As Guan Ju said, this is indeed an unprecedented big trouble.

Ding Sheng, who had seen a lot of strong winds and waves, still changed his face after hearing the news, so that he was speechless for a long time.

"You're currently the first human to have this information, so if there's anything you need my help with, just ask. Finally, it was Guan Ju who broke the silence.

"I understand..."

Although he said that, it is no exaggeration to say that Ding Sheng's brain is a mess now.

In the house in her hometown, Ding's mother first noticed that something was wrong with her son, "Xiaosheng, are you feeling unwell?

"No... No, I... Grandpa, Mom and Dad, I have some things to deal with, I'm afraid..."Speaking of this, Ding Sheng even choked up a little.

So, I've just come back, and I'm going to leave again?

"Go ahead. Grandpa Ding nodded.

"Good job. Father Ding clenched his fists.

"Go home early. Ding's mother smiled.

Probably found something from his expression, the explanations of the three relatives were extremely simple, and it seemed that he didn't want Ding Sheng to have too much pressure.

Of course, for their sons, the Ding family has always believed and supported them unconditionally.

"Then I'm leaving. ”

Looking at the family in front of him, Ding Sheng really didn't have any reason to hesitate any longer, cheered up his spirits, and strode out of the room.

"Guan Ju, contact Dean Song. ”

"Good!"

It is said that there is no real empathy in the world, but as a super intelligent system that can share brain waves with Ding Sheng, Guan Ju can feel that the familiar Ding Sheng is back.

...

Chinese Academy of Sciences, Office of the President.

Due to the sudden appearance of a super particle accelerator in Bristol, which was many years ahead of its time, it indirectly led to the Huaxia Future Annular Positron Collider project on the verge of bankruptcy.

Because no one wants to invest a lot of manpower, material resources and time, and the accelerator built is still far behind the rest of the people.

Therefore, Academician Song Lizhang, the general director of the plan, was very frustrated.

However, the truth is, this is not the worst case scenario.

So what's the worst-case scenario?

Ding Sheng, the only young talent who has the opportunity to help the rise of China's future particle accelerator and once again catch up with Europe and the United States, is the star of future science, who disappeared in Bristol seven months ago.

Compared with the future particle accelerator plan being blocked or even suspended, the loss of Ding Sheng undoubtedly hurt Song Lizhang even more.

Coupled with his aging age and increasingly serious condition, the recent Song Lizhang is much more irritable than his previous kind and kind character.

In general, there are no special circumstances, and assistants rarely come in to disturb him.

For example, today's...

"Dean, your call. The assistant had a very clear smile on his face.

"You just deal with it. Song Lizhang didn't raise his head.

"Dean, it's Ding Sheng. The assistant tried to keep himself calm.

"What are you talking about?" Song Lizhang raised his head suddenly, his eyes widened, and he hurriedly stretched out his hand and said, "Hurry up, bring it and I'll listen to it!"

"Dean Song, I'm Ding Sheng, I'm back. Hearing the slightly rapid breathing on the other end of the phone, Ding Sheng said heartily.

"I knew you kid wasn't going to be so simple... It's good to be back, it's good to be back. Even the assistant on the side could hear that Song Lizhang's voice was obviously trembling slightly.

This is probably the joy after discovering that the white-haired man sent the black-haired man was a false alarm.

"Dean Song, I brought a not-so-good news, you have to be mentally prepared..."

Half an hour later...

"Ding Sheng, this kind of thing is not a joke, what you said is true?" As the leader of the Chinese Academy of Sciences, Song Lizhang obviously couldn't believe it before there was substantial evidence.

Even if the person who brought this information was Ding Sheng.

"Do you know about the Ice Cube Neutrino Observatory?" Ding Sheng and Song Lizhang had a detailed discussion about this "big trouble" while driving back to the new base in the Fourth Corridor.

Song Lizhang nodded and replied, "I know, it is funded by the National Natural Science Foundation of the United States of America and built the world's largest observatory near Amundsen Scott's Antarctic Station. ”

"This set of pulse signals is the source of the cosmic radiation signal received by the Ice Cube Observatory not long ago, and because the amount of calculations is too large, the United States has not yet had time to convert this set of signals, so so far, you and I are the only two people who know about this matter. Ding Sheng said solemnly.

Since it is a big trouble, it will definitely not be easy to deal with, and he needs some help.

And now, apparently, there is no more suitable helper than Song Lizhang and the scientific forces behind him.

"Wait... Then how did you get the information from the Ice Cube Observatory, and how did you convert the signal before the United States?" Song Lizhang was a little confused, he hadn't seen him for seven months, and as soon as Ding Sheng came back, he stretched out his hand to Antarctica, which was really long enough.

"That's not the point, the point is the next trouble for us, all of humanity, the whole planet..."

Of course, Ding Sheng can't say that he is always concerned about global security, nor can he say that the new base hides a quantum computer with the world's strongest computing power.

"Dean Song, this pulse signal keeps transmitting information to the earth at a subtle frequency, and observatories around the world will receive the same information for a period of time in the future. Based on the calculations in my hands, I'm sure I'm responsible for what I said, a pulsed signal from about 2.5 billion light-years away, created by intelligent beings, and transmitting information to our Earth, in other words..."

Taking another deep breath, suppressing the waves in his heart and the emotions on his face, Ding Sheng said solemnly, "There is an alien civilization that has discovered our earth coordinates." ”

Groov.

Song Lizhang's heart suddenly beat violently, this result is really unfriendly to an octogenarian.

For a moment, he also fell silent.

The existence of extraterrestrials in the universe has always been a hot scientific topic, and we have a fear of knowing nothing about extraterrestrial civilizations.

So if there is really a signal of a mysterious alien civilization in the universe, or even an alien civilization visiting, how should the earth deal with itself?

If it is really an alien civilization that has the ability to visit the earth, it is difficult to guarantee that the scene of Columbus's discovery of the American continent will not be repeated, and the earth is undoubtedly unsafe.

At the very least, security will not be in your own hands.

Long.

"Ding Sheng, I was thinking just now, you might as well not come back..."

With a small joke to transition the cold atmosphere in front of him, Song Lizhang chose to believe this young man.

"So, what can I do?"
