistance figure of cockroaches.

It took nearly 200 years for humans to complete near-immunity to radioactive energy. However, it is not yet completely immune to the negative energy of the four-dimensional space, which is a new high-risk energy.

After all, it has only been 60 years since 2023, when the black hole first came into contact with the negative energy of the four-dimensional space. In the past 60 years, although the rapidly evolving human beings have completed a fundamental transformation in their adaptability to the universe, the non-combat attrition caused by the jump is still inevitable. Therefore, only by conducting a physical examination as soon as the transition is completed and discovering the symptoms of genetic mutation in advance, can the disease be controlled and completely cured in advance.

Half an hour later, Martha quickly completed the physical examination of the ship's 1,700 crew members. In the end, the results were very optimistic, except for four logistics staff who had normal signs of dizziness and nausea, everyone else, including Robin, was in good health and had no symptoms triggered by genetic diseases.

Since then, the radar system has finally completed the interstellar scanning of the Brady system, and obtained the star navigation chart data of the entire Brady system. This made the navigator Borg, who had been anxiously waiting, finally have something to do, and began to busily mark the positions between the planets, stars and planetary moons, calculate the gravitational range of each celestial body and the radiation range of the stellar energy wind according to the scanned planets, star density, and mass, and based on these numbers, calculate the best route to reach each planet.

In addition, Christine, the communications officer in charge of the communication system, also began to make progress, capturing the public communication channel of the Brady system, and finding navigation information and some planetary information in it, providing reference information for Robin to determine the next target to reach.

It took only half an hour to get a first-hand account of this strange galaxy, which is undoubtedly extremely rare. Normally, when a human expedition team develops an unknown galaxy, it often takes days to grasp some limited information, but in contrast, Robin's team is so efficient because of the team's well-trained and tacit cooperation, and on the other hand, the powerful computing power of the central computer extension has greatly helped.

The bridge command post of the 'Assemble'.

After getting first-hand information about the Brady system, Robin immediately called a group meeting of the commanders of the various departments. Among them, the brothers Sierra and Tabbar were not originally qualified to participate in such a meeting, but Robin specially ordered them to attend this meeting due to their mercenary background and combat missions in multiple galaxies.

In the military establishment of the Federation, the status of mercenaries is rather awkward, so mercenaries are never qualified to participate in such caucuses. After defecting to Robin empty-handed, the Saila and Tabbar brothers were already mentally prepared to be ostracized, but they never expected Robin to promote them on this important occasion a few hours later, giving them a chance to officially join the core team. Therefore, when they were ordered to come to the bridge command platform, they immediately obediently restrained the perverse style peculiar to mercenaries, began to salute their commanders like regular troops, and fully abided by the strict military discipline of the republican ** team.

"The first-hand information about the Brady system is here, so you can take a look at it first."

Sitting on the main seat of the podium, Robin habitually swept his gaze over everyone's faces, casually posting the latest information he had just obtained to everyone's personal computers.

There are more than 200 billion stars in the Milky Way, of which nearly 60 billion stars are on the Orion Arm alone, where the solar system is located. And on the basis that each star is a star system, there are about 60 billion star systems like the solar system on the Orion arm of the Milky Way.

Of course, this figure is not accurate. Because there are a few stars that do not operate with a single star, there are binary star systems in addition to single star systems such as the solar system, and triple galaxies such as Proxima Centauri and Alpha binary. Coupled with the continuous annihilation and birth of stars, it is not difficult to accurately count the number of galaxies in the Milky Way.

However, in order to make it easier for interstellar explorers to find the most suitable galaxy for exploration, there are still some criteria that can be used as a reference.

Among them, the size of a galaxy is more or less related to the star that is the core of the galaxy. Compared to a single star system, a double star system undoubtedly covers a much larger area, while ... [This chapter is not finished, please click on the next page to continue reading!] ］
