Chapter 315 Seeing the Mirror Again [Demon]

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 home 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 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 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 a pretty good uranium mine a few years ago? If it is not used to make weapons, but only used to generate electricity, these uranium ores can be used for about 120 years." Professor Sha Mo of the University of Engineering said, "If we use the uranium mines of the Sky City Change from flight mode to floating mode, and the power can be reduced a bit.”

More than 120 years?

It 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, Shamo 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 there are some hydrodynamics-oriented carvings on the walls."

"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, 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."

Idea 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” received a unanimous vote!

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 it can effectively reduce the resistance of water flow.

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.

"Promise 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 Rize 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".

Since Lu Yuan sold them the Pandora crystal, almost every city in Rize has begun to build a "floating fortress" frantically.

After leaving the safe zone, they can piece together a floating city at the fastest speed.

However, in just three months, not even a foundation has been built.

"You... Alas, you should have come out a long time ago."

"Twenty years have been wasted for nothing, and nothing has happened in these twenty years!!"

Because they have been in contact many times, Lu Yuan is no longer polite and begins to sigh, "Now we are all leaving, and you are still in the safe zone, slowly building... Really..."

He was received by the governor of the first branch, Mo Xi.

The lizard man smiled bitterly and said, "You can't say that, Mr. Lu, if a major crisis occurs, you can raise the city and run away. And we are finished, aren't we?"

"What's more, we used that metal communicator... We still have to endure for a few years and observe the outside world."

"It's been so long, and there are no milestones. It doesn't matter if there is a period of time."

Using a communicator is ultimately a huge hidden danger.

The people of Rize really didn't dare to open the safe zone... What if a super civilization came and wiped out humans after it was exposed? Who would they go to for justice?

"That's right..." Lu Yuan nodded, opened the storage space, and took out the last batch of traded materials.

Most of them were extraordinary resources produced by Green Mountain, and a small amount of equipment made by craftsmen.

After a careful inspection, Rize City also moved out various technological materials and asked Lu Yuan to load and unload them 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, won't it remain unchanged?"

Everyone came to the spaceship of the Dalai Empire. It looked like a large oval stone, white jade all over, like an oversized pebble.

According to the current perspective, 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 not been idle. They installed some Pandora crystals on this spacecraft. Otherwise, even the brute force of the Tree of Life would not be able to move a mass of tens of millions of tons.

Lu Yuan did not hesitate: "I will go in first to see how the situation is."

"Thank you for your trouble."

Lu Yuan sighed lightly, a little nervous. This time, even his comrade Lao Mao was not around... There was no way. Lao Mao felt that there was no need to worry about such trivial matters, and there was no need to follow.

It was very busy!

"Swoosh!"

Following past experience, Lu Yuan successfully teleported in.

It was still pitch-black darkness.

Cold and sticky.

It was like being in a cemetery in the dead of night, with an indescribable sense of creepiness.

The power of the [ghost] was still so unfathomable.

[It's you, young man. ]

[How many days have you come back? It seems that you have encountered some difficult problems? ]

This voice sounded from the bottom of my heart, full of a mysterious temptation.

Lu Yuan turned on the flashlight, feeling the cold atmosphere, his blood circulation was speeding up, and his heartbeat was rising - fortunately, it did not exceed expectations.

It has been less than a year in this spaceship, and the [Ghost] still has not broken the seal, which really made him breathe a sigh of relief.

"I just came in to take a look. Do you have anything to say?"

"It's better to say it now, I will leave later." Lu Yuan said indifferently.

His words made the mirror [Demon], who was confident, stunned for a moment.

Even with the intelligence of the [Demon], he couldn't figure out the situation.

[What do you want to know? I know everything. ]

"Myth equipment, do you have it? I want the forging method of myth equipment."

This question is too difficult!

After a long while, the mysterious tone came, [I don't have it. But I know that myth is another realm...]

The mirror [Demon] hesitated to speak, as long as Lu Yuan had a desire, it would always have a chance to take advantage of it.

"So mythology is another realm... Tsk, interesting, then do you know what realm I am in?" Lu Yuan showed his title of "Master Craftsman".

Titles can naturally be shown, that is, they can be discovered through the ability of "identification".
