Seeing that everyone's morale was high, some of Lu Yuan was also infected.
He was looking forward to the day when he would return to his hometown in glory... Well, it was unimaginable what kind of sensation that day would cause.
At this moment, Comrade Lu Ying from the Investigation Department raised his hand and said: "The direction of the mother civilization is to the northeast. According to our investigation, there is a vast sea there. Our city in the sky cannot stop at any time.
Take a break, this is a huge challenge for the energy system."
Yes, there is a sea on that side, and humans have already investigated it clearly.
Nowadays, if you want to return to your mother civilization, you must cross the sea.
But given the huge size of Pangea, humans still don't know how big the ocean is.
Therefore, sufficient energy must be prepared, otherwise if the energy is lost halfway, the sky and the earth will become inoperable.
Energy is divided into two types, physical energy and spiritual energy.
"Most of the current physical energy consists of nuclear power units."
"Didn't we dig up a pretty good uranium mine a few years ago? If it were not used to make weapons, but only used to generate electricity, these uranium mines would be enough for about 120 years." Professor Sha Mo from the University of Engineering said, "If we use the uranium mines from City in the Sky
Change flight mode to floating mode, and the power can be reduced a bit."
More than 120 years?
There seems to be quite a lot, but not enough to fill a sense of security.
Fear of insufficient energy!
As if seeing everyone's doubts, Sha Mo explained: "The flight mode uses Pandora crystals to completely offset the gravity of the rock, relying on the buoyancy of the air to float the city at an altitude of 30,000 meters."
"The floating mode is the same. It just uses the buoyancy of water to float the city on the sea. It does not need to completely offset the city's gravity, so the energy required will be smaller."
"When the Green People designed the city, they had already taken this aspect into consideration. Therefore, the thickness of the city's foundation is particularly large, and the walls also have some carvings in the direction of fluid mechanics."
"What are the benefits of floating mode?" Lu Yuan asked.
"On the one hand, it is to save energy. As we all know, the buoyancy of water is 800 times that of air. Our power grid does not need to be fully powered, just about a quarter of the power..."
"Moreover, the floating mode makes it easier for us to harvest resources on the seabed. The ocean is a huge treasure, richer than land, and even a green civilization is unwilling to miss the opportunity to explore ocean treasures."
Sand Desert talked eloquently: "The last benefit is to avoid enemies in the sky."
"The city in the sky is not completely without enemies. Facing some flying phenomena and huge storms, it is better to stay in the ocean."
"If we encounter a particularly huge underwater monster, we can raise the city again."
"Shouldn't they be captured to make elixirs?" Lao Mao, a comrade of the Greedy Demon God, couldn't help but say.
Then everyone laughed.
The increase in strength has indeed given everyone more confidence.
Shamo cleared his throat: "Also, we have two sets of energy systems. The first set is physical energy, which is the energy supply under normal conditions. The nuclear power reserve is 120 years, and the parts can be produced through the universal factory, so there is no need to worry.
.”
"But if a war breaks out, the power grid may be destroyed. In order to prevent the city from sinking into the water, we have also prepared distributed spiritual energy, that is, there is a small amount of spiritual crystals in the Pandora crystal network to supply energy."
"One unit of aura can probably make the city fly for 4 days and float for 16 days."
"We have prepared about 20 Lingyun, which can provide 80 days of flight time, or 320 days of floating time on the water. If there is a serious crisis, this emergency time is enough."
Ideal Energy, because it is distributed, is like batteries.
Even if there are explosions in certain places, the rest of the Pandora crystals will still work normally.
Lu Yuan nodded: "Your arrangement is very good, as long as it doesn't sink to the bottom of the sea easily."
All in all, human ambitions, far from being extinguished, are burning like a flame.
Sky City’s “Floating Across the Sea” was unanimously approved!
The glyph working group led by Guo Weiqiang, with a total of more than 150 regular employees, painted and repaired the "drifting glyph" on the wall.
This combination of glyphs was learned from the Immortal Giant Turtle, and can effectively reduce water flow resistance.
If the resistance of the ocean current on one side is small and the resistance of the ocean current on the other side is large, then a natural driving force will be generated, allowing the entire city to move forward slowly.
"Guaranteed to finish it within three months!!" Guo Weiqiang issued a military order, "Commander Lu, you go to the safe zone for a day, and it will be completed when you come out! Soon!"
Lu Yuan rolled his eyes, Lao Guo, I always feel like you are teasing me.
After the meeting, he couldn't help but sigh in his heart, human beings have indeed become a lot stronger. In the past, he was the only one who could carve words, and many tasks simply made his scalp numb.
