Seeing the students who were so excited that they couldn't wait to brag in front of others, Zhang Yuan quickly changed the topic: "Okay, fellow students, although this secret is not a top secret, it must be kept as much as possible." If it is known to everyone, it is not appropriate. ”

"We have a strategic partnership with the Torth civilization, and if it goes well, in the future, the curvature spaceship from the interstellar trading market will take us away."

"But if those ships don't arrive on time, we'll have to rent a large ship from the Toth civilization, after all, they have six motherships, and we don't need to build one ourselves to save time...... In this way, the two civilizations have to carry out a series of exchange of interests. ”

If a civilization wants to develop for a long time, it must take into account all the big and small things.

The final stage of the entire neutron star collision plan needs to rely on the power of the interstellar trading market, but it cannot completely rely on the trading venue......

In the event that the market breaks the contract, the whole plan has to be executed.

The planetary fortress, which already has fundamental power, is currently moving at a distance of about 1.6 astronomical units from the two neutron stars, and its orbit is approximately an ellipse.

The planetary engine on top was only 20% on, and the engineers put a final safety check on it.

When it came to this topic, all the students were even more excited, they had not been exposed to the so-called interstellar trading market, and some expected and some doubted.

Zhang Yuan looked at the students below and said, "If the spacecraft of the interstellar trading market arrives on time, then these planetary engines will start on time and cut into the three-body movement, and everyone will escape from this star field." This is certainly the best scenario. ”

"As for the worse plan......

"There is no cosmic string in this star field, and if it is propelled by an ion engine, it will take three hundred years to sail, which will undoubtedly affect the best observation time. The probability of us getting curvature technology is a few percentage points lower. ”

Seeing that the class time was almost up, Zhang Yuan changed his words, "Okay, that's all for today's lesson, let's get out of class, sort out what you have learned, and be interested in taking a look at the literature in this area, although the development over the years is not too big, the next promotion work will depend on ourselves." ”

"Class."

"Goodbye, teacher!"

A few students deliberately turned their heads and waved at him.

Zhang Yuan sorted out the documents in his briefcase, and only after seeing that the students had all left the classroom, he breathed a sigh of relief.

When a professor or something...... It's the first time in the world, and sometimes it feels quite stressful.

This course is difficult, and these students are carefully selected for their academic qualifications at least master's level...... However, the high difficulty of comparing the extra perception will still eliminate a large number of people.

At the Deep Space University, he not only taught master's and doctoral degrees, but also was responsible for undergraduate studies, mainly mathematics and the history of new civilizations.

Teachers impart not only knowledge, but also exporters of values.

At present, children's primary and secondary education is completed by robots, and there are generally no major problems. The whole process of categorical education is quite mature, and the robot teacher is able to do this work.

Universities, however, are different.

University is an important part of the school and society, and students will have a higher level of freedom after graduating from high school. How to adapt to this higher freedom is an important issue, for example, in the past earth civilization, many outstanding students were degraded in college, they did well in high school, but they couldn't keep up with college; There are also some students who have risen again in college, that is, subjective initiative has played a big role.

Coupled with the increase in the difficulty of learning, the assignment of social work and other important tasks, university teachers are still taught by humans.

Then, this kind of human teacher, of course, is the better the moral character, the better, and the higher the role model, the better.

Even the requirements for moral character are greater than those for academics.

If the teacher's ass is crooked, the more knowledgeable he is, the more reactionary he becomes, and the group of students he teaches will of course become a social nuisance.

Zhang Yuan doesn't have much of a task now, except for teaching, communicating with the Tuosi people and discussing cooperation projects, he will work hard to learn new knowledge in his spare time, which is also very pleasant.

“…… The real research task has not really begun yet! Hey, I don't know if the spaceship of the trading market will arrive in time. ”

Zhang Yuan stretched his waist, came to the "Big Rice Bucket Canteen", and ordered a "Golden Spicy Chicken Roasted Fragrant Rice Burger".

The big screen in front of you is showing the development of the entire civilization in recent years.

In the past 1,400 years, most of the resources of the new human civilization have been tilted towards the construction of planetary engines, and the resources and population for scientific and technological innovation are not many, but the progress in science has not been without results.

The experience accumulated over a long period of practice has brought about a great qualitative change in the field of human engineering, and many spaceships have been updated, including super-large transport spacecraft, more powerful engines, etc., and these experiences are not useless.

Countless ships can be seen on television coming and going above a Jupiter-like planet, collecting large amounts of nuclear fuel.

The purpose of collecting nuclear fuel is to create various super-high-yield hydrogen bombs.

There are also a variety of military ships with strong maneuverability, which were mass-produced at a time when relations with the Thoth civilization were deteriorating......

Even if the curvature technology is not obtained in this event, the performance of these ships can be called the pinnacle of a third-level civilization!

Of course, the gap between the spaceship of the third-level civilization and the fourth-level civilization is very large.

If the spacecraft of the fourth-level civilization is compared to a "supersonic stealth aircraft", the spacecraft of the third-level civilization is just a propeller aircraft during World War II. A second-level civilization ship is equivalent to a wooden plane that is barely able to fly.

The fourth-level civilization beats the third-level civilization is hanging, and even directly zero loss.

However, the fight between the third-level civilization and the second-level civilization is also a hanging, but it does not necessarily achieve zero loss.

This is also the main reason why some fourth-level civilizations are reluctant to popularize curvature technology in large quantities, and even conclude some treaties in the trading market.

Curvature technology has brought too much improvement in military strength and mobility.

If humanity acquires curvature technology and is promoted to a fourth-level civilization, it may also sign up for this jump.

As for the rest of the industries, although there has been no particularly major qualitative change, they have also developed. Every industry has expanded a little bit of success, and the technology tree has naturally grown a lot of shoots. Just waiting for an opportunity, it can quickly flourish.

"It's not a wasted time, is it...... Development to the present, itself should be slow progress, where can we make great strides? ”

After a cursory glance at the scientific and technological achievements, Zhang Yuan felt quite satisfied.

"Hey, Lao Zhang, let's eat!"

Just thinking like this, there was a capable man's voice in his ears, it was engineer Ye Kaifu, who, like Zhang Yuan, was the first pioneer to leave the earth.

When Zhang Yuan was still the captain of the Kunlun Mountain Fleet, Ye Kaifu was his right-hand man, specializing in mining and other logistics work.

This kind of talent with special mining skills is, of course, forced to come out.

When Zhang Yuan saw this guy, he also showed a happy smile, "It's rare, today is your holiday?" Eat I invite you to eat golden chicken rice! ”

The two chatted casually while eating.

Perhaps because of the influence of the times, the proportion of the 500,000 pioneers who left the earth at the beginning became transcendent is higher than that of the rest of the generations.

Suffering can lead to human growth.

Zhang Yuan felt that the proportion of middle-aged and elderly people in this era, that is, those who did not leave with the previous spaceship, should also be very high.

In other eras, it will be relatively lower.
