In the prolonged years of work and practice, scientists are able to accumulate a wealth of effective data, and the mysteries of space technology are close at hand!
After the tunnel between the Ruins of Buzhou and the Iron Key Race was connected, a large number of scientists moved there to contact and study the remnants of the Fifth-level Civilization.
Even if they cannot understand the specific principles, seeing and observing are beneficial.
A very important aspect of scientific research is to confirm that "this path indeed exists."
As long as the existence of the path can be confirmed, subsequent development will be much smoother.
For example, Earth's first atomic bomb consumed GDP equivalent to 1,530 tons of gold, an astronomical figure!
However, subsequent national developments of atomic bombs became much simpler. Eventually, even the specific principles were publicly available online, and making an atomic bomb became possible with enough centrifuges.
