Start sweeping the universe by rubbing the CPU with your hands.

On the big screen, headed by the head of the Hematite civilization, a group of high-level civilization officials with metallic faces were all sitting in a metal-style hall with serious faces.

"One hundred thousand battleships to assist our friends."

He didn't even ask why humans chose to participate in such a high-risk galactic cleanup operation.

Han Yang expressed his gratitude again, repeated the words he had communicated with Ziyun Civilization before, refused direct warship assistance, and then said: "If possible, you can send some engineers and technical workers from your civilization."

The leader of Chitie said directly: "Okay. One hundred million, it will arrive in nine years."

After that, communication was cut off directly. The whole process took less than five minutes, and Han Yang felt a sense of loss, as if the phone was hung up before he finished speaking.

If we remove the fact that Ziyun people think we don’t wear underwear, it would still be more pleasant to communicate with Ziyun Civilization...

At least, when I expressed my gratitude, the Ziyun people would still say a few polite words to me...

After deciding to accept assistance from other civilizations, but only in terms of social production, the other three civilizations in the Sun Alliance also acted in accordance with the law.

There is nothing to say about these three civilizations. They are all their own territory. It doesn’t matter what Han Yang says. There is no need to discuss it at all.

Of course, you still have to do things to save face, and Han Yang must also follow the corresponding etiquette.

Soon, these three civilizations also finalized plans to support 3 million, 2.6 million, and 2.5 million engineers and technical workers respectively, and to increase civilization exports through human currency settlement.

Calculated based on the productivity of a Level 2000 civilization, this total of more than one billion engineers and technical workers is enough to produce all the resources and products needed for the daily lives of the entire human civilization, a total of more than billion people.

Food, clothing, housing, transportation, drinking water, medicines, industrial products, textiles, interstellar transportation, and even city operation, maintenance, garbage disposal, facility construction, etc., etc., all included.

In this way, Han Yang was finally able to organize all the power of the entire civilization, including his own computing power, and devote it to two undertakings.

Military and science.

Go all out to produce warships and combat supplies, go all out to produce energy cannons, propellers, various shipboard instruments and equipment, and energy sources, go all out to recruit and train troops, and go all out to carry out galaxy cleanup missions.

At the same time, all scientific forces will be organized, go all out to analyze existing scientific and technological data, and go all out to promote scientific development.

In a maximum period of no more than 400 years, the civilization will achieve a breakthrough from level three to level four.

Because it still needs to be set aside for at least two hundred years to transform scientific and technological achievements and truly transform breakthroughs in basic theory into combat effectiveness.

If there is still no breakthrough within 400 years, then no one else has to blame.

"The matter has come to this, and we have no way out. Compatriots and comrades, let's fight!"

In a public speech, Liu Yuan solemnly announced the resolution.

With the introduction of this overall decision, the entire human civilization has truly entered a state of going all out.

Huge factories one after another are springing up like mushrooms after a spring rain, popping up on every planet in the solar system and on every planet in the surrounding galaxies.

Countless natural resources were mined and then transported to factories for further processing.

There was a long queue in front of the recruitment point. Countless young people with high aspirations and high morale vowed to join this journey of fighting for the future and destiny of civilization.

Once selected, the whole family celebrates with great joy. Once you lose the election, you will be devastated.

Among the more than 1500 billion human beings, excluding the young, seriously ill, and those who are incapable of working, the total labor force of more than billion is like clockwork, and they are fully devoted to this struggle.

This time, Han Yang did not plan to invest his computing power in military operations, but instead left it all to human warriors.

Because technological breakthroughs are more important than military operations.

Breaking through to the fourth level of civilization within 400 years, even if Han Yang went all out and devoted all his computing power, it would be as difficult as climbing to the sky. Under such circumstances, he really had no time to care.

At the same time, Han Yang also believed in his fellow humans.

For many years, mankind has never given up its emphasis on military affairs. Even in peacetime, investment in military training, military technology, and military theory has not been relaxed.

One after another, amazing military geniuses were born, promoting the continuous advancement of human military science. Loyal warriors were trained one after another and devoted themselves to the journey of defending the interests of civilization.

"This time, I, and we, have to go all out."

Han Yang thought silently.

The year after Han Yang announced that he would start a national struggle journey, the first civilization to support mankind arrived.

The 2.5 million engineers and workers of the Motan Civilization arrived on the space carrier of the Luotu Civilization.