But now, there are more than 150 people who can "drift glyphs".
…
Next, Lu Yuan was not idle. He took the Tree of Life and teleported into the safe zone of Lize Civilization.
Compared with the vicissitudes of human civilization in the 18th century, the changes in the safe zone are very small.
20 years to the outside world, less than three months to the inside...
Really...too short.
The first branch of the Lize civilization is building a foundation for the "Floating Fortress".
Ever since Lu Yuan sold them the Pandora Crystal, almost every city in Rize began to frantically build "Floating Fortresses".
After leaving the safe zone, they can piece together a floating city as quickly as possible.
However, in just three months, not even a single foundation was completed.
"You...well, you should have come out a long time ago."
"Twenty years were wasted. Nothing happened in these twenty years!!"
Because they had been there many times, Lu Yuan was no longer polite and began to sigh, "Now that we are leaving, you are still inside the safe zone, slowly building... It's really..."
Receiving him was the governor of the first branch, Moshe.
The lizard man smiled bitterly and said: "You can't say that, Mr. Lu, if a big crisis occurs, you can raise the city and run away. But wouldn't we be finished?"
"What's more, even if we use that metal contact... we still have to wait a few years to observe the outside world."
"It's been so long, and there's no milestone. It's about that long."
After all, using a liaison device is a huge hidden danger.
The people of Rize really don't dare to open the safe zone... If after being exposed, some super civilization comes over and wipes out human beings as well, who will they ask to reason with then?
"Yes..." Lu Yuan nodded, opened the storage space, and took out the last batch of transaction materials.
Most of them are extraordinary resources produced by some green mountains, and there are also a few equipments made by craftsmen.
After careful inspection, Lize City also moved out various technological supplies and prepared them for Lu Yuan to load and unload as soon as possible.
"Our physical technology tree is exactly the same as yours." Lu Yuan joked, "I hope there will be some differences in a few hundred years."
"Hey, it's a good thing to have differences. If there are no differences, wouldn't it be the same?"
Everyone came to the Dinalai Empire's spaceship. It looked like a large oval stone, white jade in color, like an oversized pebble.
According to current perspectives, the other technologies of this spaceship are not very good.
But space technology is indeed far beyond the scope of human cognition.
In the past few months, the people of Rize have been busy installing some Pandora crystals on the spacecraft. Otherwise, even with the brute force of the Tree of Life, it would be impossible to move the mass of tens of millions of tons.
Lu Yuan didn't hesitate: "I'll go in first and see how the situation is nearby."
"Sorry to trouble you."
Lu Yuan breathed a sigh of relief, feeling a little nervous. Even his comrade Lao Mao was not around this time... No way, Lao Mao felt that there was no need to worry about such nonsense anymore, and there was no need to follow him.
It's very busy!
"Whoosh!"
Following his past experience, Lu Yuan successfully teleported in.
It's still so dark that you can't even see your fingers.
Cold and sticky.
It was like being in a cemetery in the dead of night, with an indescribable feeling of creepiness.
The power of [Ghost] is still so unfathomable.
【It's you, young man.】
[How many days have it been since you came back? It seems that you have encountered some difficult problems? 】
This voice sounded from the bottom of my heart, filled with a mysterious allure.
Lu Yuan turned on the flashlight and felt the cold atmosphere. His blood circulation was accelerating and his heartbeat was rising - fortunately, it did not exceed expectations.
The time in this spaceship was less than a year, and the [Ghost] still hadn't broken through the seal, which really made him breathe a long sigh of relief.
"I just came in to take a look. What do you want to say?"
"It's best to say it now, I will leave later." Lu Yuan said coldly.
What he said made the mirror [Devil], who was already holding his chest, stunned for a moment.
Even with [Devil's] intelligence, he can't figure out the situation.
【What do you want to know? I know everything.】
"Mythical equipment, do you have it? I want the forging method of mythical equipment."
This question is too difficult!
After a long while, the mysterious tone came, "I don't have it. But I know that mythology is another realm..."
The Mirror [Demon] hesitated to speak. As long as Lu Yuan desires something, it will always have the opportunity to take advantage of it.
"It turns out that mythology is another realm... Tsk, interesting, then do you know what realm I am in?" Lu Yuan showed off his title of "Master Craftsman".
Titles can naturally be revealed, that is, discovered through the ability of "appraisal".
It is impossible for Lu Yuan to show the demon hunter or monster hunter. It is his personal secret. Only the "master craftsman" thing has value if it is displayed!
Lu Yuan doesn't know if the mirror [Demon] has the ability to identify...
But what’s wrong with him just showing off?
…
(PS: Ask for a monthly ticket!)
