In the darkened interrogation room, three people sat opposite each other, and the only light available was a lamp on the table.

The two inquisitors stared at the person sitting across from them with grim faces, as if they were about to reveal all the secrets of the interrogator in front of them from the inside out.

One of them was the first to break the silence.

"Billen, a native of Introspection, was raised by his grandfather after his parents died in an accident at a young age, graduated from the National School of the Revolution in 1750, and joined the Astronomical Observatory 804 after graduation, during which he published many observations of new stars......"

"Due to his outstanding performance, he was assigned to join the 'Cosmic Voice Project' when he was on the wheel in 1788 and participated in the national mission to search for extraterrestrial civilizations......

"In 1805, Wheel, as the first discoverer, discovered the existence of an alien civilization named Amoeba in the Sutton cluster B five light years away from us, and successfully established contact with the other party......"

"The 1815 Wheel was dismissed for sending signals to the outside of the star system without permission, and was lost until 1834, when the Wheel was arrested and imprisoned for allegedly joining the Equality Organization during the census."

After speaking, the inquisitor looked coldly into the eyes of Biron, who was sitting opposite, and asked.

"Is there anything you need to add?"

"Nope."

Billon shook his head, his face unchanged, not in the slightest bit overwhelmed by the inquisitor's momentum.

"Can you tell us what you're hiding?" The inquisitor asked.

Hearing this, Billon sighed, this is not the first time, he has already explained all the information he has obtained from the amoeba civilization very well.

No matter how much he tried to extort confessions with words and deeds, coercion and inducement, he couldn't say anything.

"I know, you know, I have nothing to hide."

"We want to know, what is the level of technology of that amoebic civilization?" The inquisitor continued to ask.

"I don't know about this, Amoeba didn't reveal more information related to civilization."

Billen said he didn't know anything as he had done before, and another colleague next to the interrogator, who had remained silent, slammed the table and stood up, snorting with a hideous face.

"But you have to know something! You brought them in! You've betrayed all the Carters on Solhi! ”

"Don't get excited, sit down first." The inquisitor said.

The colleague looked at the inquisitor, glared at Billon like a cannibal, sat back down, and warned Billen with gritted teeth.

"You'd better tell everything you know, or I'll do everything I can to pry it out of your mouth, believe me, you'll regret it at that time, why didn't you say it earlier."

One sings with a white face and the other with a red face, very simple interrogation skills, Billon doesn't know very well, but he also occasionally hears about it, and his heart is still unfazed, after all, he is not even afraid of death, what else will he be afraid of?

Seeing that it didn't work, the inquisitor stopped trying to use this method, but instead looked for loopholes in Billon's words and got to the bottom of it.

"Since you don't know the skill level of amoeba, why are you sure that amoeba has the ability to cross five light years to reach our side? You must have a basis, right? Can you tell us? ”

"Yes, I have a basis, relying on that I can vaguely understand what level of amoeba civilization is."

Billon admits that because there is nothing to hide, this information can be obtained from other sources, but the government has not yet collected information in that direction.

"Speak quickly!"

The interrogator's colleague slammed the table and continued to shout loudly.

"At a scientific seminar, someone asked the question, if there are many extraterrestrial civilizations in this universe, how should these extraterrestrial civilizations be classified?"

Billon throws up such a question in the middle of the story, and then throws out the answer to the question.

"Then, based on this problem, some people put forward three levels of cosmic civilization, the first level is the development and utilization of the height of the home planet where they live, the second level is the development and utilization of the height of the mother star they live in, and the third level is the development and utilization of the height of the mother river system where they live."

When Billon finished speaking, the loud-voiced inquisitor began to inquire in a hurry.

"So what level of civilization does our civilization belong to? What level does the amoeba civilization belong to? ”

Billon thought for a moment and answered his question, "The Carter civilization belongs to level 0.6, and the amoeba civilization may be at the second level. ”

"Why are we 0.6?"

The inquisitor inquired in confusion, the two of them did not know as much about science as an academic member like Billen, and in their opinion, the current Carter civilization had a high level of technology, and after researching nuclear weapons, their civilization already had the power to destroy the world.

Although the amoeba civilization seems to be stronger than the Carter civilization, in their minds, even if the gap is large, it is the kind of gap that the Carters can catch up.

"This is based on the overall energy output value of the Carter civilization, and we imported the calculation formula to get the results, and we also hope that the results can be higher, but we can't."

Billon explained the origin of this value to the two inquisitors.

"We've developed nuclear weapons, and nuclear power plants will be able to produce a lot of electricity in the near future, so what would be the result?"

The irascible inquisitor continued to ask, but Billon's answer made him feel bad.

"It's 0.6, and the academic members who hope that the value can be higher have deliberately taken into account the technology that will be put into practical use in the near future, otherwise the value will be lower."

As soon as these words came out, the interrogation room fell into a short silence, and an inexplicable emotion emerged in the hearts of the two interrogators, which I couldn't say, but it was just very bad.

After quickly adjusting his emotions, the interrogator continued to ask.

"You just said 'maybe', which means that you are not sure, so on what basis do you think that the amoeba civilization belongs to the second level?"

Since the level of Carter civilization is calculated through mathematics, what is the basis for the calculation of the level of amoeba? The inquisitor was keenly aware of this.

"According to the way the amoebic civilization feeds back information, they are interstellar information transmission by allowing stars to change their brightness in the visible spectrum, which is consistent with the description of the second level." Billon replied.

However, Billen's answer did not satisfy the Inquisitors, who questioned loudly.

"What are you talking nonsense? The stars twinkle like the lights of a car in the night sky, and it's a big event that makes headlines the next day, and you can't be the only observer! ”

"This change in brightness is difficult to detect with the naked eye, but it is evident in high-precision astronomical instruments – the star is transmitting information by 'blinking'." Billon replied.
