The pressure test was not the most difficult step in the quantum teleportation channel, but it was the most terrifying step. This was because at the end of the pressure test, the Planetary realm powerhouses of the Spiritual Race would definitely be used for the pressure test.
After all, after the multi-person quantum teleportation channel was built, the people who used it the most were the experts of the Spiritual Race. Therefore, be it objects, ordinary people, or captives, they had to be tested by a Planetary realm powerhouse of the Spiritual Race.
This was also because the higher-ups of the Spiritual Race were responsible for their lives. Even if a Nine Satellites Planetary realm powerhouse encountered an accident, they would not die. Under most circumstances, they would have the ability to deal with it.
