Some of the ships in Dolap's fleet still use nuclear reactors to provide energy, so they need to consume hydrogen as a raw material for nuclear fusion.

As a huge gas planet, Planet Zeli C has a huge reserve of hydrogen. Some of this hydrogen is free outside the atmosphere and floats in the universe in the form of particles.

The fleet only needs to stay in the planet's low-Earth orbit and deploy a collection force field, and these free hydrogen ions will be absorbed into the spacecraft reactor.

This method is called soft refueling, and there is naturally a corresponding mode called hard refueling.

Unlike the former which collects scattered hydrogen particles through force fields, the principle of hard refueling is similar to the atmospheric condenser that Bai Yi used in the Aiguille galaxy.

This method requires the spacecraft to get as close to the planet's atmosphere as possible, and through a hose made of nanomaterials, naturally fall into the atmosphere of the gaseous planet under the action of gravity.

Then the atmospheric components are directly absorbed through the pipeline, and the required parts are retained after filtering.

This method of supply is extremely efficient, but it is also very dangerous, and the hundreds of kilometers of hoses and supporting equipment are also a considerable expense.

So it is not usually used.

Not long after Dolap's fleet left, a giant elephant entered the galaxy.

This is not a spaceship to pick up refugees.

Its function is to blow up the entire planet Zeli B.

Due to the massive deployment of military fleets, the Stargate route is already extremely congested. The remaining transport capacity must be allocated first to the member states of the Galactic Alliance to transport the population within their jurisdictions.

There is no time to play house games with these natives. Such uncooperative wild civilizations must be eliminated with tough measures.