Han Yang led all the ruling committee members to extend a warm welcome to these Motan people. Subsequently, these 2.5 million Motans were added to various positions required to maintain the operation of human civilization.

After that came the Fix civilization, and then the Yuanshan civilization. Han Yang also gave a warm welcome ceremony. Hundreds of millions of human beings who originally held these social positions were mobilized and replenished in the military and scientific industries.

In the ninth year after that, the Hematite Civilization team arrived as promised.

Regarding the arrival of the Hematite Civilization, although the welcome ceremonies of human civilization were of the same specifications - all of them were of the highest quality, from the bottom of his heart, Han Yang still valued the Hematite Civilization and the three civilizations of the Sun Alliance more. Ziyun is more civilized.

Those three civilizations are just his younger brothers, and the so-called warm welcome is just a matter of etiquette. The Hematite and Ziyun civilizations are their allies.

Allies and little brothers are obviously different.

Fully 100 million Hematite engineers and technical workers came to the city built specifically for them.

An environment completely suitable for the survival of Hematite people has been created here.

They will live here temporarily, and will later travel to different galaxies and different positions according to needs. But you have to wear a spacesuit when you leave here.

Of course, level three civilizations are technologically advanced, and the spacesuits they produce are light, close-fitting, beautiful and comfortable, and will not feel cumbersome even for daily wear.

In Hematite City, all human ruling committee members came forward and also gave a warm welcome ceremony to Hematite Civilization.

A group of representatives of the Red Iron Man were invited to the auditorium, each sitting at attention. On the stage, outstanding artists among mankind gave wonderful performances one after another.

In order to avoid accidents, the human side also specially learned about the preferences of the Red Iron people, and strived to fit the taste of the Red Iron people while showing the characteristics of human art as much as possible, and resolutely avoid inadvertently violating the taboos of the Red Iron people. things.

But no matter how meticulous the preparation team was, the accident eventually happened.

Everything was going smoothly. Although the Hematite people all had livid faces and were slightly uncomfortable, it was obvious that they were quite satisfied.

The accident happened at the end.

During this stage, several representatives of the Red Iron Man were invited to the stage, and then the human boys and girls presented wreaths of flowers to express their gratitude to the Red Iron Man for traveling across the star sea to help human civilization.

At that time, seven red iron men were invited to the stage, and something was wrong with their bodies. They seemed to be shaking, and they didn't know why. But nothing could be seen from their expressions, so the human preparation team did not stop.

Until the first Hua Wei was put around the neck of the Red Iron Man representative by the enthusiastic and sincere human boy, the Red Iron Man suddenly rolled his eyes and fainted on the stage.

This was a big deal. For a while, the red iron doctor, the human preparation team, etc. were in chaos, and the welcome ceremony had to end hastily.

"What's going on? Do you understand?"

The leader of the welcome ceremony preparation team was very anxious and his face was covered with sweat.

Liu Yuanyuan personally expressed concern about this matter! Things are getting big!

It was originally a welcome ceremony, but it ended up knocking out the distinguished guests who came to help us. What the hell is going on!

"Check it out, check it out!"

A team member rushed over and hurriedly reported: "We have communicated with the Red Iron medical team. The Red Iron representative is overloaded."

"Overload?" The team leader was startled, "What the hell?"

"The emotional center in the Red Iron Man's head is very underdeveloped and cannot withstand too strong an emotional impact. Our welcome ceremony was so, so good. As soon as the Red Iron Man got excited, he just went there..."

What the hell!

The leader of the preparatory team thought a lot and thought about every possibility, including the possibility that someone secretly poisoned the welcome ceremony, but he never imagined that the truth turned out to be this.

All the people looked at each other.

"Our welcome ceremony was well organized, but why did it go wrong?"

"No wonder those red iron men always look cold. It turns out there is something wrong with their heads..."

"I dare not say that! If others hear it, be careful of causing a diplomatic dispute!"

"Hematite people are here to help us, we can't slander them!"

After the incident was finally investigated, Han Yang felt very sorry and planned to send a member of the ruling committee to apologize and comfort him. But he was firmly rejected by the Red Iron Man.

"Your enthusiasm is unbearable."

The red iron man pointed to his head with an indifferent expression: "I haven't recovered yet, I can't bear it."

This is because I am worried that if I apologize, the red iron man will faint again...

In desperation, Han Yang had to give up this plan and specifically ordered that communication with the Red Iron Man should be simpler and not involve too much red tape.

Unexpectedly, those Hematite people relaxed a lot and integrated into their work faster. (End of chapter)
