The current Long Yuan Star has returned to its former glory, the only difference is.

There are not many countries on the Dragon Yuan Star, and only one regime is left in the Dragon Kingdom.

After all these years of development, the scientific and technological power of the Dragon Kingdom has been raised to a rare height.

On the main road, countless light buildings stand tall, and countless high-tech buildings can be seen everywhere.

Because the total population is not very large, many factories have been covered by artificial intelligence.

Today's human beings only need to manage, not stand on the assembly line, and work day after day.

Under such a premise, the living standard of the Dragon Kingdom has improved a lot.

During this period, Su Han also deliberately created a virtual VR space.

In this space, human beings can say goodbye to their deceased relatives to relieve the pain of lovesickness.

Of course, in order to prevent humans from becoming addicted to this virtual space, Su Han made many restrictions.

Under Su Han's leadership, the Dragon Kingdom gradually became prosperous.

On this day, Su Han, as usual, sat in his office, planning the future of the Dragon Kingdom.

But at this time, the door of the office was pushed open, and Liang Shuang walked in from the outside.

Seeing that it was Liang Shuang who walked in, Su Han secretly frowned.

Of course, this is not because Su Han hates this Liang Shuang.

It's just that recently, Liang Shuang finally found his other half, and often wanted to introduce a girlfriend to himself, which made Su Han feel very distressed.

It should be explained in advance that Su Han is definitely a normal man, and the reason why he is not looking for a girlfriend now is because he has not met the right one.

Su Han is not the protagonist in some novels, the essence worm is in the brain, and he can't walk the road when he sees a beautiful woman.

In his opinion, if the two really want to spend their lives, they must at least have a common hobby.

But Su Han's biggest hobby is to engage in scientific research and plan the future development of Long Yuanxing.

It's hard to find like-minded 'mates' in the Dragon Kingdom.

Liang Shuang found that Su Han looked at him with an unhappy face, and chuckled: "Team Leader Su, don't look at me with such eyes, this time I came with a mission." ”

Task?

Su Han asked a little puzzled, "What task?" ”

Liang Shuang didn't rush to answer Su Han's question, but after pulling a chair and sitting down opposite him, he squinted his eyes and asked, "Team Leader Su, if I'm not mistaken, you should be twenty-six this year!" ”

In the year when the Savage Era occurred, Su Han was only twenty-one years old.

At this time, five years had passed since the Barbarian Era, and Su Han was naturally twenty-six.

Su Han didn't expect Liang Shuang to ask himself this question, the whole person was stunned for a while, nodded and said, "That's right, I'm twenty-six this year, but what does this have to do with the task in your mouth?" ”

Su Han was very curious, what does his age have to do with the task in Liang Shuang's mouth?

Liang Shuang glanced at Su Han, sighed and said, "Team Leader Su, the No. 1 boss has given me a death order, and you must solve your personal problems before you are thirty years old, but now ......"

"Get out!"

Before Liang Shuang could finish speaking, Su Han interrupted angrily: "The No. 1 boss is now in a semi-retired state, how can it be related to my personal affairs?" ”

"How is this impossible!"

Liang Shuang's words suddenly became serious: "Team Leader Su, we are human beings, not gods, after all, there is an old day, but the development of the Dragon Kingdom is inseparable from you." ”

"If you can give birth to a son and a half daughter at this time, it will definitely ......"

"Stop."

Hearing Liang Shuang's words, the more outrageous it became, Su Han hurriedly stopped.

Let's not say that I don't have a partner yet, even if I do, the rest of the children may not have the talent in this area.

How did it get to Liang Shuang's 'dog's mouth', and the taste changed.

Liang Shuang doesn't seem to give up, and is ready to 'persuade'.

But at this time, the office was pushed open again, and a figure walked in in a panic.

Looking at the staff who broke into the office, Liang Shuang was a little dissatisfied.

I'm 'educating' Su Han here, what kind of mess is this guy coming to make.

The staff member didn't expect to bump into Liang Shuang here, was stunned for a moment, walked quickly in front of Su Han, and said with a serious face: "Team Leader Su, just now, our signal receiving station in the Dragon Kingdom received a special signal. ”

What!

When Su Han heard this, he quickly stood up from his chair and asked in a deep voice, "Is it a distress signal from our interstellar colony?" ”

Over the years, the Dragon Kingdom has once again embraced some of the lower civilizations.

Let those low-level civilizations become the titular interstellar colonies of Longyuan Star.

Over the years, the Dragon Kingdom has also received distress signals from many of these interstellar colonies, and has helped to solve problems.

Liang Shuang saw that Su Han had something to deal with, and he also put away the laughter just now, and his expression became serious.

But what the staff member said surprised the two of them.

"Team Leader Su, the signal we received is not a distress signal, but an invitation letter."

Invitations?

When Su Han heard this, the whole person was shocked!

Over the years, although the Dragon Kingdom has developed rapidly, it has not come into contact with other advanced civilizations.

This is good, how could other civilizations send invitations to Long Yuanxing?

In order to find out the truth of the matter, Su Han got up directly and walked towards the ground signal receiving station.

In the ground signal receiving station, several staff members are busy back and forth.

When they saw Su Han, they immediately stopped what they were doing.

One of the staff members wearing special costumes came to Su Han and said respectfully: "Team Leader Su, you are finally here, just half an hour ago, we received a signal from the Alpha Civilization. ”

"Through our translation, we know that the main content of this signal is to invite our Long Yuanxing to participate in the Cosmic Civilization Exchange Conference."

Cosmic Civilization Exchange Conference!

Hearing this, Su Han quickly searched in his mind.

Through Murphy's memory, I learned that in the vast universe, a cosmic civilization exchange conference will be held every thousand years.

The organizers of the Cosmic Civilization Exchange Conference are the four seventh-level civilizations!

In this way, they get the science and technology they want.

Of course, in exchange, the four seventh-level civilizations will also exchange the science and technology they want.

In addition to the four seventh-level civilizations, other civilizations can also exchange the science and technology they want in this way.

However, not all civilizations can participate in the Cosmic Civilization Exchange Conference!

Only Level 3 cosmic civilizations are eligible to participate in the Cosmic Civilization Exchange Conference.

Obviously, after Long Yuanxing was promoted to a third-level cosmic civilization, he had already begun to receive the attention of the four seventh-level cosmic civilizations.

Otherwise, there would not be a special civilization to notify them to participate in this cosmic civilization exchange conference.
