Ye Weimin's brief but sonorous speech ended, and the audience was speechless.

But soon, with sporadic applause, the applause became more and more intense until it resounded above the teaching building.

As the applause gradually subsided, Hu Xingyao saluted Ye Weimin and hung up the call.

After the call is over—

Silence, boundless silence.

Everyone's eyes were gathered on Hu Xingyao's face, but at this moment, his face was extremely calm, as if the surging in everyone's hearts below had nothing to do with him.

Hu Xingyao waited for a while, but saw him take out a remote control from the multimedia and press it down.

All the lights in the classroom went out together, causing a commotion.

Hu Xingyao, carrying his hands on his back, said coldly in the shadow:

"Let's watch a video first."

The huge screen behind Hu Xingyao lit up.

A white figure appeared on the screen, accompanied by a narration:

"If aliens exist, then where are they?"

Chen Weifeng raised his head and watched the video curiously.

In reality, Earthlings have been developing into the interstellar era and no aliens have been found, so Chen Weifeng also wanted to know the meaning of this video.

At this moment, Li Mengfan, who was beside Chen Weifeng, suddenly came over and said softly:

"This video begins with the Fermi paradox."

"Fermi Paradox?"

Chen Weifeng felt Li Mengfan's warm breath and turned his head to look at her.

Seeing the doubt on Chen Weifeng's face, Li Mengfan smiled gently and explained in a low voice:

"The Fermi paradox elaborates on the contradiction between the overestimation of the existence of extraterrestrial civilizations and the lack of relevant evidence."

"Well... Simply put, humans can theoretically fly to various planets of the Milky Way in 1 million years. Then, on the other hand, as long as aliens evolved 1 million years earlier than humans, we should be able to see them now."

"But we have not found any evidence of validity in proving the existence of aliens yet, so there is a contradictory relationship between reality and theory, which is the Fermi paradox."

No, actually aliens exist, not only exist, but develop according to the timeline. In five years, they will destroy humans and occupy the Blue Star.

Chen Weifeng thought this way.

"But why should we raise the Fermi paradox here?"

He turned to look at the video, feeling a little strange.

What Chen Weifeng thought was also a lot of new doubts.

Then, in a dark video, one scene after another:

13.82 billion years ago, the Big Bang.

Four basic forces: gravity, electromagnetic force, strong nuclear force, and weak nuclear force.

400,000 years later, the cosmic background radiation.

The first batch of stars were born.

The first galaxies were born.

However, galaxies dominated by hydrogen and helium do not have the basis for the birth of life. Only on the basis of heavy elements formed after the star collapses can life and civilization be born.

The video flashed faster.

"4.57 billion years ago and 4.54 billion years ago, the solar system and the Blue Star were born respectively."

"3.5 billion years ago, the origin of life in the ancient universe."

"570 million years ago, Paleozoic vertebrates."

“225 million years ago, Mesozoic reptiles.”

"70 million years ago, the Cenozoic Mammals."

“…”

"After the Quaternary period, humans formed."

Seeing this, many people still have doubts:

"What exactly does this video mean?"

Then, a question that occupies three-quarters of the length of the screen appears in the video:

"Is human beings really the only one?"

After that, the viewing angle of the video is increased, while the names and numbers below the screen are constantly changing:

"Solar system, star order of magnitude: 10^0."

"The Milky Way, the order of magnitude of stars: 2*10^11."

"Observable universe, the order of magnitude of stars: 1*10^21."

After a brief stop, the sentence appeared on the screen again:

"Is human beings really the only one?"

Long before the Federation, Blue Star biologist Dirk Skuz of Marika had identified more than twenty exoplanets that might be more beneficial to life than Blue Star.

Through transit method and Doppler spectroscopy, there are 11 billion potentially inhabitable earth-like planets in the Milky Way alone. If a large number of red dwarfs are counted, this number will rise to 40 billion.

Just in the Milky Way, exoplanets that may appear in life have reached this order of magnitude. So among these large number of exoplanets, how likely is it to be a civilization?

Is Blue Star really that special?

But the question goes back to the original Fermi paradox:

If alien civilizations really exist, where are they?

After thinking, the students once again focused their attention on Hu Xingyao, hoping to learn about his purpose of playing this video.

Hu Xingyao waited for a long time, and when more and more students focused their attention on him, he coughed lightly and said seriously:

"I don't know whether there are other civilizations outside of Blue Star. However, during a global exploration decades ago, scientists discovered a stone tablet in the Great Rift Valley of Avkazhou, which recorded a strange way of practice. According to research, this method of practice does not belong to Blue Star."

"After a long period of research, we call this practice—"

“Mechanical practice method!”

Hu Xingyao wrote these five big words heavily on the blackboard, then he turned around and continued:

"In the next four years, in the Super Time and Space Academy, all your studies will be based on the mechanical practice method."

"Mechanical practice is a powerful force. By tempering star energy, condensing star species, completing mechanization, and mastering mechanical practice, one can mechanize the whole body and become a mechanical warrior."

"Being an excellent mechanic warrior is the goal you will strive for in your future life."

Hu Xingyao has already said it very clearly. Without fools here, it is impossible for him to not understand.

But some words quickly rang out in the classroom, probably some denied words.

They didn't believe what Hu Xingyao said, even under the endorsement of Ye Weimin.

After waiting for a while, Hu Xingyao ignored the commotion that sounded in the classroom, but turned around and wrote two words heavily on the blackboard, and said:

"Star energy."

"This is the most core force in the universe, with the characteristics of life energy."

"If you want to become a mechanic warrior, you must master the application of star energy."

Speaking of this, Hu Xingyao turned his head and asked the new students:

"You want to know why the Super Time Academy chose you?"

The freshmen raised their heads in unison.

Although most people have not believed what Hu Xingyao said, they also want to know what exactly made them selected by the Super Time and Space Academy and have to come here.

What exactly is it...
Chapter completed!
