The last piece of the puzzle in Ouranos, Helltown.

Now it was as if the flames were burning, and the flames were rising in the sky, and the flames seemed to have become the symbol of this place.

The city is still the same city, but it has a different taste, the flame is the most beautiful color, constantly burning in the city, just from the bridge, this whole look very ordinary suspension bridge does not give people any impression, but just come in, I saw two burning dragons.

That's right, it looks like a constantly beating fire dragon, these two dragons hover on both sides, wrapped around two pillars, looking like two Huabiao, very spectacular.

The fire dragon is a real fire dragon, and the flames rising inside are constantly burning, which is a flame from the depths of the volcano, which is somewhat different from what you see every day, because it is not so bright, and the color of the flame tends to be transparent, more like white gold.

The temperature of the flame is obviously very high. It takes about 1400 degrees.

Such a high temperature is enough for smelting, and here it is just an ornament.

The flames inside it were completely blocked by transparent glass, and the flames could not burn the glass, and the temperature could not be felt outside, only the two fire dragons could be seen constantly rising.

The car slowed down slightly as it approached the two totem poles, allowing them to take a closer look at the dragon inside.

"This is the temperature of the flames in the center of the earth, and the temperature in Hell City is more than a thousand degrees, which is very hot. Si Fan's voice rang out in their car.

At this time, they realized that this was Si Fan's territory, don't look at him walking all the way, but people have long known about this place.

Moving on, the city can gradually be seen, there are no particularly tall high-rise buildings here, which is a little different from what is told in future science fiction, most of them are about six or seven dark red buildings, and some look like ancient witches' castles.

Si Fan's car walked in such a city, but it was a little out of place, and there were more bluestone slabs on the road.

"The city is not very big, more often it relies on walking, there are not many modern facilities, and this time we can come in and drive is an extra special approval. Si Fan introduced to everyone.

Gradually, people will be able to see the city, there are flames everywhere, and the lights on the side of the road do not shine during the day, but they are still on.

Unlike other cities, where the lights are turned on at night, the lights in Hell City are only closed during the day.

Because, the lighting of the whole city is the use of heat from the center of the earth.

"It's such a crazy city. "Entering the city, you can gradually see a daunting place, every inch of land has a little bit of it depends on the power of this huge magma in the core.

The core of the city is the huge pipes, the power of the volcano is violent, but in this city they are docile like cats, and they can be found everywhere.

Cars drive on the road, people look at the scenery outside, in this city, there are very few places to live, more are huge factories, red walls, white factories, standing on both sides of the road, the living area can also be seen, in a piece of commercial street, interspersed with residences.

Their car went straight to the industrial area.

The industrial power of the city has reached a suffocating level, and when you see the factory, the first thing you feel is that it is high-end.

The second feeling is despair.

Many companies are desperate to face a huge manufacturing machine instead of an ordinary factory.

The convoy stopped in front of one of the biggest red tall buildings, which was probably the only tall building, more than a dozen stories high, looking like a huge mille-feuille, stacked on top of each other, each by one small windows are not the kind of floor-to-ceiling windows that people like in life, but there is glass everywhere, and the view is very good.

The car stopped, the people got down first, Si Fan opened the car door, and stood outside the building looking at the factory.

"This is the world's first low-gravity dust-free and efficient workshop. Si Fan introduced to the people present.

After they got out of the car, they had carefully observed the factory and found nothing special, but when Si Fan introduced them, they were shocked, really shocked.

"Are you sure that weak gravity can be reached here?" asked Duke Lawrence, who was different from others, who knew more and had his own mechanical company.

Specialized in the elite is ultra-efficient electronic chips.

The production is high-end products, which are generally used in large-scale equipment or commercial equipment.

And one of the key points involved is:

During the manufacturing process, the earth has a gravitational pull, and this gravitational force itself has an effect on the workpiece.

If you are in a gravity-free environment, in fact, a lot of accuracy will be a killer.

"The first company to move in here was Dade Metals Rare Metals, whose main product will be a completely homogeneous alloy. Si Fan introduced.

The crowd erupted in admiration.

One wants to make alloys that are perfectly homogeneous, but under gravity, it is impossible to mix the different elements very evenly.

Scientists have long created highly homogeneous aluminum-zinc alloys in the gravity-free conditions of spaceships, which are light and strong, making them ideal materials for aircraft and rockets.

But it's just the ideal material. They cannot be mass-produced in a cosmic environment.

And now, this condition has been removed.

The so-called weak gravity should still have gravity, but the lift must also be very obvious.

"If you are interested and can invest, we welcome the world's top enterprises and national military enterprises to settle in, where you can produce large-size, defect-free monocrystals. “

"It is also possible to make very high purity materials; Separation of substances that are difficult to separate, and can be formed in a perfect circle. ”

"You can even open a hospital that specializes in treating incurable diseases. ”

Si Fan's introduction is simply undisciplined and bottomless, and everyone is welcome to invest, but only the top companies.

To put it bluntly, the rental price of this factory is probably sky-high, and in addition, there can be a lot of disgusting requirements.

Even so, many people are starting to get ready to move.

"What level can your so-called weak gravity be reduced to, and what effect can it achieve? "Finally someone asked.

This is the main problem.

Si Fan didn't think about it.

"By weak gravity, I think it's almost the same as gravity in a universe detached from Earth. No amount of gravity can be removed. ”
