When Su Han rushed back to Longyuan Star, the entire Longyuan Star was cheering.

This time, they Long Yuanxing not only survived the crisis, but also gained a huge harvest.

Not to mention the war fortress, the batch of materials transported back from the Siqin Empire alone was enough to raise Long Yuanxing's technological level to a higher level.

The most important thing is that Longyuan Star has also harvested five interstellar colonies this time.

With the supply of these five interstellar colonies, Long Yuan Star will not have to worry about the problem of materials.

Here, let's talk about the characteristics of interstellar colonies.

If one civilization becomes an interstellar colony of another.

Then all the resources of the civilization will be mined.

Let's use a simple analogy.

If Longyuan Star becomes an interstellar colony of the Siqin Empire, then all the resources on Longyuan Star will be exploited.

When the planet's resources are mined, interstellar exploration begins.

Once a valuable planet is discovered, then the Siqin Empire will specialize all the creatures on Longyuan Star to that planet and continue to work.

Until all living beings on Longyuan Star are dead.

That is, once they become interstellar colonies of other civilizations, then only extinction awaits them.

One might ask why the interstellar colonies don't rebel.

After becoming an interstellar colony of another civilization, all weapons are surrendered.

How to resist when you are unarmed.

It was precisely for this reason that all Su Han would rather the destruction of Longyuan Star than the interstellar colony of other civilizations.

As soon as Su Han returned to Longyuan Star, he immediately received an interview from the No. 1 boss.

In the Longhua Palace!

The No. 1 boss did not hesitate to praise Su Han, and even intended to hand over the Dragon Kingdom to Su Han for management.

But he was rejected by Su Han.

In Su Han's words, it is very likely that he will go back and forth on several planets for a long time in the future.

Long Yuan Xing still needs to be the person who presides over the overall situation.

The first boss thinks about it, too, and all of them don't insist.

However, at this time, Su Han's prestige in the hearts of the people of the Dragon Kingdom is no weaker than that of the No. 1 boss, it is nothing more than a form and a change of name.

After discussing in the Longhua Hall and determining the future research direction of the Dragon Kingdom.

Su Han immediately rushed to the experimental base.

At this time, the experimental base has been expanded several times and divided into several areas.

When all the scientific researchers in the test base saw Su Han, they all greeted him one after another.

Su Han also responded to this one by one.

Half an hour later, Su Han came to the center of the experimental base.

All the projects that can enter the experiment here are the most needed projects in the Dragon Kingdom at the moment.

Among them, there are some projects that Dragon Kingdom did not dare to think of before.

Zhao Rongsheng, who was busy, heard a report that Su Han came here, immediately dropped the work in his hand and rushed towards the area where Su Han was.

I don't know if it's because of Su Han, or because Zhao Rongsheng has outstanding work ability.

At this time, he had already become the 'head of the experimental base', specializing in various research projects in the Dragon Kingdom.

Seeing Su Han, Zhao Rongsheng came directly to hug him, and said with a pleased smile: "Su Han, you really didn't disappoint me!" ”

Because Zhao Rongsheng was not a combatant, he did not participate in the military operation against Long Yuanxing.

However, Zhao Rongsheng has always remembered Su Han.

Now seeing him appear in front of him safe and sound, he is also secretly relieved.

Unconsciously, Su Han has become the 'backbone' of the Dragon Kingdom.

Zhao Rongsheng couldn't imagine what kind of scene it would be like if the Dragon Kingdom was without Su Han?

Seeing Zhao Rongsheng, Su Han's face also showed a smile.

Since the outbreak of the catastrophe, Zhao Rongsheng's influence on Su Han has been extraordinary.

To sum it up in one sentence, it is 'also a teacher and a friend'.

It can be said that without Zhao Rongsheng's support, Su Han would not have come to this point.

After the two exchanged pleasantries for a while, Zhao Rongsheng's face gradually became serious: "Su Han, I heard that you brought back a lot of very rare materials from the Siqin Empire this time, but you came here for these materials?" ”

"Sure enough, it's still my own teacher who understands me."

Su Han sighed silently in his heart, nodded and replied, "Teacher, you guessed right, this time I came for these rare materials." ”

At this moment, Zhao Rongsheng didn't open his mouth to ask, because he knew very well that since Su Han had found here, he must have his own thoughts.

Su Han sorted out his thoughts for a moment and said with a smile: "Teacher, since we have brought back so many materials from the Siqin Empire this time, I want to try the technology of space folding." ”

Space folding, a technique similar to the space ring in fantasy novels.

However, in the case of space rings, space folding can be achieved through science.

Space folding is a phenomenon in which space is distorted by a strong gravitational pull.

This phenomenon is real, so it is theoretically possible to bend space as long as a certain gravitational force can be reached.

It's like going from one end of a flat piece of paper to the other, in addition to walking in a straight line between two points, you can also fold the paper directly so that the two points are close together.

Therefore, it is generally believed that black holes can travel through distant space, because black holes have an incomparably huge gravitational pull, and even light is inevitably attracted by its huge gravitational attraction, so space is also very likely to be folded under such gravity.

This makes it possible to travel through space in a short period of time without exceeding the speed of light.

Planets are separated by a few light-to-hundreds of thousands of light-years.

Therefore, even if a spaceship travels at the speed of light, it will take several years to more than ten years.

Even if the dragon kingdom now has an antimatter engine, it will take weeks to explore the universe.

If two planets were separated by millions of light-years, it would take years.

Gravity alone controls flight, of course, too slow...... However, if the space is warped repeatedly, it can reach its destination faster.

Now, Longyuan Star already has five interstellar colonies.

These five interstellar colonies are far and close to Longyuan Star.

With the flying machines that Long Yuan Star is now in control, once something happens to these five interstellar colonies, it will take at least a week for the Dragon Kingdom to arrive.

Arriving in a week, I'm afraid the daylilies are cold.

Therefore, Su Han thought of studying space folding technology.

Once the Dragon Kingdom controls this technology, it will be of great benefit to the Dragon Kingdom.

After Zhao Rongsheng heard Su Han's thoughts, his brows subconsciously furrowed: "Su Han, although I know that you developed the space folding technology out of good intentions, but is it a little too hasty. ”

"After all, according to the current scientific and technological strength of our Dragon Kingdom, it is still a little difficult to carry out the experiment of space folding."
