Ever since he decided to use the system to his advantage, Tang Yin has realized how amazing it can be and that sometimes it will give him surprises when he least expects it.
In this case, he originally thought that the mission would give him some high-level external spiritual weapon since that's the kind of reward it most often gives, but that it would give him a Hall like this to make arrays was the last thing he expected.
Even in his world, a place like this does not exist outside of the creations of the gods of the past.
It is not impossible to create halls or powers that go against the laws of nature or go against the laws of space, but...
To create something that goes against the laws of time is absolutely impossible for humans to do.
Time is the only one in which they cannot interfere in their world, and there are only a few Pocket Worlds that were left by the gods of the past that can go against real-time.
