When seeing these little dragons, the giant tortoise man was surprised, and there was no lion's big talk. He sold the quota only at a regular price of 2 million per place.

Nothing is particularly expensive, nor is it cheaper.

Lu Yiming reminded calmly: "Although the other party is an old turtle, it may be your future teacher. Please give me the key points. Don't think about biting people as soon as you meet, and don't make strange sounds. Learn more skills, it's always good."

"You are already a big dragon. You should go to school and learn more skills. Now you can't even speak, so you can't continue like this!"

These dragons have grown to 80 kilograms, and the weight of an adult woman is getting bigger every day.

One of the dragons screamed "awoo" and wanted to lie on the top of Lu Yiming's head and act coquettishly. But he found that he was too big. Lu Yiming's head was only so big that he couldn't even lie down.

It was wondering why this big brother who usually feeds them monster meat is so small? Then he started to scream.

Something is wrong. Brother, why don’t you eat? How can you grow up if you don’t eat!

Lu Yiming was holding this dragon that insisted on acting cute, and he couldn't help laughing and crying.

"Hey, I'm still like a child."

He was very suspicious that these stupid dragons could only learn some air!

More than one million yuan of money was spent in vain again.

However, the little golden dragon was very cautious and swam in the air, with two beards floating one after another. Its IQ was far beyond the stupid dragon, and it was the only hope among the nine brothers.

"The place of Lord Xuanwu is ahead." The old master of the Giant Turtle Kingdom led the way forward, quietly looking at the dragons.

Giant Turtle people have always been very awe of supernatural life.

They also have dragon culture and know that these guys are the legendary dragons, just like the dragon in the Great Jin Kingdom.

Unexpectedly, the capital of the Sea of ​​Clouds still has such a foundation, which makes these giant tortoise people feel very strange.

"What's the relationship between the Great Jin State and the Capital of the Sea of ​​Clouds?" He started to speculate in his heart.

With a slight "creak", the door was pushed open. In Xuanwu's room, there were about twenty practitioners sitting, most of them were children, and several older middle-aged people.

Xuanwu was thinking about a math book. Because he was guided by mathematicians some time ago, he felt that he had made great progress and could do it again on certain problems.

The old master stepped forward and said a few words to Xuanwu.

Xuanwu raised his head and saw the little golden dragon and the little dragons. He also widened his eyes and looked at them for a while.

These dragons have something to do with the big black dragon in the Great Jin State, but it seems that they have nothing to do with it...

After reading for a long time, I couldn't understand it.

These little dragons, who are usually very noisy, have become honest like never before. After all, the white turtle in front of them has lived for a long time. It is absolutely right to respect the elderly. These little dragons were raised by humans and instilled with human values ​​in their heads.

Although they are naughty, they also know politeness.

"I'll trouble you with the teachings of these little dragons." Lu Yiming saw them so honestly and smiled: "They will stay here to study for a while during the day, and they have to go back to bed at night. It's better to learn more skills and save you from doing nothing all day long."

"As special species, these guys will have a dedicated person to accompany you when learning. Please forgive me for this."

The little golden dragon shook his tail a few times, as if he was trying to please this super-age teacher.

The white turtle opened its mouth and seemed to laugh. It was originally a very Buddha-like creature, but in fact it didn't matter who was his own student. It also had no idea of ​​cherishing itself, and the knowledge in its mind was no problem no matter who learned it.

In addition, it has been asking about mathematical problems these days, and has gone further and further on the road to pursuing truth, and has figured out many problems that have not been understood before.

If it wasn't for the fact that it had a little affection for the Giant Turtle Kingdom, it would have wanted to run to the capital of the Sea of ​​Clouds and see how many books there are in the real Central Library!

Where will it make a fuss about these small issues?

...

So, time passed day by day...

All development is slowly getting on track, and the infrastructure construction of the capital of the Sea of ​​Clouds and surrounding islands is still underway.

All surrounding countries are also quite stable. Except for an internal riot broke out in the Greater Radisson, other countries are trying to develop their own advantageous industries.

In a blink of an eye, it was another six months before the arrival of the giant tortoise civilization. The giant tortoise civilization is the last civilization before the arrival of night. After that, Yanghe was in a state of monsters and monsters running around.

Lu Yiming found that he was too old and followed Xuanwu and could not learn too much, so he had to go back first.

He has a lot of things to be busy with...

