On February 5, 2013, China Time, in the East Eighth District of Earth, Yang Xi handed over a list to Tao Jiu, asking her to prepare to notify each one, count the receipt, and arrange the cabin back to Earth.

Tao Jiu was excited to see that she and Duda were on the list, and finally could enjoy a love a true earthling. She seemed to have seen a cinema, singing hall, bar, commercial street...

Duda was still very excited when he received the notice, but what he thought of was a gathering of friends and his parents were filial to him... In comparison, Duda has matured a lot because of two years of life.

The scientists who received the notice were even more excited. After half a month of day and night research, they finally successfully ignited the fire and started the reactor that was almost extinguished again. Two large spacecraft regained energy and successfully tested it. This product of the second-level universe civilization is simply approachable compared to the lunar civilization. A group of scientists and engineers who were hit by the lunar people and were on the verge of collapse have regained the confidence of the human elite.

"I want to go back to Earth with you." Zheng Ran didn't take the initiative to look for Duda for a long time.

Since last time he forced Duda on the hospital bed to take a risk, Tao Jiu has become less and less popular with the chief scientist. Zheng Ran himself was a little self-conscious, so he gradually became alienated from Duda. Because Duda got out of the company, he learned the basic common sense of military life, and had a dinner with his newly recognized comrades... and he didn't even bother to find Zheng Ran.

And, why do you look for the third-ranked science madman?

Crazy No. 1 is suspected of intentional murder, human experiments, and is still under residential surveillance!

Madman II has never had the chance to meet. He is the chief scientist in Russia. It is said that he is now studying the remains of a lunar human, and he doesn't even leave the laboratory door.

Think about it with your knees, Madman No. 3 is not a good person either.

"Isn't this a list planned by the military headquarters? Why are you looking for me?" Duda said in confusion.

"I don't want to ride the Han level back to Earth." Zheng Ran said bluntly, "I'm going to waste my time. I want to ride the Tang level."

The Han and the Tang dynasty.

The unknown alien spacecraft was named Dahan class, among which Dahan class 001 was named: Xiao He. Another one was called Han Signal.

It is said that this is the inspiration that Commander Li Weijun got when watching the Peking Opera "Xiao He Chasing Han Xin under the Moon".

The moon aircraft was also designated as the Tang Dynasty. What made Du Da feel that the world collapsed was that the military officials named his beloved landline: Princess Pingyang - the Tang Dynasty princess who founded the Detachment of Women and stationed at Niangzi Pass without asking for his consent.

In addition, Deputy Commander Yang Xi said: In the future, all lunar aircraft will be named after the title of Princess of the Tang Dynasty. Who made them all round and cute?

Of course, to the outside world, the explanations of the military’s people was: the Han and Tang dynasties were the two most glorious dynasties in Chinese history.

Duda was a little awkward about the two names, but those in the military unanimously approved it, especially Tao Jiu's factor, so the protest was invalid.

The Dahan class starts from the moon, and even the shortest voyage takes four hours. Moreover, the Dahan class cannot land directly - no suitable landing site is found - can only float at high altitudes. Where can all passengers transfer to planetary transportation, such as aircraft and airships, it is not recommended to use parachutes.

Finally, because of Duda's outstanding merits and the force of Princess Pingyang, the Moon Club passed a resolution: China has the highest priority of two of the four large spacecrafts - in fact, it is ownership, just legal wording, which is understood by all mankind.

All attachments and equipment in the spacecraft have the right to allocate and use.

The Chinese government welcomes any country to borrow these two spacecraft, but it is appropriate to charge fees. For example, now, if soldiers from other countries and scientists want to return to Earth, they must buy tickets.

Not only Zheng Ran, but also Tao Jiu and Su Luo, were going to ride Princess Pingyang.

The diameter of Princess Pingyang's cabin is only 2.6 meters, and three people squeezed behind Duda like they were squeezing a bus.

This is why Tao Jiu was extremely unhappy.

But Princess Pingyang is not Duda's private property after all, so Duda can only accept it. Considering that it only takes thirty minutes to get home, the two ladies felt that they could bear it and pass it.

Therefore, the military can sell three more boat tickets to other countries in need. Although the Dahan-class space is spacious, the seats are too limited.

Considering that the cost of the Earth-Moon shuttle is higher, governments of various countries are still very satisfied with the price of the Chinese government's ship tickets.

As the first earth-moon trip, the two Dahan class ships had to carry 40,000 passengers, a large number of experimental equipment and specimens, and entered the atmosphere through a four-hour sailing. They placed two batches of passengers and cargo in the Americas and Europe respectively, and then placed the last passengers and cargo in the unmanned land in western China.

