When the plane rose, Zhong Zixing looked at the sky outside the window and was stunned, and Li Donghui, who was traveling with him, did not speak.

When I arrived at the Beijing airport, it was already noon.

Before the condolences began, Zhong Zixing first went to Tsinghua University to visit the teacher who taught him, and then found a hotel with Li Donghui to stay.

Waited silently for two days.

At the beginning of November, the weather was even more gloomy than the previous two days, and a cool breeze was blowing, which seemed to be seeing off Mr. Qian.

Zhong Zixing joined the memorial procession formed by the students spontaneously, holding a long strip of black cloth and rushing all the way to the Babaoshan Cemetery.

The drizzle in the sky did not stop the people who came to see them off, and although the crowd was crowded, no one spoke.

Students from all over the world, teachers from major universities, and scientific researchers from the two academies almost all obeyed the order, lined up in long lines, and stretched to distant places that could not be seen by the human eye.

More and more people who knew about Qian Lao's death arrived, and slowly gathered into a send-off procession of hundreds of thousands of people.

The soldiers opened the way in front to maintain safety, and the whole army honor guard carried the old man's coffin to the cemetery where he could be buried only if he had made a great contribution to the country.

Many of China's founding fathers, generals with outstanding military achievements, and accomplished scientists are buried here.

The cries of Qian's relatives came, and the sadness began to permeate, gradually infecting everyone who came here.

The scientists in front bowed their heads and said goodbye to this pioneer on the path of science.

......

"Zixing, come here!" Professor Qiu Yong from Tsinghua University of Science whispered to Zhong Zixing.

"Teacher, you're here too?"

"Go and put on a stick of incense,......" Professor Qiu Yong didn't say much, patted him on the shoulder, and handed him a stick of incense that had already been burned.

Zhong Zixing took it, walked in line to the tombstone, bowed respectfully, inserted the incense in front of the tomb, and then retreated.

"How short is life?"

Seeing the people he admired disappearing into the world one by one, leaving only his life deeds to spread, the scientists in the front row began to think about this question.

To be honest, it's hard to answer.

If you compress the history of the earth for nearly 5 billion years into 24 hours a day.

Then it took more than 4 hours for the birth of the first single-celled life alone, and it took 4:10 a.m. for it to emerge in the ocean.

After that, it took more than ten hours to conceive and reproduce, and it took more than ten hours to promote the process of life, and at 9:13 p.m., the first Cambrian explosion of life was ushered in, and at 9:50 p.m., life began to land from the ocean, and slowly evolved walking legs.

At about 10:49, the dinosaurs slowly stepped onto the stage of history, and after nearly 50 minutes of reproduction, they began to become extinct at 11:39 at the end of the day.

The end of the age of dinosaurs did not break the evolution of organisms, and animals evolved from oviparous to viviparous, and creatures with larger brain sizes appeared on Earth.

From Australopithecus, Australopithecus, Homo sapiens, Homo erectus, and Homo sapiens, the initial veins of human development were formed.

It wasn't until the last seconds of the day, at 23:59:56, that humanity was born.

Compared with the scale of the earth, how small and short is human beings? From the barbaric society to the emergence of a high civilization, it only took the last 4 seconds of the earth's development.

The average lifespan of human beings is less than 100 years, and thousands of years of civilization are indeed small and short compared to the development of the earth in billions of years.

But it is precisely because of the insignificance and transience that human beings will chase greatness, immortality,

"Compared with the earth, the vast universe is more desirable!" Zhong Zixing raised his head and let the raindrops hit his face.

"If a small human wants to explore the universe, the level of science and technology needs to be improved by several orders of magnitude!"

If you want to wander the infinite and distant universe, a spaceship is indispensable.

In order to truly enter the universe, we must first develop materials that are resistant to radiation, high temperature and low temperature, and meteorite impact, and have higher strength.

The second is the industrial level, which must be very precise and able to make some parts and key parts of the engine.

With the engine, then the exploration of efficient energy is on the agenda, and the conversion rate of mass to energy must reach at least 0.7% of the degree of nuclear fusion, at least.

Long distances are inevitably accompanied by long voyage times, so biotechnology must also make breakthroughs, cryonics technology, or simply let human life reach a long time that can be supported.

This is not enough.

Because in space, it is impossible for people to drive without resting all the time, so the autonomous spacecraft in information technology, calculating the navigation route, and assisting the operation of artificial intelligence must be installed, which is the easiest for Neutron Star Technology Group to achieve.

There is also ultra-long-distance barrier-free communication technology.

Supported by super-intelligent precision integrated circuits.

3D printing technology, all simulation technology.

Gravitational or magnetic field generators, complete biospheres on spaceships.

Thinking about it this way, if you really want to achieve space roaming or interstellar colonization, the technical requirements may be ridiculously high, and it is not at all possible to solve the problem by directly building a spaceship.

With the overall technology of the earth now, to say that it has not touched the corners is to belittle the overall wisdom of human beings, but strictly speaking, it has only touched a corner.

Finally, with a deep bow to Qian Lao's tomb, Zhong Zixing wiped the rain from his face, and followed the teacher to gradually leave Babao Mountain.

"The academic exploration of neutron star science and technology points out the direction, information technology solves the problems of automation, intelligence, and communication, liberates the productive forces, and the origin of matter is in the study of new materials, and sooner or later there will be materials in line with interstellar navigation, and the next department ......"

He saw that the people he admired most could not resist aging, death, or disease, and he had already made a plan.

Zhong Zixing wants to establish the Department of Life Code.

At present, the R&D consumption of the Material Origin Department is too large, and if you want to invest in R&D on a larger scale, you must have an incomparably large flow of funds.

Although the information technology is very strong, the scene has just been rolled out, and it can only provide funds for the material origin on a small scale, and the capital chain has been broken several times in a row these days, relying on subsidies from the town government to get through the difficulties.

And once the micro-integration department for designing semiconductors is established, and the extreme precision department for improving the industrial level, it will make people's heads explode.

Where to get the money? I can't grab that much.

The only way Zhong Zixing could think of was to rely on the Life Code Department to break through and develop a special medicine that could cure terminal diseases.

But the problem comes again, not to mention the time and funds for R&D investment, even if you really research a drug and want to make money on the market, you must go through various clinical experiments, collect no adverse reactions from patients when you eat it, and so on.

This process can be as short as three or five years, and as long as ten or eight years, there is no end in sight.

"Unless, unless, there really is a drug that others can't refuse, or even don't want to wait." Zhong Zixing sighed.

It's really hard to do research.
