The spaceship "Explorer" is quietly moored in the void, and after each warp flight, a comprehensive inspection of the ship is required, which usually takes several days.

Of course, this is for safety and caution, and if you are really in a hurry, you can continue to fly at warp speed.

In the control and command center of the 'Explorer' space battleship, Captain Liao Yuan is sorting out the information collected recently and reporting to the base camp.

Located 88 light-years from the solar system, the Explorer spacecraft has explored dozens of planetary systems and discovered dozens of living planets.

Dozens of civilizations have also been born on these dozens of life planets, from the most primitive tribal civilization to feudal civilization, to level 1 civilization, level 2 civilization, and civilizations at all stages, but so far there has been no interstellar cosmic civilization that has reached level 3.

The vast cosmic void is like an endless ocean, and the home star and the home galaxy are like an island, and these civilizations seem to be trapped on the island, with no way to contact the wider world outside.

"This is a good thing for Xinghan, which means that we will not encounter any resistance when we Xinghan expand in the future, and it also means that the civilization level of our Xinghan is relatively high, and the civilization that can crisscross the starry universe is like the Europeans who have mastered the navigation technology in the Age of Discovery, and their routes are all over the world."

After Liao Yuan reported the situation of the 'Explorer' to the base camp, he also habitually wrote a diary.

He is a high-achieving student who graduated from Xinghan Interstellar Navigation University, which is different from the top universities such as Xinghan University and Xinghe University of Science and Technology, it is a professional university, which offers very few disciplines, the most famous of which is naturally the interstellar navigation major.

This major is specially used to train talents for interstellar navigation, and most of the graduates are active in spaceships and space warships in various fields of Xinghan, and they are all extremely good captains and captains.

Xinghan University and Xinghe University of Science and Technology, the top universities in Xinghan are mainly focused on cultivating scientists, and the students who come out are basically engaged in scientific research-related work, of course, there are also interstellar navigation majors, and they are not bad, but they are not as good as Xinghan Navigation University majors.

The students of Xinghan Interstellar Navigation University are required to do one thing from the beginning of entering the university, that is, to keep a diary, and write it every day, because it is a good habit to refer to the European captains of the Age of Discovery.

By writing a diary, you can record a lot of information and content, and at the same time, in the process of writing a diary, you can also reflect on what you do every day, so as to continuously improve yourself, and also provide a lot of reference for later navigation.

It has been many years since Liao Yuan graduated from Xinghan Interstellar Navigation University, from an ordinary crew member at the beginning, slowly promoted to assistant to the captain, deputy captain, and now to the captain of a huge space warship, he has always adhered to this habit.

"The distance of 88 light years is an extremely long distance, but for the universe, it is only an insignificant distance, the universe is so vast, we humans still have a long, long way to go."

Using a virtual watch, in the virtual diary world, Liao Yuan wrote such a paragraph, which is his heartfelt sigh, the universe is too big, and human beings are too small.

"Captain~"

Just as Liao Yuan sighed at the dark starry sky outside, Cao Yadong walked over.

"Mr. Cao~"

For every member of the 'Explorer', Liao Yuan is very clear, not only can he sit in pairs one by one, but also can know everyone's ability, which is also an ability that he must have as a captain.

Spaceships and space warships sail in the interstellar universe, and there will inevitably be breakdowns, and how to save themselves far from the base camp is very crucial.

Therefore, the captain must have a clear understanding and mastery of everyone on his ship, know what kind of people to use when and when, and know the abilities they have mastered.

Some people are engineers who can repair spaceships, some people are cosmic astronomical scientists, who can carry out interstellar positioning, etc., this information is very important, and professional things are done by professional people.

Cao Yadong is the leader of the team of cosmic astronomical scientists accompanying the battleship, of course he knows, and he can even recite Cao Yadong's information.

Cao Yadong is over 120 years old, graduated from Galaxy University of Science and Technology, is a proper top student, studied cosmic astronomy and physics in college, and obtained a double degree.

After graduation, he followed the master of Xinghan in the field of cosmic astronomy, Long Yuankong, this Long Yuankong is not an ordinary person, he is not only a master in the field of cosmic astronomy, but also a master in the field of space science and physics.