Duda's mission is to return to Hangar 1, the first air hangar discovered, after the formation sets, pick up three passengers, and then catch up with the formation, opening a safe gap for the formation to ensure that space garbage will not damage the two transport ships. Given that the two spacecraft are likely to be assembled at the space station, neither of them is very optimistic in terms of armor strength and high temperature and friction resistance.

The data obtained show that the tolerance of Earth and Moon shuttles is slightly stronger than that of them.

Duda did a thorough job, and all the fragments visible to the naked eye were blown into pieces and returned to the universe in the form of elements. Although he did not know the source of the energy of the moon, according to scientists, the moon has existed for 4.6 billion years. Since it has not fallen after so long, the energy of a mere aircraft is definitely no problem, so there is no need to save anything.

"Are you going back to Earth to celebrate the New Year?" Duda broke the silence and asked Zheng Ran.

"Speechs from the Chinese Academy of Sciences and several universities." Zheng Ran said with a little disgust, "Also, select a few assistants."

Zheng Ran's temper is closely related to sleep time. Once his assistants find that he has not slept for more than 24 hours, they will turn to others' disciples and even disappear. This makes Zheng Ran hate it. Every year, he will return to China to select some young people who are not well-versed in the world as assistants. However, the final result... it can only be said that reincarnation continues.

After Duda asked this question, he couldn't think of other topics, so he sent three passengers home first, and then returned to space to wait for the Han-level formation. This time he perfectly mastered the trick of slow flight, and landed in the suburbs of the capital without causing damage to people's property.

The Han-level successfully passed the low-Earth orbit and entered the atmosphere. Although the data are worrying, the alien's cosmic technology is indeed two levels higher than that of the Earthlings. It has good anti-gravity deceleration and liquid nitrogen condensation technology in terms of crossing the atmosphere, and it does not even give passengers the chance to complain about bumps.

After entering the atmosphere, the Han-level was escorted by the air power of the three powerful countries on Earth, and Duda successfully completed the mission.

The military department agreed very humanely to Duda drive the Pingyang Princess home for the New Year. His rank awarding ceremony was scheduled for the third day of the Lunar New Year, and it has been confirmed that it was an exception to be promoted from a second lieutenant to captain. However, the high-level awarding of ranks that had been originally agreed to have become a luxury, because all the heads and minds of governments on earth are busy with one thing:

The Great Moon Immigration!

According to scientists' estimates, if humans on Earth only use the residences left by the lunar people, the most conservative immigrant population is 8 million. If there are enough building materials and the interior of the lunar people is built according to the habits of the lunar people, it can accommodate more than 30 million people, forming a huge lunar city.

Of course, an air city is not what politicians care about. What they care about is the resources on the moon.

The moon has extremely rich mineral resources.

Take iron as an example. Sand soil of only 5 cm thick on the surface of the moon contains hundreds of millions of tons of iron, while the entire moon surface has an average of 10 meters thick on the surface. The iron on the moon is mainly iron oxide, which is enough to separate oxygen and iron, which is easy to exploit and smel. In addition, there are rich mineral resources such as chromium, nickel, sodium, magnesium, silicon, copper, rare earths, etc.

And there is the most sensitive energy for humans.

After mankind obtains a first-level cosmic civilization, nuclear fusion will inevitably become the mainstream of future energy. Although the nuclear fusion fuel in seawater can be used by mankind for tens of millions of years, the more efficient, clean and easy-to-mix fuel is actually helium 3 in the soil of the moon.

Now the Dahan class uses the isotopes of deuterium (D) and tritium (T) fusion of the isotopes of hydrogen, which are hydrogen-based. This hydrogen reaction will produce a large number of neutrons, which is very dangerous to organisms.

In the scientists' timetable, the next generation of fuel should be the deuterium helium reaction, and produces very few neutrons. If nuclear power plants that use deuterium and tritium fusion must be far away from cities, then hydrogen and helium nuclear power plants can be completely built in the city center.

The final fusion reaction is a helium nuclear fusion using helium 3 and helium 3. There is no neutron production in the reaction, safe and pollution-free, and is an easy-to-control nuclear fusion.

The nuclear fusion reactor on the Dahan class uses helium nuclear fusion to power ships, but because the Earthlings do not have enough Helium 3 as fuel - there are only about 500 kilograms in the world.

But Helium 3 is not rare on the moon...

The content of helium 3 in the lunar soil exceeds one million tons!

For every ton of helium 3 extracted from the lunar soil, 6300 tons of hydrogen, 70 tons of nitrogen and 1600 tons of carbon can be obtained...

If humans would fight for oil in the Earth era, then in the next war, humans would inevitably fight to seize Helium 3!
Chapter completed!
