Exploring the cave dwelling was of course not a decision solely made by Zhou Mingde.
Faced with Shen Borong's inquiry, he merely calmly listed a few opinions.
After some discussion, the three of them managed to reach an agreement.
According to the result of their discussion, the task of exploring the cave dwelling was to be undertaken by the three of them, whereas Zhou Chun and the other two juniors were to manage the Array outside, to prevent the valley from being exposed to the sight of other Cultivators.
Once the plan was settled, Shen Borong took out an Array Plate and set up an Array that concealed the valley.
The control of the Array, the Formation Flags, were handed over to Zhou Chun and the other two Foundation Establishment Cultivators.
In this way, even if the three faced betrayal while exploring the cave dwelling, they would have backup above ground.
