Dyson Cloud

When the Blacklight, the first extraterrestrial emigrant spacecraft in human history, entered the subspace, it disappeared from this universe and no signal would be transmitted back. Chen Chen would not know whether it succeeded, became trapped in the subspace or had been annihilated at once.

Before it returned to the solar system, no one would know anything about the Blacklight.

On this side of reality, Chen Chen's experiments on subspace navigation were still going on, and he did not slack off just because the Blacklight had gone on a mission.

At the same time, with the birth of the subspace engine, Chen Chen decided on his own to build ten large transport ships comparable in size to aircraft carriers. These ships could carry over a thousand small unmanned mining ships that were less than ten meters in length.