The first and most important thing is the manufacturing of giant spacecraft in the Yin World Corridor!

Whether it is looking for compatriots or capturing the ideal world next door, a giant spacecraft that can shuttle through the corridor of the Yin world is a must. Without a giant spacecraft, it is too difficult to shuttle through the body.

It was also from Xuanwu that the whereabouts of his compatriots were obtained. The manufacturing of the giant spacecraft entered the fast lane. The capital of the Sea of ​​Clouds concentrated almost all its production capacity for the manufacturing of this spacecraft.

But this giant spacecraft has many difficulties for the current capital of the Sea of ​​Clouds.

The first is the problem of the ecosystem. There is no air in the Yin World Corridor. The spacecraft must form an ecosystem and achieve internal balance. This ecosystem does not need to be permanently balanced like a spacecraft, but it must be maintained for more than one year.

This puts higher requirements on the space volume inside the spacecraft.

Just like a body of water, the larger the body of water, the less likely it is to be polluted, and the stronger the internal self-regulation ability. The larger the internal space, the simpler the construction of the ecosystem will be.

The internal space is too small, and a little pollution will destroy the balance.

Moreover, it is large and can carry more people to survive on it. Even if hibernation equipment is placed, there must be enough internal space.

"So, according to calculations, the internal space area of ​​the giant spacecraft must be at least 2 million square meters, which is 2 square kilometers, with a capacity of 3 cubic kilometers. The mass of the air alone will reach 3.9 million tons. This number is not small, equivalent to one-tenth of the Yunhai Sanctuary. Among the mass of the spacecraft, internal air accounts for the vast majority."

"After finding our compatriots, they will be brought back through hibernation. They can carry hibernation of 100,000 ordinary humans at one time."

"Eventing in the Yin World Corridor requires high-dimensional glasses or faceless women's red clothes, so you need to prepare the corresponding equipment."

This internal development meeting determined the major size of the spacecraft and the specific square array.

The production capacity of the universal factory is fully activated, and all the hibernation warehouses and corresponding auxiliary equipment are completed in less than a month.

The second difficulty is the material problem. In order to prevent all kinds of messy idealistic rules from interfering with physical operation, the main material of the spacecraft must be composed of biological materials, otherwise unknown risks will arise. The performance of conventional physical materials is too susceptible to the destruction of idealistic rules, but biological materials do not allow them.

Most superpowers are actually quite difficult to directly change the performance of biological materials.

In the past, this problem was a huge problem. Although universal factories have huge productivity, they cannot produce any biological materials.

Although Jin Baobao’s silk spinning is good, it is not easy to process silk into an airtight hull?

But now, after receiving so much civilization, the almost perfect hull material has finally appeared!

There are two different solutions in total, one is the world tree from the Yuzhu civilization, and the second is the tortoise shell of the giant tortoise civilization!

These materials are all sold for islands and are already materials from the capital of the Sea of ​​Clouds. If it weren't for this reason, what would people want these ancient civilizations to do?

After careful selection, people still chose the "turtle shell" of the tree turtle as the main raw material for the first giant spacecraft.

Its airtightness is very good, the turtle shell is airtight, and there are gaps in the six places, namely the head, tail, and limbs. It is relatively simple to completely enclose the internal space; in terms of this, the airtightness of the World Tree seems a little worse. Due to the original internal construction of the Yuzhu people, it was dug into the shape of a canoe, and it was more difficult to transform it into a spacecraft.

In order to improve the performance of the giant spacecraft, people specially installed it with four anti-gravity engines, which were removed from the anti-gravity fighter.

With these things, you can fly easily.

In addition, there are 16 propeller engines and 16 jet engines, as the main power. The Yin World Corridor is not a vacuum universe in the complete sense. It has a small amount of "ideal gases". These unknown products still retain the physical properties of the gas, so the propeller engine is still effective.

As for the energy system, six cold nuclear fusion energy devices are used.

These energy devices were disassembled from excavators from underground ruins and installed on the spacecraft.

Two nuclear power units, namely the most conventional nuclear fission energy device. Nuclear fission energy is the most conventional energy device for human beings. If Xia Civilization’s cold nuclear fusion device is broken, it can still be used for backup use with nuclear power.

With this formal insurance package, energy should not be a problem.

In addition, six high-energy psionic batteries were installed. These psionic batteries were made of crystals from the body of the evil god and could stimulate 500,000 units of shields.
