Zhao Hai led some elders and disciples from the weapon Refinery Hall and the Dharma array Hall to the floating city. This time, Zhao Hai was going to take them into the space and place the Dharma artifact in it for testing.
The reason he brought these people here was to let them know about the existence of this space. Zhao Hai knew very well that no machine parts were indestructible. In other words, the large spiritual artifact might be damaged in the future even if it was stored in the space. If he didn't tell them about this place now, what would happen to the floating city if the parts were damaged and he ascended again? Would he fall from the sky? Obviously, that would not work. Hence, Zhao Hai wanted to tell these people about this place. In the future, the job of maintaining this place would be left to them.
