I asked you to write a light novel, but you wrote about living?

"The two sides in the war are the carbon-based federation and the silicon-based empire."

"During the 20,000-year war, hundreds of millions of stars and planets were destroyed, and countless civilizations were completely wiped out."

"In order to contain the silicon-based empire at the top of the first spiral arm of the galaxy, the carbon-based federation is preparing to build a 500-light-year isolation belt."

"Most of the stars within the isolation zone will be destroyed."

"The sun is among them."

Yu Yin immediately tensed up.

"And what about Earth?"

"If the sun is destroyed, the earth will not exist."

Yu Wen said.

After a long and brutal war, the Carbon-Based Federation began to re-examine the value of life.

Before destroying the star, they decided to first identify the civilizations within the isolation zone.

Civilizations that meet the Level 3 standard can be protected.

If it falls below the standard, it will disappear along with the star.

They originally believed that the first spiral arm of the Milky Way was a desolate region, incapable of harboring a sufficiently advanced civilization.

Until the scan reaches the solar system.

The Carbon-Based Federation discovered a large number of life forms on Earth and began conducting random site tests on human civilization.

They did not select the most advanced research institutions, nor did they select any scientists.

The scan, spanning 50,000 light-years, finally landed on that mountainous region in the northwest.

The impact fell on those children who had just lost their teacher.

The carbon-based federation copied the children's information, built a digital model, and then began asking questions.

What laws govern the evolution of life on your planet?

Why are stars able to release energy?

What molecules make up the liquid in the oceans of your planet?

The children were completely bewildered.

They don't even know what stars are, let alone understand what molecular and biological evolution is.

One question remained unanswered.

The second question remained unanswered.

The tests continued, but the children were still unable to provide answers.

The carbon-based federation has a decreasing opinion of Earth's civilization.

Finally, the commander in charge of establishing the isolation zone lost patience.

"We can't waste any more time."

"Destroy the sun."

A base point bomb powerful enough to destroy a star was launched.

Ten minutes later, it will reach the sun.

At that time, all of human civilization will turn into dust in the universe.

Yet no one on Earth knows this.

Some people are working, some are going home, and some children are just falling asleep.

No one knew that the entire civilization only had ten minutes left.

Yu Yin stared intently at her brother.

"Will the Earth really be destroyed?"

Yu Wen did not answer, but continued speaking:

"While waiting for the bomb to arrive, the governor of the Carbon-Based Federation decided to ask a few more simple questions."

"The children still can't answer."

The bombs kept getting closer to the sun.

Until the consul proposed:

What would an object's motion be like if it were not acted upon by any external force?

The children's previously blank eyes suddenly lit up.

They had just heard about this problem.

It was in that classroom without electricity.

Just before the candle beside the hospital bed went out.

The teacher who has passed away forced them to memorize it again and again.

So, the children, each with a heavy Northwestern accent, answered in unison:

"When an object is not acted upon by an external force, it will remain at rest or in uniform linear motion."

The governor of the carbon-based federation was shocked.

He immediately asked two more questions related to low-speed mechanics.

The children gave complete answers again.

Those were the three laws of mechanics that Teacher Li told them to remember in his last moments.

They do not understand these laws.

They are unaware that their answers are determining the life or death of all human civilization.

But they remembered what their teacher had taught them.

Word for word.

The advanced civilization on the warship finally realized that there was a civilization on Earth that had begun to understand the fundamental laws of the universe.

"Immediately change the direction of the base point bomb!"

The highest order was relayed throughout the fleet.

The bomb, which was already close to the sun, changed course, grazed the solar system, and shot into the boundless darkness.

The sun still burns.

The ocean did not evaporate.

The cities on Earth did not go out.

Yu Yin finally breathed a sigh of relief.

The carbon-based federation still has doubts.

Through more detailed observations, they discovered that humans do not inherit memory.

Every baby is born without any knowledge accumulated by the previous generation.

Human individuals can only communicate through language and writing, resulting in extremely low information transmission efficiency.

Moreover, human lifespan is extremely short.

Under normal circumstances, it would be impossible for such a species to complete a long period of knowledge accumulation.

When a generation dies, civilization should begin anew.

They cannot comprehend how humanity built civilization and began to understand the laws of nature.

Until a senator found the answer.

"Among human beings, there exists a special kind of individual."

"They are distributed throughout the population, acting as a medium for the transfer of knowledge between generations."

"The knowledge accumulated by the previous generation is passed on to the next generation."

"The next generation will stand on this knowledge and continue to move forward."

"Knowledge does not disappear with the death of individuals, generation after generation."

These people are called teachers.

As the last two words were uttered, Chen Jianjia's body trembled slightly.

teacher.

Compared to advanced civilizations that traverse galaxies and destroy billions of stars, this profession is so insignificant as to be almost negligible.

It is precisely these countless ordinary people who have enabled a race with short lifespans and no inherited memories to pass down knowledge from generation to generation.

A law discovered by a mind that died hundreds of years ago travels across time to a dilapidated classroom in a remote mountain village.

Then, a teacher who was so poor that he couldn't even afford to treat his own illness passed it on to a few children who couldn't even get enough to eat.

Finally, those laws, spanning 50,000 light-years across the cosmos, became proof that human civilization was qualified to continue existing.

Yu Wen paused here and slowly said:

The most incomprehensible thing about the universe is that it is comprehensible.

After a pause, he read the next sentence:

The most comprehensible thing about the universe is that it is incomprehensible.

The three laws of motion saved the solar system.

It was Teacher Li who got those children to recite the three laws of mechanics.

It's the teaching profession.

Teacher Li did not change that mountain village.

It did not immediately make the land rich, nor did it immediately lift the students out of poverty.

He died without ever knowing the ultimate impact of the knowledge he had imparted to his children.

But the tiny spark he ignited with his life ultimately proved the weight of all human civilization in the distant center of the Milky Way.

Yu Wen's voice gradually calmed down, and he uttered the last sentence of the story:

They will survive, and on this ancient, barren land, they will reap a meager but real hope.

There was silence in the living room for a long time.

Yu Yin, her eyes red, asked softly:

"Does Teacher Li know?"

"Know what?"

"Knowing that I saved everyone."

Yu Wen shook his head.

"have no idea."

"He died without ever knowing what use the things he taught his children would be."

Yu Yin remained silent for a while.

"But he still taught it."

"Yes."

Yu Wen said:

"He still taught it."

"Because he is a teacher."

Chen Jianjia lowered her head; her vision was already somewhat blurred.

A teacher may not be able to immediately change a child's current life, nor may they be able to witness the seeds they have sown taking root and sprouting.

But once knowledge is passed on, it will not remain confined to a classroom, a test paper, or the life of a single person.

It will be carried into the future by the next generation.

It may lie dormant for many years, or it may become a force that changes destiny and even saves the entire civilization at some unpredictable moment.

If an advanced civilization in the universe can easily decide the life and death of humans, then what will humans rely on to prove that they are qualified to survive?

This rural teacher in a remote mountain area has already provided the answer.

It is knowledge.

They are also those who pass on knowledge from generation to generation.
