As for Kerr's attack method, he could barely understand 40% of it.
That remote space transmission gate is the technology of the Star System Federation, which can teleport non-living objects over long distances, but cannot teleport living beings. The limit of civilian remote space transmission gates is a width of 15 meters.
To break through this 15-meter limit, military-grade remote spatial portal rights are required.
This is also something he could achieve, so there is nothing to be surprised about.
However, it will take a large amount of Star Coins to open such a large remote space transmission gate. Of course, it would not be as much as he offered, but it would leave only a few left.
Moreover, the exaggerated cannon and the continuous firing of cannon shells probably consume astronomical amounts of energy.
Roughly estimated, the cost for Carl Jacob Company during this mission would not be compensated by 300 million Star Coins.
Is it a loss-making business?
