The altitude can reach 30,000 meters.

I don’t know if I can break through the sky.

Anyway, that's how it's introduced. If ten satellites are launched into space, they can cover an area of ​​tens of millions of miles and transmit the images they see clearly to the ground.

Their functions are far more than that, encompassing the functions of satellites with different purposes on Earth.

For example, communications...navigation...or military purposes.

Very powerful black technology.

Dozens of transmission towers were built at one time, and all operating systems were installed indoors.

Chai Su was dazzled by the rows of buttons.

3D printers were also built.

The sky signal machine produced is flat in shape, one meter long and wide, and dark gray in color. In short, it has some sci-fi elements.

The surface material has strong pressure resistance and is extremely powerful.

It can stay in the air for a year, after which it needs to be recovered.

…

After becoming familiar with the operation, they lifted these sky signal machines onto the transmission tower.

"emission!"

The transmitting tower is the primary power, pushing the signal machine to an altitude of one thousand meters. During this period, the power of the signal machine will be generated and rise sharply to the critical point.

The three layers of power pushed the signal machine to an altitude of 30,000 meters.

"call……"

Chai Su breathed a long sigh of relief.

Half an hour later.

The image finally appeared on the console screen, which had been black until then.

That was the image transmitted by one of the signal transmitters.

There was a vast expanse of white all around, which should be the lingering clouds.

Zoom in.

They saw the complete terrain of Huacang.
