After listening, Chen Feng fell into a long silence.

He forgot to keep walking, and stopped on the road with his hands in his pockets.

He looked up at the willow tree above his head.

The wicker swayed in the breeze, and a few young green sprouts hung from it.

This is the last time before the last rebirth.

Chen Feng narrowed his eyes, and the story of the predecessor of the Xuanwu Academy that Ding Hu said was repeated in his mind.

He felt deep sorrow for those who were born in this era after a thousand years.

I've tried so hard, but I still can't change anything, it's still in vain.

One hundred years ago, that is, in the early twenties of the twenty-ninth century, the level of human science and technology fell into a bottleneck.

During this period, there was no progress in science and technology for a whole decade.

Materials and energy are the foundation of all scientific progress, in order to break through the bottleneck, the world government gathered the best scientific research talents in all related basic disciplines at that time into one base, and went all out to make breakthroughs.

I didn't want to tackle this problem for 83 years.

Four generations, a total of 1.37 million people, walked side by side on this extremely difficult and thorny road.

Day after day, year after year.

In the 29th century, when medicine was extremely prosperous, the average life expectancy in the world had already exceeded 100 years.

But the average life expectancy of more than 1.3 million scientific researchers who enjoy the best welfare benefits is less than 60!

More than 600,000 people died of overwork who did not live to the age of 50.

They always burn out the last drop of wax when they are at their most energetic and clear-thinking.

Even when they collapsed on the hospital bed, before they took their last breath, they still had the work materials in their hands.

Their last words were all to hand over their unfinished projects to their successors.

In the past 80 years, more than a million people have fallen one after another, but no one has flinched.

This is a war without gunpowder, but with corpses everywhere.

In the end, humanity won the war, making a breakthrough twenty years ago.

It took another twenty years for humans to transform their achievements, and the external manifestation was that Type 3 was replaced with a more advanced spindle-shaped vehicle, and the bloated and clumsy old individual armor was replaced by a lightweight and efficient Qinglong armor.

Chen Feng's reversal of Ou Junlang's fate left an introduction.

The change of Ouhe Group is an amplification of Chen Feng's changes in the future.

On the basis of the predecessors, the predecessor of Xuanwu Academy, on the basis of the predecessors, once again amplified the butterfly effect during the eighty-three years of desperate charge.

In the end, countless causes converged into one fruit, allowing mankind to win a scientific and technological war, complete a phased qualitative change, and form the current status quo.

With Chen Feng's worldview, he really didn't understand how these people persevered.

What kind of beliefs are sustaining them?

And how did the world government convince scientists to be willing to sacrifice themselves in this way to deal with an illusory but doomed enemy?

Chen Feng was puzzled by this.

But his greatest strength is that he never bothered to think about things that he couldn't figure out.

He can easily judge the boundaries of his ability, never drill the horns, and resolutely give up pondering.

As for why "Bathing in Fire" has become a war song for mankind, it is inseparable from this group of scientists who interpret self-sacrifice to the extreme.

Those people worked an average of more than 16 hours a day, and even if they had firm beliefs, they could recover their physical fitness with nutrition, but they were still mentally exhausted when they were in a state of high brain load for a long time.

They also need some mental stimulation.

At first they used medication and psychological counseling.

But the essence of the drug is to overdraft in advance, and after enjoying the dividends of the drug, you will soon have to pay off the debt.

Counselling is too slow to take effect, and precious time cannot be wasted.

So what to do?

Scientists have come up with many ways and made countless attempts with new technologies, but with little success.

Later, I don't know who was the first to open the dust-covered pile of old papers, and found the bright night pearl in the precipitation of countless histories.

The famous song "Bathing in Fire", which was born thousands of years ago, once again resounded in the sky.

Zhong Lei, a generation of famous artists who fought iron for a thousand years, and even sat on the top ten, although has never been forgotten, there are new people from all over the country, and people's hearts are always impetuous, except for a few lovers who like "ancient style and ancient rhyme", others rarely listen to the songs of thousands of years ago.

But this time, the first person in this group of scientists to eat crabs had the mentality of giving it a try to see if he could find enthusiasm in the song, and then listened to "Bathing in Fire".

The emotions in this song perfectly match the state of mind in his heart at this time, which is burning and sacrificing for the survival of mankind.

He burst into tears and remained in perfect spirits for the whole day.

The next day, he continued to listen.

He had thought that the efficacy would be reduced, but the second time he listened, he would become resistant and numb due to repetition.

But no, the state is still so good.

On the third day, it was the same.

It lasted for a whole month, and the effect was still not compromised.

This is a big man who has achieved a lot in the field of acoustics in addition to the field of materials science, and he has made a technical and comprehensive analysis of "Bathing in Fire".

Eventually, he came to the conclusion that when a person's own state of mind perfectly matches the mood in "Bathing in Fire", the efficacy of the song does not diminish, because the song represents the ultimate sound that human beings can create on a certain level, from accompaniment to singing.

Its melody is less like an artificial creation, but more like the human genes that nature has prompted the evolution of genes, and finally put together them with incredible ingenuity.

This person recommended "Bathing in Fire" to a good colleague, and then spread it to hundreds of hundreds, and quickly became a common hobby of hundreds of thousands of people throughout the research institute.

"Since then, the progress of the entire project team has been greatly accelerated, but because of this song, more people have exhausted their efforts in advance and died of overwork."

"It's not that "Bathing in Fire" hurt everyone. Take a certain scientific researcher as an example, he originally took 80 years to complete the work, but with the stimulation of "Bathing in Fire", he completed it in only 40 years. ”

Although he eventually died early at the age of sixty, he did the best he could in his life, and his life was without regrets. His name will also be remembered forever by mankind. ”

"Master Zhong is no longer a leader in the art world in the narrow sense, and it is no longer possible to summarize her achievements and contributions in terms of rankings."

"Her work, thousands of years later, can inspire entire generations and allow us to complete this technological advancement. Her achievements will forever shine on the monuments of civilization. ”

"Chen Feng, have you seen that bell tower? The bell tower was engraved with the names of 1,376,432 men. The names of Master Zhong and her enlightenment mentor, Master Chen, are all the scholars who died in the former base of the Xuanwu Academy, from top to bottom. ”

"It's a bit of a coincidence, Master Chen's name is exactly the same as yours. You're also the first person in human history to have 100 percent coagulation serum fitness, and you're amazing. ”

"It's like it's predestined. Should I change my name to Ding Feng? Ha ha...... Hiccup......"

Before sending Chen Feng to the Qinglongjia training compound, Ding Hu said.

Chen Feng wandered alone in the compound for a long time, and then stood at the corridor and looked at the bell tower in the distance.

The scorching sun in the afternoon scorched his eyes, and Chen Feng turned his face away and didn't dare to look at it again.

For a moment, he wanted to go to the bell tower to see his name.

But in the end, he didn't take a step, just turned his back and walked quickly into the building to meet the Blue Dragon Armor trainer who came to greet him.

Something more in my heart.

It's heavy.

It almost took him breathless.
