The Federal Central State Planet Guard Fleet's 042nd Detachment was loading materials for Energy Engines onto a storage ship at a Mineral Star under the guise of a patrol.
At a certain distance from every Mineral Star, there was a spaceship known as a mining star mothership.
This type of ship was mainly used to store collected materials.
Some Mineral Stars merely had the conditions for extraction and lacked purification facilities, so the materials had to be purified inside these ships.
If a Mineral Star had the conditions for purification, then this ship served as a warehouse.
These were all converted super-large Transport Spaceships, with remote personnel inside primarily tasked with monitoring Intelligent Mining Equipment.
However, this Mining Spaceship differed from the others.
Its protection rating was extremely high.
That was because the materials used for Energy Engines were Highly Radioactive Materials.
Their radioactivity was many times greater than that of ordinary materials.
They were not nuclear materials in the traditional sense. Their radioactivity was hundreds of thousands of times greater than that of conventional uranium!
This material was extremely rare. Even the tiniest amount could be lethal.
Therefore, it existed only on High-Density Planets!
To collect it, Mining Companies had to use specialized equipment to mine minerals on such planets.
The minerals were then transported into spaceships for processing, because large equipment could not be deployed on High-Density Planets.
Because of the ultra-high density, the volume of minerals collected each time was very small.
Because the planet's density was high, its gravity was powerful.
Naturally, the energy consumed was greater as well.
That was why this material was so expensive. Whether mining, transporting, or purifying it, the costs were extremely high.
Because this material was heavy and dense, a battleship's cargo hold alone was enough to carry it!