The theoretical breakthrough of the warp engine was the first to be Long Yuankong, and to be able to learn from such a bull fork mentor, Cao Yadong himself is a very powerful genius.

"Captain, should we be on our way back according to the itinerary?"

Cao Yadong asked with a smile.

"Well, we really should have to go back to explore a planetary system further, it's been a few years, and it will take a few years to go back and take another route."

Liao Yuan thought about it and nodded and said.

According to the plan, this time they were exploring the galaxies around the solar system within 100 light-years for about a decade, and now a few years have passed, and according to the itinerary, they are almost going back.

Of course, in order to maximize efficiency, the return journey is different from the distance from the one that came from, so that dozens of more galaxies can be explored.

"Captain, there's a major discovery on my side, and here about 1,000 light-years away, we may have discovered a small black hole."

"The stars around this black hole are too dense, in the past we always thought it was a star, so we didn't pay attention to its specialness, but this time, after our unanimous analysis, we believe that there should be a black hole here, so can we continue to explore, even if it is a few hundred light years further away, we can determine this black hole."

Cao Yadong's mind moved, and sent a message to Liao Yuan through the virtual watch, and then the thoughts of the two appeared in the virtual world, through the virtual world, Cao Yadong also told the latest discovery of his team.

"There could be small black holes?"

As a qualified captain, although his attainments in the field of cosmic astronomical science are not as professional scientists as Cao Yadong, his level is definitely not bad, and he needs to pass relevant professional exams.

The black hole thing, Xinghan's elementary school students can name a lot of things, not to mention his captain, and now he heard that a small black hole could be found in the starry sky only about 1,000 light years away, and he was also in the spirit.

"Can you be sure it's a black hole?"

Liao Yuan carefully studied Cao Yadong's information, thought about it and asked.

"It's not 100% sure yet, but the probability is very high, the stars here are too dense, hundreds or thousands of times denser than the surrounding stars, which is very abnormal."

"If we weren't in where we are, we wouldn't even be sure of that, but when we're on this side of the solar system, the picture we take of this position looks like a star."

"But it's not, it's so dense that it looks like a star from a distance."

Cao Yadong is not sure, but after careful comparison of the data, he can still find the special features of this area.

"What do I need to do?"

Liao Yuan nodded, thought for a while and asked.

"If we continue in this direction for a few hundred light-years, I will be sure that there is a black hole here, and this will require you to ask the captain for instructions from above."

Cao Yadong thought for a while and said.

"At the moment, our Explorer is carrying enough supplies, but the above side may not agree to move forward for a few hundred light years, because our original plan was to only operate within a hundred light years around the solar system."

As soon as Liao Yuan heard this, his mind moved, and he immediately connected to the warehouse information of the 'Explorer', the materials carried on the battleship are very rich, enough to support it, and as for the nuclear fusion fuel used for fuel, it is extremely sufficient, so don't worry about it.

However, as a captain, he also knew that the most important thing he needed to do was to carry out the orders from above, rather than changing the voyage at will, because this would have a great negative impact on his superiors, and at the same time, changing the voyage indiscriminately was very likely to bring unknown risks, which was the last mistake that a qualified captain should not make.

"This is a good opportunity to explore black holes, and if we miss this one, we won't have it, and I think the above will agree, because we are here to explore."

"Now that we have finally explored the place where there may be a black hole, I think the scientific community in the base camp will definitely give us the greatest support for such a major discovery."

Cao Yadong is a scientist, he is so excited now, he can't wait to fly over now and explore carefully.

But Liao Yuan's consideration is different, he is the captain of the ship, not only to complete the tasks assigned by his superiors, but also to consider the safety of the battleship, taking into account the feelings of most of the crew on the ship, etc., and he can't make decisions at will.

"I'll hold a crew meeting and hear everyone's opinions first."

"If everyone has no opinion, I will apply to the base camp, and if the base camp agrees, we can continue to fly in this direction."

After thinking about it, Liao Yuan also replied, in fact, he also wanted to go and see.
