The real farewell, there is no Changting Ancient Road, there is no persuasion to get closer to a glass of wine, that is, in the same morning as usual, some people stay yesterday.

In the silent universe, a spaceship sails slowly, and everything seems to be a still picture.

Life survives in the universe in an infinite loop. Theists call this reincarnation, and atheists call it the immortality of matter.

The six hundred people inside the spaceship are all of the current new civilization. Compared with the eternal changes of the outside world, human beings are constantly changing, and time makes everyone who wakes up from hibernation feel the cruelty from time.

But this series of changes is just a series of small beads of light in time and space, from the beginning to the end, in the eternal universe, it is just a moment......

Accept it or not, you have to accept it!

A week later......

Zhang Yuan has come to his place of work.

People always have to face reality, and it is not his style to be immersed in grief for a long time.

"Mr. Zhang, you are really a strong person, and you are not at the level of sixteen. Many people will be depressed for a month......" Fang Yuhao, his successor, said very understandingly.

“…… What has been lost cannot be returned, and it is more important to focus on the present. What's more, everything in my future is on the ship. Zhang Yuan forced a smile, "Keep yourself busy, and you won't have so many distractions, won't you?" ”

Fang Yuhao recalled the original days and said with a wry smile, "Hey, that's true, I also kept studying to numb myself...... Soon, two years passed. Two years is enough time to smooth out the painful memories of the past. ”

"This kind of simple work seems like a waste of your talent...... I'm sure you'll be able to get started soon. For the next half month, I will hand over all the work projects to you. Then I'm ready to hibernate ......" Fang Yuhao said this, stretching out his right hand.

"No problem!"

The two shook hands vigorously.

The second hibernation will theoretically not be affected so violently, because all the things that should be given up have basically been cut off this time. Therefore, this Mr. Fang Yuhao is also preparing for hibernation with peace of mind and boldness.

Zhang Yuan's next work is mainly about the control of molten salt reactors, which are a breeder reactor based on fission energy, which is currently the main power supply energy source in the spacecraft. In the case of the vast majority of functions turned off, there is no need for the fusion engine to provide energy, so a little power generation is sufficient

Molten salt reactors are simpler than complex fusion engines. Zhang Yuan has learned related structures, such as Brayton thermal cycle, power generation principles, etc., as well as some simple manual maintenance.

His task is also very simple, if the artificial intelligence that controls the molten salt pile raises a serious security alarm, he will be responsible for deciding whether to shut down the lava pile, whether to wake a large number of workers from hibernation, and so on.

"Yes, it's that easy, if it's a small failure, you are responsible for solving it; If something big happens, wake up the big army, and don't force yourself. Six hundred of us can't do too much troublesome maintenance work. ”

Fang Yuhao explained seriously, "Actually, you don't have to worry too much. This thing is not an ordinary nuclear reactor, the outlet temperature is about 700 degrees Celsius, and it does not need to be cooled by water, so it has a very good intrinsic safety. Under normal conditions, you don't have to think about it exploding. ”

Zhang Yuan thought about it, and with a responsible attitude, he asked again: "What about the replacement of parts?" I'm just worried that the nuclear power plant will automatically stop working because of the loss of parts, and it will be very troublesome at that time, and it will be difficult for us to get everything done after the power goes out......"

Fang Yuhao said: "Your worries are indeed very small...... However, three years ago was a big year, the nuclear engine had just been maintained, and the probability of a major failure was theoretically small. ”

"If the molten salt reactor does break down, you can turn on another backup nuclear power unit. You have that authority and you are responsible for it. ”

"Understood, what if the third nuclear power unit also breaks?" Zhang Yuan asked again.

"Then start the fourth ...... There are a total of six molten salt reactor nuclear power units in our spaceship, and when we turn on the fourth one, we will have to think about waking up the large army. ”

Zhang Yuan secretly said in his heart that he should not be so weak, and he should break down so many nuclear power plants in two years.

These nuclear power plants are designed to be robust and durable. Breaking one is already a small probability event, let alone two or three.

"The ship is still new...... Anyway, it's a very quiet and simple job. Don't worry too much. Fang Yuhao saw his thoughts, and said: "When you are bored, you can see what is happening on the earth, or learn some new theories, and time will pass." ”

"By the way, I recommend you a couple of comedies that have just come out, and the pop culture of the 25th century is not quite the same as ours, and some of the things are quite interesting. The film will be shown tomorrow at 8 p.m. at the Grand Opera House in Zone Z. ”

"It's good to be like this movie "Journey to the West", as well as this anime "Dragon Ball", "Migrant Workers Three", ......"

Similar group activities are often held within the community, generally just watching movies and comedy. Activities such as theatrical performances are always unsuccessful, because everyone's mood is generally bad, who wants to sing and dance on stage?

Zhang Yuan hurriedly waved his hand: "Forget about comedies, it's been so many years, and it's really unimaginative to still shoot Journey to the West there...... I'd better learn a little bit of normal knowledge. Learning brings me joy. ”

……

In this way, under the guidance of Fang Yuhao, Zhang Yuan has learned to look at various data for more than half a month, and clearly knows what is a big problem and what is a small problem, which is enough.

Coupled with the fact that he had already learned this knowledge, it was very easy to deal with......

After the smooth handover, Fang Yuhao successfully entered hibernation, and Zhang Yuanlai took over this position.

There are six people in this office, working in three shifts, two in pairs, sometimes one in one group. Everyone is responsible for the same job, which is theoretically enough insurance.

Everyone has their own pastime, some people like to read comics, and some people like to watch movies. The new things that have been produced for more than 180 years are enough for everyone's pastime, especially about the society of the earth's civilization and the development of science and technology, which has always been a very hot topic.
