Gu Feng had traveled through the Milky Way this time, producing a few teleportation arrays while discovering many materials for crafting high-end formations and elixirs.
For example, he extracted some high-density steel materials that were not native to Earth from a certain planet.
He handed these materials over to the Dragon Nation's steel factories, instructing them to create furnaces according to the patterns he had designed.
The surplus several thousand tons of material could be used for weapon forging reserves and for spacecraft repairs to reduce maintenance costs in the long run.
Besides, Gu Feng also found some crystals in the crusts of certain planets.
These materials might be unfamiliar to people on Earth, but in the memory of that Nascent Soul cultivator, they were spirit stone mines.
With these spirit stones and other materials he brought, Gu Feng could craft many objects.
Such as Sensing Pillars for ordinary people to test their Spirit Roots.
