Chapter 257 Liu Qin’s legacy

After hearing what Liu Xiu said, Lao Shi Zhang truly understood that Liu Xiu really planned to immigrate to Mars and turn Mars into his own home.

And what Liu Xiu said is correct, because it has only been 20 years since its establishment in 1969, and the population has more than doubled.

There was no way, Sui Rang Liu Xiu was a time traveler, so he took measures to store grains in advance!
The original three-year disaster turned into three years of construction, and the water diversion project was carried out decades in advance. As a result, in recent years, thanks to the support of water sources from the south, Peryonbian no longer has to worry about water for irrigation and agriculture.

Therefore, the food supply has naturally increased in recent years, and even because Liu Xiutai boasted about the space seeds produced at the station, the food production has been further improved.

In this era, not to mention rural people, they are city people. After eating, they watch TV and then have babies.

This is especially true in rural areas. There is no Internet and there is no way to use mobile phones. Apart from watching TV, the natural thing is to have babies.

Moreover, what this era advocates is that there is strength in numbers, and coupled with the traditional tradition of population prosperity, it has increased the people's desire to create babies.

Therefore, according to this growth rate of doubling the population in twenty years, in another twenty years, it will definitely reach 2 billion.

Naturally, such a population growth rate cannot be sustained based on the current land area. Therefore, interplanetary colonization is the only way to explore the interstellar world, otherwise there will only be war.

When Liu Xiu saw Liu Qin like this, he couldn't help but feel distressed and said:

Knowing that Liu Xiu had a long-term vision, Lao Shizhang stopped urging Liu Xiu. Instead, he said to Liu Xiu:
"Yes, your vision is far-sighted than ours! You have already considered what will happen twenty or even fifty years from now. In this case, you can go ahead and do it boldly! We old guys will support you under the pressure. Don’t worry, we will support you as always! The future is yours!”

"Thank you, Old Lion Tent, for your trust! I will definitely make sure that Mars immigrants are able to open up a new living space for crops and people!"

Liu Xiu was immediately shocked when he heard the news, and then he no longer bothered to watch the manned launch. After all, it had been launched so many times, and there was nothing new anymore.

And Liu Xiu’s father, Liu Qinna, has been father and son with Liu Xiu for more than thirty years!
He was also the biggest driving force behind Liu Xiu's success. After all, if Liu Qin hadn't invented the cricket plane, Liu Xiu's achievements would have been the same as Li Yunlong's, just as a military accountant!

After Liu Xiu left Lao Shi Zhang's office, he originally planned to go to the space launch pad to watch the 56th manned space flight. However, at this time, Liu Xiu suddenly received a report that his father Liu Xiu Chin passed out in the laboratory of his detonation engine.

So Liu Xiu came to the hospital immediately and saw Liu Qin lying on the hospital bed with white hair, a yellow face and thick dark circles under his eyes.

After all, he is not like Liu Xiu, who is in his prime in his thirties. No matter whether he has energy or other things, he can't work as long as before.

After Liu Xiu made this promise, Lao Shi Zhang waved his hand and let Liu Xiu go. In fact, Lao Shi Zhang was already over seventy years old, so now Lao Shi Zhang is in a semi-retired state. Except for key matters, general The old lion's account no longer interfered much.

However, under the supervision of Su Zhao and Mi Zhao, even if the army is strong and it wants to expand, it is impossible.

Because Mi Zhao and Su Zhao couldn't allow this place to expand unbridled.

"Dad, why are you doing this! Why are you obsessed with this pulse detonation engine! Wouldn't it be better to have a safe and secure retirement?"

Yes, although Liu Xiu is only thirty-six years old this year, Liu Xiu can be regarded as Liu Qin's old son!
Liu Qin did not get married in order to study abroad, so he waited until he was in his thirties before getting married and having Liu Xiu. So now Liu Qin is already seventy-two.

But because Liu Qin now works overtime almost every day in the laboratory to study his pulse detonation engine, his current body is not that good. After Liu Qin heard Liu Xiu's words, he sighed and said:
"Xiu'er! You don't understand the persistence of a real scientific researcher. I, Liu Qin, have been engaged in scientific research for so many years, but up to now I don't have a single invention that I can use. I just optimize the inventions of others, so my kind of Can you understand this?"

When Liu Xiu heard this, he said:

"But Dad, you have been researching your detonation engine since before the Anti-Japanese War. It has been almost fifty years now! And there is still no progress at all!"

However, when Liu Qin heard Liu Xiu's words, he immediately said excitedly:

"Who said I haven't made any progress? If I didn't make some progress, would I faint from exhaustion?"

With that, Liu Qin explained to Liu Xiu the research progress of his pulse detonation engine.

It turns out that the pulse detonation engine developed by Liu Qin is already operational.

However, the operation is not very stable, and flameouts often occur. The main reason for this is that the fuel supply is not very stable and the ignition is not timely, so the continuity and size of the explosion wave are also unstable. This will naturally make it easy to turn off the flame.

Now Liu Qin wants to find a way to control the fuel supply and ignition time of the pulse detonation engine with microsecond-level control at all times.

When Liu Xiu heard this, he couldn't help but think of the electronically controlled ignition engines of later generations.

With the development of electronic technology, the original purely mechanical cars began to incorporate electronic structures, such as electronically controlled fuel injection, while for gasoline cars, electronically controlled spark plug ignition is used to improve ignition time and timely combustion.

Therefore, cars with the same displacement and electronic fuel injection can save more than 20% in fuel compared with cars with mechanical carburetors.

Although there is no such car on the market now, the integrated circuit developed by Liu Xiu can easily do this.

Yes, because Liu Xiu knows that the future is the era of integrated circuits, Liu Xiu still invests a lot of research and development funds in integrated circuits.

It’s really because of the investment that Liu Xiu’s electronics industry is the most mature in the world.

So in order to be able to use pulse detonation engines in his space station, Liu Xiu also put down his work and started studying pulse detonation engines with Liu Qin when Liu Qin went to the research institute again.

And after Liu Xiu applied electronic injection technology to the pulse detonation engine, the pulse detonation engine that originally stopped at every turn could start running easily.

Liu Qin burst out laughing after seeing that the pulse detonation engine could run smoothly for an hour.

But with this smile, Liu Qin started to have nosebleeds while smiling.

Then Liu Qin's body began to stagger, as if he could not stand firmly. Seeing this, Liu Xiu quickly helped Liu Qin, and then began to call the doctor.

However, Liu Qin suddenly grabbed Liu Xiu's hand and said to Liu Xiu:
"I know that I may not be able to survive, but if I can successfully research the pulse detonation engine, I will be satisfied and die without regrets! I know that you will definitely use this pulse detonation engine on the space station, so can you take my ashes with you? Buried on Mars!"
